What are the precautions for the use of hydraulic system?
(1) The operator must be familiar with the operating essentials of the hydraulic component control mechanism; familiar with the relationship between the rotation direction of the hydraulic component adjustment knob and the pressure and flow changes, etc., to prevent accidents caused by adjustment errors.
(2) Check the oil temperature before starting the pump. If the oil temperature is lower than 10℃, it should be operated without load for more than 20 minutes before loading operation. If the room temperature is below 0°C or higher than 35°C, heating or cooling measures should be taken before starting. Pay attention to the oil temperature rise at all times during work. During normal operation, the temperature of the oil in the oil tank of the general hydraulic system should not exceed 60°C; the temperature of the oil in the hydraulic system or high-pressure system oil tank of the program-controlled machine tool should not exceed 50°C; the temperature rise of the precision machine tool should be controlled below 15°C.
(3) The hydraulic oil should be checked and replaced regularly. For newly put into use hydraulic equipment, the oil tank should be cleaned and replaced with new oil after about 3 months of use. In the future, cleaning and oil change shall be carried out every six months or a year according to the requirements of the equipment manual.
(4) Pay attention to the working conditions of the filter during use, and the filter element should be cleaned or replaced regularly.
(5) If the equipment is not used for a long time, all adjustment knobs should be loosened to prevent permanent deformation of the spring and affect the performance of the component.
