Loader hydraulic system is one of the core components of the loader, used to realize a variety of hydraulic transmission and control functions of the loader. It includes hydraulic pumps, hydraulic cylinders, hydraulic valves and other components of the hydraulic components, as well as hydraulic tanks, oil pipes, filters and other auxiliary equipment.Next, take LY942 loader as an example to introduce its function principle in detail.

The hydraulic cylinder is a very important part of the 942 small wheel loader. In daily use, it may be damaged by some external debris, leaving scratches, which will destroy the sealing performance of the hydraulic cylinder and lead to hydraulic oil leakage. This will reduce the working pressure and efficiency of the hydraulic system, resulting in reduced performance of the 942 small wheel loader, in addition, the leaking hydraulic oil may contaminate the working environment, creating a danger to other machine components and operators. 

The seals of the hydraulic cylinder will also be damaged as a result, such as seals and O-rings. Seal failure will cause the hydraulic cylinder internal and external pressure imbalance, reduce the operation accuracy and stability of the 942 Compact Wheel Loader. At the same time, seal failure can also lead to the entry of dust, moisture or other impurities, accelerating the wear and failure of the hydraulic cylinder. Scratches will also increase the friction and resistance inside the hydraulic cylinder, making the efficiency of the hydraulic system decrease. The smooth movement and responsiveness of the hydraulic cylinder are affected, which affects the operational performance and response time of the loader. 

If the scratch is very serious or neglected to repair, it may lead to further damage to the cylinder, and the scratch may expand or deepen, damaging the internal structure and parts of the hydraulic cylinder. This will cause the hydraulic cylinder to fail, requiring the entire cylinder to be replaced, increasing maintenance costs and downtime.
