也可以減少膠輥膠圈的損壞和損傷,這也是棉紗質(zhì)量保持穩(wěn)定、減少棉紗疵點的重點。牽伸和卷繞部件隨著每天清潔次數(shù)的增加,飛花附入牽伸和卷繞部件的幾率降低,膠輥膠圈纏繞幾率下降,膠輥膠圈損傷、損壞的程度明顯下降;隨著紡紗號數(shù)的增加和棉紗質(zhì)量要求提高,膠輥膠圈纏繞、損傷、損壞的程度更加明顯,增加牽伸和卷繞部件的清潔頻次是行之有效的。在生產(chǎn)普通號數(shù)棉紗時,牽伸和卷繞部件每班清潔兩次膠輥膠圈的損傷、損壞只有牽伸和卷繞部件每天清潔一次的10%~20%。實踐證明,牽伸和卷繞部件合理的清潔頻次和適當(dāng)增加清潔頻次,是保證膠輥膠紡紗完整的重要環(huán)節(jié)。

style="text-indent:25px">軋輥能感生渦流的非金屬材料其主要優(yōu)點是能探測次表面缺陷以及能探測復(fù)合澆注軋輥的結(jié)合處的缺陷。一般說來，用耦合晶柱探頭對次表層探傷。為了使聲波有效地傳入軋輥要使用水（油）作為耦合劑。進(jìn)一步開發(fā)了表面波和切面波合成探頭，可能會代替渦流探傷。超聲波探傷原理：超聲波探傷是利用超聲波在物質(zhì)中的傳播、反射和衰減等物理特性來發(fā)現(xiàn)缺陷的一種探傷方法。超聲波探傷具有靈敏度高、探測速度快、成本低、操作方便、探測厚度大對人體和環(huán)境無害，特別對裂紋、未熔合等危險性缺陷探傷靈敏度高等優(yōu)點。上海軋輥廠家定制</p><p
