3. Configuration, Operation, Illustration
The cold water machines of this series mainly comprise of a low speed high
pressure inline plunger pump, which is driven by a 100 % duty electric motor
via a maintenance-free tooth belt .
The feed water is directed via a pre-filter to the high pressure pump which – in
connection with the required spray nozzle – boosts it to the stated/adjusted
working pressure. In order to protect the pump against cavitation due to poor
water flow, a low water cut-out is arranged which stops the machine as soon
as the flow pressure drops below limits.
A locked and sealed safety/control valve is installed in the high pressure
section, which opens as soon as the operating pressure is exceeded by more
than 10 % and returns the water which cannot be taken by the nozzle back
into the suction line of the pump. As a second safety device a pressure relief
valve with burst disc is installed, which is activated if working pressure is
exceeded by more than 30 %.
When closing the dump gun, then water is discharged via a by-pass through
the spray wand. When opening the dump gun again, the pressure is generated
immediately so that works can be continued without delay.
The range of applications can be extended by a variety of accessories
available from OERTZEN. Contact your local distributor.
