When the single-column hydraulic press is in operation, it is also common for the hydraulic system to not maintain pressure. The four-column three-beam hydraulic press will start to work after the pressure rises, and the pressure will drop. The reasons for this situation are as follows:
1. The main relief valve in the hydraulic system of the single-column hydraulic press is seriously worn, resulting in overflow and debris, which are stuck, so the pressure cannot rise;
2. The flushing valve on the upper part of the oil cylinder is not opened, so it cannot rise normally;
3. The pump flow is abnormal. If the pump flow and pressure become inversely proportional, it will also cause the hydraulic pressure to fail to rise;
4. The direction valve of the lower chamber of the hydraulic system is stuck, and the same oil also enters the upper and lower chambers;
5. Defects in the circuit will also cause the hydraulic pressure to fail to rise. Use a screwdriver to poke the small reversing valve to see if it is stuck, and then test whether the indicator light of the rising small valve is on;
6. The spool of the filling valve of the hydraulic system is stuck due to debris or springs, which will also cause the hydraulic pressure to fail to rise;
7. The cartridge valve and reversing valve in the hydraulic system are stuck;
8. Whether the pressure of the hydraulic system of the single-column hydraulic press is normal, whether the cylinder is defective, etc. will cause the hydraulic pressure to fail to rise normally.
