2.1 Theory of Operation
The Rotorspray 97115 is clamped in a fixture. The dispensing valve is clamped in the
holder of the rotorspray so that the tip of the flexible dispensing needle is directed to the
inside of the wetting holes on the rotor disk.
The LOCTITE
®
Controller 97153/97204 or the Controller 97152 must control:
– Switching on of the rotorspray.
– The preselected dispensing time after the rated rotor speed is reached.
– Switching off of the rotorspray.
As long as the dispensing valve is open, the product is dispensed through the wetting
holes by centrifugal force and uniformly distributed onto the cylindrical inner surface of
the part.
In conjunction with an advancing slide, reaching the end of the advancing movement
triggers the dispensing.
The head of the rotorspray has a longitudinal play of 5 mm. Within this distance,
unintentional contact with an obstacle can be compensated without the rotor disk or the
drive assembly and its shaft being damaged. Furthermore the drive assembly is
designed that in case the product flows back, the drive assembly and the rotor housing
do not bond together. With longitudinal play and the special design of the drive assembly
a perfect function is guaranteed.
When a disturbance occurs in a dispensing sequence:
– The dispensing sequence is interrupted.
– The rotorspray is switched off, possibly the advancing slide is switched to moving
backwards.
– The Loctite Controller signals an error message with a beeping tone (see Section 7).
