Changsha Blower Factory Series Products:

■ Series Introduction

AR series Roots blowers are based on the technical products introduced by our company, R series Roots blowers, and absorb It is optimized and designed using international advanced technology and is generally used to transport clean air. This model also derives a variety of sealing structure types to transport various gas media to meet different types of industrial uses.

AR series Roots blowers can be widely used in industries and departments such as petroleum, chemical industry, metallurgy, electric power, fertilizer, building materials, ore, ports, textiles, food, medicine, environmental protection, breeding and urban gas.

■ Flow range

Flow rate: 0.76～1056m3/min Pressure boost: 9.8～98kPa

■ Performance table description

Flow rate: The flow Qs in the performance table refers to the inlet flow of the Roots blower under the standard suction state (absolute pressure 101.325kPa, temperature 20°C, relative humidity 50%) and the medium is air. The flow section under non-standard conditions is converted.

Flow rate conversion: When the inlet air flow is expressed by the flow rate Qn under the reference state (temperature 0℃, absolute pressure 101.325kPa), it needs to be converted into the flow rate Qs under the standard suction state according to the following formula , and then check the performance table (humidity is usually not considered).

Qs=1.0733Qn

When the intake air temperature ts is greatly different from 20℃, or the molecular weight M of the inhaled gas significantly deviates from the air molecular weight 29, the actual intake air flow Qs presses Formula calculation:

Qb=(Qth-Qsa)×[(273+ts)/(273+20)×29/M]1/2

Qs=Qth-Qb

In the formula: Qb—the internal leakage amount m3/min when the inhaled gas temperature is ts°C and the molecular weight is M;

Qth—the theoretical flow rate m3/min; (upgrade as required Pressed inlet flow rate can be obtained from the performance table after preliminary selection according to the performance table).

Qsa—actual m3/min flow rate under standard suction state. (Flow rate shown in the performance table after preliminary selection)

Pressure unit conversion: 9.8kPa=0.1kgf/cm2=1000mmH2O=73.5mmHg=98mbar=0.0967atm

Table performance The parameters use air as the medium. If other media are transported or the air intake state does not match the standard air intake state, the flow rate needs to be converted accordingly.

■ Structural features

Forced gas transmission, the flow rate changes little with pressure, and the transported gas is not contaminated by oil.
