On said apparatus oil pipe four-way, hanger pressure cap presses rotating eccentricity hanger, its rotating eccentricity hanger upper end be connected standpipe be connected, lower end is connected with oil pipe.The another side of oil pipe four-way is connected with hanger pressure cap.
Polished rod seal seat and the eccentric 5mm. in well head center is sealed in said apparatus
In said apparatus, seal polished rod seal seat can 360 degree of rotations.
In said apparatus, lower rotation hanger is designed to rotary rotating eccentricity hanger, eccentric distance 17mm.
Filler seat tuningout active joint in sucker rod polished rod position deviation in said apparatus.
In said apparatus, when changing packing box, unclamp airtight and watertight padding pressure cap, oblique incision sealed packing.
In said apparatus, seal polished rod seal seat be connected with rotating eccentricity hanger.
In said apparatus rotary rotating eccentricity hanger upper end be connected standpipe and connect, lower end is connected with oil pipe.
Above technical characteristic constitutes best case study on implementation of the present utility model, have install and use easy to operate, alleviate in-site installation personnel labor intensity, increase work efficiency, increase the advantage of life of equipment, non-essential technical characteristic can be increased and decreased according to actual needs, meet the demand of different situations.
The utility model reasonable in design is compact; adopt anti-bias shaft mouth test apparatus; can be implemented in certain scope of design automatically to adjust and make polished rod and equipment concentric problem; solve when changing packing box; pressure flow in the valve pocket of rubber gate; emptying, protection flashboard, improves flashboard problem in application life.When changing packing box, not needing sealed packing to enter to be pressed in sealer from oil-extractor polish-rod cover, carrying out employing operation after polished rod is connected with pumping unit hanging lanyard, alleviate the labour intensity of site operation installation personnel, improve operating efficiency.
