MAIN ELECTRIC PUMP UNIT WITH ATTACHMENTS TO FRAME WITH USE OF BUILT SUPPORTS, AND METHOD FOR IMPROVEMENT OF UNIT CHARACTERISTICS

摘要

FIELD: engines and pumps.SUBSTANCE: unit includes the main pump and an electric motor, which are mounted on a frame. Their shafts are connected through a coupling to a detachable intermediate shaft. Attachments of the pump and the electric motor to common or separate frames are made using high-accuracy built supports adjustable as to height and self-adjusting as to an angle. Attachment surfaces of the pump legs are lifted to the level of common central axis of supply and discharge branch pipes of the pump. Shafts of the pump and the electric motor are connected by means of a compensating double coupling to flexible discs.EFFECT: creation of the main electric pump unit with improved technical and economic characteristics, and namely with reduced noise and vibrations, improved reliability, service life and efficiency.4 cl, 5 dwg
