As the working medium of aircraft pneumatic systems, accumulator systems, landing gears and emergency systems, compressed air is more commonly used in the aviation industry, and the demand is also large. Compressed air mainly relies on air compressors in production. The VF-1.25/200 air compressor currently used is a compressed air that is cooled and dehydrated to obtain dry and clean compressed air after the ambient air is compressed in four stages. The displacement of this type of compressor is 1.25m3/min, and the rated exhaust pressure is 20.0MPa. 1 Design Overview VF-1.25/200A pressure swing adsorption compressed air drying equipment is a four-station assistant, master student, research direction Designed for gas fluid equipment. For the VF-1.25/200 air compressor trailer, the product has high-pressure air dew point exceeding the standard, the control circuit is complicated, the maintenance and troubleshooting are difficult, and the improved design is based on the original model. By developing a new type of compressed air drying equipment with the advantages of no heat regeneration, simple operation, long switching period, etc., we strive to achieve the best effect with minimal changes to meet the high pressure cold air dew point requirements of the aircraft. Design of VF-1.25/200A pressure swing adsorption compressed air drying equipment 2.1 Design ideas (1) The molecular sieve is regarded as an equivalent uniform continuous medium, and its physical parameters do not change with the adsorption amount and temperature. (2) The gas in the bed can be regarded as an ideal gas. (3) The axial pressure loss along the bed is negligible. (Continued from page 22) 3 Conclusions This paper analyzes the leakage flow of the axial piston motor plunger pair, and uses the motor parameters of a certain model to calculate the impact of the clearance on the leakage flow. It is reasonable to choose a gap range of 0.020.03 mm. Finally, it is pointed out that the main factors affecting the fit clearance are the liquid pressure of temperature and high pressure oil, which provides a reference for the future design of plunger pair. Moto Double Iridium Spark Plug Our company was set up in 2002.We are using the advanced cold punch technology to produce spark plug which is similar to NGK and Champion technology.With such technology, the metal shell and ceramic are better protected the quality of the spark plug are more stable to get avoid from air leaking and broken.Our spark plug products are ranged into more than 100 models with an anual out put of 6 million pcs.
