Description
диаметра ниппел (муфты). Кольцо 11 закрепл етс на ниппельной 1 части, например , с помощью кле и защищает наружную поверхность ниппел (муфты) от износа стенки скважины и внутреннюю поверхность обсадной колонны от абразивного износа.;the diameter of the nipple (coupling). The ring 11 is fixed on the nipple 1 part, for example, with glue and protects the outer surface of the nipple (sleeve) from wear on the borehole wall and the inner surface of the casing from abrasive wear .;
Сборка соединени заключаетс в установке стопорного кольца 5 в конце .муфты 2 на цилиндрической резьбе 6 (фиг. 1) или на конической резьбе 8 (фиг. 2). Фиксирование стопорного кольца 5 от проворота осуществл етс установкой шпонок 7 (фиг. 1) или на самоотверждающемс клее 9 (фиг. 2). Свинчивание соединени осуществл етс с предварительно установленным и закрепленным унлотнительным кольцом 11, с муфтой 2 на основной конической резьбе 3 с крут щим моментом, необходимым дл сведени кулачкового зацеплени . The assembly of the joint consists in mounting a retaining ring 5 at the end of the coupling 2 on the cylindrical thread 6 (Fig. 1) or on the tapered thread 8 (Fig. 2). The locking ring 5 is secured against rotation by installing the keys 7 (Fig. 1) or on the self-curing adhesive 9 (Fig. 2). The joint is screwed with a pre-installed and secured sealing ring 11, with a coupling 2 on the main conical thread 3 with the torque required to reduce the cam engagement.
Необходима надежность уплотнени резьбового соединени при сборке определ етс положением кулачковых поверхностей 4, которое задаетс по величине нат га и обеспечиваетс монтажной зат жкой резьбы 3.The required reliability of sealing the threaded joint during assembly is determined by the position of the cam surfaces 4, which is determined by the tension value and is provided by the assembly tightening of the thread 3.
Зацепление кулачковых поверхностей 4, исключа доворот основной резьбы, разгружает ее при эксплуатации бурильных труб, обеспечива стабильность напр женного состо ни соединени .The engagement of the cam surfaces 4, excluding the turning of the main thread, unloads it during the use of drill pipes, ensuring the stability of the stressed state of the joint.
Применение резьбового соединени легкосплавных бурильных труб гарантирует существенное повышение надежности и долговечности работы соединени за счет исключени доворота резьбы крут щим моментом в осложненных услови х эксплуатации , обеспечиваемое кулачковым зацеплением , снижени абразивного износа наружной поверхности зоны резьбового соединени .The use of a threaded joint of light-alloy drill pipes ensures a substantial increase in the reliability and durability of the joint by eliminating the twisting of the thread torque in complicated operating conditions provided by the cam gear, reducing the abrasive wear of the outer surface of the threaded joint.
