Treatment method for high oil temperature of single-column hydraulic pressure

1) The volume of the single-column hydraulic oil tank is too small, the heat dissipation area is not enough, the oil cooling device is not installed, or the capacity of the cooling device is too small.

2) The quantitative pump oil supply system that selects the oil pump capacity according to the fast-forward speed will cause a large part of the excess flow to overflow from the relief valve under high pressure during operation, causing fever.

3) There is an error in the unloading circuit in the system or because the unloading circuit is not set up, the oil pump cannot be unloaded during intermittent operation, and the full flow of the pump overflows under high pressure, resulting in overflow loss and falling and fever, causing oil. fever.

4) The pipeline of the single-column hydraulic press system is too long, the circuit is excessive, and the partial pressure loss and the pressure loss along the process are greatly reduced.

5) Insufficient component precision and poor assembly quality, the mechanical friction loss between the relative activities is greatly reduced.

6) The joint gap of the joint parts is too small, or the gap is too large after application wear, and the internal and external leakage is large, resulting in a large volume loss, such as a decrease in the volume efficiency of the pump and a rapid fever.

7) The working pressure of the hydraulic system is adjusted higher than the actual need. Sometimes it is because the seal is too tight, or because the seal is broken and destroyed, and the leakage increases, it is impossible to adjust the pressure without increasing the pressure.

8) The weather and the operating conditions of the single-column hydraulic press are high in temperature, resulting in a drop in oil temperature.

9) The viscosity of the oil is improperly selected. If the viscosity is large, the viscous resistance will be large. If the viscosity is too small, the leakage will increase. Both conditions can cause the oil to heat up. This article is from the official website of the manufacturer WORLD Press Machine www.pressmachine-world.com, please indicate the source for reprinting!
