Ningbo pipeline soda mixed heater

QSH soft drinks mixed heater mixer pipeline soda soda mixed sense a sense, the steam mixed with water, the heat transfer surface contact, contact with surface water and instant vaporization expansion, namely partial explosion, always noise. Such as drops of water falling into the boiling pan, it will produce an explosion scattered, it is the same reason. 2, the steam mixed with water, the bigger the better heat transfer surface requirements (greater heat transfer surface, the explosive power per unit area is smaller, the smaller the noise), such as sand thrown into the water. 3, the steam mixed with water, the lower the better static requirements (flow faster dynamic pressure is higher, the low static pressure, buffer the better, the smaller the noise), such as a fist and hit the batting. Pipeline construction 1 soda mixed heater, ducted soda mixed heater consists of a core tube (de Laval nozzle) and the shell composition, the core wall has a lot slant-hole, core tube inlet end of a relatively small portion of the throat, middle part of the core tube are mixed and heated area, steam zone between the core tube and housing. 2, pipeline soda mixed heater operation, high velocity jet of cold water from the throat into the heating zone, while the steam from the high-speed core tube inclined holes injected into the heating zone, soft drinks mixed heat, hot water production. 3, pipeline soda mixed heater, seemingly simple structure, do not really simple. Such as automobile tires, the tires are not the same. 4, pipeline soda mixed heater, there are stringent technical requirements in production, which is the core technology of the product. 5, pipeline soda mixed heater core component of the core tube, its streamlined shape, throat diameter, number of holes slant, slant-hole angle is critical to the combined effects of noise, vibration, pressure loss results. 6, pipeline soda mixed heater core pipe, not all of the core tube can be called de Laval nozzle, but not all plants can produce a de Laval nozzle. 7, the standard de Laval nozzle, and Minglawaer nozzle, Laval nozzle, Swedes Laval invention, rocket engines and aero-engine most commonly used components. Noise and vibration pipeline soda mixed heater 1, pipeline soda mixed heater normal operating pressure, vapor zone pressure is greater than the heating zone pressure 0.05MPa. 2, pipeline soda mixed heater, during normal operation, the steam mixed with water at a high speed and large heat exchange area status, no noise, no vibration, and only the slightest sound of steam flow (use upstairs and downstairs had no effect ). 3, in addition to non-formal factory product generates noise and vibration, the improper use of heaters, also produce noise and vibration. 4, if the vapor zone pressure below the pressure heating zone, the steam can not enter the water heater does not operate. 5, if the heater heating the vapor zone and zone pressure difference is too small, not high velocity jet of steam into the heating zone, but similar to the bubbles into the heating zone, heat and water vapor contacting a small area, would generate noise. 6, if the steam pressure is unstable, the heater did not work properly. When the vapor zone pressure is less than the heating zone pressure, the water is returned to the steam zone, momentary pressure drop piping system; when the vapor zone pressure is greater than the heating zone pressure, steam flow squeeze back toward the heating zone, the pipeline system pressure rise instantly. So again, have an impact on the piping system, and produce vibrations that we often say that water hammer. 7, if the water is returned to the steam area, steam and water, a smaller area of ??the contact heat transfer, and generate more noise, even the terrible explosion sound. 8, if the steam pipe is not smooth, or the steam pipe is too small, the heater is far less than the vapor zone pressure, static pressure steam. If the vapor zone pressure is less than the heating zone pressure, the water is returned to the steam zone; if the water is returned to the steam area, clogging the steam inclined hole, steam zone force equal to the static pressure steam, steam flow squeeze back toward the heating zone. Thus, similar to the vapor pressure is unstable, and the noise and vibration.
