water lifting from wells and other water reservoirs. SUBSTANCE: proposed invention relates to devices for lifting of water by means of vibration pumps supplied by renewable power sources. It can be used in different branches of industry and for domestic purpose. Bevels are made at angle of 45 deg minimum relative to pole axis on inner ends of magnetic circuit poles in vibration pump. Outer ends of armatures are made with bevels of the same angle. Bevels on magnetic circuit pole ends and armature ends are arranged for engagement of armature bevels and magnetic circuit bevels at displacement. Winding is placed on magnetic circuit yoke. Use of invention reduces losses for excitation of vibrations of pump armature and possibility is provided for supply of pump from unidirectional pulse source. EFFECT: increased efficiency and power factor, simplified scheme and cost of pump supply source. 3 cl, 3 dwg |
