Blowing hose for UV CIPP cure equipment used for trenchless repair
sewers
Turn on the blower and gradually increase the power of the blower
to make the hose expand and fully open to ensure that it will not
wrinkle after curing. Start the main engine and observe the
pressure change.
The simple process of blower pressurization is as follows
(depending on the material supplier):
Startup process: turn on the generator (before the blower is turned
on), and then turn on the main power supply. Then the equipment:
turn on the two emergency stop switches and turn on the power
supply of the equipment. In the operation interface, long-press the
video button to turn on the computer and turn on the run button.
Then open the video software. (reverse the shutdown process)
Then gradually increase the blower power, maintain the pressure,
and start curing about 15 minutes after reaching 300mbar. Ensure
that the whole pressure maintaining process lasts about 40 minutes.
Precautions for inflation:
The inflation time and pressure holding time shall be determined
according to the temperature of the laminate, the thickness of the
lined hose, and the shape of the pipe. Especially in winter when
the temperature is low or the wall thickness of the material layer
is too thick, as well as in the case of special-shaped pipes, it is
necessary to extend the pressure keeping time by 15 minutes.
When the air pressure is insufficient, the material will not be
fully stretched and the thickness will be uneven. When the lamp
holder is driving, it may be blocked due to the uneven material and
tear the inner membrane; Or there are too many resins and too few
glass fiber layers at the material stack, which will affect the
elastic modulus after curing.
If the air pressure is too high, the binding cover plate may fly
out and the binding cloth may collapse; If there are dislocations,
disjoints, and holes in the pipeline, the lining material may
burst.
