Description

FIG. Figure 1 shows a general view of single plants or groups equipped with each of their 1M engines and a common feed pipe with connections, fig. 2 shows the drive from one engine to several pumps; FIG. 3 is a view and a longitudinal section of the cylinder and in FIG. 4, 5 and 6 are indicated in positions I. Both the III and the combinations that can be produced by transferring a four-way valve / 5 from the middle of the hand (the feed line is indicated by two solid lines, a dotted line with a dash-back line, and points in atmosphere and solid single- communicated with the intertube well space-).

The proposed sucker-rod pump for pumping oil from boreholes drives it with a one-way steam or air engine or water engine. The cylinder / engine consists of an ordinary gas pipe and is closed on both sides with covers 2, of which the bottom is provided with an epiploon, and the top - with a drain in the center; the covers are provided with holes for hanging the cylinder. Inside the cylinder, the piston 3 moves with cast-iron rings or leather cuffs 4, depending on whether the engine is running with steam, air or water. The piston is tightly mounted on the hollow rod 5. which is plugged in the upper part and has an opening 6 near the piston for inlet and outlet of working steam, air or liquid. A three-way valve 7 with a handle 20, moved during the piston stroke by an S, attached to the cylinder cTeHJie in the upper part, and a clip 8, is screwed onto the lower end of the rod. Nozzle 9, replacing the mounting collars, is abutted casing 70, keeps the pump pipe string 7 / in the vent position and at the same time creates a hermetically sealed inter tubing space in the well 72. The rubber hose 7J communicates the cylinder with compressed air, steam, etc .; a hose 75 connects with a crane to the annulus of the well with the atmosphere or the return line.

Hai of the end of the three-way crane freely rotates the swivel 16 with a tapered thread for tightening the rod 77 and cutting along the periphery corresponding to the cutting of pump tubes; in the upper part of the swivel there is a counter-nut or stud ;, to eliminate the rotation of the swivel. Inside the cylinder on the upper kryinka lies a buffer ring.

When installing the crane 7 to the inlet position, (B) air enters the cylinder, pushes the piston, which requires a high-pressure axle system (rods, plunger, etc.); when the valve 7 is positioned on the outlet, the air, the outlet from the cylinder, is directed to the valve 18, through which it is discharged at discretion. Blown out by the bi-tube space, it will generate pressure on

fluid in the well, raising its level under the pump suction valve, and this makes it possible to set the suction valve higher to the outlet and, thus, shorten the string of pipes and rods and even cause spouting (with shallow fluid levels and abundance of gases).
