Description

Technical Field

[0001] The present invention relates to the field of pump station technology, and more specifically, to a fracturing pump station. Background Technology

[0002] Reciprocating plunger pump stations are an indispensable type of industrial pump. Their outstanding features are: high discharge pressure, flow rate independent of pressure, wide applicability to various media, good suction performance, high efficiency, and performance that does not change with pressure or viscosity of the transported medium. In today's world of energy shortages, reciprocating pump stations, as energy-saving products, play an important role in coal mining, underground fracturing, oil extraction, pipeline coal transportation, coal gasification, power plant slag removal, and mining.

[0003] A fracturing pump station is a device that converts electrical energy or other energy sources into mechanical energy, which is then used internally to work on the fracturing fluid, thereby converting it into hydraulic energy. Fracturing pump stations are suitable for pumping various non-corrosive, non-viscous or viscous liquids (such as water, crude oil, acid, mud, and sand), and are commonly used in coal mine fracturing, roof and floor perforation for cavity removal and outburst mitigation, coal seam water injection, pipeline applications, and fluid dynamics operations with adjustable pressure and flow rates. Fracturing pump stations can operate as single units or in combination with multiple units. The working principle of a fracturing pump relies on the rotation of a crankshaft to drive a plunger in reciprocating motion, achieving fluid intake and discharge.

[0004] Existing fracturing pump stations, whether using hydraulic transmissions or variable frequency motors, suffer from excessive overall height, hindering transport, especially in mines with ventilation doors. Transporting the equipment requires a minimum width of 1.4m and a minimum height of 1.8m. When these requirements are not met, the equipment must be disassembled, lowered into the mine, transported, and then reassembled and tested at a designated location underground, adding unnecessary preparation time. Furthermore, existing fracturing pump cooling systems suffer from poor integration and disorganized cooling pipes, easily leading to poor heat dissipation in certain areas and causing customers to spend considerable time on connecting the cooling pipes. Summary of the Invention

[0005] To address the problems of excessive height and low integration of cooling systems in existing technologies, embodiments of the present invention provide a fracturing pump station.

[0006] In view of this, the present invention discloses a fracturing pump station base, including a base frame assembly, a fracturing pump mounting seat on the base frame assembly, and a recessed hollow structure for installing a lubrication and cooling system on the base frame assembly, the recessed hollow structure being located below the fracturing pump mounting seat.

[0007] In some embodiments, the lubrication and cooling system includes a lubricating oil tank and a lubricating oil cooler, and the recessed hollow structure is provided with a lubricating oil tank mounting position and a lubricating oil cooler mounting base.

[0008] In some embodiments, the underframe assembly includes a first longitudinal beam, a second longitudinal beam, and a base plate, with both sides of the base plate connected to the lower parts of the first longitudinal beam and the second longitudinal beam, respectively, to form the recessed hollow structure.

[0009] In some embodiments, the lower surface of the base plate is connected to the first longitudinal beam and the second longitudinal beam.

[0010] In some embodiments, the system further includes a front beam, a rear beam, and a first crossbeam. The front beam is located in front of the rear beam, and its two ends are connected to the first longitudinal beam and the second longitudinal beam, respectively. The two ends of the first crossbeam are connected to the first longitudinal beam and the second longitudinal beam, respectively. The two ends of the rear beam are connected to the first crossbeam and the first longitudinal beam, respectively. The fracturing pump mounting base is disposed on the front beam and the rear beam. The fracturing pump mounting base includes a crankcase assembly mounting base and a hydraulic end assembly mounting base.

[0011] In some embodiments, both the front beam and the rear beam are arched structures, which provides more installation space.

[0012] In some embodiments, a second crossbeam and a torsion plate are also included, the edge of the torsion plate being connected to the first crossbeam, the first longitudinal beam, the second crossbeam, and the first longitudinal beam, and the torsion plate being provided with a coupling cover mounting position.

[0013] In some embodiments, a third crossbeam is also included, and the second crossbeam and the third crossbeam are provided with variable frequency motor mounting brackets.

[0014] In some embodiments, the lubricating oil tank mounting position and the lubricating oil cooler mounting base are arranged along the length of the base assembly.

[0015] In some embodiments, a centralized cooling system is further included, comprising a first centralized cooling valve and a second centralized cooling valve. A water tank is connected to the inlet of the first centralized cooling valve via a main pipe, and the outlet of the first centralized cooling valve is connected to a first inlet pipe and a second inlet pipe, respectively. The first inlet pipe is connected to the inlet of a lubricating oil cooler, and the outlet of the lubricating oil cooler is connected to the water tank. The outlet of the second inlet pipe is connected to the inlet of the variable frequency motor and the inlet of the variable frequency drive, respectively. The outlets of the variable frequency motor and the variable frequency drive are both connected to the water tank via return water pipes.

[0016] This disclosure has the following beneficial effects:

[0017] The base assembly provided in this disclosure features a recessed hollow structure, within which the lubricating oil tank and lubricating oil cooler are installed, effectively reducing the overall height of the pump station. Through the design of torsion plates and reinforcing ribs, the pump station base possesses sufficient strength and rigidity, significantly simplifying the pump station base design and resulting in substantial weight reduction compared to conventional fracturing pump stations.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this disclosure provides a fracturing pump station, including a base frame assembly 900, which is the mounting foundation of the fracturing pump station. A crankcase assembly 100, a variable frequency motor 300, a hydraulic end assembly 200, a lubrication and cooling system, a centralized cooling system 800, and lubrication components, etc., are mounted on the base frame assembly 900.

[0040] To reduce the overall height of the fracturing pump station, the base assembly 900 includes a recessed hollow structure 911. A lubrication and cooling system is installed in the recessed hollow structure 911, comprising a lubricating oil tank 700 and a lubricating oil cooler 600. This avoids the situation where the lubricating oil tank 700 is placed on top of a conventional pump station base, resulting in an excessively high overall height of the pump station. This allows the pump station to pass smoothly through the coal mine ventilation doors, avoiding the unnecessary preparation time required for construction, which necessitates disassembling the pump station, transporting it underground, and then reassembling and debugging it at a designated location underground, as is common in existing technologies.

[0041] The base assembly 900 is equipped with a fracturing pump mounting base 910, a variable frequency motor mounting base 920, a lubricating oil cooler mounting base 930, a lubricating motor assembly mounting base 940, and a centralized cooling system mounting base. The centralized cooling system mounting base includes a first centralized cooling valve mounting base 950 and a second centralized cooling valve mounting base 960. The fracturing pump mounting base 910 is used to mount the crankshaft assembly and the hydraulic end assembly 200. The lubricating motor assembly mounting base 940 is used to mount the lubricating motor assembly, which is used for lubrication of the pump station. It adopts an external arrangement, which is more convenient and flexible for disassembly and maintenance compared to an internal arrangement. At the same time, the base assembly 900 is also equipped with a lubricating oil tank mounting position 970, a coupling cover mounting position 980, and a cooling water pipe mounting hole 990. The cooling water pipe mounting hole 990 is specifically a slotted hole, which facilitates the installation of cooling pipes 890.

[0042] Specifically, such as Figure 5 , Figure 6 and Figure 7As shown, the base frame assembly 900 includes a first longitudinal beam 901, a second longitudinal beam 902, a first crossbeam 903, a second crossbeam 904, a reinforcing beam 907, and a third crossbeam 905. Both ends of the first crossbeam 903, the second crossbeam 904, the reinforcing beam 907, and the third crossbeam 905 are connected to the first longitudinal beam 901 and the second longitudinal beam 902. The first longitudinal beam 901 is provided with a first centralized cooling valve mounting seat 950 and a second centralized cooling valve mounting seat 960. The front end of the first crossbeam 903 is provided with... A base plate 906 is provided, with its two ends connected to the first longitudinal beam 901 and the second longitudinal beam 902, respectively. A lubrication motor assembly mounting base 940 is provided on the base plate 906 near the front end of the base frame assembly 900. A front beam 908 is provided above the base plate 906, with its two ends connected to the first longitudinal beam 901 and the second longitudinal beam 902, respectively. A rear beam 909 is provided on the first crossbeam 903. The rear beam 909, the base plate 906, and the front beam 908 form a [missing information - likely a structural element]. The recessed hollow structure 911 is formed, and a lubricating oil tank mounting position 970 and a lubricating oil cooler mounting seat 930 are provided in the recessed hollow structure 911. This arrangement can reduce the occupation of height space and allow the pump station to pass through the damper smoothly. Furthermore, the two ends of the rear beam 909 are respectively connected to the first longitudinal beam 901 and the first transverse beam 903. The front beam 908 and the rear beam 909 are provided with fracturing pump mounting seats 910 for mounting the crankcase assembly 100 and the hydraulic end assembly 200. The bottom The lubricating oil tank mounting position 970 is provided on the plate 906 and the second longitudinal beam 902 for installing the lubricating oil tank 700. Since this position is lower than the upper surface of the first longitudinal beam 901 and the second longitudinal beam 902, installing the lubricating oil tank 700 here can reduce the overall height of the pump station and allow the pump station to pass smoothly through the coal mine ventilation door. The base plate 906 is provided with a lubricating oil cooler mounting seat 930. The lubricating oil cooler 600 is installed below the crankcase assembly 100 to reduce the occupation of height space.

[0043] Furthermore, to improve the overall rigidity and strength of the pump station, a torsion plate 912 is provided between the first crossbeam 903 and the second crossbeam 904. The edge of the torsion plate 912 is connected to the upper part of the first crossbeam 903, the upper part of the first longitudinal beam 901, the upper part of the second crossbeam 904, and the upper part of the second longitudinal beam 902, respectively. The torsion plate 912 is provided with a coupling 500 cover mounting position. Specifically, the torsion plate 912 has a coupling 500 cover mounting hole. A reinforcing rib 913 is connected below the torsion plate 912. The reinforcing rib 913 is "X" shaped. The end of the reinforcing rib 913 is connected to the first longitudinal beam 901 and the second longitudinal beam 902. The first crossbeam 903, the first longitudinal beam 901, the second crossbeam 904 and the second longitudinal beam 902 are reinforced by the torsion plate 912 and the reinforcing rib 913 located in the middle to obtain sufficient torsional stiffness. This ensures that the fracturing pump station base frame assembly 900 has sufficient strength and stiffness when the variable frequency motor 300 is connected to the gearbox 400 through the coupling 500 to transmit torque. It also ensures the coaxiality of the variable frequency motor shaft and the fracturing pump input shaft, thereby ensuring the normal wear of the elastic body of the coupling 500 and achieving the expected service life.

[0044] Specifically, the second crossbeam 904 and the third crossbeam 905 are provided with variable frequency motor mounting bases 920. The outer side of the variable frequency motor mounting base 920 is provided with four centering adjustment supports 921. The centering adjustment supports 921 are connected to the base of the variable frequency motor 300 by the top of the bolts. By rotating the bolts, the variable frequency motor 300 is pushed to move laterally, so that the output shaft of the variable frequency motor 300 is aligned with the coupling 500.

[0045] More specifically, in this embodiment, the first longitudinal beam 901, the second longitudinal beam 902, the first crossbeam 903, the second crossbeam 904, the reinforcing beam 907, and the third crossbeam 905 are all made of H-beams, while the other components are made of steel plates.

[0046] The pump station base in this disclosure is a welded component. Specifically, the two ends of the first crossbeam 903, the second crossbeam 904, the reinforcing beam 907, and the third crossbeam 905 are all connected to the upper surfaces of the lower parts of the first longitudinal beam 901 and the second longitudinal beam 902, thus providing support strength for the first crossbeam 903, the second crossbeam 904, the reinforcing beam 907, and the third crossbeam 905; the base plate 906 is connected to the upper surfaces of the lower parts of the first longitudinal beam 901 and the second longitudinal beam 902; the rear beam 909 is designed on the first longitudinal beam 901. On the first crossbeam 903 and 901, sufficient strength and rigidity are provided for the installation of the crankcase assembly 100. The torsion plate 912 is thicker than the first crossbeam 903 and the second crossbeam 904. The torsion plate 912 is designed to be thicker than other steel plates, which serves to strengthen the strength and rigidity of the middle part of the pump station base. The crankcase assembly 100 is bolted to the rear beam 909 located on the first crossbeam 903. The variable frequency motor is bolted to the variable frequency motor mounting base 920 located on the second crossbeam 904 and the third crossbeam 905. The second longitudinal beam 902 is provided with a cooling water pipe mounting hole 990 for the cooling water pipe to pass through. The cooling water pipe mounting hole 990 is an oblong hole.

[0047] Specifically, such as Figure 8 As shown, the lubricating oil tank is welded from steel plates and is designed with an external first oil suction port 701, a second oil suction port 702, a crankcase oil return port 704, a gearbox oil return port 703, and other necessary interfaces. The first oil suction port 701 is connected to the lubrication motor assembly for supplying oil to the lubrication motor assembly; the second oil suction port 702 is connected to the lubrication pump for supplying oil to the lubrication pump; the crankcase oil return port is connected to the oil outlet of the crankcase assembly 100, and the gearbox 400 oil return port is connected to the oil outlet of the gearbox 400; the types of interfaces on the lubricating oil tank are similar to those in the prior art and will not be described in detail here. The bottom of the lubricating oil tank is provided with a lubricating oil tank mounting position 705, which is connected to the base plate 906 and the second longitudinal beam 902 by bolts.

[0048] like Figure 4As shown, to further address the problems of low integration and disorganized cooling systems in existing fracturing pump stations, which can lead to poor heat dissipation in certain parts and require significant time and effort for customers when connecting cooling pipes, the centralized cooling system 800 includes a first centralized cooling valve 810, a second centralized cooling valve 820, and cooling pipes 890. Water in the water tank 1100 is pumped by the cooling water pump 1200 into the first centralized cooling valve 810, the second centralized cooling valve 820, and the cooling pipes 890. The cooling water enters the lubricating oil cooler 600 through the first centralized cooling valve 810, where it is cooled. The cooling water exiting the water tank 1100 enters the variable frequency motor 300 and the frequency converter 1000 through the second centralized cooling valve 820, cooling both components. The lubrication and cooling system 800 provided in this embodiment has a high degree of integration, a simple and orderly pipe layout, and is easy to install, saving time and effort.

[0049] Specifically, the water tank 1100 is connected to the inlet of the first centralized cooling valve 810 via a main pipe, and the outlet of the first centralized cooling valve 810 is connected to the first inlet pipe 840 and the second inlet pipe 850 respectively. The first inlet pipe 840 is connected to the inlet of the lubricating oil cooler, and the outlet of the lubricating oil cooler is connected to the water tank 1100. Cooling water from the water tank 1100 enters the lubricating oil cooler through the first inlet pipe 840 and then returns to the water tank 1100 through the return water pipe 860. The outlet of the second inlet pipe 850 is connected to the inlet of the variable frequency motor 300 and the inlet of the frequency converter 1000 respectively. After passing through the variable frequency motor 300 and the frequency converter 1000, the cooling water returns to the water tank 1100 through the return water pipe 860. More specifically, the outlet of the variable frequency motor 300 is connected to the first outlet pipe 870, the outlet of the frequency converter 1000 is connected to the second outlet pipe 880, and the outlet ends of the first outlet pipe 870 and the second outlet pipe 880 are connected to the return water pipe 860.

[0050] More specifically, the first centralized cooling valve 810 and the second centralized cooling valve 820 are both three-way valves with one inlet and two outlets, and the return water pipe 860 is a rubber hose.

[0051] The output end of the variable frequency motor 300 is connected to the coupling 500, the output end of the coupling 500 is connected to the gearbox 400, the output end of the gearbox 400 is connected to the crankcase assembly 100, and the output end of the crankcase assembly 100 is connected to the hydraulic end assembly 200.

[0052] The variable frequency motor 300 is the power unit of the entire fracturing pump station. It uses variable frequency technology to achieve soft starting of the variable frequency motor, avoiding the impact of traditional starting methods on the power grid, and controls the motor speed by adjusting the frequency to adapt to different load requirements.

[0053] The crankcase assembly 100 is the power unit of the fracturing pump station, converting the rotational motion of the crankshaft into the reciprocating motion of the crosshead. The crankcase assembly 100 and the gearbox 400 assembly are connected by bolts, and the crankshaft of the crankcase assembly 100 and the output gear of the gearbox 400 transmit power through internal and external spline meshing.

[0054] The hydraulic end assembly 200 is a hydraulic conversion unit of the fracturing pump station, which converts mechanical energy into pressure energy.

[0055] The lubrication and cooling system 800 includes a lubricating oil cooler 600 and a lubricating oil tank 700. The lubrication and cooling system 800 is a system that provides lubricating oil to moving parts such as crankshafts, bearings, and gears, and circulates and cools the gear oil. The fracturing pump station of the present invention optimizes the arrangement of the lubricating oil cooler 600, oil filter, tubular check valve and related pipelines. The lubricating oil cooler 600 is placed between the crankcase and the base frame assembly 900 and arranged longitudinally. The tubular check valve with internal and external lubrication is integrated into the oil inlet of the oil cooler 600 through an integrated block. The oil filter is arranged in the main pipeline of the entire lubrication and cooling system, making the pump station structure more compact and aesthetically pleasing.

[0056] The functions and connections of the crankcase assembly 100, hydraulic end assembly 200, variable frequency motor 300, coupling 500, lubricating oil cooler 600, lubricating oil tank 700, first centralized cooling valve 810, second centralized cooling valve 820, and external lubrication motor assembly described in this disclosure are similar to those of the prior art and will not be repeated here.

[0057] The pump station base provided in this disclosure, through the above design, has the lubricating oil tank 700 and the lubricating oil cooler 600 installed in the recessed hollow structure 911 at the front end of the pump station base, effectively reducing the overall height of the pump station; through the design of the intermediate torsion plate 912 and the reinforcing rib 913, the pump station base has sufficient strength and rigidity, and also makes the design of the pump station base significantly simplified and weight-reduced compared with conventional fracturing pump stations.
