Regarding soda series vacuum units
Thread Content
I went to the site the day before yesterday and found a vacuum pumping unit inside the device; the equipment’s nameplate only stated: Water Vacuum Unit (more or less). This unit has a fairly large square water tank, and water is being poured into it ； At the same time, there is a structure similar to that of a steam jet pump (it looks very similar, especially the diffusion section), and there is also a pump, which is likely to be a water pump. From what I’ve read in books, as well as from my limited experience in my work, it seems that only two typical vacuum pumping devices are mentioned: steam jet pumps and liquid ring pumps. I have never seen any systems that use water for vacuum pumping (wouldn’t that require pumps that consume more water and more power?) I’ve looked up some information; it seems that this is called a soda-series vacuum unit, and it can achieve a much higher level of vacuum compared to using water jets alone. I would like to ask experienced sea users for detailed explanations regarding this device – things like its working principle, how to increase the vacuum level, and in what situations it should be used The younger sister thanks you here. :)
Common name: water rat. This steam ejector works on the same principle, but it achieves a lower vacuum level; it’s not as high as that of a steam ejector pump!
The water jet vacuum pump, formerly known as a water ejector, operates on the same principle as steam injection.
The 2nd and 3rd floors are the correct choices; the greatest advantage of this combination is its flexibility and convenience, as well as its low cost. It allows for the simultaneous extraction of water and gas. It is commonly used on construction sites to lower the level of groundwater, thereby facilitating construction work.
