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.

TANKJET 65 MODEL:

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.

INSTALLATION

The TankJet® 65 is easy to install as it has a single female pipe thread connection (NPT or BSPT). It may be installed as a swing away unit or suspended from a pipe. The unit is dynamically balanced to avoid excessive sway and torque. The factory will preset the approximate speed (RPM) and nozzle size for the particular field application. In all installations a suitable strainer should be used (such as a 20 Mesh “Y” strainer) to prevent dirt or scale from clogging the waterways or openings.
WARNING:
In closed tanks, provisions should be made for adequate venting during operation to allow the escape of any gases or volatile vapors which may be produced during operation. This will also prevent the tank from collapsing due to vacuum formation, which can be caused by a cold rinse cycle in a warm tank.

OPERATION
To start the unit, turn on the fluid. An in-line valve is advised for a slow build-up of liquid pressure in the unit to prevent “water hammer”. To stop the unit, turn off the liquid. The unit should always be handled carefully. If the unit is dropped or maltreated it may cause internal damage to the drive assembly, which in turn can affect the performance of the unit. If handled properly the unit will perform well and provide dependable service.

TROUBLESHOOTING

Due to the simplicity of the unit, few problems should occur. If any trouble should arise, the following steps may be taken: Refer to the Parts List.

Check units for external damage, look for evidence of mishandling that may have damaged shafts, bearings, or alignment.
If the nozzle body fails to rotate and no liquid passes:
Check for liquid pressure and volume at the unit.
Check strainer for filter blockage.
Remove nozzles and check for obstructions.
While nozzles are off, recheck for flow through the nozzle body.
If the unit fails to rotate and sufficient liquid passes:
Check for freedom of rotation, by hand, in the suspended and inverted position, in the vertical and rotational axis.
If no visible abnormalities are discovered, the balls may have brinelled the bearing raceway surface on the nozzle body and shaft assemblies, which may have been caused by water hammer or maltreatment. If this condition is severe, the brinelled spots may be removed and a fairly smooth raceway recreated. Insert a blank motor bypass plug in the motor and slowly turn on the liquid to the highest pressure available. Operate the unit at a high rotation for about 30 minutes. Reinsert the original bypass plug and the unit should operate satisfactorily.
If the unit is free, insert a motor bypass plug. If the unit now rotates, the problem is minor friction. If the unit still does not rotate, check for:
Contamination in the unit.
Wear of the bearing parts:
The washers and the ball.
Galling and straightness of the shafts and gear

SERVICING
