Description

Technical Field

[0001] The present invention relates to the technical field of oil production equipment, in particular to an oil production pump equipment, and in particular to a ground centrifugal oil production pump. Background Art

[0002] Conventional oil extraction equipment is mainly composed of downhole pumps and ground beam pumping units. Affected by geological conditions and extraction time, the oil output of many oil fields is very small in the later stage. However, in the face of the increasingly tense energy situation, it is necessary to carry out refined extraction of oil fields in the later stage, and it is necessary to extract oil fields that have been abandoned due to low oil output in the past. Conventional downhole pumps and ground beam pumping units are not competent for oil wells with small oil output. The working efficiency of the pumping units is extremely low, and the energy consumption is high, which greatly increases the development cost. The benefits are seriously disproportionate to the cost. Therefore, it is necessary to use oil extraction pumps for extraction. However, during the oil extraction process, the phenomenon of friction and deformation between the sucker rod and the pump body often occurs, which reduces the service life of the pump body.

[0003] The patent document (CN201720280952) discloses a motor-direct-driven horizontal centrifugal oil pump, comprising a motor, an impeller, a machine seal chamber, a pump body, a bracket and a base, wherein the motor is mounted at one end of the base, and the pump body is fixedly connected to the other end of the base through a bracket arranged at the bottom, and the end faces of the machine seal chamber are fixedly connected to the flange of the motor and the end face of the pump body along the axis of the motor; the impeller is mounted on the output shaft of the motor and is placed in the pump body. The appearance of the oil pump can be greatly reduced, saving the site space required for the use of the equipment, so that it is suitable for installation in narrow terrain. At the same time, due to the reduction of the transmission connection in the middle part, the vibration and noise of the oil pump are reduced, the noise pollution is reduced, the mechanical efficiency is improved, the performance parameters of the oil pump are also improved, and the application range is wider. However, the equipment has certain defects: (1) Before the oil pumping operation, the air in the pump core tube needs to be exhausted by tank liquid to keep the pump core tube in a low pressure or vacuum state. This process requires manpower and time, and the processing result is inefficient; (2) The device is provided with a base. When the device is not working, there is no protective device, which makes it easy for dust and foreign matter to accumulate on the device, increasing the difficulty of cleaning. In addition, the device is easily corroded when exposed to the outside for a long time; (3) The device does not mention the specific fixing method. The previous threaded connection is prone to rust and is difficult to rotate, which makes the disassembly and installation work inefficient. Summary of the invention

[0004] The object of the present invention is to provide a ground centrifugal oil production pump:

[0005] (1) The air in the oil production pump is vacuumed by a vacuum pump to ensure that there is no excess air in the pump casing and the pipe, thereby ensuring the oil production effect of the oil production pump. The two rotors of the vacuum pump are relatively synchronously operated by a pair of high-precision gears. The gap between the two rotors will not change due to the large torsional deformation of the driving shaft, so that the gap between the rotors can be uniform during operation. The oil production pump is vacuum treated before oil production, which can avoid the occurrence of air binding during oil production. It solves the technical problem that the pump casing and the water suction pipe must be filled with liquid before oil production, and the liquid must undergo centrifugal motion and be thrown to the outer edge of the block before oil production can be carried out, resulting in low oil production efficiency.

[0006] (2) The present invention installs a storage groove on the support base for placing the first protective plate, the second protective plate, the third protective plate and the fourth protective plate. The first protective plate, the second protective plate, the third protective plate and the fourth protective plate are pulled out of the storage groove and supported on the support base through a movable shaft and a connecting shaft, and are fixed by a first fixed handle and a second fixed handle, so as to protect and isolate the oil production equipment on the support base, thereby solving the technical problem that there is no covering and protective measures when the traditional oil production equipment is not working;

[0007] (3) The present invention uses the first fixed card block and the second fixed card block in combination, so that the second pressure cover can be moved left and right in the first fixed card block through the second fixed card block and engaged on the support seat, thereby improving the fixing and installation efficiency of the second fixed card block, facilitating the installation and disassembly of the equipment, and solving the technical problem that the previous method was only fixed by threads and was inconvenient to disassemble due to rust.

Under the action of the centrifugal force, the crude oil is discharged into the oil pipeline through the discharge pipe on the shell cover (9). After the oil production work stops, the inlet valve and the outlet valve are slowly closed, and the power supply to the first drive motor (8) is stopped.

2. A ground centrifugal oil production pump according to claim 1, characterized in that: A safety valve (10) is fixedly connected to the outer surface of the first gland (5), an inner magnetic cylinder assembly (14) is fixedly installed inside the first gland (5), a fixing frame (22) is fixedly installed on the lower surface of the first gland (5), and the first gland (5) and the fixing frame (22) are connected by threaded connection.

3. A ground centrifugal oil production pump according to claim 1, characterized in that: A pull ring (12) is fixedly mounted on the upper surface of the connecting frame (7), a first fixing bolt (18) is fixedly mounted near the middle of the connecting frame (7), a plurality of the first fixing bolts (18) are arranged side by side at equal intervals, and an isolation ring (19) is fixedly mounted near one side of the connecting frame (7).

4. A ground centrifugal oil production pump according to claim 1, characterized in that: The first drive motor (8) is movably connected to the vacuum pump (21) via a connecting pipe (20); an impeller is movably mounted in the housing (9); the impeller is provided with a plurality of blades; an outer surface of the housing (9) is movably connected to a suction pipe and a discharge pipe; the suction pipe is located on one side of the discharge pipe; an inlet valve is provided on the suction pipe; and an outlet valve is provided on the discharge pipe.

5. A ground centrifugal oil production pump according to claim 4, characterized in that: A pull block (39) is fixedly mounted on one side of the first protective plate (33), a first fixed handle (40) is fixedly mounted on the side of the pull block (39) away from the first protective plate (33), a second fixed handle (41) is fixedly mounted on one side of the support seat (1), and the pull block (39) is movably connected to the support seat (1) via the first fixed handle (40) and the second fixed handle (41).
