How to Read Flow Characteristics Graph
Flow characteristics are expressed in ejector
vacuum pressure and suction flow. If suction
flow rate changes, a change in vacuum
pressure will also be expressed. Normally this
relationship is expressed in ejector standard
use.
In graph, Pmax is max. vacuum pressure and
Qmax is max. suction flow. The valves are
specified according to catalog use.
Changes in vacuum pressure are expressed
in the order below.
1. When ejector suction port is covered and
made airtight, suction flow becomes 0 and
vacuum pressure is at maximum value
(Pmax).
2. When suction port is opened gradually, air
can flow through, (air leakage), suction flow
increases, but vacuum pressure decreases.
(condition P1 and Q1)
3. When suction port is opened further,
suction flow moves to maximum value
(Qmax), but vacuum pressure is near 0.
(atmospheric pressure).
When vacuum port (vacuum piping) has no
leakage, vacuum pressure becomes
maximum, and vacuum pressure decreases
as leakage increases. When leakage value
is the same as max. suction flow, vacuum
pressure is near 0.
When ventirative or leaky work must be
adsorbed, please note that vacuum
pressure will not be high.
