Background technology
In Chinese large-sized generator sets in power plant equipment, have the temperature of a lot of bearings, bearing shell, sidewall to need long-term, high-precision temperature survey, and the vibrations that this equipment runs are very large and require that inner full lubricating oil can not be revealed.The temperature sensor that generating plant adopted in the past adopts antidetonation cutting ferrule bolt arrangement or retaining thread hermetically-sealed construction usually, wherein adopt the temperature sensor of antidetonation cutting ferrule bolt arrangement after a period of operation internal lubrication oil cause leakage because of the seal failure of antidetonation cutting ferrule, the temperature sensor of retaining thread hermetically-sealed construction is adopted easily to cause the damage to sensor due to equipment vibrations, therefore these two kinds of structures are normally run all to unit equipment and are brought labile factor, and result of use is all undesirable.
Summary of the invention
For solving the problem, the invention proposes a kind of antidetonation Drain Resistance structure temperature sensor.
The technical scheme that the invention adopts is:
A kind of antidetonation Drain Resistance structure temperature sensor, from temperature sensor head, comprises: armouring fixed sleeving, lower nut and top nut successively, wherein:
There is temperature-sensing element described armouring fixed sleeving inside, and described temperature-sensing element comprises temperature-sensing probe and probe connecting line;
Described lower nut is connected with described armouring fixed sleeving, and described armouring fixed sleeving can to-and-fro movement in described lower nut with movement;
Described top nut is connected with lower nut, and described top nut afterbody is hollow-core construction, can connect terminal box or other structures as required;
Described armouring fixed sleeving is provided with Flexible Connector, described lower nut inside be provided with can make armouring fixed sleeving nested enter O-ring seal, between described lower nut and top nut, envelope has the first sealing, and described top nut afterbody envelope has the second sealing.In the mode of sealing, improve original dot encapsulation and linear sealing, adopt the sealing of oil resistance section, increase seal length, lubricating oil thoroughly can not be oozed out from temperature element (TE) measuring point, equipment long-time running is reliable and stable can not scrap.
Further, described Flexible Connector is elastic pressuring spring.
Further, described O-ring seal is silicon rubber.
Further, the quantity of described O-ring seal is at least 1.
Further, it is characterized in that: described armouring fixed sleeving reciprocating activity in described outer tube is 0-35mm.
Preferably, described armouring fixed sleeving reciprocating activity in described outer tube is 5-35mm.
Preferably, described armouring fixed sleeving reciprocating activity in described outer tube is 5-30mm.
The advantage that the invention has and good effect are:
In the mode of sealing, improve original dot encapsulation and linear sealing, adopt the sealing of oil resistance section, increase seal length, lubricating oil thoroughly can not be oozed out from temperature element (TE) measuring point, equipment long-time running is reliable and stable can not scrap.
Utilize two step antidetonation Drain Resistance methods of mobilizable cylinder piston principle and three grades of hermetically-sealed constructions (O-ring seal, the first sealing, the second sealing), achieve the antidetonation Drain Resistance function that device temperature measuring process requires.This product has excellent antidetonation Drain Resistance function, and the serviceable life of temperature sensor and measuring accuracy are obtained for effective guarantee.
