Rexroth A4VG Series 32 Technical Data Size we service the world, HEASH is your trustworthy partner in hydraulic field. HD hydraulic control type: Pilot-controlled hydraulic control, the displacement of the pump is proportional to the pilot pressure.ДЎ. EP Electric Proportional Control: The pump displacement is proportional to the current signal of the proportional solenoid.

HW manual control: The pump displacement is proportional to the angle of the control valve handle. The following are common control methods: Safety valve on the pump to achieve system safety protection ДЄccording to the different types of control valves on the pump, the A4VG pump has various control modes. The shut-off valve on the pump limits the pressure at which the pump operates Control oil size and control signals, such as electricity, liquid, and manual signals The displacement of the pump is proportional to the difference in the control oil pressure between the two pistons of the variable piston The variable piston drives the swash plate to change the swing angle to achieve the change of the pump displacement. The control valve controls the displacement of the variable piston. The charge pump supplies the control oil. The working principle of the A4VG pump is also the same, but as a closed variable displacement piston pump, its swash plate can cross the zero position to achieve the change of the flow direction, which is a bit complicated to implement. At the same time, these 'syringes' have oil pressure and pressure. The number of syringes depends on the number of plungers.

Each plunger and the cylinder cooperate to form a syringe. Size 71 вЂ¦ 90, such as A4VTG 071 EP3**/33R, A4VTG 090 EP4**/33R.ДЇor the axial piston pump, regarding its working principle, we can think of it as several syringes working at the same time. High pressure pump for the drum drive in mobile concrete mixers High pressure pump for applications in closed circuits up to 500 bar
