The movement of the four-column press is mainly realized by the circulation of hydraulic oil, and the oil leakage of the machine often occurs when we use it normally, which brings great trouble to our work. For the oil leakage of the press, the main points are as follows:

1. The seal is damaged. The presses we use basically connect the machine body and the hydraulic system into a loop through oil pipes, and seals will be installed at each connection port of the machine to ensure that the oil pipes do not leak oil, due to long-term use , The seal is damaged by the impact and corrosion of hydraulic oil, which leads to oil leakage in the oil circuit.
2. The valve body leaks oil. The solenoid valve is the heart of the four-column press. It mainly depends on different solenoid valves to achieve diversification of actions. If the seals in the solenoid valve are installed improperly, the seals will be damaged and the valve body will leak oil. Happening.
3. Connect the pipeline. The connecting pipelines between the hydraulic systems are all welded, and the occurrence of trachoma during welding will lead to oil leakage in the pipeline later.
