BOREHOLE ELECTRONIC UNIT FOR BOREHOLE ELECTRICALLY DRIVEN PUMP

摘要

FIELD: engines and pumps.SUBSTANCE: proposed electronic unit can be used for control over borehole motor. It comprises cylindrical case 1 closed at ends by base 3 and head 2 facing the motor, electronic circuit components arranged in sealed compartment, cable glands for connection of electronic components with motor circuits and plug-in terminal of contacts 7, 9. Said unit comprises chassis 11 of segmental cross-section made of material that features high heat and electric conductance. Chassis 11 is arranged to get in thermal contact with inner surface of case 1. Electronic circuit power components 12, particularly those fitted at the chassis 11 flat surface are electrically connected with cable glands. Joint between case 1 and base 3 and head 2 are sealed to sustain high pressure and to make sealed compartment with base 3, head 2 and case interior.EFFECT: expanded operating performances.5 cl, 2 dwg
