Description

Technical Field

[0001] The invention relates to the technical field of air compressors, and in particular to an air intake volume regulating device for air compressors. Background Art

[0002] An air compressor is a mechanical device that compresses air and stores it for subsequent use. By reducing the volume of the gas to increase the gas pressure, the compressed air can be used in a variety of fields, such as car repair, painting, construction, manufacturing plants, cleaning work, etc. The air intake regulating device of the air compressor is used to control the air flow entering the compressor, thereby affecting the working efficiency and output pressure of the compressor. These devices are usually used to adjust the output of the compressor according to actual needs, avoid unnecessary energy waste, and ensure stable operation of the system.

The internal combustion engine is provided with: an electric supercharger, the electric supercharger includes an electric compressor; an EGR inlet, the EGR inlet is formed upstream of the electric compressor; a throttle, the throttle is arranged upstream of the EGR inlet; and a control device. Throttle valves other than the throttle valve are not arranged in the intake passage. The control device is configured to: perform a first air flow regulation process and a second air flow regulation process in a non-boosting area, the first air flow regulation process regulates the intake flow by regulating the opening of the throttle while driving the electric supercharger to make the pressure ratio of the electric compressor close to 1; the second air flow regulation process regulates the intake flow by regulating the opening of the throttle valve while not energizing the electric supercharger.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, an air compressor intake amount regulating device of the present invention comprises a support frame 1, a compression mechanism 2 is arranged on the support frame 1, an air storage cylinder 3 connected with the compression mechanism 2 is arranged on the support frame 1, the air storage cylinder 3 is connected with the working equipment, and a driving mechanism 4 is arranged on the support frame 1, and the driving mechanism 4 is used to drive the compression mechanism 2 to move so that the compression mechanism 2 compresses air;

[0036] The compression mechanism 2 is provided with an air intake regulating assembly 5 for controlling the air intake amount, the air storage cylinder 3 is provided with an upper connecting assembly 6 connected with the air intake regulating assembly 5, and the upper connecting assembly 6 is provided with a lower connecting assembly 7 connected with the air intake regulating assembly 5;

[0037] The compression mechanism 2 is provided with a pressure-bearing component 8, the pressure-bearing component 8 is provided with a connecting component 9, the connecting component 9 is provided with a control component 10 connected with the lower connecting component 7, the control component 10 is used to control the gas flow of the lower connecting component 7, and a balancing component 11 is connected between the pressure-bearing component 8 and the upper connecting component 6;

[0038] Among them, when the air pressure of the upper connecting component 6 is greater than the air pressure of the lower connecting component 7, the air intake amount of the air intake regulating component 5 is reduced; when the air pressure of the upper connecting component 6 is less than the air pressure of the lower connecting component 7, the air intake amount of the air intake regulating component 5 is increased.

[0039] Working principle: When compressing air, the air is transported to the compression mechanism 2 through the air intake regulating component 5, and the driving mechanism 4 is used to drive the compression mechanism 2 to reciprocate back and forth, so that the compression mechanism 2 continuously compresses the air until the air is compressed to the required pressure, so that the air is released into the air storage cylinder 3 for storage or supplied to the working equipment. The compression mechanism 2 continuously moves back and forth and the air is continuously introduced, and compressed air is continuously generated; when the compression mechanism 2 detects that its own pressure is too high when it is compressed to the required position, it is necessary to adjust the air intake volume at this time, and the compressed gas in the air storage cylinder 3 is introduced into the air intake regulating component 5 through the upper connecting component 6, and is used The lower connecting component 7 guides the compressed gas to another position of the intake regulating component 5. The intake regulating component 5 is adjusted through the interaction between the upper connecting component 6 and the lower connecting component 7. Since the compression mechanism 2 generates pressure during the compression process, the pressure-bearing component 8 generates a balanced state under the action of the balancing component 11 and the pressure-bearing component 8 itself. When the pressure is too large, the overpressure will cause the pressure-bearing component 8 to move, and the connecting component 9 will rotate, forcing the control component 10 to move, thereby blocking the lower connecting component 7. In a unit time, the pressure of the upper connecting component 6 will be greater than that of the lower connecting component 7, thereby adjusting the intake regulating component 5 to reduce the air Intake volume, when air is introduced into the compression mechanism 2 and the air is compressed to the required position, the pressure will decrease until the pressure is adjusted to a reasonable range; when the compression mechanism 2 detects that its own pressure is too low when compressed to the required position, the pressure-bearing component 8 does not act due to the low pressure. At this time, the upper connecting component 6 is disconnected and the lower connecting component 7 is connected, so that the intake regulating component 5 increases the air intake volume, thereby increasing the intake volume in the compression mechanism 2, increasing the compressed air pressure value, and continuously adjusting the pressure in the compression mechanism 2 to be within a reasonable pressure range; in summary, the present application provides an air compressor intake volume regulating device that can utilize the compression in the air storage cylinder 3 to adjust the air intake volume. The standard pressure of the air is achieved by utilizing the actual pressure of the compressed air of the compression mechanism 2 to realize different adjustment degrees of the upper connecting component 6 and the lower connecting component 7, so as to realize the purpose of regulating and controlling the intake amount of the air intake regulating component 5, thereby adjusting the compressed air intake amount of the compression mechanism 2, realizing the adjustment effect of the air pressure in the compression mechanism 2, and realizing the feedback effect of the pressure, so that the device continuously generates compressed air within a reasonable pressure range, which is beneficial to the air pressure balance of the air compressor, and is beneficial to realizing the dynamic adjustment of the intake amount, so that the air compressor can work normally, improve the compression efficiency of the air compressor, and increase the service life of the air compressor.

[0048] like Figure 4 , Figure 5 , Figure 8 and Fig.10 As shown, an air compressor intake volume regulating device of the present invention, the connecting assembly 9 includes a connecting rod 901 arranged on the push rod 803, a spur rack 902 is arranged on the connecting rod 901, and a rotating gear 903 meshing with the spur rack 902 is fixedly sleeved on the rotating rod 1001.

[0049] like Figure 4 , Figure 5 and Figure 8 As shown, an air compressor intake volume regulating device of the present invention, the balancing component 11 includes a balancing pipe 1101 arranged on a connecting block 601, the balancing pipe 1101 is connected to a pressure cylinder 801, a solenoid valve four 1102 is installed on the balancing pipe 1101, and a one-way valve three 1103 is installed on the balancing pipe 1101.

[0050] Working principle: before compressing the air, open the control valve of the air intake pipe 502 to allow air to pass into the air intake pipe 502 and guide the air into the air intake cylinder 501. Since the air intake cylinder 501 is connected with the compression cylinder 201, the air continuously enters the compression cylinder 201. When compressing the air, start the motor 402, the output shaft of the motor 402 rotates to drive the cam 403 to rotate, and the rotation of the cam 403 drives the shaft 404 to rotate, so that the connecting rod 405 continuously reciprocates, the connecting rod 405 drives the compression rod 203 to move back and forth, and the compression rod 203 drives the compression piston 202 to continuously reciprocate. When the compression piston 202 is farthest from the motor 402, the compression piston 202 just compresses the air in the compression cylinder 201 to a reasonable pressure value. The air guide pipe 204 and the control valve are used to release the compressed air into the air storage cylinder 3 for storage or supply to the working equipment. The compression piston 202 continuously moves back and forth and the air continuously passes into the compression cylinder 201, and compressed air is continuously generated.

[0051] When the compression piston 202 moves to the farthest end from the motor 402, the pressure gauge 205 in the compression cylinder 201 detects that the pressure value in the compression cylinder 201 is too large or too small, and the air intake needs to be adjusted;

[0052] Open the electromagnetic valve four 1102 and the one-way valve three 1103, close the electromagnetic valve one 603, and force the compressed air of the standard pressure in the air storage cylinder 3 to enter the pressure cylinder 801, so that the pressure in the pressure cylinder 801 increases, so that the pushing piston 802 moves downward, and the pushing piston 802 drives the pushing rod 803 to move downward, until the pushing piston 802 is located at the limit block 805, and the limit block 805 limits the movement of the pushing piston 802. At this time, the spring 804 is stretched to a reasonable position. At this time, the electromagnetic valve four 1102 and the one-way valve three 1103 are closed to achieve a balancing effect of pushing the piston 802. When the pressure is too small, the compressed air pressure value in the compression cylinder 201 is less than the pressure in the air storage cylinder 3, that is, the pressure value in the compression cylinder 201 is less than the pressure value in the force cylinder, and the pushing piston 802 will not move at this time, but when the pressure value in the compression cylinder 201 is too large, the pushing piston 802 will move;

[0053] When the pressure in the compression cylinder 201 is too high, the excessive pressure drives the push piston 802 to move, and the push piston 802 drives the push rod 803 to move upward, and the push rod 803 drives the connecting rod 901 to move, so that the spur rack 902 moves, the spur rack 902 drives the rotating gear 903 to rotate, the rotating gear 903 drives the rotating rod 1001 to rotate, and the rotating rod 1001 drives the baffle 1002 to deflect at an angle, thereby generating an obstruction to the lower connecting pipe 701. Due to the provision of the air vent 1003, the ventilation function of the lower connecting pipe 701 will not be completely obstructed;

[0054] Open solenoid valve 1 603, solenoid valve 2 604, solenoid valve 3 702, check valve 1 605 and check valve 2 703, close solenoid valve 4 1102 and check valve 3 1103, so that the compressed air in the air storage cylinder 3 enters the upper connecting pipe 602 and the lower connecting pipe 701 respectively and simultaneously. When entering the upper connecting pipe 602, the compressed air will quickly enter the air inlet cylinder 501, so that the compressed air passes between the regulating piston 505 and the air inlet cylinder 501. When entering the lower connecting pipe 701, the compressed air is hindered by the baffle 1002, so that the speed of the compressed air entering the air inlet cylinder 501 is slowed down, so that the compressed air passes between the regulating piston 505 and the partition 503. In unit time, the pressure in the upper part of the air inlet cylinder 501 is greater than the pressure value in the lower part, so that the regulating piston 505 moves to the required adjustment position, and the regulating piston 505 drives the regulating rod 504 to move downward, and the regulating rod 504 drives the regulating diaphragm 506 to move downward. After the regulating diaphragm 506 moves downward, the intake opening of the intake pipe 502 will be reduced, thereby reducing the air intake amount entering the compression cylinder 201. The positional relationship between the intake pipe 502 and the regulating diaphragm 506 is explained. The regulating diaphragm 506 is located at the pipe mouth of the intake pipe 502. When the air passes through, the regulating diaphragm 506 divides the air into two parts. The upper part of the air will circulate between the regulating diaphragm 506 and the partition plate 503 and then be introduced into the intake pipe 502 again, while the lower part of the air will be introduced into the compression cylinder 201 through the intake cylinder 501, that is, the lower part of the air is the air intake amount. At this time, when the air enters the compression cylinder 201 and is compressed to the required position, the pressure will decrease until the pressure is adjusted to a reasonable range.

[0055] On the other hand, when the compressed air pressure in the compression cylinder 201 is greater, the pushing piston 802 moves more, forcing the pushing rod 803 to move more, causing the spur rack 902 to move more, forcing the rotating gear 903 to rotate more, causing the rotating rod 1001 and the baffle 1002 to rotate more, forcing the obstruction to be stronger, resulting in a greater pressure difference on both sides of the regulating piston 505, so that the regulating piston 505 moves more downward, the opening of the intake pipe 502 becomes smaller, and the air intake volume becomes smaller;

[0056] When the pressure gauge 205 detects that the compression piston 202 is compressed to the required position, its own pressure is too low. Since the pressure is too low, that is, the pressure value in the compression cylinder 201 is less than the pressure value in the force cylinder, the piston 802 does not move, so that the connecting component 9 and the control component 10 do not move. At this time, the solenoid valve 2 604, the one-way valve 1 605, the solenoid valve 4 1102 and the one-way valve 3 1103 are closed, and the solenoid valve 1 603, the solenoid valve 3 702, and the one-way valve 2 703 are opened, forcing the upper connecting pipe 602 to close and the lower connecting pipe 701 to connect. At this time, the compressed air passes through the lower connecting pipe 701. Tube 701 passes gas into the space between partition 503 and regulating piston 505, so that the pressure increases. Since the pressure value between regulating piston 505 and intake cylinder 501 remains unchanged, regulating piston 505 moves upward for a certain distance, forcing regulating piston 505 to drive regulating rod 504 to move upward, and regulating rod 504 drives regulating diaphragm 506 to move upward, which will increase the intake opening of intake pipe 502, thereby increasing the air intake amount entering compression cylinder 201, increasing the compressed air pressure value, and continuously adjusting the pressure in compression cylinder 201 to be within a reasonable pressure range.

[0057] The arrangement of the compression mechanism 2 enables the compression piston 202 to compress the air to a reasonable pressure value, and the air storage cylinder 3 is used for storage or use, and the pressure in the compression cylinder 201 is detected by the pressure gauge 205. When the pressure gauge 205 detects that the compressed gas pressure is too high or too low, the air intake volume is adjusted by the device, thereby achieving the control effect of the pressure of the compressed gas in the compression cylinder 201; the arrangement of the driving mechanism 4 can utilize the rotational force of the motor 402 to drive the connecting rod 405 to produce a reciprocating motion, thereby acting on the compression mechanism 2, so that the compression mechanism 2 produces a reciprocating motion force to achieve the compression effect on the air, and the symmetrical arrangement of the cam 403 can improve the stability of the device and facilitate the movement of the connecting rod 405 ; The setting of the air intake regulating component 5 can use the standard pressure value of the compressed air to adjust the position of the regulating diaphragm 506, thereby realizing the adjustment of the opening of the air intake pipe 502 and the adjustment of the air intake amount. The setting of the partition 503 can block the upper part of the air in the air intake pipe 502, so that the upper part of the air circulates and enters the air intake pipe 502; the setting of the upper connecting component 6 can introduce the compressed air into the upper part of the regulating piston 505 of the air intake cylinder 501. When the pressure is too high, the pressure value between the regulating piston 505 and the air intake cylinder 501 increases. When the pressure is too low, the pressure value between the regulating piston 505 and the air intake cylinder 501 remains unchanged, thereby realizing the adjustment of the regulating piston 505; the setting of the lower connecting component 7 can realize the compressed air The pressure of the air filter 502 is controlled by the pressure element 804. When the pressure is too high, the pressure between the air filter 502 and the air inlet cylinder 501 is greater than the pressure between the air filter 502 and the air inlet cylinder 501. When the pressure is too low, the pressure between the air filter 502 and the air inlet cylinder 501 is gradually increased. The pressure element 8 is configured to enable the push piston 802 to move. When the pressure is normal, the push force of the spring 804 and the pressure of the compressed air, as well as the limiting effect of the limit block 805, ensure the stability of the push piston 802. When the pressure is too high, the push piston 802 will move upward. When the pressure is too low, the push piston 802 will not move. The configuration of the connecting component 9 can transmit the force of the push rod 803, so that the control The control assembly 10 rotates, so that the control assembly 10 is located at different positions. The meshing action of the rotating gear 903 and the spur rack 902 allows the rotating rod 1001 to be stabilized at a certain position, thereby improving the stability of the control assembly 10 and the flexibility of the device. The setting of the control assembly 10 can achieve the blocking effect on the lower connecting pipe 701. When the pressure is too high, the greater the blocking effect on the lower connecting pipe 701, the less the amount of compressed air entering the lower connecting pipe 701, thereby making the pressure difference generated on both sides of the regulating piston 505 greater, thereby improving the control ability of the device. When the pressure is too low, the compressed air can enter smoothly. The setting of the air vent 1003 can prevent the baffle 1002 from completely blocking the entry of compressed air, thereby improving the rationality of the device.The setting of the balancing component 11 can introduce compressed air into the force-bearing cylinder to realize the clamping of the position of the push piston 802. When the compression cylinder 201 generates normal pressure, it will offset the air pressure in the force-bearing cylinder. At the same time, the spring 804 will generate a driving force to make the push piston 802 located at the limit block 805, so as to achieve the balance of the force of the push piston 802. When the pressure is too large, the spring 804 will move, so that the push piston 802 will move. When the pressure is too small, the driving force of the spring 804 and the pressure of the compressed air will make the push piston 802 not move, thereby improving the balancing function of the device. ;
