Introduction to cartridge heater with thermocouple
Cartridge heater with thermocouple adds thermocouple thermocouples inside the cartridge heater.The thermocouple can detect the internal temperature of the electricheating pipe and realize the purpose of temperature control by combiningwith the temperature control instrument. Cartridge heater with thermocouple is internally equipped with a K or J thermocouple.
Cartridge heater with thermocouple application scenario
Cartridge heater with thermocouple is mainly applied to：
Bag making machine, edge sealing machine, packing machine, 3D printer, mold heating, sealing machine, etc.
Cartridge heater with thermocouple main technical parameters
1. shell material: stainless steel 304, stainless steel 321, stainless steel 310S, Ying Lai 800, Ying Lai 840.
2. material of electric heating wire: 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, Cr20Ni80, etc.
3. insulation filler: medium temperature insulating magnesia powder, high temperature insulating magnesia powder, etc.
4.High temperature lead: silica gel high temperature lead, mica hightemperature lead, silica gel glass fiber tin-plated copper wire, micaglass fiber pure nickel wire, etc.
5. rated voltage: 12V, 24V, 36V, 48V, 110V, 220V, 380V, etc.
6.Power (surface load): Power is determined by surface load and size. Thegeneral surface load is: domestic process: 5W / cm2; imported processA: 5W - 12W / cm2; imported process AA: 12W - 15W / cm2; importedprocess AAA: 15W - 20W / cm2;
7. diameter: 3mm-30mm
8. length: according to your request.
9. type of thermocouple: type J (within 600 degrees of measurement) and type K (within 450 degrees of measurement).
10. is the thermocouple at the bottom or in the middle.
Cartridge heater with thermocouple installation matters needing attention
Forthe cartridge heater, the most important thing is to ensure that theheat of the cartridge heater with thermocouple can be transferred to theheating medium in time, reducing the temperature of the internalmaterial of the electric cartridge heater, which can effectively improvethe service life of the cartridge heater with thermocouple. In the course of using, we should pay attention to the following points:
1.The gap between the outer diameter of cartridge heater and itsinsertion aperture should be reduced as far as possible. Usually the gapbetween them is less than 0.2 mm.
2.The mounting hole should be able to fit with cartridge heater andthermocouple. The deviation tolerance should be controlled within 0.05mm. If the deviation is too large, the machining hole should becorrected.
3.Carridge heater with thermocouple should be cleaned before installationof mold holes left impurities, such as residual organic oil, will becarbonized after heating, thereby affecting the ability of heatconduction.
4.If the length of the cartridge heater with thermocouple exceeds 300 mm,the problem of banana bending should be considered, and the distancebetween the tube and the die hole should be increased accordingly.
Cartridge heater with thermocouple connection mode description
Asingle cartridge heater is connected directly to the power supply:usually 220V, a hot wire, a zero wire; 380V, if there are only twoterminals, then two hot wires can be connected.
Multiplecartridge heaters can be connected according to the actual situation:parallel, series, triangular connection or Y-type connection. Those who do not understand can consult us.
Compared with the ordinary cartridge heater, the port does not use terminal connection, so that it has a high temperature resistance and strong mechanical performance, is suitable for embedded mold heating, vibration larger occasions.
