3. General Description
The Scanjet SC 45TW is media driven and
lubricated tank cleaning machine. No lubrication
substances as oil grease etc. are used.
Functional Principle
When cleaning media enters the machine it
passes through a turbine and a worm gearbox.
Then the media enters a nozzle housing leading
it out through the nozzles. The turbines rotation
drives the worm gearbox making the machine
rotate around its own body on the same time as
the nozzle housing is forced to rotate.
A combined motion of the machine body and
the nozzle housing creates a criss-cross cleaning
pattern inside the tank. After 11 1/4 rotation of
the machine, a first course pattern has been created inside the tank as shown on
fig 1. This process is repeated 4 times, each time indexed from each other until
a full cleaning pattern will be created inside on the tank walls as per fig 2. When
this is finalized, after 47 rotations of the machine or 49 rotations of the nozzle
housing, the first cycle will be repeated.
Cleaning of tanks is a process depending on a number of factors such as soilage of
the tank, distance between nozzles and tank walls, cleaning procedure, cleaning
agent, temperature and more. All of these factors need to be considered to
accomplish a proper cleaning.
The rotation speed of the machine is depending on flow rate through the
machine. Higher flow rate makes the turbine spin faster and because of this
the machine is equipped with different turbines according to nozzle size and
intended operating parameters.
