Description

При эксплуатации буровых установок регулировка тормозного момента производитс  периодически изменением уровн  наполнени  тормоза .During the operation of drilling rigs, the adjustment of the braking torque is made periodically by changing the filling level of the brake.

Описываемый способ регулировки тормозного момента отличаетс  от известных тем, что наполиение гидравлического тормоза производитс  принудительно в процессе спуска каждой свечи. Благодар  такому способу значительно ускор етс  процесс спуска труб в скважину.The described method of adjusting the braking torque differs from that known in that the filling of the hydraulic brake is forced during the descent of each spark plug. Thanks to this method, the process of lowering pipes into the well is significantly accelerated.

Согласно принципиальной схемы регулировки момента гидравлических тормозов, гидравлический тормоз / (см. чертеж) соединен с холодильником 2 и с центробежным насосом 5. В местах соединени  установлены вентили 4, регулирующие поступление из насоса жидкости в тормоз и слив ее в холодильник.According to the concept of adjusting the torque of the hydraulic brakes, the hydraulic brake / (see drawing) is connected to the refrigerator 2 and to the centrifugal pump 5. At the junction points, valves 4 are installed that regulate the flow of fluid from the pump into the brake and drain it into the refrigerator.

Холодильник устанавливаетс  так, чтобы верхний уровень воды в нем был ниже ротора тормоза.The refrigerator is installed so that the upper water level in it is below the brake rotor.

В начале спуска каждой свечи вода в пористый тормоз подаетс  с помощью небольщого центробежного насоса. Объем подаваемой в тормоз лсидкости постепенно увеличиваетс  по мере спуска свечи, в св зи с этим увеличиваетс  и тормозной момент, в соответствии с объемом наход щейс  в тормозе воды. После спуска свечи вода самотеком сливаетс  в холодильник.At the beginning of the descent of each candle, water is supplied to the porous brake using a small centrifugal pump. The volume of fluid flow into the brake gradually increases as the candle is lowered, and therefore the braking torque increases in accordance with the volume of water in the brake. After the candle is lowered, the water is drained by gravity into the refrigerator.

Привод насоса осуществл ют с помощью ценной передачи от гидравлического тормоза или же от электродвигател , автоматически включаемого с пункта управлени .The pump is driven by a valuable transmission from a hydraulic brake or from an electric motor that is automatically activated from the control point.

Предмет изобретени Subject invention

Способ регулировки тормозного момента гидравлических тормозов буровых установок, отличающийс  тем, что, с целью ускорени  спуска труб в скважину наполнение гидравлического тормоза осуществл ют при помощи насоса в процессе спуска каждой свечи, при этом количество подаваемой рабочей жидкости увеличиваетс  с увеличением веса колонны труб и скорости спуска инструмента.The method of adjusting the braking moment of hydraulic brakes of drilling rigs, characterized in that, in order to accelerate the descent of pipes into the well, the hydraulic brakes are filled with a pump during the descent of each candle, while the amount of working fluid supplied increases with increasing weight of the pipe string and descent rate tool.
