1. Installation

The hydraulic vane pump installation must avoid using belts, chains, and gears to directly drive the hydraulic vane pump. It is recommended to use a coaxial direct motor drive and use a flexible connection or a spline connection. For coaxial cables within the tolerance range of mm, a rotary flexible coupling with gap error compensation and angle error compensation should be used. In order to avoid damage to bearings, oil seals, etc. due to the concentricity of the two, noise, vibration and even accidents may occur.

2. Turn

The standard hydraulic vane pump should be rotated clockwise when viewed from the shaft end, otherwise it is regarded as a reverse hydraulic vane pump, and no oil should be added when the forward hydraulic vane pump rotates counterclockwise.

3. Start

When the hydraulic vane pump is started for the first time, the trapped air must be removed from the system. Generally, you can loosen the oil outlet pipe joint of the hydraulic vane pump to exhaust, or use the air release valve to exhaust. For low-flow hydraulic vane pumps with poor self-priming, etc., the hydraulic vane pump must be filled with oil through the drain pipe or the inlet pipe before starting. In a short period of time, rapid opening and closing of the hydraulic vane pump can also quickly fill the hydraulic vane pump with oil and discharge. When starting, the relief valve must be fully opened, that is, the system starts under no pressure, and the motor rotation is checked.


4. Filtration requirements

In order to ensure the reliability of the hydraulic vane pump, the oil should be filtered with full flow to make the oil cleanliness meet the IS04406 standard of 19/15 or cleaner hydraulic oil (such as 16/13). The 150-point suction line is recommended. Suction oil filter, oil return pipe 25 to 10 industry filter.

5. Hydraulic oil

Generally, the hydraulic vane pump uses anti-wear hydraulic oil with a viscosity of 25-68cst. The difference between the hydraulic vane pump body and the oil temperature is controlled within 20 ° C, and the oil temperature should not exceed 60 ° C. Different hydraulic oils have different working oil temperatures.

6. Pump speed

You can refer to the provisions of the hydraulic vane pump instruction manual, the general hydraulic vane pump speed range is 600 ~ 1800r / min.
