高溫齒輪泵結(jié)構(gòu)及工作原理
一臺(tái)完整的高溫齒輪泵包括馬達(dá)、減速器、聯(lián)軸器和泵頭幾部分,泵頭部分由泵殼、前后側(cè)蓋、齒輪軸、滑動(dòng)軸承和軸封構(gòu)成。高溫齒輪泵屬于正位移泵,工作時(shí)依靠主、從動(dòng)齒輪的相互嚙合造成的工作容積變化來輸送熔體。工作容積由泵體、齒輪的齒槽及具有側(cè)板功能的軸承構(gòu)成。
當(dāng)齒輪旋轉(zhuǎn)時(shí),熔體即進(jìn)入吸入腔兩齒輪的齒槽中,隨著齒輪轉(zhuǎn)動(dòng),熔體從兩側(cè)被帶入排出腔,齒輪的再度嚙合,使齒槽中的熔體被擠出排出腔,壓送到出口管道。只要泵軸轉(zhuǎn)動(dòng),齒輪就向出口側(cè)壓送熔體,因此泵出口可達(dá)到很高的壓力,而流量與排出壓力基本無關(guān)。 一、高溫齒輪泵運(yùn)行管理 1、日常維護(hù) (l)泵的解體和清洗,升、降溫,起停都應(yīng)嚴(yán)格按照規(guī)定操作,以避免不應(yīng)有的損失。 (2)應(yīng)注意保持增壓泵人口壓力的穩(wěn)定,使其具有穩(wěn)定的容積效率,以有利于泵本身運(yùn)行和下游紡絲質(zhì)量的穩(wěn)定。 (3)人口為負(fù)壓的填料軸封泵,應(yīng)保持填料函處壓力高于外界大氣壓。背壓降低時(shí),應(yīng)及時(shí)調(diào)整填料函的壓力,否則會(huì)使泵吸入空氣,造成鑄帶條斷帶,影響切粒,導(dǎo)致切粒機(jī)放流。 (4)要經(jīng)常檢查熱媒夾套的溫度,主體與前、后蓋的熱媒溫度要保持一致。 (5)每一次產(chǎn)量提高時(shí),要將當(dāng)時(shí)的產(chǎn)量、轉(zhuǎn)速、出、入口壓力、電流值記錄下來,并將前后數(shù)據(jù)加以比較,認(rèn)真分析,以便盡早發(fā)現(xiàn)異常,及時(shí)處理。 2、高溫齒輪泵常見故障及對(duì)策如下: (1)故障現(xiàn)象:泵不能排料 故障原因:a、旋轉(zhuǎn)方向相反;b、吸入或排出閥關(guān)閉; c、入口無料或壓力過低; d、粘度過高,泵無法咬料 對(duì)策: a、確認(rèn)旋轉(zhuǎn)方向; b、確認(rèn)閥門是否關(guān)閉; c、檢查閥門和壓力表; d、檢查液體粘度,以低速運(yùn)轉(zhuǎn)時(shí)按轉(zhuǎn)速比例的流量是否出現(xiàn),若有流量,則流入不足、 (2)故障現(xiàn)象:泵流量不足 故障原因:a、吸入或排出閥關(guān)閉; b、入口壓力低; c、出口管線堵塞; d、填料箱泄漏;e、轉(zhuǎn)速過低 對(duì)策:a、確認(rèn)閥門是否關(guān)閉;b、檢查閥門是否打開;c、確認(rèn)排出量是否正常; d、緊固;大量泄露漏影響生產(chǎn)時(shí),應(yīng)停止運(yùn)轉(zhuǎn),拆卸檢查; e、檢查泵軸實(shí)際轉(zhuǎn)速; (3)故障現(xiàn)象:聲音異常 故障原因:a、聯(lián)軸節(jié)偏心大或潤(rùn)滑不良 b、電動(dòng)機(jī)故障; c、減速機(jī)異常; d、軸封處安裝不良; e、軸變形或磨損 對(duì)策:a、找正或充填潤(rùn)滑脂; b、檢查電動(dòng)機(jī); c、檢查軸承和齒輪; d、檢查軸封; e、停車解體檢查 (4)故障現(xiàn)象:電流過大 故障原因:a、出口壓力過高; b、熔體粘度過大;c、軸封裝配不良; d、軸或軸承磨損; e、電動(dòng)機(jī)故障 對(duì)策:a、檢查下游設(shè)備及管線;b、檢驗(yàn)粘度; c、檢查軸封,適當(dāng)調(diào)整; d、停車后檢查,用手盤車是否過重; e、檢查電動(dòng)機(jī) (5)故障現(xiàn)象:泵突然停止 故障原因:a、停電; b、電機(jī)過載保護(hù); c、聯(lián)軸器損壞;d、出口壓力過高,聯(lián)鎖反應(yīng);e、泵內(nèi)咬入異常; f、軸與軸承粘著卡死 對(duì)策:a、檢查電源;b、檢查電動(dòng)機(jī);c、打開安全罩,盤車檢查;d、檢查儀表聯(lián)鎖系統(tǒng);e、停車后,正反轉(zhuǎn)盤車確認(rèn); f、盤車確認(rèn) 說明:以上故障現(xiàn)象和對(duì)策是一一對(duì)應(yīng)關(guān)系 二、提高高溫齒輪泵運(yùn)行壽命的措施 因泵體在高溫下運(yùn)轉(zhuǎn),故冷態(tài)安裝時(shí)配管上應(yīng)設(shè)鉸支座,以防升溫后配管位移。
