2. in order to ensure that vacuum sealing needs to press relatively tighter by rubber ring, resistance when moving in this way is just very big, can only
For adjusting opposite joint at a slow speed manually, to realize welding just needs the very powerful motor of outfit or gear when quickly moving
Sealing ring to be overcome to compress the very big resistance of motion generated, and be difficult to realize smoothly move, therefore for needing to carry out
Plane longitudinal direction（Y-direction）With transverse direction（X to）The part of welding must just design X-Y bilayers linear motion work in vacuum work room
Make platform, not only increase the cost of workbench, while the space of vacuum workshop must increase, also so as to the power of vacuum pump
It increases, causes a series of cost increase.
It 3., can not be to sealing during use since the structure of the usual mechanism of the requirement in vacuum sealing and space is extremely compact
The motive position of circle is lubricated, and with the extension of usage time, sealing ring can be increasing to the friction of moving surface, until needing
Disassembly mechanism is wanted to replace sealing ring.
4. since electron gun needs to be moved longitudinally, it is therefore necessary to output the Kong Rang electricity of elongated in vacuum work locular wall
Beamlet passes through, and the X ray in such welding process is just easy to come out from each slot leakage of motion, it is necessary to be taken in outside
Safeguard procedures prevent the leakage of X ray.
