Abstract
The utility model discloses a sheathed bearing bush temperature thermal resistor which comprises a junction box and a thermocouple element, wherein the thermocouple element is a sheathed thermocouple connected by a thread, an O-shaped rubber ring is lined in the thread, and the sheathed bearing bush temperature thermal resistor further comprises a first-section support tube and a second-section support tube which both adopt full-thread regulation and are connected by a spliced cap, and an elastic element is connected onto one end, far away from the first support tube, of the second support tube. The sheathed bearing bush temperature thermal resistor is applicable to the bearing bush temperature of a large industrial water pump, the sheathed thermocouple is adopted, threaded connection in the field is implemented, the O-shaped rubber ring is lined in the thread, a sealed temperature measurement feeler lever is enabled not to leak oil, and the support tubes adopts full-thread regulation so as to well adapt to the temperature measurement points at different depths; the junction box is fixed with the support tubes by means of combination of turning up the support tubes and compressing the thread, the direction of an electric interface can be adjusted according to the field connection requirements, and meanwhile, the elastic element is arranged, so that mechanical vibration is attenuated during field service.
Description
Technical field
The utility model relates to a kind of temperature measuring instrument, is specifically related to the warm resistance of a kind of armouring bearing shell.
Background technology
At present, in industrial processes, particularly in the production run of oil-refining chemical, electricity power enterprise, the bearing shell of a lot of rotary system devices is arranged, particularly bearing shell, the thrust bearing shoe valve of large high-speed fan blower, steam turbine, compressor, cigarette machine etc. all need to use the Thermistor Temperature Measurement device to its thermometric.Original Thermistor Temperature Measurement device generally comprises thermal resistance, protective casing and draws wire, and protective casing is enclosed within outside the thermal resistance, draws wire and links to each other with thermal resistance.Original conductor structure of drawing wire employing outside metal screen layer wrapping inner layer tape insulation skin is drawn and is adopted the adhering with epoxy resin encapsulation between wire and the protective casing.Because the epoxy encapsulation part is oriental cherry very easily; and the vibration frequency of bearing shell, thrust bearing shoe valve is very high, draws wire therefore easily shake is disconnected under the high-frequency vibration, causes unit tile temperature measurement signal interruption; because unit thermometric and overhead control are interlocks, and then cause whole production line out of service.On the other hand, extraordinary reason owing to tile fragment, it is smaller that his temperature element is installed the aperture, and the wire of drawing the metallic shield net of wire and tape insulation skin is because making reason, its whole diameter can't be accomplished the installation aperture less than temperature element, drawing the whole termination of wire can not fill in the mounting hole of temperature element, therefore the lubricating oil in the unit can flow out unit by the space between wire and the space between wire and the metallic shield net, cause serious run, drip, leak phenomenon, affect the reliability of unit and thermometric, also affect environmental health.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of warm resistance of armouring bearing shell without leakage of oil and available buffer mechanical vibration.
For reaching this purpose, the utility model by the following technical solutions:
The warm resistance of a kind of armouring bearing shell, comprise terminal box and thermocouple element, its thermocouple element is armoured thermocouple, described armouring thermocouple is threaded connection, and described screw thread liner O type rubber ring, also comprise first, second two sections stay pipes, described first, second stay pipe adopts perfect thread to regulate, and described first, second stay pipe connects by piecing together cap; Described the second stay pipe is connected with flexible member away from an end of described the first stay pipe.
Described terminal box adopts the flange of stay pipe and the fixed form that collet threaded combines with described stay pipe.
The warm resistance of described armouring bearing shell that the utility model proposes is applicable to large scale industry water pump bearing insert temperature, adopt armoured thermocouple, the screw thread joint connection in site, and screw thread liner O type rubber ring, accomplish to seal the thermometric feeler lever without leakage of oil, stay pipe partly adopts perfect thread to regulate, and can well adapt to the point for measuring temperature of different depth; Terminal box and the fixed form that stay pipe adopts stay pipe flange and collet threaded to combine can be regulated the electric interfaces direction according to the field wiring demand, and band has elastic component available buffer mechanical vibration when using at the scene simultaneously.
