The reason of non-uniform heat of the electric heating tube

 The reasons | heating pipe | stainless steel heating uneven heating pipe of the electric heating tube of the following points:

1 electric heating tube resistance wire material hardness

Because of the uneven resistance wire material hardness, produce electric wirewound into a helical pitch stretching after the uneven. This situation generally occurs process using well type returns in the electric wire drawing in. The windingspiral electric heating wires, the uneven uneven tension can also influence between spiral spacing.

2 electric heating tube resistance wire improper design

General electric heating wire in the tube are designed into a spiral spring shape,i.e.. If the wire around the core rod diameter of D and the electric heating wire diameter ratio of D is D/d > 8, in plus powder will be generated when the sagging phenomenon, which is the heating wire coil pitch is under dense dilute.

3 electric heating tube process operation is not appropriate

The rods are exposed does not meet the requirements of lead in plus powder,short edge side when vibration powder adding side knock edge will lead out rodtube electric heating wire is elongated, or too long when the boundary vibration boundary plus powder side knock edge pressure lead out rod tube. Do cause the heating wire is too thin or too dense local local even heating wire circle and circle short circuit. Tube reducing process of improper operation will also affect the electrical wire distribution uniformity.

4 electric heating tube plus powder equipment faults

For example, plus equipment amplitude instability, the guide rod lifting speed is not uniform, the powder leakage speed slow and so on. Even if all parameters are normal, magnesium oxide powder is under dense dilute.

The above reasons basic will cause the electric heating tube | stainless steel heating tube heating uneven | heating tube.
