Heating rod with thermocouple
Single -ended electric heating pipes, also known as straight single -header heating pipes. The use of single -ended electric heating pipes is to punch holes on the mold, embed the single -ended electric heating pipe in the moldhole, and then connect to the power heating element that heats up the power and heat it to the mold.
I.Introduction to heating rods with thermocouple
The heating rod with temperature measurement is an electric heating tube that adds a thermocouple to the inside of the heating tube, which can detect the internal temperature of the electric heating tube and combine the temperature control instrument to achieve the purpose of temperature control. Heating rods with temperature measurement are normally equipped with type K or type J thermocouples. Temperature measurement points can be placed in the middle and bottom.
II.Heating rods with temperature measurement are mainly used in:
Bag making machine, edge banding machine, packaging machine, 3D printer, mold heating, sealing machine, etc
III.Main technical parameters of heating tubes
1. Shell material: 321 imported from Germany, stainless steel 310S material, preferably Ingrid material, high temperature resistance.
2. Heating wire material: 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, Cr20Ni80, etc
3. Insulating filler: medium temperature insulating magnesium oxide powder, high temperature insulating magnesium oxide powder, etc
4. High temperature lead: mainly porcelain bead lead.
5. Rated voltage: 110V, 220V, 380V, etc
6. Power (surface load): power is determined according to surface load and size, the general surface load is: domestic process: 5W/cm2; Imported process grade A: 5W-12W/cm2; Imported process AA grade: 12W-15W/cm2; Imported process AAA grade: 15W-20W/cm2;
7. Pipe diameter: 12mm-30mm
8. Length: according to customer requirements
9. Cold insulation resistance: the cold insulation resistance should not be less than 50MΩ during factory inspection; After the sealing test, the insulation resistance after long-term storage or use should not be less than 1MΩ
10. Cold leakage current: ≤ 0.5 mA
11. Cold insulation: 1600V. 1/seg
12. Thermocouple type: J type (measurement range within 600 degrees), K type (measurement range within 450 degrees)
13. Is the thermocouple at the bottom or in the middle
VI.Single -ended electric heating pipe for hot bending machine advantage
1.Non -customized, flexible production, and meet the heating requirements of various equipment.
2.The working temperature can be as high as 760 ° C (imported AAA -level micro -heating pipe)
3.The surface load can be as high as 20-25W/cm2
4.The minimum pipe diameter can be done 3mm
5.K-type or J-type thermocouples can be used to detect temperature
6.It can flexibly add fixing flanges, threads, etc. for fixing
V.Installation diagram or precautions of low-voltage 24V single-head electric heating pipe
For single -ended electric heating pipes, the most important thing is to ensure that the calories of the single -ended electric heating pipe can be passed to the heating medium in time, reducing the temperature of the internal material of the single -ended electric heating pipe. This can effectively increase the single -ended heating tube service life.We should pay attention to the following points during use:
1.Try to reduce the gap between the outer diameter of the single -ended electric heating pipe and the pores of the pores. Usually the gap between the two is less than 0.2mm
2.The installation hole should be able to fit the single -ended electric heating pipe. The deviation tolerance should be controlled within 0.05mm.If you deviate too much, you need to modify the processing hole
3.Before installation of the single -ended electric heating pipe, the impurities left in the holes of the mold should be cleaned. If the residues such as organic oil are left, it will be carbonized after heating, which will affect the ability of thermal conduction.
VI.Description of the wiring method of Single-head heating tube
A pipe connected to the power supply: directly according to the voltage size to wire, usually 220V, a live wire, a zero wire; 380V, if there are only 2 terminal posts, then it is enough to connect 2 live wires.
Multiple pipes connected to the power supply: can be taken according to the actual situation: parallel, series, delta connection or Y-type connection, etc. If you don’t understand the details, you can consult our sales customer service.
