Energy-saving features of permanent magnet variable frequency screw machine:

1, suitable for non-full load uninterrupted gas supply conditions. Assumed working condition: a 6 m2/min screw machine supplies several gas consumption equipment (or multiple gas consumption points on a device, the machine load reaches 90% when high gas consumption, the average gas consumption is 70%, the low gas consumption is 20%, such working condition is very suitable for the selection of 37 kw permanent magnet frequency conversion screw machine, it is about 26% energy saving than 37 kw power frequency machine; Working condition 2: a 6 m2/min screw machine supplies air to a device whose gas consumption exceeds 5.5m/min, and the load rate is always over 90%. Therefore, 37 kw power frequency machine is selected to reduce the purchase cost.

2. Permanent magnet frequency conversion screw machine adopts high efficiency permanent magnet synchronous motor, which has better energy saving performance compared with ordinary high efficiency motor. Especially in low speed operation, it can still maintain high motor efficiency; Frequency converter can be adjusted according to air consumption, frequency conversion range can be from 5% to 100%, ordinary frequency conversion is from 50% to 100%. Therefore, it is more energy efficient than ordinary inverter 10%-15%, is the upgrade product of ordinary inverter screw machine.

3. The power frequency machine must set a pressure difference of 1-1. 5bar to ensure the normal operation of the gas equipment. The permanent magnet variable frequency screw machine can directly reach the pressure required by the gas equipment (considering the pipeline pressure drop, increase about 10% appropriately), and the exhaust pressure will reduce the power consumption and achieve the purpose of saving electricity. The pressure difference of 1-1. 5bar will waste 10%-15% of the electric energy.

4. The permanent magnet frequency conversion screw machine is started soft, the current will not exceed the rated current, and it will not cause current shock to the power grid and electrical equipment, and there is no energy waste.

* not all working conditions are suitable for permanent magnet frequency conversion screw machine, so general said permanent magnet frequency conversion than power saving frequency machine is wrong!
