The related factors causing the leakage of the four-pillar hydraulic press system are as follows:

1. Work pressure

Under the same conditions, the higher the pressure of the four-pillar hydraulic press system, the greater the possibility of leakage, so the size of the system pressure should be in line with the best value needed by the hydraulic system.

2. Working temperature

Most of the energy lost by the hydraulic system is converted into heat energy. Some of this heat energy is released into the atmosphere through the surface of the hydraulic components themselves, pipelines, and oil tanks, and the rest is stored in the hydraulic oil, which will make the oil temperature rise.

3. Cleaning procedure of oil

The hydraulic oil of the four-pillar hydraulic press often contains various impurities. The impurities in the hydraulic oil will aggravate the wear on the surface of the hydraulic components, the spool of the hydraulic valve is blocked, the hole is blocked, and the seal is damaged, which causes damage to the hydraulic valve and causes the leakage of hydraulic oil.

4. Selection of sealing device

The correct selection of sealing device is very important to prevent leakage of the four-pillar hydraulic press system. Reasonable selection of sealing devices can improve the performance and efficiency of the equipment, and prolong the service life of the sealing device, so as to effectively prevent leakage.
