The hydraulic system in the process of operation to a certain extent to be familiar with the operation essentials of its hydraulic components control mechanism to a certain extent to be familiar with the relationship between the rotation direction of the adjusting knob of its hydraulic components and the change of pressure and flow rate, etc., to prevent accidents caused by adjustment errors.

The pump of the hydraulic system needs to check its oil temperature effectively before starting. If its oil temperature is lower than 10 degrees, to a certain extent, it should run for more than 20 minutes without load before loading and running. If its temperature is below 0C or higher than 35°C when in use, it should take heating or cooling measures before starting.

Hydraulic system in the process of work need to pay attention to the oil temperature at any time, at the time of normal work, one strands of the temperature of the hydraulic system of the oil tank is no more than 60 degrees, the program controlled machine tool hydraulic system or a high pressure system of oil tank temperature should not exceed 50 ℃ of precision machine tool temperature should be controlled below 15 ℃.

The hydraulic oil of the hydraulic system needs to be checked and replaced clearly when it is in use. During operation, the newly put into use of the hydraulic equipment should be cleaned and replaced within 3 months to a certain extent. In the future, the oil tank should be cleaned and replaced once every half a year or once a year according to the requirements of the equipment manual. 

In the use of the hydraulic system should pay attention to the working condition of its filter, its filter element should be regularly cleaned or replaced, the equipment if not, should be all the adjustment knob relaxed, to prevent the spring deformation and affect the performance of components.

Hydraulic system action requirements of the host, is mainly refers to the host when operate with or without contact between action and accomplish a certain number of automatic cycle, and so on, when operating the host may make as many requirements for hydraulic system, the designers should know the host USES in the working process and the overall layout on the basis of making analysis to these requirements.

Hydraulic system refers to the use of hydraulic transmission in the host actuator in the force and movement of the requirements, each actuator in each working stage required force and speed size, speed range, speed stability and the completion of a cycle of time and other aspects have clear data. Modern machinery requires high precision, high productivity and high automation, which not only requires its hydraulic system has a good static index, but also requires its dynamic index.
