What to do if a deep well pump falls in?
Thread Content
During the process of lifting out a company’s 300M deep-well submersible pump for maintenance, the last section of the pump fell back into the well due to bolt corrosion. How do people usually handle such situations? If the pump is not removed, will it affect the water output in the future?
It’s impossible to retrieve it, and it won’t affect the water output later on.
It can only be placed inside; it has no impact on the new pump.
Objects experience buoyancy in water. If the cable is not broken, one can use the cable to pull the pump towards the surface; with proper safety measures in place, a diver can put on a wetsuit, go down, secure the pump, and then pull it back up.
Can people go down 300 meters? Who’s going down? Adults can’t get in at the wellhead either.
There’s no need to worry about it; you can give up. Even if it has an impact later on, there’s nothing that can be done about it. Or consider the method from the 4th floor – find someone with a shoulder width of no more than 30 centimeters, have them put on a wetsuit and dive to 300 meters underwater to retrieve it: lol
Everything I want to say makes you all feel embarrassed. We consulted several companies specialized in deep-well recovery; one charged 100,000, and another 20,000. It can be salvaged. And a lot have been recovered. What we ended up doing was to install a new pump directly; it has been running for a few days now and the water output is normal.
Replace it directly with a new one. . . . . .
It’s quite common for the suction pipe of a deep well pump to fall into the well; a clamp can be used to retrieve it, and the cost is only in the tens of thousands of yuan. There are many people around who do this kind of work, and it doesn’t require much technical skill
There’s no need to worry about it for now, unless a lot of them fall down below.:D Just introduce the new pump
Don’t worry about it for now; just install a new pump. Wait until more things fall in there, and then deal with the retrieval together
