Variable Vane Pumps VVP1/VVP2 Series

VVP series variable vane pumps are single role limited pressure variable vane pump. The product is mainly composed of a stator, rotor, blade, oil pan, pressure spring, flow feedback pistons and other components. It through the stator and rotor eccentric mechanism and achieved with the oil pan and oil drain; spring and flow through the pressure feedback Pistons, according to the system pressure changes the stator and rotor eccentric output flow and pressure in order to achieve the best up with, reduce power loss; By flow, pressure adjustment screw can be adjusted separately flow and pressure; through the use of circular blades for low noise, no vibration.

The product is compact, small size, light weight, low noise, high efficiency, low power loss, cost performance, excellent features. For machine tools, hydraulic machinery, and there is variable and packing requirements of the low-pressure system. 2.Specification

Double vane pump works: it consists of stator, rotor, blade and oil pan and other components. The inner wall of the stator is approximately elliptical. The blade is mounted in the radial groove of the rotor and slides along the groove, and the rotor is mounted concentrically with the stator. When the rotor is rotated, the blade is pressed against the inner surface of the stator under the action of centrifugal force, and is forced to reciprocate in the rotor tank with the change of the inner surface curve of the stator, and the sealing working chamber between adjacent two blades is enlarged and shrunk Variety. When the blade is slid from a small radius arc to a large radius arc, the sealed working chamber gradually increases to form a local vacuum, and the oil in the tank is sucked through the oil suction chamber through the oil pan; Rotate the rotor every week, the blade in the tank to slip back and forth 2 times to complete the 2 oil and 2 times the pressure oil, and the pressure generated by the radial force is balanced, so called double acting, also known as balanced.
Single acting vane pump works: mainly by the stator, rotor, blade and oil pan and other components. The inner surface of the stator is a cylindrical shape, the rotor is eccentrically mounted in the stator, that is, an eccentric e, the blade is mounted in the rotor radial chute and slid radially within the slot. Rotor rotation, the centrifugal force and the role of the root pressure of the blade under the action of the blade close to the inner surface of the stator, so that between the two adjacent leaves to form a sealed working chamber. In one side, the blade gradually extended, sealed working chamber gradually increased, the formation of local vacuum, the formation of oil; the other hand, the other side, the formation of oil. Rotate each turn a week, the blade in the chute reciprocating slip 1 times to complete a suction oil pressure. Oil pressure generated by the radial force is not balanced, so called single acting, also known as unbalanced vane pump.
Vane Pumps
Power never sounds better than when it’s quiet—that’s why Eaton fixed displacement vane pumps with low-noise characteristics are an excellent choice for a broad range of mobile and industrial applications. Featuring modular designs for flexible displacement, mounting and port options, as well as cartridge kits engineered for easy interchangeability and repair, Eaton vane pumps excel globally in molding, material handling, construction, manufacturing and automotive industries
