Application
The energy saving of frequency converter is mainly reflected in the application of fan and water pump. In order to ensure the reliability of production, all kinds of production machinery in the design of power drive, have a certain amount of surplus. When the motor can not run at full load, in addition to meet the power driving requirements, the excess torque increases the consumption of active power, resulting in the waste of electric energy. The traditional speed regulation method for fans, pumps and other equipment is to adjust the air and water supply by adjusting the baffle and valve opening at the entrance or exit. The input power is large, and a lot of energy is consumed in the cut-off process of the baffle and valve. When frequency control is used, if the flow requirement is reduced, the speed of the pump or fan can be reduced to meet the requirements.
Reactive power not only increases the line loss and equipment heating, more importantly, the reduction of power factor leads to the reduction of power grid active power, a large number of reactive energy consumption in the line, equipment use efficiency is low, serious waste, the use of variable frequency speed regulating device, due to the role of the frequency converter internal filtering capacitance, thereby reducing reactive power loss, increase the active power grid.

FAQ
Q: Do you supply pattern ? Is it free?
A: If the pattern is low value, we will grant the free pattern with freight collect. But for some excessive fee samples, we want to gather the pattern charge.
Q: What is your time period of payment?
A: 30% down charge earlier than producing and 70% stability charge earlier than shipping.
