The mortar pump manufacturer explained that the stainless steel mortar pump is generally divided into 304316316l and other materials, which has corrosion resistance and can transport corrosive liquids such as acid, alkali and salt. The stainless steel mortar pump is also the same anti-corrosion pump commonly used in chemical production. The stainless steel mortar pump operates by motor and completes the transmission by rotating the impeller through the pump shaft. Then the bearing supporting the pump shaft is very important, and the bearing is good or bad, Whether the operation is normal or not is related to the service efficiency and service life of the pump. For each transmission equipment, the bearing is also a common component. Check the bearing removed during regular maintenance, operation inspection and replacement of peripheral parts, so as to judge whether it can be reused or whether the service condition is better or worse. First, carefully investigate and record the removed bearing and appearance. In order to clarify and investigate the remaining amount of lubricant, clean the bearing well after sampling. Secondly, check the condition of raceway surface, rolling surface and mating surface, as well as the wear state of cage for damage and abnormalities.
1、 Inspection and troubleshooting during operation.
The inspection items during operation include rolling sound, vibration, temperature, lubrication status, etc. the specific conditions are as follows:
1. Rolling sound of bearing.
Use a sound detector to check the size and sound quality of the rolling sound of the running bearing. Even if the bearing has slight peeling and other damage, it will produce abnormal sound and irregular sound, which can be distinguished by the sound detector.
2. Temperature of bearing.
The temperature of the bearing can generally be inferred from the temperature outside the bearing chamber. It is more appropriate if the oil hole can be used to directly measure the temperature of the outer ring of the bearing. Usually, the temperature of the bearing rises slowly with the start of operation and reaches a stable state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are appropriate, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, the operation must be stopped and necessary preventive measures must be taken. The thermal sensor can monitor the working temperature of the bearing at any time, and automatically alarm or stop when the temperature exceeds the specified value to prevent the occurrence of combustion shaft accident.
