机械效率,对液压泵是指其理论转矩与实际输入转矩的比值。对液压马达其实际输出的转矩为理论转矩克服摩擦力后的转矩,因此其机械效率为实际输出转矩与理论转矩的比值。CFM模组通常被放置在引擎罩下面,它们比那些可在乘客舱里发现的部件经历了更加极端的温度变化。这种热应力可加速功率场效应管的疲损和导致早期故障。汽车发动机罩下面的部件也可能被暴露于流体攻击之下,从而导致被腐蚀和在印制电路板形成局部热点。通常情况下,CFM模组并不包括一个微型控制器,后者可以在一定条件下被用来板上诊断和自动触发功率场效应管断开信号。通过软件方法来阻止功率场效应管故障是无法使用的,因此二级电路保护变得必要,从而使热失控不会引起危险的热事件。以下常规泵型号VA1-08FA3,VA1-08FA2,VA1-08FA1VA1-12FA3,VA1-12FA2,VA1-12FA1VA1-15FA3,VA1-15FA2,VA1-15FA1VA1-12FA3,VB1-20FA3,VB1-20FA2VB1-20FA1,VB1-24FA3,VB1-24FA2VB1-24FA1,VC1-26FA3,VC1-26FA2VC1-26FA1,VB1-24FA3,VD1-25FA3VD1-25FA2,VD1-25FA1,VD1-30FA3VD1-30FA2,VD1-30FA1,VE1-35FA3VE1-35FA2,VE1-35FA1,VE1-40FA3VE1-40FA2,VE1-40FA1,VE1-45FA3VE1-45FA2,VE1-45FA1,VE1-40FA3VA1A1-0808F-A1,VA1A1-0808F-A2VA1A1-0808F-A3,VA1A1-1212F-A1VA1A1-1212F-A2,VA1A1-1212F-A3VA1A1-1515F-A1,VA1A1-1515F-A2VA1A1-1515F-A3,VB1B1-2020F-A1VB1B1-2020F-A2,VB1B1-2020F-A3VB1B1-2424F-A1,VB1B1-2424F-A2VB1B1-2424F-A3,VD1D1-2525F-A1VD1D1-2525F-A2,VD1D1-2525F-A3VD1D1-3030F-A1,VD1D1-3030F-A2VD1D1-3030F-A3,VE1E1-4040F-A1VE1E1-4040F-A2,VE1E1-4040F-A3VE1E1-4545F-A1,VE1E1-4545F-A2VE1E1-4545F-A3
