The Rexroth A4VG series hydraulic pump is a well - known and widely used component in hydraulic systems. It is designed to convert mechanical power into hydraulic energy with high efficiency and precision.
2. Performance Parameters
Flow Rate
The flow rate of the A4VG pump can vary depending on the model and operating conditions. It is typically measured in liters per minute (L/min). For example, different displacement settings of the pump can lead to flow rates ranging from a few liters per minute to several hundred liters per minute. The flow rate is an important factor as it determines the speed at which hydraulic actuators (such as cylinders or motors) can operate.
Pressure Rating
These pumps are capable of withstanding and generating high pressures. The maximum pressure rating can reach up to several hundred bar. For instance, in some heavy - duty applications, the pump can operate at pressures around 350 - 400 bar. The pressure - handling ability allows the pump to provide the necessary force to drive hydraulic machinery, such as in construction equipment or industrial presses.
Speed Range
The A4VG series has a defined speed range within which it operates optimally. The rotational speed is usually measured in revolutions per minute (rpm). The pump can generally operate within a speed range from a few hundred rpm to a maximum speed that might be around 3000 - 4000 rpm, depending on the specific model and its design characteristics.
3. Displacement
The displacement of the A4VG hydraulic pump is an important specification. It represents the volume of fluid that the pump can displace per revolution of its input shaft. Displacement values can vary across different models of the series. It is usually measured in cubic centimeters per revolution (cc/rev). This parameter directly affects the flow rate of the pump, as the flow rate is the product of the displacement and the rotational speed of the pump (Q = V × n, where Q is the flow rate, V is the displacement, and n is the rotational speed).
