Установка работает следующим образом. »Installation works as follows. "

Откачиваевая жидкость по входным соплам 1-4 попадает в,секции 1315 15 гидроциклона, приобретает сильное вращательное движение и делится по фазам. Осветленная жидкость через отвод 11 направляется в кожух 12, а. оттуда откачивается погружным насо- jg сом 6. . ,The pumping liquid through the inlet nozzles 1-4 enters, sections 1315 15 of the hydrocyclone, acquires a strong rotational movement and is divided into phases. The clarified liquid through the outlet 11 is sent to the casing 12, and. from there it is pumped out by a submersible pump jg som 6.. ,

Осадок, отброшенный под действием центробежных сил к гидроэлеватору 9, эжектируется в пульпоотводящую трубу 10. Рабочий расход активного соп- 25 ла 8 гидроэлеватора 9 обеспечивается ' из нагнетательного патрубка 7 погружного насоса 6. Эжектируемая пульпа по пульпоотводящей трубе 10 подается в нагнетательный патрубок 7 и вместе с jg основным потоком погружного насоса 6 поднимается на поверхность.The sludge discarded by centrifugal forces to the hydraulic elevator 9 is ejected into the pulp pipe 10. The working flow rate of the active nozzle 25 l 8 of the hydraulic elevator 9 is provided from the discharge pipe 7 of the submersible pump 6. The ejected pulp is fed through the pulp pipe 10 to the discharge pipe 7 and together with jg the main stream of the submersible pump 6 rises to the surface.

Выполнение всасывающего патрубка в виде установленного в скважине кожуха и размещение в нем по меньшей мере трех секций гидроциклона позволяет более эффективно откачивать пульпу из различных по диаметру и притоку гидросмеси скважин благодаря уменьшению диаметра гидроциклона, что существенно сокращает затраты на транспортирование пульпы.The implementation of the suction pipe in the form of a casing installed in the well and placement of at least three sections of the hydrocyclone in it allows more efficient pumping out the pulp from wells with different diameters and inflows due to a decrease in the diameter of the hydrocyclone, which significantly reduces the cost of transporting the pulp.
