[0028] DETAILED DESCRIPTION Figure 8

[0029] ​​To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0030] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0031] As mentioned above, fracturing equipment typically includes a main power unit, multiple auxiliary power units, and some supporting devices. These supporting devices include functional components such as diffusers and silencers to achieve functions such as exhaust and noise reduction. During assembly, these components of fracturing equipment are usually arranged laterally and are large in size and weight, which makes assembly difficult and labor-intensive.

[0032] Figure 1 A schematic diagram of the diffuser and silencer sections of a fracturing device is shown, such as... Figure 1 As shown, the fracturing equipment has a chamber sidewall 1, and a diffuser 2 is installed on the chamber sidewall 1. One end of the diffuser 2 passes through a bellows 3 and connects to a silencer 4, while the other end connects to a turbine (not shown in the figure). During the installation of the diffuser 2 onto the chamber sidewall 1, due to its weight, large size, and relatively soft sealing connection with the chamber sidewall 1, it is difficult to align the diffuser 2 with the turbine and fix it to the chamber sidewall 1, often requiring multiple people to assist in the installation. For example, after aligning the diffuser 2 with the turbine, the fixing plate 5 of the diffuser 2 needs to be fixed to the chamber sidewall 1 by welding or bolting to complete the assembly of the diffuser 2. This assembly method is difficult, labor-intensive, and time-consuming.

[0033] The exhaust device provided by at least one embodiment of the present disclosure comprises a body, a fixing plate, a pressing plate and a diffusion pipe; the body comprises a side wall; the fixing plate is configured to be fixed to the side wall; the pressing plate is configured to be pre-fixedly connected and fixedly connected with the fixing plate; the diffusion pipe is configured to be fixed to the side wall through the pressing plate and the fixing plate; the fixing plate further comprises a first pre-mounting portion, and the pressing plate further comprises a second pre-mounting portion, and the second pre-mounting portion cooperates with the first pre-mounting portion to realize pre-fixing of the diffusion pipe. In the assembly process of the exhaust device, the first pre-mounting portion of the fixing plate and the second pre-mounting portion of the pressing plate can realize pre-fixing of the diffusion pipe through cooperation, and then the diffusion pipe is fixed, so that the diffusion pipe and other components (for example, a turbine) can be initially aligned through pre-fixing, and then the diffusion pipe is accurately connected through fixing, and in the subsequent alignment and fixing process, the diffusion pipe does not need to be supported by manpower and the alignment of the diffusion pipe does not need to be operated by manpower, so that although the pre-fixing process is increased, the assembly process can be actually simplified and manpower and time can be saved, and the assembly efficiency is improved.

[0034] The exhaust device provided by at least one embodiment of the present disclosure, the mounting method thereof and the fracturing equipment are described in detail below through several specific examples.

[0035] The exhaust device provided by at least one embodiment of the present disclosure, Figure 2 An exploded view of the exhaust device is shown. As shown in the figure, Figure 2 The exhaust device comprises a body 100, a fixing plate 10, a pressing plate 11 and a diffusion pipe S; the body 100 comprises a side wall 100A; the fixing plate 10 is configured to be fixed to the side wall 100A; the pressing plate 11 is configured to be pre-fixedly connected and fixedly connected with the fixing plate 10; and the diffusion pipe S is configured to be fixed to the side wall 100A through the pressing plate 11 and the fixing plate 10.

[0036] For example, in the embodiment of the present disclosure, the body 100, the fixing plate 10, the pressing plate 11 and the diffusion pipe S can be in a state to be assembled or a state to be assembled.

[0037] For example, Figure 3 An exploded view of the exhaust device in Figure 2 is shown. As shown in the figure, Figure 2 and Figure 3 The fixing plate 10 further comprises a first pre-mounting portion 101, and the pressing plate 11 further comprises a second pre-mounting portion 111, and the second pre-mounting portion 111 cooperates with the first pre-mounting portion 101 to realize pre-fixing of the diffusion pipe S. For example, the cooperation between the second pre-mounting portion 111 and the first pre-mounting portion 101 can comprise plug-in connection, lap joint, clamping connection and the like, and the cooperation mode between the second pre-mounting portion 111 and the first pre-mounting portion 101 is not limited in the embodiment of the present disclosure.

[0038] For example, in some embodiments, the second pre-mounting portion 111 and the first pre-mounting portion 101 are configured to achieve pre-fixing of the diffuser pipe S by plugging. For example, one of the second pre-mounting portion 111 and the first pre-mounting portion 101 comprises a recessed portion, and the other of the second pre-mounting portion 111 and the first pre-mounting portion 101 comprises a protruding portion, at least part of the protruding portion is located in the recessed portion in the case of plugging of the second pre-mounting portion 111 and the first pre-mounting portion 111, thereby achieving pre-fixing of the diffuser pipe S.

[0039] For example, as shown in FIG. 1A, the side wall 100A has a mounting opening 100B, the fixing plate 10 has a first opening 10A through which the diffuser pipe S passes, and the pressing plate 11 has a second opening 11A through which the diffuser pipe S passes; the diffuser pipe S is configured to be fixed on the side wall 100A by passing through the mounting opening 100B, the first opening 10A and the second opening 11A. For example, the middle portion S0 of the diffuser pipe S is configured as a portion fixed to the side wall 100A. Figure 2

[0040] For example, in some embodiments, as shown in FIG. 1A, the fixing plate 10 can comprise a first plate surface 102, the first pre-mounting portion 101 comprises a first mounting portion 103 protruding from the first plate surface 102 in the axial direction (i.e. the horizontal direction in the figure), and the first mounting portion 103 at least partially surrounds the first opening 10A. As shown in FIG. 1A, the first pre-mounting portion 10 further comprises a first baffle plate 104 protruding from the side of the first mounting portion 103 facing the first opening 10A towards the first opening 10A, and the first baffle plate 104 is spaced apart from the first surface 103A of the first mounting portion 103 which is spaced apart from the first plate surface 102 in the axial direction by a predetermined distance, so that the first pre-mounting portion 101 is configured as a recessed portion for plugging, and at least part of the recessed portion is defined by the first baffle plate 104 and the first mounting portion 103, i.e. the portion shown by the dashed line in FIG. 1A. Figure 2 Figure 3 Figure 3 Figure 3

[0041] For example, in the case of cooperation of the first pre-mounting portion 101 and the second pre-mounting portion 111, the first surface 103A of the first mounting portion 10 faces at least part of the pressing plate 11. For example, a sealing ring can be provided between the first surface 103A and the pressing plate 11 for sealing the fixing plate 10 and the pressing plate 11.

[0042] For example, in some embodiments, as shown in FIG. 1A, the fixing plate 10 can comprise a first plate surface 102, the first pre-mounting portion 101 comprises a first mounting portion 103 protruding from the first plate surface 102 in the axial direction (i.e. the horizontal direction in the figure), and the first mounting portion 103 at least partially surrounds the first opening 10A. As shown in FIG. 1A, the first pre-mounting portion 10 further comprises a first baffle plate 104 protruding from the side of the first mounting portion 103 facing the first opening 10A towards the first opening 10A, and the first baffle plate 104 is spaced apart from the first surface 103A of the first mounting portion 103 which is spaced apart from the first plate surface 102 in the axial direction by a predetermined distance, so that the first pre-mounting portion 101 is configured as a recessed portion for plugging, and at least part of the recessed portion is defined by the first baffle plate 104 and the first mounting portion 103, i.e. the portion shown by the dashed line in FIG. 1A. Figure 2 Figure 3 ​​​​​​As shown, the pressing plate 11 can include a second plate surface 112, and the second pre-mounting portion 111 includes a first protruding portion 113 protruding from the second plate surface 112 in the axial direction (i.e., the horizontal direction in the figure), and the first protruding portion 113 at least partially surrounds the second opening 11A. In the case where the first pre-mounting portion 101 cooperates with the second pre-mounting portion 111, a second surface 113A of the first protruding portion 113 spaced apart from the second plate surface 112 in the axial direction faces the third surface 104A of the first baffle plate 104. For example, a sealing ring can be arranged between the second surface 113A and the third surface 104A of the first baffle plate 104 for sealing the fixing plate 10 and the pressing plate 11.

[0043] For example, in the case where the first pre-mounting portion 101 cooperates with the second pre-mounting portion 111, as shown in FIG. 1C, at least part of the first protruding portion 113 is located in the first pre-mounting portion 101, i.e., at least part of the first protruding portion 113 is located in the recess defined by the first baffle plate 104 and the first mounting portion 103, and at this time, the third surface 104A of the first baffle plate 104 serves as at least part of the bottom surface of the recess. Figure 3 For example, in the case where the first pre-mounting portion 101 cooperates with the second pre-mounting portion 111, as shown in FIG. 1C, at least part of the first protruding portion 113 is located in the first pre-mounting portion 101, i.e., at least part of the first protruding portion 113 is located in the recess defined by the first baffle plate 104 and the first mounting portion 103, and at this time, the third surface 104A of the first baffle plate 104 serves as at least part of the bottom surface of the recess.

[0044] For example, in some embodiments, the first mounting portion 103 is a first closed ring structure surrounding the first opening 10A, and the first protruding portion 113 is a second closed ring structure surrounding the second opening 11A. In the case where the first pre-mounting portion cooperates with the second pre-mounting portion, the second closed ring structure is located radially inside the first closed ring structure, i.e., in this embodiment, the first pre-mounting portion 101 includes a recess defined by the first baffle plate 104 and the first mounting portion 103, and the second pre-mounting portion 111 includes a protrusion defined by the first protruding portion 113, and in the case where the first pre-mounting portion 101 cooperates with the second pre-mounting portion 111, at least part of the second pre-mounting portion 111 (e.g., the protrusion defined by the first protruding portion 113) is inserted into the first pre-mounting portion (e.g., the recess defined by the first baffle plate 104 and the first mounting portion 103), thereby achieving insertion and further achieving pre-fixing of the diffusion pipe.

[0045] For example, in some embodiments, as shown in FIG. 1C and FIG. 1D, Figure 2 and Figure 3 For example, in some embodiments, as shown in FIG. 1C and FIG. 1D, For example, in some embodiments, as shown in FIG. 1C and FIG. 1D,

[0046] For example, as shown in Figure 2 and Figure 3 The exhaust device can further include a third sealing portion S3, which can be arranged between the fixed plate 10 and the diffuser pipe S, for sealing the fixed plate 10 and the diffuser pipe S.

[0047] For example, Figure 4 A plan view of the fixed plate is shown, Figure 5 A partial cross-sectional view of the exhaust device in Figure 2 is shown in the lower dashed box area after assembly. For example, in some embodiments, the first mounting portion 103 has at least one threaded hole 1031 extending in a direction parallel to the first plate surface 102 (vertical direction in Figure 5 , which communicates with the first opening 10A, in a direction perpendicular to the first plate surface 102 (horizontal direction in Figure 5 , the at least one threaded hole 1031 is located between the first baffle 104 and the first surface 103A of the first mounting portion 103, as shown in Figure 5 .

[0048] For example, a jackscrew 1032 can be screwed into the at least one threaded hole 1031, at which time the jackscrew 1032 can abut against the first protrusion 113 on the pressing plate 11, thereby achieving fine adjustment of the position of the pressing plate 11 and further achieving fine adjustment of the diffuser pipe S.

[0049] For example, as shown in Figure 4 The at least one threaded hole 1031 can include a plurality of threaded holes 1031, which can be arranged around the first opening 10A. For example, in some examples, the plurality of threaded holes 1031 can be arranged around the first opening 10A once, or around the first opening 10A half on the lower side of the first opening 10A (as shown in Figure 4 Since the fixed plate 10 on the lower side of the first opening 10A is the side that bears the weight of the diffuser pipe S, the threaded hole 1031 and the jackscrew 1032 can be arranged on the lower side of the first opening 10A to achieve fine adjustment of the position of the diffuser pipe S at least in the direction of gravity, thereby achieving the effect of accurately installing the diffuser pipe S.

[0050] In the assembly process of the above-described exhaust device provided by the embodiments of the present disclosure, the first pre-mounting portion 101 of the fixed plate 10 and the second pre-mounting portion 111 of the pressing plate 11 can cooperate to achieve pre-fixing of the diffuser pipe S, thereby achieving initial alignment of the diffuser pipe S with other components (such as a turbine), and then the diffuser pipe S is fixed, for example, the fixed plate 10 and the pressing plate 11 are fixedly connected by using the bolts 131, as shown in Figure 2 and Figure 5As shown, the accurate connection of the diffusion pipe can be achieved by the assembly method of pre-fixing and then fixing, which can simplify the assembly process, save labor and time, and improve the assembly efficiency. Furthermore, the position of the diffusion pipe S can be adjusted by the jack screw, and the diffusion pipe is fixed after being adjusted to the appropriate position, thereby improving the assembly efficiency and assembly accuracy.

[0051] For example, in some embodiments, the first pre-mounting part 101 on the fixing plate 10 and the second pre-mounting part 111 on the pressing plate 11 can also adopt a structure different from the above-described embodiments.

[0052] For example, Figure 6 Another cross-sectional view of the cooperation between the first pre-mounting part and the second pre-mounting part according to at least one embodiment of the present disclosure is shown. In combination with Figure 2 and Figure 6 In this embodiment, the fixing plate 10 includes a first plate surface 101, the first pre-mounting part 101 includes a second mounting part 201 protruding from the first plate surface 102 in the axial direction, the second mounting part 201 at least partially surrounds the first opening 10A, and the surface 201A of the second mounting part 201 spaced apart from the first plate surface 101 in the axial direction includes a groove 202 extending toward the first plate surface 101 in a direction perpendicular to the first plate surface 101 (the horizontal direction in the figure), and the groove 202 is configured to accommodate at least part of the protruding part (for example, the second protruding part 211 described later).

[0053] For example, in combination with Figure 2 and Figure 6 The pressing plate 11 includes a second plate surface 112, the second pre-mounting part 111 includes a second protruding part 211 protruding from the second plate surface 112 in the axial direction, the second protruding part 211 at least partially surrounds the second opening 11A, and the second protruding part 211 is configured to be inserted into the groove 202, so that at least part of the second protruding part 211 is located in the groove 202 of the second mounting part 201, realizing the insertion of the first pre-mounting part and the second pre-mounting part.

[0054] For example, in some embodiments, the second mounting part 201 is a first closed ring structure surrounding the first opening 10A, and the second protruding part 211 is a second closed ring structure surrounding the second opening 11A. In this embodiment, the first pre-mounting part 101 includes a recess defined by the groove 202 of the second mounting part 201, and the second pre-mounting part 111 includes a protruding part defined by the second protruding part 211. When the first pre-mounting part and the second pre-mounting part cooperate, at least part of the second pre-mounting part (for example, the second protruding part 211) is inserted into the first pre-mounting part (for example, the groove 202 of the second mounting part 201), thereby realizing the insertion, and further realizing the pre-fixing of the diffusion pipe.

[0055] For example, asFigure 6 As shown, the first side wall 201A of the second mounting portion 201, which is away from the first opening 10A in the radial direction (vertical direction in the figure), has at least one threaded hole 221 extending in a direction parallel to the second plate surface 111 (vertical direction in the figure) and penetrating through the first side wall 201A.

[0056] For example, a jackscrew 222 can be screwed into the at least one threaded hole 221, and the jackscrew 222 can abut against the second protrusion 211 on the pressure plate 11, so as to fine-tune the position of the pressure plate 11, and further fine-tune the position of the diffuser pipe S.

[0057] For example, similar to Figure 4 As shown, the at least one threaded hole 221 can include a plurality of threaded holes 221, which can be arranged around the first opening 10A. For example, in some examples, the plurality of threaded holes 221 can be arranged around the first opening 10A in one circle, or around the first opening 10A in half a circle on the lower side of the first opening 10A. Since the fixed plate 10 on the lower side of the first opening 10A is the side that bears the weight of the diffuser pipe S, the threaded holes 221 and the jackscrews 222 can be arranged on the lower side of the first opening 10A to fine-tune the position of the diffuser pipe S at least in the direction of gravity, and further achieve the effect of accurately installing the diffuser pipe S.

[0058] Similarly, in the assembly process of the exhaust device provided in the above embodiment of the present disclosure, the first pre-mounting portion 101 of the fixed plate 10 and the second pre-mounting portion 111 of the pressure plate 11 can cooperate to pre-fix the diffuser pipe S, and further pre-align the diffuser pipe S with other components (such as a turbine), and then fix the diffuser pipe S, for example, use the bolts 131 to fixedly connect the fixed plate 10 and the pressure plate 11, as shown in Figure 2 and Figure 6 As shown, the pre-fixing and then fixing assembly method can achieve accurate connection of the diffuser pipe, which can simplify the assembly process, save labor and time, and improve assembly efficiency.

[0059] For example, Figure 7 Another cross-sectional view of the cooperation between the first pre-mounting portion and the second pre-mounting portion is shown. In combination with Figure 2 and Figure 7 In this embodiment, the fixed plate 10 includes a first plate surface 102, the first pre-mounting portion 101 includes a third mounting portion 301 protruding from the first plate surface 102 in the axial direction (horizontal direction in the figure), the third mounting portion 301 at least partially surrounds the first opening 10A, and the third mounting portion 301 constitutes a protrusion.

[0060] For example, the pressing plate 11 includes a second plate surface 112, and the second pre-mounting portion includes a third protruding portion 311 protruding from the second plate surface 112 in the axial direction (horizontal direction in the figure), the third protruding portion 311 at least partially surrounding the second opening 11A. In this embodiment, the recessed portion is defined by the third protruding portion 311. For example, when the first pre-mounting portion 101 cooperates with the second pre-mounting portion 111, at least part of the third mounting portion 301 is inserted into the recessed portion defined by the third protruding portion 311 and the second plate surface 111, as shown in Figure 7 .

[0061] For example, in some embodiments, the third mounting portion 301 is a first closed ring-like structure surrounding the first opening 10A, and the third protruding portion 311 is a second closed ring-like structure surrounding the second opening 11A. When the first pre-mounting portion cooperates with the second pre-mounting portion, the second closed ring-like structure is radially outside the first closed ring-like structure and is radially the outermost of the pressing plate 11, the side surface of the recessed portion is constituted by the radially inner surface of the third protruding portion 311, and the bottom surface of the recessed portion is the second plate surface 111.

[0062] For example, in some embodiments, as shown in Figure 7 , the third protruding portion 311 has at least one threaded hole 312 extending in a direction parallel to the second plate surface 111 (vertical direction in the figure) and penetrating through the third protruding portion 311.

[0063] For example, a jackscrew 313 can be screwed into the at least one threaded hole 312, and the jackscrew 313 can abut against the third mounting portion 301, thereby achieving fine adjustment of the position of the fixing plate 10 and further achieving fine adjustment of the position of the diffusion tube S.

[0064] For example, similar to the case shown in Figure 4 , the at least one threaded hole 312 can include a plurality of threaded holes 312, and the plurality of threaded holes 312 can be arranged around the first opening 10A. For example, in some examples, the plurality of threaded holes 312 can be arranged around the first opening 10A in one circle, or around the first opening 10A in half a circle on the lower side of the first opening 10A. Since the fixing plate 10 on the lower side of the first opening 10A is the side that bears the weight of the diffusion tube S, by arranging the threaded holes 312 and the jackscrews 313 on the lower side of the first opening 10A, fine adjustment of the position of the diffusion tube S in at least the direction of gravity can be achieved, thereby achieving the effect of accurately installing the diffusion tube S.

[0065] Similarly, in the assembly process of the exhaust device provided in the embodiments of the present disclosure, the first pre-mounting portion 101 of the fixed plate 10 and the second pre-mounting portion 111 of the pressing plate 11 can realize the pre-fixing of the diffusion pipe S through mutual cooperation, and then realize the initial alignment of the diffusion pipe S and other components (for example, a turbine), and then the diffusion pipe S is fixed, for example, the fixed plate 10 and the pressing plate 11 are fixed and connected by using the bolts 131, as shown in Figure 2 and Figure 7 Thus, the accurate connection of the diffusion pipe can be realized through the assembly method of pre-fixing and then fixing, which can simplify the assembly process and save manpower and time, thereby improving the assembly efficiency.

[0066] At least one embodiment of the present disclosure also provides a turbofracturing device, Figure 8 a schematic view of the turbofracturing device is shown. As shown in Figure 8 the turbofracturing device includes a silencing cabin 41 and the exhaust device provided in the embodiments of the present disclosure. For example, the turbine 42 is arranged in the silencing cabin 41, for example, the silencing cabin 41 has a containing space 110, and the turbine 42 is arranged in the containing space 110. For example, the silencing cabin 41 is provided with a silencer 43 outside, the silencing cabin 41 has a side wall (i.e., the position indicated by the mark 41), the diffusion pipe S is mounted on the side wall, and the two ends of the diffusion pipe S are connected with the turbine 42 and the silencer 43 respectively, and the silencer 43 is used for silencing and guiding the exhaust gas discharged from the turbine 42 through the diffusion pipe S to be discharged into the atmosphere.

[0067] For example, in some embodiments, as shown in Figure 8 the silencer 43 includes an L-shaped gas transmission passage 201, one end of the gas transmission passage 201 has an air inlet which communicates with the turbine 42 through the diffusion pipe S to intake air, and the other end has an upward air outlet to facilitate the exhaust gas generated by the turbine 42 to be discharged to the atmosphere.

[0068] For example, as shown in Figure 8 the turbofracturing device can further include an air inlet device 44 and a cleaning device 140 and the like. For example, the turbine 42 and the cleaning device 140 are located in the containing space 110. For example, the air inlet device 44 is located at the top of the silencing cabin 41 and communicates with the turbine 42 through an air inlet pipe 131 and is configured to provide combustion-supporting gas to the turbine 42. For example, the air inlet device 44 includes a plurality of air inlets 132 arranged side by side. For example, the air inlet device 44 is fixed on the top of the silencing cabin 41 by welding or the like. For example, the cleaning device 140 is located on the side of the turbine 42 away from the air inlet device 44, i.e., below the turbine engine. For example, the cleaning device 140 includes a water tank 141 and a cleaning pump 142.

[0069] For example, as shown inFigure 8 As shown, the turbine fracturing equipment may also include a reduction gear 16 and a second lubrication system 161 located within the anechoic chamber 41. The second lubrication system 161 is configured to lubricate the reduction gear 16. The reduction gear 16 is connected to the output shaft of the turbine 42 and is arranged axially with the turbine 42. For example, the second lubrication system 161 includes a second lubricating oil tank 161a and a second drive mechanism 161b, which includes an electric motor; that is, the second lubrication system 161 is electrically driven, thus allowing for a smaller size.

[0070] For example, such as Figure 8 As shown, the turbine fracturing equipment may also include an air inlet assembly 18 and an air outlet assembly 19. The air inlet assembly 18 and the air outlet assembly 19 are used to create a circulating environment within the anechoic chamber, which helps with heat dissipation within the chamber. For example, the air outlet assembly 19 includes an air outlet duct 191 and a discharge section 192 connected to the air outlet duct 191. The discharge section 192 is used to change the orientation of the air outlet of the air outlet assembly, thereby effectively reducing the damage caused by windblown sand entering the anechoic chamber from the air outlet assembly and affecting the materials within the chamber.

[0071] For example, such as Figure 8 As shown, the turbine fracturing equipment may further include a transmission mechanism 45, a fracturing pump 21, and a third lubrication system 22 for lubricating the fracturing pump 21. The third lubrication system 22 includes an electric motor 221 located on the side of the transmission mechanism 45 away from the air intake device 44.

[0073] For example, such as Figure 8 As shown, the turbine fracturing equipment may also include a fracturing pump base 24 located below the fracturing pump 21. The fracturing pump base 24 is used to elevate the fracturing pump 21 so that the fracturing pump 21 and the turbine 42 are aligned in a straight line along the axial direction of the turbine 42, thereby improving transmission efficiency.

[0074] For example, such as Figure 8 As shown, the turbine fracturing equipment may also include a skid 6, on which the aforementioned components are mounted for fixation.
