Maintenance content of hydraulic system of wheel loader

When we buy a loader, the care and maintenance of the loader is a very important part. Regular maintenance and maintenance can help the loader extend life, reduce downtime, and improve work efficiency. Today, with OXPLO brand to understand the loader maintenance knowledge.

The daily maintenance of the loader can be divided into several parts, of which the hydraulic system plays an important role in the wheel loader, converting the hydraulic oil into fluid power through the hydraulic pump, providing power and driving force for the various hydraulic actuators of the loader. This includes hydraulic cylinders, hydraulic motors and hydraulically driven transmission devices, etc. The power transmission capacity of the hydraulic system is strong, which can provide sufficient thrust and torque to enable the loader to carry out various work tasks, such as lifting, tilting and pushing heavy objects. The hydraulic system can also control the flow direction, flow rate and pressure of the hydraulic oil through the hydraulic valve, so as to achieve a variety of movement and operation control of the loader. For example, the hydraulic system can control the lifting of the loading bucket. Tilt and automatic balancing enable loaders to perform loading, unloading, stacking and leveling work effectively. The hydraulic system can also be used to drive various auxiliary functions of the loader, such as hydraulic power head, hydraulic fixture, hydraulic rotating platform, etc. These auxiliary devices are controlled by the hydraulic system, so that the loader has a variety of functions and diversified application capabilities.

Hydraulic system is an important power and control system of wheel loader. It can provide powerful power output, accurate motion control and multi-functional application capability for loader. The reliability and performance of hydraulic system directly affect the working efficiency, operational flexibility and safety of loader. Therefore, in the daily maintenance, the maintenance of the hydraulic system is very worthy of attention.

The first is to choose the right hydraulic oil, the use of inappropriate hydraulic oil may have the following effects on the hydraulic system of the loader.

1. Reduce system performance: the hydraulic system needs to operate under a certain working pressure and temperature. The use of improper hydraulic fluids may result in reduced system performance, such as reduced speed, power and efficiency of the hydraulic system. This may affect the working capacity and production efficiency of the loader.

2. Leakage and sealing problems: Unsuitable hydraulic oil may be incompatible with the seal, resulting in aging, expansion or rupture of the seal, resulting in leakage. Leakage will cause the hydraulic system pressure drop and the normal operation of the hydraulic components to be blocked.

3. Deposits and clogging: The use of unsuitable hydraulic oil may contain impurities, additives mismatch or excessive obsolescence, which may lead to the formation of deposits. Sediment can clog the pipes, valves and filters of the hydraulic system, affecting fluid flow and pressure transfer, thereby reducing the efficiency and reliability of the system.

4. Damage to hydraulic components: Unsuitable hydraulic oil may not provide adequate lubrication and protection, resulting in increased wear of hydraulic components such as hydraulic pumps, valves, and cylinder blocks. This can lead to damage, leakage and failure of components, which can lead to more serious failures. Even caused the loader to stop.

5. Temperature control problem: hydraulic oil plays the role of cooling and temperature control in the hydraulic system, and unsuitable hydraulic oil may lead to too high or too low temperature, affecting the stability and working life of the hydraulic system.

It is also necessary to prevent solid impurities from mixing into the hydraulic system, such as particles, dust, metal chips, etc., if they enter the hydraulic system, they may be suspended or deposited in the fluid. These impurities may enter the hydraulic pump, valve. Cylinder block and other hydraulic components, causing wear, scratches and damage. Long-term accumulation of solid impurities can lead to early failure of components and shorten the life of the hydraulic system.

Solid impurities can also clog pipes, valves, and filters in hydraulic systems. This impedes the normal flow of fluids, resulting in reduced pressure, reduced flow, and reduced system performance. Clogging the filter will also cause the filter to not work properly and cannot effectively remove other impurities in the fluid, making the cleanliness of the hydraulic system difficult to maintain.

Solid impurities can also damage seals in hydraulic systems, leading to leakage problems. The presence of impurities will increase the risk of wear and damage to the seal, and reduce the sealing performance. Leakage will lead to pressure loss of the hydraulic system, affecting the efficiency and performance of the system.

Hydraulic systems require precise pressure and flow control to achieve accurate movement and operation. The presence of solid impurities will interfere with the control and adjustment of the hydraulic system, resulting in a decline in the accuracy and stability of the system. This can affect the accuracy, smoothness and handling performance of the loader.
