Product/Service Description
The fan is a machine that compresses and transports air. The lower the pressure of the air is called the fan, the larger is the blower. The types of blowers are: centrifugal fan, mixed flow fan, axial fan...etc. The fan is the most widely used, but due to the long start-up time, the starting current is large, about 6 to 8 times the rated current, the mechanical impact on the motor and the fan is large, which affects the service life of the fan. The mechanical characteristics are very similar to the pump However, the no-load torque of the fan is much smaller than that of the pump, so when running at low speed, the energy-saving space will be larger than that of the pump. If the frequency conversion energy-saving module can be used to improve, reduce energy consumption and increase production efficiency. An effective way of product price competitiveness.
The characteristics of the fan will change with the speed. Because the fan is a quadratic load, the electric power consumed is proportional to the cube of the speed. The frequency conversion energy-saving module is used for speed regulation. It has built-in advanced power electronic devices IGBT and multi-level topology. The circuit and sine wave PWM vector control strategy can be controlled by the processor to generate a high-voltage AC system with adjustable frequency and current dependent on the load after power conversion of a fixed frequency and three-phase AC power system, which can Realize continuous speed regulation and reduce energy consumption.
