Double variable vane pump VB1B1 Series

Double variable vane pump VB1B1 Double variable vane pump VB1B1 (low pressure) Features1, double variable vane pump VB1B1 (low pressure) by two pairs of variable vane pump VB1B1 (low pressure) combined with one, using a common drive shaft.2, double variable vane pump VB1B1 (low pressure) by a motor-driven, reducing installation space.3, double variable vane pump VB1B1 (low pressure) can also supply pressure and flow of different circuits.4, double variable vane pump VB1B1 (low pressure) easy assembly, composed of the motor can be directly coupled motor pump combination. Double variable vane pump VB1B1 (low pressure) Model Description
vane pumps Double variable vane pump VB1B1 Series
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.
