How to solve the problem of the hydraulic system of YAW-3000B full automatic pressure testing machine
Aiming at the problem of inadequate amount of oil YAW-3000B automatic pressure testing machine hydraulic system. First we analyze the cause of the problems, then according to the reasons to take different measures, by our technical staff analysis, probably due to the following two points
First, the overflow valve automatic pressure tester for hydraulic YAW-3000B appears fault, or is a slide valve card in the open position, produced a large amount of leakage;
Second, oil suction pipe and other binding surface is not tight, causing air mixed with the hydraulic pressure test machine within the pump.
For these two reasons, we can take the following measures:
First, remove the overflow valve check valve and cleaning, YAW-3000B automatic pressure test machine to overcome internal leakage.
Second, check and tighten the pipe joint of the oil suction pipe, and the sealing performance of the hydraulic system of the hydraulic YAW-3000B full automatic pressure testing machine.
