PRINCIPLES OF OPERATION
The TankJet
®
65 is a hydraulically driven rotating head
that provides effective control of rotational speed to assure
optimum cleaning by the nozzle streams of internal tank
surfaces to be cleaned, sanitized, treated, or rinsed .
No reduction gears are used and therefore, minimal
maintenance is required . The nozzles are driven by a set of
bevel gears through a complete 360° path simultaneously in
both the vertical and horizontal planes . This unit is complete
with 4 nozzles which provide an indexing pattern of 2° per
revolution . The “clean line” design of this unit ensures a
minimum of outside crevices in the unit where processing
material may accumulate to cause contamination . The unit
may be installed on a permanent basis (C .I .P .) . Many types
of fluids, sanitizers, detergents, solvents and caustics may
be used through this unit to assist its cleaning effectiveness.
(Please note caution below) The cleaning effectiveness of
this unit is proportional to all the applicable variables, such
as volume, pressure, chemicals, impingement, drainage,
soils, etc . The unit will operate in any attitude so it can clean
almost any type of contained area within its range .
TECHNICAL SPECIFICATIONS
CAUTION: If chemicals, hazardous materials,
operations, and equipment are used in conjunction
with this cleaning equipment, it is the responsibility
of the user to establish appropriate associated
safety and health practices. Prior to application, the
user must consult and determine the applicability of
regulatory (federal, state, local and facility) safety and
environmental agency limitations.

CONSTRUCTION:
Referring to the Parts List on page 10, the unit consists of
two basic components; the drive assembly and the nozzle
body assembly . This unit's construction does not require
lubrication of any kind .
PRINCIPLE OF ROTATION:
The liquid enters the inlet cap (1) and then flows through
the oblique and bypass holes in the motor (3) causing a
swirling motion in the liquid . The swirling liquid goes down
the outside of the vertical shaft (5) past the 6 tooth rotor (4)
imparting rotation to the rotor and thus the vertical shaft . The
liquid then goes thru the holes in the vertical shaft and is
divided in the tee (12) to each nozzle head shaft (14) . There
are two holes in the tee allowing a constant stream of liquid
to be directed at the gear mesh to help prevent build-up .
The liquid flows into the nozzle body and out each nozzle.
The rotation of the vertical shaft causes the nozzle head
assembly to rotate in a horizontal plane . The nozzle bodies
rotate in the vertical plane by the meshing of the bevel gears
(9 & 15); bevel gear (9) has 45 teeth while bevel gear (15)
has 44 teeth. This difference in the number of teeth in each
gear indexes the nozzles with each rotation . It will take 45
revolutions for one complete cleaning cycle . Thus, if the
unit is rotating 5 RPM, it will take 9 minutes for a complete
cleaning cycle . To obtain cycle time, divide 45 by the RPM
of the head .
Normal rotation of the TankJet 65 is 5-40 RPM at 50 to 150
PSI (3 .4 to 10 .3 BAR) inlet pressure . The nozzle holes in the
nozzle body (11) are set off of true center in favor of rotation.
All units will operate in the same RPM range since a change
in nozzle size is compensated by a change in the motor
when the unit is assembled by the factory . The rotational
speed of these units can be regulated through the use
of various motor bypass plugs, which influences the fluid
diversion to provide additional speed, reference the trouble
shooting section and the drawing parts list for additional
information and location .
CLEANING DIAMETER:
The cleaning diameter is a function of rotational speed and
liquid pressure applied . The slower the head rotates and the
higher the pressure applied, the greater the distances . The
effective cleaning diameter is 40 ft. (12.2 m), but the actual
results will also depend on the type and condition of soils to
be removed .
