Packaging Protection of Long Magnetic Rods(2022年)

leyuangroup — 2022-11-01T15:42:17+0900

https://www.leyuangroup.com/packaging-protection-of-long-magnetic-rods.html

Many manufacturers only pay attention to the permanent magnetic rods which should not be damaged during transportation, but they do not have enough experience paying attention to the deformation of the magnetic rods caused when the customers take out the magnetic rods after receiving the goods. This phenomenon will occur in long-size magnet products with a strong magnetic field:

After several magnetic rods are packed, because of the strong suction force, they are tightly attached together. We can't pull out a single magnetic rod at all. Most customers will grab one end of a single magnetic rod and lift it up forcefully. If the suction force is too strong, it will cause the magnetic rod to bend and deform during the lifting process.

When packaging, we first wrap it with moisture-proof paper to avoid scratches on the surface, and put it into a plastic pipe. The two ends of the plastic pipe are sealed with a cover to prevent dust from entering. At the same time, several short pipes are placed. The function of the short pipes is to increase the distance between the magnetic rods, because the suction force is proportional to the square of the distance, increasing the distance will reduce the suction force and avoid the bending of rods.

The magnetic rod adopts permanent magnets, and no additional energy is needed. It can remove the iron impurities in the materials to achieve the function of purifying the materials and protecting the equipment. The magnet rod is welded by argon arc welding, and the whole body is sealed and waterproof. And the surface roughness reaches RA0.6 after 4 polishing processes. The magnetic rod is completely covered by stainless steel, sealed and welded, which can effectively resist the erosion of acid and alkali solutions. Different from simple magnets, the magnet rod is composed of multiple magnets to form a magnetic circuit, which improves the magnetic field strength, which is twice that of a single magnet, so that the magnet rod can better absorb fine particles.

Pros and Cons for Magnetic Springs in Furniture(2022年)

leyuangroup — 2022-11-01T15:41:53+0900

https://www.leyuangroup.com/Magnetic-Springs.html

How we service our customer, help him to finish his idea and optimize the products to meet the efficient cost.
First we have received an client enquiry regarding customised magnetic assemblies, they inquired

Diameter: d=9 mm

Return Force: F=20/30 N

Multiple magnetizations on the outer diameter as shown in figure

According to our experience, for a 9mm diameter magnet to reach a return force of 30N, it has to be a sintered neodymium-iron-boron magnet. However, there is no manufacturer in China capable of manufacturing a four-pole magnetic tube.

We have devised a different solution to address this, which is to make and then stack tile-shaped magnets one by one according to the magnetic circuits requested by the client. We provided a rough production process to elaborate on what LEYUAN intends to do.

Step 1: Make a steel rod.

Step 2: Glue tile-shaped magnets one by one on the rod into the magnetic tube as requested by the client.

Step 3: Make a stainless steel tube with an inner diameter larger than the outer diameter of the rod made earlier.

Step 4: Insert the said rod into the tube to complete the magnetic tube.

This proposal allows us to deliver magnetic circuits as requested by the client, and the return force can be tuned through adjusting the thickness of the tile-shaped magnets. However, this proposal was rejected by the client as it was costly.

Second, after having full understanding of the client's intended use for the magnetic tube, we know that the most crucial part of the project is the return force, which allows us room for designing the optimal solution to the problem.

A four-poles circuit is unnecessary, hence we change it into a two-poles one.

A 90mm long rod magnet can only be wire-cut in the manufacturing process, which is costly. As such, we will separate it into three sections, allowing the magnet to be cut conventionally, reducing cost significantly:

How do we install all three sections of the rod magnet, allowing them to be unaffected by repulsive force and kept in a straight line? We designed a fixture to reduce difficulty of Magnetic assembly, and increase consistency.

The completed product is as shown below:

As a magnetic products supplier, Leyuan Group has been an experienced magnetic products supplier/manufacturer in China since 1995. We manufacture a range of main magnetic products comprising magnetic filters, magnetic couplings, permanent magnets, and customer design magnet assemblies.

What is a Magnetic Coupling?(2022年)

leyuangroup — 2022-11-01T15:41:29+0900

https://www.leyuangroup.com/what-is-a-magnetic-coupling.html

Magnetic Coupling Definition
The magnetic coupling transmits a force without any actual physical contact. Due to the attraction and repulsion of magnetic force, its effect can be linear or rotating. A simple magnetic coupling motor has a follower and a driver. The driver is connected to a motor, and the follower reacts to the motion of the driver, which causes the transmission of mechanical energy without contact.

Understanding magnets can effectively help to understand magnetic couplings. The magnet generates a magnetic field or force. This force acts on ferromagnetic materials, pulling them together or pushing them away. Ferromagnetic materials include iron, cobalt, nickel, and certain alloys. The total strength of a magnet is measured by what is called its magnetic moment, or a permanent magnet is made of a material with its own constant magnetic field. Similarly, an electromagnet is composed of a coil, and when current passes through the coil, the coil becomes a magnetic field. When current passes through the coil, both the coil and the coil have only magnetic force. When the current change in one conductor generates a voltage in the second conductor, both conductors are magnetically coupled.

Drive Device of Magnetic Coupling
In the rotary drive motor, the magnetic drive coupling is composed of internal and external drive devices. The movement of one drive device provides magnetic force to turn the other drive device. The external drive device is usually called a drive device. The internal drive device is a follower device, usually connected to a pump or other device. This radial design is similar to an electric motor.

The driving device is used for pumps with corrosive, flammable or toxic liquids, and magnetic couplings are usually used to use permanent magnets. These permanent magnets can be sealed so that they do not come into contact with liquids. The rotor is held together by magnetic force and will not slide during rotation. However, if too much external force is applied, the magnet will separate and the drive pump will stop.
Advantages of Magnetic Coupling
One of the advantages of magnetic coupling is to reduce vibration. It can also set an isolation barrier between the follower and the driver, because even if the magnetic drive system and the follower are in different environments, they can transmit force. Since the magnetic force will still work, alignment is not important. The coupling can also work along an axis that provides linear force.

Another advantage of motors using magnetic couplings is that they reduce contact between moving parts. Unlike direct contact, there is a gap between the motor and the load it drives. This can reduce friction and improve efficiency. It can also reduce the wear and tear of the motor, thereby extending its service life.

What Factors Will Affect the Price of NdFeB Magnets?(2022年)

leyuangroup — 2022-11-01T15:41:04+0900

https://www.leyuangroup.com/what-factors-will-affect-the-price-of-ndfeb-magnets.html

The ndfeb price is high or low. What causes the quality and price of NdFeB magnets to be affected? It can be explained mainly from two aspects.

Ⅰ. What are the factors that affect the processing cost of NdFeB magnets?
Generally speaking, the factors affecting the processing cost of NdFeB mainly include the following aspects:

1. The performance requirements, batch size, specification shape and processing tolerance size of NdFeB magnetic product.

2. The higher the performance requirements of NdFeB magnet processing, the higher the cost. For example, the price of N45 magnet is much higher than that of N35.

3. The smaller the batch of NdFeB magnet processing, the higher the processing cost.

4. It is related to its specifications and shapes. The shapes are divided into conventional and special shapes. The more complex the shape of the neodymium iron boron magnet, the higher the processing cost.

5. Related to tolerance size: especially small NdFeB magnets, used in micro precision instruments, have very strict tolerance regulations; if the process cannot be achieved, manual selection is required, and it has a high scrap rate and a cost. Higher.

Ⅱ. Market conditions affect the price fluctuations of NdFeB magnets
One is policy support. If the national policy fails to keep up with the demand of market development, the market development is unbalanced and speculators are hyped, the price of strong neodymium bar magnets will also be deeply affected. The second is technological level. At present, new energy is a project advocated by various countries, and companies have launched energy-saving markets to manufacture new energy vehicles. The invention and launch of new energy vehicles have had a great impact on this industry. Therefore, technological innovation also affects a magnet market to a large extent.

The above is an introduction to the factors affecting the price of NdFeB magnets. If you have any questions about NdFeB magnets, follow us for more relevant information.

Our company is one of experienced magnetic assembly manufacturers. We focus on the production of magnetic products related to permanent magnets. We have a large number of in-house manufacturing and value-added finishing operations. Our technical application team also has a wealth of expertise in the application of magnetic technology, providing customers with CAD and 2D / 3D simulation support and solution optimization.

The Working Principle of Magnetic Coupling(2022年)

leyuangroup — 2022-11-01T15:40:40+0900

https://www.leyuangroup.com/the-working-principle-of-magnetic-coupling.html

What Is Magnetic Coupling

Magnetic coupling is a new transmission mechanism and a pure mechanical product without the limitation of working environment. It is more suitable for flammable and explosive environment.

Because the permanent magnetic coupling is a transmission device that transmits torque through the magnetic field, and there is no mechanical connection between the magnetic coupling motor and the load shaft. When the motor rotates, the magnetic field lines are cut in the strong magnetic field generated by the permanent magnet rotor made of the copper magnetic disk on the magnetic rotor, which creates vortex in the disk, and the vortex currents make relative movement between the conducting rotor and the permanent magnet rotor. The functions of torque transmission and speed regulation can be achieved by adjusting the air gap between the rotor and the permanent magnet rotor as well as changing the size of the magnetic field.

Magnetic Coupling Design
Magnetic coupling is divided into inner and outer magnets. Magnetic coupling principle is a process of driving the outer magnet through the motor, and then the outer magnet transmits the power to the inner magnet. The inner and outer magnets are completely in two different spaces, so it is a force transmission without any media.

How does a magnetic coupling work?
Permanent magnet coupling is divided into various structural forms. Under the principles of magnets attracting each other, the inner and outer rotors are assembled with super-strong magnets. When the magnetic coupling motor drives the outer rotor, the energy is transmitted to the inner rotor through the magnetic circuit so that the inner rotor rotates synchronously. This permanent magnetic coupling achieves static sealing because the internal and external drive shafts are not hard-wired; thus, they are widely used in transportation systems for corrosive, toxic, and contaminated liquids or gases.

How does a magnetic coupling work?

Magnetic coupling device can be regarded as a qualitative leap in the reaction still industry, which has greatly solved the shortcomings of mechanical seal and many problems that could not be solved before in production test zones of chemical and pharmaceutical industries, and also solved the high temperature, high pressure, flammability, explosiveness and leakage problems of the reaction still.

Samarium Cobalt(2022年)

leyuangroup — 2022-11-01T15:40:17+0900

https://www.leyuangroup.com/products/samarium-cobalt/

As one of the samarium cobalt magnet suppliers and mco magnet manufacturers, Leyuan would like to introduce you samarium cobalt pot magnet which come in energy products from 16MGOe up to 33MGOe. Their high resistance to demagnetizing influences and excellent thermal stability has ensured Sm-Co as the premium choice for the most demanding motor applications. In addition to this, the corrosion resistance is significantly higher than, for example, Nd-Fe-B. It is still recommended to coat the magnet in acidic conditions. Its corrosion resistance has also offered a high degree of comfort to those looking to use magnets in medical applications.

he Specification of Samarium Cobalt Magnets

Its smco magnet properties are not too far from Neodymium Iron Boron magnets but, due to the cost and strategic value of Cobalt, it never had the commercial success and diffusion of NdFeB. Being a rare earth magnet, it is an intermetallic compound of rare earth metals (samarium) and transition metals (cobalt). The production process consists in milling, pressing, and sintering in an inert atmosphere: magnets are then pressed in an oil bath (isostatically) or in a dye (axially or diametrically). SmCo is processed by grinding with diamond tools. As mentioned, SmCo can provide high magnetic performances, with maximum energy production of around 240 KJ/m3: they can be found in two different grades, Sm1Co5 and Sm2Co17, and each one has its own specific magnetic behavior (nucleation for the first, pinning in Sm2Co17). Sm2Co17 shows the highest magnetic performances but, on the opposite side, it is much more difficult to be magnetized (4000 kA/m) than Sm1Co5 (2000 kA/m). The two advantages of SmCo grades versus NdFeB are the corrosion resistance and the good thermal behavior; Curie temperature is around 750°C for Sm1Co5 and 850°C for Sm2Co17 . Furthermore, the rate of magnetic properties decrease is rather low by increasing the temperature. SmCo grades are best appreciated in military and aerospace industries, as well as in the electromedical field; they should be preferred when oxidation or thermal needs become very important. Its industrial applications are similar to the ones of NdFeB: sensors, loudspeakers, electric motors, instruments, and switches.

As a professional smco magnets supplier and samarium cobalt magnet manufacturer from China, Leyuan has the samarium cobalt magnets for sale. If you want to know samarium cobalt magnet price, please contact Leyuan or leave a message through our website.

Pot Magnets Without Bore(2022年)

leyuangroup — 2022-11-01T15:39:53+0900

https://www.leyuangroup.com/products/pot-magnets-without-bore/

Coating one surface of the magnet with an iron sheet means that the magnetism of the coated surface is shielded and the magnetic lines are guided to the other surface so that the magnetic force of the other surfaces is strengthened. For some magnet applications, only the magnetic force of one side is needed, while the other side of the magnetic force could cause interference; in some applications, only one side of the magnet can be used, and the other side not used, which is not essential. This can lower the cost and savings of the amount of magnetic material used.

As one of the most professional pot magnets manufacturers from China, our pot Magnets without bore are strong round flat magnets. They are flat, round magnets and only one side have magnetism; they are widely used in moon cake boxes, mobile phone boxes, suitcases, leather, etc.

Magnetic Trap Food Industry(2022年09月19日)

leyuangroup — 2022-09-15T18:05:38+0900

https://www.leyuangroup.com/food-processing-with-magnetic-filter.html

Magnet Trap Powder Industry
Magnetic separation products are becoming more common in the food industry. When magnetic separation products are working in the food processing, metal fragments are easily to be left in the grinder, sometimes even raw materials. Metal fragments pose a safety risk to consumers and can even damage processing equipment. So inline magnets for food processing is definitely necessary.

Magnets in Food

Applications Of Food Processing Magnets
Incoming material filtration: such as particle, rhizome, leaf, etc, raw materials magnetic filtration, The raw materials are primarily sorted to ensure the normal operation of subsequent processes.

Iron removal after chopping: iron impurities dropped from the cutter after block raw materials are chopped will damage the human body and lead to excessive iron content, so it is necessary to remove these contaminants by the filtration of inline magnets for food processing.

Grinding powder: the abrasion of grinding equipment produces secondary pollution. For example, in the ball mill, when the raw material changes into powder, the abrasive iron ball will also drop into the iron powder; the magnetic filter is used to remove the iron powder produced in the process.

Mixing: Dry powders, particles, liquid or slurry. In the process of mixing, it is necessary to use a cutter to stir. When the cutter and the material are rubbed, it is inevitable that wear will occur, so the iron powder or iron particles will be mixed into the material.

Before packaging processes: Before the product leaves the factory, magnetic filtration is carried out for the last time to remove iron pollutants and to ensure the iron content of product reaches the necessary standard.

As one of magnetic assembly manufacturers, we will do our best to meet all the needs of customers.

Differences between Dry Magnetic Separator and Wet Magnetic Separator(2022年09月18日)

leyuangroup — 2022-09-15T18:05:10+0900

https://www.leyuangroup.com/differences-between-dry-magnetic-separator-and-wet-magnetic-separator.html

Differences between Dry Magnetic Separator and Wet Magnetic Separator
Ⅰ. The introduction of dry high intensity magnetic separator
Dry magnetic separator is the mainstream of magnetic separation equipment, which is also used for industrial low intensity magnetic separator earlier. It is suitable for arid areas and can separate large and coarse ore with strong magnetism as well as fine ore with weak magnetism through simple process. Common dry magnetic separation equipment includes: dry low-intensity magnetic field magnetic separator (in addition to ironware and magnetic pulley) and dry high-intensity magnetic field magnetic separator (induction roller magnetic separator, dry electromagnetic disc type high-intensity magnetic separator and dry roller magnetic separator).

Dry magnetic separator has high requirements on the material. The material that needs to be separated should be dry with an independent and free form, otherwise the separation effect will be affected. In addition, the efficiency of dry magnetic separators is mainly restricted by three factors: roller speed, baffle position and ore size.
Ⅱ. The introduction of a wet magnetic separator
Wet low intensity magnetic separators are industrial magnetic separators widely used in iron ore concentrators. They can not only be used for separation operation but also replace the magnetic dewatering tank as the concentration equipment before filtration. The process is complicated, and water is needed as the medium for separation. The common wet magnetic separator includes wet low intensity magnetic separator (magnetic dewatering tank) and wet high intensity magnetic separator (wet induction roller type high-intensity magnetic separator, Jones type high-intensity magnetic separator and flat ring magnetic separator). According to the tank structure, wet magnetic separators can be divided into the current wet magnetic separators, countercurrent wet magnetic separator and semi-countercurrent wet magnetic separators.

Wet magnetic separators can save energy and reduce consumption, effectively utilize extremely lean iron ore and improve the quality of final iron concentrate，which is the preferred choice of the supplier of the magnetic product. They are generally used for selecting fine strong magnetic ore, weak magnetic ore, and iron powder.

Ⅲ. Differences between dry and wet magnetic separators
(1) Different feeding

Dry magnetic separators can separate the ore whose humidity is below 5%, and the beneficiation process of wet magnetic separators must rely on water as the medium.

(2) Different feeding granularity
Dry magnetic separators are used for selecting large and coarse ore with ferromagnetism and fine ore with weak magnetism (beach sand). Wet magnetic separators are used for separating fine strong magnetic ore and fine weak magnetic ore.

(3) Different techniques

Dry magnetic separators can realize mineral separation without water, and the technique process is simple, while the process flow of wet magnetic separators is complex.

Attention Must Be Paid Attention to These Aspects of Storing NdFeB Magnets(2022年09月17日)

leyuangroup — 2022-09-15T18:04:43+0900

https://www.leyuangroup.com/attention-must-be-paid-attention-to-these-aspects-of-storing-ndfeb-magnets.html

Attention Must Be Paid Attention to These Aspects of Storing NdFeB Magnets
There are several aspects of storing neodymium magnets that everyone must pay attention to. Here we can give you a brief introduction, because we all know that its use range is very wide, and its development history is also very long, so preservation is also very important. If you are interested, you can come with us to see how to save it.
1. Avoid storing NdFeB magnets in high temperature and high humidity environments

There are many things to pay attention to after NdFeB is formed, especially when it is stored. It is very important to avoid placing NdFeB magnets in a humid environment during storage.
If placed in a humid environment, some properties of NdFeB magnets may be affected, and the magnetism of NdFeB magnets may be weakened. It is also important that when NdFeB is stored in a humid environment, its appearance and physical properties may change.

Because some special NdFeB magnets will weaken or even disappear in a high temperature environment, this is a very troublesome thing for practical applications, so do not store NdFeB magnets in a high temperature environment, this still requires special attention

2. Try to store NdFeB magnets separately
This is to prevent the NdFeB from being damaged by collisions, which may cause it to be unable to be used normally. Do not store NdFeB magnets close to certain electronic instruments, such as disks, tapes, etc., otherwise it may cause circuit failures of electronic instruments and affect their use, especially some magnetic storage devices.
3. When storing NdFeB magnets, try not to get close to the magnetic recording equipment
When storing NdFeB, try not to get close to magnetic recording equipment such as floppy disks, credit cards, kinescopes, etc. If you are close to these devices, NdFeB may affect or even destroy some of the data they record. This is a troublesome thing, so we have to remember.

When storing NdFeB magnets, if a person who is sensitive to metals approaches the neodymium iron boron, some reactions may occur, such as redness of the skin. Therefore, people who react to metals should not take the initiative to approach the neodymium iron boron, otherwise it may cause some unhealthy physical conditions.
We must pay attention to the preservation of NdFeB magnets. Strictly speaking, it can also be said to be part of the NdFeB process. The preservation of NdFeB is also a very important aspect for practical applications and should be paid attention to.

As a magnetic products manufacturer, we can also offer kinds of magnetic grate separators for sale, anything you need, please leave us a message.

There are several aspects of storing NdFeB magnets that everyone must pay attention to. Here we can give you a brief introduction, because we all know that its use range is very wide, and its development history is also very long, so preservation is also very important. If you are interested, you can come with us to see how to save it.

1. Avoid storing NdFeB magnets in high temperature and high humidity environments
There are many things to pay attention to after NdFeB is formed, especially when it is stored. It is very important to avoid placing NdFeB magnets in a humid environment during storage.

If placed in a humid environment, some properties of NdFeB magnets may be affected, and the magnetism of NdFeB magnets may be weakened. It is also important that when NdFeB is stored in a humid environment, its appearance and physical properties may change.

3. When storing neodymium magnets, try not to get close to the magnetic recording equipment

When storing NdFeB, try not to get close to magnetic recording equipment such as floppy disks, credit cards, kinescopes, etc. If you are close to these devices, NdFeB may affect or even destroy some of the data they record. This is a troublesome thing, so we have to remember.

We must pay attention to the preservation of NdFeB magnets. Strictly speaking, it can also be said to be part of the NdFeB process. The preservation of NdFeB is also a very important aspect for practical applications and should be paid attention to.

Custom Powerful Magnet(2021年)

leyuangroup — 2021-08-06T11:27:14+0900

https://www.leyuangroup.com/products/custom-design-magnets.html

Customized magnets are used in corrosive liquids. The magnet is required to be completely covered in a stainless steel SS316 shell and welded by argon arc welding. The whole is waterproof and anticorrosive sealed welding, and the end welding bolts are used for installation. The size of the magnetic component is 120mm in diameter, 50mm in height, and the magnetic field strength is above 8000Gs.

Production process:

Due to the large size of the custom made magnets and the strong magnetic field, it cannot be made by conventional technology. We carefully studied the structure and production process of the magnetic component according to the customer's requirements. The first is to complete the welding of the stainless steel 316 shell, thereby leaving room for assembly. Then we designed and manufactured an assembly bracket, which uses a jack to assemble the powerful N52 magnet and control the position, so as to prevent the magnet from flying out and hurting people due to the principle of same-sex repulsion. In the third step, the welding worker first uses a small current to weld the seal of the magnetic device in place, and then uses a high current to weld the seal as a whole. Finally, it is polished into a beautiful finished magnetic product.

The Application of Magnetic Coupling in Roller Press Drive System(2021年)

leyuangroup — 2021-08-06T11:25:06+0900

https://www.leyuangroup.com/products/magnetic-coupling/

Ⅰ. Magnetic coupling is an ideal green product
In order to protect cement machinery and equipment, hydraulic coupling is often set in the transmission system of equipment to realize flexible start and reduce the impact of starting equipment. But in actual operation, oil leakage and other problems are easy to occur in hydraulic coupling. The magnetic product is a new technology and an ideal green product to achieve the indexes of safety, reliability, energy-saving and consumption reduction, therefore, the magnetic drive system, a new type of flexible protection device, is used by the magnetic products manufacturer in the transmission of roller press, and the operation effect is very good.

Ⅱ. The technical schemes of pot magnets in roller press transmission system
1. The roller press transmission system is provided with a telescopic universal joint, so there must be relatively fixed foundations on both sides when installing the magnetic coupling. Concrete ground foundation should be poured next to the motor through field measurement. On the basis of the bearing seat, the magnetic coupling can be installed between the bearing seat and the motor, and the bearing seat is connected with the reducer through the retractable universal joint, so as to realize the transmission of the roller press. The foundation can be constructed and maintained during production without affecting production at all.

2. Install the magnetic coupling on the motor shaft, and install the running end on the specially made support device. The support device is placed on the newly added concrete foundation, which bears most of the weight directly. The universal joint is connected with the reducer and the supporting end, and the magnetic coupling will not move during operation, which greatly reduces the vibration of the transmission system.

3. In order to make it convenient and fast to disassemble and install the magnetic coupling when maintaining the main motor, the expansion sleeve connection is designed between the magnetic coupling and the motor, between the magnetic coupling and the reducer or the bearing seat. When repairing the motor, the magnetic coupling can be separated from the motor as long as loosening the expansion sleeve.
