10.
At tach the tub ing nip ples to these tub ing ends. If the tub ing is stain less steel at the ends, use TIG
weld ing to at tach the nip ples.
11.
Coat the O-ring with Apiezon L grease and re place it in the groove in the air/wa ter feedthrough.
12.
Re in stall the feedthrough-tub ing as sem blies, tight en ing the feedthrough’s fix ing nut all the way this
time.
13.
Be gin screw ing the con nect ing nuts on the tub ing ends onto the threaded un ions on the gun’s wa ter
lines. You should be able to do so with out putt ing any ten sion on the feedthrough’s in-vac uum tub -
ing. If mak ing this con nec tion re quires ap ply ing any force to this tub ing, re ad just the bends in the
lines to elim i nate all ten sion on the tub ing.
14.
Make the at mo sphere-side con nec tions for the wa ter sup ply and re turn lines. If you are us ing the
hard ware avail able from Temescal, first con nect the rub ber fer rules to the 45°
×
1/4" NPT flare con -
nec tors. Then con nect the fer rules to the at mo sphere-side tubes of the wa ter feedthrough. Finally,
con nect the barbed hose con nec tors to the sup ply and re turn hoses and screw the barbed con nec tors
onto the flare con nec tors con tained in the air sys tem kit PN 0627-3010-0.
15.
Make the at mo sphere side con nec tions for the air sup ply and re turn lines us ing the parts.
CAU TION 1
To ensure proper cooling, the water lines MUST be connected as
shown in Figure 2-1, with the supply line connected to the gun’s
lower external water junction and the return line connected to the
gun’s upper external water junction. The crucible will not be cooled
adequately if these connections are reversed.
CAU TION 2
When connecting the three 1/8” SST tubes from the feedthrough to
the gun, the vent line, which is the line immediately terminated on
the atmosphere side of the feedthrough, must be connected to the
vent line of the air cylinder. The “V” in the clamp block denotes the
vent line.
NOTE
Connecting the vent line to a source of pressurized air will result in
damage or failure of the bellows on the air cylinder.
Pro ce dure 4: In stall the Tur ret-Drive Com po nents
1.
If you are mount ing a side-drive source, in stall the ro tary-mo tion feedthrough at this time. If you are
in stall ing a bot tom-drive source, skip this step and step 2 and pro ceed to step 3.
2.
Con nect the gun’s drive shaft to the ro tary feedthrough’s out put (i.e., vac uum-side) shaft. On
side-drive sources, you may need to add an ex ten sion shaft like that shown in Fig ure 2-1 be tween the
gun’s drive shaft and the ro tary feedthrough. Con necting a side-drive source to a ro tary feedthrough
mounted in the source tray will re quire a right-an gle cou pling. In all other cases, use a flex i ble
in-line cou pling (PN 9015-0121-0) to con nect the shafts.
