The cooling fan system cooled the hydraulic oil through the radiator when the oil returned from the hydraulic pump is directly directed to the closed cooling fan. This device is characterized by high durability, and because the oil pressure returned from the hydraulic pump is very high, is equipped with a safety valve works efficiently to protect the system from damage caused by high pressure.
In general, the temperature of the hydraulic oil should be controlled within the range 30-50,, in order to reduce the heat of the hydraulic parts of the high pressure system. Frequent check and replacement of the refrigerant every 6 months helps ensure high efficiency and constant use of the pump. This system has a low power consumption of 400 watts, thus ensuring low operating cost.
