K3V hydraulic pump

K3V hydraulic pump is a high-performance axial piston pump launched by Kawasaki Heavy Industries, which is widely used in the fields of construction machinery, shipbuilding, industrial equipment, etc. The following is an analysis of the technical characteristics, application scenarios, performance advantages and maintenance points:

First, technical characteristics

1、Swash plate axial piston structure

K3V series adopts swash plate axial plunger design, the plunger reciprocates in the cylinder body, and at the same time drives the cylinder body to rotate, realizing high efficient hydraulic energy conversion. The oil distribution plate is fixed and immobile, and the pumping task is accomplished through the synergistic action of cam and plunger spring, with compact structure and stable operation.

2、Variable adjustment and high efficiency

It supports stepless adjustment of displacement, and the output speed is determined by the flow rate and displacement of the pump, which is suitable for different working conditions. Plunger pumps are complex but can produce higher pressure, compared with gear pumps in high-pressure working conditions with better performance.

3、High pressure and wide speed range

Rated pressure: 34.3MPa, peak pressure: 39.2MPa, to meet the needs of a wide range of working environments from low to high pressure.

Speed range: 2000-2650r/min (different models), users can adjust the speed according to the actual working conditions to optimize work efficiency.

4、Modularization and compatibility design

Supports duplex pump structure, interchangeable with other brands (such as Tongmyung) hydraulic pumps, reducing maintenance costs.

Provide a variety of controller types to meet the needs of different hydraulic systems.

Second, K3V hydraulic pump application scenario

1、Construction machinery

Excavator: as the main pump output main pressure oil, drive walking, slewing and other actions to enhance the power and efficiency of the equipment.

Cranes and piling rigs: provide stable hydraulic power to adapt to heavy-duty working conditions.

2、Ships and marine engineering

Deck machinery: such as anchor cable machine, winch, etc., through the K3V pump drive to realize efficient operation.

Hydrostatic transmission system: K8V series closed-loop pumps are used in off-highway machinery to improve controllability and efficiency.

3、Industrial equipment

Injection molding machine, die-casting machine: to provide high pressure hydraulic power to achieve mold opening and closing, injection and other actions.

Metallurgical equipment: such as rolling mills, continuous casting machines, through precise hydraulic control to improve production accuracy.

Third, performance advantages

1、High efficiency and energy saving

Adopting advanced hydraulic technology to reduce energy consumption and save operating costs.

2、High reliability and long life

Through strict quality control, it has high stability and durability, and reduces downtime.

3、Low noise and easy maintenance

Optimized design reduces operating noise, simple structure and easy maintenance.

4、Wide adaptability

Supporting a variety of drive modes, such as motor, hydraulic motor, pneumatic motor, etc., suitable for different application scenarios.

Fourth, maintenance points

1、Oil management

Viscosity requirements: select the appropriate viscosity hydraulic oil according to the working temperature (such as 5-1600mm²/s).

Cleanliness control: keep the hydraulic oil clean, replace the filter element regularly to prevent oil pollution.

2、Component inspection and replacement

Plunger and cylinder: regularly check the plunger gap and cylinder wear, timely adjustment or replacement.

Oil distribution disk and bearing: check the sealing and bearing clearance to ensure efficient operation.
