Disadvantages of water flush pumps
Thread Content
At present, water flush pumps are slowly being eliminated. What are their main disadvantages? This post was last edited by lxzzl on 2009-3-9 08:41 ]
The main disadvantage is the large amount of wastewater discharge and the high installation height requirements!
The water flushing pump is to inject the water in the pool into the variable diameter nozzle at high speed through the water pump and suck the gas to generate a vacuum. Its advantages are: ① Simple structure, low equipment cost, convenient operation and maintenance; ② As long as the materials are suitable, corrosive situations can be easily solved. Its disadvantages are: ① Due to the limitation of the vapor pressure of the water itself, the ultimate vacuum degree is not high; ② The ultimate vacuum degree is related to the water temperature. In order to maintain the vacuum degree, new water needs to be continuously added to cool the circulating water of the pool. With the application and development of chemical equipment technology, the pool also needs to have a certain volume and occupy a large area. ; ⑧ Water may be poured back into the vacuum system; ④ In the pool, the organic matter suctioned in by the vacuum floats on the surface of the pool, so the overflow water should be treated as waste water. The amount of waste water is large, and the volatile tail gas evaporates from the water, causing serious waste gas pollution; ⑤ A lot of noise is generated when the water flow impacts.

The key is that it consumes a lot of energy, and each of the others has its own strengths and weaknesses. In addition, with the continuous emergence of corrosion-resistant and explosion-proof vacuum pumps, water jet pumps are gradually fading out.
You are quite a layman. Is there any vacuum pump that can directly pump pollution, corrosive gases, dust, and liquids into itself? No condensation and filtration equipment is required. There is no universal material or universal technology, only the right one is good.
Water ring pumps often need to prevent pollution； When selecting equipment, water flushing pumps are often chosen because of volatile, corrosive and other reasons. Water flush pumps have many disadvantages, but when the actual conditions of the factory are limited, water flush pumps are sometimes the best choice.
