摘　　要：本文论述了液力传动的基本概念,对滑阀真空泵使用V型带传动所存在的问题进行了分析,阐明了将液力传动应用在滑阀真空泵上以后,既可以充分利用电机的最大扭矩启动的特点,来改善泵的启动性能,尤其是低温状态下的启动,整个启动过程平稳柔和,可隔离扭振,减缓启动冲击和振动,有效防止机械磨损,延长设备使用寿命;又可以利用它的限矩功能,将泵的能耗控制在一个适当的范围内,降低配套电机的功率,具有显著优异的节能效果。This paper discusses the basic concept of hydraulic transmission, analyzes the problem of rotary piston vacuum pump with V belt transmission. It clarified that after applying hydraulic transmission in the rotary piston vacuum pump, the full advantage of the maximum torque of the motor starting can be used to improve the starting performance of the pump, especially in low temperature condition. The entire startup process is Smooth and soft, torsional vibration can be isolated, start shock .and vibration can also be slowed. The hydraulic transmission effectively prevented mechanical wear and prolonged the service life of equipment. Its limited moment function controlled pump energy consumption in an appropriate range, reduce the power of motor, with excellent energy saving effect.
