There are two reasons for the noise produced by heating hot water with steam. First, due to the high pressure of the steam, the liquid vibrates vertically and violently after being ejected to produce medium-frequency noise. Second, due to the temperature difference between steam and liquid, the mixture of steam and low-temperature water shrinks rapidly, resulting in low-frequency noise. The DXX type steam silencing heater officially starts from eliminating the source of the noise. First, the DXX type steam silencing heating There are several groups of oblique small holes distributed on the nozzle of the nozzle, from which the steam is ejected obliquely, which is tangential to the rotating fluid in the cavity. This greatly avoids the medium frequency noise caused by vertical impact. In addition, the liquid around the nozzle is absorbed by the outer casing and the large container. Other low-temperature liquids are isolated, so that the steam is first mixed with high-temperature water, so the low-frequency noise generated due to the temperature difference is greatly weakened. However, what should be noted here is that when the pressure of the steam is greater than 3kg/cm2, Be sure to install a pressure reducing valve to reduce the pressure to less than 3kg/cm2.
