How does acoustic cleaning work?

admin — Mon, 29 Nov 2010 10:25:43 +0000

Acoustic cleaner causes a sound pressure pulse which will detach the particles from the surfaces. The deposits adhering to the surface are subjected to a force greater than that retaining it. The particles with different masses are subjected to alternating sound waves. Because the particles have diffrent masses, the distance they travel is a little different. When the sound impact is repeated with appropriate frequency the particles go out of phase with each other and break appart. The required frequency of impacts depends on the amount of deposits, their natural vibration frequensy and adheviness. When the impact on the deposit is frequent enough, the deposit comes of and the surface is clean.

What kind of maintenance do the acoustic cleaners require?

admin — Mon, 29 Nov 2010 06:26:31 +0000

Compressed air driven acoustic cleaners do not need a lot of maintenance. However, the maintenance is very important to the best efficiency of the cleaner.
When the membrane of the generator is worn it has to be turn over or changed. If the sound pressure of the cleaner decreases 3 dB the sound power level is cut to half.
The generator contact surfaces also have to be re-machined. This does, however, not have to be as frequently as the change of membrane.
NSCD doesn’t also need a lot of maintenance. The condition of the gas valves and all the gaskets have to be regularly checked and the igniters have to be change in a certain period of time.

What is the air quality requirement for acoustic cleaners?

admin — Mon, 29 Nov 2010 06:25:23 +0000

The acoustic cleaner uses normal work air. The valve group of the cleaner has a filter/water separator to take out the impurities and water out of the work air.

What kind of gas does the NCSD® use?

admin — Mon, 29 Nov 2010 06:24:50 +0000

The NCSD® uses LP gas usually propane. The supply pressure of the gas is 2…4 bar

What is the gas and air consumption of NCSD®?

admin — Mon, 29 Nov 2010 06:24:10 +0000

NCSD® can make 1…15 pulses per second. One pulse uses about 0.4g of gas per pulse. In addition NCSD uses circa 80 Ndm3 of compressed air while running for burning air and cooling.

What is the required air supply pressure for the acoustic cleaners?

admin — Mon, 29 Nov 2010 06:23:36 +0000

The air supply pressure should be 6 bars. While sounding the pressure can decrease to 4 bars.

What is the air consumption of Nirafon acoustic cleaner?

admin — Mon, 29 Nov 2010 06:23:07 +0000

NI250ss and NI250ss/90: 20 Ndm3/s while sounding and 2 Ndm3/s continuously for cooling of the horn.
NI100ss and NI100ss/90: 40 Ndm3/s while sounding and 2 Ndm3/s continuously for cooling of the horn.
