Trade assurance SVPDF series SVPDF-3070-3070-20 Double variable vane pump

Product Features:

The hydraulic vane pump is a pump in which the vane in the rotor groove contacts with the pump housing (stator ring) and pushes the suction liquid from the oil inlet side to the oil outlet side. In addition to the management of the hydraulic vane pump need to prevent dry rotation and overload, prevent the inhalation of air and vacuum too large, should also pay attention to:
1. Hydraulic vane pump steering change, then its suction and discharge direction also changes the hydraulic vane pump have a specified steering, not allowed to reverse. Because the rotor cotyledon groove is inclined, the blade is chamfered, the bottom of the blade is connected with the oil discharge chamber, and the throttle groove and suction and outlet on the oil distribution plate are designed according to the established steering. Reversible hydraulic vane pumps must be specially designed.
2. Assembly of hydraulic vane pump: oil distribution plate and stator: pin is correctly positioned, the blade, rotor, oil distribution plate shall not be installed in reverse, the stator inner surface suction area is easy to wear, when necessary, the hydraulic vane pump can be reversed installation, so that the original suction area into the discharge area and continue to use.
3. Hydraulic vane pump disassembly: pay attention to the clean working surface, working oil should be well filtered.
4. The clearance of the hydraulic blade pump blade in the blade groove is too large to increase leakage, too small, the blade cannot freely expand, will lead to work disorders.
5. The axial clearance of hydraulic vane pump had a great influence on eta v.
1) small hydraulic blade pump -0.015 ~ 0.03mm 2) medium hydraulic blade pump -0.02 ~ 0.045mm
6. Oil temperature and viscosity generally should not exceed 55℃, viscosity requirements between 17 ~ 37mm2 / s. Too large viscosity is difficult to absorb oil; If the viscosity is too small, the leakage is serious.
