At present, most of the heating still uses steam. Steam is used as a heat source for different pressure levels in various processes of vulcanization, and is the main medium for rubber vulcanizer/heating. Providing sufficient heat in the vulcanization process in a timely and accurate manner is a necessary condition for ensuring the quality of vulcanization. Let us introduce the benefits of low pressure use of the vulcanizer steam line. After the high pressure steam is depressurized, part of the condensed water evaporates, the dryness of the steam increases, and the steam quality increases. The latent heat of steam at low pressure is greater and the heat transfer effect is better. The heat of the condensed water produced by the steam after the low-pressure use is reduced, and the energy waste after the discharge is small. Low pressure steam is safer. The pressure can be used to control the temperature by depressurization. At present, most tire companies choose “low pressure use” for low pressure steam supply selection, but low pressure use requires high piping design and construction. At the same time, because the vulcanizer is also shaped with low pressure steam, low pressure steam directly enters the capsule, so the steam quality The requirements are high, and there are mainly the following problems in low-voltage use. The steam regulating valve is unstable in operation and has a low service life. The steam pressure is unstable, which is likely to cause batch temperature drop and pressure drop. The steam condensate is not discharged in time, and the temperature of the hot plate fluctuates greatly.
