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。 Design a remote pressure relief device for large flow emulsion pump (400 L / min) and apply it to hydraulic support inspection. Solve the problem that the pump can only be manually regulated in place at the moment. In the hydraulic support testing and inspection, due to the different test pressure of the jack and each part of the jack, it is necessary to adjust the pressure of the pump frequently. At present, only manual local pressure regulation is available, the efficiency is extremely low, and the pressure regulation accuracy is difficult to meet the requirement of the measurement and control system , Severely restricting the progress of testing technology.
