, , : ) Three working principles
: There are several groups of small holes with matching diameters distributed on the cavity wall of the rotary steam muffler heater. When the steam is ejected outward at high speed from the oblique small holes, the cold water It is ejected from another small hole in each set, and the two quickly exchange heat. Since the steam in the heater is rotated and ejected along the tangential direction, this greatly reduces the impact of the steam on the heated liquid. The impact angle effectively reduces the noise caused by the impact vibration of steam on liquid. On the other hand, the steam rotates and sprays out in the tangential direction
, causing the heated liquid to rotate in the same direction, and the hot and cold convection becomes more frequent. This process suppresses the noise generated by the steam bubbles to a minimum, and the entire The liquid in the container is quickly heated during the rotational motion.
: )Four working characteristics
: Calculation formula of working characteristics:
: < r/ : br />
: Among them, heating time (minutes) and heating water weight< /Steam consumption per unit time (/)
: Specific heat capacity of water (/℃).
: Application examples:
: When the steam working pressure (gauge pressure) is used, select a specified heater to heat tons of water from ℃ to ℃. How long does it take?
: When looking up the table, the heater steam consumption/, heat enthalpy/.
: So:

: )Five selection instructions
: Design selection: The working characteristics formula can be transformed into:
:
< r/ : br />
:
: Calculate the required steam consumption based on the known value. : Renovation and selection: According to the size of the original steam pipe, select a heater of the same specification.
: Design selection example:
: There is a bathroom hot water tank with tons of water. When the steam working pressure (gauge pressure) is used, the water in the water tank is required to be heated from ℃ to ℃ within minutes. Ask about the specifications and quantity of heaters that need to be selected?

: ) Six installation and debugging
: When this product is used, it must be immersed at least under the water surface and no closer than the side wall and bottom of the container. It is best to place it at the geometric center of the container.
: When selecting, the diameter of the pipe should be greater than or equal to the nominal diameter of the heater. When multiple heaters are used in parallel, the cross-sectional area of the steam pipe should be greater than or equal to the sum of the cross-sectional areas of all heater connecting pipes. .
: When the steam pressure is greater than (gauge pressure), a steam pressure reducing valve should be installed to reduce the pressure, and a filter should be installed in front of it.
: A check valve must be installed on the steam pipeline near the heater to prevent siphoning when the steam is stopped, resulting in water backflow.
: The steam pipe near the heater should be firmly fixed so that it will not swing when working.
: Multiple heaters are used in parallel and should be evenly distributed. Because of their heavy weight, they should be supported. The installation positioning depends on the site conditions.
: The water temperature and water level in the water tank should be measured and controlled using a temperature controller and a water level controller.
: If the heating speed of the heater slows down during use, it may be that the internal steam holes are blocked. The heater should be removed to clean out the impurities blocking the steam holes, and the dirt should be discharged from the drain outlet. It's best to clean it once a month.
