The hydraulic main pump used in the Hitachi ZX140W-3, ZX170W-3, Bei den Modellen ZX210W-3 und ZX210W-3 handelt es sich um eine Axialkolbenpumpe mit variabler Verdrängung.
It is designed to provide the necessary hydraulic power required for the machine’s operation, including the movement of the boom, Arm, Eimer, und andere hydraulische Funktionen.
The pump operates using a hydraulic system that utilizes oil flow and pressure to transfer power to different hydraulic actuators. It converts mechanical energy from the engine into hydraulic energy, enabling the excavator to perform various tasks efficiently.
The main pump has a variable displacement feature, which means it can adjust the oil flow according to the specific requirements of the operation. This allows for precise control of the machine’s movements, enhancing productivity and accuracy during excavation or material handling tasks.
The hydraulic main pump has a maximum pressure rating of around 35 MPA (mega pascals). This high-pressure capability ensures that the excavator can generate sufficient force for heavy-duty digging and lifting operations. The pump’s pressure rating also contributes to its ability to handle tough working conditions and challenging terrains.
In Bezug auf die Durchflusskapazität, the hydraulic main pump delivers a variable oil flow rate depending on the operation’s demands.
It can provide a maximum flow rate of approximately 240 Liter pro Minute (l/min) in the ZX140W-3 model, 300 l/min in the ZX170W-3, Und 380 l/min in the ZX210W-3. The varying flow rates cater to different applications and enable the machine to adapt to the workload efficiently.
Um Zuverlässigkeit und Langlebigkeit zu gewährleisten, the hydraulic main pump is constructed with high-quality materials and undergoes rigorous testing during the manufacturing process. The pump features robust internal components, such as precision-machined pistons, Zylinderblöcke, und Ventilplatten, designed to withstand high-pressure conditions and continuous use.
Zusätzlich, the pump incorporates advanced hydraulic technologies and innovations, including optimized oil flow paths, efficient filtration systems, and noise reduction measures. These features contribute to smoother operation, reduzierter Energieverbrauch, verbesserte Kraftstoffeffizienz, and minimized noise levels during machine operation.
Maintenance of the hydraulic main pump is crucial for its longevity and performance. Regelmäßige Inspektionen, proper lubrication, and adherence to recommended service intervals are necessary to keep the pump in optimal condition. Hitachi provides detailed maintenance guidelines and support to ensure the longevity of their hydraulic systems.
