The main principle of choosing hydraulic pump is the type of main equipment.The main factors to be considered in choosing hydraulic pump are structural form, working pressure, flow rate, speed, efficiency, quantitative or variable, variable mode, life span, type of prime mover, noise, pressure ...
Structure composition and working principle of hydraulic driven downhole twin-screw pump are firstly introduced, and the calculation method of work and structure parameters when downhole twin-screw pump and turbine motor operate is given, and dynamic measuring process when ground power pump, turbine ...
Hydraulic oil forms a certain pressure by vane pump and enters the lower end of the hydraulic cylinder through oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve and balance valve. The piston of the hydraulic cylinder moves upward, lifts heavy obj...
The hydraulic pump unit is a water-operated ejector, which uses a motor-driven single-stage recirculating lift pump, and a covered water seal and air separation tank. From: Turbines, Generators and Associated Plant (Third Edition), 1991

Multi-Cylinder Hydraulic Cone Crusher Working Principle The multi-cylinder hydraulic cone crusher machine rotation of the motor is transmitted to the eccentric sleeve through the pulley, transmission shaft, and bevel gear so that the eccentric sleeve rotates around the ...
Fig. 3. The working principle of plunger pump. The movement of crosshead and piston is the same, so the movement of B in the center of crosshead pin can be indicated the movement of piston. We can see fromFig. 3, plunger displacement formula:(1)s≈r(1∓cosφ±λ2sin2φ) ...
2.1. Working Principles of System The hydraulic loading system is used to simulate rolling force on the test bearing. The pressure range is 0–20 MPa and it is equivalent to 0–90 tons load. This system consists of a fuel tank, motor, axial piston pump, proportional valve, accumulator, co...
