Product Description The A7VO series is a variable - displacement piston pump with various variable - displacement modes. It is suitable for various regulating and control devices. It has a robust and compact bearing system, ensuring a long service life. It has control modes such as LR power control, DR pressure control, HD hydraulic control, and EP electric control. Working PrincipleThe A7VO pump adopts a bent - axis structure. The bent axis drives the plunger to move back and forth in the cylinder block to achieve the suction and discharge of hydraulic oil. By adjusting the angle of the bent axis, the stroke and speed of the plunger can be adjusted, thereby changing the displacement and output pressure of the pump. Performance Characteristics- High - pressure output: It can provide high - pressure hydraulic oil output, suitable for applications requiring high - pressure hydraulic systems.- Efficient and energy - saving: Through optimized design and manufacturing processes, it has high transmission efficiency, which can reduce energy loss and improve system efficiency.- High reliability: High - quality materials and manufacturing processes are used to ensure high reliability and durability.- Easy to maintain: The design takes into account maintenance needs, facilitating daily maintenance. It is widely used in various industrial fields, such as machine tools, plastic machinery, textile machinery, paper - making machinery, and aluminum extrusion machines. In the field of construction machinery, it is used in concrete pump trucks, excavators, loaders, and cranes. It also has applications in metallurgical equipment like steel - making furnaces and rolling mills, and in the shipbuilding industry for driving equipment such as servos, windlasses, and cargo winches. Technical ParametersThe nominal pressure is 350 bar, and the maximum pressure is 400 bar. The displacement ranges from 28 to 500. The flow is proportional to the rotational speed and displacement of the pump, and it can be adjusted steplessly from the maximum flow (qvmax) to zero (qvmin = 0). The application areas of the A7VO series pumps:Machine ToolsIn the field of machine tools, the A7VO series pumps are used to power various components. They drive the spindle to achieve high - speed rotation, provide power for the tool holder to realize precise tool feeding and positioning, and also actuate the workbench for smooth movement and accurate positioning. This ensures the high - precision machining of workpieces, improving the quality and efficiency of machining. Plastic MachineryFor plastic machinery such as injection molding machines, the A7VO series pumps supply hydraulic pressure for the injection unit to complete the injection process, drive the mold opening and closing mechanism to realize the demolding of products, and provide power for the screw rotation and plasticizing system. In the case of extruders, they provide power for the extrusion process to ensure the stable output of plastic products. Construction MachineryIn construction machinery like concrete pump trucks, the A7VO series pumps power the hydraulic cylinders of the boom to achieve the lifting and swinging of the boom, and supply power to the hydraulic motors of the pump body to realize the conveying of concrete. For excavators, they drive the hydraulic cylinders of the boom, arm, and bucket to complete digging and loading operations, and also provide power for the rotation of the chassis. In loaders, they power the hydraulic cylinders of the bucket and boom for loading and unloading operations, and supply power to the hydraulic motors of the wheels for driving. Cranes rely on these pumps to provide power for the lifting and slewing of the boom, as well as the hoisting of the hook. Metallurgical EquipmentIn metallurgical equipment such as steel - making furnaces, the A7VO series pumps are used in the hydraulic systems of the charging and tapping mechanisms to provide the necessary power. In rolling mills, they drive the hydraulic cylinders of the roll adjustment mechanism to adjust the roll gap, and supply power to the hydraulic motors of the conveyor rollers to transport the steel materials. Shipbuilding IndustryIn the shipbuilding industry, the A7VO series pumps are used to drive the servo - actuators of the rudder system to achieve the steering of the ship, provide power for the windlass to realize the lifting and lowering of the anchor, and supply hydraulic pressure for the cargo winch to complete the loading and unloading of goods.
