摘　　要：一般来说,液压泵出厂试验、型式试验及寿命试验使用的试验设备,其驱动功率是由被试泵所能产生和达到的功率所决定的。在进行试验项目测试时,泵所产生的压力能不是来做功,而是要经过节流或溢流加载的方式转换成热能或其他形式来把它消耗掉。在液压试验台的设计和制造中,能否对这部分能量进行回收和利用,而不是任其被动消耗,这是该文要讨论和解决的问题。As a rule, The test equipment which be used in hydraulic pump＇s factory test, type test and life test, It＇s driving power is determined by the peak energy of tested Pump. In test run, the pump＇s pressure energy is not for working, but for transforming into heat energy or other forms by throttling or overflow loading. There is a problem in design and fabrication of hydraulic pump test-bedthat is whether this part of the energy can be reclaimed and reused rather than consumed passively. This paper will discuss and solve this problem.
