Why does water hammer always occur when steam condensate at 4.0 and 1.0 comes into contact? How to handle it
Water hammer occurs only when there is condensate; steam at low pressure should be drained at least before each cycle.
4.0 The condensate flows into 1.0 condensate; as the pressure of the 4.0 steam condensate decreases, some steam is generated, which leads to water hammer
What is the condensate temperature at 4.0, and what is it at 1.0? If they are combined directly, water hammer will definitely occur~
The liquefaction caused by pressure drop leads to the water machine phenomenon.
It is normal for water hammer to occur in the factory’s steam pipes during startup, as water condenses when the pipes are cold. However, it is abnormal if water hammer still occurs after the system has been running for some time after starting the vehicle. Strainers cannot solve the problem of water hammer, as the condensate return pipes always exist. The solution is to maintain a certain degree of superheat in the steam, typically 5 to 10 degrees, which needs to be determined based on the pipeline transmission distance and heat loss. The second is to improve pipeline insulation in order to minimize heat loss. Use as few steam traps as possible, as their steam loss is too high.
Why merge these two streams of steam with different specifications? When low-pressure air enters, it lowers the temperature of high-pressure air, which results in the formation of condensate!
Just discharge them separately. . . It’s the same principle as steam impact due to condensate; 4 units represent steam, while 1 unit represents condensate
The principle of vacuum flash evaporation generates vapor, resulting in a vapor-liquid mixed-flow water hammer.
The pressure is different, the temperature is different; pressure changes result in condensation
Solution: Increasing the flash tank for high-pressure condensate can solve the problem. There is another device that can also resolve it; I’ve forgotten its exact name
