From the pump’s performance curve, it can be seen that within a certain range, reducing the flow rate can increase the head (exit pressure); as the flow rate increases, the head decreases. I’m not sure what purpose you have in mind for increasing the water volume.
An important aspect of water ring pumps is the temperature of the gas itself and the temperature of the cooling water used in the cooler; reducing these temperatures and increasing the flow rate of the cooling water is crucial!
So far, the only situation we have encountered was a decrease in pressure due to excessively high gas temperature and high cooling water temperature, which led to a reduction in flow rate.:
Thank you all. My goal is to increase the flow rate. It’s not due to \"excessively high gas temperature and high cooling water temperature leading to reduced pressure and thus lower flow rate\"; rather, it’s about \"increasing the flow rate of the circulating water\" (note that it’s not cooling water – it’s winter now, and the temperature of the circulating water can drop below 20 degrees). How can I increase the outlet flow rate? Other factors?
It is necessary to know the following parameters in order to provide a response: inlet air temperature, water temperature, vacuum level, pump model, pump speed, motor speed, and current air volume. By how much is an increase in gas volume expected? Changing the pump speed is one of the possible methods. I specialize in research on water ring pumps, QQ14531420
The key to solving this problem is to lower the temperature of the water; if the temperature cannot be reduced, the flow rate cannot increase. The compression ratio of the pump will not rise significantly either.
There is another method: frequency conversion technology can be used to increase the pump’s speed, though not by much； Appropriately increasing the water circulation volume is also an option; similar to variable frequency technology, the increase is not significant!
A couple of days ago, while reading, I learned that closing the outlet valve and increasing the pressure can boost flow rate; it’s just theory though, as I’ve never tried it in practice. Add a water ring pump to achieve a definite increase in flow rate: lol This post was last edited by clq20040107 on 2008-1-2 at 23:40.]
A couple of days ago, while reading, I learned that closing the outlet valve and increasing the pressure can boost flow rate; it’s just theory though, as I’ve never tried it in practice. Add a water ring pump to absolutely increase the flow rate. 1. “Increasing pressure can boost the flow rate, but that’s just theory.” That’s exactly what I’m talking about, but I’m not quite sure how the traffic is changed 2. “Adding a water ring pump to increase flow rate absolutely – great idea!” It’s all over now; the boss will let you go home as well.
Changing the pump speed is one of the possible methods. I specialize in the study of water ring pumps. QQ14531420: Hello, 1. I don’t use QQ. 2. Can increasing the amount of water used change the speed of the water ring pump? Including an increase in current. 3. Increase the resistance of the export pipeline appropriately to raise the pressure; could this change the state of the water ring and increase the gas flow rate by a certain amount (e.g., 10–20%)?
May I ask the original poster: What medium is your water ring pump used to transport? What about the operating conditions?
The outlet of the water ring pump should be kept fully open. To increase its flow rate and gas delivery volume, it is not advisable to have either too much or too little circulating water; each pump has its specific requirements. The key is to ensure an adequate amount of water before starting up, so that a liquid ring can be formed at the moment of startup.
For transporting acetylene gas, the pump’s nameplate indicates 21.5 cubic meters per second.
