Computer control 30T cement pressure tester (fault phenomenon, cause and elimination method) 1, Pipe fittings at the leakage of oil One of the reasons is that the sealing connection is loose, in which case the components should be properly assembled and tightened, the second reason is the seal damage, in this case the seal should be replaced with seals such as 0 seals, combination washers or clamp, when replacing seals with kerosene cleaning seals and fittings to prevent contaminants from entering the hydraulic system, damaging hydraulic components (Such as commutator valve, proportional valve). 2. Test Power Overshoot The most important reason for the test force overshoot is that the control parameters are not accurate, first of all, we should consider whether the test force rise speed is correct, if not correct should modify the test force rise speed, and then see if the PID has been adjusted, if there is no should adjust the value of the PID. 3, The pressur...
