Today, let's introduce the ordinary single-head mold heating tube
It is an electric heating element used for heating molds and mechanical equipment of various sizes.
Single-head heating tube, also known as single-head electric heating tube, single-end heating rod of electric heating tube, is a kind of electric heating element for heating molds and mechanical equipment of various sizes, and is also known as cartridge heater in foreign countries.
Composition of a single-head electric heating tube
Its main components are composed of: 1. stainless steel shell, 2. insulating magnesium oxide powder, 3. heating wire, 4. magnesium rod, 5. high-density insulation style, 6. lead electrode, 7. lead wire and other material original combination of single-head heating tube.
According to the diameter of the shape, the current main ones are from three millimeters to 30 millimeters, and the length is normal from ten millimeters to more than 1000 millimeters. According to the difference in its material components and the level of production technology, the quality of each one is different, mainly different from the power size, insulation withstand voltage, dimensional error and service life.
The single-head electric heating pipe is further divided into: inner lead and external wiring
Looking at the difference through the physical diagram, this is the external wiring of the single-head heating tube, which is the single-head heating tube that appears inside.
The external wiring structure is that the lead rod and lead are wired outside the heating pipe through the crimping terminal. The inner lead structure, on the other hand, is that the lead is directly in contact with the inside of the heating rod.
Do you understand the difference between the two?
The internal lead is different from the external wiring process, the production process is different, the external wiring internal resistance wire and the lead out are soldered, and then the high temperature lead is connected. The inner lead, the high-temperature lead, directly welded with the resistance wire, the high-temperature lead from the inside of the nozzle is different, the external wiring is different, because the high-temperature lead is welded with the lead rod outside, so the temperature of the welding part will not be too high at this time, and the high-temperature lead of the external wiring is generally temperature resistant to 250 degrees. Inner leads due to inside.
The high-temperature lead of the lead structure is directly welded from the inside and the resistance wire, and inside the nozzle, so the temperature resistance of the high-temperature lead of this structure should reach at least about 800 degrees, and the pure nickel wire is generally used, so the cost is also very high. The creepage phenomenon is not the same, from the perspective of the creepage phenomenon, the inner lead is safer. Production efficiency: The efficiency of the inner leads is much less than that of the outer wires. The process of internal leads is difficult when welding leads and resistance wires, so the production cycle of internal leads is generally long.
Advantages of single head heating tube:
Single-head electric heating tube is an electrical component that specializes in converting electrical energy into heat energy, thanks to its low unit price, easy to use, fast heating and no pollution, and is widely used in various heating occasions. Single head electric heating tube in high temperature seamless stainless steel uniform distribution of high temperature resistance wire, in the void part of the dense quality, filled with thermal conductivity and insulation performance of good crystalline magnesium oxide powder, this structure is not only advanced, high thermal efficiency, but also uniform heating.
When there is a current in the high-temperature resistance magnet, the heat generated diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and then is transferred to the heated part or air to achieve the purpose of heating.
