A11VO pump

The A11VO pump is an axial piston variable displacement pump produced by Rexroth, mainly used for hydrostatic transmission in open circuit hydraulic systems. It is known for its compact structure, high efficiency and strong reliability, and is widely used in engineering machinery, agricultural machinery, industrial equipment and other fields.

Working principle of A11VO pump

The working principle of A11VO pump is similar to other axial piston pumps. The relative position between the piston and the cylinder barrel is changed by rotating the swash plate to adjust the flow rate. Its main working parts include

Cylinder body accommodates the piston and cylinder barrel and withstands high pressure.

Swash plate controls the angle of the piston and adjusts the output of the oil pump.

Port plate guides the flow direction of hydraulic oil.

Piston and boot assembly converts the rotational motion of the swash plate into linear motion of the piston.

Bearing assembly supports rotating parts and reduces friction.

Shaft transmits power.

Seal prevents internal leakage.

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

Insufficient flow or pressure The inclined plate is stuck, the distribution plate is worn, the suction line is blocked, the hydraulic oil is contaminated, etc.

Overheating The viscosity of the hydraulic oil is too high, the cooling system fails, the load is too large, etc.

Repair and maintenance of A11VO pump

Regular inspection Check the oil level, filter cleanliness, seal status, etc. regularly.

Replace hydraulic oil Replace hydraulic oil regularly according to the use environment and manufacturer's recommendations.

Clean filter Clean or replace the filter regularly to prevent impurities from entering the pump body.

Check seals Check seals regularly and replace aging or damaged seals in time.

Professional repair For complex faults, repairs should be performed by professionals.

Precautions for purchasing A11VO pump

Choose a regular manufacturer Choose a manufacturer with a good reputation and after-sales service.

Understand product parameters Understand the flow, pressure, speed and other parameters of the pump in detail to ensure that they meet the use requirements.

Request relevant certificates Request product certificates, test reports, etc.

After-sales service Understand the manufacturer's after-sales service policy to ensure timely support during use.
