Cast Iron Thick Film Heater Note
Cast iron Thick Film Heater Note
1, the working voltage shall not exceed 10% of the rated value; air relative humidity of not more than 95%, no explosive and corrosive gases.
2, the wiring part of the heating layer, the insulation layer, the shell should be effectively ground; to avoid contact with corrosive, explosive media, moisture; lead wire should be able to withstand long-term wiring part of the temperature and heating load, Avoid excessive force
3, metal casting heater should be placed in a dry place, if long-term placement, insulation resistance below 1MΩ, can be about 200 degrees Celsius oven baking 5-6 hours, you can return to normal. Or reduce the voltage through the heating until the insulation resistance is restored.
4, metal casting heater should be fixed positioning, effective heating area must be close with the heating body, is strictly prohibited air burning. Found that the surface of dust or contaminants, it should be promptly cleaned and re-use, so as not to affect the heat and shorten the service life.
5, the electric tube outlet side of the magnesium oxide powder, in the use of places to avoid contaminants and water infiltration, to prevent the occurrence of leakage accidents.
Cast aluminum Thick Film Heater is a tubular heating element for the heating element, with high-quality casting material for the shell by die-casting Thick Film Heater, the use of temperature is generally between 150 ~ 450 degrees Celsius, can be widely used in plastic machinery, Die, cable machinery, chemicals, rubber, oil and other equipment. Cast aluminum heater features a long life, good insulation properties, mechanical properties, corrosion resistance, anti-magnetic field and so on. Explosion-proof heater explosion-proof mark for Exd Ⅱ BT4ExD Ⅱ BT6Exde Ⅱ CT6 and so on.
Cast aluminum Thick Film Heater is a highly efficient thermal division of the heater, excellent thermal conductivity of the metal alloy to ensure that the hot surface temperature uniformity, eliminating the hot spots and cold spots. With long life, good insulation properties, mechanical properties, corrosion resistance, anti-magnetic field and so on. The external cooling surface to increase the insulation device, the heat sink sintering infrared can save 35% of electricity.
Cast aluminum Thick Film Heater is a kind of Thick Film Heater.
Thick tube heater varieties include: cast aluminum heater, cast iron heater, quartz tube heater, stainless steel electric heating tube, 10 steel heating tube, with winding heat sink heating tube, VC443, VC442, VC441, VC432 induction heater, Hot plate assembly, vacuum diffusion pump electric heating plate, dust-free heater, thermocouple, high temperature line, ceramic heating tile, resistance wire and other specifications.
Thick Film Heater manufacturer to explain it using the fault handling method:
1) use a multimeter to measure the main circuit power is normal, check the superior power supply is sent out.
2) Open the regulator module Check the module circuit board is normal, replace the regulator module and replace the fuse.
3) the use of multimeter DC voltage file relay relay whether there is a direct current, if no electricity that emergency stop closure is not closed, notify the instrument with the check.
4) When the fault alarm relay action, the fault alarm light will also have sound alarm, if the overheating temperature controller overheating alarm, should stop using Thick Film Heater to be used after the temperature drop, and further check the relevant equipment. If the regulator module internal fault alarm, generally caused by electronic components burned, should be found as soon as possible the same type of regulator module spare parts replacement to ensure that production needs. If the media temperature measurement device failure alarm, you should check the replacement of the temperature probe.
5) When the regulator module does not receive the control signal, it should use the special measuring current signal clamp meter to measure, or in the regulator module to remove any one line, the multimeter hit the current file in series with the two Line to see if there is a current signal sent over, if not, then inform the instrument staff with the check.
6) in the Thick Film Heater body will be three-phase power into the line removed, with a shaking table to measure the thickness of the Thick Film Heater insulation is normal, and a multimeter to measure the thickness of the Thick Film Heater is balanced. If the resistance is balanced then it means that there is no broken inside the Thick Film Heater.
