The ZX200LC-3 and ZX250-3 excavators are known for their powerful hydraulic systems, and the main pump is responsible for delivering the required hydraulic flow and pressure.
These models are equipped with a high-performance variable displacement axial piston pump, designed to meet the demanding needs of heavy-duty applications.
The main pump specifications include a rated flow rate, maximum pressure, displacement, and control mechanism. The rated flow rate refers to the volume of hydraulic fluid that the pump can deliver per minute. For the ZX200LC-3 and ZX250-3, the main pump typically has a rated flow rate of around 220 liters per minute, ensuring an ample supply of hydraulic power to operate various hydraulic functions.
In terms of maximum pressure, the hydraulic main pump of these models can typically generate pressures of up to 350 bars or 35 MPa. This high pressure allows for robust and efficient operation, enabling the excavator to handle heavy loads and tough digging conditions.
The displacement of the main pump is another important specification to consider.
It determines the volume of hydraulic fluid delivered by the pump per rotation. The ZX200LC-3 and ZX250-3 excavators generally feature a displacement of around 52 cc/rev. This displacement value directly influences the speed and power of the hydraulic system, ensuring smooth and precise control over the excavator's movements.
Control mechanisms for the hydraulic main pump can vary depending on the specific model and configuration. These models often utilize a hydraulic servo control system, which enables precise control of the pump's displacement and flow rate. The servo control system allows for responsive and accurate adjustment of hydraulic power based on the operator's input, improving overall productivity and efficiency.
Additionally, the hydraulic main pump is typically driven by the excavator's engine through a power transmission system. This ensures a continuous supply of hydraulic power, synchronized with the engine's RPM, allowing for consistent and reliable performance.
