What should I do if the oil temperature of the single arm hydraulic pressure is too high

1. Always pay attention to maintaining the design oil quantity in the fuel tank. Generally, the height of the oil level is required to reach 80% of the height of the fuel tank, so as to meet the conditions that the fuel tank has sufficient heat dissipation area and the oil has sufficient circulating cooling conditions. When the new machine is filled with oil, the oil tank should be filled up. After a few minutes of starting and running, the oil will enter the pipeline and the oil cylinder, and the oil cloth will drop. Therefore, it is necessary to add some oil.

2. Design a fuel tank of sufficient size, and install a cooler if necessary. If the surrounding ambient temperature is too high, the system should be isolated from the outside world. Strictly control the temperature of the system within the range of 20-60°C, and should not exceed 70°C.

3. When changing the oil, pay attention not only to drain the old oil in the oil tank, but also to replace the old oil in the entire system pipeline and working circuit. When refueling, use a filter screen of 120 mesh or more, and add enough oil according to the regulations, so that the oil has sufficient circulating cooling conditions. The fuel tank should be well ventilated for heat dissipation.

4. The pipeline should be shortened as much as possible, and it should not be too slender and bent, so as to make the oil flow as smoothly as possible.

5. When the high-pressure oil overflows from the relief valve to the tank unnecessarily for a long time, the design should be improved, and the variable pump or the correct unloading method should be used.

6. Regularly clean and replace the filter. For the filter with blockage indication, it should be replaced according to the indication. The performance, structure and validity period of the filter element must meet the requirements of its use. In case of sudden failure caused by hydraulic oil pollution, be sure to filter or replace the oil used in the hydraulic system.

7. The hydraulic pump of the single-arm hydraulic press and the places where it is easy to leak should be sealed, and the connecting parts should be fastened to avoid volume loss and heat.

8. When the setting value of the pressure regulating valve is too high, reduce the working pressure to reduce unnecessary energy loss.

9. Ensure that the equipment is well ventilated. This article is from the official website of the manufacturer WORLD Press Machine www.pressmachine-world.com, please indicate the source for reprinting!
