Because of the use of frequency converter, so that pump speed decreased, exports to reduce stress, a reduction of mechanical wear, reducing maintenance workload, extended equipment life.

由于变频器的使用，使泵转速下降，出口压力降低，减少了机械磨损，降低了维修工作量，延长了设备的使用寿命。

For example: decontamination and wear of iron, longer life, extended oil change on the removal of smoke, to improve the internal compression force, increase power and reduce fuel consumption.

例如：清除油污和磨损的铁粉，延长寿命，延长换油期去除黑烟，提高内部压缩力，增加动力，降低油耗等。
