Single-action rod-type radial piston shown in Figure 4-6, the link motor map, axial flow diagram of the hydraulic motor, the Pentagon radial motor assembly animation shows the single acting type radial piston rod operating principle Imported hydraulic refinement, it was a five-pointed star-shaped appearance. The motor housing 1 by the crankshaft 6, with the flow axis 5, 3 rod, piston 2, and eccentric four other parts. Advantages: simple structure, reliable work. Disadvantages: bulky, heavy import pump maintenance, transfer torque ripple, one of the low-speed hydraulic motor is less stable parallel circuits: two hydraulic motors through their respective control valve and control valve can be operated simultaneously with a single operation , respectively, can be speed, and the speed can be achieved basically unchanged. But throttle speed pump import Specialist, power loss is large, the two motors have their work pressure, the speed depends on the flow of their passes. Two parallel circuit of hydraulic motors: two hydraulic motor shaft rigidly coupled together, when the valve 3 in the left position of the hydraulic pump, motor 2 only with an idling motor, an output torque of the motor only. If an output torque of the motor can not meet the load requirements, the valve 3 placed in the right place, at this time, although the increase in torque, but the speed should be reduced accordingly. Pump import agents, crystal create a hydraulic (certified), the hydraulic pump by Jinan Jing Chong hydraulic machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the crystal to create a hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal to create a better future for the hydraulic.
