時間:2019-08-07點擊(ji)次(ci)數:1316

懸掛通過式拋(pao)丸(wan)機又稱懸鏈式拋(pao)丸(wan)機,在操作的(de)過程中有一些需要(yao)注意的(de)事項,小(xiao)編(bian)為您簡單介(jie)紹一下(xia)(xia),主要(yao)有以(yi)下(xia)(xia)幾點:

一、操作(zuo)者必須持(chi)證上(shang)崗、嚴禁無證操作(zuo),操作(zuo)前認真查閱設備交(jiao)接班(ban)記(ji)錄。

二、操(cao)作前維護及保養(yang):

1.檢(jian)查(cha)拋(pao)丸器(qi)及拋(pao)丸器(qi)電機上的固定螺栓有無松(song)動。

2.檢查拋(pao)丸(wan)器(qi)內葉(xie)片磨損(sun)情況,如果有磨損(sun)及時(shi)換;檢查拋(pao)丸(wan)器(qi)箱(xiang)體和拋(pao)丸(wan)器(qi)襯板、分丸(wan)輪、定(ding)向套、葉(xie)輪體是否過(guo)分磨損(sun)。

3.檢查拋丸(wan)室(shi)內護(hu)板的磨(mo)損情況(kuang),并及時換(huan)。

4.拋丸室內底護板:保持底護板清潔,無(wu)任(ren)何碎片。

5.檢查電流(liu)(liu)表,保證工作電流(liu)(liu)接近但不(bu)超過電機銘牌上(shang)的(de)電流(liu)(liu)額定值。

6.檢查(cha)各接近開關、指示燈(deng)的工(gong)作是(shi)否正(zheng)常。

7.檢查(cha)進(jin)出(chu)料門是(shi)否完全關閉。

8.除(chu)塵(chen)管道有無(wu)漏氣現象,除(chu)塵(chen)器中濾袋有無(wu)灰(hui)塵(chen)或破碎。

9.分(fen)離(li)器(qi)中過濾篩上有無積物。

10.氣控及電控閘閥(fa)是(shi)否關閉(bi)。

11.清掃電器(qi)控制箱上的灰塵。

三、手動操作方式:

1.工序(xu)(xu)啟(qi)(qi)動(dong)(dong)。該狀態(tai)下(xia)各(ge)機構(gou)均能實現單(dan)啟(qi)(qi)停(ting)(ting),在帶有負載(zai)運行時,應嚴格按工序(xu)(xu)啟(qi)(qi)停(ting)(ting),否則,可能引起(qi)堵(du)塞、飛塵等。操作如下(xia):首(shou)先合上(shang)(shang)斷路(lu)器(qi),用電源鑰匙把“關-電源-開(kai)”至開(kai)位(wei),電源燈亮。PLC上(shang)(shang)電,打“自動(dong)(dong)-手動(dong)(dong)”至手動(dong)(dong)位(wei),便可按按鈕逐個啟(qi)(qi)停(ting)(ting)、開(kai)閉各(ge)機構(gou)。啟(qi)(qi)停(ting)(ting)按鈕設為(wei)交(jiao)替型,即(ji)按一下(xia)啟(qi)(qi)動(dong)(dong),再按一下(xia)停(ting)(ting)止。請(qing)嚴格按以下(xia)順序(xu)(xu)啟(qi)(qi)停(ting)(ting)(每個電機間(jian)隔7-10秒):風機、反吹、分離器(qi)、提升(sheng)機、螺輸(shu)、拋(pao)丸(wan)器(qi)1、拋(pao)丸(wan)器(qi)2……拋(pao)丸(wan)器(qi)6、懸鏈啟(qi)(qi)動(dong)(dong)。

2.工件清(qing)理(li)。懸(xuan)鏈電源接(jie)通后(hou)便可開(kai)始(shi)進(jin)(jin)(jin)(jin)行預備拋(pao)丸工序(xu)。兩(liang)個小(xiao)車(che)(手動時(shi)也可進(jin)(jin)(jin)(jin)一(yi)個小(xiao)車(che))進(jin)(jin)(jin)(jin)入室體,到(dao)(dao)位后(hou),前(qian)后(hou)門(men)(men)(men)手動關(guan)閉(bi),當關(guan)到(dao)(dao)位后(hou)前(qian)后(hou)門(men)(men)(men)指示燈成(cheng)紅色。將“頂(ding)防(fang)(fang)護門(men)(men)(men)開(kai)、關(guan)”按(an)(an)一(yi)下(xia),頂(ding)防(fang)(fang)護門(men)(men)(men)進(jin)(jin)(jin)(jin),再將“自(zi)動進(jin)(jin)(jin)(jin)、退”按(an)(an)一(yi)下(xia),自(zi)轉機構(gou)進(jin)(jin)(jin)(jin)(同時(shi)自(zi)轉電機啟動),按(an)(an)一(yi)下(xia)“丸閘開(kai)、閉(bi)”扭,丸閘打(da)開(kai),拋(pao)丸計(ji)時(shi)器開(kai)始(shi)計(ji)時(shi),當時(shi)間到(dao)(dao)時(shi),丸閘關(guan)閉(bi);此時(shi)將“頂(ding)防(fang)(fang)護門(men)(men)(men)開(kai)、閉(bi)”按(an)(an)一(yi)下(xia),頂(ding)防(fang)(fang)護門(men)(men)(men)退,按(an)(an)“自(zi)轉進(jin)(jin)(jin)(jin)、退”自(zi)轉機構(gou)退,將“關(guan)-門(men)(men)(men)-開(kai)”旋(xuan)(xuan)鈕旋(xuan)(xuan)至開(kai)位,前(qian)后(hou)門(men)(men)(men)打(da)開(kai),開(kai)到(dao)(dao)位后(hou)指示燈成(cheng)綠(lv)色。拋(pao)丸停止器打(da)開(kai)兩(liang)次將小(xiao)車(che)開(kai)出(chu),清(qing)理(li)結束。

3.工序(xu)停止。逐個(ge)按停,順序(xu)與啟(qi)動時相反(fan)。

四、自動操作方式:

1.自(zi)動(dong)(dong)(dong)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong):首先合上空氣開關,把“關-電源-開”旋(xuan)至(zhi)開位(wei),打“手動(dong)(dong)(dong)/自(zi)動(dong)(dong)(dong)”扭至(zhi)自(zi)動(dong)(dong)(dong)位(wei),然后按下“自(zi)動(dong)(dong)(dong)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)”系統按以下程序啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong):風機啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、反吹啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、分(fen)離(li)器啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、提升機啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、螺輸(shu)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong),1#拋丸(wan)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、2#拋丸(wan)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)…6#拋丸(wan)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、自(zi)轉啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)、懸鏈啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong),整個啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)結(jie)束(shu)。

2.工件(jian)清(qing)理(li):首先吊(diao)取工件(jian)至小(xiao)(xiao)車(che)上,當小(xiao)(xiao)車(che)進(jin)入室體到(dao)位(wei)后(hou),頂(ding)防(fang)護(hu)(hu)門及(ji)自(zi)轉(zhuan)(zhuan)機構進(jin)到(dao)位(wei),丸閘打(da)開(kai),拋丸計時(shi)器開(kai)始計時(shi),當設置(zhi)的時(shi)間到(dao)時(shi),丸閘關閉,頂(ding)防(fang)護(hu)(hu)門退,自(zi)轉(zhuan)(zhuan)退,前門開(kai)、后(hou)門開(kai),將小(xiao)(xiao)車(che)自(zi)動開(kai)出(chu),工件(jian)清(qing)理(li)結束。

3.自(zi)動(dong)(dong)停(ting)(ting)止:當(dang)工(gong)件清(qing)理結(jie)束時,可按(an)自(zi)動(dong)(dong)停(ting)(ting)止按(an)鈕,自(zi)動(dong)(dong)燈閃爍,系(xi)統進入(ru)結(jie)束程序,按(an)如下程序逐步停(ting)(ting)止:拋丸(wan)器停(ting)(ting)止、懸鏈停(ting)(ting)、螺旋停(ting)(ting)、提升(sheng)機停(ting)(ting)、分離器停(ting)(ting)、風機、反(fan)吹停(ting)(ting),整(zheng)個(ge)系(xi)統工(gong)作(zuo)結(jie)束。

4.脈(mo)沖(chong)除塵控制:風(feng)機(ji)啟(qi)動后脈(mo)沖(chong)便自動循環,控制脈(mo)沖(chong)閥噴吹(chui)布袋上的(de)積(ji)塵,直至風(feng)機(ji)停止(zhi),便結(jie)束循環。
