Highway and Motor Transport 1 Application of compressed air to remove rain on the windshield of the car Gao Weishi \ Chen Xiaochao 2 (1. School of Automotive Management, People's Liberation Army, Anhui èšŒåŸ 233011; 2. People's Liberation Army, Automobile Officer School, Anhui Province From the aspects of vehicle safety and economy, the solution of compressed air and rain is designed. The calculation and test prove that the scheme has good practicability and is suitable for existing automotive assembly applications.
In China, due to the influence of tropical and subtropical monsoon climates, summers are hot and rainy, especially in the 7th and the month, which are often affected by strong convective weather, and there are often typhoons, which lead to the technical performance of vehicles driving in the rain. The decline has been made and the security risks are extremely prominent. This article mainly discusses the issue of rain removal of automobile windshield.
1 problem analysis The driver knows that the rain wiper in the rain is sometimes not very easy to use, especially in heavy rain, the rain can not be completely scraped off in time, and sometimes even has a certain adverse effect, in the front of the wiper under the scraping force The formation of a layer of rain film on the wind glass is more hindering the line of sight and seriously affects driving safety. There is currently no effective solution to this.
The main reason for the above phenomenon is that there is too much rain on the front windshield during heavy rain and a rain film is formed between the glass and the wiper, which prevents the two from being well combined, causing too much rain on the windshield to affect the line of sight. Measures need to be taken to remove or reduce the rain on the windshield so that it does not affect the line of sight. To this end, this paper discusses the application of compressed air in the windshield of automobiles.
2 Design Concept 2.1 Equipment Connection Relationship As shown, the micro-air compressor and small gas storage tank (in series) are installed in the position of the original wiper motor and the transmission mechanism; one branch is installed in the inlet of the wet gas storage tank. Pressure limiting valve, when the compressed air pressure reaches 650 kPa, the pressure limiting valve is opened (to ensure the safety of the vehicle brake), the high pressure air coming out of the pressure limiting valve is led to the small gas storage tank inlet through the pipeline; Air bag outlet installation
We are the specialized and top manufacturers in China and We offer full set Sesame Proessing Plant solution. Whole Seed Cleaning Plant is from Pre-cleaning, Fine cleaning, Destining, Gravityseparating, Beans polishing,Seed coating, Last seed weighing and packing.
The Seed Cleaning & Processing Line is composed of several single machines. Base on different grain type and processing grain, we will suggest appropriate grain cleaning machines. These grain cleaning machines arecollocated freely. Between each machines, there are Bucket Elevator , Inclined Evator or other conveying equipment to link up.
Sesame Seed Cleaning & Processing Plant has followingadvantages:
Easy to setup, machines easyto move and can be placed freely.
Save labor, there are middleconveyors to transfer grain from one machine to another.
Effective and low cost, singlemachines compose a seed processing line improve the working performance. Lowproduction cost makes it hot sale.
Above flexibility andconvenience makes Seed Cleaning & Processing Plant makes it becoming hot sales item.
Seed Processing Line installationeffect and introduction.
This Grain Cleaning & Processing Plant iscomposed of 5XZC-5DX Seed Cleaner & Grader, 5XZ-5 Gravity Separator , DTY Bucket Elevator, 5BYX-5 Seed Coating Machine, and HLD-50 Bagging Scale System.
Working flow: The seeds arefed into 5XZC-5DX Seed Cleaner &grader first. Seed cleaner & grader will remove the dust, lightimpurity, oversize and undersize impurity before seed flow into 5XZ-5 gravity separator. During seeds cleaned by Gravity Separator, the seeds are separated by density difference. Thepartially eaten seeds, immature seeds, insect damaged seed, sick seeds, moldyseeds are separated from good healthy seeds. Then seeds go on being lifted by DTY Bucket Elevator, falling into the 5BYX-5 Seed Coating Machine. During the seed coating procedure, the chemical,fertilizer or other protective liquidity will be coated to seeds' surface andimprove seeds' germination rate. Finally seeds being transferred to Weighing Scale . Seeds will be weightedand packed to bags ready for sell.
