users in the use of direct manufacturers in the process of water ring vacuum pump work, due to continuous use, the working environment, operation technology and so on reasons, the water ring vacuum pump similar turning difficult, motor seized up, start, abnormal sound and the shortage of traffic trouble, here we combined with the actual situation to the water ring vacuum pumps use common breakdown maintenance method.

1: water ring vacuum pump turning difficult:

difficulty in turning the most for a long time not to enter after the working state of the water ring vacuum pump end surface rust, need in the pump cavity filling the oxalic acid soak for half an hour, after loosening bolts after turning smoothly after locking pump cover bolts evenly. If the conditions for use of water ring vacuum pump, users need to inspect the pump cavity temperature and dirt cleanup situation, in addition to immerse in the water pump cavity oxalate, improved process should also try to reduce the water temperature, reduce the working liquid dirt.

2: water ring vacuum pump to start the abnormal voice:

start abnormal sound when the user power supply voltage, electrical wiring, etc should be given and verified, the water ring vacuum pump users unused for a long time should be carried out to the open cover to remove the impurities and foreign body, the rusting of should add rust remover or manual derusting. Such as voice still not normal, the user should open out appropriate working liquid outlet, reason may be that the working fluid pump cavity filled with water.

3: high temperature of water ring vacuum pump:

water ring vacuum water pump temperature should be handled according to the actual situation of working liquid and gas. If the working fluid inlet temperature is too high or too little supply of water ring vacuum pump temperature is too high, the user should be to find a way to reduce the working temperature or increase the working liquid supply. If it is in gas temperature result in high temperature water ring vacuum pump, the user should be ways to reduce the suction gas temperature; Pumping gas at the compression chamber gives off heat of vaporization, the user should be in front of the pump inlet non-condensable gas condensation.

4: water ring vacuum pump motor overheating:

a motor overheating when users will motor open phase, connection should be solid, vent plug and impeller drag after given correctly, focusing on water supply lead to motor overload, and set the water supply to the parameter range.

these are in the process of water ring vacuum pump in daily use several usual faults and simple maintenance method. Relatively, efficient water ring vacuum pump failure probability is still relatively low. Water ring vacuum pump in the normal operation process, the user and equipment management personnel should pay attention to more and more observation, diligent, if there is a common fault, the above method can be used to solve. For more than common faults and not familiar with technical parameters, users avoid by all means is blind operation, should look for professionals to repair.
