      The causes of uneven heating tube heating

       Uneven 1 resistance wire material hardness

      Because of the uneven resistance wire material hardness, produce electric wire wound into ahelical pitch stretching after the uneven. This situation generally occurs process using well typereturns in the electric wire drawing in. The winding spiral electric heating wires, the unevenuneven tension can also influence between spiral spacing.

      Heating wire 2 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, inplus powder will be generated when the sagging phenomenon, which is the heating wire coil pitch is under dense dilute.

      3 process operation is not appropriate

      The rods are exposed does not meet the requirements of lead in plus powder, short edge sidewhen vibration powder adding side knock edge electric wire tube will lead out rod stretched too long, or when the edge vibration boundary plus powder side knock edge pressure lead out rodtube. 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 electricalwire distribution uniformity.

      4 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.
