Centrifuge failure analysis and elimination

1. Motor overheating: The motor is overheated generally in the following situations:
1.1. Generally, the starting time of the three-legged centrifuge is ≤60s. If the starting time is long, it may be throwing block wear, the weight is too light, the surface of the friction plate is oily and the motor has quality problems, so it is necessary to replace the new throwing block or Check the motor.
1.2, the starting current is large, the starting current of the general three-legged centrifuge is about 2.5 times of the rated current, and the load starting current is about 3 times of the rated current. If the current exceeds this value, there may be a quality problem of the motor, the power line Is it correct, whether the motor shaft is bent, whether the clutch is stuck, and whether the clutch throw is overweight.
2 vibration:
2.1, the large running vibration: the vibration of the centrifuge is mainly due to the imbalance of the drum quality and the gap between the drum support is too large, the bolts of the joint parts, the nut is loose. If the use time is long and the corrosion is serious, the possibility of cracking in the drum weld or other parts should be considered. Sometimes too much material is accumulated in the drum, which causes the drum to be heavy and causes vibration. Others such as spindle bending, bearing damage, etc. It is also possible to cause vibration.
2.2. Large vibration of load operation: In addition to the above reasons, the vibration of load operation is mainly caused by uneven distribution of materials, causing vibration, which can be solved by adjusting the feeding method and uniform cloth. Secondly, it may be because the drum is used for a long time, or The deformation caused by bumping, the thickness of the filter cake layer formed in the drum during use is impossible to be evenly distributed, so the machine will vibrate.
