Start-Up Procedure
Note:
Prior to Start-Up, carefully read the Check List on the preceding pages!
Note:
Prior to start-up, the Acoustic Intensity Meter Operating Manual MUST be read.
1. Make sure power is OFF and that the unit is electrically grounded.
2. Check that the fluid to be processed is compatible with the "O" ring seals and pump.
3. Flush the unit with water or an acceptable solvent as follows:
•
Remove the Orifice.
•
Retract the Blade from the orifice by rotating the Calibrator Handle and fully open the Tuning Valve by turning the
Tuning Valve Handle, (mounted at Sonolator OUTLET).
•
Fill the funnel or feed Vessel/Tank with water or solvent.
•
Start the pump and run the water or solvent out of the funnel or recycle it for a few minutes, if desired. Avoid
running the pump dry for more than a second or two.
4. Select the proper Orifice to yield the desired pressure. Remember, it's usually better to start with a larger orifice
(lower pressure) unless you are sure of the fluid characteristics and properties. Install the Orifice and its O-ring.
5. Pour a sufficient amount of premixed fluid into the funnel or open the feed line valve as appropriate.
6. Start the pump and observe the pressure gauge. If it is higher than it should be for a given orifice, check to make
sure that:
a.
The back pressure valve is completely open.
b.
The blade is retracted from the orifice.
c.
The filter is not clogged.
d.
The orifice is not plugged.
e.
The flow rate is correct and matches criteria given when Orifice was ordered and sized
Check
the
Troubleshooting Pressure Problems
portion of this manual as well; found in the
Procedures section
If all checks are in order, the orifice pressure can be lowered by using a larger orifice or reducing the pump
revolutions, as appropriate.
7. When the desired pressure is established, the Acoustic Meter should be turned on and the unit tuned as follows:
•
Move the blade into the jet stream until it is 2 or 3 turns of the adjusting wheel from the orifice.
•
Increase the back pressure by closing the Back Pressure Valve slowly. An audible sound ranging from a rushing
noise to a high pitched whistle should begin to develop. There will be a corresponding rise in the needle on the
acoustic meter and it will probably be necessary to adjust the meter gain control to keep the needle "on scale."
Continue turning the back pressure valve until the needle peaks or levels and begins to decline. Then return the
valve to the highest meter reading. BE CAREFUL NOT TO CLOSE THE VALVE COMPLETELY.
Caution:
Do not use the Back Pressure Valve to generate pressure. For the Sonolator
to work efficiently, all the
pressure must be generated solely by the Orifice. If the proper pressure is not generated by the Orifice provided
with the Back Pressure Valve completely opened, contact Sonic Corporation.
