Parker PV High-Performance, Compact Variable Pump For Machine Tool Hydraulic Systems
1, Product Overview
The PV hydraulic pump is an advanced pressure-compensated variable displacement piston pump. Its key feature is the ability to automatically adjust its output flow based on changes in system pressure to maintain a steady pressure level. This "on-demand" operating principle offers significant advantages in energy efficiency, noise reduction, and system simplification, making it one of the most widely used pump types in modern hydraulic systems.
2,Working Principle
. Start-up Phase: When the pump starts or system pressure is below the preset compensation pressure, the variable mechanism (e.g., the swashplate) is at the maximum angle, and the pump delivers flow at maximum displacement to rapidly build up system pressure.
. Compensation Phase: Once the system pressure reaches the preset compensation setting, the hydraulic pressure acts on the compensator valve spool and the variable piston. This pushes the variable mechanism (reducing the swashplate angle), thereby automatically reducing the pump's displacement.
. Pressure Maintenance Phase: When an actuator stops and only minimal flow is needed to compensate for system leakage and maintain pressure, the pump's displacement reduces to a trickle (near zero flow). At this stage, power consumption by the electric motor is very low, resulting in high energy efficiency.
3, Key Features
· High Efficiency & Energy Saving: Drastically reduces energy consumption and operating costs by only delivering the minimal flow required to maintain pressure during the holding phase.
· Stable Pressure Regulation: Automatically maintains system pressure at the set value, preventing over-pressurization and providing inherent safety.
· Reduced Heat Generation: Minimizes heat generation caused by the overflow of excess flow at high pressure, extending the service life of hydraulic fluid and system components.
· Compact & Integrated Design: The pressure compensator and variable piston are typically integrated into the pump housing, making the unit compact and reliable.
4,Typical Applications
PV pumps are ideally suited for applications requiring constant pressure systems or prolonged pressure holding, such as:
· Plastic injection molding machines
· Die-casting machines
· Machine tool hydraulic systems (e.g., clamping units)
· Presses
· Construction machinery (e.g., certain functions in excavators)
