Generally speaking, before we start the deep well submersible pump 2 inch diameter, we should make the following inspections.
Inspection and treatment of parts and accessories
1) Clean and check the shaft bearing. Change the bearing if its clearance has obviously become larger, if the bearing roller is broken or dotted, or if the roller path is severely worn out. During the installation of shaft bearing, the lubricating grease should take up half or one third of the space in bearing body.
2) Check the wearing condition of impellers and sealing ring. If the bearing wear has surpassed 3 to 5 times of the designed clearance, you should change the bearing.
3) Check the packing sleeve. If the depth of grinding crack has reached 0.1-0.2mm or the packing sleeve is severely corroded, you should repair or change it.
4) Change the packing plate, the padding, the ineffective O shaped seal ring and the elastic sheath on the elastic pin.
5) Check the wearing condition and the cavitation erosion condition of impeller vanes and coverplate. Repair or change it when necessary.
6) Check the wearing condition of the mechanical seal. Make sure if it is necessary to change the mechanical seal.
7) Change the fastenings that are badly corroded or damaged. When you have finished reassembling the pump, you should debug it again.
Stainless steel material, good quality speaks for itself.
Tight sealing
The deep well submersible pump adopts dual-seal motor. With optimized design, the seal system is safe and reliable.
High efficiency and energy-saving
The deep well submersible pump 2 inch diameter has new floating impellers, with no axial force, better performance.
Better universality
The heads and motors of APK submersible pumps are in uniformed sizes and match well. They can be exchanged freely in installation.
Longer service life
The deep well submersible pump adopts fully oil-immersed copper wire motor that has high efficiency, longer service life and is not easy to get burned.
