Detailed steps of vacuum water diversion by water ring vacuum pump

The air inlet pipe 6 of the water ring vacuum pump is connected to the top of the pump cover. Where there is no tap water, a gas-water separator must be provided as a water source for the cooling water and make-up water of the vacuum pump.

In the figure, the water supply pipe 4 must be connected to the air intake pipe 6. During the operation, the water of the gas-water separator is continuously supplied to the water ring vacuum pump along the pipe 4 under the action of the low pressure of the air intake pipe.
Steps for vacuum water introduction of water ring vacuum pump: First, close the sluice in the pressure pipe of the water pump, and inject water into the water ring vacuum pump. After filling the water, close the valve on the funnel, open valve 8 on the intake pipe and valve 3 on the water supply pipe, and then start the water ring vacuum pump. At this time, a mixture of water and gas is exhausted from the exhaust pipe. At the beginning, the gas in the mixture occupies the main component, and then, the water component is more and more. When all the water is water, it means that the water has completely filled the water pump, so the water is drawn Done, you can start the pump. The valve 8 on the intake pipe is closed at a fast speed, and the water ring vacuum pump is stopped.
If there are more than two water pumps in the pumping station, the inlet pipe of the water ring vacuum pump can be communicated with the suction main pipe, and the top of the pump casing of each pump is connected to the suction main pipe through the suction branch pipe. A valve is installed on each branch pipe so that each pump can be individually pumped. Sometimes, for backup purposes, two water ring vacuum pumps can be set up, and the inlet pipe of each is equipped with a valve. When one fails, the air inlet valve on the pump can be closed, and the other one can be used for air extraction without delaying the start of the pump. Under normal circumstances, two water ring vacuum pumps can pump air at the same time to speed up the water introduction rate.
