Plunger hydraulic pumpsfor milling machines, shipbuilding industry, injection molding machines, press machines, and other series of equipment (swashplate quantitative piston pumps, swashplate variable piston pumps)
Ships, snow sweepers, Garbage truck, excavators, crawler running mechanisms, construction machinery, road rollers, drills, roadheader, pavers.
The working principle of the oblique axis quantitative piston pump (oblique axis variable displacement piston pump) is that the external power drives the pump shaft to rotate - generating hydraulic pressure--
Control through multiple valves - drive the actuator transmission mechanism. The principle is mechanical energy - hydraulic energy - mechanical energy,
Mainly to humanize the control of energy conversion and meet the special needs of the working mechanism. The working principle of hydraulic motors is exactly the opposite,
Absorb and convert the energy provided by the hydraulic pump into output torque and speed.
Operational principle This series of piston type circulating hydraulic pumps mainly convert mechanical energy into hydraulic energy, and then convert it into mechanical energy, etc,
Its purpose is to meet the needs of work production and control methods, as well as the amplification and reduction of energy.
The plunger hydraulic pump has strong axial and radial loads and output power. The working mechanism is driven by an engine plunger pump-
-Control valve - hydraulic actuator. The forward and reverse control of the closed system circuit is achieved through the mechanical manual directional valve or electric proportion of the hydraulic pump itself
Controlled servo directional valve. For an open system, the flow direction is directly controlled by a directional control valve to achieve the goal of changing direction.
The working principle of a hydraulic motor is exactly the opposite, absorbing and converting the energy provided by the hydraulic pump into output torque and speed. Hydraulic motor
Equipped with infinitely variable speed and adjustable torque, the output torque is proportional to the pressure, and the output speed is proportional to the flow rate,
Inversely proportional to its displacement. It has multiple flexible and reliable control methods and feedback regulation functions.
