Improvements in mechanical seal for pumps, progressive cavity mancalizado

摘要

Improvements in mechanical seal mancalizado for progressive cavity pumps, which apply to a mechanical seal (1) in the form of a cylindrical body, hosting a central inner sleeve (2) which fits perfectly to the polished rod (3) of the pump.The inner sleeve centered (2) moved by a device clamp bottom (2a) which fits perfectly and sympathetic stem polished (3) of the pump, allows axial movements of the rod, and its main purpose is to prevent ejection of the same in cases of rupture by fatigue of M. Material or caused by sudden reversals.In the current limited by the bottom flange of a motor reducer (s); an area of central contour (6) identifies the location of the actuation of the components of the mechanical seal itself, as spacers, bearings, seals, sealing rings and others; in a typical installation in the well pet Rolu00edfero on land, the invention includes mechanical seal itself (1).Above which is the whole motor reducer (m). Whereas, below this mechanical seal, is coupled to the safety deposit box door "clamp" (4), which is connected to said mechanical seal by means of a flange (7). While a bottom flange (8) makes the connection with the 'flow (9).That is, immediately below this is the flange reduction (L0), this encimando the head of the coating (11); the invention itself includes an housing security door "clamp" (4) which, in use, releasing the "clamp" itself (19).And by the use of metallic cylindrical collector (26) in the form of a small plug external to the body of the mechanical seal (1), and the 'flow (9) to be original in all facilities.
