Taiwan KQK Vane pump rotor, blade in the centrifugal force and oil pressure under the action of the tip, close to the inner surface of the stator. The volume of work that two blades and rotor and stator inner surface of the first large, after oil absorption from large to small oil, rotating blades of a week, the completion of the two oil suction and discharge of oil.
The working principle, the single action vane pump
First,Pump is composed of rotor, stator blade 2, 1 3, valve plate and the end cover and other parts. The inner surface of the stator is a cylindrical hole. There exist eccentricity between stator and rotor. Leaf blade in the rotor slots can be flexibly slide, centrifugal force when the rotor rotates and pass into the blade root pressure oil, the top of blade tightly on the inner surface of the stator, and the two adjacent blade, plate, between the stator and the rotor, they form a sealed working chamber. When the rotor according counterclockwise, drawing on the right side of the blade extends outward, the sealing chamber volume increases, resulting in vacuum, then through the suction port 6 and oil pan with 5 windows on the oil suction. In the left-hand side of the diagram. Leaf blade to indent, volume sealed cavity gradually narrowed, seal oil cavity in the pan with oil another window and pressure oil port 1 is pressed while the output in the system. This process of pump in the rotor of a turn, the oil pressure oil each time, so that a single action pump. Rotor subjected to radial hydraulic imbalance force, so it is also called non balanced type pump, the larger the bearing load. Changing the eccentricity between the stator and the rotor, and can change the capacity of pump, the pump is a pump.
Second , the working principle of double acting vane pump
Action principle and the single action vane pump is similar, the difference is in the surface of the stator is composed of eight parts of two long radius, two short radius and four transition curves, and the stator and rotor are concentric. In this case the rotor along clockwise, volume sealed working chamber in the upper left and lower right corner is increasing, as the absorption area, in the lower left and upper right corner decreases gradually, as the pressure oil; oil pressure oil between the region and has a sealing oil separated them from the. The pump rotor each turn, each sealed working chamber absorbing oil and two oil pressure action, so called the double action vane pump. Two absorption area and two pressure oil pump is radially symmetric, radial equilibrium liquid pressure acting on the rotor, it is also known as balanced vane pump.
The instantaneous flow of double action vane pump is fluctuating, when multiple blade number 4 pulsation rate. Therefore, the number of leaves of double action vane pump is generally take 12 or 16.
