Running process of liquid ring vacuum pump
Liquid Ring Vacuum Pump were originally used as self-priming pumps. It is composed of impeller, pump body, suction and exhaust disc, water ring, suction port, exhaust port and auxiliary exhaust valve formed by water in the pump body wall.
In many industrial production process, such as vacuum filter, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, liquid ring vacuum pump is widely used. As a result of the rapid development of vacuum application technology, liquid ring vacuum pump has been paid much attention in the acquisition of crude vacuum. Because the gas compression in liquid ring vacuum pump is isothermal, it can take out inflammable and explosive gas, and also can take out the gas containing dust and water. Therefore, the application of liquid ring vacuum pump is increasing day by day.
Liquid Ring Vacuum Pump everyone must have heard how to operate it you know, let the small editor tell you.
1.Operation process of water ring vacuum pump:
1. Prepare before opening liquid ring vacuum pump
(1) check. Carefully check the connection between the parts.
(2) to open. Open the water inlet valve of the water tank and fill the water tank to the specified water level; Open the suction valve and discharge valve of the vacuum pump.
(3) closed. Close the vacuum whose inlet valve and drain valve.
2. Open liquid ring vacuum pump:
When everything is ready, the pump can be started. When the vacuum tank reaches a certain vacuum degree, the pump valve can be opened and the centrifugal pump can be pumped. The operation of the vacuum pump is the same as that of the centrifugal pump when the bottom oil is removed from the tank truck.
3. Maintenance during operation of vacuum pump:
During the operation of the pump, the staff should strictly observe the position, concentrate their energy, observe carefully, and achieve:
(1) listen and listen to whether the pump and motor are working normally.
(2) see whether the vacuum degree, the height of the liquid level of the vacuum tank, the circulating water in the tank and the bearing lubrication are normal.
(3) touch, and touch whether the bearing and motor temperature are normal by hand.
4. Stop the vacuum pump:
(1) first close the suction valve, then open the air inlet valve of the vacuum tank, and finally stop the pump.
(2) air vacuum valve. Close the valve.
