在阀簧和阀片上的撞击速度,是影响其寿命的重要原因。按此观点导出了参数ωh和(ρf.pd)/(mω),提出了计算升程的经验公式:h=h’-Δh, 将此公式用于某些压缩机气阀的改进工作,取得了良好的效果。
The impact velocity on the valve spring and the valve plate is the important reason that affects its life span. From this point of view, the parameter ωh and (ρf.pd) / (mω) are derived and the empirical formula for calculating the lift is proposed: h = h’-Δh. This formula is used to improve some compressor valves and obtain Good effect.
