6.1 - FAULTY MIX
A wrong mix or a very long pause can cause a blockage
inside the material hose; no mortar comes out from the
spray gun and the material pressure gauges shows a
pressure that is superior to the normal working pressure.
The “normal working pressure” depends on the material
and on the hoses that you are using; it is advisable to read
regularly this data on the material pressure gauge in order
to be able to promptly point out eventual anomalies.
In this case stop the pump by pressing the button
ON/
OFF (e1)
.
Release the pressure in
the material delivery hose
by running the pump at
reverse for a few seconds:
reverse the rotation of the
pump by pressing the
button
ON (e2)
.
Try to re-start.
Keep the working pressure under control and stop the
machine instantly if the pressure goes beyond the normal
value.
This would mean that the hose is still blocked.
Stop the pump and release the pressure in the material
delivery hose by running the pump at reverse
(e2)
for a
few seconds.
Always release the pressure from the hoses by
running the pump at reverse for a few seconds
(5 ÷ 10) before disconnecting them.
The material pressure gauge pointer must show a pressure
of 0 bar.
The operator must be carefully trained before
doing this operation.
Before the opening of a coupling, check that there is no
pressure inside the hoses and that no one stands too
close to the hoses.
This operation, that could be dangerous, must be carefully
carried on by qualifi ed personnel.
Stop the pump.
6 - TROUBLE SHOOTING
Find out where the material hose line is plugged; in this
point the hose is hard and rigid.
The most critical points are near the couplings.
Disconnect the plugged hose,
hit with an hammer near the
extremity of the plug to break the
“plug” until the hardened material
comes out.
Start the pump for a few moments and make sure that
the hose is free from “plugs”; the material comes out
normally.
Pour some cement slurry inside the hose before the point
where you had found the “plug”, connect the hoses and
start working again. If the material left inside the hopper is
not pumpable you must empty it.
Stop the pump by pressing the button
(e1)
, open the grill
in the hopper and fi x it with its hook; empty the hopper
with a trowel.
Open the hopper tap and with a water jet wash all the
material out. Hence close the tap, lower and fi x the grill in
the hopper, make the correct mix and start again. A stator
that is not properly might not push the material to the gun
or it might create a blockage at the beginning of the hose
by overheating the material.
In this case the pressure shown by
material pressure gauge
(37)
is the
working pressure.
It is necessary to set the stator
(page 17).
If during work the material surges at the delivery hopper,
check that there is material inside the hopper.
