liquid ring vacuum pump by vacuum distillation

Correct Use of Cooling Tower and Cooling Condenser of Liquid Ring Vacuum Pump

We all know that the liquid ring vacuum pump usually uses water as working fluid, in the process of water suction and discharge to achieve the purpose of vacuum pumping. In the process of water suction and dispatch, because water strikes the pump wall, impeller and disc to do work and generate heat. If we continuously use water to suck in and drain out water, it will not produce water ring pump because of the increase of working fluid temperature. Vacuum decreases, but in many cases water or other working fluid is needed to be recycled. At this time, cooling towers or condensers are needed to make the liquid ring vacuum pump work normally.rotary-vane-vacuum-pumps

Cooling tower is a heat dissipation device, which uses the principle of evaporation and heat absorption of water to dissipate waste heat generated in industry or refrigeration and air conditioning to ensure the operation of the system. It can reduce the temperature of cooling water. Using this principle, we can solve the problem that the circulating liquid temperature of the liquid ring vacuum pump keeps rising and the vacuum degree is reduced. In the drainage port of the liquid ring vacuum pump, we connect a pipeline to the cooling tower, which reduces the temperature of the water by cooling the tower, and then let the water flow into the storage tank or pool so that the temperature of the circulating liquid can be controlled during the continuous working process of the liquid ring vacuum pump, thus solving the problem of the vacuum reduction of the liquid ring vacuum pump due to the increase of the temperature of the circulating liquid.liquid_ring_vacuum_pump


In the process of vacuum distillation or vacuum cooling, because the temperature of the exhausted gas is too high, the temperature of the liquid ring vacuum pump will rise, which will reduce the vacuum degree of the liquid ring vacuum pump, so we need to connect a condenser to the inlet of the liquid ring vacuum pump. After cooling, the temperature of the gas will decrease, and then it will be pumped into the liquid ring vacuum pump, which will solve the problem of vacuum drop caused by excessive temperature.roots-vacuum-pump-for-vacuum-casting
