Water ring vacuum pumps use water as the working fluid under normal circumstances. The purpose of vacuuming is achieved during the suction and discharge of water. During the suction and discharge of water, the water hits the pump wall, impeller, and disc. Work produces heat. If we continuously suck in water to discharge the water, it will not produce a water ring pump due to the increase in the temperature of the working fluid and the vacuum is reduced. However, in many cases, water or other working fluids are required to be recycled. At this time, it is necessary to configure a cooling tower or condenser so that the water ring pump can work normally.

A cooling tower is a heat sink, a device that uses the principle of water evaporation and heat absorption to dissipate waste heat generated in industry or refrigeration and air conditioning to ensure the operation of the system. It can lower the temperature of the cooling water. Using this principle, we can solve the problem that the temperature of the circulating fluid of the water ring vacuum pump is continuously increased and the vacuum degree is reduced. At the outlet of the water ring pump, we connect a pipeline and connect it to the cooling tower, and reduce the temperature of the water through the cooling effect of the cooling tower, and then let the water flow into the water storage tank or the storage pool, so that the water ring pump is constantly working. In this way, the temperature of the circulating fluid can be controlled, so as to solve the problem that the vacuum of the water ring pump decreases due to the increase in the temperature of the circulating fluid.

In the process of vacuum distillation or vacuum cooling, because the temperature of the pumped gas is too high, the temperature of the water ring pump will rise, thereby reducing the vacuum degree of the water ring pump. Therefore, we have to connect a water ring pump to the inlet of the water ring pump. Condenser. After cooling by the condenser, the temperature of the gas will decrease, and then it will be pumped into the water ring pump. At this time, the problem of reduced vacuum due to high temperature will be solved.
