Abstract
The name of the utility model is a separate surface drive device for body screw rod oil pump belonging to surface drive device for screw rod for oil product in oil fields. The device consists of an upper body 1, a lower body 2, a screw bolt 3, and an O ring 4. The screw bolt 3 is used to integrate the upper body 1 and the lower body 2 for different matching so as to satisfy different requirements of users. The two bodies can be separated with the use of some simple tools, making simpler and easier for overhaul, maintenance, and assembling. Different functions and matches are available in order to suit the on-site requirements. The utility model is simple structure and easy operation which saves labor, time, and costs. The device will ensure the long life of the equipment and shortens the time of breakdown for maintenance.
Description
Technical field
The utility model is a kind of split type progressive cavity pump surface drive that uses progressive cavity pump to recover the oil in the using process of oil field.
Background technique
Use split type progressive cavity pump surface drive can satisfy different well ' s conditions, different ground condition when extracting oil well down-hole liquid, different maintenance means need be carried out various combination.
Summary of the invention
The purpose of this utility model is that designed split type progressive cavity pump surface drive can make its upper and lower body can carry out different assembly, is more convenient for satisfying user's different demands.By using some simple tools that upper and lower body is separated, make maintenance, safeguard that assembling is simple more, convenient.Function and combination for different upper and lower bodies make it more can adapt to on-the-spot needs.Simple in structure, easy to operate, saving of labor, save time, province's expense, but the long lifetime of support equipment use, shortened fault power time greatly.
The utility model achieves the goal by following technical solution:
Split type progressive cavity pump surface drive, it is made up of upper body (1), lower body (2), bolt (3) and O type circle (4) etc., it is characterized in that upper body (1) is divided into three parts, and the one, left end mechanical transmission input part; The 2nd, the sealing and the transmission output of upper end; The 3rd, the part that the lower end is connected with lower body (2).Lower body (2) is divided into upper, middle, and lower part; Top is the part that is connected with upper body (1); The bottom is the part that is connected or connects other difference in functionality lower bodies (2) with the oil recovery well wellhead flange; The middle part is the adapter mouth that is connected with petroleum pipeline, or the adapter mouth that is connected with the clamp holder that polished rod or hollow polished rod are housed simultaneously, preventer etc.; Bolt (3) is to connect upper body (1) and lower body (2) all-in-one-piece.O type circle (4) is installed in upper body (1) and lower body (2) inner chamber junction point, can prevent that the pressure liquid of lower body (2) inner chamber from rushing down outward.
The utility model also achieves the goal by following technical solution: the top shrinkage pool of the convex shoulder below upper body (1) and lower body (2) has preferably and cooperates, the center of upper body (1) and the center of lower body (2) are consistent substantially, thus reach with well head to the center.
The beneficial effects of the utility model are:
By using some simple tools that upper and lower body is separated, make maintenance, safeguard that assembling is simple more, convenient.Function and combination for different upper and lower bodies make it more can adapt to on-the-spot needs.Simple in structure, easy to operate, saving of labor, save time, province's expense, but the long lifetime of support equipment use, shortened fault power time greatly.
It is identical that the utility model and other progressive cavity pump surface drives are connected with production wellhead, petroleum pipeline, installs identical, convenient.
Description of drawings
Accompanying drawing is structural representation of the present utility model.Wherein (1) is the upper body, and (2) are lower body, and (3) are bolt, and (4) are O type circle.
Embodiment
The utility model is: split type progressive cavity pump surface drive, upper body (1) is mechanical transmission and upper end sealing and transmission output, the lower end connects fastening lower body (2) by bolt (3), the top shrinkage pool of convex shoulder below the upper body (1) and lower body (2) has and cooperates the center that can make upper body (1) and the center of lower body (2) to be consistent substantially preferably, and O type circle (4) prevents that the pressure liquid of lower body (2) inner chamber from leaking.
Claims (3)
1. split type progressive cavity pump surface drive, it is made up of upper body (1), lower body (2), bolt (3) and O type circle (4), it is characterized in that upper body (1) is divided into three parts, and the one, left end mechanical transmission input part; The 2nd, the sealing and the transmission output of upper end; The 3rd, the part that the lower end is connected with lower body (2).
2. split type progressive cavity pump surface drive according to claim 1 is characterized in that: lower body (2) is divided into upper, middle, and lower part; Top is the part that is connected with upper body (1); The bottom is the part that is connected or connects other difference in functionality lower bodies (2) with the oil recovery well wellhead flange; The middle part is the adapter mouth that is connected with petroleum pipeline, or the adapter mouth that is connected with the clamp holder that polished rod or hollow polished rod are housed simultaneously, preventer etc.; Bolt (3) is to connect upper body (1) and lower body (2) all-in-one-piece.
