Feel free to ask questions regarding water ring vacuum pumps
Thread Content
I work for a manufacturer of water ring vacuum pumps, a well-known large enterprise in China. To avoid being accused of advertising, I won’t mention the company’s name. If you have any questions or need information regarding water ring vacuum pumps, feel free to ask below. I will definitely help you respond as soon as I have time. Thank you all.
For water ring pump operation, it seems that the temperature of the working water should be as low as possible. However, if the temperature is too low, I feel that the pumping efficiency decreases. Please advise
Lower water temperature certainly has a better effect on the vacuum pump.
What factors affect the gas handling capacity of a water ring vacuum pump? Import vacuum level? Intake air temperature? Working fluid temperature?
I used one before, a water-ring vacuum pump for vacuum belt dryers; after half a year of use, there was a constant problem of insufficient vacuum level, and I’m not sure what the reason is
The vacuum pump is part of the complete set provided by the manufacturer; it’s from Yantai… and I guess it’s one of the most well-known manufacturers of vacuum belt dryers in the country
Hello, I’m from the chlor-alkali section. Last time I asked about the insufficient suction power of the hydrogen compressor, you said that the possibility of corrosion of the impeller (cavitation) was very low. According to the manufacturer (who didn’t see the condition of the impeller firsthand), it was cavitation. What do you think is going on? The temperature is usually kept below 45°C.
In the case of hydrogen compressors, a control temperature of 45°C is a bit high; using water at 5°C or 7°C for control will lower the temperature, and this should increase the rate of extraction.
Why does the pumping capacity of a water ring vacuum pump decrease after it has been operating for some time? The impellers have been checked and are in good condition; the temperature of the working fluid is high, but the plate heat exchanger (used for heating/cooling the working fluid) is functioning properly. Please ask the manufacturer to help answer
The effect of separating gas from liquid is not significant. As I understand it, the liquid should be retained while the gas is removed; the liquid level in the gas-liquid separator should rise to a certain level before it can be discharged. However, in our case, the liquid level always drops to a certain level and then fills up again on its own. We are pressurizing acetylene gas; there is sediment inside the separator. According to the principle of water ring pumps, when there is too much sediment, less water is available, and the liquid level remains constant. I’ve mentioned everything that comes to mind; I hope fellow users can point out any mistakes. Thank you very much
