On July 18, 2014, the “12th Five-Year†National 863 Program “Technical Standards for Electric Vehicles and Parts†passed by the China Automotive Technology and Research Center and Dongfeng Motor Co., Ltd. participated in the acceptance test. . Relevant leaders of the Ministry of Science and Technology of the Ministry of Science and Technology attended the report and heard the report. Wu Zhixin, deputy director of the China National Automobile Center, attended the acceptance meeting. Wen Baozhong, assistant director of the center and director of the standards institute, reported the results of the project. This topic focuses on the standard strategic planning of electric vehicles in China and related vehicle and component standard requirements. It focuses on the development strategy of China's electric vehicle technology standards, the planning of medium and long-term standards, and the study of important standards for electric vehicles and key components. The group organized and revised a number of important standards for electric vehicles, and carried out a large number of standard research work on the safety of electric vehicles, battery safety and performance. The project carried out all-round exchanges and cooperation on international standards and regulations for electric vehicles, and submitted Chinese proposals to international organizations. At the demonstration meeting, the expert group believes that the four international standards and regulations for electric vehicles proposed by the research group have distinctive features. The "China Electric Vehicle Standardization Work Roadmap" comprehensively summarizes the standard history of electric vehicles in China and plans the future development direction of electric vehicle standards. . The participating experts agreed to pass the technical acceptance. Cylinder assembly accessories refer to all cylinder assembly parts except the piston rod, cylinder tube and tie rods (some cylinders do not have tie rods).

Cylinder assembly accessories include one front cover and one rear cover, one piston, two Y-type piston seals, one hard-wearing ring, one set of magnetic rings (some cylinders do not have magnetic rings), two cylinder seal O-rings, one piston rod sealing ring, one dustproof, two buffer caps, two buffer screws (with O-ring), one piston rod end thread, one piston fixing bolt, 8 fixing bolts, dustproof air inlet and outlet two caps, one piston rod end thread protection cover.Air Cylinder Tube.
Because the different application needs different strokes of air cylinders, for dealers and distributors, storing a large number of cylinders with fixed strokes will occupy a large amount of inventory funds.Pneumatic Cylinder Tube.
However, storing the Pneumatic Cylinder assembly parts can solve this problem very well. When requires different strokes and then temporarily assembling the cylinder accordingly.Air Cylinder Barrel.
Common cylinder assembly parts include DNC square cylinder series, ISO standard Metalwork series, SI Mickey Mouse type ISO 15552 cylinder series, SC and SU AirTac standard cylinder series, SDA compact cylinder series, and DSN, MA, MAL mini air cylinder series, etc. .
Matters needing attention when assembling the cylinder
For non-professional cylinder manufacturers, we do not recommend self-assembly to avoid problems caused by incorrectly assembling cylinders.
The following points need to be paid attention to when assembling an air cylinder by yourself:
â—† The inner edge of a pneumatic cylinder needs to be chamfered to facilitate the entry of the piston and sealing ring into the cylinder tube.
â—† Before assembling the piston and cylinder, lubricating grease must be applied to the inner wall of the cylinder to reduce the friction between the sealing ring and the inner wall of the air cylinder.Pneumatic Cylinder Barrel.
â—† The edge of the piston rod end also needs to be chamfered to reduce damage to dust and buffer seals.Pneumatic Cylinder.
â—† Because the end of the piston rod has external threads, special attention should be paid when assembling the piston rod and the front end cover. It is necessary to use the end of the piston rod without threads to pass through the gasket. Otherwise, the inner wall of the gasket is easily cut by the threads and resulting in an air leakage.
â—† For the installation of the tie rod cylinder, it is also necessary to pay attention to the position of the tie rod thread, so that there is enough thread space in the fixing bolts of the front and rear end covers to install the cylinder accessories such as CA, CB mounting brackets, FA/FB flange brackets.Cylinder Tube.
