Description

Technical Field

[0001] The embodiments of this utility model belong to the field of boosting technology, and particularly relate to a boosting system. Background Technology

[0002] The turbocharging system is an important technological system in modern engines used to improve intake efficiency and increase engine power and torque. It increases the air pressure entering the engine cylinders, allowing the engine to burn more fuel with the same displacement, thereby improving engine performance and fuel economy.

[0003] Traditional booster compressors typically use a reciprocating piston structure for pressurization. This involves a piston reciprocating within a cylinder to draw in and compress gas, then expelling high-pressure gas. However, because booster compressors produce relatively low compressed air flow rates, they are generally only suitable for low-flow applications. Furthermore, the equipment is expensive and requires extensive maintenance. Additionally, the relatively complex structure of booster compressors necessitates a cooling system and an air tank to stabilize output pressure and temperature, leading to higher operating costs.

[0004] Furthermore, traditional turbocharging systems typically control the turbocharger accurately by monitoring its exhaust pressure. However, exhaust pressure monitoring is usually indirect and cannot directly reflect the internal condition of the turbocharger. For example, excessively high exhaust pressure may be caused by internal blockages or a malfunctioning exhaust relief valve. Therefore, relying solely on exhaust pressure monitoring is insufficient for accurate and precise control of the turbocharging system. Utility Model Content

[0005] The purpose of this invention is to design a booster system that is not only simple in structure but also meets the needs of high-flow scenarios.

[0006] To achieve the above objectives, embodiments of the present invention provide a booster system, comprising:

[0007] An air compressor; the air compressor has an inlet side and an outlet side away from the inlet side, the air compressor is used to receive low-pressure gas through the inlet side and discharge high-pressure gas through the outlet side after compression;

[0008] The first pressure detection module is used to detect the intake pressure of the air compressor when it is under load.

[0009] The main control box is communicatively connected to both the first pressure detection module and the air compressor; the main control box is used to acquire the intake pressure measured by the first pressure detection module in real time.

[0010] The main control box is used to reduce the speed of the air compressor when the obtained intake pressure is greater than the rated intake pressure; the main control box is also used to increase the speed of the air compressor when the obtained intake pressure is less than the rated intake pressure.

[0011] Compared to existing technologies, the embodiments of this utility model, since the booster system achieves boosting through an air compressor, can meet the needs of high-flow-rate applications. Furthermore, because the booster system detects the air compressor's intake pressure during operation via a first pressure detection module, the main control box can reduce the air compressor's speed when the intake pressure measured by the first pressure detection module exceeds the rated pressure, and conversely, increase the air compressor's speed when the intake pressure measured by the first pressure detection module is below the rated pressure. Therefore, compared to controlling the booster system by detecting the compressor's exhaust pressure, changing the air compressor's speed by detecting its intake pressure means that the work required by the air compressor during compression is significantly reduced, thereby effectively lowering the air compressor's energy consumption.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0015] Example 1

[0016] The first embodiment of this utility model relates to a booster system, such as Figure 1 and Figure 2 As shown, the booster system includes: an air compressor 1, a first pressure detection module 2, and a main control box 3.

[0017] In some embodiments, such as Figure 1As shown, the air compressor 1 has an intake side and an outlet side away from the intake side. The air compressor 1 is used to receive low-pressure gas through the intake side and discharge high-pressure gas through the outlet side after compression. Secondly, the first pressure detection module 2 is used to detect the intake pressure of the air compressor 1 during operation under load. Furthermore, the main control box 3 is communicatively connected to both the first pressure detection module 2 and the air compressor 1, and is used to acquire the intake pressure measured by the first pressure detection module 2 in real time.

[0018] Secondly, in some embodiments, such as Figure 1 As shown, the main control box 3 is used to reduce the speed of the air compressor 1 when the obtained intake pressure is greater than the rated intake pressure, and the main control box 3 is also used to increase the speed of the air compressor 1 when the obtained intake pressure is less than or equal to the rated intake pressure.

[0019] It is clear from the above that since the booster system achieves boosting through air compressor 1, it can meet the needs of high-flow-rate applications. Furthermore, because the booster system detects the intake pressure of air compressor 1 under load through the first pressure detection module 2, the main control box 3 can reduce the speed of air compressor 1 when the intake pressure measured by the first pressure detection module 2 is greater than the rated pressure, and conversely, increase the speed of air compressor 1 when the intake pressure measured by the first pressure detection module 2 is less than the rated pressure. Therefore, compared to controlling the booster system by detecting the exhaust pressure of the booster compressor, changing the speed of air compressor 1 by detecting its intake pressure means that the work required by air compressor 1 during compression is significantly reduced, thereby effectively reducing the energy consumption of air compressor 1.

[0020] Specifically, in some embodiments, to enable the main control box 3 to obtain the rotational speed of the air compressor 1, an encoder can be installed on the motor spindle of the air compressor 1. This encoder can detect the rotational angle of the motor spindle during operation, and it can also communicate with the main control box 3, allowing the main control box 3 to obtain the rotational angle measured by the encoder and determine the rotational speed of the air compressor 1 based on the measured angle. Secondly, the first pressure detection module 2 can be a pressure sensor. Through the first pressure detection module 2, the intake pressure of the air compressor 1 can be detected in real time. Furthermore, in some embodiments, combined with… Figure 2As shown, when setting the rated intake pressure, this rated intake pressure can be set according to different current boosting scenarios. When the intake pressure obtained by the main control box 3 is equal to the rated intake pressure, it means that the intake pressure of the air compressor 1 just meets the exhaust requirements of the boosting system. In this case, the main control box 3 does not need to change the speed of the air compressor 1. However, when the intake pressure obtained by the main control box 3 is greater than the rated intake pressure, it means that the intake pressure of the air compressor 1 is too high. In this case, the main control box 3 can reduce the speed of the air compressor 1. Finally, when the intake pressure obtained by the main control box 3 is less than the rated intake pressure, it means that the intake pressure of the air compressor 1 is too low. In this case, the main control box 3 can increase the speed of the air compressor 1.

[0021] Additionally, it is worth mentioning that in some embodiments, such as Figure 2 As shown, the booster system also includes a first pressure relief valve 4. The first pressure relief valve 4 is installed on the air compressor 1 and is also communicatively connected to the main control box 3. The main control box 3 is used to open the first pressure relief valve 4 when the intake pressure of the air compressor 1 exceeds the upper limit intake pressure, allowing the first pressure relief valve 4 to discharge gas. For example, the upper limit intake pressure is a safety pressure to protect the air compressor 1, and this upper limit intake pressure should be greater than the rated intake pressure. Therefore, if the intake pressure of the air compressor 1 measured by the first pressure detection module 2 exceeds the upper limit intake pressure, it indicates that the intake pressure of the air compressor 1 is too high, which may cause knocking or damage to the air compressor 1. Therefore, to avoid this phenomenon, the main control box 3 can open the first pressure relief valve 4 to discharge gas, thereby effectively reducing the pressure inside the air compressor 1.

[0022] Furthermore, as a preferred embodiment, in other embodiments, such as Figure 1 As shown, the booster system also includes an intake buffer tank 5, which is connected to the first pressure relief valve 4 and is used to receive the gas discharged from the first pressure relief valve 4. It is evident that the intake buffer tank 5 can store excess gas discharged from the air compressor 1, thereby effectively reducing pressure fluctuations in the air compressor 1 of the booster system, ensuring stable airflow, and preventing pressure fluctuations from damaging the equipment.

[0023] Additionally, as a preferred embodiment, in other embodiments, such as Figure 2As shown, the booster system also includes an intake valve 6, which is located on the intake side of the air compressor 1 and is communicatively connected to the main control box 3. The intake valve 6 can be used to open or close the intake side of the air compressor 1. Specifically, the main control box 3 is also used to control the intake valve 6 to close the intake side of the air compressor 1 when the intake pressure of the air compressor 1 is less than the lower intake limit pressure, thus allowing the air compressor 1 to operate without load. The lower intake limit pressure is less than the rated intake pressure. Therefore, when the intake pressure obtained by the main control box 3 is less than the lower intake limit pressure, it indicates that the intake pressure of the air compressor 1 is too low. If the main control box 3 simply increases the speed of the air compressor 1, it will not only greatly increase the energy consumption of the air compressor 1, but also fail to effectively increase the intake pressure of the air compressor 1. Therefore, when the intake pressure of the air compressor 1 is less than the lower intake limit pressure, the main control box 3 can control the intake valve 6 to close the intake side of the air compressor 1, allowing the air compressor 1 to operate without load. When the main control box 3 receives the air compressor 1's intake pressure and it reaches the rated pressure, it controls the intake valve 6 to reopen the air compressor 1's intake side, allowing the air compressor 1 to be reloaded and run.

[0024] Furthermore, excessively high exhaust pressure in air compressor 1 will cause the pistons, cylinders, valves, and other components inside air compressor 1 to bear a greater load, leading to accelerated wear and shortening the lifespan of air compressor 1. It will also increase the load on the motor of air compressor 1, potentially causing motor overload or even burnout during prolonged operation. Therefore, in other embodiments, such as... Figure 2 As shown, the booster system also includes a second pressure detection module 7, which is communicatively connected to the main control box 3. This second pressure detection module 7 is used to detect the first exhaust pressure of the air compressor 1 during loading operation in real time. Furthermore, the main control box 3 is also used to acquire the first exhaust pressure measured by the second pressure detection module 7, and to control the intake valve 6 to close the intake side of the air compressor 1 when the first exhaust pressure of the air compressor 1 is greater than or equal to the upper exhaust pressure, thus allowing the air compressor 1 to operate without load. Therefore, it is easy to see that when the first exhaust pressure of the air compressor 1 is too high, the main control box 3 controls the intake valve 6 of the air compressor 1 to close the intake side of the air compressor 1, allowing the air compressor 1 to operate without load, thereby achieving the purpose of protecting the air compressor 1.

[0025] Furthermore, in order to quickly reduce the discharge pressure of air compressor 1 when the first discharge pressure of air compressor 1 is too high, in other embodiments, such as... Figure 2 As shown, the booster system also includes a second pressure relief valve 8, which is installed on the air compressor 1 and communicates with the main control box 3. Therefore, when the first exhaust pressure of the air compressor 1 obtained by the main control box 3 is greater than or equal to the upper limit exhaust pressure, the main control box 3 can open the second pressure relief valve 8 to discharge gas, thereby achieving the purpose of quickly reducing the exhaust pressure of the air compressor 1. However, as a preferred embodiment, in other embodiments, such as... Figure 1 As shown, the booster system also includes an exhaust buffer tank 9, which is also connected to the air compressor 1. The exhaust buffer tank is used to receive the gas discharged from the second pressure relief valve 8. It is easy to see that the exhaust buffer tank 9 can absorb and mitigate pressure fluctuations in the exhaust system, thereby ensuring smooth airflow and preventing pressure fluctuations from impacting or damaging the user end.

[0026] In addition, in some other embodiments, the main control box 3 is also used to obtain the duration of the air compressor 1's no-load operation when the air compressor 1 is running under no-load conditions. Furthermore, the main control box 3 can also control the air compressor 1 to enter a sleep state when the obtained duration reaches a preset duration, so that the air compressor 1 can stop running at this time, thereby greatly reducing the energy consumption of the air compressor 1.

[0027] Furthermore, it is worth noting that after the air compressor 1 has been running under no-load conditions, or after the air compressor 1 has entered a dormant state, in order to enable the air compressor 1 to resume loading operation as quickly as possible, in some other embodiments, such as... Figure 2 As shown, the second pressure detection module 7 is also used to detect the second exhaust pressure of the air compressor 1 when the air compressor 1 is running under no-load or in a dormant state. At the same time, the main control box 3 is also used to acquire the second exhaust pressure measured by the second pressure detection module 7. Furthermore, when the acquired second exhaust pressure is less than or equal to the rated exhaust pressure, the main control box 3 is used to control the intake valve 6 to open the intake side of the air compressor 1, so that the air compressor 1 can be reloaded and run.

[0028] As can be seen from the above, when air compressor 1 is running under load, it will only enter no-load operation or sleep mode when the first discharge pressure reaches or exceeds the upper limit discharge pressure. Furthermore, when air compressor 1 enters no-load operation or sleep mode, the second discharge pressure of air compressor 1 during no-load operation or sleep mode can be detected by the second pressure detection module 7. The main control box 3 can obtain the second discharge pressure measured by the second pressure detection module 7. When the second discharge pressure measured by the second pressure detection module 7 is less than or equal to the rated discharge pressure, it indicates that the discharge pressure of air compressor 1 has become stable and safe. At this time, the main control box 3 can control the intake valve to reopen the intake side of air compressor 1 and simultaneously close the second pressure relief valve 8, allowing air compressor 1 to resume operation under load.

[0029] Additionally, in other embodiments, such as Figure 1 and Figure 2As shown, the booster system also includes an air supply device 10, which is located on the intake side of the air compressor 1 and is communicatively connected to the main control box 3. The air supply device 10 receives drive commands from the main control box 3 and, upon receiving the commands, supplies air to the intake side of the air compressor 3, thereby cooling the crankcase of the air compressor 1. This also prevents oil buildup in the crankcase of the air compressor 1 caused by oil cooling, thus reducing wear on the crankcase during operation and extending the service life of the air compressor 1.

[0030] Furthermore, as a preferred embodiment, in other embodiments, such as Figure 2 As shown, the air compressor 1 also includes a temperature detection module 11, which is installed on the air compressor 1 and communicates with the main control box 3. The temperature detection module 11 can be used to detect the temperature inside the air compressor 1 in real time. The main control box 3 is also used to obtain the temperature measured by the temperature detection module 11 and to turn on the air supply device 10 when the obtained temperature is greater than or equal to the preset temperature, so that the air supply device 10 can cool the air compressor 1.

[0031] Specifically, in some embodiments, the temperature detection module 11 can be a temperature sensor installed inside the crankcase of the air compressor 1, which enables real-time detection of the temperature inside the crankcase. Furthermore, when the temperature received by the main control box 3 is greater than a preset temperature, the main control box 3 can send a drive command to the air supply device 10, causing the air supply device 10 to supply air to the intake side of the air compressor 1 at a preset power. Moreover, as a preferred embodiment, when the temperature obtained by the main control box 3 is greater than or equal to the preset temperature, and simultaneously when the temperature obtained by the main control box 3 is greater than the temperature at the previous moment, the main control box 3 can send a power enhancement command to the air supply device 10, causing the main control box 3 to increase the air supply force of the air supply device 10. For example, if the preset temperature is 80 degrees Celsius, and the temperature received by the main control box 3 at the previous moment was 85 degrees Celsius, then the main control box 3 sent a drive command to the air supply device 10 at the previous moment. The air supply device 10 was turned on at the previous moment and was in the state of supplying air to the intake side of the air compressor 1. However, the temperature received by the main control box 3 at the present moment is 90 degrees Celsius, which is greater than the temperature received at the previous moment. This indicates that the air supply force of the air supply device 10 to the intake side of the air compressor 1 is too small and is insufficient to reduce the temperature inside the crankcase of the air compressor 1. At this time, the main control box 3 can send a power enhancement command to the air compressor 1, so that the air supply device 10 can increase the current air supply force to the intake side of the air compressor 1.

[0032] Conversely, when the temperature received by the main control box 3 is lower than the temperature received at the previous moment, the main control box 3 can send a power reduction command to the air supply device 10, so that the air supply device 10 can reduce the force of air supply to the intake side of the air compressor 1. For example, if the preset temperature is 80 degrees, and the temperature received by the main control box 3 at the previous moment was 90 degrees, then the main control box 3 has already sent a drive command to the air supply device 10 at the previous moment. The air supply device 10 was turned on and was in the state of supplying air to the intake side of the air compressor 1 at the previous moment. The current temperature received by the main control box 3 is 85 degrees, which is lower than the temperature received at the previous moment. This means that the air supply force of the air supply device 10 to the intake side of the air compressor 1 is sufficient to reduce the temperature inside the crankcase 2. However, in order to reduce the energy consumption of the booster system, the main control box 3 can send a power reduction command to the air supply device 10, so that the air supply device 10 can appropriately reduce the current air supply force to the air compressor 1.

[0033] Finally, when the temperature received by the main control box 3 is lower than the preset temperature, it means that the temperature inside the air compressor 1 is within the normal operating temperature range. If the air supply device 10 is currently in operation, the main control box 3 can shut down the air supply device 10, thereby further reducing the energy consumption of the air compressor 1.

[0034] Additionally, it is worth noting that in some embodiments, the booster system further includes a mounting plate 12, which supports the air compressor 1, the main control box 3, the intake buffer tank 5, and the exhaust buffer tank 9, and has several mounting holes. The air compressor 1, the main control box 3, the intake buffer tank 5, and the exhaust buffer tank 9 can be integrated via the mounting plate 12, and the mounting holes on the mounting plate 12 facilitate the installation and fixation of the booster system.

[0035] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
