What is the reason for insufficient pressure in the hydraulic press?
If insufficient pressure occurs during the operation of the hydraulic press, it may be caused by low efficiency or excessive leakage, damage or blockage of the overflow valve, too little hydraulic oil, blockage of the oil inlet pipe or oil filter, severe wear or damage of the hydraulic pump, etc. During maintenance, the oil level, inlet and outlet oil pipes, inlet and outlet pressure valves, oil pipes or filters should be checked in turn to find the problem and repair it. The hydraulic press uses liquid as the working medium, and hydraulic oil is generally used, so it is also called an oil press. In the process of using the hydraulic press, sometimes insufficient pressure is encountered.
What is the main reason?
The efficiency is too low or the leakage is too large, and the pressure oil restored by the pump itself is not enough to maintain the normal operation of the system
The overflow valve is damaged or blocked, so that the normal pressure supplied by the hydraulic pump leaks here, or cannot be adjusted
The amount of hydraulic oil in the hydraulic press tank is insufficient, and the system is sucked empty.
The hydraulic system of the four-column hydraulic press leaks and leaks oil
The oil inlet pipe or oil filter is clogged
The hydraulic pump is seriously worn or damaged
How to repair the oil press if the oil pressure is insufficient?
1. Check the oil level first. If the oil level is lower than the lowest scale, add oil.
2. If the oil level is normal, check whether the inlet and outlet pipes are leaking. If there is oil leakage, they should be repaired or replaced.
3. If the inlet and outlet pipes are well sealed, check the working condition of the inlet and outlet pressure valves. If the inlet and outlet pressure valves cannot be closed, they should be removed to check whether there are cracks or scratches on the parts, whether the oil circuit and oil hole are unobstructed, and whether the spring stiffness is reduced. If problems are found, they should be solved in time.
4. If the pressure valve is normal, the oil press should remove the oil pipe or filter for inspection. If there is any blockage, it should be cleaned and the sediment should be removed.
5. If the oil pipe is unobstructed, check the hydraulic pump and replace it if necessary.
6. If the hydraulic oil foams, check the installation of the return pipe. If the oil level of the return pipe is lower than the oil level of the tank, reinstall the pipe.
How to avoid insufficient pressure in a four-column hydraulic press?
The following three aspects need to be achieved
1. Ensure that the oil pump can smoothly discharge oil and have a suitable oil output, and have sufficient pressure to maintain the normal operation of the system
2. Ensure that the overflow valve can be used normally to avoid problems such as blockage and damage
3. Ensure that there is enough oil in the tank to avoid problems such as a vacuum in the system
