K3V Hydraulic Pump

K3V hydraulic pump is a high-performance swash plate axial piston variable displacement pump produced by Kawasaki Company in Korea, widely used in the field of construction machinery, with the characteristics of load-sensitive, stable pressure, remote control variable pressure unloading and power control. The following is a detailed introduction of K3V hydraulic pump:

First, Product Features

1.Load-sensitive and pressure stabilization: K3V hydraulic pump can automatically adjust the output pressure according to the system load and keep the pressure stable, so as to improve the efficiency of the system.

2. Remote control of pressure change and unloading: Support remote control of pressure change and unloading function, which is convenient for users to adjust the working status of the pump according to the actual needs.

3. Controllable power: through advanced control technology, it realizes precise control of pump output power and prevents engine overload.

4. High efficiency and energy saving: adopting advanced hydraulic technology, it is characterized by high efficiency and energy saving, which can save a lot of energy cost for users.

5. Stable and reliable: after strict quality control, it has high stability and reliability, and can work continuously for a long time without failure.

Second, technical parameters

1.Displacement range: provide a variety of displacement options, such as K3V63, K3V112, K3V140, K3V180, K3V280, etc., covering 63cc/rev to 280cc/rev, to meet the needs of different applications.

2. Pressure Rating:

Rated Pressure: 34.3MPa (350kgf/cm²).

Instantaneous high pressure: 39.2MPa (400kgf/cm²).

3. Speed range:

Self-priming high RPM: Self-priming high RPM between 1600r/min and 2650r/min depending on displacement.

High speed: 2000r/min to 3250r/min depending on the displacement.

Third, Application Scenarios

1. Hydraulic excavators: such as Sumitomo, Hyundai, Kato, Kamsteel, Hitachi and other series of excavators.

2. Concrete Pump Trucks: Provide reliable power source for concrete pump trucks.

3. Complex terrain cranes: adapted to lifting operations in complex terrain.

4. derrick support drive equipment: provide stable power for the drive of derrick support.

5. Crusher, Crawler Driller, Crawler Crane: to meet the needs of crushing, drilling and lifting in the field of mining and construction.

Fourth, control mode

K3V hydraulic pumps support a variety of control modes to meet the needs of different users:

1. total power control: to realize the actuator's light-load high-speed and heavy-load low-speed action, which can ensure that the hydraulic pump makes full use of the engine power and prevent the engine from being overloaded.

2. Negative flow control: minimize overflow power loss and system heating, improve system efficiency.

3. power conversion control: change the input current size according to the load, adjust the output power of the hydraulic pump, improve efficiency and save engine power.

Fifth, maintenance and maintenance recommendations

1.anti-rust treatment: after the user buys back the pump, if it is not used in time, it should be injected with anti-rust oil inside, and the exposed surface should be coated with anti-rust grease, and then cover the dust cap of the oil port.

2. Oil temperature control: keep the oil temperature within 10-60℃, especially avoid high temperature continuous operation, otherwise the life of the pump will be greatly shortened.

3. oil level check: set oil level meter in the oil tank for frequent observation and oil replenishment to maintain normal oil level.

4. Oil performance test: check the performance of oil regularly, even less than the specified requirements should be replaced in a timely manner and clean the oil tank.

5. Filter cleaning: the oil filter should be cleaned frequently to ensure that the oil inhalation is smooth.

6. Screw checking: After the pump has been working for some time, due to vibration, the mounting screws or inlet/outlet valve screws may be loosened, so it is necessary to pay attention to check and tighten them to prevent them from loosening.
