Compression plant cooling tower pump design, normal working pressure 0.5MPa, flow rate is 1300m3/h, but the actual operation process, the pump outlet pressure 0.75MPa, flow rate was 900 m3/h. In this operation state, not only the power consumption of the pump is high, but also the outlet flow of the pump is surplus, which causes waste.

Compression plant practicing "a penny saved is a penny earned easily" the concept of corporate culture, the impeller of two closed cycle water pump transformation. After the transformation, the diameter of the impeller is reduced from 470mm to 450mm. The flow rate of the pump is reduced by 150 m3/h, the outlet pressure is down to 0.5MPa, and the power consumption is reduced to 195kw/h from the original 250 km/h. By calculation, the company can save more than 10 million yuan of electricity every year. This small change of small leather effectively reduces the cost of production.
