Hydraulic presses are built to exacting standards and are designed to withstand the tremendous pressures experienced during ordinary operation, and despite this, these powerful and versatile machines are not immune to the occasional mechanical accident, and even the best-maintained hydraulic presses can fail, often for reasons that cannot be immediately seen. This articleZhongyou Heavy IndustryBring the repair and diagnosis of two common fault problems of hydraulic press.
In this case, seeking professional hydraulic equipment repair services is always the safest and most effective choice, because these services are equipped with all the tools and knowledge needed to quickly diagnose and correct mechanical hydraulic machine problems. However, you can speed up the repair process by trying to find the cause of the problem yourself-these are the two most common problems encountered by hydraulic presses and the most likely cause.
1. hydraulic machine overheating:
The huge pressure and friction generated by the hydraulic machine during standard operation generates a large amount of waste heat, which must be effectively dissipated to prevent damage to the hydraulic cylinder and system.
Many problems may cause the hydraulic press to overheat, but the most common cause is the hydraulic press overheating, usually related to the hydraulic oil used by the hydraulic press to transmit pressure. If this fluid is contaminated, or degraded due to aging, it will lose its thermal conductivity, which will increase the operating temperature of the hydraulic machine. Changing the oil and cleaning (or replacing) the filter in the oil reservoir of the hydraulic machine may be a quick and relatively simple way to solve the overheating problem.
If the oil supply to the hydraulic machine is not the source of the overheating problem, there may be a problem with the heat exchanger. If air-cooled heat exchangers suffer physical damage or become clogged with dust and debris, their efficiency will be reduced, and water-cooled heat exchangers usually fail due to leakage. Check the heat exchanger of the hydraulic press for obvious problems, and ask professional maintenance service personnel to deal with the simplest problems.
2. slow pressure build-up:
When the hydraulic press is activated, the hydraulic punch will drive the hydraulic press to reach its required pressure rating within a second or two, and you may need to worry about the slower pressing speed of the punch. In most cases, the hydraulic pressure that slowly reaches the optimal pressure will cause the fluid pump to fail, and the hydraulic oil does not flow into the plunger quickly enough to increase the pressure quickly.
There may be many reasons for the pump problem, but you should first check the leakage between the pump and the hydraulic press to prevent a large amount of fluid from entering the cylinder. Inclusion of dirt and solids in the fluid line between the pump and the hydraulic press can also cause slow pressurization. You should also check the pump itself, because the motor that powers it is rated for a limited number of revolutions, and if they are too old, they may not work properly.
