Fig. 1 is structural representation of the present utility model;
In figure: 1, upper connection, 2, outer sleeve, 3, pump barrel, 4, plunger piston assembly, 5, lower contact, 6, oiling valve.
Embodiment
As shown in Figure 1, the utility model provides a kind of integeral tube pumping pump, can realize downhole crude and promote, and can improve intensity and the rigidity of pump barrel, thus solve the problem of the integeral tube pumping pump pump barrel compressive deformation of reinforced pump barrel, improve its applicability.The utility model forms primarily of upper connection 1, outer sleeve 2, pump barrel 3, plunger piston assembly 4, lower contact 5 and oiling valve 6; Wherein, there is internal thread at the two ends of upper connection 1 and lower contact 5, and be threaded at the two ends up and down of outer sleeve 2 upper connection 1 and a lower contact 5 respectively; In outer sleeve 2, be arranged with pump barrel 3, pump barrel 3 lower end is connected with the pump barrel internal thread of lower contact 5, and pump barrel internal thread is positioned at the below of the internal thread be connected with outer sleeve 2 lower end set by lower contact 5 upper end.Pump barrel 3 upper end is suspended on righting place of upper connection 1.Pump barrel 3 only lower end is connected with the pump barrel internal thread of the lower contact 5 of outer sleeve 2 lower end, and upper end is unsettled, solves the problem of the integeral tube pumping pump pump barrel compressive deformation of reinforced pump barrel, improves its applicability, avoid pump barrel and bear pressure at axial direction.Plunger piston assembly 4 is positioned at pump barrel 3, and plunger piston assembly 4 and pump barrel 3 are slidably matched, and oiling valve 6 is threaded on the internal thread of the lower contact 5 being positioned at outer sleeve 2 lower end.From above structure, for lower contact 5, its lower end is oil pipe internal thread, and upper end is the composite structure of oil pipe internal thread and pump barrel internal thread.
Wherein pump barrel 3, plunger piston assembly 4 and oiling valve 6 are existing products, do not describe in detail, can see Chinese patent: ZL201020579945.0.
Outer sleeve 2 of the present utility model is connected with the oil pipe internal thread of upper connection 1 and lower contact 5, and the support of composition oil well pump, plays a protective role to the pump barrel 3 of its inside; Pump barrel 3 only lower end is connected with the pump barrel internal thread of the lower contact 5 of outer sleeve 2 lower end, and upper end is unsettled, solves the problem of the integeral tube pumping pump pump barrel compressive deformation of reinforced pump barrel, improves its applicability, avoid pump barrel and bear pressure at axial direction.
