Starting the blender
Prior to starting the blender, carefully read the instructions in Section 4.
5.1.
START-UP
Carefully read Section 8.
. INOXPA will not be liable for improper use of the
equipment.
NEVER touch the blender or the lines if hot liquids are being pumped.
5.1.1.
Checks before starting the table blender
•
Completely open the shut-off valves on the suction and discharge lines.
•
If liquid does not flow towards the pump, fill it with the liquid to be pumped.
The blender must never turn dry.
•
Check that the direction of rotation of the motor is correct.
•
If the blender has double mechanical seal, check that the cooling circuit are connected.
5.1.2.
Checks when starting the table blender
•
Check that the blender is not making any strange noises.
•
Check if the absolute inlet pressure is sufficient to prevent cavitation in the blender. Check the curve to obtain the
minimum required pressure above the vapour pressure (NPSHr).
•
Control the discharge pressure.
•
Check for leaks in the sealing areas.
A shut-off valve shall not be used to regulate the flow in the suction line. All shut-off valves must be fully
open during operation.
Control the motor consumption to prevent an electrical overload.
Reduce the flow rate and the electrical power consumed by the motor:
•
By regulating the blender's discharge flow.
•
By decreasing the motor speed.
