Radial piston pump works: the drive torque from the drive shaft to pass through the cross-coupling hydraulic cylinder star rotor variable pump refinement, scheduled from other lateral forces. Turn on mounted with the flow axis. Located in the rotor radially arranged piston variable pump maintenance, by hydrostatic balance slipper close to the eccentric line 程定子. Slipper piston and ball joints connected by retainer locks. Two retaining ring on the line card will Slipper 程定子. Axial piston pump is a reciprocating direction of the central axis of the piston and the cylinder parallel piston or plunger. Variable hydraulic variable displacement pump and variable mechanism motor pump has a wide variety of variables care, which can be divided into two categories: the first category divided according to type manually operated, motorized, electric, hydraulic and electro-hydraulic proportional control control, signal control variables are applied; the second by adjusting the way to distinguish, which automatically controls the pump (motor) basic parameters (including pressure, flow, power, etc.) change according to certain rules, such as constant power, constant pressure, constant flow. Variable pump maintenance | crystal create a hydraulic (certified) | Variable pump from 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.
