Three-legged centrifuge drum and spindle maintenance methods
Edit:Guangzhou Fuyi Liquid Separation Technology Co., Ltd.   PublicDate:2017-11-20

Three-legged centrifuge drum and spindle are the most important components, in order to extend the service life of the three-legged centrifuge for the maintenance and repair of the machine is necessary, the following for the two main components to say Good machine protection and repair.

       First, three-foot centrifuge drum maintenance methods

A three-foot centrifuge used six months after the centrifuge should be renovated once, we also have to maintain the centrifuge in their daily work, centrifuge drum is an important part of the centrifuge, but also need to do a good job of maintenance, The following is the maintenance of the three-legged centrifuge drum:

1, check the drum appearance. If cracks, pitting and other defects should be repaired welding, repair welding the total length of the drum should not exceed 10% of the length of the weld. With a magnifying glass to inspect the appearance of the weld quality, there should be no pores, slag, cracks and other defects, the other weld undercut depth of not more than 0.5mm, or should be re-welding. Weld repair at the same number of times should not be too much, stainless steel time, carbon steel for the second, repair the weld is longer, the drum to heat treatment and calibration static balance.

2, check the drum wall thickness. If the wall thickness l / 3, it should be replaced. After the replacement of the drum must be together with other components mounted on the spindle, the entire rotary body school dynamic balance.

3, check the drum radial runout and roundness deviation (radial runout should not exceed 0.0001D, roundness deviation should not exceed 0,0002D, D is the diameter of the drum).

Second, three-foot centrifuge spindle maintenance rules:

1, check the spindle journal wear. If the wear depth is not too large, wear parts can be surfacing or plating repair, and then processed to the original size; If the wear depth is too large, it should be replaced with a new shaft.

2, the spindle inspection. If there are cracks, corrosion and other defects, are not allowed to repair, but can only be replaced.

3, testing the deviation of the straightness of the spindle. If the straightness or concentricity deviation exceeds the allowable value, the spindle should be corrected; if it is too large, it should be replaced.

4, check the surface of the neck with the processing of the surface quality. Surface roughness value R <6.3m, and="" without="" scratches,="" grooves="" and="" other="">
