3.3 Theory of Operation
The B&C SI models use a single-speed motor to drive the cylinder via V-belts in all speeds. The
cylinder is supported by two spherical roller bearings located in split pillow block housings made
of cast steel.
The motor is controlled by the computer control located in the front and the AC inverter drive
located in the rear panel. Any speed can be programmed for any wash cycle. Some speed ranges
are blocked out for programming due to safety reasons. These speed ranges are ones that the
machine cannot operate at due to its spring or suspension resonance. This speed range is not
important and normal speeds for wash or extraction are not within this range. Any wash speed
in the range of 10-50 RPM and extraction speeds 150 to max RPM can be programmed. Further,
any reversing action can be programmed. Normal reversing action is 16 seconds forward, pause
for 4 seconds, and 16 seconds reverse. Any temperature between 70F to 200F (20-95C) can be
programmed. Any water level in the range of the machine parameters can be programmed in
centimeters. The computers will automatically provide safety levels for steam injections and door
operations.
Water entry into the machine is through electromagnetic water valves controlled by the computer.
The computer also controls the drain, supply dispenser, any external liquid supplies, steam injec-
tion and any other vital functions of the wash program. The control also records cycles and data
of importance that are used for maintenance purposes.
The steam, if installed is injected in the bottom of the shell via a steam injector. The steam is
controlled by a steam valve that is activated by the control.
The cylinder is perforated, allowing water to pass through and drain from within during drain
and extract steps. Lifting ribs inside the cylinder lift the load from the wash solution and allow
the load to tumble and falling back into the solution when the load reaches the approximate 10-11
oclock or 1-2 oclock positions. This mechanical action removes soil from the fabric. Furthermore,
