2.3 Function
The Functional Diagram (refer chapter 3 of this Manual) shows the machine‘s mode of action .
The Wap machine is divided into two (2) structural main groups, as follows:
structural main group I = drive motor with piston pump, regulation safety block with low water cut-off (flow
control)
structural main group II = heat exchanger with oil burner and temperature control
Functional Cycle:
The water feed is controlled via a foat valve. The Wap high pressure pump takes the water in, from the water tank,
pumping it, under pressure and through the heating coil, to the high pressure nozzle.
For sake of pressure control and pressure limitation, a regulation safety block is installed before the heating coil. Via
a dosing valve with automatic rinse , it is possible to add to the high pressure jet the desired cleaning and care agents.
Upon request, hot water can be produced by means of the fuel-oilheated heat exchanger. Water temperature is
controlled via a thermostat.
The fuel oil burner is fed with fuel oil via a fuel oil pump wich is flanged onto the oil burner motor. Fuel is injected,
under pressure, into the combustion chamber. A high pressure blower admits air for combustion. The igntion
transformer produces high voltage sparks at the ignition electrodes, which again provide for igniting the fuel.
Should the conveying capacity drop beneath a certain fixed value, then the burner is fully automatic disconnected.
Thus, the machine will never be overheated. As additional safety element, a thermal cutout is installed at the heat
exchanger‘s entry side.
When closing the trigger gun on/off, the fuel oil burner is switched off via the regulation safety block.
When actuating the trigger gun on/off, pressure drops, the regulation safety block again turns on the fuel oil burner.
Water quantity, pressure and temperature are infinitely variable.
