Stainless steel multi-stage centrifugal pump can be used for conveying different media, especially corrosive media. However, after long-term use, the centrifugal pump will inevitably have some failures. Therefore, it is necessary to carry out necessary maintenance during the use of the centrifugal pump. Now let’s follow Zoomlion pump to understand the daily maintenance of stainless steel multi-stage centrifugal pump.
The daily maintenance of stainless steel multistage centrifugal pump is to check whether the running sound of the centrifugal pump is normal, whether there is vibration and leakage every day. If there is a problem with the centrifugal pump, it should be handled in time. In daily use, it is also necessary to keep the stainless steel multistage centrifugal pump clean, dry, free of oil and leakage.
For the daily maintenance of stainless steel multistage centrifugal pump, it is also necessary to check whether the coupling protection cover, foundation and other screws are fastened and loose. And whether the voltage of the centrifugal pump is within the specified range, whether the appearance motor wiring and grounding are normal, etc. if the wiring of the centrifugal pump is found to be faulty, it is necessary to immediately stop using and repair the centrifugal pump.
Maintain the stainless steel multistage centrifugal pump, and check whether the motor steering is correct. When the centrifugal pump operates normally, open the outlet pressure gauge and the inlet vacuum pump to gradually open the gate valve and check the motor load at the same time.
The above is the daily maintenance method of stainless steel multi-stage centrifugal pump summarized by Xiaobian for you. I believe you will have a certain understanding of the maintenance of stainless steel multi-stage centrifugal pump after reading it.
