System performance According to the requirements of the national standard, the system automatically controls the speed of the air compressor and the outlet pressure of the secondary cylinder to make it possible to study the application of electronic technology. After collecting the data, the data processing such as table lookup and parameter calculation is automatically performed according to the requirements of the national standard, and the processed results are displayed, stored, and printed to complete the performance test under the first working condition. Then change the ambient temperature and perform the performance test under the second condition. After the test, the air compressor performance was automatically analyzed (manually designed mathematical analysis model) and the improvement scheme was proposed as a reference. The above process is completely completed under the control of the microcomputer, and the air compressor performance test is accurate, fast and intelligent. The system consists of a test system component block diagram consisting of an air compressor test device, a data acquisition and conversion device, a control execution device, and a microcomputer processing device. Air compressor test device air compressor test device schematic. System software design: Software block diagram software block diagram. Software Composition and Design Method The air compressor automatic test system software mainly consists of the following parts. The data acquisition and output control module completes the collection of more than a dozen parameters and the control of the rotational speed and differential pressure. It is designed and made into a dynamic connection library file in C language for other modules to call. The data processing module realizes the processing of the test data according to the requirements of the national standard. In the process of processing, the parameter values ​​to be tested are subjected to complicated processing such as table lookup and calculation, so the DLL file is still designed and made in C language. The data display module displays parameters such as speed, torque, temperature and pressure in real time, which can be displayed in digital or curved form. In order to achieve visualization, VB6.0 is designed. The printout module prints the test results in time and saves them as a hard copy. If necessary, it can be manually set to print out the previous historical test data. The performance analysis module analyzes the mathematical model according to the artificially established performance. Based on the measured air compressor performance parameters and the national standard requirements, the improved solution is proposed as a reference. The main module realizes friendly human-computer interaction interface. With 4 system features, the system fully complies with the technical specifications stipulated by GB3853 standard, and achieves the following performance after long-term operation.
Automotive plastic parts are components made of various plastics that are used in the manufacture and repair of vehicles. These parts are used in various areas of the vehicle, including the interior, exterior, engine, and more. They are favored for their light weight, low cost and versatility.Automobile Parts.
1. Instrument Panel: This is the control panel located directly in front of the driver of the vehicle that displays the instruments and controls for vehicle operation.
2. Headlight and Taillight Covers: These covers are often made of polycarbonate due to its high impact resistance and ability to be formed into complex shapes.
3. Seat Belts: Although seat belts are not entirely made of plastic, seat belts often use plastic parts for their buckles and adjustment mechanisms.Car Spare Parts.
4. Air filters: They are usually made of various types of plastic and are used to filter out harmful particles from the air before it enters the engine.
5. Engine parts: Many parts of the engine, such as valve covers, oil pans, intake manifolds, etc., can be made of plastic to reduce weight and cost.
6. Radiator Fans: These fans are usually made of plastic due to their heat resistance and light weight.
