The main reasons for the lack of pressure in the four-column hydraulic press
During the operation of the four-column hydraulic press, the system pressure suddenly drops to zero and cannot be adjusted. In most cases, it is the problem of the pressure regulating system itself. The reasons should be found from the following aspects: whether the damping hole of the relief valve is blocked; there is foreign matter on the sealing end of the relief valve; the main core valve of the relief valve is stuck in the open position; the electromagnet of the unloading reversing valve is burned It is damaged, the wire is broken or the electrical signal is not sent; for the proportional relief valve, it may also be the reason for the interruption of the electrical control signal.
When the four-column hydraulic press is restarted after being stopped for a period of time, the pressure is zero. The possible reasons are that the relief valve is rusted in the open position; the hydraulic pump motor is reversed; the hydraulic pump is not sucked up due to the blockage of the filter or the leakage of the oil suction pipe Oil.
When the four-column hydraulic press is installed, dismantled and replaced by the maintenance components, the possible reasons for the phenomenon of zero pressure are as follows: the hydraulic pump is not installed tightly, and the working volume cannot be formed; the hydraulic pump is not filled with oil, and the sealing oil film cannot be formed; the reversing valve core is installed reversely, The reversing valve is installed reversely. If there is a U-shaped reversing valve in the system, once it is installed reversely, the system will be depressurized.
The above is the analysis of several situations of the four-column hydraulic press system when there is no pressure and the solutions on how to deal with various situations. I hope it can be helpful to you. This article is from the official website of the manufacturer WORLD Press Machine www.pressmachine-world.com, please indicate the source for reprinting!

The four-column hydraulic press is also called the four-column press. The abnormal pressure of the four-column hydraulic press is a common fault. There are three main points: the system has no pressure, the pressure is not adjustable, and the pressure fluctuates and is unstable. So today, we will focus on the main reasons and solutions that cause the four-column hydraulic press to have no pressure.
