What inspections need to be done before deep well pump goes down
1. The corresponding plane of the well pipe nozzle protruding from the foundation should not be less than 25 mm;
2. The inner diameter and verticality of the well pipe should meet the requirements of the pump’s entry into the well. The inner diameter of the well should generally be about 50 mm larger than the maximum dimension of the pump into the well, so that the pump body can be freely up and down in the well and must not damage the submersible cable. ;
3. There should be no sludge, dirt and debris in the well pipe;
4. The size of the top middle void of the foundation shall meet the requirements for the connection of the lift pipe to the pump base;
5. Lifting water pipe should be straight, thread and flange end should not be bruised, and should be cleaned;
