In the process of using the loader, there will be some small problems due to the problems of loader accessories. We need to know some problems to maintain ourselves and prepare some loader accessories at the same time.
? the loader has been put into gear, but the loader is weak and even unable to walk. The reasons are as follows:
??1. The clutch piston ring and seal ring are seriously worn, resulting in serious leakage.
??2. The clutch automatic emptying valve is not tightly sealed, which reduces the pressure;
??3. The shut-off valve cannot return;
??4. The friction plate is seriously worn and the clearance is too large;
??5. The positioning spring of variable speed valve is tired or broken, and the steel ball jumps;
??6. The pipeline of shift operation valve is blocked;
? the gearbox of loader is divided into manual shift and power shift according to the operation mode: 1. Manual shift: manually move the gear or meshing sleeve to shift. The manual shift transmission has simple structure, but the operation labor intensity is high. When shifting gears, the power cut-off time is long, which will affect the productivity of the loader, and the passing performance is poor when driving on bad roads. 2. Power shift: the combination and separation of gear and shaft are realized through hydraulic clutch. The pressure source of hydraulic control is provided by the hydraulic pump driven by the engine. The combination and separation of the clutch test the power of the engine. The power shift operation is light, simple and fast, which is conducive to improving productivity. As the loader shifts frequently during operation, the application of loader has many advantages, which is also a common one at present.
