Current capacity
(1) mass flow: Qm, the unit time flows-in after
the ventilator gas quality, the unit: Kg/s.
(2) volumetric flow: The qvsg1, unit time flows-in after
the air blower suction flange place gas volume. The commonly
used unit includes: M3/s, m3/min, m3/h.
Pressure
The air blower pressure refers to the gas in ventilator
pressure lifting value, or said is difference of the air blower import
and export place gas pressure. The unit is Pa, other units
include: MmH2O, mBar, mmHg and so on. It has moves the
pressure, the static pressure, the entire pressure division of.
(1) air blower pressure: Difference of the air blower
exportation stagnation pressure gentle breeze machine import
stagnation pressure, also is the unit volume gas the total energy
which later will obtain through the air blower
(3). air blower static pressure: The air blower
pressure subtracts with a Mach coefficient revises ventilates the
mobile pressure.
Power
(1). air blower unit quality merit: Through air
blower unit quality fluid energy increase.
(2). air blower unit quality static merit
(3). air blower air power: Mass flow and air
blower unit quality merit product, or import volumetric flow,
compression correction coefficient kP gentle breeze machine pressure
product.
(4). air blower static air power: Mass flow and air blower
unit quality static merit product, or import volumetric flow,
compression correction coefficient kPs gentle breeze machine static
pressure product
(5). impeller power: Supplies air blower impeller
mechanical efficiency.
(6). air blower shaft power: Supplies wind engine shaft
mechanical efficiency.
(7). electrical machinery output: Electrical machinery or
other 原动 machine output shaft power.
(8). electrical machinery power input: Motor-driven
equipment 端子 on supplies electric power.
¨ efficiency (1). air blower impeller efficiency: The air
blower air power with eliminates by the impeller power. (2). air blower impeller static efficiency: The air
blower static air power with eliminates by the impeller power. (3). air blower 轴效? The air blower air power
with eliminates by the air blower shaft power. (4). air blower electrical efficiency: The air
blower air power with eliminates by the electrical machinery output. (5). overall effectiveness index: The air blower air
power with eliminates by the electrical machinery power input.
