The flow controller 401 is used to control the flow of gas flowing from the stamping tank 4 to the buffer tank 3. The upper part of the buffer tank 3 is connected to an oil-gas mixing solenoid valve 304 through a pipeline.

Output, the end of the oil-gas mixing solenoid valve 304 is connected to an oil-gas outlet 309, and the oil-gas outlet 309 is used to transport the mixed oil-gas mixture to the oil-gas delivery pipeline.

[0047] When using the present invention, the controller 5 controls the fluid replenishment pump 201 to start working, thereby transporting the liquid inside the liquid storage tank 2 to the buffer tank 3. At this time, the controller 5 controls the fluid replenishment pump 201 to stop working, thereby saving resource waste. At this time, the controller 5 controls the liquid control solenoid valve 305 to open and controls the second liquid control solenoid valve 306 to close. Further, the controller 5 controls the boost pump 301 to transport the liquid inside the buffer tank 3 to the jet pump 7 through a pipeline. At the same time, the controller 5 controls the oil and gas input solenoid valve 307 to open. At this time, a negative pressure is formed inside the jet pump 7, so that the oil and gas enter the jet pump 7 along the oil and gas inlet 310, and then the oil and gas are mixed. After the mixing is completed, it is further transported to the buffer tank 3. At this time, due to the different densities, The oil-gas mixture is in the upper part of the buffer tank 3.

During operation, if the liquid level detector 302 detects that the liquid content inside the buffer tank 3 is not within the preset range, the controller 5 controls the rehydration pump 201 to continue working, so as to transport the liquid inside the liquid storage tank 2 to the buffer tank 3 again. When the liquid level detector 302 detects that the liquid inside the buffer tank 3 has recovered to the preset capacity, the controller 5 controls the rehydration pump 201 to stop working again.

The suction chamber 703 is made of a lightweight material or an alloy material. A cavity is formed inside the suction chamber 703, so as to accommodate the liquid or oil and gas mixture flowing in from the oil and gas suction pipe 705. A liquid injection pipe 704 is fixed to the right part of the suction chamber 703, and the liquid injection pipe 704 can transport the liquid to the inside of the jet pump 7. A nozzle 706 is arranged inside the suction chamber 703, and the nozzle 706 adopts a funnel-shaped structure. The nozzle 706 is fixedly connected to the liquid spraying pipe 704. The nozzle 706 can pressurize the liquid flowing in from the liquid spraying pipe 704, so that a negative pressure is formed inside the suction chamber 703, so that the oil, gas and liquid can be sucked from the oil and gas suction pipe 705 into the liquid spraying pipe 704. A throat 702 is fixed on the left side of the suction chamber 703. The throat 702 is used to mix the oil and gas flowing in from the oil and gas suction pipe 705. A diffuser 701 is fixed on the left side of the throat 702. The diffuser 701 adopts a funnel-shaped structure. 701 is used to re-pressurize the oil-gas mixture flowing out of the throat pipe 702.

The left side of each clamping ring telescopic rod 645 is fixed A clamping ring telescopic controller 646 is provided, and the clamping ring telescopic controller 646 is used to control the expansion and contraction of the clamping ring telescopic rod 645, so that the inner diameters of the two clamping rings 604 change, so that the clamping ring 604 can adapt to the jet pumps 7 of different diameters, and can clamp or loosen the jet pump 7 at the same time. A clamping ring moving controller 644 is fixed on the upper part of each clamping ring moving rod 643, and the clamping ring moving controller 644 can control the expansion and contraction of the clamping ring moving rod 643, so as to control the distance between the two clamping rings 604;

[0049] When using the present invention, when the oil and gas flow rate in the transmission pipeline is lower than the flow rate interval preset by the flow meter 308, the controller 5 controls the oil and gas mixing solenoid valve 304 and the liquid control solenoid valve 305 to close, so that the oil and gas are no longer transported. At this time, the pressure sensor 303 returns the monitoring data to the controller 5. If the pressure sensor 303 detects that the internal pressure of the buffer tank 3 is lower than the preset interval, the controller 5 controls the flow controller 401 to start working, so as to pressurize the buffer tank 3. When the pressure is increased to the preset interval, the controller 5 controls the flow controller 401 to stop working. At this time, the pressure sensor 303 continues to work. When the pressure sensor 303 is found to have obvious changes in the data of the pressure sensor 303 after working for a period of time, it proves that the buffer tank 3 is If there is a leak in the buffer tank 3, the controller 5 will sound an alarm so that the staff can inspect the buffer tank 3. If after the flow controller 401 stops working, the buffer tank 3 detects that the internal pressure of the buffer tank 3 remains within the preset range, the controller 5 controls the boost pump 301, the liquid control solenoid valve 305 and the second liquid control solenoid valve 306 to start working, and at the same time controls the oil and gas input solenoid valve 307 to close, so that the liquid enters the jet pump 7. If the flow meter 308 shows that the flow rate is within the preset range at this time, it proves that the oil and gas input pipeline or the oil and gas outlet 309 is blocked. At this time, the staff can inspect the relevant pipeline or the oil and gas outlet 309. If the flow meter 308 shows that the flow rate is still not within the preset range at this time, it proves that the jet pump 7 is damaged.

When the sleeve 636 moves to above the bolt on the flange of the jet pump 7, the controller 5 controls the sleeve telescopic controller 634 to stop working. At this time, the controller 5 controls the disassembly rotating ring telescopic controller 651 to start working, so that The disassembly rotating ring telescopic rod 605 contracts, so that the multiple sleeves 636 are close to the outer surface of the flange of the jet pump 7, so that the bolts on the flange of the jet pump 7 are clamped by the sleeves 636. At this time, the controller 5 controls the sleeve rotation motor 635 to start working, so that the sleeve 636 rotates, so that the bolts on the flange of the jet pump 7 are unscrewed. At this time, the controller 5 controls the disassembly rotating ring telescopic controller 651 to work in reverse, so that the two disassembly mechanisms 603 move away. At this time, the controller 5 controls the two clamping ring movement controllers 644 to work in reverse, so that the two clamping ring movement rods 643 contract, so that the damaged jet pump 7 is removed.At this time, the controller 5 controls the clamping ring rotating motor 642 to start working, so that the clamping ring rotating disk 641 rotates, thereby rotating the jet pump 7. After the jet pump 7 rotates half a circle around the clamping ring rotating disk 641, the controller 5 controls the clamping ring rotating motor 642 to stop working. At this time, the controller 5 controls the two clamping ring moving controllers 644 to work, so that the clamping ring moving rod 643 extends, so that the new jet pump 7 reaches the required position. At this time, the controller 5 controls the sleeve 636 to work in the reverse direction, so that the new jet pump 7 is installed. At this time, the controller 5 controls the disassembly mechanism vertical telescopic rod 601 and the disassembly mechanism horizontal telescopic rod 602 to work in the reverse direction, so that the disassembly mechanism 603 returns to the original position. At this time, the controller 5 controls the clamping ring 604 to return to the original position.

[0052] The working process of the present invention is as follows: when using the present invention, the controller 5 controls the fluid replenishment pump 201 to start working, thereby transporting the liquid inside the liquid storage tank 2 to the buffer tank 3. At this time, the controller 5 controls the fluid replenishment pump 201 to stop working, thereby saving resource waste. At this time, the controller 5 controls the liquid control solenoid valve 305 to open and controls the second liquid control solenoid valve 306 to close. Further, the controller 5 controls the boosting pump 301 to transport the liquid inside the buffer tank 3 to the jet pump 7 through a pipeline. At the same time, the controller 5 controls the oil and gas input solenoid valve 307 to open. At this time, a negative pressure is formed inside the jet pump 7, so that the oil and gas enter the jet pump along the oil and gas inlet 310. 7, and then the oil and gas are mixed. When the mixing is completed, it is further transported to the buffer tank 3. At this time, due to the difference in density, the oil and gas mixture is in the upper part of the buffer tank 3. Due to the pressurization of the jet pump 7, the oil and gas mixture inside the jet pump 7 follows the pipeline to the oil and gas mixing solenoid valve 304. At this time, the controller 5 controls the oil and gas mixing solenoid valve 304 to open, so that the oil and gas mixture reaches the oil and gas outlet 309, and then enters the oil and gas transmission pipeline along the oil and gas outlet 309. During the working process, if the liquid level detector 302 detects that the liquid content inside the buffer tank 3 is not within the preset range, the controller 5 controls the liquid replenishment pump 201 to continue working, so as to fill the storage tank 3 with liquid again. The liquid inside the liquid tank 2 is transported to the inside of the buffer tank 3. When the liquid level detector 302 detects that the liquid inside the buffer tank 3 has recovered to the preset capacity, the controller 5 controls the liquid replenishing pump 201 to stop working again. When using the present invention, when the oil and gas flow rate in the transmission pipeline is lower than the flow rate interval preset by the flow meter 308, the controller 5 controls the oil and gas mixing solenoid valve 304 and the liquid control solenoid valve 305 to close, so that the oil and gas are no longer transported. At this time, the pressure sensor 303 returns the monitoring data to the controller 5. If the pressure sensor 303 detects that the internal pressure of the buffer tank 3 is lower than the preset interval, the controller 5 controls the flow controller 401 to start working, thereby filling the buffer tank 3. When the pressure is increased to a preset range, the controller 5 controls the flow controller 401 to stop working. At this time, the pressure sensor 303 continues to work. When the pressure sensor 303 is found to have obvious changes in the data of the pressure sensor 303 after working for a period of time, it proves that the buffer tank 3 is leaking. At this time, the controller 5 issues an alarm so that the staff can inspect the buffer tank 3. If, after the flow controller 401 stops working, the buffer tank 3 monitors that the internal pressure of the buffer tank 3 remains within the preset range, the controller 5 controls the boost pump 301, the liquid control solenoid valve 305 and the second liquid control solenoid valve 306 to start working, and at the same time controls the oil and gas input solenoid valve 307 to be closed.Thereby, the liquid enters the jet pump 7. If the flow meter 308 shows that the flow rate is within the preset range at this time, it proves that the oil and gas input pipeline or the oil and gas outlet 309 is blocked. At this time, the staff can repair the relevant pipeline or the oil and gas outlet 309. If the flow meter 308 shows that the flow rate is still not within the preset range at this time, it proves that the jet pump 7 is damaged. At this time, the controller 5 controls the rear clamping ring movement controller 644 to work, so that the rear clamping ring movement rod 643 is extended, so that the rear clamping ring 604 is close to the jet pump 7. At this time, the controller 5 controls the rear clamping ring telescopic controller 646 to start working, so that the rear clamping ring telescopic rod 645 is extended. Thereby, the two clamping rings 604 at the rear side move away from each other. At this time, the controller 5 controls the clamping ring moving rod 643 at the rear side to extend again. When the clamping ring 604 at the rear side and the throat 702 are on the same vertical line, the controller 5 controls the clamping ring moving controller 644 at the rear side to stop working. At this time, the controller 5 controls the clamping ring telescopic controller 646 at the rear side to work in the opposite direction, so that the two clamping ring telescopic rods 645 at the rear side shrink, so that the two clamping rings 604 at the rear side fit tightly with the damaged throat 702, so that the clamping ring 604 at the rear side clamps the damaged jet pump 7. At this time, the controller 5 controls the disassembly mechanism vertical telescopic controller 611 to start working. Thereby, the vertical telescopic rod 601 of the disassembly mechanism is extended, so that the disassembly mechanism 603 moves upward. When the disassembly mechanism 603 moves to the height of the flange of the jet pump 7, the controller 5 controls the vertical telescopic controller 611 of the disassembly mechanism to stop working, and at the same time controls the lateral telescopic controller 621 of the disassembly mechanism to start working, so that the lateral telescopic rod 602 of the disassembly mechanism is extended, so that the disassembly mechanism 603 moves horizontally. When the disassembly mechanism 603 is parallel to the flange of the jet pump 7, the controller 5 controls the lateral telescopic controller 621 of the disassembly mechanism to stop working. At this time, the controller 5 controls the sleeve telescopic controller 634 to start working, so that the sleeve The telescopic rod 633 begins to telescope, thereby causing the sleeve 636 to begin to move. When the sleeve 636 moves to above the bolts on the flange of the jet pump 7, the controller 5 controls the sleeve telescopic controller 634 to stop working. At this time, the controller 5 controls the disassembly rotating ring telescopic controller 651 to start working, thereby causing the disassembly rotating ring telescopic rod 605 to shrink, thereby causing the plurality of sleeves 636 to cling to the outer surface of the flange of the jet pump 7, thereby causing the bolts on the flange of the jet pump 7 to be clamped by the sleeve 636. At this time, the controller 5 controls the sleeve rotation motor 635 to start working, thereby causing the sleeve 636 to rotate, thereby causing the bolts on the flange of the jet pump 7 to be unscrewed.At this time, the controller 5 controls the disassembly rotating ring telescopic controller 651 to work in reverse, so that the two disassembly mechanisms 603 move away from each other. At this time, the controller 5 controls the two clamping ring moving controllers 644 to work in reverse, so that the two clamping ring moving rods 643 shrink, so that the damaged jet pump 7 is removed. At this time, the controller 5 controls the clamping ring rotating motor 642 to start working, so that the clamping ring rotating disk 641 rotates, thereby rotating the jet pump 7. When the jet pump 7 rotates half a circle around the clamping ring rotating disk 641, the controller 5 controls the The clamping ring rotating motor 642 stops working, and the controller 5 controls the two clamping ring moving controllers 644 to work, so that the clamping ring moving rod 643 is extended, so that the new jet pump 7 reaches the desired position, and the controller 5 controls the sleeve 636 to work in the reverse direction, so that the new jet pump 7 is installed, and the controller 5 controls the disassembly mechanism vertical telescopic rod 601 and the disassembly mechanism horizontal telescopic rod 602 to work in the reverse direction, so that the disassembly mechanism 603 returns to the original position, and the controller 5 controls the clamping ring 604 to return to the original position.
