K3V hydraulic pump

The K3V hydraulic pump is a variable - displacement axial - piston pump of swash - plate design produced by Kawasaki. Here is an introduction to it:

Structural features

1. Axial - piston swash - plate structure: The piston is arranged axially with respect to the drive shaft, and the swash - plate angle can be adjusted to change the displacement of the pump. It consists of main components such as a cylinder block, pistons, a swash - plate, a valve plate, and a drive shaft.

2. Dual - pump tandem design: It often adopts a dual - pump tandem structure, and can be equipped with a gear pump in series for pilot control. This design can meet the requirements of different working conditions and improve the overall performance of the hydraulic system.

Working principle

The drive shaft drives the cylinder block to rotate. As the cylinder block rotates, the pistons, which are connected to the swash - plate through slippers, reciprocate in the cylinder bores. When the swash - plate angle changes, the stroke of the pistons changes, thereby changing the volume of oil sucked and discharged by the pump, achieving variable - displacement control.

Technical characteristics

1. High power density: It can provide high - power output in a compact structure, suitable for applications where space is limited but high power is required.

2. High efficiency: It has high - energy conversion efficiency, which can effectively convert input power into hydraulic power output, reducing energy loss.

3. Wide range of control options: It offers a variety of control methods, such as negative - flow control, positive - flow control, power control, and two - stage - flow control, which can meet the different working requirements of various equipment.

4. High suction capability: It has strong suction ability, which can ensure the stable supply of hydraulic oil and the reliable operation of the pump even under difficult oil - suction conditions.

5. Good reliability and durability: Made of high - quality materials and advanced manufacturing processes, it has good reliability and long service life, which can withstand the harsh working environment and long - term operation of construction machinery.

Application scenarios

K3V hydraulic pump is widely used in various mobile machinery and equipment, such as excavators, wheel loaders, crawler drills, pile drivers, cranes, and concrete pumps. It is also used in industrial machinery such as crushers and presses, as well as in marine and offshore equipment and mining equipment to provide reliable hydraulic power.
