7. Troubleshooting
The following table provides solutions to problems that might arise during the operation of the blender.
The blender is assumed to have been properly installed and be suitable for the relevant application.
Please contact INOXPA if technical assistance is required.
The blender does not suction
Insufficient pressure on impulsion
Motor overload
Noise
Vibrations
Leaks
PROBABLE CAUSES
SOLUTIONS
•
Wrong motor rotation direction
Reverse the motor rotation direction
•
Very high powder percentage
See chapter 4. General Information
•
Very high temperature
Reduce temperature
•
• Worn mechanical seal
Replace the blender mechanical seal and/or su-
pply pump mechanical seal
•
Differential pressure is too high
Reduce pressure. See chapter
4. General Infor-
mation
•
The suction pressure is too high
Reduce suction pressure. See chapter
4.
General Information
•
Insufficient liquid
Check the supply pump
•
Viscosity product or delivery height is too high
Reduce the viscosity, e. g. by heating the fluid
•
Worn motor bearings
Replace bearings as indicated on the manufac-
turer instruction manual
• •
Foreign bodies inside the blender
Disassemble the blender and remove the
foreign bodies. Verify the housing, the impeller
and the mechanical seal
•
The blender is not at the right level
Correct the level and the alignment of the
blender
•
The impeller is damaged
Replace the impeller
•
Blender cavitation
Reduce the pressure drop on the suction or use
a suction pump
•
O-rings inadequate for the fluid
Mount the correct O-rings consulting previously
with the supplier
• Spring mechanical seal tension is too low
Adjust according to the Instruction Manual
• Clamp is loose
Tighten the clamp
•
The blender suction little dust
Check tha the zone of the valve and the bottom
of the hopper are not dry
Increase the flow of the hopper
• Fluid loss by the hopper
Decrease the liquid heigh of the suction tank
In pressurized tanks, reduce the internal pres-
sure of the tank
• •
•
Presence of air in the pipe
Check that the air is not entered by the hopper
avoiding having the valve opened when the
solids entering the venturi is finished
