Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. Hydraulic oil is essential for the normal operation and use of hydraulic cylinders, so the state of oil use is very important. However, it should be noted that before starting up, check the oil level and ensure that the switches of each oil circuit are in the correct standby state.

Idle the machine for about 5 minutes and check if there are any bubbles in the oil level gauge. If it is a new car or a newly replaced hydraulic oil, it is normal for bubbles to appear in the oil gauge during idle. The machine can only be allowed to operate after the bubbles disappear. At the same time, close attention should be paid to the temperature of the oil. If the oil temperature is too high after the machine has been operating for a period of time, it is recommended to stop the machine and rest. After the oil temperature is normal, it can be restarted to extend the service life of the system and oil.

Attention should be paid to whether the various parameter values of the hydraulic system are normal, and also to the external characteristics of the system - sound. If there is air intake, water or poor oil circuit in the system, abnormal noises will be emitted. At the same time, if the reading fluctuation of the instrument is abnormal, the machine should be stopped and checked in a timely manner.

In order to ensure the normal operation of the hydraulic cylinder, it is necessary to regularly filter the hydraulic oil to control the impurities and particles in the oil within the specified range. Regularly change the oil according to the requirements of the machine manual, and replace the oil filter at the same time. If conditions permit inspection, determine whether to change the oil based on the results; The oil change cycle can also be formulated based on the site and system requirements of the mechanical device, and included in the equipment technical file.

Hydraulic oil plays a role in energy transmission, anti-wear, system lubrication, corrosion prevention, rust prevention, cooling, and other functions in hydraulic systems. In order to better ensure its usage status, it is necessary to do relevant work before and after use, so that the hydraulic cylinder can also have better operation status.
