The Rexroth A10VO28 hydraulic pump is specifically designed for medium-sized excavators like the Caterpillar 345B.
It belongs to the A10VO series of axial piston pumps manufactured by Bosch Rexroth, a leading name in hydraulic technologies. The A10VO series is known for its durability, high efficiency, and advanced control options, making it a popular choice among construction and industrial equipment manufacturers.
The A10VO28 pump is characterized by its displacement of 28 cm³/rev, which determines the flow rate of hydraulic fluid it can deliver. This pump is designed to handle the demanding requirements of heavy-duty applications, providing the necessary power and performance to drive the hydraulic system of the Caterpillar 345B.
One of the key features of the A10VO28 pump is its axial piston design. It consists of a rotating cylinder block with several pistons arranged in a circular pattern. These pistons are driven by a swashplate mechanism that converts the rotational motion of the input shaft into linear motion, creating hydraulic pressure. This design allows for efficient and precise control of the fluid flow, ensuring smooth operation of the excavator's various hydraulic functions.
The A10VO28 pump also incorporates advanced technologies to enhance its performance and reliability.
It includes a pressure compensator that automatically adjusts the flow rate to maintain a constant pressure, even under varying loads. This feature improves efficiency and prevents excessive pressure buildup, protecting the hydraulic system from potential damage.
Additionally, the pump is equipped with a hydraulic servo control system that enables precise control of the pump's displacement and flow rate. This control system allows the operator to adjust the excavator's performance according to the specific task at hand, optimizing productivity and reducing fuel consumption.
The A10VO28 pump is designed to withstand harsh operating conditions. It features high-quality materials and robust construction, ensuring durability and long service life. The pump is also engineered to operate smoothly at high pressures and temperatures, making it suitable for heavy-duty applications in demanding environments.
