PRINCIPLES OF OPERATION

NOTE: The unit will only operate properly when mounted in the vertical position (suspended or inverted).

The TankJet® 80 models are hydraulically driven rotating heads 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 will provide a complete 360° indexing path in both vertical and horizontal planes, with the index pattern repeating every 45 revolutions. The “clean line” design of the TJ80H unit ensures a minimum of outside crevices in the unit where processing material may accumulate to cause contamination. It may be installed on a permanent basis (C.I.P.) and can clean almost any type of contained area within its range. Many types of fluids, sanitizers, detergents, solvents and caustics may be used through the TankJet 80 to assist in its cleaning effectiveness.

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.

MATERIALS:
316 Stainless Steel (UNS S31600), PTFE and UHMW-PE

CONSTRUCTION:
Referring to the Parts List, the unit consists of two basic components; the drive, comprising of the body, motor, rotor, and shaft; and the nozzle head, comprising of the nozzle body, bushings, nozzles, and elbow shaft.

PRINCIPLE OF ROTATION:

The liquid enters the inlet cap (1) and then flows through the oblique and bypass holes of the inlet disc (6) causing a swirling motion in the liquid. The swirling liquid goes down the outside of the vertical shaft (2) imparting rotation to the 4 tooth impeller (9) and thus the vertical shaft. The liquid then goes thru the holes in the vertical shaft and thru the elbow to the horizontal shaft (15). There is a hole in the elbow 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 water leakage from the bottom of the unit is necessary to lubricate the vertical radial bearings and to flush out particles which may cause the unit to jam. The nozzle bodies rotate in the vertical plane by the meshing of the bevel gears (12 & 16); bevel gear (12) has 45 teeth while bevel gear (16) has 44 teeth. This difference in the number of teeth in each gear indexes the nozzles with each rotation.

CLEANING DIAMETER:

The cleaning distance is a function of rotational speed and liquid pressure applied. The effective cleaning diameter is 50 ft. (15.3 m). The nozzle extensions (22) concentrates the stream for greater reach. If striping occurs on tank walls then the extensions may be removed. This will provide a thicker stream, but will sacrifice about a 10 ft. (3 m) diameter of throw.

Caution Pinch Point: Bevel gears on the nozzle hub and body can pinch skin and/or fingers. When handling the TankJet 80 be sure to hold it from the nozzles and not the body

INSTALLATION

The TankJet 80 or TankJet 80H is easy to install as it has a single 1-1/2″ female pipe thread connection (NPT or BSPT). It may be installed on a tripod, suspended from a pipe, manhole cover, etc., but the unit must be VERTICAL. 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.

OPERATION

To start the unit, turn on the fluid. An in-line valve is required 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 with caution. Make sure nozzles are screwed on the body and hold TankJet 80 by its nozzle not the body. The nozzle hub will rotate freely and bevel gears can pinch skin and/or fingers. 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.

TROUBLE SHOOTING

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

A. Check units for external damage, look for evidence of mishandling that may have damaged shafts, bearings, or alignment.
B. If the nozzle body fails to rotate and no liquid passes:

1. Check for liquid pressure and volume at the unit.
2. Check strainer for filter blockage.
3. Remove unit and check for clogged jet holes.
4. With the nozzle removed, recheck for flow through the unit.
5. Remove the inlet cap and check the holes of the inlet disc. Check to see that no foreign material is
   preventing the unit from rotating.

C. If the unit fails to rotate and sufficient liquid passes:

1. Check for freedom of rotation, by hand, in the vertical and rotational axis.

2. If no visible abnormalities are discovered, the unit may have been dropped and internal damage is suspect.

3. If the unit still does not rotate, check for:

   • Contamination in the unit.

   • Wear of any one of the following parts:
     The bushings, washers, and the rotor.

   • Galling and straightness of the shafts and gear
