Abstract
Disclosed is a low pressure plasma spray gun, comprising a nozzle, a waterway head, a gun body, a cathode pole, a cathode connector, an anode connector, an anode insulation part and a main gas joint. The utility model us characterized in that: the cathode pole is connected by tight junction with the cathode connector; the cathode part comprises a cathode insulator, an insulation rig and an insulating sleeve; the main gas joint is welded on lateral of the gun body. The utility model has the advantage of that: firstly, double insulation is realized through adoption of the cathode insulator(6) and insulation sleeve(10) which can guarantee the insulation distance between the cathode and anode and overcome the danger of outside arcing between cathode and anode; secondly, the cathode connector is thread connected with the anode pole to guarantee a good contact, which overcomes the shortcoming of contact arcing; thirdly, the main gas pipe communicates with the gun body form lateral to simplify the structure of the spraying gun, which improves the safety. Therefore, the utility model is safety and reliable by operation at low pressure.
Description
Technical field
The utility model relates to a kind of plasma gun that under low pressure uses.
Technical background
At present, the domestic plasma gun that uses of producing, be suitable under atmospheric conditions, using, if under low pressure, especially under argon gas atmosphere, between the negative electrode of plasma gun and the rifle body, under the high-frequency ignition effect, be easy to breakdown and beat arc, make the normally starting the arc between the negative electrode of rifle and the anode, thereby spray gun can be seriously damaged.
Summary of the invention
The purpose of this utility model is improved at the shortcoming in the background technology, provide use under a kind of low pressure under high-frequency ignition, be not easy breakdown plasma gun.The technical solution of the utility model is, it is made up of nozzle, water channel head, rifle body, cathode rod, negative contact, positive contact, cathode insulation spare and main gas joint, it is characterized in that cathode rod closely is connected with the negative contact employing, cathode insulation spare comprises cathode insulation body, dead ring and insulation sleeve, and main gas joint is welded on the rifle body side surface.
The utility model has guaranteed abundant insulation because cathode insulation body and insulation sleeve have drawn back the distance between negative electrode and the anode; Owing to adopted tight connection between cathode rod and the negative contact, guaranteed the excellent electric contact between them again; And owing to main gas joint is gone into main conductance from the rifle body side surface, thereby make simplifying the structure of rifle.
The specific embodiment of the present utility model is provided by the following drawings:
Description of drawings
Fig. 1 is the novel installation diagram of this realization
The specific embodiment
Nozzle of the present utility model and water channel head are 7M rifle universal standard parts, the utility model is made up of nozzle 1, water channel head 2, rifle body 4, cathode rod 3, negative contact 8, positive contact 11, cathode insulation spare and main gas joint 12, it is characterized in that cathode rod 3 closely is connected with negative contact 8 employings, cathode insulation spare comprises cathode insulation body 6, dead ring 9 and insulation sleeve 10, and main gas joint 12 is welded on rifle body 4 sides.
The cathode rod 3 rear end cars that closely are connected to described in the utility model have external screw thread and the female negative contact 8 of car to connect.Insulator 6 rear ends are provided with the hole of passing for cathode rod 3, and insulator 6 front ends are macropore path length cover, and negative contact 8 is positioned at this macropore path length cover with the threaded connection place of cathode rod 3.On the negative contact 8 front end external diameters dead ring 9 is housed, insulator 6 is threaded with nut 7, and compresses dead ring 9, and negative contact 8 centers are through hole.Insulation sleeve 10 centers are porose to be contained in the negative contact 8, and macropore path length cover covers nut 7, insulator 6, dead ring 9 and negative contact 8.Main gas joint 12 is welded in rifle body 4 sides, and main gas enters the cathode rod skin to nozzle 1 from rifle body 4.
Assembly technology of the present utility model: with cathode taps 15, be installed on the cathode rod 3 with screw thread, again front insulator 14 and back insulator 13 are enclosed within on the cathode rod 3, by sealing ring gas circuit and water route are separated, said modules is pressed in the water channel head 2, again anode nozzle 1 usefulness clamping nut 16 is contained on the water channel head 2, and then 1,2,3,13,14,15,16 assemblies of being formed are connected with the rifle body by the screw thread on the water channel head, positive contact 11, main gas joint 12 is welded on the rifle body, and cathode insulation body 6 is fixed by nut 5 and rifle body, and negative contact 8 is connected with cathode rod by screw thread, guaranteed to electrically contact good, put then and compress dead ring 9, compress dead ring 9 with nut 7 again, negative contact 8 is fixed, insulation sleeve 10 on the back cover is further insulating between negative electrode and the anode.
The utility model operation principle: the negative contact of low-voltage plasma spray gun is connected with the anode water-cooled cable with the negative electrode of power supply respectively with positive contact, main gas joint is connected with main gas tube, start plasma power supply, make negative positive electricity on cathode taps and the nozzle tape, connect main gas then, make between negative electrode and the anode by electrical apparatus control system and to produce high frequency, thereby generation electric arc, gas between anode and cathode is ionized, form plasma flame flow, the material that will spray is added in the flame stream, and fusing is ejected into and forms coating on the matrix surface.
The utility model has the advantages that: at first be to adopt cathode insulation body 6 and insulation sleeve 10 to realize double insulation, Guarantee the insulation distance of negative electrode and anode, overcome the extremely outside danger of beating arc of negative and positive; Next is that negative electrode connects Head is realized being threaded with the negative electrode bar, guarantees that contact is good, has overcome the shortcoming that arc is beaten in contact; The 3rd, main Tracheae is connected with the rifle body from the side, makes simplifying the structure of spray gun, and security has improved, so this practicality is new Type is under low pressure safe and reliable to operation.
