20v5a1c22r, 20v5a1b22r vane pump model description and technical parameters

Guangdong Heli Hydraulic is a well-known brand in the field of hydraulics. The vane pumps it produces are known for their high performance and durability. Among the many models, 20V5A1C22R and 20V5A1B22R are two very representative products. This article will introduce the model description and technical parameters of these two hydraulic vane pumps in detail to help users better understand and choose.

1. Model Description

20V5A1C22R: This vane pump is one of the V series low-noise fixed displacement vane pumps, designed for industrial applications. Among them, "20V" represents the series or basic model of the pump, "5A" represents a certain displacement or specification of the pump, "1" is the shaft extension of this hydraulic pump, "C" represents the oil outlet position of this oil pump, "22" is the design code of this hydraulic pump, and "R" is the rotation direction of the vane oil pump. The entire model reflects the basic characteristics and functions of the pump.

20V5A1B22R: Similar to 20V5A1C22R, this vane pump also belongs to the V series, but 1B22R means that the oil outlet position is different from the former.

2. Technical Parameters

①Basic parameters

Displacement: The specific displacement of these two pumps may vary depending on the model suffix (such as 5A), but both belong to the small and medium displacement range and are suitable for a variety of industrial scenarios.

Pressure: The maximum working pressure of these two vane pumps can reach 138bar to 207bar, which can meet the pressure requirements of most industrial hydraulic systems.

Speed: The speed range of the two hydraulic oil pumps is wide, ranging from a minimum of 600r/min to a maximum of 1800r/min, and can be adjusted according to actual working conditions.

② Structural design

Parent-child blade structure: These two pumps adopt a parent-child blade design, which effectively reduces the impact of the blades on the stator and improves the stability and life under high working pressure and high speed.

Low noise characteristics: The parent-child blade structure itself has the characteristics of low noise, and the design of 12 blades makes the flow pulsation very small and the noise is lower.

Multiple displacement options: Yihe V series vane pumps provide a variety of displacement options, as well as a plug-in structure for the pump core, allowing users to flexibly configure according to actual needs, while also making maintenance more convenient.

③ Driving data

Direction of rotation: The pump is assembled to rotate clockwise or counterclockwise, the direction of rotation is viewed from the shaft end. The oil inlet and outlet remain unchanged, regardless of the direction of shaft rotation. If the direction of shaft rotation needs to be changed, the assembly of the internal parts must be changed.

④ Other parameters

Weight: Both pumps weigh approximately 12kg, making them easy to install and carry.

Shell material: Made of cast iron, with good durability and corrosion resistance.

Installation stop: The size of the installation stop is 32mm, which is convenient for users to install and fix.

3. Conclusion

The 20V5A1C22R and 20V5A1B22R vane pumps are widely recognized by the market for their high performance, low noise and flexible configuration. Whether in industrial production lines, mechanical equipment or other hydraulic systems, these two oil pumps can play an excellent role. When choosing, users can make comprehensive considerations based on actual working conditions and needs, combined with the above technical parameters, to choose the most suitable product for themselves.
