In the process of operation, the hydraulic system must be familiar with the operation essentials of the hydraulic element control mechanism like hydraulic workholding. It is necessary to be familiar with the relationship between the rotation direction and pressure of the adjustment knobs of the hydraulic components and the change of the flow rate, and to prevent accidents caused by adjustment errors. The pump of the hydraulic system should check the oil temperature before starting, and make the oil temperature lower than 10°C. In this case, it is necessary to run for more than 20 minutes without load to operate the pump.
If the room temperature is below 0°C or higher than 35°C, heating or cooling measures should be taken before starting. Always pay attention to the oil temperature rise during work. In normal operation, the temperature of the fluid in the general hydraulic system tank should not exceed 60°C. The hydraulic oil in the hydraulic system needs regular inspection and replacement when it is in use. In the process of use, the newly-used hydraulic equipment should be cleaned and replaced with new oil within about 3 months of use. Afterwards, cleaning and oil change should be performed every six months or one year according to the requirements of the equipment instructions. When the hydraulic system is in use, if the equipment is not used for a long time, all adjustment knobs should be loosened to prevent the permanent deformation of the spring and affect the performance of the components. The hydraulic system is an integral part of the mainframe.
When designing the hydraulic system, it is first necessary to clarify the hydraulic workholding requirements placed on the hydraulic system by the host. The performance requirements of the mainframe of the hydraulic system are mainly the requirements of the hydraulic transmission actuators in various aspects of force and movement during use. The force and speed required by each actuator in each working phase, the speed range and speed The stability and the time to complete a cycle have clear data. Modern machinery requires high precision, high productivity, and high degree of automation. This requires not only its hydraulic system has a good static index, but also its dynamic indicators.
