利用高压检测系统对产品进行承压能力和密封性能检测时,在停机保压过程中,高压检测系统的供液端有时会内漏造成压力下降,导致检测结果错误。本文介绍了一种高压检测系统供液端与工作端进行分离的改进措施,在供液端与工作端中间加装一个电磁阀,在保压时将电磁阀关闭,从而将供液端与工作端分开,在停机保压时,在供液端系统内漏不会造成工作端的压力下降,因此在供液端内漏的情况下仍可以进行正常的稳压检测工作,工作效率成倍提高,这种改进思路,可以推广到其它高压检测压系统的改进或设计中。
The use of high-pressure detection system for product pressure capability and sealing performance testing, the shutdown packing process, the high-pressure detection system for the end sometimes leakage caused by pressure drop, resulting in the test results wrong. In this paper, an improved method for separating the liquid end from the working end is introduced in this paper. A solenoid valve is installed between the liquid supply end and the working end to close the electromagnetic valve during the pressure keeping, so that the liquid supply end and the work end End separation, when the pressure in the shutdown, the liquid end system leakage will not cause the end of the pressure drop, so the liquid supply end of the leak can still be normal voltage detection work, work efficiency increased exponentially, This idea of improvement can be extended to other high-pressure test pressure system improvements or design.
