■ Series introduction

AR series roots blower is optimized by absorbing international advanced technology on the basis of R series roots blower imported by our company, and is generally used for conveying clean air. This model also comes from various sealing structures, which are used to transport different gas media to meet different kinds of industrial purposes.

AR series Roots blowers can be widely used in petroleum, chemical industry, metallurgy, electric power, fertilizer, building materials, ore, port, textile, food, medicine, environmental protection, aquaculture, city gas and other industries and departments.

■ Flow range

Flow rate: 0.76 ~1056m3/min; Booster: 9.8 ~ 98 kPa.

■ Performance table description

Flow rate: The flow rate Qs in the performance table refers to the inlet flow rate of Roots blower in standard suction state (absolute pressure1kloc-0/.325 kPa, temperature 20℃, relative humidity 50%), and the flow rate in non-standard state is converted.

Flow conversion: when the intake flow is expressed by the flow Qn in the reference state (temperature 0℃, absolute pressure110 1.325kPa), it should be converted into the flow Qs in the standard intake 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 obviously different from 20℃, or the molecular weight m of the inhaled gas is obviously different from the molecular weight 29 of the air, the actual intake air flow Qs is calculated according to the following formula:

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

Qs=Qth-Qb

Where: QB is internal leakage, m3/min；; When the suction temperature is ts℃ and the molecular weight is m;

Qth-theoretical flow m3/min；; ; (According to the intake air flow under the required pressurization, look it up from the performance table after preliminary selection according to the performance table).

Qsa——Actual m3/min flow under standard inhalation conditions. (Process shown in the performance table after preliminary selection)

Pressure unit conversion: 9.8kpa = 0.1kgf/cm2 =1000mmh2o = 73.5mmhg = 98mbar = 0.0967atm.

The listed performance parameters take air as the medium. If other media are transported or the air intake state is inconsistent with the standard air intake state, the flow rate needs to be converted accordingly.
