25v-21a-1a-22r vane pump instructions

1. Product model analysis

Series number: 25V, indicating that the vane pump belongs to the 25V series and is suitable for medium and high pressure hydraulic systems.

Geometric displacement: 21, represents the specific displacement of the hydraulic pump to meet the flow requirements under different working conditions.

Oil port connection form: A, indicating that the oil port is connected by a spiral flange, which is easy to install and disassemble.

Shaft extension type: 1 represents that the oil pump has a flat key shaft extension.

Oil outlet position: Viewed from the cover end of the pump, A represents that the oil outlet of this hydraulic vane pump is located opposite to the oil inlet.

Design number: 22, represents the design version or improved model of the pump.

Rotation direction: R, indicating that the pump rotates clockwise, which meets the design requirements of most hydraulic systems.

2. Product Features

High efficiency and stability: The advanced vane pump design ensures high efficiency and stable performance under high pressure conditions.

Wear-resistant and durable: Key components such as blades, rotors and stators are made of high-quality wear-resistant materials to extend the service life of the pump.

Compact structure: small size, light weight, easy to install and use in limited space.

Easy maintenance: Reasonable structural design, easy to disassemble and maintain, reducing maintenance costs.

3. Working Principle

The working principle of the 25v-21a-1a-22r vane pump is based on the fact that the vanes are tightly attached to the inner surface of the stator under the action of centrifugal force and pressure oil. As the rotor rotates, the working volume formed by the vanes, the rotor and the inner surface of the stator first absorbs oil from small to large, and then discharges oil from large to small. Every time the rotor rotates one circle, it completes the oil absorption and discharge process twice, thereby realizing the continuous delivery of hydraulic oil.

4. Installation and debugging

Preparation before installation: Check whether the pump body and accessories are intact and ensure that the installation environment is clean and free of impurities.

Installation steps: Install according to the installation diagram in the product manual, paying attention to the oil port direction and rotation direction.

Debugging and inspection: After installation, conduct a no-load test run to check whether the pump body has abnormal vibration and noise. Gradually load to rated working conditions to check whether the pressure and flow of the pump meet the design requirements.

5. Notes

Operational safety: During the operation, the safe operating procedures should be strictly observed to prevent accidents.

Maintenance: Check the wear of the pump body and accessories regularly, and replace damaged parts in time. Clean the inside of the pump body regularly to keep the oil clean.

Storage environment: Unused hydraulic oil pumps should be stored in a dry, ventilated environment without corrosive gases to avoid moisture and corrosion.
