Savyuk L. Prognosis of technical condition of devices of electrocenttrifugal pump for extraction of oil.

The dissertation is dedicate the problems of the rise of lasting and capacity for work of electrocentrifugal pump for extraction of oil by prognosing of it's full refusal in cause of precipict and fooling down in the well of parts of devices in (F - refusal). The nature of appearance of F-refusal into parts of screw junction was investigated by using mathematical models of the system "УЕЦН-КНКТ" and models of screw junction. The new methods and new thecnical and program support were build. The conformity of chaining of coefficient of strength of screw function was extablished. The new methods of prognosis of П-refusal system in the way of discovery of rational diagnostic sing and methods of prognosis of remained resources of the system were offered.
