Pump and Motor Configuration:
The A7V series comprises both axial piston pumps and motors.
These components are designed to convert mechanical power into hydraulic power or vice versa. They operate based on the principle of axial piston rotation, where the pistons reciprocate within the cylinder block to generate fluid flow.
The A7V series offers a diverse range of sizes to accommodate different application requirements. The sizes are typically identified by a numerical value, such as A7V28, A7V55, A7V80, etc. Each size represents a specific displacement volume, pressure range, and performance characteristics.
Displacement and Flow Rate:
Displacement refers to the volume of fluid displaced per revolution of the pistons. It determines the flow rate and is often expressed in cubic centimeters (cc) or liters (L) per revolution. The A7V series provides various displacement options to suit different hydraulic system demands, ranging from small displacement units to larger ones capable of delivering higher flow rates.
The A7V series is designed to operate under varying pressure conditions. The pressure rating indicates the maximum working pressure that the components can handle. It is typically expressed in bars (B) or pounds per square inch (psi). The A7V series offers different pressure ratings to accommodate a wide range of hydraulic system requirements.
Rexroth A7V pumps and motors can be equipped with different control options to meet specific application needs. These include various control mechanisms like pressure compensators, load-sensing controls, and electro-hydraulic proportional controls. These control options allow for precise control of flow and pressure, enabling efficient operation and system optimization.
The A7V series offers various mounting configurations to facilitate easy installation and integration into different systems.
Common mounting options include flange mounting, foot mounting, and through-shaft mounting. The choice of mounting configuration depends on the specific application requirements and system design.
Efficiency and Performance:
Rexroth A7V series components are known for their high efficiency and performance. They are designed to minimize energy losses and maximize output power. The precise engineering, advanced materials, and manufacturing techniques employed by Rexroth contribute to the overall efficiency and performance of the A7V series.
The A7V series finds applications in a wide range of industries, including but not limited to construction, agriculture, material handling, industrial machinery, marine, and mobile equipment. These components are utilized in hydraulic systems that require reliable and efficient power transmission.
