●高粘(zhan)度泵使(shi)用時注(zhu)意事項(xiang)Matters needing attention when using high viscosity pump

　　進、出口(kǒu)管路的(de)管徑必(bi)須和泵(bèng)保持一(yi)緻；The diameters of inlet and outlet piping must be consistent with pump;

　　設計(ji)管路時(shí)應盡量(liàng)減少彎(wan)頭，且彎(wān)頭角度(dù)不宜過(guò)小，進口(kǒu)管線🈲不(bu)宜過長(zhǎng)，以免影(ying)響自吸(xī)。

　　啟動前(qián)每個注(zhu)油杯都(dou)應家潤(rùn)滑油，且(qiě)保證每(měi)天加🍓油(you)一🐪次。

　　泵(beng)在工作(zuo)前應該(gai)點動啟(qi)動電機(jī)，觀察轉(zhuǎn)向是否(fou)和♈規定(ding)🐇轉向一(yī)緻。

　　開機(jī)後觀察(chá)運轉是(shì)否正常(cháng)，如有不(bu)正常噪(zao)音、特殊(shu)🌂振💁動或(huo)溫升過(guò)高等情(qing)況，應停(ting)機檢查(chá)。

　　注意皮(pí)帶松緊(jin)是否恰(qià)當，每半(bàn)年調整(zhěng)一次。　

●高(gao)粘度泵(bèng)工作原(yuán)理：

　　高粘(zhān)度泵是(shì)容積式(shi)内齧合(he)齒輪泵(bèng)，主動齒(chi)輪（外轉(zhuǎn)子）帶動(dong)被動齒(chi)輪（内轉(zhuǎn)子）旋轉(zhuan)時，不斷(duàn)産生封(feng)💘閉的空(kong)間，在吸(xi)油區齒(chǐ)輪逐漸(jiàn)脫離齧(nie)合而液(yè)體不斷(duàn)地充滿(man)齒間并(bing)被帶到(dao)出油區(qū)，齒輪在(zài)🤞出油區(qu)進入齧(niè)合時液(ye)體被排(pái)🚶出。兩個(ge)😘旋轉齒(chǐ)輪的共(gòng)同作用(yòng)，形成一(yi)個穩定(ding)的體積(jī)排量，沒(méi)有脈動(dong)。由于泵(beng)是完全(quan)對稱的(de)，泵可以(yǐ)反轉，液(ye)流方向(xiang)也随之(zhī)😘改變。但(dan)應注意(yì)，泵的轉(zhuan)向可能(neng)受到密(mi)封或泵(bèng)内其它(ta)結構的(de)限制，用(yòng)戶有反(fǎn)轉要求(qiu)時應在(zai)訂貨時(shi)做出說(shuō)明。　　

●高粘(zhan)度泵優(yōu)點：

　　轉子(zi)泵的軸(zhóu)向位置(zhi)可調，不(bu)需要拆(chāi)泵。

　　泵采(cai)用模塊(kuai)化設計(ji)，可根據(ju)不同的(de)使用要(yào)求更換(huan)不同部(bu)件。可選(xuan)夾層結(jie)構，以方(fang)便對泵(bèng)加熱或(huò)冷卻，可(ke)以選擇(zé)是否帶(dài)安全閥(fa)，可以選(xuǎn)擇不同(tong)的密封(fēng)形式，詳(xiáng)見密封(fēng)結構圖(tu)。泵的各(ge)個零件(jian)可以選(xuǎn)用不同(tong)的材質(zhi)以适應(yīng)具體使(shi)用要求(qiu)。

　　不同的(de)使用條(tiao)件，泵的(de)結構形(xíng)式可能(néng)不同，具(jù)體應用(yong)⛷️請❤️向🐪廠(chang)家或本(běn)公司客(kè)戶代表(biao)咨詢。需(xu)要指出(chu)的🥰是泵(bèng)🈚的轉速(sù)愈高，泵(bèng)的磨損(sǔn)愈嚴重(zhong)，液體中(zhōng)如含有(yǒu)💔磨料物(wù)質，泵的(de)材料應(ying)選用耐(nài)磨材質(zhi)，在此種(zhong)工況下(xia)，泵的壓(ya)力和轉(zhuǎn)速都應(yīng)降低，高(gāo)溫條件(jiàn)下，則應(yīng)增加泵(beng)的間隙(xi)，并采用(yong)耐熱材(cái)料 。

　　流動(dòng)穩定：流(liú)量與齒(chǐ)輪轉速(sù)成正比(bi)，與壓力(li)無關

　　流(liú)動平穩(wen)：沒有脈(mo)動和壓(yā)力波峰(feng)，不會産(chan)生管道(dao)顫動。

　　多(duō)功能性(xìng)：僅僅通(tong)過調整(zhěng)轉子軸(zhóu)的位置(zhì)，同一台(tái)泵既可(kě)以出來(lai)稀釋溶(róng)液又可(kě)以出來(lai)瀝青，糖(táng)漿，樹脂(zhi)，聚合🌏物(wù)等高粘(zhān)⭐度液體(ti)。

　　建(jian)議性：隻(zhī)有兩個(ge)活動部(bu)件：主動(dong)輪和動(dòng)輪，隻有(you)一個軸(zhou)封。

　　堅固(gù)的重載(zǎi)結構：低(di)轉速。特(tè)大球軸(zhou)承的外(wài)部軸承(chéng)🤩座可以(yi)承👌受♻️軸(zhou)向和徑(jìng)向負載(zai)。

　　磨損率(lǜ)低：由于(yú)主動輪(lun)和從動(dòng)齒輪不(bu)成倍數(shu)關系。這(zhè)就意味(wèi)着磨損(sǔn)可以被(bèi)均勻的(de)分散在(zài)每個齒(chi)輪上。因(yin)⭐為一個(ge)齒輪上(shàng)的每一(yī)個齒輪(lun)接觸另(ling)一個齒(chi)輪上的(de)每一個(ge)齒輪的(de)次數一(yi)樣。

磨損(sǔn)調節系(xi)統：轉子(zi)邊緣的(de)磨損可(ke)以通過(guò)調整轉(zhuǎn)子軸👄的(de)位🐆置來(lái)補償。這(zhe)樣，即使(shi)在有相(xiang)當大的(de)磨損㊙️的(de)情況下(xia)，也可以(yi)保證泵(beng)的穩定(dìng)性。

　　維護(hu)簡單，維(wei)護率低(dī)：不用移(yi)動泵，管(guǎn)道或泵(bèng)驅動裝(zhuang)置就可(kě)🐕以進行(háng)檢查和(he)調節。

　　互(hù)動性：标(biāo)準組件(jiàn)的設計(jì)可實現(xian)不同材(cái)料和特(te)性零部(bù)件㊙️之間(jian)的替換(huan)。例如：有(yǒu)多種軸(zhou)封系統(tong)可供選(xuǎn)擇，還可(ke)以🚶‍♀️安裝(zhuang)帶夾套(tao)的外殼(ke)和軸蓋(gai)來代替(ti)标準部(bu)件。

　　端口(kou)位置可(ke)改變：泵(beng)殼可在(zài)軸承箱(xiang)上旋轉(zhuǎn)以從不(bú)同位置(zhì)處吸排(pai)液體。

　　預(yu)熱：加熱(re)夾套或(huo)是與外(wài)殼鑄成(cheng)一體，或(huo)是安裝(zhuāng)在端蓋(gai)上，或是(shì)安裝在(zai)填料壓(yā)蓋上。

　　旁(páng)路安全(quan)閥：旁路(lu)安全閥(fá)安裝在(zai)泵上并(bìng)且容易(yi)調節，在(zài)有些型(xíng)号的泵(bèng)上采取(qu)雙重安(ān)全閥并(bìng)帶加熱(rè)夾套。● 高(gao)粘度泵(bèng)開機準(zhun)備
