一、自洗式攪拌器的(de)結構(gou)與原理(li)
自洗式攪拌器由控制(zhi)器(qi)(qi)、微型(xing)攪拌器(qi)(qi)、自(zi)動(dong)沖洗器(qi)(qi)、復合(he)電極、磁(ci)性傳感器(qi)(qi)和(he)電磁(ci)閥等部(bu)件構成。
(一(yi))控制器
控(kong)制器是的(de)控(kong)制中心,主要起供電(dian)(dian)和控(kong)制沖洗器(qi)的(de)動作等功能。當打開(kai)控(kong)制器(qi)電(dian)(dian)源時,面板上(shang)的(de)電(dian)(dian)源指示燈點(dian)亮,同(tong)時,攪(jiao)拌(ban)電(dian)(dian)機開(kai)始工作(攪(jiao)拌(ban)指示燈亮)。當微型攪(jiao)拌(ban)器(qi)置(zhi)于沖洗器(qi)上(shang)時,沖洗器(qi)上(shang)的(de)傳感器(qi)會(hui)感應到信號,此時控(kong)制器(qi)會(hui)自(zi)動打開(kai)電(dian)(dian)磁閥的(de)電(dian)(dian)源,沖洗器(qi)自(zi)動噴水,以清(qing)洗電(dian)(dian)極和攪(jiao)拌(ban)葉片。
(二)微型攪拌器
微型(xing)攪(jiao)拌器(qi)的結構與工作原理,主要由攪(jiao)拌電機(ji)和電極(ji)支架(jia)組成,使用時,攪(jiao)拌電機(ji)帶動(dong)攪(jiao)拌葉片,攪(jiao)動(dong)土壤溶液,以利于上(shang)部復合電極(ji)能(neng)盡快平衡。
(三)自動沖洗(xi)器(qi)
自(zi)動沖洗(xi)器由沖洗(xi)池(chi)、電(dian)磁(ci)(ci)(ci)(ci)閥、磁(ci)(ci)(ci)(ci)性傳(chuan)感器等組成。主要(yao)功能是自(zi)動清(qing)洗(xi)攪(jiao)(jiao)拌(ban)(ban)葉(xie)片和電(dian)極,同(tong)時(shi)也起(qi)微(wei)型攪(jiao)(jiao)拌(ban)(ban)器置定(ding)支架(jia)的(de)(de)作用。其(qi)(qi)工作原理是:當微(wei)型攪(jiao)(jiao)拌(ban)(ban)器置 于其(qi)(qi)上(shang)時(shi),攪(jiao)(jiao)拌(ban)(ban)器上(shang)的(de)(de)感應磁(ci)(ci)(ci)(ci)鐵(tie)與沖洗(xi)器上(shang)的(de)(de)傳(chuan)感器相(xiang)對(dui),此時(shi),通(tong)過(guo)控制(zhi)器,打(da)開(kai)電(dian)磁(ci)(ci)(ci)(ci)閥,帶(dai)有(you)壓力的(de)(de)純水通(tong)過(guo)噴水孔噴淋到(dao)電(dian)極和攪(jiao)(jiao)拌(ban)(ban)葉(xie)片上(shang),起(qi)到(dao)清(qing)洗(xi)作用,清(qing)洗(xi)時(shi),
攪(jiao)拌電(dian)(dian)機處(chu)于工作狀態,使清洗更加充分。 當微(wei)型攪(jiao)拌器離開自動沖(chong)洗器后,傳(chuan)感(gan)(gan)器則會(hui)即時(shi)感(gan)(gan)應,并通過控(kong)制器,關(guan)(guan)閉電(dian)(dian)磁閥,切(qie)斷水(shui)源(yuan),自動沖(chong)洗器則不再(zai)噴水(shui),以節約用(yong)水(shui)。注意(yi),當控(kong)制器處(chu)于關(guan)(guan)閉狀態時(shi),電(dian)(dian)磁閥處(chu)于關(guan)(guan)斷狀態,不會(hui)有(you)水(shui)噴出。這里指(zhi)出,自動沖(chong)洗器上所接的純水(shui)水(shui)源(yuan)必須有(you)0.2~0.4Mpa的壓力,當(dang)純水壓過低(di)時(shi), 清洗效(xiao)果變(bian)差(cha)。當純(chun)水(shui)壓力過(guo)大時,電(dian)磁閥將不能有效(xiao)關閉,造成純(chun)水(shui)浪費。
二、自動沖洗(xi)攪拌(ban)器安裝與調試
的(de)安裝(zhuang)主要是自動沖(chong)洗器(qi)的(de)安裝(zhuang),安裝(zhuang)前先將實(shi)驗(yan)(yan)臺面(mian)(mian)上(shang)鉆一園孔,以利于下(xia)水(shui),然(ran)(ran)后將下(xia)水(shui)管(guan)(guan)通入實(shi)驗(yan)(yan)臺下(xia)面(mian)(mian),有條件時可(ke)直接(jie)接(jie)入地漏中,也可(ke)用水(shui)桶盛接(jie)下(xia)水(shui)。然(ran)(ran)后用螺(luo)釘(ding)將其固(gu)定在臺面(mian)(mian)上(shang)。電磁閥可(ke)接(jie)在實(shi)驗(yan)(yan)臺下(xia)面(mian)(mian),固(gu)定后將水(shui)管(guan)(guan)接(jie)后即可(ke)。
各(ge)部位(wei)的(de)(de)連接(jie),將攪拌(ban)電機、電磁閥和(he)傳感器(qi)(qi)和(he)插頭分(fen)別(bie)插入控(kong)制(zhi)器(qi)(qi)的(de)(de)相(xiang)應(ying)插孔中(zhong),注意控(kong)制(zhi)器(qi)(qi)與沖洗器(qi)(qi)要離開30cm以上,以免將(jiang)水淺(qian)在控制(zhi)器上。安裝完畢后,接通(tong)電源(yuan)(yuan),打開(kai)電源(yuan)(yuan)開(kai)關,攪拌(ban)電機轉動、電源(yuan)(yuan)指示(shi)燈(deng)和攪拌(ban)指示(shi)燈(deng)亮;將(jiang)微型(xing)攪拌(ban)器置于沖(chong)(chong)(chong)洗器上,沖(chong)(chong)(chong)洗指示(shi)燈(deng)亮,沖(chong)(chong)(chong)洗器有水噴出,管路(lu)無(wu)漏(lou)水現象,即安裝完畢。
三、故障排除
是全自(zi)動的(de)控制設備,在(zai)使(shi)用過程中的(de)故(gu)障主要有(you)以下(xia)幾方面:
① 攪(jiao)(jiao)拌(ban)器不工作:產生這(zhe)種原因可從(cong)以下幾方面判斷,*,打開電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan),電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示(shi)燈不和攪(jiao)(jiao)拌(ban)指(zhi)示(shi)燈不亮,是(shi)控制(zhi)(zhi)(zhi)器電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)故障,檢查控制(zhi)(zhi)(zhi)器電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan);第二,打開控制(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)后,電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示(shi)燈和攪(jiao)(jiao)拌(ban)指(zhi)示(shi)燈工作正常(chang),攪(jiao)(jiao)拌(ban)器不工作,此時檢查攪(jiao)(jiao)拌(ban)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)插頭,如(ru)果插頭正常(chang),則是(shi)攪(jiao)(jiao)拌(ban)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)故障,需更換攪(jiao)(jiao)拌(ban)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)。
② 沖(chong)洗(xi)(xi)器(qi)(qi)(qi)(qi)(qi)工(gong)作(zuo)不正常:產生(sheng)這(zhe)種故障(zhang)(zhang)主要有(you)幾種原因,可通過以下(xia)步驟檢查:*,打開電源(yuan)后,電源(yuan)指示燈(deng)和攪(jiao)拌(ban)指示燈(deng)工(gong)作(zuo)正常,但微型(xing)攪(jiao)拌(ban)器(qi)(qi)(qi)(qi)(qi)放在(zai)沖(chong)洗(xi)(xi)器(qi)(qi)(qi)(qi)(qi)上以后,不能沖(chong)水,且沖(chong)洗(xi)(xi)指示燈(deng)不亮,這(zhe)時可將(jiang)電磁(ci)閥(fa)插(cha)頭(tou)撥(bo)下(xia),插(cha)到(dao)攪(jiao)拌(ban)電機插(cha)孔中,如果(guo)(guo)不噴水,表明是(shi)電磁(ci)閥(fa)故障(zhang)(zhang),更換電磁(ci)閥(fa);當(dang)電磁(ci)閥(fa)沒(mei)問題時,沖(chong)洗(xi)(xi)器(qi)(qi)(qi)(qi)(qi)不正常工(gong)作(zuo)的(de)問題則會是(shi)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)或控制器(qi)(qi)(qi)(qi)(qi)故障(zhang)(zhang),檢查傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)的(de)方法是(shi)將(jiang)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)插(cha)頭(tou)撥(bo)下(xia)下(xia),用萬用表的(de)電阻擋(dang)測其電阻值(zhi),當(dang)微型(xing)攪(jiao)拌(ban)器(qi)(qi)(qi)(qi)(qi)放在(zai)沖(chong)洗(xi)(xi)器(qi)(qi)(qi)(qi)(qi)上以后,電阻值(zhi)基本歸零,拿下(xia)微型(xing)攪(jiao)拌(ban)器(qi)(qi)(qi)(qi)(qi)后,電阻值(zhi)變為無限大(da),說(shuo)明傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)正常,如果(guo)(guo)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)不正常,更換傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi);如果(guo)(guo)傳(chuan)(chuan)(chuan)感(gan)器(qi)(qi)(qi)(qi)(qi)正常,則故障(zhang)(zhang)出(chu)現在(zai)控制器(qi)(qi)(qi)(qi)(qi)。
③ 噴(pen)水不能關閉:主要是(shi)電(dian)磁閥(fa)被雜質填塞,閥(fa)體(ti)不能關閉所致(zhi),解(jie)決(jue)該(gai)故障的方法有兩種(zhong),一是(shi)拆開清洗電(dian)磁閥(fa),二是(shi)更換(huan)電(dian)磁閥(fa)。
