Timed shutdown of yellow phosphorus submersible pump
Thread Content
Our company produces phosphorus trichloride, using liquid yellow phosphorus as raw material and a submersible pump for transportation. However, it is common to encounter situations where the phosphorus storage tank gets clogged due to improper handling of the phosphorus, or where the tank gets filled to capacity because the timing for adding phosphorus was forgotten, resulting in even overflow. I would like to ask the experts here: is it possible to find a device that can shut off the submersible pump after a set time, so that the phosphorus pumping system stops automatically after a few minutes, thereby ensuring the intrinsical safety of the equipment? Thank you all!
Find an electrician; a price/time relay should do the trick! If I, a beginner in electrical work, make mistakes, please don’t laugh at me!
Add a level gauge to automatically start and stop the pump
Thank you, are there any other suggestions?
Are there any good models of time relays to recommend?
Install a level gauge that stops operation when it’s full and starts it up again when the level is low.
Level gauges can get stuck sometimes, which poses a significant risk; it’s safer to cut off the power regularly!
