Principles of Operation Model 360 and 363

The Model 360 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 chromium oxide coated rotor shaft which is supported radially by and upper and lower tungsten carbide 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 61 tooth bevel gear which drives a 60 tooth 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, GPM and the machine configuration. Because no two cleaning applications are the same, the Model 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 gear train 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 you tank cleaning needs.

The Model 360 tank cleaning machine 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 GPM, 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 Section 2: Preventative Maintenance or check with your distributor for specific recommendations.
