Description
(54) УСТРОЙСТВО ДЛЯ СМАЗКН ОПОР ШАРОШЕК РАСШИРИТЕЛЯ(54) DEVICE FOR SMAZKN SUPPORT OF EXTENSION BALLS
1one
Изобретение относитс к устройствам дл смазки опор шарошек расширител , преимущественно при бурении .скважин большо1 диаметра с использованием промывочной жидкости.The invention relates to devices for lubricating the cone reamer supports, preferably while drilling large diameter wells using a washing liquid.
Известны устройства дл смазки онор шарошек расширител , содержащие эластичную камеру дл смазочного материала, соединенную с полостью опор с помошыо системы каналов.There are known devices for lubricating onor cones of an expander, containing an elastic chamber for a lubricant connected to the cavity of the supports by means of a channel system.
Предлагаемое устройство отличаетс от известных тем, что элпг;тнч1ш камера расположена в направл юшей части расширител ниже уровн опор шарошек, 3io повышае эффективность сиазки опор шарошек расширител .The proposed device differs from the known ones by the fact that the camera is located in the direction of the expander below the level of the supports of the cutters, 3io increases the efficiency of the design of the supports of the cutters of the extender.
Па чортежо изображено предлагаемое устройство.Pa Chortejo shows the proposed device.
Устройство дл смазки /мюр шарошек рысширнтел сг.держит 3jiai:Tii4iiyH камеру 1 дн жидкого смазочного материала, расположенную в направл ющей час/ги рас-ширител 2 ниже уровн опор 3 шарошек. Система каналов 4 соедин ет полости онор 3 с эластичной ка;.герой 1.The device for lubrication / murr of shovels ryshshirntel sg. Holds 3jiai: Tii4iiyH a chamber of 1 day of liquid lubricant located in the guide of the hour / g extender 2 below the level of the supports 3 of cones. The system of channels 4 connects the cavities of the onor 3 with the elastic core; hero 1.
При погружении расширител в скважину, заполненную промывочной жидкостью, в эластичной камере 1 за счет разницы удельных весов смазочного материала и промывочной жидкости воз1шкает избыточное давление. Под действием этого давлени смазочный материал поднимаетс вверх и по каналам 4 поступает в полости опорЗ шарошек расширител , обеспечива их посто нную эффективную смазку.When the expander is immersed in a well filled with flushing fluid, in an elastic chamber 1 due to the difference in the specific gravities of the lubricant and the flushing fluid, an overpressure occurs. Under the action of this pressure, the lubricant rises upwards and through the channels 4 enters the cavities of the supports of the cones of the expander, ensuring their constant effective lubrication.
