The reason why the single-column hydraulic press has no pressure or low pressure

The reason why the single-column hydraulic press has no pressure or low pressure

1. Check whether the oil in the hydraulic oil tank is satisfactory. If the oil in the oil tank is too small, it will cause the system to be emptied;

2. Investigate whether there is a leak in the fuel tank. After the hydraulic press is used for a long time, the hydraulic equipment will age, which may cause the leakage of the fuel tank;

3. Whether the leakage of the oil pump of the single-column hydraulic press is too large, the hydraulic pressure itself cannot be used, and the pressure cannot maintain the normal operation of the system;

4. Air leakage at the oil inlet end of the oil pump will also result in a lack of oil pumping capacity and insufficient pressure;

5. Check whether the oil has entered the cavity of both ends together;

6. The opening of the relief valve is stuck, the load is too large, the dispatching pressure of the relief valve reaches the maximum peak value, and the hydraulic cylinder cannot get pressure to do work.
