Armored thermocouple has many advantages such as tortuous, high pressure resistance, fast thermal response time and strong durability. It is the same as industrial assembled thermocouple, as a sensor for measuring temperature, and generally used as a supporting application of appearance, recording appearance and electronic regulator. It can also be used as a temperature sensing element of assembled thermocouple. The following xiaobian to tell you about armoured thermocouple in the device, maintenance of 12 matters, in the use of the need to remember.
1, armored thermocouple is necessary to Pierce into place, stop screw tight in place;
2, armoured thermocouple extraction advocate the use of small slot box;
3, armored thermocouple fixing is necessary to use stainless steel wire instead;
4. It is necessary to wrap the interface between armored thermocouple and furnace wall, and then lead it into the maintenance pipe of keji;
5, in order to prevent boiler settlement, advocate the use of transition junction box, and then connected to the preheater with compensation wire;
6, the furnace wall and the preheater bridge or maintenance tube should not be closed, to guard against high warm current directly into the preheater and damage the components inside (Tianjin Power construction because of no attention, caused the damage of the preheater);
7, the position of the preheater device can not be too far, or the length of the thermocouple is not enough;
8. Wiring should be correct and firm.
9. It is necessary to pass verification before armoured thermocouple device;
10. The height of the block pressing device is necessary to be consistent, generally 150~200mm above the level;
11, pressing block welding requirements with three side spot welding, hot couple insert do not spot welding, side spot welding should pay attention to do not stop screws to weld dead;
12, pipe wall temperature should be symmetrical device up and down;
