■ Series Introduction
AR series Roots blower is optimized and designed by absorbing the international advanced technology on the basis of R series Roots blower, which is introduced by our company, and it is generally used for conveying clean air. This model is also derived from a variety of sealing structure type, used to transport a variety of different gas media, to meet different kinds of industrial use.
AR series Roots blower can be widely used in petroleum, chemical, metallurgy, electric power, chemical fertilizer, building materials, ore, ports, textile, food, medicine, environmental protection, breeding and city gas and other industries and departments.
■ Flow rate range
Flow rate: 0.76-1056m3/min Boost pressure: 9.8-98kPa
■ Performance table description
Flow rate: flow rate Qs in the performance table refers to the standard suction state (absolute pressure of 101.325kPa, temperature of 20 ℃, relative humidity 50%), the media for the air inlet flow rate of the Roots Blower. The inlet flow rate, for the non-standard state of the flow section for conversion.
Flow conversion: when the inlet flow with the base state (temperature 0 ℃, absolute pressure 101.325kPa) under the flow rate of Qn, need to be converted to the standard suction state of the flow rate of Qs according to the following formula, and then check the performance table (usually do not take into account the humidity).
Qs=1.0733Qn
When the intake air temperature ts and 20 ℃ difference is large, or the molecular weight of the inhalation gas M significantly deviates from the molecular weight of the air, 29, the actual intake air flow rate Qs is calculated according to the following formula:
Qb = (Qth - Qsa) × [(273 + ts) / (273 + 20) × 29 / M]1/2
Qs=Qth-Qb
In the formula: Qb-internal leakage m3/min when the temperature of the inhaled gas is ts ℃ and the molecular weight is M;
Qth-theoretical flow rate m3/min; (according to the inlet flow rate under the required pressure rise, which is found from the performance table after preliminary selection according to the performance table) .
Qsa-actual m3/min flow rate under standard suction condition. (Preliminary selection after the performance table shown in the flow)
Pressure unit conversion: 9.8kPa = 0.1kgf/cm2 = 1000mmH2O = 73.5mmHg = 98mbar = 0.0967atm
The table lists the performance parameters of the air as a medium, such as the delivery of other media or air intake state does not match the standard intake state, the flow rate should be converted accordingly. The flow rate should be converted accordingly.
