Why does the vacuum of water ring vacuum pump decrease in summer

Water ring vacuum pump is a new generation product developed by our company. It has the characteristics of strong corrosion resistance, high limit vacuum degree and large exhaust capacity. So why does the vacuum drop in summer when the water ring vacuum pump is used?

1. Under working conditions in summer, water ring vacuum pump adopts circulating water to cool working water. High temperature of circulating water will lead to the decrease of suction capacity and efficiency of water ring vacuum pump. Through analysis, the working water of the water ring vacuum pump is cooled by the refrigerated water of the central air conditioner of the power plant

2. Other conditions being unchanged, the lower the working water temperature, the smaller the influence on the vacuum of the water ring vacuum pump, while the higher the working water temperature, the greater the influence on the vacuum

3. For the double back-pressure condenser, due to the low pressure of the condenser corresponding to the low-pressure condenser, it is easy to find that the limit suction pressure of the water ring vacuum pump is higher than the value of the condenser pressure, so special attention should be paid to the influence of the rising water temperature of the water ring vacuum pump on the low-pressure condenser

4. Under low load condition, lowering the working water temperature can improve the vacuum effect of condenser of water ring vacuum pump
