How to judge the hydraulic failure of the hydraulic press

We buy back the hydraulic press, through a period of running-in period is more convenient to use, but there will still be some minor failures, so how do we distinguish these failures, only we distinguish, can be targeted to troubleshoot, then follow the small series together to learn to judge the hydraulic failure of the hydraulic press tips.

We can use the method of looking, hearing and asking to determine the cause of hydraulic failure, we can listen to the noise of hydraulic pump and hydraulic system of hydraulic press, whether the control elements such as relief valve and sequence valve have screams, listen to the impact sound of hydraulic cylinder reversing of hydraulic press table, whether the piston has the sound of impacting the bottom of the cylinder, whether the reversing valve has the phenomenon of colliding end cap, etc., pay attention to the abnormal sound of steam turbidity and trapped oil, and pay attention to the sound of the end cap. Check whether the hydraulic pump suction air, whether there is a serious trapped oil phenomenon, should be eliminated in time, hydraulic pump operation whether there is a knock caused by damage, not artificial knock, is the machine abnormal collision.

Use your hand to touch the moving parts of the hydraulic press, touch the surface of the hydraulic pump and the oil tank to see if you feel hot, if you have to check the reason for the high temperature rise, touch the vibration of the moving parts and pipelines of the hydraulic press, if there is high frequency vibration to check the cause of its production.

To determine whether the oil of the hydraulic press has deteriorated and become smelly, whether the rubber parts have a burnt taste because of excessive heat, etc., the general failure of the hydraulic press will be recorded, then we must regularly go to see the fault analysis, repair and inspection handover records, maintenance and maintenance. And everyone's judgment ability is different, the results are different, but as long as the fault can be eliminated is better, but still want to find technicians to repair is the best.
