Why does a water ring vacuum pump lose its vacuum? Which teacher can give a detailed explanation?
If the vacuum is not maintained, the equipment vibrates violently and noise levels increase; prolonged operation can lead to damage to the water ring vacuum pump
Why is there such severe vibration?
Prevent water from flowing back into the system! The check valve is not reliable
By disrupting the vacuum effect, it can be used to control the flow of various types of fluids, including air, water, steam, various corrosive substances, mud, oils, liquid metals, and radioactive materials. To prevent pipes and other equipment from becoming dented or cracked, thereby ensuring the safety of the equipment. —— Excerpted from Encyclopedia
After the vacuum pump is shut down, the vacuum break valve must be opened to prevent water (water ring) or oil from flowing back into the pump’s inlet pipeline~~
Why not use the method of closing the inlet valve? It is mainly to prevent excessive vacuum, which could cause vibrations due to large-scale vaporization of water.
