The electric heating tube of flat vulcanizing machine is a kind of electric heating element specially designed for electric flat plate vulcanizing machine. Plate vulcanizing machine is main equipment of vulcanized rubber products, the hot plate surface temperature difference is the main performance index to measure the vulcanizing machine, mainly caused by the temperature difference between the hot plate surface of the larger is two: 1, the environment temperature effect; 2, the electric heating tube spacing layout design, therefore, the key to solve the problem of temperature difference between the surface of the hot plate vulcanizing machine electric is the minimum temperature difference and electric heating tube arranged in spaced relationship.
Flat vulcanizing machine is mainly used for the electric heating tube heating using template vulcanizing machine, stainless steel tube production, divided into single head, double stainless steel tube, and is the product in the working state, the tube surface temperature is very high, and the thermal insulation and leakage current, high temperature internal design using magnesium oxide and oxidation heating selection of high temperature resistant, stainless steel tube, fully consider the installation and use of the environment, and require the use of special treatment on the sealing element, in order to meet the customer's equipment safety and service life of the heating element demand. The technical parameters of the electric heating tube type sulfide are: sulfide type heat pipe single hair working voltage was 220 (V) or 380 (V), using the power of template based temperature, diameter of common 14mm, 16mm and 18mm, the material can be used in SUS304 seamless tube, use condition of sulfide as template heating. The surface polishing, blackening, sealing glass, sealing glue, epoxy resin, electrical performance for the long-term placement of insulation value greater than 50M, the leakage current is less than 0.5mA.
The main technical requirements of vulcanizing machine: use temperature is usually 180-200 ~ C, the surface load of the conventional electric heating tube to 3-7W/ cm, ensure uniform surface temperature of template plate vulcanizing machine, reasonable arrangement of the template hole distance, the temperature difference between the hot plate surface to a minimum, considering the electric heating pipe installation is convenient, general the star connection.
