4 month ago
Product details
PVQ40 Variable Displacement Piston Pumpis a high-performance axial piston pump manufactured by Vickers (now part of Eaton Corporation), widely used in industrial hydraulic systems. Below is a detailed introduction to its specific features:
I. Product Features
1. Compact Structure and Smooth Operation: The PVQ40 adopts an axial design, ensuring compactness and stable output under various operating conditions, minimizing vibration and noise.
2. Low Noise Design: Through its patented internal timing mechanism, it effectively reduces pressure pulsation and noise. During actual operation, the pump's noise level is close to or lower than that of the driving motor, meeting the demands of demanding industrial environments.
3. Flexible Displacement Control: The displacement can be easily adjusted by varying the angle of the swashplate, allowing users to tailor the output according to actual needs. The pump comes with pressure compensation control (e.g., the "G" option), ensuring that the output closely matches system requirements and avoiding excessive flow losses.
4. Wide Fluid Compatibility: It supports various types of hydraulic fluids, including mineral oils, synthetic hydraulic fluids, water-containing hydraulic fluids, and lecithin-based hydraulic fluids, offering broad applicability.
5. Through-Shaft Drive Structure: It supports multi-pump combinations, allowing for the installation of various types and sizes of fixed and variable displacement pumps, forming compact and flexible assemblies that help reduce installation space and costs.
6. Durability and Long Service Life: Manufactured with high-quality materials and subjected to rigorous testing and validation, it ensures long-term stable operation, reducing maintenance and replacement costs.
II. Technical Specifications
• Geometric Displacement: 41.0 cm³/rev
• Rated Speed: 1800 rpm (maximum speed up to 3600 rpm)
• Continuous Pressure: 210 bar
• Peak Pressure: 280 bar
• Maximum Flow Rate: 73.8 L/min (at 1800 rpm)
• Noise Level: ≤64 dBA (at 1800 rpm)
• Control Methods: Supports various control methods, including pressure compensation, electro-proportional control, load-sensing control, remote pressure regulation, and constant pressure control.
III. Application Fields
Due to its high performance and wide adaptability, the PVQ40 Variable Displacement Piston Pump is widely used in the following fields:
1. Oil and Gas Industry: Used in drilling, oil extraction, and oil and gas transportation processes. Its high efficiency and long service life make it ideal for high-pressure, high-flow, and high-reliability environments.
2. Manufacturing Industry: Used in hydraulic systems of various machine tools, production lines, and assembly lines, providing stable and efficient fluid power.
3. Construction Industry: Used in concrete pumping, material lifting, and hydraulic jacks, among other applications. Its robust and durable characteristics enable reliable operation in harsh construction environments.
4. Agriculture and Forestry: Used in hydraulic systems of tractors, harvesters, irrigation equipment, and forestry machinery, providing powerful driving force.
5. Marine and Offshore Engineering: Used in hydraulic systems of ship propulsion, steering gear, windlasses, and underwater equipment, among others. Its reliability and durability make it an ideal choice for marine environments.
IV. Model Selection and Options
The PVQ series of variable displacement piston pumps come in various sizes (e.g., PVQ5, PVQ10, PVQ13, PVQ20, PVQ25, PVQ32, PVQ40, PVQ45), allowing users to select the appropriate model based on actual needs. When selecting a model, consider the following factors:
• Displacement Requirements: Choose the appropriate displacement based on the system's flow requirements.
• Pressure Requirements: Select the appropriate continuous and peak pressures based on the system's operating pressure.
• Control Methods: Choose the appropriate control method (e.g., pressure compensation, electro-proportional control) based on the system's control needs.
• Mounting Interface: Select the appropriate mounting form based on the equipment's installation space and interface type.
