Checking the injector performance
Good injector performance is necessary for proper gas feeder
operation. The gas feeder is tested to ensure that it will deliver the
required amount of gas when used at the correct hydraulic condi-
tions. If the injector performance is poor check the following:
•
Dirty Water Strainer
A strainer is required in the water line prior to the injector to
prevent foreign matter from blocking the injector throat ports. If
sufficient material is allowed to build up on the strainer sur-
face, the resultant pressure drop across the strainer reduces
the injector operating water pressure. If the pressure drop is
excessive, the injector will not be able to pull the required gas
flow. Regular periodic inspection and cleaning of the strainer
will minimise the possibility.
•
Installation of Throat and Tailway
The throat and tailway must be assembled as shown on the
parts drawing. If faulty injector action is suspected, inspect the
gaskets and replace them if necessary.
•
Blocking of the Injector Ports
The injector will not operate satisfactorily unless all its ports
are clear. The quality of the injector water supply is easily che-
cked by visual inspection after the throat has been removed. If
the water supply contains appreciable quantities of manga-
nese or iron, these may deposit in the throat or tailway over a
long period and eventually interfere with the injector action.
Such deposits are readily recognisable by their black or red-
dish colour. They may be removed by immersing the throat in
a dilute (10%) solution of hydrochloric acid (known commer-
cially as muriatic acid).

Yearly Maintenance
1
Strip down the gas feed system, clean all pipe-lines and the
components in accordance with the Section 6.1.
2
Replace the parts according to the maintenance parts kit
„Yearly“
3
On completion of the overhaul, carry out the Preparation for
Initial Operation at Section 4.11.
4
Thoroughly check and inspect all solution delivery pipework.
5
Replace the filling of the activated carbon filter.
