Abstract
The invention discloses a thermocouple protective casing for an explosion-proof motor and relates to the technical field of the thermocouples. The thermocouple protective casing comprises a stainless steel inner pipe (1), a coil pipe (2), a stainless steel outer pipe (3) and a Cr3C2 metal coating (4); the coil pipe (2) is arranged between the stainless steel inner pipe (1) and the stainless steel outer pipe (3); the Cr3C2 metal coating (4) is formed on the stainless steel outer pipe (3) by virtue of spray coating. The coil pipe (2) is wound around the stainless steel inner pipe (1). The thermocouple protective casing for the explosion-proof motor is secure in structure and resistant to corrosion, and therefore, the service life of the thermocouple protective casing is greatly improved.
Description
Technical field
What the present invention relates to is thermopair technical field, is specifically related to a kind of fire proof motor thermocouple protective casing.
Background technology
Thermopair has become most widely used temperature-sensing element in the fields such as commercial production and scientific research.The property indices such as the performance impact thermopair long-time stability of fire proof motor use thermocouple protective casing material, serviceable life.But some thermopairs can be corroded in use, easily to damage, and be under pressure and be also easily damaged, intensity is low.
Summary of the invention
For the deficiency existing in prior art, the invention provides a kind of fire proof motor thermocouple protective casing, sound construction, corrosion-resistant, greatly improved its serviceable life, the preparation cost of its metallic coating and ceramic coat is low, and cost performance is high.
To achieve these goals; the present invention realizes by the following technical solutions: a kind of fire proof motor thermocouple protective casing; comprise stainless steel inner tube, coil pipe, stainless steel outer tube and Cr3C2 metallic coating; between stainless steel inner tube and stainless steel outer tube, be provided with coil pipe, on stainless steel outer tube, be coated with Cr3C2 metallic coating.
According to above-mentioned a kind of fire proof motor thermocouple protective casing, wherein, described coil pipe is coiled in stainless steel inner tube.
According to above-mentioned a kind of fire proof motor thermocouple protective casing, wherein, described Cr3C2 metallic coating is replaceable is B-Fe ceramic coat.
Sound construction of the present invention, corrosion-resistant, greatly improved its serviceable life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1; this embodiment is by the following technical solutions: a kind of fire proof motor thermocouple protective casing; comprise stainless steel inner tube 1, coil pipe 2, stainless steel outer tube 3 and Cr3C2 metallic coating 4; between stainless steel inner tube 1 and stainless steel outer tube 3, be provided with coil pipe 2, on stainless steel outer tube 3, be coated with Cr3C2 metallic coating 4.
Described coil pipe 2 is coiled in stainless steel inner tube 1.
Described Cr3C2 metallic coating 4 is replaceable is B-Fe ceramic coat.
The fire proof motor of this embodiment can at high temperature normally be worked by thermopair with thermocouple protective casing; and use in some Circulating Fluidized Bed Boiler; particularly under Rapid Circulation flow state; in the situation of High Temperature High Pressure and flue gas corrosion and erosion, also can normally work; its metallic coating and ceramic coat have good decay resistance, are applicable to the application of boiler high temperature position, and the preparation cost of metallic coating and ceramic coat is low; cost performance is high, practical.
This embodiment sound construction, corrosion-resistant, greatly improved its serviceable life.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
