Description
技术领域 technical field
本实用新型涉及节能降耗技术领域，具体说涉及一种电动离心泵节能控制装置。The utility model relates to the technical field of energy saving and consumption reduction, in particular to an energy-saving control device for an electric centrifugal pump.
背景技术 Background technique
在连续的化工生产过程中，使用电动离心泵外送液体时，通常设计成两台相同功率的电动离心泵并联使用，一台运转，另一台备用。由于各方面因素的影响，外送液体的流量会发生改变，当流量变小时，电动离心泵的电耗不会发生变化，这也就相应的浪费了电能。随着科技的发展，市场上出现了电动机变频技术，对节约电能起到了一定的作用，但是电动机变频技术复杂、费用较高，不利于节省生产成本。In the continuous chemical production process, when the electric centrifugal pump is used to send liquid, it is usually designed to use two electric centrifugal pumps of the same power in parallel, one is running and the other is standby. Due to the influence of various factors, the flow rate of the delivered liquid will change. When the flow rate becomes smaller, the power consumption of the electric centrifugal pump will not change, which will waste electric energy accordingly. With the development of science and technology, motor frequency conversion technology has appeared on the market, which has played a certain role in saving electric energy, but the motor frequency conversion technology is complicated and expensive, which is not conducive to saving production costs.
