Nine, installation requirements:

；應(yīng)注意熱電偶的安裝使用中的幾個細(xì)節(jié)

；有利于測溫準(zhǔn)確,安全可靠及維修方便,而且不影響設(shè)備運行和生產(chǎn)操作.要滿足以下要求,在選擇對熱電偶的安裝部位和插入深度時要注意以下2點:">The thermocouple installation should pay attention to details; several thermocouples were installed in use; for the temperature measurement is accurate, safe and convenient maintenance, and does not affect the equipment operation and production operation. To meet the following requirements, in the choice of the thermocouple installation position and insert depth should pay attention to the following 2 points:

。">1, with a protective casing thermocouple heat transfer and heat loss, in order to reduce the measurement error, the thermocouple should have sufficient depth of insertion.

、當(dāng)測量原件插入深度超過1m時,應(yīng)盡可能垂直安裝,或加裝支撐架和保護(hù)套管。">A, when measuring the original insertion depth is more than 1m, should be installed vertically, or installing supporting frame and a protective sleeve.

、假如需要測量是煙道內(nèi)煙氣的溫度,盡管煙道直徑為1000mm,熱電偶插入深度500mm即可

。">B, if you need to measure the flue gas temperature is, while the flue diameter is 1000mm, the depth of the thermocouple insert 500mm.

。">C, for the temperature measurement of fluid pipe center thermocouple, generally the measuring end is inserted into the pipe center (vertical or inclined installation). If the measured fluid pipe diameter is 100 mm, the depth of the thermocouple insert should choose 50~100 mm (should take into account the size installation base or flange).
、對于高溫高壓和高速流體的溫度測量（如主蒸汽溫度）,為了減小保護(hù)套管對流體的阻力和防止保護(hù)套管在流體作用下發(fā)生斷裂,可采取保護(hù)管淺插方式或采用熱套式熱電偶.淺插式的熱電偶保護(hù)套管,其插入主蒸汽管道的深度應(yīng)不小于75mm;熱套式熱電偶的標(biāo)準(zhǔn)插入深度為100mm。">D, for temperature measurement of high temperature and high pressure and high speed fluid (such as main steam temperature), in order to reduce resistance to the fluid and prevent the protective sleeve to protect the casing fracture under the influence of the fluid, can take the protection tube or shallow inserted by thermal sleeve type thermocouple. Shallow inserted thermocouple protection tube type, which is inserted into the main steam pipeline the depth should be less than 75mm; thermal sleeve type thermocouple standard insert depth 100mm.
、為了使熱電偶的測量端與被測介質(zhì)之間有充分的熱交換,應(yīng)選擇合理測點位置,盡量避免在閥門,彎頭及管道和設(shè)備的死角附近裝設(shè)熱電偶

。">2, in order to make the measurement end of thermocouple and measured with sufficient heat exchange medium, should choose a reasonable measuring position, to avoid the valve, elbow and piping and equipment installation thermocouple near the corner.
