Brief introduction to hydraulic machine cooler installation problem
- Oct 31, 2018 -

1. The hydraulic machine cooler is installed in the overflow port of the main relief valve. The characteristic of this installation method is that the hot oil generated by the relief valve is directly cooled or not affected by the impact pressure of the system, and the one-way valve is protected. In effect, the shut-off valve allows hydraulic fluid to be returned directly to the tank at start-up.

2. Cooling is installed on the main oil return road. The characteristic of this installation method is that the cooler is directly installed on the main oil returning road, and the cooling speed is fast. However, when the system circuit has impact pressure, the cooler is required to withstand higher pressure.

3. Independent cooling circuit, the advantage of the independent cooling circuit is that a separate hydraulic pump passes the hot working medium into the cooler, and the cooler is not affected by the hydraulic impact.
