What is the appropriate volume of the siphon barrel in front of the pump? In a sewage pool with the same depth and the same pump, why do some pumps do not need to fill the siphon bucket with water when they are started (they only need to be filled with water when starting the pump for the first time), but one of them needs to fill the siphon bucket with water every time it is started? Is it because the system is not properly sealed or because the siphon barrel volume is inappropriate?
Usually it's because the system is not properly sealed.
How to calculate, waiting for the expert to give the answer. I feel that the bigger the siphon bucket is, the better it can be sucked up. But how to analyze and calculate it specifically?
I calculated it based on this, mainly looking at the diameter and length of the inlet pipe.

I saw the instructions given by the manufacturer and I don’t know how the manufacturer came up with this formula. I have investigated and analyzed it. This formula is not consistent with the actual situation. Siphon buckets with a volume less than 3 times V can absorb water very well, and siphon buckets with a volume greater than 5 times V can also suck up water, but they must be filled with water again before each start.
Then you can ask teacher Guan Xingfan……
If the structure is unreasonable or the sealing is not good, 1000 times is equal to zero!
There is a 5 second dwell buffer based on the flow rate of the pump.
