Type7: It is a variable - displacement axial - piston pump of the K3V series from Kawasaki. It adopts a swash - plate design, which is suitable for mobile applications such as excavators.
Displacement: The displacement is 63
cm
3
/rev8. This means that the pump discharges 63 cubic centimeters of oil per revolution.
Pressure7
Rated Pressure: It is 34.3 MPa, which is the pressure at which the pump can operate stably and continuously under normal working conditions.
Peak Pressure: It can reach 39.2 MPa, which is the maximum pressure that the pump can withstand for a short time under special circumstances.
Speed7: The maximum self - priming speed is 2650 rpm, which is the maximum rotational speed for the pump to self - prime.
Control Mode: The K3V series pumps have a variety of control modes and can respond to mechanical, hydraulic, or electrical inputs, providing flexible control methods for the hydraulic system of the excavator.
Structure7: It includes single - pump and tandem - pump structures. The tandem - pump structure can meet the needs of different working conditions and improve the working efficiency of the hydraulic system.
Material: The pump body is usually made of alloy steel, which has high strength and good wear - resistance to ensure the durability of the pump under high - pressure and high - speed working conditions.
