Product Description:
The following is a comprehensive analysis of the advantages and characteristics of PARKER plunger pumps (represented by the PV series) and precautions for use, combined with technical parameters and application scenarios:
1. Advantages and characteristics
High-pressure and high-efficiency performance
High pressure level: Rated working pressure reaches 350bar, peak pressure exceeds 400bar, suitable for heavy hydraulic systems (such as forging equipment, ship deck machinery).
Significant energy saving: The inclined disc variable design dynamically matches the system flow demand, and the energy consumption is reduced by more than 30% compared with the fixed pump, reducing system heating.
Precision control and low pulsation
9 plunger structure: Combined with pre-compression volume technology, the flow pulsation is <±1.5%, and the output is stable (applicable to high-precision scenarios such as injection molding machine mold clamping).
Fast response: The variable response time is ≤50ms, supporting high-frequency action switching.
High reliability design
Wear-resistant structure: The design of the sliding shoe and the return plate avoids direct contact with the ball head, reduces wear, and extends the life to 1.4 times that of ordinary pumps.
Impact resistance: FEM optimized cast iron housing + reinforced bearings, resistant to vibration conditions of engineering machinery.
Intelligence and modularity
Multiple control options: Provides power regulator, pressure cut-off and other functional modules to adapt to complex hydraulic circuits.
Through-shaft drive: Supports tandem gear pumps or vane pumps to save space (such as multi-pump hydraulic stations).
Environmental adaptability
Wide temperature range operation: Stable operation within the range of -25℃~+70℃, fluororubber seals are optional for high temperature environments.
Low noise optimization: The noise is 15dB(A) lower than that of conventional pumps, improving the working environment.
II. Precautions for use
Installation and commissioning
Oil management
Cleanliness requirements: The oil must reach NAS1638 level 7 (ISO 16/13), otherwise contaminants are likely to scratch the distribution plate (accounting for 70% of failures).
Oil temperature control: Continuous operation ≤60℃, short-term peak ≤80℃, over-temperature requires replacement of fluororubber seals.
Mechanical installation
Oil drain port direction: must be installed upward, pipeline back pressure <0.2MPa, independent oil return tank.
Alignment requirements: coupling deviation ≤0.1mm, to avoid lateral force causing bearing breakage.
