Takes the place of a standard pump intake ? Is used in applications where free gas causes interference with pump performance ? Separates a portion of the free gas from the fluid entering the intake to improve pump performance ? Rotary gas separator types include: – Induced Vortex with passive chamber – Rotating chamber 95 The Gas Separator 96 The Seal Chamber Section ? Is located between the pump and motor ? Transfers the motor torque to the pump shaft ? Isolates (seals) the well fluid from the clean motor oil ? Equalizes the internal unit and wellbore pressure ? Provides area for motor oil expansion volume ? Absorbs the pump shaft thrust load ? The Four “Shuns” expansion, equalization, isolation, amp。 Braid or Lead Sheath (Low Temp or Hi Temp) 5 Armor (Low Profile Galv, SS, or Monel) ?

Protects the downhole equipment from under amp。 Benefits ? Available with any standard cable ? A variety of capillary tube sizes are utilized ? Available in round or flat profile ? Allows targeted delivery of treatment chemical ? Single or dual capillary designs ? Instrument wire can be inserted in some capillary tube sizes ? An outer layer of armor is applied to protect the capillary tubes Standard Power Cable Capillary Tubes Capillary Tube 189 Power Cable Application Proper application of ESP cable requires ... ? Limiting voltage drop to no more than 30 volts per 1000? and less than 15% of motor volts by choosing a sufficiently large conductor (AWG) size ? Choosing the proper profile based on tubing thread size vs. casing ID amp。 current ? Is a two pole, three phase, AC, induction type ? Rotates at approximately 3500 RPM at 60 Hertz ? Is constructed of rotors and bearings stacked on the shaft and loaded in a wound stator ? Contains synthetic oil for lubrication ? Relies on fluid flow past the housing OD for cooling 170 Motor Components Stator Laminations KaptonWrapped Mag Wire Rotor Bearing with Tring Housing Epoxy Encapsulation 171 rotor Bearing with TRing Stator 172 Stator Laminations on a Mandrel 173 Stator Laminations pressed into the motor housing 174 A wound Stator with Leads attached 175 Rotor Copper End Ring Rotor Laminations Rotor Bearing Rotor T ring Rotor Spacers 176 Rotor Bearing Rotor 177 Motor Performance ?
