Ratio Adjustment
Understanding the terms used with the
Hydra–Cat (H.P.)
System
, how it functions, and how to find and set the
correct
ratios
for your application is the key to easier, more
versatile operation of your proportional system.
Be sure to read and understand the following information
before operating the equipment.
Terms
Ratio
refers to the simultaneous output of a certain volume
of fluid by the
primary
and
secondary pumps.
The
primary pump (A)
is directly under the
air motor (H)
;
it usually pumps the
base
fluid. The
secondary pump (B)
is on the opposite end of the
lever arm (E);
it usually
pumps the
catalyst
. The ratio of the secondary pump(s)
can be changed by adjusting the
ratio adjustment screw
(C).
See Fig. 4.
There are three main steps when applying the use of ratios:
(1) determine the ratio that is required, (2) calculate the
ratio setting, and (3) set the ratio on the Hydra-Cat H.P.
system.
