The vacuum pumping step of water ring vacuum pump
Nowadays, the use of water ring vacuum pump is very common, finishing and use of water is not little, once the lack of water, you need to vacuum water diversion, only in this way can guarantee the work efficiency.
Vacuum pumping steps of water ring vacuum pump:
The inlet pipe of the water ring vacuum pump is connected to the top of the pump cover. In the absence of running water, the air water separator must be equipped as the water source for the vacuum pump cooling water and supplementary water. The water supply pipe must be connected with the intake pipe. In the operation process, the water of the gas and water separator will continuously supply water to the pump under the action of the intake pipe low pressure.
First, close the sluice in the pressure pipe of the water pump and fill the water ring vacuum pump. After the water is filled, close the valve on the funnel and open the valve on the inlet pipe and the water supply pipe, then start the machine.
A mixture of water and gas is expelled from the exhaust pipe. At the start of the mixture gas of ingredient, after the composition of the water more and more, until the water for all, that is fully filled with water pump, so water diversion is complete, you can start the pump.
If there are more than two pumps in the pump station, the water ring vacuum pump suction pipe can be connected with the suction pipe, and the top of each pump is connected with the suction pipe through the suction branch pipe. Install a valve on each branch so that each pump can be pumped separately.
Sometimes, for the sake of reserve, two water ring vacuum pumps can be set, each of which is fitted with a valve. When a failure occurs, the inlet valve on the pump can be closed, and another pump is used to prevent the starting of the pump. Normally, two machines can pump air at the same time to speed up the drainage.
