Dealing with abnormal sound of plastic non-leakage magnetic pump! ~If you find any abnormal sound from the non-leakage magnetic pump, you should stop the machine immediately and check the cause. When the leakage-free magnetic pump is to be stopped, first close the gate valve and pressure gauge, and then stop the motor. No leakage magnetic pump at work * * * Within a month, change the lubricating oil every 100 hours, and then every 500 hours. Frequently adjust the packing gland to ensure normal dripping in the packing chamber (it is better to keep dripping out). If the leak-free magnetic pump is not used for a long time, the pump must be completely disassembled, the water must be wiped dry, the rotating parts and joints should be coated with grease and installed, and kept properly. Regularly check the wear of the shaft sleeve and replace it in time if the wear becomes severe. Pay attention to the stability of the operation of the leak-free magnetic pump, because the leak-free magnetic pump often needs to transport some sensitive and dangerous media, so some problems may occur during use. What we have to do is to maintain its normal operation, prevent safety problems, and keep it as stable as possible. Pay attention to reducing friction. If we want the leak-free magnetic pump to operate normally for a long time, in fact, reducing friction is very effective.
