Bimetallic thermometer how to repair the damage? How to use correctly?

In the summer, no matter where, thermometer is used most, such as, bimetallic thermometer, bimetallic thermometer was damaged? Generally appear what problem? In general, bimetallic thermometer common fault mainly include: no precision, oil gas leak, pointer jump needle, needle loose, dial, glass table cover damage, etc. , bimetallic thermometer if damaged, we have to replace the new table is given priority to, if produce such as oil leakage, flaw can be generally returned to the factory maintenance, of course, these problems are because of the loss caused by improper operation or normal in the process of using, so we in the use of bimetallic thermometer is be used in accordance with the specifications, and regular inspection and maintenance, to ensure that the bimetallic thermometer display accurate, reduce the cost in production. Bimetallic thermometer in use there are many considerations, can accurately test and prolong the service life of the below small make up to introduce the use of the bimetallic thermometer and maintenance. (1) in order to guarantee the correctness of the thermometer, the depth of the heat tube immersed medium depending on the different heat pipe length should be within the range of 95 ~ 130 mm (2) readings implementation should be vertical (3) and dial thermometers (after normal use Generally no more than one year) Shall be carried out according to the relevant test procedures of the industrial bimetallic thermometer calibration on a regular basis. (4) heat thermometer encountered in the use process need to replace the damaged, simply loose nut counterclockwise, then turn the tables, cases in equipment, then the new table core loading, don't make double metal spiral tube and at the bottom of the case, screw nut. (5) the thermometer in the transport, storage, installation, use should be avoided in the process of collision, including table, heat pipe, pan, causing bad or sensitivity and precision of the thermometer is inaccurate. 6. The normal work condition of bimetallic thermometer is: ( - 25-85) ° C, relative humidity between 5% ~ 100%. Therefore, the correct use of thermometer can not only prolong the life of the thermometer, and can reduce economic losses, also can reduce the trouble at work!
