Reasons for the lack of oil in the 100-ton four-column hydraulic press and solutions

Reasons for the lack of oil in the 100-ton four-column hydraulic press and solutions:

1. 1. The oil suction pipe or oil filter of the 100-ton four-column hydraulic press is blocked.
2. 2. The oil viscosity is too high.
3. 3. The pump speed of the four-column hydraulic press is too high.
4. 4. The end gap or circumferential gap is too large.
5. 5. The overflow valve is faulty.

The key problems of these five issues are poor oil absorption of the four-column hydraulic press, serious leakage, and bypass return oil.

Solution: The oil filter of the 100-ton four-column hydraulic press should be cleaned regularly, and the oil flow should be twice the pump flow. Oil viscosity, pump speed, should choose the oil absorption height according to the regulations. In addition, check the gap between the pumps of the four-column hydraulic press and repair components such as safety valves.
