The following five aspects must be clarified before using Hydraulic Vane Pumps

1. Installation

The installation of hydraulic vane pump must avoid using belts, chains, gears to directly drive the hydraulic vane pump. It is recommended to drive the hydraulic vane pump directly with coaxial and flexible connection or spline connection; when connected to the motor, the hydraulic vane pump shaft and the motor shaft must be within 0.05 For coaxial lines within the tolerance range of mm, a rotary flexible coupling with clearance error compensation and angle error compensation should be used. In order to avoid damage to bearings, oil seals, etc., noise, vibration, or even accidents due to the misalignment of the two.

2. Turn

The standard hydraulic vane pump should rotate clockwise when viewed from its shaft end, otherwise it is regarded as a reverse hydraulic vane pump, and the forward rotation hydraulic vane pump will not be oiled when it rotates in the counterclockwise direction.

3. Start

When the hydraulic vane pump is first started, 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 exhaust valve to exhaust. For low-flow hydraulic vane pumps with poor self-priming, the hydraulic vane pump must be filled with oil through the drain or inlet pipe before starting the hydraulic vane pump. In a short period of time, the rapid opening and stopping of the hydraulic hydraulic vane pump can also make the hydraulic vane pump quickly fill and exhaust. When starting, the overflow valve must be fully opened, that is, the system is started under no pressure, and the motor rotation direction is checked.

4. Filtration requirements

In order to ensure the reliability of hydraulic vane pumps, the oil should be filtered with full flow to make the cleanliness of the oil meet the IS04406 standard 19/15 or cleaner hydraulic oil. The oil suction line is recommended to use a 150-mesh oil suction filter and oil return pipe. 25～10 industry filters.

5. Hydraulic oil

Generally, hydraulic vane pumps use anti-wear hydraulic oil with a viscosity of 25 to 68 cst. The temperature difference between the hydraulic vane pump body and the oil is controlled within 20 ℃, and the oil temperature must not be higher than 60 ℃. Different hydraulic oils have different working Oil Pumps temperatures.
