A10VSO140 Pump

A10VSO140 is a high-performance axial piston variable displacement pump, belonging to the Rexroth A10VSO series. It is usually used in hydraulic systems that require a large flow rate, such as large construction machinery, metallurgical equipment, ships, etc. Compared with other models in the A10VSO series, the A10VSO140 is larger in size and has a larger flow rate, making it suitable for high-load hydraulic systems.

Structure and Working Principle

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, thereby adjusting 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 the 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.

Working principle

By rotating the swash plate, the relative position between the piston and the cylinder is changed, thereby changing the output flow and pressure of the pump. The distribution plate controls the inflow and outflow direction of the hydraulic oil.

Common faults and causes

Leakage aging and damage of seals, wear of cylinder body, wear of distribution plate, etc.

Excessive noise bearing damage, gear wear, cavitation, foreign matter entering the pump body, etc.

Insufficient flow or pressure swash plate stuck, distribution plate wear, oil suction line blockage, hydraulic oil contamination, etc.

Overheating hydraulic oil viscosity is too high, cooling system failure, excessive load, etc.

Maintenance steps

Disassembly cut off the power supply, release the pressure, and disassemble the pump body in sequence.

Cleaning Use detergent and compressed air to clean each component thoroughly.

Inspection Check for wear and measure clearance.

Replacement Replace damaged parts.

Assembly Assemble in order, pay attention to tightening torque.

Debugging Connect the pipeline, inject hydraulic oil, start at low speed, and gradually increase the speed and pressure.

Maintenance precautions

Professionalism Maintenance requires professional knowledge and skills.

Special tools Use professional tools.

Spare parts quality Replace original or certified spare parts.

Cleanliness Keep the environment and parts clean.

Debug carefully Ensure that the pump performance meets the requirements.

Maintenance suggestions

Regular maintenance Regularly replace hydraulic oil and check the filter.

Avoid overload Avoid long-term overload operation of the pump.

Pay attention to cooling Ensure that the pump has good cooling conditions.

Professional maintenance Regular inspection and maintenance by professionals.
