Liquid
Jet Exhausters
E700 Series |
|
The liquid jet exhauster
is used to suck, entrain and pump out gases from its source point utilizing
a high pressure motive liquid such as water or other liquid. Motive liquid
is discharged at a high velocity through a specialized nozzle and sprayed
through body and venturi throat & tail.
Specially designed nozzle
creates a full cone spray. The liquid spray covers and seals the exhauster
throat and fills the tail portion of the exhauster to create effective self
priming action. The nozzle converts the pressure energy of the motive
liquid into a high velocity spray. When the sucked gas is mixed with
the high velocity motive liquid, momentum of the motive liquid is
transferred to the suction gas. This transfer in momentum creates vacuum.
The liquid & gas stream
enters the exhauster throat and passes through tail where the velocity
energy is converted into an intermediate discharge pressure. Lower the
temperature or lower the vapour pressure of motive liquid a higher vacuum
level can be obtained.

MATERIAL OF CONSTRUCTION |
|
Various metals & plastics
can be employed for exhauster body & nozzle depending on service
conditions, fluid and its properties. Typically exhausters can be
supplied in cast-iron, carbon steel, stainless steel, titanium, Hastalloy, Monel
metals. In plastics PVC, CPVC, Teflon and Polypropylene can
be supplied.
