Calculation of outlet flow rate of chlorine compressor
Thread Content
The chlorine compressor produced by Siemens in Germany has four-stage compression, the relationship between the outlet flow rate, the chlorine inlet guide impeller opening, the return valve opening, and the outlet pressure. It is best to have a quantitative formula.
I guess for such a professional question, you have to ask the manufacturer, or you can post it to the mobile equipment section.

This formula can be found in our DCS backend, but I always felt it was wrong at first and after confirming with the manufacturer, I modified it once. We need to check the instrument information to find out. This traffic is not the essence of 3K. It would be great if we could get the adjustment logic of the return valve according to each parameter. It is safer and more stable to directly remove the PLC and use DCS entirely.
I just want to understand the changing pattern of traffic. Our 3k traffic jumped when the traffic approached 10,000 cubic meters.
How come the car jumps when the traffic is high? It will only jump if it is too low to prevent panting. Then you need to check why it jumped (the flow rate is too high, the load is high, and the motor is overloaded and jumped? ), the interlocking logic has no high traffic jumps. In the past two days, I asked our instrument DCS to check the formula in the background.
Anyway, the bus jumped once when the traffic volume was almost 9,600 cubic meters. The real reason was not found that time. There is no flow interlock on the dcs interlock. Thanks for the formula.

Siemens has many interlocks for the absolute safety of the equipment, but due to the stability of the measurement, most interlocked stops are probably unnecessary. IO failure, poor contact, card failure, stray current interference, etc.
This formula is only the conversion between standard square meter and actual flow rate, and also how to calculate the working condition flow rate.
The working conditions are actually measured by Siemens' own differential pressure orifice flowmeter. Don't you have it?
Oh, that one was installed on the on-site pipe, it seems like it was dismantled in our factory. There is traffic on the DCS outlet. What is the traffic?
