NACHI VDR-1B-2A2-22 Series High-Pressure Type Variable Volume Vane Pump

Features 1)Highly efficient and stable high-pressure operation Innovative pressure control and pressure balance mechanisms combine with an original 3-point ring support system dramatically improves high-pressure operation. The result is outstanding performance at high pressures up to 14MPa.2)Low vibration and noiseA number of innovative new mechanisms are adopted to minimize vibration and noise. In particular, a 3-point support system is used for the control piston and bias piston to increase ring stability. This minimizes ring vibration and delivers quiet operation.3)Outstanding response,high-precision operationAn innovative new ring stopper eliminates excessive ring displacement and improves response. The result is high precision operation at all times, including during starts, stops, and load changes.4)Precise characteristics for a stable discharge rateA revolutionary new pressure compensator type pressure control mechanism ensures a highly stable fixed discharge rate, even in the high pressure range.5)High efficiency operation withminimal power lossNew mechanical innovations minimize power loss, especially at full cutoff.6)Simplified maintenance and handlingPressure adjusting and discharge rate adjusting mechanisms are located on the same side of the pump for simplified maintenance and handling.

vane pumps NACHI VDR-1B-2A2-22 Series High-Pressure Type Variable Volume Vane Pump
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.
