What are the specifications of vickers vane pump
Vickers vane pumps offer a wide variety of specifications, including both fixed-displacement and variable-displacement pumps. The displacement ranges vary significantly across series, meeting diverse operating requirements from low-pressure, low-flow applications to medium-pressure, high-flow applications. Specific specifications are as follows:
1. Fixed-displacement vane pumps (represented by the V series)
Frequent-displacement vane pumps are designed specifically for medium-pressure industrial applications. They utilize a pressure-balanced modular structure, offer a wide range of displacements, and are available in a variety of flow specifications. Common single-pump models and parameters are as follows:
Model Series: 20V, 25V, 35V, 45V
Displacement Range: 5.2-193 cm³/rev (some materials indicate 7-193 cc/rev), 16 flow specifications available
Supporting Specifications:
Working Pressure: 200-350 bar
Speed: 2400-3600 rpm
Volume Efficiency: Over 90%
Noise: As low as 62 dB(A)
Reliability: High
II. Variable Vane Pumps (represented by the VVS and VVP series)
Variable vane pumps adjust displacement according to system requirements and are suitable for applications requiring flexible flow control. Model series and parameters are as follows:
Model series: VVS (low pressure), VVP (high pressure)
Displacement range: 6-100 cm³/r, divided into four sizes:
Size 0: 6, 10, 12 cm³/r
Size 1: 16, 20, 25 cm³/r
Size 2: 32, 40, 50 cm³/r
Supporting performance:
VVS maximum pressure: 100 bar
VVP maximum pressure: 160 bar
Control method: Supports dual pressure control (select models)
Adjustment method: Displacement can be adjusted via hydraulic or mechanical regulators
III. Duplex and Multi-Vane Pumps
Double and multi-vane pumps utilize a concentric rotor structure, achieving multiple suction and discharge cycles and featuring radial hydraulic balancing. They are suitable for applications requiring simultaneous actuation of multiple actuators. Common models are as follows:
Twin pump models: 2520V, 3520V, 3525V, 4520V, 4525V, 4535V
Displacement combinations: Displacement ranges from 20 cm³/r to 373 cm³/r, depending on the model and structure.
Features: Low flow pulsation, low noise, and high durability, capable of over 10 million pressure cycles at rated continuous pressure.
