PRINCIPLES OF OPERATION
TankJet ® 360 series tank cleaning machine is hydraulically driven by
the cleaning solution . As the fluid passes through the inlet, a stationary
turbine (stator) forces the liquid past the rotor which causes it to rotate
at high speed . The rotor is fastened to a rotor shaft which is supported
radially by an upper and lower bearing . The rotor shaft extends into the
gearbox, and is connected to the geartrain which reduces the speed
of the rotor shaft by either 655:1 or 273:1, depending on machine
configuration, and transmits the rotation to the Tee Housing on a
horizontal plane .
The Tee Housing has a fixed bevel gear which drives a bevel gear
mounted on the Nozzle Housing . During tee housing rotation in the
horizontal plane, the nozzle housing rotates in the vertical plane
simultaneously . Due to the difference in the number of teeth on the
bevel gears, an indexing occurs which precisely advances the nozzle
housing rotation ahead of the tee housing, creating the spherical 360
degree spray pattern for complete tank coverage .
Cycle times will vary with water pressure, flow rate and the machine
configuration . Because no two cleaning applications are the same,
TankJet 360 tank cleaning machine can be configured for specific cycle
times, nozzle dwell time and water usage . One basic machine can be
altered with interchangeable nozzles, rotors, stators and geartrain
ratios to maintain the highest degree of operating efficiency . Refer to
the performance data sheet for sample cycle times and water usage,
or call your sales representative for assistance in choosing the proper
machine configuration for your tank cleaning needs .
TankJet
®
360 series has been designed for a long reliable service
life . Every attempt has been made to design in reliability, but like
all other man-made mechanical devices, this machine is subject
to altered performance or break downs . Preventative maintenance
is the key to maintaining uninterrupted machine performance, and
minimal downtime . Due to the numerous factors that affect rotary
tank cleaners such as flow rate, pressure, chemical concentration,
etc ., it is necessary to create specific Preventative Maintenance (PM)
programs for each machine that is being used under various operating
conditions . Refer to Page 7: Preventative Maintenance or check with
your sales representative for specific recommendations .

dual-nozzle 360 6.25 in. 158 mm
triple-nozzle 360 10.25 in. 260 mm
triple-nozzle 180 12.25 in. 311 mm
INLET CONNECTION
2" NPT (F) with 2-1/2" quick disconnect (M)
2" NPT (F) with 2-1/2" NST (NH) hose thread (M)
2" BSPT (F) with 2-1/2" quick disconnect (M)
Rotor Shaft: Stainless Steel substrate is plasma flame sprayed with
Chromium Oxide, then ground to finish dimension . The final product
is a hard, dense surface that is resistant to abrasive wear, high
temperatures and chemical corrosion . The smooth surface also lends
itself to sealing with rotary seals . The thrust imparted on the rotor
shaft is distributed by a tungsten carbide thrust washer fastened to
the rotor shaft pinion gear . Carbide is an excellent wear material and
has very high corrosion resistance .
Main Bearings: The main bearings that support the rotation of the
Tee Housing and Nozzle Housing are composed of a carbon fiber
reinforced thermoplastic material, with 15% PTFE for lubricant . These
bearings have an extremely low coefficient of thermal expansion, and
both a low water absorption and wear factor . Ball bearings have been
eliminated by the use of this bearing material .
OPERATING PRESSURE AND FLOW RANGE
40 – 350 psi 2.81 – 24.61 kg /cm
30 – 300 gpm 1.89 – 18.92 ltr / sec
Temperature Range:
up to 250° F (121° C)
Seals: Static seals (o-rings) are compounded for extended use in
various tank cleaning applications . Several different types of o-rings
are available to suit specific tank cleaning environments . Dynamic
seals (which seal rotating parts) are specially designed spring or
pressure seals . The jacket material is a Teflon alloy which increases
wear life and corrosion resistance .
Geartrain:
The internal gearbox reduction is achieved using
a spur gear system, and is available in two gear ratios: 655: 1
and 273: 1 .
Geartrain Lubrication: Two types of lubrication are available;
sealed gearbox with food grade gear oil or flow-thru gearbox;
where the cleaning solution lubricates the gears . See Preventative
Maintenance, page 7 for specific types of oil .
Nozzle Housing Drive:
Pin drive or clutch drive is available . Pin
drive is recommended for CIP applications, while the clutch drive is
recommended for portable use, where the machine will be handled
often .
CIP Applications: Several self cleaning features are built into all
machines; rinsing of the bevel gears and ring gear assist in preventing
a buildup of debris that could interfere with operating efficiency . CIP
models can also be equipped with the optional self rinse nozzle which
washes the exterior surfaces of the machine while it is operating .
Additional passages allow high pressure rinsing of internal areas of
the machine where deposits of solids could allow bacterial growth .
Drainage holes can be provided for complete drainage of cleaning
solution .
Nozzle Sizes:
Nozzles are available in the following sizes:
A 1/4 in. 6.35 mm
B 9/32 in. 7.14 mm
C 5/16 in. 7.94 mm
D 3/8 in. 9.53 mm
