Model Number: 708 - 3T - 00151. This specific model number is used to identify the piston main pump for the PC78MR - 6 excavator hydraulic system. It is designed to be a crucial component in the excavator's hydraulic operations.
Application: Tailor - made for the Komatsu PC78MR - 6 excavator. The pump is an integral part of the hydraulic circuit that powers the various functions of the excavator such as the boom, arm, and bucket movements.
2. Performance Specifications
Flow Rate
The flow rate of the hydraulic pump is a key parameter. It determines the speed at which the hydraulic fluid is delivered to the actuators. Although the exact flow rate for this specific model may vary depending on operating conditions and system settings, it is designed to provide a sufficient volume of fluid per unit time to enable the smooth and efficient operation of the excavator's hydraulic functions. The flow rate is typically measured in liters per minute (L/min).
Pressure Capacity
The pump is capable of generating and withstanding high hydraulic pressures. It has a specific pressure - rating range that allows it to handle the demands of the excavator's working operations. For example, it might be able to operate at pressures up to a maximum value of around 300 - 350 bar. This high - pressure capacity enables the pump to provide the necessary force to move heavy loads through the hydraulic cylinders and motors of the excavator.
Efficiency
The 708 - 3T - 00151 pump is designed to have high volumetric and mechanical efficiency. Volumetric efficiency refers to the ratio of the actual volume of fluid delivered by the pump to the theoretical volume it should deliver. A high volumetric efficiency ensures that a large portion of the fluid pumped is effectively used in the hydraulic system. Mechanical efficiency, on the other hand, takes into account the losses due to friction and other mechanical factors. High - quality construction and precision engineering aim to achieve an overall efficiency that helps in reducing energy consumption and heat generation in the hydraulic system.
