Causes of high-energy pump motor is running normally direct start or Y / D start, starting current equal to 4-7 times the rated current, which requires not only high network capacity, energy-efficient water pump manufacturer in Jiangsu, and equipment and the grid will start serious impact, affecting life. After using an inverter device using the frequency of the current soft-start function will start from scratch, saving water pump manufacturers, does not exceed the maximum rated current, reducing the impact on power and power capacity requirements, to extend the use of the equipment life. Frequency Reactive power saving technology will not only increase the heat line losses and equipment, energy-saving pump manufacturers in Hebei, the main thing is to reduce the power factor of the grid leads to lower active power, power factor correction saving large amount of reactive power consumption in line among , the device uses inefficient, wasteful, by the formula P = S╳COSФ, Henan saving water pump manufacturer, Q = S╳SINФ, where the apparent power S-, P- active power saving pump manufacturers, pump manufacturers in Jiangsu energy efficiency, Chen poly Energy (certified merchants) are provided by Shandong morning Poly Energy Technology Services Co., Ltd.
