Abstract

Inventia se refera la un racord pentru prajinile de pompare avînd utilizare în industria petrolului. Racordul pentru prajinile de pompare este caracterizat prin aceea ca cepul de îmbinare a prajinii la baza mufei prezinta o degajare exterioara sub care se afla o portiune cilindrica care are, fie aceeasi axa longitudinala si acelasi diametru exterior cu axa si diametrul cepului si cu diametrul dintre vîrfurile filetului mufei, fiind racordata cu prajina printr-o portiune semihiperboloidala si avînd lungimea necesara prinderii în elevator, fie ca are un diametru exterior mai mare decît a cepului, longitudinala excentrica pentru a bloca rotirea cepului în mufa, iar mufa este prevazuta sau nu, cu o portiune semihiperboloidala exterioara de întregire a portiunii semihiperboloidale a cepului de reazem în elevator si un locas în interior pentru doua bacuri curbe, simetrice, mentinute în contact cu cepul de un cilindru turnat între ele de un inel elastic, turnarea cilindrului fiind realizata printr-un orificiu.The invention relates to a connection for pumping pads having use in the oil industry. The connection for the pumping pads is characterized in that the coupling pin on the base of the coupling has an outer recess under which there is a cylindrical portion having either the same longitudinal axis and the same outer diameter with the axis and the diameter of the pin and the diameter of the peaks of the thread of the plug, being connected to the ground by a semi-pyramidal portion and having the length required to attach to the elevator, or having a larger outer diameter than the pin, the eccentric longitudinal to block the rotation of the pin in the plug, and the plug is provided or not a semi-semi-erboidal outer portion for completing the semi-liperboloidal portion of the support pin in the elevator and an interior seat for two symmetrical curved bridges maintained in contact with the pin of a cylinder molded between them by an elastic ring, the casting of the cylinder being made by hole.
