Description

Technical Field

[0001] This utility model relates to the field of submersible electric pumps for wells, specifically a skid-mounted submersible electric pump for wells. Background Technology

[0002] Skid-mounted submersible pumps integrate key components such as submersible pumps, motors, and control systems onto a single skid-mounted structure, forming a complete system. This design makes the entire pumping system more compact and efficient. When the motor starts, it drives the impeller of the submersible pump to rotate, thereby generating suction to pump the liquid from the well to the surface.

[0003] The pump body and motor of a submersible pump are usually connected by a connecting shaft. A screen is installed on the outside of the connecting shaft. The screen can filter the water flow entering the pump body and prevent large particles, gravel, mud or other foreign objects from entering the pump body. The liquid in the well usually acts directly on the screen, scouring it, which can easily cause blockage and damage to the screen. Therefore, a skid-mounted submersible pump for wells is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a skid-mounted submersible pump for wells to solve the problem that when the liquid downhole acts directly on the screen during the use of the skid-mounted submersible pump, it can easily cause blockage and damage to the screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A skid-mounted submersible pump for wells includes a skid frame, a pump body, a first bolt, a second bolt, and a third bolt. The pump body is mounted on the inner side of the skid frame. A connecting shaft is mounted on the bottom of the pump body, and a motor is mounted on the bottom of the connecting shaft. Evenly spaced fixing blocks are fixedly connected to the outer side of the pump body. A connecting block is detachably connected to the bottom of each fixing block via the first bolt. An arc-shaped mesh cover is fixedly connected to one side of each connecting block. An arc-shaped positioning plate is fixedly connected to the outer side of the mesh cover. Evenly spaced threaded sleeves are fixedly connected to the inner side of the arc-shaped positioning plate. An arc-shaped connecting plate is located on the outer side of the arc-shaped positioning plate. A water baffle with an inclined cross-section is fixedly connected to the bottom of the arc-shaped connecting plate. Several leakage holes are formed on the inner side of the water baffle. An electrical control cabinet is mounted on the top of the skid frame. A connecting elbow is mounted on the top of the pump body. A pressure gauge and a control valve are mounted on the outer side of the connecting elbow.

[0007] Preferably, a reinforcing block is fixedly connected to the outer side of the mesh cover, and two fitting reinforcing blocks are detachably connected by a third bolt.

[0008] Preferably, the mesh cover is disposed on the outside of the connecting shaft, and the mesh cover is disposed between the pump body and the motor.

[0009] Preferably, the threaded sleeve and the second bolt are arranged in a one-to-one correspondence, and the second bolt passes through the arc-shaped connecting plate and is threadedly connected to the threaded sleeve.

[0010] Preferably, the electrical control cabinet is electrically connected to the motor, and the pump body is connected to the connecting bend pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, a structure consisting of a mesh cover, an arc-shaped positioning plate, an arc-shaped connecting plate, a second bolt, a threaded sleeve, a water baffle, and a drain hole is used. A detachable water baffle is installed on the outside of the mesh cover through the cooperation of the arc-shaped positioning plate, the arc-shaped connecting plate, the second bolt, and the threaded sleeve. The water baffle can prevent the downhole liquid from directly impacting the mesh cover, thus protecting the mesh cover. Furthermore, impurities, gravel, silt, etc. in the downhole liquid can be discharged through the inclined drain hole in the water baffle, preventing blockage of the mesh cover. This solves the problem that when a skid-mounted submersible pump is in use, the downhole liquid directly acting on the mesh cover can easily cause blockage and damage to the mesh cover.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A skid-mounted submersible electric pump for wells includes a skid frame 1, a pump body 2, a first bolt 7, a second bolt 11, and a third bolt 16. The pump body 2 is mounted on the inner side of the skid frame 1. A connecting shaft 3 is mounted on the bottom of the pump body 2, and a motor 4 is mounted on the bottom of the connecting shaft 3. Evenly spaced fixing blocks 5 are fixedly connected to the outer side of the pump body 2. A connecting block 6 is detachably connected to the bottom of the fixing blocks 5 via the first bolt 7. An arc-shaped mesh cover 8 is fixedly connected to one side of the connecting block 6. An arc-shaped positioning plate 9 is fixedly connected to the outer side of the mesh cover 8. The inner side of the arc-shaped positioning plate 9... The side is fixedly connected with uniformly arranged threaded sleeves 12. An arc-shaped connecting plate 10 is provided on the outer side of the arc-shaped positioning plate 9. A water baffle 13 with an inclined cross section is fixedly connected to the bottom of the arc-shaped connecting plate 10. Several leakage holes 14 are opened on the inner side of the water baffle 13. An electrical control cabinet 20 is installed on the top of the skid frame 1. A connecting elbow 17 is installed on the top of the pump body 2. A pressure gauge 18 is installed on the outer side of the connecting elbow 17. A control valve 19 is installed on the outer side of the connecting elbow 17. This arrangement allows a detachable water baffle 13 to be installed on the outer side of the mesh cover 8.

[0027] A reinforcing block 15 is fixedly connected to the outer side of the mesh cover 8. Two reinforcing blocks 15 that fit together are detachably connected by a third bolt 16. This arrangement allows adjacent mesh covers 8 to be connected more stably. The mesh cover 8 is located on the outer side of the connecting shaft 3 and between the pump body 2 and the motor 4. This arrangement enables the positioning of the mesh cover 8. The threaded sleeve 12 and the second bolt 11 are arranged in a one-to-one correspondence. The second bolt 11 passes through the arc-shaped connecting plate 10 and is threadedly connected to the threaded sleeve 12. This arrangement enables the detachable installation of the arc-shaped connecting plate 10. The electrical control cabinet 20 is electrically connected to the motor 4, and the pump body 2 is connected to the connecting bend 17. This arrangement allows the electrical control cabinet 20 to control the use of the motor 4.

[0028] Workflow: All electrical appliances in this invention are equipped with an external power supply or a built-in battery. When the skid-mounted submersible pump is to be put into operation in the well, the pump body 2, connecting shaft 3, and motor 4 are installed in the preset position in the well. The connection between the pump body 2, connecting shaft 3, and motor 4 is existing technology. The skid frame 1 is positioned outside the wellhead. The motor 4 is started through the electrical control cabinet 20. The motor 4 drives the impeller in the pump body 2 to rotate through the connecting shaft 3, thereby drawing the liquid from the well into the connecting bend 17. The pressure gauge 18 can detect the hydraulic pressure in the connecting bend 17. The flow of the connecting bend 17 can be controlled through the control valve 19, thereby drawing the liquid from the well to the preset position. When the skid-mounted submersible pump is working, most of the liquid in the well will first impact the baffle plate 13. Since the baffle plate 13 is inclined, the liquid will flow along the baffle plate after impact. The fluid flows through plate 13 and is smoothly discharged through the drain hole 14. This effectively reduces the direct impact of downhole fluid on the screen 8, and greatly reduces the risk of blockage and damage to the screen 8. When the baffle plate 13 needs to be replaced, rotate the second bolt 11 to disengage it from the threaded sleeve 12 and the arc-shaped connecting plate 10, and pull the arc-shaped connecting plate 10 away from the arc-shaped positioning plate 9 to disassemble the arc-shaped connecting plate 10 and the baffle plate 13. The reverse operation can be used to install the new baffle plate 13. When the screen 8 needs to be replaced, first remove the third bolt 16 that connects the mating reinforcing block 15, then remove the first bolt 7 that connects the fixing block 5 and the connecting block 6, and finally move the screen 8 away from the fixing block 5 and the pump body 2 to disassemble the connecting block 6 and the screen 8. The reverse operation can be used to install the connecting block 6 and the screen 8.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
