Hydraulic oil is the use of liquid pressure energy hydraulic system used by the hydraulic medium, hydraulic cylinder to normal operation is not without hydraulic oil, so the use of oil state is very important. However, it should be noted that the oil level should be checked before starting up to check whether the opening of each oil circuit is in the correct standby state.

Machine idle running around 5 min, check whether there are air bubbles in the liquid level meter oil exists, if it is a new car or a new change of the hydraulic oil, oil rapidly when the bubble is in normal, such as bubble disappear to allow machine operation at the same time, please pay close attention to the oil temperature when the machine work after a period of time if the oil temperature on the high side suggested that stop to rest, to work again after the oil temperature is normal, to extend the service life of system with oil.

Attention should be paid to the hydraulic system parameters are normal, but also pay attention to the external characteristics of the system - sound. If the air inlet, water or oil circuit is not smooth in the system, abnormal sound will be sent out, and the fluctuating display value of the meter is not normal. In this case, stop the machine in time for screening.

The hydraulic cylinder manufacturer emphasizes that, in order to ensure the normal operation of the hydraulic cylinder, it is necessary to specify the filtration hydraulic oil, so that the impurity particles in the oil are controlled within the specified range. Oil shall be changed regularly in accordance with the requirements of the machine manual, and oil filter shall be replaced at the same time. If conditions permit, oil shall be changed according to the results. In addition, oil change cycle can be formulated according to the requirements of the site and system of mechanical equipment, and the oil change cycle shall be included in the technical documentation of equipment.

Hydraulic oil in the hydraulic system plays a role in energy transfer, anti-wear, system lubrication, corrosion, rust, cooling and so on. In order to better ensure its service state, relevant work needs to be done before and after use, so that the hydraulic cylinder can also have a better running state.
