1. Influence of abnormal vibration of multi-stage pump on bearing During the use of multi-stage pump, abnormal vibration damage to the bearing is very obvious, such as peeling, indentation, rust, crack, wear, etc., which can be reflected. The size of abnormal vibration of the water pump can be measured by the bearing vibration measurer, and the abnormal situation of the water pump can be inferred by the vibration frequency distribution. The measured value will be different due to the use conditions of the bearing or the installation position of the sensor, therefore, Changsha Zhonglian Pump Industry needs to analyze and compare the measured values of each machine before determining the judgment standard. 2. The influence of multi-stage pump temperature on bearing Bearings that have been in high temperature for a long time are very unfavorable. Sometimes the overheating of multi-stage pump bearings is due to the lubricant of the bearings. If the multi-stage pump bearings are operated in an environment of 125 ℃ for a long time, the service time of the water pump will be reduced, resulting in insufficient lubrication, excessive lubrication, impurities in the lubricant, excessive load of the water pump, bearing damage, insufficient bearing clearance, high friction caused by the oil seal of the water pump, etc. 3. Post-treatment measures for bearing temperature rise of multi-stage pump Multi-stage pumps are prone to temperature rise during use. When the temperature of the water pump bearing rises, it is first necessary to find out whether the bearing temperature rises due to misoperation. If the bearing temperature does rise, you need to do The following measures are used for cooling: 1. First check whether the water pressure, water flow and pipeline system of the water pump are normal. If the water pressure is too low, the filter of the water pump will be blocked. If it cannot be handled in time, it is recommended to stop the machine as soon as possible, and then start the operation after the fault is confirmed to be eliminated; 2. Check the oil pressure of the water pump governor. If the water pump oil pressure is too low, the water pump cooling water hydraulic valve will be closed; 3. Check the abnormal sound of the water pump bearing and check whether the swing of the water pump bearing is abnormal; 4. Check whether the lubricating oil of the water pump is abnormal, and check whether it has deteriorated. If it is confirmed that it has deteriorated, stop the machine and replace it with new lubricating oil; 5. Check whether the lubricating oil level of the water pump is normal. If it is not normal, check whether the oil drain valve of the oil tank is closed tightly. If the oil drain valve of the oil tank is closed tightly, add lubricating oil. If the sealing rubber pad is leaking oil, stop the machine.
