Description:

Rexroth Hydraulic Pump A10VSO18DFR/31R-PPA12N00 is a high-performance axial piston variable displacement pump produced by Bosch Rexroth of Germany. The pump adopts a swash plate design and is suitable for open-loop hydrostatic transmission systems. Its main features include:Structure and working principle: The pump is an axial piston swash plate structure, which can achieve stepless variable displacement by adjusting the inclination angle of the swash plate. The pistons are evenly distributed in the cylinder along the circumference, and the swash plate is inclined at a certain angle to the axis of the cylinder. When the cylinder rotates, the piston reciprocates under the action of the swash plate, and oil is sucked and pressed through the oil distribution window of the oil distribution plate.Model analysis: A10VSO18DFR/31R indicates that the pump is an axial piston pump, with a cylinder radial dimension of 10mm, a variable mechanism with pressure compensation, a swash plate mechanism, an open circuit, a displacement of 18ml/rev, a pump head with a unloading valve, and belongs to the 31 series; PPA12N00 indicates the P+P plunger head shape, a pressure level of 12bar, a metric threaded connection, and an oil port diameter of 25mm.Technical parameters: The maximum working pressure can reach 350bar, the rated pressure is 280bar, the geometric displacement is 18cm³/rev, the maximum speed is 3300rpm, and the flow rate can reach 59l/min at the maximum displacement and rated speed.

Application areas:

Engineering machinery: such as excavators, loaders, etc., used to drive actuators such as hydraulic cylinders and hydraulic motors to achieve excavation, loading, lifting and other actions.
Industrial machinery: In metal processing machine tools, plastic machinery, papermaking machinery and other equipment, it provides power for the hydraulic system to meet the high precision and high efficiency requirements of the equipment.
Maritime ships: used for hydraulic equipment such as ship steering gear, anchor winch, winch, etc. to ensure the safety and reliability of ship navigation and operation.
Mining machinery: in the process of mining, mineral processing, etc., it provides power for the hydraulic system of crusher, screening machine and other equipment.
Agricultural machinery: such as combine harvesters, tractors, etc., used to drive hydraulic suspension systems, hydraulic steering systems, etc.

Advantages:

High efficiency: The flow rate is proportional to the drive speed and displacement, and can be adjusted by adjusting the inclination of the swash plate to achieve stepless variables, thereby improving the overall efficiency of the system.
Low noise: The use of advanced design and manufacturing technology effectively reduces the operating noise and provides a more comfortable working environment for operators.
Long life: It has excellent suction performance, can effectively reduce cavitation and increase the service life of the pump. At the same time, its compact structure and high processing precision further enhance its durability.
High power/weight ratio: While ensuring high performance, it has a high power/weight ratio and is easy to install and use.
Multiple control forms: Provide a wide range of controllers and active products to meet the needs of different application scenarios. The control response time is short and can quickly adapt to changes in system pressure and flow.
Versatility: The mounting flange adopts ISO standard, and the flange connection conforms to the SAE metric system, which has good versatility and interchangeability. The through-shaft structure design allows it to be used in multi-circuit systems and is easy to combine with other hydraulic components.
Strong adaptability: Suitable for a variety of media such as hydraulic oils, lubricating oils and process fluids. High protection level, can adapt to different working environments.
