K5V pump

The K5V pump is a hydraulic variable displacement piston pump of Kawasaki Heavy Industries Seiki series, and the following is an introduction to it:

First, structural composition

1. Pump body: It is a swash plate axial piston variable pump structure, including swash plate, return plate, oil distribution plate, cylinder block, transmission shaft, plunger, sliding shoe and other components. The transmission shaft drives the cylinder to rotate, and the plunger moves reciprocating under the action of the swash plate, and realizes oil absorption and oil discharge through the oil distribution plate.

2. Controller: that is, servo variable adjustment mechanism, which is composed of flow regulation, pressure regulation, power regulation, proportional solenoid valve, variable plunger, spring, etc., which can accurately adjust the displacement, pressure and power of the pump according to the system requirements.

Second, the basic features

1. Model: K5V series, including K5V80, K5V140, K5V160, K5V200 and other different models, with a displacement range of 80cc~200cc.

2. Structure: It is mostly a multi-cylinder structure, which is composed of two swash plate plunger pumps connected in series, and is installed with a pilot gear pump. Regulators are installed separately on the two pumps to regulate the displacement.

3.  Material: The pump body is mainly made of cast iron or carbon steel, which has high strength and wear resistance.

4. Working pressure: The working pressure range is usually 350bar~400bar, which can meet the needs of high-pressure working environment.

5. Control mode: Adopt pressure flow control, which can adjust the flow and pressure of the pump according to the actual demand.

Third, performance advantages

1. Variable adjustment: K5V pump has excellent variable adjustment performance, which can adapt to the different working conditions of the host and improve work efficiency.

2. Control accuracy: Equipped with a precise and complex variable control mechanism to achieve high-precision flow, pressure and power control.

3. Stability: Excellent performance in control stability, which can ensure the stable operation of the hydraulic system.

4. Energy saving: through the optimized variable adjustment mechanism and control mode, energy saving and consumption reduction can be realized, and operating costs can be reduced.
    

Fourth, Technical features

1. A variety of control methods: with electric proportional displacement control, constant power control, pressure cut-off control and other control methods, can adapt to the different working conditions of the host, so that the host work efficiency is higher.

2. High specific power: using new technology, the specific power is higher, and the output can be more flow or pressure under the same power.

3. Large displacement and high reliability: Under the condition of maintaining the same external installation size and regulator variable as the K3V series, the displacement is larger, and at the same time, the reliability is higher, the service life is longer, and it can meet the needs of greater torque.

Fifth, Applications

1. Construction machinery: widely used in excavators, concrete pump trucks, cranes, etc., to provide high-pressure, high-flow, high-efficiency hydraulic power for these equipment.

2. Other industries: It is also used in metallurgy, mining, ships and other industries that require high-pressure hydraulic systems.
    

Sixth, Maintenance Points

1. Daily inspection: Regularly check the oil level, oil temperature, oil quality and the wear of the seals to ensure the normal operation of the pump.

2. Cleaning and maintenance: Regularly clean the dirt and impurities in the pump body to prevent blockage and wear.
