1. Overview of the single-head heating tube with conventional structure and external wiring. The so-called single-head heating tube with conventional structure and external wiring refers to its simple appearance and structure, without accessories such as threads, limiters, protective sleeves, etc. This type of heating tube is commonly used in the structural technology of outer wire winding and single-ended lead wire. It can generally be used for heating molds, packaging machinery, sealing machinery, etc.
2. Performance characteristics of conventional structure external lead single-head heating tube
. High efficiency, high-precision product with in-depth research to transmit heat without loss
. Long life, using high nickel alloy heating element, with durability High temperature and oxidation resistance, and the use of heat-resistant and high-temperature insulating magnesium oxide makes it obviously have a longer life than traditional products
. The robustness adopts a structural design that can withstand mechanical vibration and impact during use, and is fixed at the same time The baffle structure is easy to fix and use the heating tube
. The electrical performance has excellent insulation performance, especially in the cold state, it can maintain good insulation performance
. Operability even if multiple simultaneous heaters are used , will not interfere with each other, and wiring is easy to complete in the box
. There are various types, models, and shapes. There are metric and imperial sizes, regular and non-standard types, and they can also be customized according to customer requirements.
3. Precautions for the use of single-head heating tubes with conventional structure external wiring. The manufacturing process and material selection of the heating tube are important, but they also need to be applied correctly, otherwise it will also affect the service life of the electric heating tube, so understand how to correctly It is also very important to use heating rods. The following will introduce the commonly used points
. The cartridge type electric heating tube itself has a high watt density. Often due to poor heat transfer, the outer tube body will be charred and the internal high temperature will accelerate the electric heating. The hot wire is aging, causing the heating wire to break.
. Pay attention to precision when processing deep holes in the mold. Do not drill holes at both ends, because the junction cannot be tightly sealed and there will be large pores, which will cause poor heat dissipation of the electric 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 must not be exposed to pollutants and moisture in the place of use to prevent leakage. It is best to reserve it outside the mold.
. When using an electric heating tube when starting up, it is best to preheat it for a few minutes 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.
