Self- sustained Oscillation Pulsed Air Blowing System for Energy Saving
energy saving pulse blowing self-sustained oscillation pneumatic power
2011/8/3
Currently, many studies have been made for years on dimensions of pneumatic nozzle, which influence the flow characteristic of blowing system. For the purpose of outputting the same blowing force, the...
Effect of Air-blowing Variables on Bond Strength of All-in-one Adhesives to Bovine Dentin
Air-blowing All-in-one adhesives Microtensile bond strength
2009/9/15
This study evaluated the effect of air-blowing variables on the microtensile bond strength (μTBS) of two all-in-one adhesives. A bonding agent was applied to the flat dentin surface of extracted bovin...
加压条件下气力轮式精密排种器性能分析（Analysis on Performance of an Air-blowing Vertical-rotor Type Precision Seed-metering Device）
排种器 性能 加压条件
2009/8/11
针对研制的气力轮式精密排种器，采用均匀设计法设计试验，运用均匀设计软件UST 1.0建立了大豆排种性能指标数学模型，分析气力条件下排种器设计参数对排种性能的影响规律。分析表明：气力条件下，排种性能指标主要受气压和作业速度影响，气压范围为1.4～1.8kPa时粒距合格率达到85%以上，满足8?km/h速度以上大豆精密播种；充种角和清种角变化对排种性能影响不显著，充种角和清种角优化区域与常压条件下排种...
