The invention relates to an anchor for fixing the tubing in the string<br />
of the oil extracting wells in the construction of the tubing<br />
installations, plunger pump as a section for blocking the tubing on<br />
the inside of the well string. The anchor for fixing the tubing in the<br />
string of the oil extracting wells provides the tubing fixing by the<br />
fact that a cylindrical body has a higher connection wherein there is<br />
mounted a valve for emptying the anchor, which consists of a<br />
gauged pin, a valve and a valve seat and the slips may displace<br />
radially and perform the reinforcement on the interior side of the<br />
well string, being pushed by a rubber sleeve , which extends in<br />
diameter due to the pressure generated by the oil pumped inside an<br />
enclosure formed by an inner tube, provided with some orifices for<br />
the inlet of the pressurized oil and the rubber sleeve, thereby it<br />
overcoming the force of some plate springs which provide the<br />
withdrawal of the slips and the assembly release, when, by<br />
introducing a supplementary interior pressure, there takes place the<br />
shearing of the gauged pin given by a circular tool in the<br />
construction of the valve for anchor emptying, the pressures from<br />
the inside and the outside being equalized and the rubber sleeve and<br />
the slips returning in the withdrawn position.<br />

This new design solution shows the following improvements over<br />
known alternatives:<br />
- it creates the possibility of oscillatory system operation with a<br />
point of oscillation around its center of mass;<br />
- it is obtained a better and stable centered position of rod spindle to<br />
textile spindle cup which provides enhanced precision for both the<br />
rod axis perpendicularity to the ring frame bank and a better<br />
centered position to ring;<br />
- there are improved indices for production, productivity, power<br />
consumption, quality of processed yarns, reliability.<br />
