The issue of reduced compressor capacity
Thread Content
We have newly installed five compressors in our facility: three for raw gas (semi-water gas) and two for purge gas. The system has not yet been put into operation. I would like to know through which means it is best to adjust the production volume if necessary during the manufacturing process
Can a reciprocating compressor be adjusted through its primary inlet, unloader, and return line? Where is the best place to use it? Why. . . Experts, please provide a solution. Thank you
There are also questions regarding the inter-stage liquid separation tanks: if waste liquid is discharged, what methods are used to determine when the discharge process is complete? Level gauge? Listen to the sound? I still feel the temperature. Is the temperature higher in the liquid or in the gas inside the separator tank? Why? Those with experience, please explain. . . I thank you, sir
It’s usually adjusted using a unloader; just click a few times in the control room~ But any of the methods you mentioned will work as well.
I hope some expert can help clear up my doubts, so that I can gain more knowledge too:P
The pressure is reduced by the inlet return valve; during the drainage of oil and water, the drain valves in each section are used. When a loud noise is heard when these valves are opened, or when air is present in the mixture of oil and water, the valves can be closed； Of course, there are other ways as well; I hope experts can offer more guidance
What the people upstairs said is all correct. I’ve also considered these factors, but since I’ve never worked with compressors before and I’m not currently working on any projects, I’m not sure which one would be the best. I hope experts can explain in detail which type is the best, especially in terms of minimizing pressure fluctuations. Thank you very much
There are many ways to do this. Frequency conversion works, and if electricity costs aren’t a concern, then reversing the flow of fluid can be used, as well as reducing the inlet pressure. It depends on which method you choose
Our press doesn’t have variable frequency; do you mean the return flow is from the outlet to the inlet? Will reducing import pressure cause fluctuations in pressure? I mean, compared to exporting back to the origin, is it more likely to cause fluctuations?
You can just add an inverter drive; it’s more cost-effective compared to using a recirculation system. With recirculation, the inlet temperature tends to be higher, unless there are devices for cooling the air, such as heat exchangers. If you connect the inlet and outlet directly for recirculation, then the inlet temperature will definitely be high, and accordingly, the exhaust temperature will also be high. It’s recommended to use an inverter drive. Here, we use inverter drives with fixed-frequency motors – which is a good solution
