Abstract
Изобретение относитс к горной промышленности . Цель - повышение надежности работы устройства за счет возможности уменьшени износа сальников . Устройство состоит из разъемного цилиндрического корпуса 1 с крышкой (К) 2. В корпусе 1 установлены нажимные втулки (НВ)4- 6. Внутренн поверхность корпуса 1 и НВ 4-6 выполнена конусной. В корпусе 1 размещены верхний 7 и нижний 8 сальники (С), а в К 2 - центрирующий узел полированного штока 14. Последний выполнен в виде полого цилиндра с осевым пазом. В нем установлен ползун. Нижний С 8 размещен между НВ 4 и 5, которые обращены своими внутренними конусными поверхност ми навстречу друг другу. Верхний С 7 установлен в корпусе 1 на уровне его внутренней конусной поверхности, В К 2 находитс также уплотнительный элемент 11. Внутренн полость корпуса 1 между С 7 и 8 и над ними заполнена смазывающим материалом . Рабочим вл етс верхний С 7, а резервным - нижний С 8. При износе С 7 полированный шток 14 уплотн етс с по- мощью нижнего С 8, после чего замен ют набивку в С 7 и заполн ют внутренние полости корпуса 1 смазывающим материалом . 2 ил. ЁThe invention relates to the mining industry. The goal is to increase the reliability of the device due to the possibility of reducing wear of the glands. The device consists of a detachable cylindrical housing 1 with a lid (K) 2. In the housing 1, pressure bushings (HB) 4-6 are installed. The inner surface of the housing 1 and HB 4-6 is tapered. In case 1, the upper 7 and lower 8 glands (C) are placed, and in K 2 - the centering unit of the polished rod 14. The latter is made in the form of a hollow cylinder with an axial groove. It has a slider. The lower C 8 is placed between HB 4 and 5, which face their inner conical surfaces towards each other. The upper C 7 is installed in the housing 1 at the level of its inner conical surface. In K 2 there is also a sealing element 11. The internal cavity of the housing 1 between C 7 and 8 and above them is filled with a lubricant. The upper C 7 is working, and the lower C 8 is reserved. When the C 7 is worn, the polished rod 14 is compacted with the lower C 8, after which the packing in C 7 is replaced and the internal cavities of the housing 1 are filled with lubricant. 2 Il. Yo
