PV30 is a new type of energy-saving hydraulic system with distinct advantages over conventional hydraulic systems.
Energy Saving
It achieves remarkable energy and power savings during long-term pressure-holding operations, cutting power consumption by 30%–60% compared with standard hydraulic units.
When the hydraulic chuck and cylinder are in pressure-holding mode (non-operating state), the motor runs at a low speed of 450 rpm to minimize power consumption. When the hydraulic chuck and cylinder are activated, the motor automatically accelerates to 1450 rpm.
Space Saving
The oil tank capacity is only 30L , and the permanent magnet motor is half the size of an induction asynchronous motor. This reduces the overall installation space of the hydraulic station by 60% compared with standard hydraulic setups.
Low Oil Temperature & Low Noise
During operation, the oil temperature stays close to the ambient temperature. At low motor speeds, the entire hydraulic system operates with ultra-low noise.
For example, a 2.2KW motor hydraulic system on a CNC lathe can be directly replaced with the 1.5KW PV30 energy-saving hydraulic system for universal compatibility and greater power efficiency.
Features:
Direct replacement for traditional hydraulic units.
Uses an electromagnetic directional valve to switch the operating direction of the cylinder.
Enables cylinder speed (flow rate) and load (pressure) control via a dedicated controller (no need for separate speed control valves or pressure control valves).
The controller automatically switches between flow control mode and pressure control mode based on real-time load conditions.
The system can output external signals (open-collector signals) in series according to flow and pressure commands, which can be used to switch electromagnetic directional valves and other components in a command-series configuration.
