目前服务于各港口的大功率与中小功率的拖轮,它们的副柴油机大部分采用了气动马达来起动。用气动马达来起动主副柴油机,利用了通常的机舱压缩空气,简化了柴油机起动系统的复杂性,维护管理方便,尤其用在副柴油机的起动,要比电起动的可靠性好得多。但气动马达在北方的冬季,由于润滑油的使用不当,容易造成转子叶片的粘 Currently serving the high-power and low-power tugboats in all seaports, most of their sub-diesels are powered by air motors. The use of air motor to start the main diesel engine, the use of the usual compressed air cabin, simplifying the complexity of the diesel engine starting system, easy maintenance and management, especially in the auxiliary diesel engine start than the reliability of electric start much better. But the air motor in the winter in the north, due to the improper use of lubricating oil, likely to cause sticky rotor blades
