What are the important functions of the four-column hydraulic machine cooler

1. The cooler is installed at the overflow port of the main relief valve. The characteristics of this installation method are that the hot oil generated by the relief valve is cooled directly and is not affected by the impact pressure of the system. The one-way valve plays a protective role and the stop valve allows the hydraulic oil to return directly to the tank when starting. .

2. The cooling unit is installed on the main oil return line. The characteristics of this installation method are that the cooler is directly installed on the main oil return line, and the cooling speed is fast. However, when there is impact pressure in the system circuit, 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 hydraulic shock.

In addition, users are reminded that when choosing a four-column hydraulic machine cooler, they should choose a cooler with good heat dissipation effect, sufficient strength, frame-type four-column hydraulic machine, and easy control of the oil to maintain a constant temperature, so that it can better dissipate heat.
