Model Numbers: 20R - 6569/20R6569 and 3073063/307 - 3063
Applicable Equipment: 422F, 434F, 426F Backhoe Loaders
Function: As a hydraulic piston pump, it is a crucial component of the backhoe loader's hydraulic system. It is responsible for pressurizing and supplying hydraulic fluid to various hydraulic actuators such as the loader arms, backhoe arms, and bucket cylinders, enabling the precise control and movement of the equipment's working components.
2. Performance Specifications
2.1 Flow Rate
Rated Flow: The rated flow rate of this hydraulic pump is an important parameter that determines the speed of hydraulic operations. It is typically [X] liters per minute (L/min). This value may vary depending on the rotational speed of the pump and the specific operating conditions. The rated flow rate directly impacts the speed at which the backhoe loader's hydraulic actuators can move. For example, a higher flow rate allows for faster movement of the loader and backhoe arms.
Variable Flow Capability: The pump may have a variable flow control mechanism. The minimum flow rate might be [Y] L/min and the maximum could reach up to [Z] L/min. This variability allows the operator to adjust the speed and power of the hydraulic functions according to the work requirements. For instance, a lower flow rate can be used for precise digging or loading operations, while a higher flow rate is needed for more rapid movements during transportation or repositioning of the equipment.
2.2 Pressure Ratings
Rated Pressure: The rated working pressure of the pump is [P1] megapascals (MPa). This is the pressure at which the pump is designed to operate continuously under normal working conditions. It ensures the efficient transfer of hydraulic energy to the backhoe loader's hydraulic components such as cylinders and motors.
Peak Pressure: The pump can withstand a peak pressure of [P2] MPa for short - term, high - load situations. However, continuous operation at or near the peak pressure may lead to reduced service life and potential damage to the pump and other hydraulic system components.
