汽車涂裝生產線

   汽車(che)涂裝(zhuang)(zhuang)生(sheng)產線涂裝(zhuang)(zhuang)工(gong)(gong)藝，一(yi)般(ban)可分為兩大部分：一(yi)是(shi)涂裝(zhuang)(zhuang)前金屬(shu)的(de)(de)表面(mian)(mian)處(chu)(chu)理(li)，也叫(jiao)前處(chu)(chu)理(li)技術;二是(shi)涂裝(zhuang)(zhuang)的(de)(de)施工(gong)(gong)工(gong)(gong)藝。表面(mian)(mian)處(chu)(chu)理(li)主要(yao)包括清除(chu)工(gong)(gong)件表面(mian)(mian)的(de)(de)油污、塵土、銹蝕、以及進(jin)行修補作業時舊涂料(liao)層的(de)(de)清除(chu)等，以改善(shan)工(gong)(gong)件的(de)(de)表面(mian)(mian)狀(zhuang)態。包括根據(ju)各種具體情(qing)況對工(gong)(gong)件表面(mian)(mian)進(jin)行機械(xie)加工(gong)(gong)和(he)化(hua)(hua)學處(chu)(chu)理(li)，如磷(lin)化(hua)(hua)、氧(yang)化(hua)(hua)和(he)鈍化(hua)(hua)處(chu)(chu)理(li)。

   工(gong)(gong)程機(ji)械(xie)防銹涂(tu)(tu)裝(zhuang)工(gong)(gong)藝一(yi)般可分為涂(tu)(tu)裝(zhuang)前表面(mian)處理(li)工(gong)(gong)藝和(he)防銹底(di)漆(qi)涂(tu)(tu)裝(zhuang)工(gong)(gong)藝。

   表(biao)(biao)面(mian)處理(li)是防(fang)(fang)銹(xiu)(xiu)涂(tu)裝(zhuang)的重要工(gong)(gong)(gong)序之一(yi)。工(gong)(gong)(gong)程機械(xie)(xie)防(fang)(fang)銹(xiu)(xiu)涂(tu)裝(zhuang)質量在很大程度(du)上(shang)(shang)取決于表(biao)(biao)面(mian)處理(li)的方(fang)式好壞(huai)。據英國帝(di)國化(hua)學公司介(jie)紹(shao)，涂(tu)層壽命受3方(fang)面(mian)因素制約(yue):表(biao)(biao)面(mian)處理(li)，占60%;涂(tu)裝(zhuang)施(shi)工(gong)(gong)(gong)，占25%;涂(tu)料本身(shen)質量，占15%。工(gong)(gong)(gong)程機械(xie)(xie)行(xing)業，不(bu)同零部(bu)件的表(biao)(biao)面(mian)處理(li)方(fang)式。機械(xie)(xie)清(qing)理(li)可有效去除工(gong)(gong)(gong)件上(shang)(shang)的鐵銹(xiu)(xiu)、焊(han)渣、氧化(hua)皮，消除焊(han)接應(ying)力(li)，增加防(fang)(fang)銹(xiu)(xiu)涂(tu)膜與金屬基體的結合力(li)，從而大大提(ti)高工(gong)(gong)(gong)程機械(xie)(xie)零部(bu)件的防(fang)(fang)銹(xiu)(xiu)質量。機械(xie)(xie)清(qing)理(li)標準要求達到(dao)(dao)的Sa2.5級(ji)。表(biao)(biao)面(mian)粗糙(cao)度(du)要達到(dao)(dao)防(fang)(fang)銹(xiu)(xiu)涂(tu)層厚度(du)的1/3。噴、拋(pao)丸(wan)所用鋼丸(wan)要達到(dao)(dao)GB6484要求。薄板沖(chong)壓件的表(biao)(biao)面(mian)處理(li)稱(cheng)一(yi)般(ban)用化(hua)學表(biao)(biao)面(mian)處理(li)。

流水線設備操作簡要

       1、電(dian)(dian)(dian)器操作簡要(yao)：流水線(xian)的(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)需要(yao)三相四(si)線(xian)，外面裝(zhuang)有總開關一(yi)個，（可用三相四(si)線(xian)四(si)極開關， 用開關只控制三相電(dian)(dian)(dian)源(yuan)(yuan)，零線(xian)直接(jie)(jie)，注意切(qie)不可將(jiang)第(di)二種接(jie)(jie)法的(de)(de)零線(xian)也經過另外一(yi)個開關）。配電(dian)(dian)(dian)箱的(de)(de)n接(jie)(jie)零線(xian)，a， b， c接(jie)(jie)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)三相電(dian)(dian)(dian)源(yuan)(yuan)，u， v， w接(jie)(jie)電(dian)(dian)(dian)動機，3，4接(jie)(jie)調(diao)速電(dian)(dian)(dian)機的(de)(de)f1， f2。5，6，粉末噴粉流水線(xian)，7接(jie)(jie)調(diao)速電(dian)(dian)(dian)機的(de)(de)u，v，w。

2、啟動(dong)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)的(de)(de)(de)方(fang)法：先接(jie)通電(dian)(dian)(dian)(dian)源，此(ci)時(shi)三盞(zhan)電(dian)(dian)(dian)(dian)源指示燈全部都(dou)會亮，證明三相電(dian)(dian)(dian)(dian)源已經到配電(dian)(dian)(dian)(dian)箱。此(ci)時(shi)可以按(an)(an)一下(xia)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)開(kai)的(de)(de)(de)藍(lan)(lan)(lan)色按(an)(an)鈕，噴(pen)粉(fen)(fen)流水(shui)線(xian)，就可啟動(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，假如不(bu)能啟動(dong)，可以打(da)開(kai)配電(dian)(dian)(dian)(dian)箱門，看一下(xia)一排的(de)(de)(de)第二個dz108開(kai)關，是否是紅(hong)(hong)的(de)(de)(de)長(chang)，藍(lan)(lan)(lan)的(de)(de)(de)短。如果不(bu)是將此(ci)藍(lan)(lan)(lan)色的(de)(de)(de)壓下(xia)去就可。電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)啟動(dong)后，然后打(da)開(kai)流水(shui)線(xian)調(diao)速(su)(su)(su)表(biao)的(de)(de)(de)開(kai)關，噴(pen)粉(fen)(fen)流水(shui)線(xian)價格，再將調(diao)速(su)(su)(su)表(biao)的(de)(de)(de)電(dian)(dian)(dian)(dian)位(wei)器慢慢向上調(diao)，使轉(zhuan)速(su)(su)(su)表(biao)達到想(xiang)要的(de)(de)(de)速(su)(su)(su)度。關機(ji)(ji)(ji)時(shi)先將調(diao)速(su)(su)(su)表(biao)的(de)(de)(de)電(dian)(dian)(dian)(dian)位(wei)器慢慢向下(xia)調(diao)到零，電(dian)(dian)(dian)(dian)泳噴(pen)粉(fen)(fen)流水(shui)線(xian)，然后關閉調(diao)速(su)(su)(su)表(biao)的(de)(de)(de)開(kai)關，再按(an)(an)一下(xia)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)關的(de)(de)(de)紅(hong)(hong)色按(an)(an)鈕，就可停(ting)止電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。后將總(zong)開(kai)關關閉。
