阀片是空气压缩机易损件之一,承受小能量多次冲击载荷,对翘曲变形要求甚高。曾经有人做过试验,某种阀片当翘曲度由0.02～0.03毫米增高到0.06毫米,其他条件不变时,则压缩机的气量下降10％。另外,阀片经淬火回火后,因翘曲变形需冷校平,这使其疲劳强度也有所下降。可见阀片的翘曲度大小直接影响空气压缩机的使用性能和本身的寿命。很多工厂目前对阀片淬火回火后的翘曲变形和椭圆变形有解决,所以淬火回火后对于翘曲度和椭
Valve is one of the vulnerable parts of air compressor, withstand small impact energy load, the warping deformation of very demanding. Someone once had a test, a valve when the warpage from 0.02 to 0.03 mm increased to 0.06 mm, other conditions remain unchanged, the compressor gas volume decreased by 10%. In addition, the valve after quenching and tempering, warping deformation due to cold leveling, which makes its fatigue strength also declined. Visible warp valve size directly affects the performance of air compressors and their life expectancy. Many factories are currently on the valve after the quenching and tempering warpage deformation and elliptical deformation are resolved, so the quenching and tempering for warpage and elliptical
