FILTER INLET MODULE OF SUBMERSIBLE ELECTRIC CENTROFUGAL PUMP Russian patent published in 2023 - IPC F04D29/70 

FIELD: petroleum engineering.

SUBSTANCE: invention relates to petroleum engineering and can be used in the design of submersible electric submersible pumps for receiving and cleaning the produced product from mechanical impurities. The filter is an inlet module of a submersible electric centrifugal pump, containing a housing in the form of a cylindrical perforated pipe with threaded ends, while the threaded ends are made with the possibility of threaded connection at the upper end of the housing with a head, and at the lower end of the housing with a sub or base, while the head, sub and the base contains a bearing assembly of the shaft, made in such a way that in the installed state the bearing assembly is located outside the boundaries of the housing, while a filter is hermetically installed on the housing, including a filter element containing corrugation.

EFFECT: increasing the efficiency of both the operation of the filter of the input module, and the cleaning of the produced production of wells equipped with installations of submersible electric centrifugal pumps with a decrease in the outer diameter of the module.
