3. General Description
Cleaning media comes from the supply line and enter through the inlet housing,
passing over a turbine which drives the drive unit via a magnetic coupling,
continue through the main pipe to the nozzle and then out in the tank.
The drive unit will rotate a shaft inside the machine, the
turning shaft. The turning shaft is connected to the bottom
housing that rotates the nozzles via a gear system. The
nozzles will hereby clean the tank in a criss-cross pattern.
The rotation speed is controlled by the rotation speed of
the turbine and could easily be set to desired speed, see
“7.7. Speed Adjustment” on page 20.
The rotations of the nozzles are indicated on the top nut
visible through the cofferdam or on the top shaft on top
of the drive unit.
The rotating nozzles will create a cleaning pattern as per
below on the vertical tank-walls. After one cycle a cleaning
pattern will be created as per fig 1. After four cycles the
pattern will be completed as per fig 2. After this the
pattern will be repeated.
A full pattern is created when the main body has rotated 47 turns. With a
rotation speed of 2 rpm will a full pattern take approx. 23,5 min. Note that the
time is depending on the actual setting of the turbine and water pressure. One
cycle will take about 6 minutes.
Cleaning of tanks is a process depending on a number of factors; the soilage of
the tank, distance to tank walls, cleaning procedure and cleaning agent. All these
factors are deciding for the number of cycles that needs to be run.
