1. At start up the water passes through
the easy start valve
until the speed of
the water moves the ball against its
seat. Thus pressure can start building
up.
2. With open gun the pump is running at
working pressure. The hp-water passing
through the non-return valve.The control
piston is in balance, the spring keeps
the end-switch active.
Schematic function 1~ and 3 ~
The difference betweeen the 1 ~ and the 3 ~ function is the easy start valve in the single phase valve
block.
In the majority of the single phase versions the easy start valve will be enabled.
With disabled easy start valve the function will be as the three phase version.
In the following figures (1 - 5) the schematic funtion is shown.
7.1 Precondition: Water circulating through the valve block. Power has just been switched
ON.
7.2 Precondition: Power ON - Open gun.
7.3 Precondition: Gun is just about being closed.
7.4 Precondition: Power ON - Closed gun = Standby mode.
7.5 Precondition: Power ON - Open gun - FlexoPower turned to low pressure - Open
detergent valve.
In the three phase version, fig.D.7.1 just has to be skipped.
Colour code : Light blue - Vacuum
Blue - Supply pressure
Purple - Reduced pressure
Red - High pessure
