1. Pump severe vibration reason contact electric rotor imbalance or coupling Qianan, bearing wear, twists and turns, change some parts of loose, broken pipe support is not strong. Can adopt adjust, repair, reinforcement, straightening, replacement and other disposal measures.
2. Pipe leakage or leakage may be due to the installation of a screw cap screw. If the leak is not severe, can be used in cement, mud or soft soap, leaks or leakage. If the joint leakage, can tighten the nut by hand. Severe water must be re assembled.
3. Packing packing is too tight for overheating and more, less or cooling water into the damage caused by the shaft of the packing material. Relaxation can adopt appropriate packing, finishing sealing pipe blockage, etc.. New packing wear must be replaced, installed in front of the oil immersed in the oil, by the turn of the mountain. The incision to be staggered, so as to reduce the leakage. Install to install the final lap of the packing gland, then adjust tightness during operation.
4. Not pump water or drainage multiple reasons for the end of valve stuck, some silt water disposal, water height is too high or the leakage may also is due to power resulted in a shift of the impeller, the road is blocked. Through the check one by one, were adopted at the end of valve repair, remove the blockage, the correct steering and clean the impeller and other ways to cope with.
