The use of water ring vacuum pump has been very common, its use of water is indispensable, once the lack of water, it needs to carry out vacuum water diversion, only in this way can ensure its efficiency. What steps can we take to realize the vacuum water diversion of the water ring pump?
The intake pipe of the water ring vacuum pump is connected with the top of the pump cover. Where there is no tap water, the air-water separator must be equipped as the source of cooling water and supplementary water for the vacuum pump. The water supply pipe must be connected with the intake pipe. During the operation, the water of the gas-water separator is continuously supplied to the pump along the pipe under the action of the low pressure of the intake pipe.
First, close the gate in the pump pressure pipe and inject water into the water ring vacuum pump. After filling, close the valve on the funnel, open the valve on the intake pipe and the valve on the water supply pipe, and then start the machine.
The mixture of water and air is discharged from the exhaust pipe. At first, the gas is the main component in the mixture. Then, the water becomes more and more. When all the water is water, it means that the water is full of the pump, so the diversion is completed and the pump can be started. Close the intake pipe valve and stop the water ring vacuum pump.
If there are more than two pumps in the pumping station, the intake pipe of the water ring vacuum pump can be connected with the exhaust main pipe, and the top of the pump shell of each pump can be connected with the exhaust main pipe through the exhaust branch pipe. A valve is installed on each branch pipe so that each pump can be pumped separately.
Sometimes, for standby purposes, two water ring vacuum pumps can be set up, and valves are installed on each intake pipe. When a fault occurs, the intake valve on the pump can be closed, and another pump can be used to exhaust without delaying the start of the pump. Normally, two machines can pump water at the same time to accelerate the speed of water diversion.
