Industrial Roots Positive Displacement Blower PD For Chemical Powder Handling Plant

Full Assembly industrial Roots Blower for Chemical Powder Handling Plant

Product Introduction

The performance tables give model number,bore, r.p.m, discharge pressure, air capacity and required power of the blower.

The air capacity in the tables is indicated in the standard suction state.The standard suction state herein mentioned is defined as the condition at 20℃ temperature, 1.0332Kgf/cm² (101.3KPa) absolute pressure and 65% relative humidity.

The reference air capacity (temperature 0℃ and 1.0332kgf/cm² (101.3kpa) absolute pressure) is generally indicated in Nm³/min.

However, it may be converted into the standard air capacity by the following equation, if the suction pressure is equal.

Qs = QNx1.0732

Where, Qs: standard air capacity (m³/min); and

QN: reference air capacity (m³/min).

The discharge air capacity can be converted into the standard air capacity by the following equation.

Qs = Qdx (1.0332+Pd)/ 1.0332x(273+Ts)/(273 + Td)

Where, Qd : discharge air capacity, in m³/min;

Pd : discharge pressure, in Kgf/cm²,

Ts : suction temperature, in ℃,

Td : discharge temperature, in ℃.

According to the air capacity and discharge pres.sure as calculated above,the model, bore, r.p.m. and required power can be found in the performance table.
