Installation position of hydraulic oil cooler
1. The oil cooler is generally installed on the return line of the hydraulic system or the overflow line of the overflow valve. The heating of the oil is due to a large amount of high-pressure oil flowing out of the overflow valve. At this time, the cooler should be installed on the drain line of the overflow valve. In this way, the temperature of the overheated oil is lowered before it returns to the tank. After the cooler is installed, the pressure loss is generally 0.01～0. lMPa. An example of the installation position of the cooler. The pressure oil output by the hydraulic pump directly enters the system, and the heated oil return and the oil overflowed by the overflow valve are cooled by the cooler 1 and then returned to the oil tank. The one-way valve 2 is used to protect the cooler. When the cooler is not needed, the shut-off valve 3 is opened to provide a passage.
Installation location of hydraulic oil cooler
2. The oil cooler should not be placed in front of the oil return filter. As the oil temperature decreases and the viscosity increases after passing through the cooler, the flow capacity of the filter will be weakened, so try to keep the cooler in the oil return After the filter, a separate cooling circuit can be used if necessary.
The oil cooler is installed on the overflow valve drain line and the oil return line of the hydraulic system, so that the temperature of the overheated oil is reduced before returning to the tank. After the oil cooler is installed, the pressure loss is generally 0.01 to 0.1MPa.
