FIELD: engines and pumps.
SUBSTANCE: pressure transducers are arranged at pump inlet and inside it. Suction valve composed of solenoid valve to allow hole fluid to pass in under-plunger chamber without drag or flow discontinuity. Suction valve electromagnet ad pressure transducers are connected via data and actuation lines with the surface control station. Said suction valve is opened/closed in synchronism with up/down stroke of the plunger owing to continuous comparison of pump inside pressure and that at its inlet by control station and timely feed of commands to valve solenoid. Forced operation of suction valve allows complete filling of pump inner chamber even at higher thickness of hole fluid and formation of bitumen-pitch-paraffin sediments at suction valve elements.
EFFECT: higher efficiency.
