In the process of operation, the hydraulic system must be familiar with the operation method of its hydraulic component control mechanism to a certain extent. To a certain extent, it is familiar with the relationship between the rotation direction and pressure of the adjustment knobs of each hydraulic component and the change of flow rate. Adjustment errors cause accidents.

    The pump of the hydraulic system needs to check the oil temperature effectively before starting. If the oil temperature is lower than 10 degrees, it should be operated for more than 20 minutes at no load to load the machine. If it is used, its room temperature is 0 °C. Below or above 35 ° C, the heating or cooling measures should be taken before starting.

    The hydraulic system needs to pay attention to the temperature rise of its oil during the working process. In normal operation, the temperature of the oil in the tank of the general hydraulic system cannot exceed 60 degrees, and the program controls the hydraulic system of the machine tool or The oil temperature in the high pressure system fuel tank should not exceed 50 °C; the temperature rise of precision machine tools should be controlled below 15 °C.

    The hydraulic oil of the hydraulic system needs to be inspected and replaced periodically during use. For the hydraulic equipment that is newly put into use during operation, the fuel tank should be cleaned to a certain extent for about 3 months, and the new oil should be replaced. In the future, the cleaning and oil change should be carried out every six months or one year according to the requirements of the equipment manual.

    The hydraulic system should pay attention to the working condition of the filter during use. The filter element should be cleaned or replaced regularly. If the equipment is not used for a long time, all the adjustment knobs should be relaxed to prevent the spring from being permanently deformed and affecting the performance of the component.

    The operation requirements of the hydraulic system main engine mainly refer to the connection between the main machine actions and the completion of certain automatic cycles during operation. The host may impose many requirements on the hydraulic system during operation, and the designer should understand the host. These requirements are analyzed based on the purpose, work process and overall layout.

    The hydraulic system refers to the force and motion requirements of the actuators that are hydraulically driven in the main engine. The actuators have clear data on the magnitude of the force and speed required for each stage of the work, the range of speed adjustments, the smoothness of the speed, and the time to complete a cycle. Modern machinery requires high precision, high productivity and a high degree of automation, which not only requires its hydraulic system to have good static indicators, but also requires dynamic indicators.
