Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic control systems, in particular to compact intelligent hydraulic oil pumping station equipment. Background Art

[0002] At present, the equipment used in the oil extraction industry to extract oil is changing from the original oil beam pumping unit to the safer and more convenient intelligent hydraulic pumping unit. As the core of the intelligent hydraulic pumping unit, the hydraulic pump station equipment has emerged.

[0003] Most current hydraulic pump stations utilize a three-phase asynchronous variable-frequency motor as a bidirectional power source. The motor-pump unit is connected to the valve block and oil tank via hoses. To meet the torque requirements of large loads, the number of motor-pump units required increases. Furthermore, to minimize the impact of vibration generated by the motor-pump unit on other components of the hydraulic pump station, the motor-pump unit must be installed at the bottom of the hydraulic pump station structure. This increases the overall size of the hydraulic pump station, hindering its adjustment and movement at the worksite. Furthermore, since the motor-pump unit is located at the very bottom of the hydraulic pump station structure, it wastes internal space above the hydraulic pump station, making repair, replacement, and maintenance more difficult.

[0004] Therefore, there is an urgent need for a compact intelligent hydraulic oil pumping station equipment with small size, compact structure, and easy maintenance and operation to solve the various drawbacks of existing hydraulic pumping stations. Summary of the Invention

[0005] This patent proposes a new type of intelligent hydraulic pumping unit pump station equipment, which mainly solves the technical problems of existing intelligent hydraulic pumping unit hydraulic pump station equipment such as large size, difficulty in transportation, and difficulty in repair and maintenance.

[0007] The working principle of the compact intelligent hydraulic pumping station equipment provided by this patent:

[0008] First, the auxiliary support frame 11, as the main supporting component of the compact intelligent hydraulic pumping unit pump station equipment, is firmly installed on the internal base bracket of the hydraulic pump station through M16 hexagon socket bolts, lifting the compact intelligent hydraulic pumping unit pump station equipment to a height of 500mm. The valve block 8, as the core component of the equipment, is installed on the upper end of the auxiliary support frame 11 using M12 hexagon socket bolts. The main oil circuit bell cover 2 and the oil supply circuit bell cover 5 serve as the connecting components of the main oil circuit motor pump group and the oil supply motor pump group and the valve block 8. They are installed on the axial end face and lateral end face of the valve block 8 in a special positioning method, supporting and fixing the main oil circuit servo motor 1, the main oil circuit hydraulic plunger motor 10, the oil supply circuit servo motor 3, and the oil supply circuit gear pump 7. The auxiliary oil circuit pipe 9 adopts a DN32 diameter seamless steel pipe. While connecting the system oil circuit, it also plays a certain supporting role for the motor pump groups suspended on both sides. The structure of this patented design completely uses hard connection, the length of the connecting pipeline is small, the structure is stable and strong, the oil circuit pressure loss is small, and the internal idle space of the hydraulic pump station is effectively utilized, fundamentally reducing the overall volume of the hydraulic pump station.

[0009] Beneficial technical effects of the utility model:

[0011] 2.

[0012] 3. Due to the use of a small and high-power servo motor, the overall volume and weight of the hydraulic pump station are reduced while meeting the rated working requirements, making it easier for the hydraulic pump station to change wells or adjust the installation position according to actual working conditions at the oil production site;

[0013] 4. The suspended installation method of the motor pump unit makes all the parts of the motor pump unit exposed to the outside without any obstruction or interference, which greatly facilitates the repair, replacement and maintenance of the motor pump unit by on-site personnel.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] A compact intelligent hydraulic pumping station equipment, including a main oil circuit servo motor 1, a main oil circuit bell 2, an oil supply circuit servo motor 3, a main oil circuit coupling 4, an oil supply circuit bell 5, an oil supply circuit coupling 6, an oil supply circuit gear pump 7, a valve block 8, an auxiliary oil circuit pipe 9, a main oil circuit hydraulic piston motor 10, and an auxiliary support frame 11, wherein: the valve block 8 is mounted on the auxiliary support frame 11 through a hexagon socket bolt, the main oil circuit bell 2 is mounted in the axial direction of the valve block 8 through a hexagon socket bolt, the oil supply circuit bell 5 is mounted in the lateral direction of the valve block 8 through a hexagon socket bolt, the main oil circuit servo motor 1 and the main oil circuit hydraulic piston motor 10 are connected through the main oil circuit coupling 4, and the main oil circuit coupling 4 is placed on the main oil circuit bell hood. 2, the main oil circuit servo motor 1 is installed on the upper end of the main oil circuit bell 2 with a hexagon socket bolt, and the main oil circuit hydraulic plunger motor 10 is installed on the lower end of the main oil circuit bell 2 with a hexagon socket bolt. The oil supply circuit servo motor 3 and the oil supply circuit gear pump 7 are connected through the oil supply circuit coupling 6. The oil supply circuit coupling 6 is placed inside the oil supply circuit bell 5. The oil supply circuit servo motor 3 is installed on the upper end of the oil supply circuit bell 5 with a hexagon socket bolt, and the oil supply circuit gear pump 7 is installed on the lower end of the oil supply circuit bell 5 with a hexagon socket bolt. The main oil circuit hydraulic plunger motor 10 is connected to the two oil inlets of the valve block 8 through the auxiliary oil circuit pipe 9, and the oil supply circuit gear pump 7 is connected to the oil supply inlet of the valve block 8 through the auxiliary oil circuit pipe 9.

[0020] Before work, the equipment structure is installed inside the hydraulic pump station through the auxiliary support frame 11 to form a hydraulic pump station system. And ensure that the distance between the bottom end of the main oil circuit hydraulic piston motor 10 and the installation base of the hydraulic pump station equipment is within the range of 180 mm to 220 mm.

[0021] After the preparatory work is completed, the main oil circuit hydraulic piston motor 10 is connected to the two oil inlets of the valve block 8 through the auxiliary oil circuit pipe 9. The high-pressure ball valve installed on the auxiliary oil circuit pipe 9 is opened to connect the equipment oil circuit with the oil circuit of the external oil cylinder connected to the two oil inlets of the valve block 8. The oil supply circuit servo motor 3 is turned on. The oil supply circuit servo motor 3 is connected to the oil supply circuit gear pump 7 through the oil supply circuit coupling 6. The oil supply circuit gear pump 7 starts to simultaneously inject hydraulic oil into the two oil cylinders connected to the outside of the equipment. When the oil injection volume reaches the set value, the oil supply circuit gear pump 7 stops. At the same time, the main oil circuit servo motor 1 starts according to the settings of the preset control program, extracting the hydraulic oil from the oil cylinder on one side and injecting it into the oil cylinder on the other side. At this time, the piston of the oil cylinder on the side being pumped oil descends, and the piston of the oil cylinder on the side being injected oil rises. When the piston of the oil cylinder on the rising side rises to the height set by the program, the sensor on the oil cylinder transmits the arrival signal to the PLC control system. The control system controls the main oil circuit servo motor 1 to reverse, and the main oil circuit motor pump group reversely extracts the hydraulic oil in the oil cylinder on the rising side and injects it into the oil cylinder on the descending side. The oil cylinder piston on the descending side rises due to the injection of hydraulic oil, and the oil cylinder piston on the rising side falls due to the extraction of hydraulic oil, until the sensor starts again to transmit the arrival signal to the PLC control system, and the PLC control system controls the main oil circuit servo motor 1 to reverse again, and repeats this process to form a working cycle.

[0022] Compared with the original motor pump group installation method, the auxiliary oil circuit pipe 9 is one-third shorter than the original hose connection method. According to the principle that the shorter the pipeline length is, the smaller the pressure loss in the pipeline is when the diameter is the same, the auxiliary oil circuit pipe 9 of this patent reduces the pressure loss by one-third compared with the original hose connection method, thereby effectively improving the efficiency of the hydraulic system.

[0023] If the main oil circuit motor or pump unit of the equipment needs to be repaired or replaced, it is only necessary to open the door panel on the side of the main oil circuit servo motor 1 and remove the inner hexagonal mounting bolts connecting the main oil circuit servo motor 1 and the main oil circuit bell cover 2, or the inner hexagonal mounting bolts connecting the main oil circuit hydraulic plunger motor 10 and the main oil circuit bell cover 2. Then, the main oil circuit servo motor 1 or the main oil circuit hydraulic plunger motor 10 can be easily moved. Repair or replacement of the oil circuit motor pump unit follows the same procedure.
