The reasons for the uneven heating of the W Type Tubular Heating Element, the W Type Tubular Heating Element and the stainless steel heating tube are as follows:
1. 220V U Shaped Tubular Heating Element resistance wire material hardness is uneven
Due to the uneven hardness of the material of the electric resistance wire, the unevenness of the spiral pitch after the electric heating wire is wound is generated. This situation generally occurs when the drawn electric heating wire is in a well-returned process. When the spiral heating wire is wound, the uneven tension can also affect the unevenness between the spiral pitches.
2. The design of the 220V U Shaped Tubular Heating Element resistance wire is improper
Generally, the heating wire in the 220V 380V Circle Type Tubular Heating Element is designed to be spiral, that is, spring-like. If the ratio of the diameter D of the wire core rod to the diameter d of the heating wire is D/d>8, the drooping phenomenon will occur when the powder is added, which is the upper and lower density of the heating wire ring.
3. 220V 380V Circle Type Tubular Heating Element process operation is not appropriate
When the powder is added, the exposed rod is not in conformity with the requirement. When the powder is too short, the powder is pulled and the tube is pulled while the powder is being twisted. When the rod is too long, the rod is pressed and the rod is pressed while the powder is vibrated. In doing so, the heating wire is partially too thin or partially too dense or even the electric heating wire and the coil are short-circuited. Improper operation of the shrink tube process also affects the uniformity of the distribution of the heating wire.
4. Electric Dryer Tubular Heating Element powdering equipment is defective
For example, the amplitude of the adding device is unstable, the lifting speed of the guide bar is not uniform, and the speed of the powder leakage is fast and slow. Even if the various parameters are normal, the magnesium oxide powder is too dense.
With the increasing number of heating pipes and electric Oven Coil Electric Tubular Heating Element enterprises, the competition of domestic heating pipe enterprises is also constantly upgrading. Nowadays, the scope of heating pipe enterprises must include market research, product development or improvement, manufacturing, sales, After-sales service until the whole process of recycling, involving the entire life cycle of the heat pipe products, always pay attention to the concept of serving customers all the way, all-round. Under the same product quality conditions, who can do more in the after-sales service, to a certain extent, determines who can win more market share. At the same time, whether it is to improve quality, increase prices, or adopt trade protection measures, take a diversified route, and increase the value-added road, all aim to enhance their influence and status in the heat pipe market.
