What are the matters that need to be checked frequently

Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy, and the hydraulic cylinder is indispensable for normal operation and use, so the use of oil is very important. However, it should be noted that before starting, check the oil level and check whether the switch of each oil circuit is in the correct standby state.

The machine runs at idle speed for about 5min, check whether there are bubbles in the oil of the level gauge. If it is a new car or a new hydraulic oil, it is normal for bubbles to appear in the oil label during idle speed, and the machine can only be allowed to work after the bubbles disappear. At the same time, pay close attention to the temperature of the oil, when the machine works for a period of time, if the oil temperature is too high, it is recommended to stop and rest, and then work again after the oil temperature is normal, in order to extend the service life of the system and oil.

Attention should be paid to whether the various parameters of the hydraulic system are normal, and attention should also be paid to the external characteristics of the system - sound. If the system has air intake, water or oil circuit is not smooth, it will emit abnormal sound. At the same time, the reading fluctuation of the instrument shows that the value is not normal, and it should be stopped and checked in time.

In order to ensure the normal operation of the hydraulic cylinder, it is necessary to filter the hydraulic oil regularly to control the impurity particles in the oil within the specified range. According to the requirements of the machine manual, regular oil change, while replacing the oil filter, conditional detection, should be determined according to the results of the oil change; The oil change cycle can also be developed according to the site and system requirements of the machine, and the oil change cycle can be included in the equipment technical file.

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