The specific embodiment
About the present invention is the application target that reaches above-mentioned and effect and the technological means that adopts, now enumerate better feasible embodiment, and coordinate shown in accompanying drawing, details are as follows:
First as shown in Figure 1, be the sectional view of direct conduction type oil pumper bottom fitting of the present invention.The outside of described sub-joint 1 has multi-stage stairs, by top to the bottom convergent of sub-joint 1.In a preferred embodiment of the invention, the outside of described sub-joint 1 is provided with level Four step altogether, by top to bottom, is followed successively by first step 11, second step 12, the 3rd step 13 and the 4th step 14.The inside of described sub-joint 1 is provided with shoulder hole, top to bottom convergent by sub-joint 1, the corresponding first step 11 of its neutron joint 1 is provided with the first shoulder hole 111 and the second shoulder hole 112, the second described shoulder hole 112 inwalls are provided with screw thread, with hollow rod 3(Fig. 3) thread segment be connected, corresponding second step 12 is provided with the 3rd shoulder hole 113, and the 3rd described shoulder hole 113 is not communicated to the bottom of sub-joint 1.The spaced surface of described second step 12 is provided with a plurality of connectivity slots 121, and described connectivity slot 121 is communicated with the 3rd described shoulder hole 113, and the liquid of extracting out is entered in the hollow rod 3 being connected with sub-joint 1.
Again as shown in Figure 2, described sub-joint 1 is provided with the female joint 2 being mated, and is provided with level Four shoulder hole (the first shoulder hole 21, the second shoulder hole 22, the 3rd shoulder hole 23, four-step hole 24) and matches with first step 11, second step 12, the 3rd step 13 and the 4th step 14 of sub-joint 1 respectively in described female joint 2.Described female joint 2 is also provided with the connectivity slot 25 corresponding with sub-joint 1, when group joint 1 connects together with female joint 2, the connectivity slot 25 of described female joint 2 has part to connect with the connectivity slot 121 of sub-joint 1, thereby the liquid of extracting out is entered in the hollow rod 3 being connected with sub-joint 1.
Wherein, each described step is equipped with body 15 in electrical contact on (11,12,13,14), is provided with and can forms the body in electrical contact 16 being electrically connected to body 15 in electrical contact in female joint 2, and sub-joint 1 is connected by viscose with female joint 2.Group joint 1 is passed when inner to female joint 2 from the top down, and the body in electrical contact 15 of sub-joint 1 is electrically connected to 16 realizations of the body in electrical contact of female joint 2, by viscose, sub-joint 1 is fixedly connected with female joint 2 simultaneously.By the body in electrical contact that can mutually be electrically connected to is set in sub-joint 1 and female joint 2, and fix by viscose, thereby overcome in the joint loose contact problem compared with in long oil pipeline road.
Again as shown in Figure 3, be the sectional view of the first embodiment of the oil rig of this bottom fitting of application, described oil rig comprises: sub-joint 1, female joint 2, hollow rod 3, oil pipe 4, lubrication oil 5, plunger 6 and pump barrel 7.Wherein, hollow rod 3, sub-joint 1, female joint 2 and plunger 6 connect successively, and wherein hollow rod 3 is threaded connection with sub-joint 1, and female joint 2 is threaded connection with plunger 6.The bottom of oil pipe 4 connects pump barrel 7, and pump barrel 7 bottoms can connect other members such as motor (not shown).Hollow rod 3 is in oil pipe 4, and plunger 6 is in pump barrel 7.
After the oil rig of the first embodiment is arranged in well, must first lubrication oil 1 be injected in the annular space between hollow rod 3 and oil pipe 4.During oil pumping, the liquid that oil well pump is discharged enters in hollow rod 3 through sub-joint 1, thereby the liquid in pumpingh well is extracted out.The fluid density of extracting out in density ratio well due to lubrication oil 1 is little, therefore lubrication oil 1 occupies in the annular space between hollow rod 3 and oil pipe 4 all the time, thereby the lubrication of playing, reach the appearance that prevents hollow rod 3 and oil pipe 4 wear problems, because of lubrication oil non-corrosiveness, therefore the present invention has also prevented the etching problem of hollow rod 3 and oil pipe 4.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not depart from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all will falling into protection scope of the present invention.
