Water ring vacuum pump
Thread Content
I would like to ask what is causing the abnormal noise at the drive end of the water ring vacuum pump. I initially suspect it is a rotor clearance problem. Are there any other reasons? Also, what is the cause of the leakage in the pump body? I have re-applied sealant but it still does not work. Trachoma and corrosion have been eliminated.
The equipment manufacturer is Guangdong Kenfulai Co., Ltd., the model is 2BW5253-0NG2, the rotation speed is 920, and the pumping speed is 45-49.8 cubic meters.
It is recommended to contact the manufacturer or read the product manual for troubleshooting first.
Abnormal noise from the drive end bearing. Try replenishing grease first. If the sound does not change, then 1. The noise is caused by normal wear and tear of the bearing after being used for a certain period of time. It is recommended to replace the bearing. 2. The noise made by the bearing running circle needs to be stopped to dismantle the bearing box and the shaft diameter to determine, and then prescribe the right medicine. The leakage of the pump body is nothing more than a problem with the sealing surface between the cylinder body and the distribution plate (corrosion, cracks, etc.) or damage to the sealing gasket.
Could you please send me the contact information of your vacuum unit manufacturer?
The operating pressure of the water ring vacuum pump is very small. Generally, the essential cause of water leakage may be that the system is holding back pressure, which will cause leakage when the glue is used. It cannot be cured, and replacing the pump pad is very troublesome and of little significance. Therefore, the system pressure should be checked first. One problem is abnormal noise at the drive end bearing. The motor may be overloaded due to the pressure, and the motor bearing continues to have a high temperature. High coupling torque may cause the elastic pin of the coupling to break, causing abnormal noise at the drive end.
I don’t know how good your grouting quality is. Unreasonable settlement will affect the installation level of the rotor.
Check the vacuum level, it should be abnormal.
