    Performance parameters of air suspension centrifugal blower

    Date:2016-07-27      Click:

    Flow rate, pressure ratio, shaft power, rotating speed and efficiency are the main performance parameters of air suspension centrifugal blower, also known as the performance parameters of centrifugal blower.

    flow

    The volume or mass of gas flowing through the ventilator in unit time is called flow Volume flow: the volume of gas flowing through the blower per unit time. The common units are m3 / s, m3 / min and m3 / h. Mass flow: the mass of gas flowing through the blower in unit time. The unit is kg / s, kg / min and kg / h.

    Pressure ratio

    The pressure ratio of blower refers to the ratio of inlet absolute pressure and exhaust absolute pressure.

    speed

    It refers to the rotating speed of the blower rotor, which will directly affect the flow, pressure and efficiency of the blower. The unit is R / min, usually n.

    Shaft power

    The power n required to drive the blower is called shaft power, or the energy transmitted to the blower shaft in unit time, unit: kW.

    Stage efficiency

    A blower is a machine used to increase pressure. The stage efficiency of centrifugal blower is mainly used to explain the utilization degree of mechanical energy transmitted to gas. In centrifugal blower, variable efficiency and constant entropy efficiency are often used. Variable efficiency refers to the ratio of the variable compression work required to increase the intake pressure 1p to the exhaust pressure 2p to the actual work consumed (i.e. total work consumed totw). The constant entropy efficiency refers to the ratio of the work of constant entropy compression to the work actually consumed when the intake pressure 1p is increased to the exhaust pressure 2p.
