Sany Excavator Pump KAWASAKI K3V63DP-1L8P-9S09
KAWASAKI K3V63DP-1L8P-9S09 is an inclined shaft variable displacement piston pump, commonly known as a twin pump or through shaft drive pump. Its core features are compact structure, high power density, good reliability, and allowing additional hydraulic pumps to be connected in series through a shaft structure to provide power for complex multi circuit hydraulic systems.
Main features and advantages
Dual power control (DP control):
Engine protection: core advantage. By sensing system pressure, the pump can operate on two different power curves (for example, using a high power curve at low pressure and automatically switching to a low power curve at high pressure), ensuring that the power absorbed by the pump always does not exceed the available power of the engine and avoiding engine overload and stalling.
Efficient and energy-saving: keep the engine working in the high-efficiency range, saving fuel.
Through axis drive design:
Modularization: The rear end of the pump can be connected in series with additional gear pumps, plunger pumps, etc., providing power for auxiliary functions such as steering, fans, and walking, simplifying the design of the transmission system.
High power density and durability:
Adopting an inclined axis design, the structure is sturdy, the bearing load capacity is strong, it can withstand continuous high-pressure impact, and the service life is long.
Suitable for harsh working environments.
High voltage rating:
The rated working pressure of this series of pumps is usually very high, with a continuous working pressure of 34.3 MPa (350 kgf/cm ²) or higher, and a higher peak pressure, which can meet the needs of heavy equipment.
