How to tell whether the filter press is running normally from the oil pressure state?

There is no oil in the fuel tank. Considering the transportation and other issues, the hydraulic oil in the fuel tank must be emptied when the new machine leaves the factory. How can there be pressure without oil? The editor of Donglong Chemical Machinery will explain the lower plate and frame filter press oil pump for you. Normal working oil pressure.

1. The hydraulic oil is not added enough, resulting in no oil absorption, and the hydraulic oil should be added according to the position indicated by the liquid level gauge.

2. The adjustment position of the upper limit pointer of the electric contact pressure gauge is low, adjust it to the appropriate position, and adjust the relief valve to make it reach the desired pressure.

3. The relief valve adjustment pressure is low, loosen the relief valve lock nut, rotate the relief valve handle (rotate inward to increase the oil pressure, rotate outward to reduce the oil pressure) to adjust the oil pressure, and the ordinary pressure gauge model is adjusted to the rated value Working pressure, the electric contact pressure gauge model is adjusted to be slightly higher than the rated working pressure.

4. After years of use (3-5 years) of the filter press, the sealing ring installed on the piston in the oil cylinder is worn, and the pressure will not rise.

5. If there is oil leakage on the oil road, the pressure will not go up.
