Common problems and troubleshooting solutions of oil press

Oil presses are essential machines for extracting oil from crops. However, like any other machine, they are not immune to problems. As a user, it is important to identify the cause of the problem before attempting to solve it.

Common problems and troubleshooting methods encountered in the use of oil press

1, Low pressure in the screw oil press

Regular maintenance is crucial to ensure the proper functioning of an oil press. One of the most common problems encountered is low pressure in the screw oil press. This can be caused by a blocked oil discharge valve or wear and tear on the piston of the oil pump and pump body. To solve this problem, the oil net can be removed and washed or the cup can be replaced. If the problem persists, replacing the oil pump piston and the pump body may be necessary.

2, Relief valve failure

Another common problem is relief valve failure. This can be caused by debris in the oil that prevents the steel ball and valve from closing or a spring that has lost its flexibility. Loose pressure regulating screws can also cause the valve to jump without reaching the expected pressure, leading to regular overpressure jump valve and damage to the steel ball or valve. To solve this problem, the relief valve should be removed and washed to remove any impurities. The spring of the relief valve should be replaced in a timely manner, and the pressure regulating screw should be adjusted to ensure that the safety valve jump valve jumps when the pressure reaches its limit. Grinding the valve can also help avoid overpressure jump valve during operation.

3, Pump failure to absorb oil

If the pump of an oil press cannot absorb oil, it is usually due to impurities in the oil blocking the filter, oil tubing, or nozzle. This results in a lack of oil in the oil tank and a failure of the filling valve. To solve this problem, the filter, oil pipe, and nozzle should be removed and washed, and the fuel tank should be oiled. The piston of the oil pump should be pulled out, and oil should be filled to exhaust any air. The steel balls, spring, or nozzle of the filling valve should be repaired or replaced to ensure that the valve seals well and does not leak oil.

4, Excessive slag leakage during the oil pressing process

Excessive slag leakage during the oil pressing process is another problem that can occur. While a small amount of slag leakage is normal, excessive leakage is not. This can be caused by a cake that is too thin, poor plasticity of oil plants, or too large a clearance of the pressing bar or bending of an individual pressing bar. To solve this problem, the thickness of the cake should be adjusted according to the specifications. Adding an appropriate amount of water and running the machine to increase the temperature of the screw oil press can improve the plasticity of oil plants. If the clearance of the pressing bar is too large, it should be adjusted in a timely manner. If the pressing bar bends, it should be removed and straightened through grinding or sizing block before being reinstalled.

While problems are inevitable when using oil presses, they can be easily solved with proper maintenance and troubleshooting techniques. If you encounter a problem that is not covered in this article, do not hesitate to contact us for further assistance.
