Description

Technical Field

[0001] This application belongs to the technical field of air compressor flow measurement, and specifically relates to an air compressor flow measurement device. Background Art

[0002] An air compressor is a mechanical device that converts electrical energy or other forms of energy into compressed air. Compressed air is a high-pressure gas that can be used to power various tools, machines, and processes. Air compressors can be divided into piston type, rotary vane type, and screw type. These three types of air compressors all use centrifugal force to compress air into a storage tank. An air compressor flow measurement device is used to measure the flow rate of compressed air discharged by an air compressor, which is crucial for ensuring that the air compressor operates at optimal efficiency. Air compressors are widely used in industrial and commercial fields, including power tools, industrial machinery, spraying, cleaning, and medical applications. They provide an efficient and reliable source of compressed air that can be used for various tasks.

[0003] For example, in the utility model patent with the publication number CN220470180U, an automated air compressor gas flow detector is disclosed, which includes a first flange wheel. A plurality of grooves are formed on the outer side of the first flange wheel. A first gasket is fixedly installed on the outer side of the first flange wheel. A first pipe is arranged on the outer side of the first flange wheel. A second flange wheel is fixedly installed on the outer side of the first pipe. A second gasket is fixedly installed on the outer side of the second flange wheel. The gaskets, the first rubber ring, and the second rubber ring provided in the present utility model perform multiple seals on the overall detector, thereby avoiding gas leakage and affecting the detection data. The provided runner can rotate the ball valve, thereby facilitating the adjustment of the gas flow rate. The second flange wheel is adapted to the fixed column. When the first pipe is damaged, the fixed column is rotated to quickly replace the first flange wheel and the first pipe, and the device has strong practicability.

[0004] However, it is found in the actual use process that: the device cooperates with a second rotating shaft and a rotating plate, so that when the gas is discharged, the rotating plate can be pushed to rotate, and the overall flow rate can be calculated according to the number of rotations of the rotating plate.

[0005] However, a plurality of rotating plates are installed on the device. In this way, when the gas is discharged through the air outlet box, the rotating plates will increase the fluid resistance, resulting in a pressure drop and a decrease in the flow rate. Moreover, the installation of the rotating shaft and the rotating plate needs to be selected at a suitable position to minimize the impact on the flow rate. In this way, the overall adaptability is poor. Therefore, an air compressor flow measurement device is provided. Utility Model Content

A mounting bracket is fixedly installed on the top surface of the gas storage tank. A driving motor is fixedly installed on the top surface of the mounting bracket.

[0008] In a preferred embodiment, a rubber sealing ring is fixedly installed on the inner wall surface of the circular through-hole. The detection end of the proximity switch passes through the middle of the rubber sealing ring. The outer surface of the proximity switch is threadedly connected with a sealing pressing plate. The sealing pressing plate is fixedly installed on the outer surface of the cylinder block through the provided bolts.

[0009] In a preferred embodiment, a connecting pipe is fixedly installed on the outer surface of the gas storage tank near the top. One end of the connecting pipe away from the gas storage tank is fixed to the exhaust pipe installed on the outer surface of the cylinder block.

[0010] In a preferred embodiment, an air outlet pipe is fixedly installed at the front end of the gas storage tank. A connecting pipe is fixedly installed at the front end of the air outlet pipe. A manual valve is fixedly installed on the outer surface of the connecting pipe.

[0012] In a preferred embodiment, two tank supports are fixedly installed on the bottom surface of the gas storage tank. Installation holes are formed in the inner bottom surfaces of the two tank supports.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned solution, the driving motor drives the main shaft and the blades inside the cylinder block to rotate, enabling the outside air to enter the inside of the cylinder block. At this time, the gap between the rotating blades and the cylinder block compresses the air, and the compressed air enters the inside of the gas storage tank through the connecting pipe for storage. After the main shaft rotates one circle, the iron sheet will touch the proximity switch once, which will cause the proximity switch to continuously generate pulse signals. These signals are fed back to the flow controller, and the flow controller analyzes the pulse signals through internal components to calculate the rotational speed of the main shaft. Since the rotational speed of the main shaft of the vane air compressor is linearly related to the flow rate, the flow rate generated by the air compressor can be calculated based on the rotational speed of the main shaft and displayed on the display screen of the flow controller. In this way, the flow rate can be deduced after detecting the rotational speed of the main shaft, facilitating the measurement of the flow rate. Using this method not only has a stable structure, is convenient for maintenance and installation, but also can effectively reduce the impact on the flow rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The implementation principle of an embodiment of the air compressor flow measurement device of this application is as follows: First, the operator installs the proximity switch 10 on the sensor bracket 9 and makes its bottom end extend through the middle of the rubber sealing ring 12 into the inside of the cylinder block 4. When the detection end of the proximity switch 10 enters the inside of the cylinder block 4, the proximity switch 10 approaches the iron sheet 7. At this time, the operator fixes the sealing pressing plate 13 to the outer surface of the cylinder block 4 through bolts to fix the rubber sealing ring 12. In this way, when the cylinder block 4 subsequently compresses the gas, the gas will not leak;

[0031] When the driving motor 3 drives the main shaft 5 and the blades inside the cylinder block 4 to rotate, the outside gas will enter the inside of the cylinder block 4 through the intake pipe installed on the front side of the cylinder block 4. At this time, the gap between the rotating blades and the cylinder block 4 compresses the gas. The compressed gas enters the inside of the gas storage tank 1 through the connecting pipe 14 for storage. After the main shaft 5 rotates one circle, the iron sheet 7 will contact the proximity switch 10 once, which will cause the proximity switch 10 to continuously generate a pulse signal. This signal is fed back to the flow controller 11. The flow controller 11 analyzes the pulse signal through internal components (such as microcontrollers, application-specific integrated circuits, etc.) to calculate the rotation speed of the main shaft 5. Since the rotation speed of the main shaft 5 of the vane type air compressor is linearly related to the flow rate, the flow rate generated by the air compressor can be calculated according to the rotation speed of the main shaft 5 and displayed on the display screen of the flow controller 11. In this way, the flow rate generated by the air compressor can be conveniently measured. The device has a simple structure and convenient operation. Due to the linear relationship between the rotation speed of the vane type air compressor and the flow rate, the flow rate can be deduced after detecting the rotation speed of the main shaft 5, so as to facilitate the measurement of the flow rate. Using this method not only has a stable structure, is convenient for maintenance and installation, but also can effectively reduce the influence on the flow rate.
