The high-density single-head electric heating tube is wired at one end of the heating tube.
When purchasing high-density single-head heating tubes, we need to pay attention to several issues:
Whether the diameter of the high-density single-head heating tube matches the diameter of the mold hole. In order to transfer the heat of the heating tube to the mold quickly, we recommend that the diameter of the heating tube be larger than the diameter of the mold hole.;
. Is there a temperature control for the high-density single-head heating tube to operate normally? If so, what is the temperature?
Whether the high-density single-head heating tube vibrates when heated.
Features of high-density single-head heating tube:
High-density single-head heating tube has a fast temperature rise and an operating temperature of &;℃. Usage: Plastic molding molds, pressure reducing assembly, cigarette making machines, quick sealing machines, pharmaceutical machinery, etc. Voltage: - Power: -/(effective heating area surface area) Recommended specifications: ︿&;︿.
Principles for selecting high-density single-head heating tubes:
Temperature resistance and corrosion resistance: For low-temperature tubes, B, aluminum tubes, and copper tubes are generally used. For high-temperature tubes, stainless steel tubes and Ingley tubes are generally used. For serious water quality In this case, Teflon electric heating tubes and stainless steel coated electric heating tubes can be used. Stainless steel coated electric heating pipes can be used under poor water quality conditions. Yinglai electric heating pipes can have good oxidation resistance and good corrosion resistance under high-temperature working conditions. Generally, Yinglai code pipes are made from domestic brands. Material substitution has the same effect.
Performance indicators of high-density single-head heating tube:
Heating time: under the test voltage, the time for the component to rise from the ambient temperature to the test temperature should not be greater than;
Rated power deviation: under the conditions of sufficient heating The deviation of the rated power of the lower components should not exceed the following specified range. For components with a rated power less than or equal to: &;%. For components with a rated power greater than +%~-% or the larger of the two;
Insulation resistance: The cold insulation resistance should not be less than &;;
High-density single head during factory inspection Precautions for the use of heating tubes:
During use of high-watt density single-head electric heating tubes, due to the rapid heating and poor heat dissipation conditions, the outer stainless steel tube body of the electric heating tube is often blackened, oxidized, and deformed, resulting in the internal heating element - electric heating alloy wire. Due to high temperature air burning, the life of the single-head electric heating tube itself is shortened. Therefore, an excellent single-head electric heating tube not only requires good production quality, but also requires mold material and processing aperture (the closer the aperture and tube diameter are, the better). A suitable aperture is not only convenient for replacement. In addition to the single-head electric heating tube, it is also conducive to the conduction of heat energy between the two, thus extending the service life of the electric heating tube itself.
When processing the deep hole of the mold, attention should be paid to the precision. Do not drill holes at both ends because the junction cannot be tightly closed and there are large pores, which will cause poor heat dissipation of the heating tube and uneven temperature of the heated body.
It should be noted that the magnesium oxide powder at the outlet end of the electric heating tube should not be exposed to pollutants and moisture in the place of use to prevent leakage. It is best to reserve it outside the mold.
. It is best to preheat the electric heating tube for several minutes when starting the machine to avoid the risk of leakage due to air humidity or water seeping into the tube. When using electric heating machinery, a grounding wire must be installed.
Design and customization of high-density single-head heating tube:
.Voltage, power.
.Pipe diameter size: can be achieved according to customer requirements.
.The length of the tube body: non-standard customization (minimum).
.The material of the electric heating tube: the main materials are carbon steel, stainless steel with coating (anti-scale treatment), (commonly known as:), titanium tube, etc.
.Selection of electric heating wire: generally iron-chromium-aluminum wire (Beijing Shougang), nickel-chromium wire (generally, resistance wire, etc.). The choice between the two depends on the customer's working environment (temperature and vibration).
.Others: working environment, terminal or lead length (regular:), whether installation threads are required (thread size), diameter and length of metal hoses, etc.
