The pump shaft with the flow radial piston pump, the pump stator and rotor, two eccentric arrangement of the rotor mounted on the shaft with the flow, open circumferential direction of the rotor with seven holes uniform plunger, the plunger can be where the flexible movement. * When the drive shaft to drive the rotor to rotate, the action of the return ring and the link such that the plunger in the plunger bore for reciprocation of the rotor, to achieve variation sealed volumes. Each revolution of the rotor double radial pump, each plunger reciprocates once, to complete a process of suction and discharge of oil. Hydraulic oil through internal channels with the flow axis radial piston pump suction by mouth, into the piston chamber in the rotor to later this week, when the rotor to the radial half weeks after the booster pump, with flow from the shaft halves high pressure area is discharged through the exhaust port, the supply of the actuator. * On both sides of the pump body with large and small control plunger pump pressure oil through the oil passages on three rows of radial pump, all the way into the small control piston, the other way through the variable mechanism (valve) to produce a voltage drop After re-entering the large control piston cavity. When the pump can be controlled by adjusting the variable mechanism, so that the size of the control piston moving the stator in the horizontal direction, to change the size of eccentricity, so as to achieve the purpose of the variable. Vibration and noise occur simultaneously. They not only cause harm to the operator of the machine, but also pollute the environment. (1) mechanical vibration and noise as the pump shaft and motor shaft misalignment or top dead, bearing the rotating shaft coupling damage, breakage and elastic pad mounting bolts loose will produce noise. For high-speed operation, or transmission of large energy pumps, to regularly check, record the amplitude, frequency, and the noise of the components. As the rotational frequency and the natural frequency of the pump pressure valve are the same, will cause resonance, the pump speed can be changed to eliminate resonance. Noise inlet duct (2) pipeline flow generated too small, into the oil filter flow capacity is too small or clogged air sucked into the pipeline, oil excluded too high, too low suction oil shortage and high pressure piping produced fluid strike, are generated noise. Therefore, the tank must be properly designed, the correct choice of filters, tubing and directional valve.
