Description
клОН ющего устройства распределитель 11 ие изменит своего положени .The clone distributor 11 does not change its position.
Посл€ начала циркул ции поток промывочной жидкости проходит через промывочное отверстие 12, а также через зазоры между распределителем и корпусом 4 во все полости отклон ющего устройства. Проход через отверсти 5, промывочна жидкость создает давление, пропорциональное величине расхода жидкости, проход щей через каждую гидрокамеру . Вследствие этого, давление в гидрокамерах , доступ в которые открыт через промывочное отверстие 12, всегда больше, чем во всех прочих гидрокамерах, куда поток жидкости попадает, проход через малый зазор между распределителем 11 и корпусом 4. При создании перепада давлеии внутри гидрокамер отклон ющего устройства на все плунжеры будет действовать выталкивающа сила, направленна от оси турбобура; величина этой силы будет пропорцнональиа развиваемому давлению, то есть расходу жидкости, проход щей через каждую гидрокамеру. На плунжеры в гидрокамерах, доступ в которые открыт отверстием 12, будут действовать больщие силы давлеии , чем на плунжеры, расположенные в других гидро-камерах, в результате чего эти плунжеры выдвинутс в заданном направлении, одновременно заперев все прочие, благодар наличию гибкой т ги 10. Измен на поверхности конфигурацию и расположение отверсти 12 относительно ут жел юще1 о элемента участка 13, измёй ют направление, в котором будут выдвигатьс илунж.еры, выдвигающие щтоки 7 и бащмаки 9 до упора со стенкой скважины, обеспечива After the circulation begins, the flushing fluid flows through the flushing hole 12, as well as through the gaps between the distributor and the housing 4 into all the cavities of the deflecting device. The passage through the ports 5, the flushing fluid, creates a pressure proportional to the flow rate of the fluid passing through each hydrochamber. As a result, the pressure in the hydrochambers, which are opened through the washing port 12, is always greater than in all other hydrochambers, where the fluid flow reaches, the passage through the small gap between the distributor 11 and the housing 4. When creating a pressure differential inside the hydrochamber of the diverting device all plungers will have an ejection force directed from the axis of the turbo-drill; the magnitude of this force will be proportional to the pressure developed, i.e. the flow rate of the fluid passing through each hydrochamber. The plungers in the hydraulic chambers, which are opened by the opening 12, will have greater pressure than the plungers located in other hydraulic chambers, as a result of which the plungers move in a given direction, at the same time locking all the others, due to the flexible pull 10 The change in the surface configuration and location of the hole 12 relative to the utterly desirable element of section 13 will change the direction in which the sliters will extend, extending the rods 7 and the strut 9 up to the stop with the borehole wall, providing

The reliability of the operation of the described device is ensured by the absence of any mechanical or other transmissions that can fail in the process of working at the bottom.
