Abstract

The invention discloses a filtering method of a submersible pump for a silt-proof well, and relates to the technical field of submersible pumps, the submersible pump comprises a submersible pump body, a bearing ring is welded to the surface of the submersible pump body, and a positioning groove is formed in the bottom of the bearing ring. In the using process, a user pushes the adapter ring to rotate in an annular groove, two limiting bolts move in the same direction, and when limiting bolts are completely separated from limiting grooves, limiting bearing is not conducted on a calibration bolt any more; at the moment, the moving capacity of the calibration bolt is not limited any more, a user only needs to hold and fix an annular filter plate and push the annular filter plate downwards to drive a calibration ring and the calibration bolt to move until the disassembly work is completed, a new annular filter plate is taken out for replacement, and then reverse operation is carried out, so that the installation work can be completed; and in the operation process, it is guaranteed that the operation amount is small so that the return work can be rapidly and conveniently completed, and the position state of the annular filter plate is limited by means of the limiting bolts so that position deviation can be prevented.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to a filtering method for submersible pumps used in sand prevention wells. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. The groundwater can be extracted to the surface by submerging the whole unit into the water when in use. It is one of the most commonly used pumps in different occasions that need to transport water resources, such as domestic water, mine rescue and farmland irrigation, and the existing submersible pumps on the market often have additional Install a filter plate to filter and block the submersible pump to prevent large pieces of gravel from entering the pump body and cause damage to the submersible pump. However, because the filter plates of some submersible pumps on the market are often fixed by bolt structures, the filter plate is in the process of installation and disassembly. It is often ne...
