Description

Technical Field

[0001] This utility model relates to the technical field of air circuit systems for oilfield machinery and equipment, specifically an air circuit system for fracturing vehicles. Background Technology

[0002] In oilfield development, fracturing trucks are key engineering equipment for implementing fracturing processes. These trucks inject fracturing fluid into the formation under high pressure to fracture the rock and release oil and gas resources. Because fracturing operations are typically conducted in remote and harsh environments, such as cold mountainous areas or hot deserts, all systems of the fracturing truck must be able to operate stably under extreme conditions. Among these, the gas supply system, a crucial component of the fracturing truck, is primarily responsible for supplying gas to the actuators, ensuring the smooth operation of the fracturing process.

[0003] Existing fracturing truck pneumatic systems typically include multiple devices such as air compressors, air tanks, filters, pressure regulators, and solenoid valves. These devices are usually installed in different locations on the fracturing truck, resulting in a large space occupied by the pneumatic system and complex connecting pipelines between the devices, increasing the difficulty of installation and maintenance. In addition, due to the dispersed layout of the equipment, the overall stability of the pneumatic system is affected, making it prone to problems such as air leaks and unstable pressure, which in turn affects the efficiency and safety of fracturing operations. Utility Model Content

[0004] This invention provides a fracturing vehicle air circuit system that can solve the technical problems of existing air circuit systems having scattered installation locations, resulting in large space occupation and inconvenience in installation and maintenance.

[0005] This application provides the following technical solution:

[0006] A fracturing vehicle air circuit system includes an installation platform and an air compressor, condenser, dryer and air tank connected in sequence by pipelines on the installation platform. The installation platform is divided into a first installation area, a second installation area and a third installation area from left to right. The air tank is horizontally installed in the first installation area. The condenser and dryer are arranged side by side in the second installation area, and the air inlet and outlet of the condenser and dryer are arranged opposite each other. The air tank is installed in the third installation area.

[0007] Beneficial effects:

[0008] 1. The main equipment, such as air compressors, condensers, dryers, and air tanks, are installed on the same platform, and the installation areas for each piece of equipment are clearly defined. This orderly layout avoids the scattered installation of equipment, greatly reduces the space occupied by the air circuit system on the fracturing truck, and leaves more space for other equipment or operating space when the space in the fracturing truck is narrow, thus improving the overall utilization rate of the vehicle space.

[0009] 2. By centralizing all equipment on a single installation platform, with each piece of equipment arranged independently and systematically, installation personnel can complete the installation and piping connections in a relatively concentrated area. This significantly simplifies the installation process, reduces installation time and workload, and improves installation efficiency. Furthermore, the centralized layout of the equipment makes maintenance work more convenient for maintenance personnel, reducing operational inconveniences caused by dispersed equipment and facilitating comprehensive inspection and maintenance of the entire gas system.

[0010] 3. The air inlets and outlets of the condenser and dryer are arranged opposite each other. This arrangement makes the layout of the gas pipeline smoother, reduces the detours and intersections of the pipeline, and thus further saves space. At the same time, this layout also facilitates the flow of gas between the equipment. After the gas comes out of the air compressor, it can pass through the condenser, dryer and air tank in sequence along a reasonable path, reducing the resistance and pressure loss of gas flow, ensuring the normal operation of the gas system and improving the working efficiency of the gas system.

[0011] Furthermore, an L-shaped support plate is fixed to the side wall of the dryer, with the support plate facing outwards, and the bottom plate of the support plate is fixed to one side of the second installation area.

[0012] Beneficial effects: The outward-facing design of the L-shaped support plate optimizes the use of installation space to a certain extent. It avoids the support plate occupying too much space around the dryer, allowing the dryer to maintain a reasonable distance from other equipment (such as condensers), which is conducive to the compactness of the overall layout of the gas path system. In addition, the outward-facing support plate can also provide some protection for the dryer body.

[0013] Furthermore, the condenser is mounted on the other side of the second mounting area via an inverted "U" bracket, and outwardly extending ear plates are provided on both sides of the bottom of the bracket, which are connected to the mounting platform.

[0014] Beneficial effects: The inverted "U" shaped bracket facilitates the installation of the condenser while not hindering maintenance and repair of the condenser's front and sides. Maintenance personnel can easily access all parts of the condenser for inspection, cleaning, and repair. The ear plate connection method also facilitates quick disassembly of the condenser when needed, improving maintenance efficiency.

[0015] Furthermore, the first installation area is also equipped with a control box, which has a start button and a stop button for controlling the air compressor to start and stop with one button.

[0016] Beneficial effects: The control box features start and stop buttons for one-touch start / stop of the air compressor, greatly simplifying the operation process. Operators no longer need to perform complex multi-step operations; they can quickly start or stop the air compressor simply by pressing the corresponding button. For example, in emergencies, the air compressor can be stopped quickly, ensuring the safety of equipment and personnel.

[0017] Furthermore, a pressure switch is installed on the top of the air tank, and the pressure switch is electrically connected to the control box. When the pressure switch detects that the pressure in the air tank has reached the preset maximum value, it sends a signal to the control box, and the control box controls the air compressor to stop working. When the pressure switch detects that the pressure in the air tank is lower than the opening value of the pressure switch, the control box controls the air compressor to start working.

[0018] Beneficial effects: By monitoring the pressure in the air storage tank in real time and feeding it back to the control box via a pressure switch, the start and stop of the air compressor can be precisely controlled, ensuring that the pressure inside the air storage tank remains within a reasonable range. This guarantees the stable operation of the air circuit system, providing a continuous and stable air supply for fracturing operations, and ensuring the continuity and stability of the fracturing process. Furthermore, it avoids the air compressor operating under extreme high or low pressure conditions for extended periods, reducing mechanical wear and tear on the equipment, extending the service life of the air compressor and related equipment in the entire air circuit system, and reducing equipment maintenance and replacement costs.

[0019] Furthermore, an air intake pipe is installed in the installation area between the control box and the condenser. One end of the air intake pipe is connected to the exhaust port of the air tank, and the other end is connected to multiple air intake branches.

[0020] Beneficial effects: Multiple air intake branches can be used for sand blowing, grease injection operations, or as backups.

[0021] Furthermore, a safety valve is also installed on the gas storage tank.

[0022] Beneficial effects: The safety valve provides a safe pressure relief function, improving the safety of use.

[0023] Furthermore, the condenser includes a condenser tube and a fixing plate. The condenser tube is an unclosed "U" shape and is configured as an interconnected multi-layer structure. The fixing plate is vertically mounted on the condenser tube. The upper part of the condenser tube is the air inlet and the lower part is the air outlet. The air inlet of the condenser tube is connected to the air outlet of the air compressor through a pipeline, and the air outlet of the condenser tube is connected to the air inlet of the dryer through a pipeline.

[0024] Beneficial effects: Due to the limited installation space in fracturing trucks, designing the condenser pipe as a curved, multi-layered structure helps reduce the space occupied by the condenser. Simultaneously, the curved structure extends the length of the condenser pipe, increasing the contact area between the gas and the inner wall of the condenser pipe, effectively removing moisture from the compressed air. The fixing plate provides support and fixation for the condenser pipe, improving its strength and stability.

[0025] Furthermore, the gas storage tank is also connected to a gas supply pipe, which is equipped with a pressure regulating valve. Several branch pipes are connected to the end of the gas supply pipe, and control valves for controlling the opening and closing of the gas circuit are installed on the branch pipes. The branch pipes are used to connect to the actuator.

[0026] Beneficial effects: The pressure regulating valve is used to regulate the pressure of the gas supply pipe, and the control valve is used to control the opening and closing of the gas circuits of each branch pipe. Attached Figure Description

[0031] The following detailed description illustrates the specific implementation method:

[0032] The markings in the accompanying drawings include: mounting platform 1, air compressor 2, condenser 3, inverted U-shaped bracket 30, condenser pipe 31, fixing plate 32, dryer 4, support plate 41, air tank 5, pressure switch 51, safety valve 52, control box 6, air intake pipe 7, air intake branch pipe 71, air supply pipe 8, pressure regulating valve 81, control valve 82, and pneumatic butterfly valve 821.

[0033] Example 1

[0034] like Figure 1 As shown, a fracturing vehicle air circuit system includes an installation platform 1 and an air compressor 2, a condenser 3, a dryer 4, and an air tank 5 connected sequentially by pipelines on the installation platform 1. The installation platform 1 is divided into a first installation area, a second installation area, and a third installation area from left to right. The air tank 5 is horizontally arranged in the first installation area, the condenser 3 and the dryer 4 are arranged side by side in the second installation area, and the air inlets and outlets of the condenser 3 and the dryer 4 are arranged opposite each other. The air tank 5 is arranged in the third installation area.

[0035] In this embodiment, the first installation area is also provided with a control box 6. The control box 6 faces outward. The control box 6 is provided with a start button, a stop button, a running indicator light, and a fault indicator light (not shown in the figure). The start button and the stop button are used to control the air compressor 2 to start and stop with one key. The indicator light is used to display the operating status of the air circuit system.

[0036] The air tank 5 is a cylindrical structure, horizontally installed in the first installation area via a bracket. Compared to a vertical arrangement, this improves the stability of the air tank 5 and the entire installation platform 1. A pressure switch 51 and a safety valve 52 are also installed on the top of the air tank 5. The pressure switch 51 is electrically connected to the control box 6, and the safety valve 52 provides overpressure protection. When the pressure switch 51 detects that the pressure inside the air tank 5 has reached a preset maximum value, it sends a signal to the control box 6, which then controls the air compressor 2 to stop working. When the pressure switch 51 detects that the pressure inside the air tank 5 is lower than its opening value, the control box 6 controls the air compressor 2 to start working.

[0037] like Figure 2 As shown, the condenser 3 is mounted on the other side of the second mounting area via an inverted U-shaped bracket 30. The bottom sides of the bracket also have outwardly extending lugs, which are connected to the mounting platform 1. Specifically, as shown... Figure 1 As shown, in this embodiment, the condenser 3 includes condenser tubes 31 and a fixing plate 32. The condenser tubes 31 are in an unclosed "U" shape and are configured as a multi-layered structure that is interconnected. The fixing plate 32 is vertically sleeved on the condenser tubes 31, providing support and fixing for the multiple condenser tubes 31. Setting the condenser tubes 31 as a curved multi-layered structure helps reduce the space occupied by the condenser 3. At the same time, the curved structure extends the length of the condenser tubes 31, increasing the contact area between the gas and the inner wall of the condenser tubes 31, effectively removing moisture from the compressed air.

[0038] The upper part of the condenser pipe 31 is the air inlet, and the lower part is the air outlet. The air inlet of the condenser pipe 31 is connected to the air outlet of the air compressor 2 through a pipeline, and the air outlet of the condenser pipe 31 is connected to the air inlet of the dryer 4 through a pipeline. An L-shaped support plate 41 is fixed to the side wall of the dryer 4, and the support plate 41 faces outward. The bottom plate of the support plate 41 is fixed to one side of the second installation area. The dryer 4 serves to filter air and remove moisture. A drain pipe and a drain valve are also provided at the bottom of the dryer 4. The drain valve is electrically connected to the control box 6. When the air pressure reaches the set pressure, the control box 6 controls the drain valve to open. When the air pressure is lower than the set closing pressure, the control box controls the drain valve to close, thereby realizing the automatic drain function.

[0039] like Figure 3 As shown, an air intake pipe 7 is also provided in the installation area between the control box 6 and the condenser 3. One end of the air intake pipe 7 is connected to the exhaust port of the air storage tank 5, and the other end is connected to multiple air intake branch pipes 71. These branch pipes 71 can be used for sandblasting and grease injection operations. Figure 4 As shown, the gas storage tank 5 is also connected to a gas supply pipe 8, which is equipped with a pressure regulating valve 81. Several branch pipes are connected to the end of the gas supply pipe 8, and control valves 82 for controlling the opening and closing of the gas circuit are installed on the branch pipes. In this embodiment, the control valve 82 is a solenoid valve. The branch pipes are used to connect to the actuator, such as connecting to a pneumatic butterfly valve 821.

[0040] In use, the compressed air generated by the air compressor 2 first enters the condenser 3, where the air exchanges heat with the condenser tube 31, condensing the water vapor in the air into liquid water. The liquid water then enters the dryer 4 along with the air. The dryer 4 separates the liquid water from the air and dries the air. Finally, the liquid water is discharged through the drain pipe at the bottom of the dryer 4.

[0041] The dried air enters the air tank 5. The pressure switch 51 on the air tank 5 monitors the pressure inside the tank in real time. When the pressure switch 51 detects that the pressure inside the air tank 5 has reached a preset maximum value, the control box 6 controls the air compressor 2 to stop working. When the pressure switch 51 detects that the pressure inside the air tank 5 is lower than its opening value, the control box 6 controls the air compressor 2 to start working, supplying clean compressed air into the air tank 5. Compressed air from the air tank 5 can be directly obtained through the air intake pipe 7 and the air intake branch pipe 71, and air can be supplied to various actuators through the air supply pipe 8.

[0042] This application provides a fracturing truck air circuit system that integrates various equipment into a single installation platform 1, featuring a compact structure, aesthetically pleasing arrangement, space saving, and ease of installation and maintenance. Furthermore, the designed condenser 3 effectively removes moisture from the air, and the air circuit control system offers advantages such as one-button start / stop, automatic shutdown, overpressure protection, and adjustable pressure, making the air circuit control of the fracturing truck more convenient and precise, and comprehensively improving the modernization level and actual operational efficiency of the fracturing truck air circuit unit.
