膠輥?zhàn)鳛橹匾臓可煸湫阅?、管理水平都與成紗質(zhì)量密切相關(guān)。使用廠家不僅要注重其制作工藝及磨礪精度，膠輥的后續(xù)使用、管理與維護(hù)對(duì)確保膠輥紡紗性能的優(yōu)良及穩(wěn)定也非常重要，二者應(yīng)相輔相成才能達(dá)到穩(wěn)定的紡紗質(zhì)量水平。我們本著“認(rèn)真選型、嚴(yán)把質(zhì)量、精細(xì)制作、分區(qū)管理、以國(guó)產(chǎn)逐步替代進(jìn)口”的原則，對(duì)膠輥進(jìn)行全過(guò)程管理。 </p> <p> <br /> </p> <p> 批量購(gòu)進(jìn)膠管（包括新品膠管或者選擇新的膠管制造廠家）前，要對(duì)所選膠管型號(hào)、規(guī)格、性能、紡紗質(zhì)量做到心中有數(shù)，具體做法是： </p> <p> 1）由于現(xiàn)在全國(guó)制造膠管的廠家眾多、品種繁雜，因此首先要對(duì)制造廠家進(jìn)行了解； </p> <p> 2）膠管硬度從邵爾A60度～90度不等，因此在購(gòu)進(jìn)膠管前要清楚制造廠家的制造工藝流程，對(duì)生產(chǎn)廠家的設(shè)備狀態(tài)及技術(shù)水平有一定的認(rèn)識(shí)； </p> <p> 3）進(jìn)行小批量試驗(yàn)，在成紗質(zhì)量穩(wěn)定的前提下進(jìn)行中試； </p> <p> 4）大面積購(gòu)進(jìn)時(shí)，至少要進(jìn)行一個(gè)車位的試驗(yàn)，以多方面了解其生活波動(dòng)、試紡性能以及品種適用性，并要經(jīng)不同季節(jié)（尤其是高溫、高濕季節(jié)）的車上運(yùn)轉(zhuǎn)，考驗(yàn)?zāi)z輥的抗繞花性、耐磨性，彈性恢復(fù)以及對(duì)化學(xué)涂料的滲透性能等，試驗(yàn)合格后，方可進(jìn)行大面積推廣。

膠輥軸承和羅拉軸承的清洗、加油對(duì)膠輥膠圈的影響在紡織廠不容易引起重視。通常膠輥軸承加油都是隨手任意往上涂,沒(méi)有量的控制,保全保養(yǎng)時(shí)和三班機(jī)修工也都在過(guò)量給羅拉軸承加油,從而造成膠輥軸承在運(yùn)轉(zhuǎn)過(guò)程中溢出,油污浸入膠輥或膠圈的表面或內(nèi)部,導(dǎo)致膠輥膠圈在運(yùn)動(dòng)過(guò)程中老化龜裂,從而造成大量纏繞和損壞、損傷。即使紡紗廠加強(qiáng)膠輥膠圈的清潔,也很難對(duì)已經(jīng)浸透在膠輥膠圈內(nèi)的油污清潔干凈,從而影響運(yùn)轉(zhuǎn)效率,這也是棉紗產(chǎn)生油污、疵點(diǎn)的主要因素。改進(jìn)膠輥軸承的加油方式、控制加油量是保護(hù)膠輥膠圈不被腐蝕、浸透、損傷、損壞的因素之一。羅拉軸承加油的油脂型號(hào)、加油量的多少、加油機(jī)的擠壓次數(shù)是減少膠輥膠圈污染、損傷、損壞、龜裂、破裂的關(guān)鍵。因此對(duì)不同的紡紗設(shè)備羅拉軸承必須采用不同的油脂型號(hào)和加油方式加油,嚴(yán)格控制加油量,加油后的膠輥、羅拉軸承在運(yùn)行24h之內(nèi)無(wú)油污溢出是比較好的加油效果。如果膠輥、羅拉軸承在運(yùn)動(dòng)過(guò)程中有少量的油污溢出,必須迅速處理干凈,防止油污對(duì)羅拉、膠輥膠圈的污染,影響紡紗效果和紡紗質(zhì)量。上海擠干輥采購(gòu)</p></p><br
