1. The hydraulic press cooler is installed at the overflow port of the main overflow valve. The characteristics of this installation method are: the hot oil generated by the relief valve is directly or cooled, and it is not affected by the impact pressure of the system, the one-way valve plays a protective role, and the stop valve can directly return the hydraulic oil to the oil tank when it is started.
2. The cooling is installed on the main oil return road. The characteristics of this installation method are: the cooler is directly installed on the main oil return road, and the cooling speed is fast, but when the system circuit has an impact pressure, the cooler is required to withstand higher pressure.
3. Independent cooling circuit. The advantage of an independent cooling circuit is that; a separate hydraulic pump passes the hot working medium to the cooler, which is not affected by hydraulic shocks.
Large equipment or hydraulic systems with serious heat generation are usually equipped with a separate cooling system, and the cooler is the core component of the cooling system. The main function of the cooler is to maintain the heat balance of the hydraulic system and keep its system temperature within the specified range. Generally, the temperature range is 35℃-55℃. When the temperature is higher than 55℃, the cooler will start. Cool down the oil temperature. Hydraulic equipment used in southern my country generally requires a cooling system, otherwise the equipment will be damaged due to excessive temperature in summer.
