時間:2019-08-07點擊次數:1316

懸掛通過式(shi)拋丸(wan)機又稱懸鏈式(shi)拋丸(wan)機,在操作(zuo)的(de)過程中有一些需要注(zhu)意的(de)事項,小編為您(nin)簡單介紹一下(xia),主要有以下(xia)幾點:

一、操作(zuo)者必須持證上崗、嚴禁無證操作(zuo),操作(zuo)前認真(zhen)查閱設備交接班記(ji)錄。

二、操作前維護及保(bao)養(yang):

1.檢查拋(pao)丸(wan)器(qi)及拋(pao)丸(wan)器(qi)電機上的(de)固(gu)定螺栓有(you)無松動。

2.檢查拋丸器內(nei)葉片磨(mo)損(sun)情況,如果有磨(mo)損(sun)及時換;檢查拋丸器箱(xiang)體和拋丸器襯(chen)板、分(fen)丸輪(lun)(lun)、定向套(tao)、葉輪(lun)(lun)體是(shi)否過分(fen)磨(mo)損(sun)。

3.檢查拋丸室內護板的(de)磨損情況,并及時換。

4.拋丸(wan)室內底護板:保(bao)持底護板清(qing)潔(jie),無任何碎(sui)片(pian)。

5.檢(jian)查(cha)電流表(biao),保(bao)證(zheng)工作(zuo)電流接近但不(bu)超過(guo)電機(ji)銘牌上的電流額定(ding)值。

6.檢(jian)查各接近開(kai)關、指(zhi)示燈的工作是否(fou)正常。

7.檢查進出料門是否完全關閉。

8.除(chu)塵(chen)管(guan)道(dao)有無(wu)漏(lou)氣(qi)現象,除(chu)塵(chen)器中濾袋有無(wu)灰塵(chen)或破碎(sui)。

9.分離器中過濾(lv)篩上有無積物。

10.氣控(kong)及(ji)電(dian)控(kong)閘閥是(shi)否關閉。

11.清掃電(dian)器控制箱上的灰塵。

三、手動操作方式:

1.工序(xu)啟(qi)(qi)(qi)(qi)動(dong)(dong)。該狀(zhuang)態下(xia)(xia)各(ge)機(ji)構(gou)均能實現單啟(qi)(qi)(qi)(qi)停(ting)(ting),在(zai)帶有負載運行時,應嚴格按(an)工序(xu)啟(qi)(qi)(qi)(qi)停(ting)(ting),否則,可能引起堵塞、飛塵等。操作(zuo)如下(xia)(xia):首先合上(shang)斷路器(qi)(qi),用(yong)電(dian)源鑰匙把“關-電(dian)源-開(kai)”至開(kai)位(wei),電(dian)源燈亮。PLC上(shang)電(dian),打“自動(dong)(dong)-手動(dong)(dong)”至手動(dong)(dong)位(wei),便可按(an)按(an)鈕(niu)逐(zhu)個啟(qi)(qi)(qi)(qi)停(ting)(ting)、開(kai)閉各(ge)機(ji)構(gou)。啟(qi)(qi)(qi)(qi)停(ting)(ting)按(an)鈕(niu)設為(wei)交(jiao)替型(xing),即按(an)一下(xia)(xia)啟(qi)(qi)(qi)(qi)動(dong)(dong),再按(an)一下(xia)(xia)停(ting)(ting)止。請嚴格按(an)以下(xia)(xia)順序(xu)啟(qi)(qi)(qi)(qi)停(ting)(ting)(每(mei)個電(dian)機(ji)間隔7-10秒):風機(ji)、反吹、分離(li)器(qi)(qi)、提升機(ji)、螺輸、拋丸器(qi)(qi)1、拋丸器(qi)(qi)2……拋丸器(qi)(qi)6、懸鏈啟(qi)(qi)(qi)(qi)動(dong)(dong)。

2.工件清理。懸鏈電源接通(tong)后(hou)(hou)(hou)便(bian)可開(kai)(kai)始進(jin)行預備拋丸工序。兩(liang)個(ge)小(xiao)車(che)(手(shou)動(dong)(dong)時(shi)(shi)也可進(jin)一(yi)(yi)個(ge)小(xiao)車(che))進(jin)入(ru)室體(ti),到位(wei)后(hou)(hou)(hou),前后(hou)(hou)(hou)門(men)手(shou)動(dong)(dong)關閉(bi)(bi),當關到位(wei)后(hou)(hou)(hou)前后(hou)(hou)(hou)門(men)指(zhi)示燈成紅色(se)。將“頂防(fang)護門(men)開(kai)(kai)、關”按(an)(an)一(yi)(yi)下(xia),頂防(fang)護門(men)進(jin),再(zai)將“自(zi)動(dong)(dong)進(jin)、退(tui)”按(an)(an)一(yi)(yi)下(xia),自(zi)轉(zhuan)機(ji)構(gou)進(jin)(同時(shi)(shi)自(zi)轉(zhuan)電機(ji)啟動(dong)(dong)),按(an)(an)一(yi)(yi)下(xia)“丸閘開(kai)(kai)、閉(bi)(bi)”扭,丸閘打(da)(da)開(kai)(kai),拋丸計時(shi)(shi)器開(kai)(kai)始計時(shi)(shi),當時(shi)(shi)間到時(shi)(shi),丸閘關閉(bi)(bi);此時(shi)(shi)將“頂防(fang)護門(men)開(kai)(kai)、閉(bi)(bi)”按(an)(an)一(yi)(yi)下(xia),頂防(fang)護門(men)退(tui),按(an)(an)“自(zi)轉(zhuan)進(jin)、退(tui)”自(zi)轉(zhuan)機(ji)構(gou)退(tui),將“關-門(men)-開(kai)(kai)”旋鈕旋至開(kai)(kai)位(wei),前后(hou)(hou)(hou)門(men)打(da)(da)開(kai)(kai),開(kai)(kai)到位(wei)后(hou)(hou)(hou)指(zhi)示燈成綠色(se)。拋丸停(ting)止器打(da)(da)開(kai)(kai)兩(liang)次將小(xiao)車(che)開(kai)(kai)出,清理結束。

3.工序停止。逐個按停,順序與啟動(dong)時相反(fan)。

四、自動操作方式:

1.自動(dong)(dong)(dong)(dong)(dong)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong):首(shou)先合上空(kong)氣開關(guan),把“關(guan)-電(dian)源(yuan)-開”旋至開位,打(da)“手動(dong)(dong)(dong)(dong)(dong)/自動(dong)(dong)(dong)(dong)(dong)”扭(niu)至自動(dong)(dong)(dong)(dong)(dong)位,然(ran)后按(an)下(xia)(xia)“自動(dong)(dong)(dong)(dong)(dong)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)”系統按(an)以下(xia)(xia)程序啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong):風機啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、反吹(chui)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、分離器啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、提升機啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、螺輸啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong),1#拋丸(wan)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、2#拋丸(wan)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)…6#拋丸(wan)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、自轉(zhuan)啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)、懸鏈啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong),整個啟(qi)(qi)動(dong)(dong)(dong)(dong)(dong)結束。

2.工件(jian)清理:首先(xian)吊取工件(jian)至(zhi)小車上,當小車進入(ru)室體到位后(hou),頂防護(hu)(hu)門(men)(men)及自轉機構進到位,丸閘(zha)(zha)打(da)開(kai),拋丸計(ji)時(shi)器開(kai)始計(ji)時(shi),當設置的時(shi)間到時(shi),丸閘(zha)(zha)關閉(bi),頂防護(hu)(hu)門(men)(men)退,自轉退,前門(men)(men)開(kai)、后(hou)門(men)(men)開(kai),將小車自動開(kai)出,工件(jian)清理結(jie)束。

3.自動停(ting)(ting)止(zhi)(zhi)(zhi):當工(gong)件清理結(jie)(jie)束時,可(ke)按自動停(ting)(ting)止(zhi)(zhi)(zhi)按鈕,自動燈閃(shan)爍,系統進入結(jie)(jie)束程序,按如下(xia)程序逐步停(ting)(ting)止(zhi)(zhi)(zhi):拋(pao)丸(wan)器停(ting)(ting)止(zhi)(zhi)(zhi)、懸鏈(lian)停(ting)(ting)、螺(luo)旋停(ting)(ting)、提升機(ji)停(ting)(ting)、分離器停(ting)(ting)、風機(ji)、反吹停(ting)(ting),整個系統工(gong)作結(jie)(jie)束。

4.脈沖(chong)(chong)除塵控制(zhi):風機啟(qi)動后脈沖(chong)(chong)便自動循環,控制(zhi)脈沖(chong)(chong)閥(fa)噴吹布袋(dai)上的(de)積塵,直至風機停(ting)止(zhi),便結束循環。
