Frequency conversion screw air compressor

How much can be saved?

The energy consumption of producing compressed air may exceed 40% of the company's total energy consumption, which can significantly reduce energy consumption. The VS (Variable Speed Drive) compressor can adjust the gas output according to the actual gas consumption, thereby reducing additional energy consumption by 25-44%.

The frequency conversion machine reduces energy consumption through the following points

Eliminate the inefficient conversion process from full load to unloaded.

Compared with ordinary inverters produced by other manufacturers, permanent magnet PM motors can save 6-7% energy. Built-in one-piece shaft direct connection structure.

Avoid unloading power consumption.

Maintain the pressure band of the pipe network within 0.01MPa.

Reduce average work pressure.

Reduce system leakage.

The soft-start feature increases the current balance of the motor to avoid current impact.

Provides free choice of pressure from 4 to 13 bar, which can reduce energy consumption.

One-piece shaft structure permanent magnet motor: stable operation

The permanent magnet motor and the compressor main body adopt the built-in integral shaft direct connection structure.

There is no mechanical loss caused by belts and gears, and the mechanical loss is completely reduced, and the structure is more compact.

The permanent magnet (PM) motor has no motor bearing, which eliminates the fault point of the motor bearing and has high transmission efficiency.

Permanent magnet motor adopts ammonium iron boron permanent magnet 120 degrees without loss of magnetism and long service life. The stator coil adopts the special corona resistant enameled wire of the frequency converter, which has good insulation performance and longer service life.

Permanent magnet motor frequency conversion control

The frequency conversion control can adjust the number of revolutions according to the required air volume. Compared with non-inverter machines that cannot control the number of revolutions, the energy-saving effect is more obvious.

Equipped with a permanent magnet (PM) motor, it saves about 6-7% energy compared with general-purpose inverters. Especially in the low load area, the outstanding control range and structure give play to obvious energy-saving advantages.

The permanent magnet (PM) variable frequency air compressor, which can exert energy efficiency in a wide range, saves about 42% of energy compared with ordinary industrial frequency air compressors.
