Utility model content
The purpose of this utility model is to solve above-mentioned technical matters, proposes a kind of multi-measuring point armoured thermocouple device being applied to aeromotor.
The purpose of this utility model, to be achieved by the following technical programs: a kind of multi-measuring point armoured thermocouple device being applied to aeromotor, described multi-measuring point armoured thermocouple device is arranged in the peripheral pipeline of aeromotor, especially, described multi-measuring point armoured thermocouple device comprises armoured thermocouple main body, socket and plural thermode, the bore of the peripheral diameter of described armoured thermocouple main body and the peripheral pipeline of aeromotor matches
Described armoured thermocouple main body is provided with the axial installing tache of plural number for fixing armoured thermocouple main body and plural number circumference installing tache;
Described thermode comprises thermode sleeve pipe, lining, mount pad and adapter by bottom to end and chews, and described thermode sleeve pipe is connected with armoured thermocouple main body;
Described socket is made up of base and cover plate, and described cover plate has slot, and the both sides of described base are equipped with receptacle ferrule, and described receptacle ferrule is connected with armoured thermocouple main body.
Preferably, described axial installing tache and circumferential installing tache all have rivet hole.
Preferably, described base is provided with the fixing rivet hole for fixed socket.
Preferably, described mount pad is connected for argon arc welding between chewing with adapter, described lining be argon arc welding between thermode sleeve pipe and mount pad and be connected, be brazing between described thermode sleeve pipe and armoured thermocouple main body.
Preferably, described axial installing tache and be brazing between axial installing tache and armoured thermocouple main body.
The beneficial effects of the utility model are mainly reflected in:
Compared with traditional multi-measuring point thermocouple structure, there is dress convenient, greatly reduce maintenance time; Compact conformation, lightly; There is good environmental suitability; Life-span is high, and reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional multi-measuring point thermopair.
Fig. 2 is a kind of structural drawing being applied to the multi-measuring point armoured thermocouple device of aeromotor of the utility model.
Embodiment
The utility model provides a kind of multi-measuring point armoured thermocouple device being applied to aeromotor, multi-measuring point armoured thermocouple device is arranged in the peripheral pipeline of aeromotor, multi-measuring point armoured thermocouple device comprises armoured thermocouple main body, socket 11 and plural thermode 5, there is in armoured thermocouple main body the thermo wires by socket and the series connection of plural thermode, the bore of the peripheral diameter of armoured thermocouple main body and the peripheral pipeline of aeromotor matches, armoured thermocouple main body is provided with the axial installing tache 6 of plural number for fixing armoured thermocouple main body and plural number circumference installing tache 7, axial installing tache and be brazing between axial installing tache and armoured thermocouple main body.Thermode 5 comprises thermode sleeve pipe 4, lining 13, mount pad 3 and adapter by bottom to end and chews 14, and thermode sleeve pipe 4 is connected with armoured thermocouple main body; Mount pad is connected for argon arc welding between chewing with adapter, lining be argon arc welding between thermode sleeve pipe and mount pad and be connected, be brazing between thermode sleeve pipe and armoured thermocouple main body.Socket 11 is made up of base 10 and cover plate 12, and cover plate 12 has slot, and the both sides of base 10 are equipped with receptacle ferrule 9, and receptacle ferrule 9 is connected with armoured thermocouple main body.
For increasing fixed speed and fix tightly soundness, adopt the mode of rivet to fix armoured thermocouple main body and socket, axial installing tache and circumferential installing tache all have rivet hole 8, and base is provided with fixing rivet hole.
Below a kind of concrete shaping manufacturing process being applied to the multi-measuring point armoured thermocouple device of aeromotor of the utility model: because the peripheral pipeline of aeromotor is complicated, so the bending circuit of armoured thermocouple main body need be designed by three-dimensional software, carry out moulding according to bending circuit to armoured thermocouple main body.Carrying out a series of welding operation, mount pad is chewed with adapter and is connected by argon arc welding, sleeve pipe and armoured thermocouple main body pass through brazing, thermode sleeve pipe is connected by argon arc welding with lining, lining is connected by argon arc welding with mount pad, axial installing tache and circumferential installing tache pass through brazing with armoured thermocouple main body, cover plate and base argon arc welding etc.200 object electrically molten magnesia powder are finally selected to be fixed sealing to multi-measuring point armoured thermocouple device, due to magnesia powder possibility moisture absorption during powder filling, during argon arc welding sealing cover plate, first sealing 3/4 cover plate, is then placed in 250 DEG C of baking oven inside holding by assembly, and rear taking-up to be dried is sealing residue weld seam immediately.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
