The Rexroth A2FO series hydraulic pump is a key component in hydraulic systems. It is designed to provide reliable and efficient hydraulic power for a wide range of applications.
2. Basic Design and Construction
The pump features a robust design with high - quality materials to ensure durability and long - term performance. It typically consists of a housing that encloses the internal working parts such as the pistons, cylinder block, and valve plate. The housing is usually made of cast iron or other strong alloys to withstand the pressures and forces involved in hydraulic operations.
3. Performance Characteristics
Flow Rate
The flow rate of the A2FO series pump varies depending on the model and operating conditions. It is measured in liters per minute (L/min). The pump's displacement per revolution and its rotational speed determine the flow rate. For example, a particular model with a displacement of 50 cm³/rev running at 1500 revolutions per minute (rpm) would have a flow rate of 50×1500/1000 = 75 L/min. This flow rate is crucial for supplying the correct amount of hydraulic fluid to actuators like hydraulic cylinders or motors at the desired speed.
Pressure Ratings
These pumps are capable of operating under high - pressure conditions. The maximum pressure that the A2FO series can handle typically ranges from 280 bar to 400 bar, depending on the specific model. High - pressure capabilities allow the pump to be used in heavy - duty applications such as construction machinery, where significant force is required to move heavy loads.
Speed Range
The A2FO pump has a defined speed range for optimal operation. The minimum speed is usually around 500 - 800 rpm, and the maximum speed can reach up to 3000 - 3500 rpm, depending on the model. Operating the pump within this speed range helps to ensure efficient fluid transfer and reduces the risk of premature wear and damage.
4. Displacement
The displacement of the A2FO hydraulic pump is a fundamental specification. It is the volume of fluid that the pump can displace in one complete revolution of the drive shaft. The displacement values for this series typically range from 10 cm³/rev to 1000 cm³/rev. A higher displacement means that the pump can move a larger volume of fluid per revolution, which is beneficial for applications requiring a high flow rate.
