Description
Technical field
The present invention relates to frame for movement technical field; Particularly relate to a kind of high pressure welding chamber signal of telecommunication thread guide devices and high pressure welding chamber.
Background technology
Hot-working method conventional in electroplating equipment wielding machine processing.Some parts are had to need the welding of particular surroundings, as under high pressure welded, at this moment need to weld in high pressure welding chamber, high pressure welding chamber ensures also to require that operating personnel can operate in cabin out of my cabin while there is certain air pressure inside at needs, and this just has the lead-in wire of the signals of telecommunication such as welding gun power line, operation signal line and signal monitoring cable to need to pass from cabin body.The sealed insulation mode of conventional gum cover is not seal bad to be exactly that insulation has problem, to affect the normal use of equipment.
Hyperbaric welding test chambe is exactly a kind of high pressure welding chamber, is mainly used in the simulated experiment of high pressure separate injection.
Although underwater welding method is a lot, according to the water proof degree of welding process welding region, generally underwater welding method is divided into three major types, i.e. wet method Underwater Welding, dry method Underwater Welding and local dry underwater welding.Dry method Underwater Welding is divided into again high pressure separate injection and normal pressure dry method Underwater Welding, although high pressure separate injection can get rid of the direct impact of water on welding process completely, but equipment is complicated, the preparation of construction time is long, support staff is many, construction cost is higher, and can not eliminate the impact of depth of water environmental pressure.Normal pressure dry method Underwater Welding can get rid of the impact of water depth pressure completely, and welding process is identical with land welding, but equipment is more complicated than high pressure separate injection, and construction cost is also higher, and therefore, normal pressure dry method underwater welding technology is seldom applied at present.
High pressure separate injection is the most widely used technology in important feature, pipeline rehabilitation, it is as the engineering half-way house between wet method Underwater Welding and normal pressure dry method Underwater Welding, overcomes wet environment and the normal pressure dry method Underwater Welding middle deck inside and outside differential pressure of wet method Underwater Welding.Be welded on one only need to resist compared with small pressure difference, carry out in sealed welding chamber that material weight is relatively light, welding chamber maritime interior waters is discharged by gases at high pressure, gas is equal at the pressure of interface with seawater, this interface is near the bottom in cabin, maximum pressure reduction is then positioned at the top in cabin, and its internal pressure exceedes external pressure approximately only several bar at zero point (bar).Adopt lightweight steel construction, simply flexible sealing to be just easy to solve this pressure reduction problem, thus make the installation in cabin and the operation of sealing become possibility.
High pressure separate injection technically Problems existing is that welding process must bear the environmental pressure corresponding to the depth of water.Hyperbaric environment all can have an impact to series of problems such as welding arc, Welding Metallurgy, welding procedures.The main purpose of high pressure separate injection research, for any specific environmental pressure and gas componant, how to determine suitable welding conditions, to ensure that welding quality meets relevant standard.
Carry out high pressure separate injection experiment generally all to need to build complicated analogue experiment installation, meanwhile, in analogue experiment installation, also can carry out welding procedure qualification test.The main body of analogue experiment installation is exactly hyperbaric welding test chambe.
Hyperbaric welding test chambe must can meet following requirement:
1, can simulate in cabin and maintain the gaseous environment that pressure corresponds to the concrete depth of water, namely can realize reliably high-pressure gas seal;
2, high pressure weld job can be carried out in cabin;
3, high pressure welding procedure can be controlled by the staff be in outside experimental cabin;
4, can by the weld seam in welding process and arc image information transmission to out of my cabin for researcher;
5, can monitor etc. the situation such as temperature, humidity, change of component of gaseous environment in welding process pilot scale hatch checking.
Just must use a large amount of cable penetrating devices, to solve the transmission of various strong and weak electricity signal inside and outside high pressure welding chamber between different pressures environment or transmission problem for this reason.
