Problems with the flow-limiting orifice plate in 70 cubic meter reactors
Thread Content
Which teacher knows what the diameter of the flow-limiting orifice plate is for the intermediate water injection, shaft seal water, top of the tank flushing, and bottom of the tank piping in a 70-cubic-meter polymerization reactor?
You can calculate the requirements for the orifice plate by yourself, based on the pressure drop. Here, water is injected in between, and the orifice plate for the shaft seal is set at around 3 mm. Last edited by limingshuguang on 2009-3-7 16:46.]
The shaft seal water orifice plate in our unit is set at around 6 mm
Those who have worked on such projects know that when testing the system oneself, adjustments need to be made manually, and these adjustments should be based on the sensitivity of the control valves. It’s about 3mm.
It’s best to calculate it yourself! For the specific algorithm, refer to \"HGT 20570.15-95; Installation of Flow Limiting Orifices in Pipelines\" and the \"Throttling Device Design Manual\". This post was last edited by tfx511024 on 2009-3-6 20:00.]
We used 5mm; this needs to be adjusted according to the situation
We made holes of 3mm, but made adjustments one by one based on the performance in actual use after starting the vehicle.
I’m not sure what it is, but we do these things based on calculations using parameters.
