(2) Before starting the pump, the oil temperature should be checked. If the oil temperature is below 10 ℃, it should be run without load for more than 20 minutes before loading and running. If the room temperature is below 0 ℃ or above 35 ℃, heating or cooling measures should be taken before starting. Pay attention to the temperature rise of the oil at all times during work. During normal operation, the temperature of the oil in the hydraulic system oil tank should not exceed 60 ℃; The oil temperature in the hydraulic system or high-pressure system oil tank of the program controlled machine tool should not exceed 50 ℃; The temperature rise of precision machine tools should be controlled below 15 ℃.
