Understanding the Parker PV Series Pumps
When it comes to hydraulic pumps, the Parker PV series stands out as a reliable and efficient choice. Designed for a wide range of applications, these pumps are known for their robust construction and advanced features. In this article, we will delve into the details of the Parker PV series pumps, focusing on their specifications, features, and applications.
Series Overview
The Parker PV series includes various models, each with its unique specifications and capabilities. These models range from PV016 to PV270, offering a maximum displacement of up to 270ml/rev. The rated working pressure of these pumps is 350bar, and they operate at a minimum speed of 300 rpm. One notable feature of these pumps is that the oil outlet is positioned upwards, which ensures efficient oil flow and reduces the risk of leakage.
Model Variations
The Parker PV series pumps come in different models, each designed to cater to specific requirements. Some of the popular models include PV016, PV020, PV023, PV032, PV040, PV046, PV063, PV080, PV092, PV140, PV180, and PV270. These models are designed to meet the needs of various applications, from industrial machinery to mobile equipment.
Technical Features
The Parker PV series pumps are equipped with several advanced features that make them a preferred choice among users. Here are some of the key technical features:
-
Standard and Power Regulators: These pumps come with both standard pressure regulators and power regulators, allowing for precise control of the hydraulic system.
-
Fast Response: The variable control pistons are equipped with strong澶嶄綅 springs, ensuring a quick response time. For instance, the PV046 model has a response time of less than 70ms when moving from zero to maximum displacement and less than 40ms when moving from maximum to zero displacement.
-
Compensation System: The pumps are equipped with an active pressure relief system, which reduces the pressure peak at zero flow variable, ensuring smooth operation.
-
Stable Compensation at Low Pressure: These pumps offer stable compensation regulation at low working pressures, with a minimum compensation pressure of 12-15bar.
-
Low Flow Pulsation: The 9-piston design and the use of pre-compression volume technology minimize flow pulsation, resulting in a smoother operation.
-
Optimized Structure: The pump body is designed with FEM optimization, which reduces noise levels and ensures a quieter operation.
Hydraulic Fluid Recommendations
To ensure optimal performance and longevity of the Parker PV series pumps, it is recommended to use mineral oil-based hydraulic fluids. These fluids should comply with the DIN 51524 Part 2 standard and have a Brugger value greater than 30N/mm2 for general applications. For heavy-duty hydraulic equipment and systems with rapid cycling and/or heavy dynamic loads, a Brugger value greater than 50N/mm2 is recommended. The Brugger value should be measured in accordance with the DIN 51347-2 standard.
Viscosity Range
During normal operation, the oil viscosity should be within the range of 16-46 mm虏/s to ensure smooth and efficient operation of the Parker PV series pumps.
Applications
The Parker PV series pumps are widely used in various industries and applications, including:
-
Mobile Equipment: These pumps are commonly used in construction, agriculture, and mining equipment.
-
Industrial Machinery: They are suitable for use in machine tools, conveyors, and other industrial applications.
-
Aerospace: The advanced features and reliable performance of these pumps make them ideal for use in aerospace and aviation applications.
Conclusion
The Parker PV series pumps are a versatile and efficient choice for a wide range of hydraulic applications. With their advanced features, robust construction, and wide range of models, these pumps are sure to meet your specific requirements. Whether you are looking for a pump for mobile equipment, industrial machinery, or aerospace applications, the Parker PV series is a reliable choice.
