A10VSO28 Pump

A10VSO28 is a high-performance axial piston variable displacement pump, which belongs to the Rexroth A10VSO series. It is generally used in hydraulic systems that require medium flow, such as small to medium-sized construction machinery, machine tools, injection molding machines, etc. Compared with other models in the A10VSO series, A10VSO28 has moderate size, moderate flow, and relatively simple structure, but it also has the advantages of high efficiency, low noise, and long life.

Main components of A10VSO28 pump

Cylinder body Contains the piston and cylinder barrel, usually made of high-strength cast iron or alloy materials to withstand high pressure.

Swash plate Controls the angle of the piston and thus adjusts the output of the pump.

Port plate Guides the flow direction of the hydraulic oil in the pump, and the material is usually wear-resistant alloy steel to reduce wear.

Piston and shoe assembly Converts the rotational motion of the swash plate into linear motion of the piston. The piston is made of wear-resistant alloy steel, and the boot is made of wear-resistant rubber or polyurethane to ensure sealing.

Bearing assembly supports rotating parts and reduces friction, usually with high-precision bearings to improve pump efficiency and life.

Shaft transmits power from the drive motor to the pump, made of high-strength alloy steel to withstand torque.

Seal kit prevents internal leakage and contamination, and the sealing material is usually fluororubber, nitrile rubber, etc. to ensure the cleanliness of the system.

Common parts of A10VSO28 pump

Piston and boot assembly due to the harsh working environment, it is easy to wear and is usually replaced as a set.

Seal kit includes various seals such as O-rings, shaft seals and piston seals. Replace regularly to prevent leakage. [A10VSO28 seal kit image]

Distribution plate controls the direction of fluid flow, and may wear and leak after long-term use.

Bearing assembly supports the rotating shaft, which may be damaged by contamination or overload, resulting in increased pump noise or poor operation.

Swash plate controls the output of the pump, and excessive wear or misalignment may cause unstable flow or leakage.

Common A10VSO28 Pump Problems and Solutions

Leaks Caused by worn seals, damaged O-rings, or excessive cylinder wear. Solution Replace damaged seals or components.

Reduced flow May be caused by worn swashplate, clogged suction pipe, or internal leaks. Solution Inspect and replace worn parts, check for blockages.

Excessive noise Usually caused by cavitation, worn bearings, or misalignment. Solution Check for air in the system, replace worn bearings, and ensure proper alignment.

Overheating May be caused by insufficient cooling, excessive loads, or contaminated hydraulic fluid. Solution Check cooling system, reduce loads, and replace hydraulic fluid if necessary.

A10VSO28 Pump Maintenance Recommendations

Regular hydraulic fluid analysis Monitor hydraulic fluid for contamination and degradation.

Filter element replacement Replace filter elements according to manufacturer recommendations.

Check for wear Regularly inspect the pump for signs of wear such as scratches or pits.

Proper lubrication Make sure all moving parts are properly lubricated.

Avoid overloading Operate the pump within rated capacity.

Differences between A10VSO28 and other A10VSO series pumps

The main differences between A10VSO28 and other models in the A10VSO series are size and flow. A10VSO28 has moderate size and flow, suitable for medium flow hydraulic systems.

Summary

A10VSO28 is a high-performance hydraulic pump suitable for medium flow hydraulic systems. Due to its relatively simple structure, maintenance is relatively easy. Regular maintenance and inspection can extend the service life of the pump and improve the reliability of the system.
