Attaching The Horn to a Booster, Booster to a Probe, or Horn to a Probe

1.Inspect all surfaces to be joined for stress cracks, chips, or gouges. Any of these irregularities will affect operation and could lead to further equipment damage. Contact the Dukane Ultrasonic Tooling Department concerning a damaged booster.

2.Ensure that the mating surfaces of the two components are clean and smooth. These surfaces must make inti- mate contact for the mechanical energy to pass from one component to the next. Pitting or a buildup of old grease and dirt on a mating surface will interfere with the energy transfer and reduce the power delivered.

3.Make sure that the stud in the horn or booster is tight. See the preceding mounting stud assembly instructions for torque specifications.

4.Remove any foreign matter from the threaded stud and mating hole.

5.Apply an extremely thin layer of a high temperature, high pressure silicon grease to the surface that mates with the horn. The grease will allow both surfaces to intimately mate and become acoustically transparent which improves the energy transfer. We recommend Dow–Corning #4 (or #111 as an alternate). A small packet of Dow–Corning #4 is supplied with the system. If you cannot use a silicon–based grease in your facility, a petroleum–based grease may be used. However, it is likely to leave carbonaceous deposits on the surface, and require more frequent joint maintenance. Grease may be omitted if mylar washers are preferred on sys- tems that require frequent changes. Mylar is plastic and will creep under compression, so mylar is not recom- mended for system that are not changed frequently. Failure to follow these instructions, may result in the mating surfaces bonding and difficulty removing the horn from the booster or the booster from the probe.

NOTE

Always remove a probe stack from the machine in which it is mounted before attaching or removing a horn.

CAUTION

Never leave a horn or booster assembly hand tight. Torque it to the proper specifications before proceeding. If the as- sembly is installed without being properly torqued down, the assembly may vibrate severely, damaging the mat- ing surfaces and causing the generator to overload.
