Energy conservation in submersible pump sets through efficiency improvements using modified slot design and DCR technology

Abstract EN

This paper presents the efficiency improvements in submersible pump sets by increasing the efficiency of squirrel cage induction motor by using Die-cast Copper Rotor (DCR) technology. A new slot design is proposed instead of conventional slot design for accommodating copper conductors for stator and rotor.

The possible efficiency improvements are checked with three varieties of laminations in both motor and pump sides.

The various electrical parameters including the low voltage performance are measured and compared with the existing Copper Fabricated Rotor (CFR) with proposed DCR technology in a range between (5— 10) HP 3 phase wet type watercooled inductionmotors inaccordance with IS9283.

The overall performance of submersible pump sets is also practically verified in accordance with IS 8034.

The cost comparison between the existing CFR and DCR’s are also reported.
