Abstract
The present invention relates to a kind of installation methods of explosion-protection equipment; this installation method connects explosion-protection equipment and workpiece using welding procedure; realize sealing performance; cooling medium is poured at explosion rupture disk; the mode that cooling medium can absorb the logical heat transfer of the heat generated when welding is transmitted to the temperature in explosion rupture disk; so that the temperature of explosion rupture disk is lower than its critical-temperature that can bear, the explosion-proof performance of explosion rupture disk is protected with this.
Description
Technical field
The present invention relates to a kind of installation method of explosion-protection equipment more particularly to the installation methods of breaker explosion-protection equipment.
Background technique
Breaker is a kind of Protector for electric appliances with the multiple protection functions such as overcurrent, short circuit, electric leakage, under-voltage, overheat.
Not only structure is complicated for most of breakers, performance reliability is poor, but also shell is usually the plastic housing of non-tight, it is difficult to meet
Explosion-proof, dust-proof, waterproof specific demand.Therefore explosion-protection equipment is all installed additional on the breaker that domestic enterprise uses, and traditional is explosion-proof
Device includes tubular shell, and one end of tubular shell is equipped with connecting flange, and connecting flange with breaker for connecting, connecting flange
The joint face connecting with breaker is equipped with sealing ring.This explosion-protection equipment when in use, when due to circuit breaker internal power on/off
There are a large amount of fevers, temperature is higher, will lead to sealing ring aging, loss of seal effect after a period of use.
Recently there is a kind of novel explosion-protection equipment to occur in the market, mainly include tubular shell, explosion rupture disk is mounted on cylinder
In shape shell, one end outer peripheral surface of tubular shell is equipped with welding groove, and this explosion-protection equipment is connect by welding with breaker
And realize hermetic seal.However, often will cause when by tubular shell welding on-board the circuit breaker due to the thinner thickness of explosion rupture disk
Welding heat is transmitted in explosion rupture disk and then the structure property of explosion rupture disk is caused to change, and directly affects the resistance to pressure of explosion rupture disk
Energy.Therefore, the installation of this explosion-protection equipment just becomes the puzzlement of assembly crewman.
Summary of the invention
The purpose of the present invention is to provide a kind of installation method of explosion-protection equipment, solve on breaker through the side of welding
The problem of method installs explosion-protection equipment, increases explosion rupture disk temperature, and structure property changes, and reduces explosion rupture disk pressure resistance performance.
To achieve the above object, the technical solution of the installation method of explosion-protection equipment of the present invention is: a kind of peace of explosion-protection equipment
Dress method, workpiece are aligned with explosion-protection equipment and pass through welded connecting, and cooling is added in the explosion rupture disk in welding in explosion-protection equipment
Medium.
Further, the cooling medium is cooling water.
Further, explosion rupture disk is completely covered in the cooling water.
Further, the welding method is laser welding.
Further, the technological parameter of the laser welding are as follows: focal length 300mm, defocusing amount+60mm, power 2500W, light
Spot diameter 3mm, speed of welding 1.5m/min.
The beneficial effects of the present invention are: in connection explosion-protection equipment by welding and workpiece, in explosion-protection equipment
Cooling medium is poured into explosion rupture disk, cooling medium can absorb the energy passed in welding by explosion-protection equipment shell,
Without increasing the temperature of explosion rupture disk too much, to guarantee that explosion rupture disk structure property is intact.Improve product quality and competition
Power reduces production cost.
Further, cooling medium uses cooling water, has saved cost, and do not pollute the environment.
Further, explosion rupture disk is completely covered in the cooling water, can preferably absorb and to pass in welding process
Energy.
Further, keep the deformation of welded part and protective casing minimum using laser welding, and the weld seam after welding
Almost without gap, the intensity of good seal performance, and weld seam is much larger than explosion-proof pressure.
Detailed description of the invention
Fig. 1 is that explosion-protection equipment of the invention welds schematic diagram;
Fig. 2 is explosion-protection equipment top view of the invention;
Fig. 3 is the sectional view of explosion-protection equipment main view of the invention.
Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment one of the installation method of explosion-protection equipment of the invention, as shown in Figure 1 to Figure 3, explosion-protection equipment 7 includes
The bottom end of protective casing 3 is arranged in protective casing 3 and explosion rupture disk 6, explosion rupture disk 6, and distance is external farther out, since explosion rupture disk 6 is relatively thin,
It is set to be not readily susceptible to accidentally touch and cause deformation or damage to it.There is cooling water 4 in the upper end of explosion rupture disk 6, and cooling water 4 can be inhaled
The energy passed over from protective casing 3 when welding is received, and subtracts the energy being transmitted in explosion rupture disk 6 by protective casing 3
It is few, therefore the temperature of explosion rupture disk 6 will not increase too much.One end on protective casing 3 far from explosion rupture disk 6 is equipped with step 8, step
8 can match with workpiece 5, facilitate the welding of workpiece 5 Yu explosion-protection equipment 7, and step 8 makes in one end far from explosion rupture disk 6
The distance conducted heat on protective casing 3 when welding is longer, the more difficult raising of the temperature of explosion rupture disk 6, to protect in welding
Explosion rupture disk 6.
It is first that 5 removing surface of workpiece is clean specifically, in embodiment, then using tooling make the inner headed face of workpiece 5 with
The step 8 of protective casing 3 is fixed together, and pours into cooling water 4 in the explosion rupture disk 6 in explosion-protection equipment 7, finally carries out Laser Welding
It connects, laser welding process parameter are as follows: focal length 300mm, defocusing amount+60mm, power 2500W, spot diameter 3mm, speed of welding
1.5m/min, perpendicular to the junction of workpiece 5 and step 8, the weld seam 2 after the completion of welding almost do not have the laser beam 1 that laser issues
There is gap, ensure that the air-tightness of explosion-protection equipment 7, and the intensity of weld seam 2 is much larger than explosion-proof pressure.Complete welding explosion rupture disk and
Cooling water temperature is about 25 DEG C, is far below explosion temperature, explosion rupture disk is intact.
The embodiment two of the installation method of explosion-protection equipment of the invention: with embodiment one the difference is that, it is described cold
But medium is coolant liquid.
The embodiment three of the installation method of explosion-protection equipment of the invention: with embodiment one the difference is that, the weldering
Connecing mode is electron beam welding.
When the installation method of explosion-protection equipment of the invention connects explosion-protection equipment and workpiece by welding, in explosion-proof dress
Cooling medium is poured into the explosion rupture disk set, cooling medium can absorb the energy passed in welding by explosion-protection equipment shell
Amount, it is too many without increasing the temperature of explosion rupture disk, to guarantee that explosion rupture disk structure property is intact.
