摘　　要：设计一种用于大流量乳化液泵(400 L/min)的远程调压卸荷装置,并应用于液压支架检测检验。解决目前该泵只能就地手动调压的难题。在液压支架检测检验时,由于立柱及各部位的千斤顶试验压力不同,需频繁对泵源调压,目前只能进行手动就地调压,效率极低,且调压精度难以达到测控系统的要求,严重制约检测检验技术的进步。Designed a device for large flow emulsion pump（400 L/min） station adjusting press and unloading remotely, and applied it into power support testing. Solved the problem that this pump press just can be adjust by manual. The press of legs and rams were different when tested them, so it deeded to adjust pump station press frequently, however, the adjusting just can be operated by manual, the efficiency was very low, and the press accuracy was difficult to meet the requirements of test system, it constrained the progress of testing technology seriously.
