How to Make Vacuum Drainage by Water Ring Vacuum Pump in Mine
Water-ring vacuum pump system is usually composed of vacuum pump, coupling, gas-water separator and pipeline. The water ring vacuum pump uses the rotating impeller to make the water or other working liquid form a rotating liquid ring. The suction gas is compressed and discharged through the liquid ring to obtain the vacuum.
A water ring vacuum pump is used to extract the gas from the suction pipe in order to form a vacuum in the sealed suction pipe and pump body, and generate negative pressure. Depending on atmospheric pressure, water is sucked from the suction pipe and pumped into the pump body. The direction of water injection is from bottom to top. With this water injection method, the vacuum in the suction pipe and pump body is stable, and the water is pressed into the suction pipe and pump body by atmospheric pressure, which overcomes the self-weight of water in the suction pipe and meets the vacuum requirement of the main drainage pump when draining water.
