The above phenomenon occurs after the normal use of the high-pressure centrifugal fan frame for several years. The movable support is composed of upper and lower bolts and an adjusting nut. The main reason is that the frame has been 'fatigue' under the action of the dynamic load of the fan rotor for a long time. The adjusting nut is a counter-thread nut. The upper screw is a left-handed screw thread and the lower screw is a right-handed screw thread.

The high-pressure centrifugal fan can solve the problem on site by adopting the following technical measures: when there is no rotor load, sweeping robot bearings suppliers strengthen the frame. The rigidity of the frame begins to weaken.. Under the effect of static and dynamic loads Deformation deflection increases. Carry out adjustment and inspection when the bearing is installed in place and the bearing is not installed. The screw can adjust the length of the screw.

It is welded on the upper and middle frames. Under the static load of the fan rotor, slowly rotate the adjusting nut, and then check the bearing ball force situation until the bearing force condition is consistent with the normal force condition described above, and lock the upper and lower lock nuts. The adjustment is completed.

manufacturer professionally analyzes the reasons for its possible causes: the safety factor of the load is too small when designing the rack; the steel used in the rack does not meet the steel standards of the design requirements; the fabrication and welding of the rack do not meet the design Claim. At the vertical centerline position, a movable support with adjustable height is installed on the upper frame and the middle frame. At the vertical centerline position of the rotor shaft, a vertical support is added between the middle cross frame and the lower crossframe
