2.MACHINE DESCRIPTION
FKC 65 UB is a Scrubber-Dryer machine, driven by an operator seated on board, to
wash and dry hard floors, battery powered, intended for commercial use.
The main systems of the machine are as follows:
▪The detergent solution tank and relevant circuit,
▪The washing brushes plate
▪The dirty water recovery tank and relevant circuit
▪The electrical system and relevant control panel, the steering and speed device.
The function of the detergent solution tank is to store water (with dilution of any
detergent), supplying it to the washing system.
The relevant system includes the tank, filter, proportional valve to adjust flow rate and
controls.
The tank contains the detergent solution (water and detergent) and supplies it to the
washing system when required. The filter protects the solenoid valve from debris
contained into the water. The proportional solenoid valve controls detergent solution
supply to the washing system. The valve automatically prevents the flow of the detergent
solution. The control selector of the solution flow - by controlling opening duration and
section of the solenoid valve - regulates the amount of detergent solution conveyed to
the washing system.
The disc washing device includes: two counter-rotating disc brushes, the electric motor,
the actuator to lift the entire brush unit, the manual cam for lifting the wiper only and the
controls. The brushes wash the floor while the motor and the pair ofgears, solidly attached
to the brushes, actuate their motion. The side band, in bristles, lets the detergent solution
remain in the brushes' working area.
The wiper (or squeegee) is the water collecting device.
The water flow is regulated by a proportional solenoid valve (from 0 to 3.5 litres/minute),
there is also the option of mixing the water with the chemical detergent, contained in the
relevant bottle. The mixture percentage is set by a peristaltic pump which regulates the
detergent flow, conveying it and mixing it downstream of the proportional solenoid valve
(in the version with Ki-Do device).
The function of the recovery device (wiper or squeegee) is to suck the dirty water and
convey it to the recovery tank.
The recovery system includes: the wiper, the vacuum turbine, the filter, the recovery tank
and the controls. The wiper collects the dirty detergent solution from the floor as the
machine moves forward. The vacuum turbine assures the necessary vacuum to suck the
dirty detergent solution from the floor and convey it to the recovery tank. The filter
protects the turbine against the debris and foam. The recovery tank stores the dirty
detergent solution.
