The relationship between compressors and water
Thread Content
If the process gas contains water, what harm can it cause to the compressor?
Liquid slugging can occur easily, causing damage to both centrifugal compressors and reciprocating compressors. Compressors are used to transport gases, and the presence of liquid within them reduces their operational lifespan and can even lead to equipment failures
It causes water hammer. It is best to install a backflow preventer or water seal at the compressor inlet and outlet. Be sure to drain the waste before driving
Large volumes can lead to liquid slugging; therefore, a pre-compressor liquid separation tank is usually installed to protect the unit. If the liquid content in the gas medium being transported is less than 10 PPm, it has little impact on the unit.
Liquid slugging is likely to occur; compressors are used for transporting gases, while pumps are used for transporting liquids

There is liquid slugging; it is advisable to install a separator before the fluid enters the compressor
Water hammer can, even in mild cases, cause damage to the impeller; generally, its level should not exceed around 10 ppm
1. Moisture in the process gas narrows the compressed gas path, increasing resistance； 2. Affects the volumetric efficiency of gases. 3. Hinders compression, subjecting compression equipment to hydraulic shocks ； 4. If corrosive gases are present in the process gas, they can dissolve in water and cause corrosion of equipment pipes. 5. Water entering the lubrication system reduces its effectiveness, leading to increased wear on mechanical components. 6. This results in inaccurate calculations of gas flow rates.
1 The compressor efficiency declines, resulting in increased energy consumption； 2 pairs cause corrosion to the components in contact with gas ； 3. A lower value can cause shock to the intake and exhaust valves, leading to valve failures or damage; in severe cases, it can result in water hammer in the compressor, causing damage to the compressor ；
Hehe, liquid slugging can easily occur, and it causes significant damage to the blades. Not to mention compressors, even in steam turbines the conductivity of the steam needs to be controlled – just think about what would happen if water got into a compressor! ! !
