HPV35 Charge Pump

 HPV35 Charge Pump Overview

The HPV35 Charge Pump functions as an important low-pressure oil supply unit in hydraulic systems. It is installed on the HPV35 main hydraulic pump and is designed to provide stable charge flow and charge pressure for the main pump. The pump operates based on the principle of volumetric hydraulic transmission. Through the meshing rotation of external gears, the volume of sealed working chambers changes, enabling continuous suction and discharge of hydraulic oil.

The charge pump helps maintain favorable suction conditions for the main pump, supplies oil for hydraulic control circuits, and provides necessary lubrication and cooling for key internal components. When the hydraulic system operates under long-term heavy-load conditions, the charge pump ensures a stable charge pressure supply, helping prevent cavitation and insufficient oil supply. This effectively reduces wear and potential damage to critical components inside the main pump, such as pistons, bearings, and valve plates, ensuring stable and efficient operation of the entire hydraulic system, extending equipment service life, and reducing maintenance costs.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
