Vane pump through the rotation of the impeller, the power of mechanical energy into water (potential energy, kinetic energy, pressure energy) hydraulic machinery. Vane pump products generally do not call the vane pump. However, as a monograph, vane pumps almost all refer to centrifugal pumps, mixed flow pumps, axial flow pumps and the like. Vane pump specifically refers to the volume pump in the vane pump. Vane pump refers to the three pump (centrifugal pump, mixed flow pump, axial flow pump) or other special pumps. Vane pump according to its theoretical displacement per revolution is a fixed value or variable value, can be divided into variable vane pump and vane pump. The following is a million hardware and electronic machinery Xiaobian for everyone to provide what is the vane pump? Vane pump features what? What is the working principle of vane pump? Vane pump rotor rotation, the blade under the action of centrifugal force and pressure oil, the tip close to the inner surface of the stator. This two leaves and the rotor and the inner surface of the stator form the working volume, first small to large after the oil from large to small oil discharge, blade rotation a week to complete two oil and oil drain. First, the single-acting vane pump principle Pump by the rotor 1, stator 2, the blade 3, with oil pan and cover and other components. The inner surface of the stator is a cylindrical hole. Eccentricity exists between rotor and stator. The vane slides flexibly in the slot of the rotor, and the top of the vane is in close contact with the inner surface of the stator under the centrifugal force when the rotor rotates and the pressure oil is introduced into the root of the vane. Two adjacent vanes, oil pan, stator and rotor Between the formation of a sealed working chamber. When the rotor is rotated counterclockwise, the right side of the blade extends outwards, the volume of the working chamber is gradually increased and a vacuum is generated, so that the oil is sucked in through the oil suction port 6 and the upper window of the oil distribution disk 5. And on the left side of the graph. Indenting the blades inwards, the volume of the sealed chamber is gradually reduced, and the oil in the sealed chamber is pressed out through another window of the oil pan and the pressure port 1 to be output to the system. This pump in the rotor turn process, the suction pressure of the oil once, it is called a single role in the pump. Rotor radial hydraulic imbalance force, it is also known as non-balanced pump, the bearing load larger. Change the amount of eccentricity between the stator and the rotor can change the pump displacement, so this pump is a variable pump. Second, the working principle of dual-acting vane pump Its role and principle of single-action vane pump similar, only difference is that the stator surface is composed of two sections of long radius arc, two sections of short radius arc and four sections of the transition curve of eight parts And the stator and rotor are concentric. In the case of a clockwise rotation of the illustrated rotor, the volume of the sealed working chamber gradually increases in the upper left corner and the lower right corner, which is the oil absorption zone, and gradually decreases in the lower left corner and the upper right corner as the pressure oil zone. The oil absorption zone And a pressure zone between the oil zone to separate them. This pump rotor per revolution, each sealed working chamber to complete the suction and pressure movements twice, so called double-acting vane pump. Pump two suction zone and two pressure zone is radial symmetry, the role of the rotor radial force balance, it is also known as the balanced vane pump. The double-acting vane pump has a pulsating instantaneous flow rate and low pulsation when the number of vanes is a multiple of four. To this end, the number of double-acting vane pump leaves generally take 12 or 16.
