What is China rexroth axial piston pump?
Rexroth axial piston pump is an important linde hydraulic pump component. In 1966, China hydraulic pump manufacturer successfully designed the CY14-1 axial piston pump after integrating the characteristics of foreign swash plate piston pumps. In the following thirty years, after four major improvements, the pump has been significantly improved in terms of performance, size, and reliability.
After entering the 1990s, Germany’s Bosch Rexroth Company further promoted the technological innovation of axial piston pumps and developed the A4V pump. The characteristic of this pump is that its plunger and the transmission shaft form an intersection angle.
During operation, the centrifugal force contributes to the return stroke of the plunger, reducing the diameter of the distribution plate and the linear speed of the cylinder distribution surface. En même temps, the spherical flow distribution design can effectively compensate for the overturning moment caused by axial unbalanced load on the cylinder, so it is widely used in modern industrial fields.
Advantages of Rexroth axial piston pumps:
High rated pressure and high efficiency: Well-designed and high rated pressure, it can meet the needs of high-pressure working environments. En même temps, its volumetric efficiency can reach about 95%, and the total efficiency can also be maintained at about 90%, showing excellent work efficiency.
Convenient variables and various forms: By adjusting the angle of the swash plate, the Rexroth axial piston pump can easily realize stepless adjustment of the output flow to meet the needs of different working scenarios.
Compact structure and light weight: The design of the axial piston pump makes it compact in structure and light in weight per unit power, which helps to reduce the overall weight of the equipment and improve the portability and flexibility of the equipment.
Long service life: Since the main parts are subject to compressive stress, the material strength properties are fully utilized, giving the Rexroth axial piston pump a long service life.
Low noise level: Rexroth axial piston pumps operate at a low noise level, which helps improve the working environment and reduce operator fatigue.
Modular design: This design makes the installation, maintenance and replacement of the pump more convenient, improving the maintainability and reliability of the equipment.
Short response time: Rexroth axial piston pump has a short response time, which can quickly respond to system needs and ensure the stable operation of the hydraulic system.
Rexroth axial piston pumps are mainly used in the following areas:
Machine tools and metallurgical equipment: Rexroth axial piston pumps are often used in the hydraulic transmission systems of machine tools and metallurgical equipment due to their high-pressure and large-flow characteristics. In these equipment, axial piston pumps can stably and efficiently provide the required hydraulic power to ensure the normal operation of the equipment.
Construction Machinery and Construction Equipment: In construction and mining equipment, hydraulic pumps play a vital role. Rexroth axial piston pumps can adapt to the working needs of these equipment in complex environments and provide stable and long-lasting hydraulic power support.
Marine and Offshore Engineering: Axial piston pumps are also widely used in marine and offshore applications such as ship steering systems, deck machinery and hydraulic winches. They provide the necessary power and control in these applications to ensure the proper operation of ships and offshore engineering equipment.
Oil and Gas Industry: In the oil and gas industry, Rexroth axial piston pumps are used in drilling rigs, wellhead control systems, hydraulic fracturing operations, and offshore platform equipment. These pumps deliver high-pressure fluid power to meet the needs of oil and gas extraction, production and hydraulic control systems.
Power generation industry: In power generation applications, Rexroth axial piston pumps also play an important role. They are used in turbine control of hydroelectric power plants, dam gate operations and other hydraulic systems to ensure stable operation of power generation equipment.
