Cement plant special wear-resistant thermocouple is introduced

Abstract: cement plant special wear-resistant thermocouple for cement dryprocess winding kiln production line with the relevant tertiary cylinder, four cylinder, five cylinder cone temperature, central, preheater decomposing furnace temperature characteristics of smoke, the temperature of the kiln head cover, problems arising from ordinary wear resistance thermocouple protection tube material, can meet the special high temperature resistant, resistant to erosion temperature conditions, leading to shorter service life of thermocouple, conditions, product value for frequent replacement and transmission signal is not guaranteed, instrument in the alert status for a long time, at the same time adds a lot to instrument maintenance workload, this phenomenon is the universality of the existing problems in the cement industry of China.

product number: 11238191016 product name: cement plant special wear-resistant thermocouple specifications: ￠remark: 25 * 1000 * 300 mm product users have special requirements, can be in the order indicated in the contract. Product categories: wear-resistant thermocouple

product description

a, the characteristics and use the

for many years, Shanghai automation instrumentation co. , LTD. , for high temperature resistant, resistant to scour the thermowell material have done many research and study, combining with the characteristics of cement production technology abroad, after many experiments and online to confirm the NM recrystallization thermocouple has long service life, catastrophe performance is good, high heat transfer coefficient, oxidation, thermal shock resistance, high temperature resistant, corrosion resistance, resistance to erosion, nodules, slagging, installation convenient use, can be used to measure 600 ~ 1200 ℃, special temperature measuring occasion, is now in our country of corundum, alumina, the material such as graphite, oxide, silicon carbide thermocouple protection tube is unable to substitute. NM alloy steel thermocouple protection tube, not only solved the Chinese cement industry a great problem for the wear resistant temperature control, but also for each unit using has brought considerable economic benefits.

2, product specifications professional design, professional development of the temperature measuring instrument. High precision, long service life. The convulsions of good performance, high heat transfer coefficient. Oxidation resistance, corrosion resistance. Thermal shock, high temperature resistant. Nodules, slagging. 4 ~ 8 mm wall thickness. Rapid response function, strong stability. Any alternative protection tube length. Can be used without preheating. Many kinds of installation method suitable for individual users. Optional on the display. The optional built-in transmitter. The anti-interference ability in the process of long distance transmission. Using the environment temperature range wide, work stable and reliable.

3, main technical index

1, the brief description as the quality of cement special thermocouple temperature sensor, and DCS, PLC, usually display meter, recording meter and electronic regulator. It can directly measure triple tube three times, four bottles, five buckets, duct, decomposition furnace, preheater smoke chamber, kiln hood, 600 ~ 1320 ℃ within the scope of the gas temperature and media. 2, a temperature measurement range and the permissible error

4, use the

NM series alloy wear-resistant thermocouple is mainly composed of junction box, connection pipe, special protection tube, insulating lining, terminal blocks, special casing pipe, hot electrode formed the basic structure, and is equipped with a variety of installed components, at the same time in the options in the optional integrated temperature transmitter. NM series alloy steel thermocouple protection tube general wall thickness of 4 ~ 8 mm ( According to measuring temperature place) 。 The protection tube is designed for cement plant, its role is to extend the C3, C4 and C5, preheater, decomposition furnace, tertiary duct smoke, kiln hood of the service life of thermocouple temperature measuring point. When installing the product, can according to different various industrial measurement and control points, the advance in the kiln tube blank or protection, and select the corresponding specifications of special thermocouple. In the product design process, we have full consideration to the running of 1000 ~ 10000 t/D cement production line installation specifications and models, for the use of your every measurement point on the production line. Protecting tube length choice: inserting depth in furnace + + part exposed outside the furnace wall thickness = length in the process of production, installation or replace thermocouple, please place the thermocouple slowly into the furnace and the fixed connection device. In process measurement and control point temperature measurement for a long time at 1100 ℃, the normal work of the K type thermocouple has about 60 working days or so, because I silk is in a state of high temperature for a long time, its precision will produce tiny change, can change to the requirements of the process of thermocouple temperature measurement components. Involves the blanking or flushing is used in the thermocouple 60 working days, will be 90 ℃ thermocouple flip reinstall, prolongs the life that special wear-resistant thermocouple.
