压力表开关在整个液压系统中因工作原理及结构均较为简单,其质量对系统的影响往往易被忽视,我们通过近几年的摸索与实践发现,压力表开关质量的低劣,轻则会使系统压力损失加大,测压不准,重则导致控制阀失灵,甚至使系统压力升不上去。其设计原埋、制造方法等固然是重要因素,但关键却在于如何把好《出厂试验》这道关。一、压力表开关弊病的产生
Pressure gauge switch in the entire hydraulic system due to the working principle and structure are relatively simple, the quality of their impact on the system is often easily overlooked, through our exploration and practice in recent years found that the poor quality of the pressure gauge switch, ranging from light Increased system pressure loss, pressure measurement is not allowed, it will lead to failure of the control valve, or even make the system up pressure. The design of the original buried, manufacturing methods, of course, is an important factor, but the key lies in how to make a good “factory test” this pass. First, the pressure gauge switch ills
