Water Ring Vacuum Pump Equipment Knowledge Introduction

Start-up of water ring vacuum pump equipment: Before the long-term stop water ring vacuum pump equipment is started, it is necessary to rotate several times by hand to prove that there is no jam or other damage in the pump. First of all, we should pay attention to opening the exhaust pipe valve, then we should start the motor (pay attention to the positive and reverse of the motor); then, we should gradually increase the water supply until the water supply meet the requirements of the rules (pay attention not to dry running the vacuum pump). Stop of water ring vacuum pump equipment: When water ring vacuum pump equipment is stopped, attention should be paid to closing the valve on the intake pipe (if there is a valve in the intake pipe), and then the water supply pipe should be closed, and the vacuum pump should be shut down quickly; after stopping, attention should be paid to discharging the water in the pump chamber, so as to avoid the blade and pump shaft breaking when starting again. Water ring vacuum pump equipment: When the water ring vacuum pump equipment and the compressor are in operation, the degree of top suction on the surface of the device is concerned, and then, when the device is installed, the bolt device is used to strengthen the hole through the bottom corner. In order to avoid welding slag entering vacuum pump during installation, filter screen should be installed on suction pipe during installation.

About the device of gas-water separator in water ring vacuum pump equipment: The air-water separator can be installed directly on the exhaust port of the vacuum pump, and then it should be fixed with bolts. The air-water separator has a pipeline connected with the pump, thus supplying the working water requirement of the pump. The other working water is supplied by the water supply pipe, and the size of the water supply is regulated by the valve on the pipeline. A backstop valve should be installed on the intake pipe of the vacuum pump or the compressor so as to avoid the water in the vacuum pump or the compressor returning to the system under the pressure of the exhaust pipe when it stops. Maintenance of water ring vacuum pump equipment: When water ring vacuum pump equipment is in use, in order to prevent abrasion of impeller, pump body or blocking impeller, dust particles entering pump chamber with gas and working fluid should be washed out through the flushing port at the bottom of pump. If hard water is used as working fluid, the water ring vacuum pump must be softened or cleaned with solution in a certain period.
