Bearings are important components of multi-stage pumps. If the bearings are overheated during use, it indicates that there is a problem with the use of multi-stage pumps. We need to stop the pump check. In addition, if the bearing wears out, it will affect the normal operation of the pump. Therefore, it is necessary to do a good job of bearing maintenance and learn how to judge whether the bearing is worn or not. In addition to this, the bearings should be cleaned. When cleaning the imported bearings, the bearings should be removed for inspection, and the appearance should be recorded. At the same time, the lubricant should be inspected and the lubricant should be sampled. After doing these two things, you can start cleaning the bearings. The cleaning agent used should be neutral and should not contain water diesel or kerosene.
There are two steps to cleaning the bearing. The first step is rough washing and the second part is fine washing.
When rough washing, it should be brushed in the oil, and the surface of the grease and some attachments should be washed. Avoid washing the bearings when washing, otherwise the rolling surface may be damaged. When rough washing, the adhesives and foreign objects are mainly cleaned. Then, when the finish is cleaned, you can start to rotate the bearing and carefully clean it. When moving the bearing, the action should be slow, and the cleaning must be careful.
When the multi-stage pump is in use, the bearing keeps running, and there are some problems in the shaft hole. Therefore, we should not forget to repair the shaft hole while cleaning. First check the depth of the shaft hole wear. If the radial direction is less than two millimeters, you can use a power tool to polish it. Do not grind it too fine when grinding, and the roughness is better. Apply the repair agent to the outer ring of the bearing to ensure that the shaft hole and the outer ring are filled with the repair agent.
Generally, when we use multi-stage pumps, we are transporting particulate matter. Therefore, in order to avoid blocking the multi-stage pump with large particulate matter, we should set up a filter in the inlet pipe to block relatively large particulate matter. . After one day of work is completed, it should be transported with water for half an hour to rinse the sand in the pump.
