What is the cause of loader failure that the loader parts supplier told you?

During the use of the loader, due to one or several reasons, the power, economy, reliability and safety change, and the normal working conditions are damaged gradually or suddenly, that is, the loader has a fault. There are several reasons for the failure of the loader.
1. Faults caused by defects and weak links of loader design manufacturer
The improvement of the design structure of modern loaders, the adoption of new processes, new technologies and new materials in manufacturing, and the improvement of processing and assembly quality have indeed greatly improved the performance and quality of national war loaders. However, the structure of loader is more complex than that of automobile and tractor; There are many kinds and specifications, even the same ZL50 loader. There are still great differences in the design of different manufacturers. Therefore, the working conditions of various assemblies, assemblies and parts of the loader vary greatly, and it is impossible to fully adapt to various operating conditions and working environment. Some weak links will be exposed in use, especially those newly put into operation
      

2. Faults caused by quality problems in parts manufacturing
At present, the loader adopts the socialized production mode. The main engine factory mainly knows the structural parts and assembly, while most parts are produced by the parts factory. Due to the different equipment conditions, technical level and operation and management level of these parts factories, the impact of various events in the factory on the thoughts and emotions of employees due to the tension and relaxation between work areas in different periods. Will make the quality of parts unstable. For example, the hydraulic cylinder, especially the cylinder with the guide sleeve connected with the cylinder barrel by the internal key, has not been completely solved by a hydraulic parts factory so far. This design does not ensure the technical level of the current workers. In the assembly operation with high efficiency of the cylinder loader, the O-ring on the guide sleeve and the reverse lip seal on the piston will not be damaged. This kind of Sun Hua can't be found in the short-term inspection of the main engine factory when it is produced in the parts factory, and the leakage gradually occurs after the user uses it for a period of time. At the same time, the reverse lip seal ring of the piston is flushed, which is that the hydraulic cylinder can't work normally.
Due to the quality problems of parts manufacturing, there are many faults of the loader, so we must fully understand the structure and working principle of various parts of the loader.
3. Influence of fuel and lubricating oil quality
Reasonable selection of fuel and lubricating oil of loader is a necessary condition to ensure the normal operation of loader. For example, the lubricating oil used for torque converter and gearbox must be turbine oil and hydraulic oil of good quality. Otherwise, due to improper oil use, the oil temperature of torque converter system will be too high, which will bring a series of faults.
4. Poor management and use, failure to implement the planned preventive maintenance system, and poor maintenance quality.
The above is the information sorted out by the loader accessories manufacturer. I hope it can help you.
