20V Vane Pumps with Lower Noise

V Seriesvane pumps with lower noise are intra vane pumps, featured by advanced performance, high pressure, stable operation, lower noise, ultra-low pulse, long life-span and so on, and are widely used in cutting, plastic, leather, pressure , engineering, metallurgical machinery fields, and the like.

Installation and Use
1. In installation, the tolerance of concentricity between shaft of pump and motor must be less than 0.10mm (TIR) ​​and the maximum permissible angle error is less than 0.2 degrees by using the flexible coupling; The pump shaft shall not bear the radial and axial load ; The carrier must be firm with good rigidity and can fully absorb vibrations.

2. Fix pipes, especially inlet pipes in accordance with the size of port and assemble safety relief valves in the system (the inlet flow rate is between 0.5 and 1.5 m / s). The regulating pressure of the safety valve shall not be greater than the maximum pressure of the pump; Inlet pipes must be strictly sealed with no leakage; Inlet pipes must be strictly sealed with no leakage; The fuel tank shall be equipped with a diaphragm to separate the bubbles and dirt from the oil; The oil return nozzle should be lower the fluid surface, the minimum depth of 50 mm, even in a low, too, when the permissible level of to avoid the formation of bubbles.

3. Set the suction pressure at pump inlet port: oil hydraulic oil is + 35 ~ -16.7 KPa. The hydraulic oil of water-glycol and phosphate ester was + 35 ~ -10.1 KPa.

4. In case where the pump is installed on the tank or at the position higher than the tank top cover, the height of the suction port of the pump should be less than 500mm.

5. Oil should be kept clean, pipes and tanks must be thoroughly cleaned; Precise filters should be assembled with the advised precision of 25μm in the system, the cleanness level of oil should be within NSA12. Fix the sufficient-volume filter (the rated flow rate should be greater than twice the pump flow) at the inlet of the pump 50mm above the bottom of the tank, with the suggested precision of 100μm (150 mesh).

6. It is recommended to use antiwear industrial hydraulic oils or automotive crankcase oils having letter designations SC, SD, SE or SF with viscosity grades of 32 to 68 cSt at 40 ℃

Preferred viscosity at rated speed and pressures:

Min. 13cSt Max. 54cSt

Min. 49 ℃ Max. 65 ℃

7. Check the inlet, outlet and direction of rotation before starting the pump. Turn the shaft of pump evenly and nimbly by hand after fixing the pump. It is best to fill the pump with oil for the first time.

At an initial operation or at an operation after a long rest, the pump may have difficulty in sucking up fluid; In such cases, an air bleed valve should be installed beforehand on the discharge side or discharge air by slightly slackening the connection on the discharge side. At starting, operate the pump intermittently as far as possible with no load.

8. Do not start the pump when the outlet pressure is lower than the inlet pressure. This will cause work noise and blade instability.

9. At startup, If the oil viscosity is higher than the suitable viscosity (54cSt), the pressure should be limited to 50% or less of their respective rated values ​​until the system has warmed up.
