FIELD: engines and pumps.
SUBSTANCE: drive comprises a cable, at least one electric motor, connected on top with a sub and covered with a jacket connected to the sub. The sub is equipped with a unit of cable sealing and channels to communicate the jacket with the pump inlet and is made from the top part with a connection for the pump and the bottom part with a connection for the electric motor. Parts are joined by a threaded joint. On the upper part there is a cylindrical expansion with an axis displaced relative to the axis of the sub, and the outer detachable joint for the jacket. Outer holes of channels are located below the joint. The unit of cable sealing is arranged at the side of maximum displacement of expansion relative to the sub. The jacket is made of a lower link, with length sufficient to cover an electric motor equipped with process elements to the minimum, as well as mutually replaceable inserts. The lower link is equipped with a lower thread and an upper joint responding to the sub joint, and inserts - with upper and lower joints, which respond to the sub joint and the upper joint of the bottom link. Length of each insert complies with the applied process element or electric motor.
EFFECT: development of a drive with universal collapsible sub and jacket for reduction of costs for manufacturing and storage.
