在冶金、化工、电力、市政供水和采矿等行业广泛应用的泵类负载，占整个用电设备能耗的40%左右，电费在自来水厂甚至占制水成本的50%。这是因为:一方面，设备在设计时，通常都留有一定的余量;

另一方面，由于工况的变化，需要泵机输出不同的流量。随着市场经济的发展和自动化，智能化程度的提高，采用高压变频器对泵类负载进行速度控制，不但对改进工艺、提高产品质量有好处，又是节能和设备经济运行的要求，是可持续发展的必然趋势。

Pump loads, which are widely used in industries such as metallurgy, chemical industry, electric power, municipal water supply and mining, account for about 40% of the energy consumption of the entire electrical equipment, and the electricity bill even accounts for 50% of the cost of water production in waterworks. This is because: on the one hand, the equipment is usually designed with a certain margin;

On the other hand, due to the change of working conditions, the pump needs to output different flow rates. With the development of market economy and automation, the improvement of the degree of intelligence, the use of high voltage frequency converter for speed control of pump load, not only to improve the process, improve product quality is good, but also the requirements of energy saving and equipment economic operation, is an inevitable trend of sustainable development.
