How to deal with the heat of the hydraulic oil of the four-column hydraulic press

1. The volume of the four-column hydraulic oil tank of the automobile exhaust pipe is too small, resulting in insufficient heat dissipation area; improper installation of the cooling device or no oil cooling device will cause the oil to heat up.

2. When the quantitative pump oil supply system is working, most of the excess flow overflows from the overflow valve under high pressure, which causes the multi-function hydraulic oil to heat up.

3. The unloading circuit in the hydraulic system fails or because the unloading circuit is not set up, the oil pump cannot be unloaded when it stops working, and the entire flow of the pump overflows under high pressure, resulting in overflow loss and heat, resulting in oil heating.

4. Due to the large number of pipelines in the hydraulic system of the four-column hydraulic press of the automobile exhaust pipe, the pipeline is intricate, resulting in a large local pressure loss and a large pressure loss along the way.

5. The precision of the components is not enough and the assembly quality is poor, and the mechanical friction loss between the relative movements is large.

6. The fitting clearance of the fittings is too small, or the clearance is too large after use and wear, the internal and external leakage is large, and the volume loss is large, such as the reduction of the volumetric efficiency of the pump and the rapid heating.

7. The working pressure of the hydraulic system of the four-column hydraulic press of the automobile exhaust pipe is adjusted higher than the actual need, and the working environment temperature of the hydraulic system is too high, which will cause the oil temperature to rise.

8. Improper selection of oil, high viscosity will lead to large viscous resistance, too low viscosity will increase leakage, both of which can cause oil to heat up.
