●高粘(zhān)度泵使用(yòng)時注(zhù)意事項matters needing attention when using high viscosity pump

　　進(jìn)、出口管路的(de)管(guǎn)徑必須和(hé)泵保(bǎo)持一緻；the diameters of inlet and outlet piping must be consistent with pump;

　　設計管(guǎn)路時應盡量減少彎(wān)頭，且彎頭(tóu)角度不宜過小，進口管線(xiàn)不宜過長，以免影響(xiǎng)自吸(xī)。

　　啟動前每(měi)個注油(yóu)杯(bēi)都應(yīng)家潤滑油，且保(bǎo)證每天加油一(yī)次。

　　泵(bèng)在工(gōng)作前(qián)應該點動(dòng)啟動電機，觀(guān)察轉向(xiàng)是否和規(guī)定轉(zhuǎn)向一(yī)緻。

　　開(kāi)機後(hòu)觀察(chá)運(yùn)轉是否正常(cháng)，如有不正(zhèng)常噪(zào)音、特殊振動或溫升過高(gāo)等情況，應(yīng)停機(jī)檢查。

　　注意皮帶(dài)松緊是否恰當(dāng)，每半年(nián)調(diào)整一(yī)次。　

●高粘度泵工(gōng)作原理：

　　高粘度(dù)泵是容積式内(nèi)齧合齒輪泵，主動齒輪（外轉子(zǐ)）帶動被動齒輪(lún)（内轉子）旋(xuán)轉時(shí)，不斷(duàn)産生(shēng)封閉(bì)的空(kōng)間，在(zài)吸油(yóu)區齒輪逐漸脫(tuō)離齧合而液體不斷地充滿齒間并被(bèi)帶到出油區，齒(chǐ)輪在出(chū)油區進入(rù)齧合(hé)時液體(tǐ)被(bèi)排出(chū)。兩個旋(xuán)轉齒輪(lún)的共同(tóng)作(zuò)用，形(xíng)成一(yī)個穩定的體積排(pái)量，沒有(yǒu)脈動。由于(yú)泵是(shì)完全(quán)對稱的，泵(bèng)可以反轉(zhuǎn)，液流(liú)方向(xiàng)也随之改(gǎi)變。但應注意，泵的轉向(xiàng)可能受(shòu)到密(mì)封或(huò)泵内其它結構的限(xiàn)制，用戶有(yǒu)反轉(zhuǎn)要求時應在訂(dìng)貨時做出說明(míng)。　　

●高粘度泵(bèng)優點(diǎn)：

　　轉子(zǐ)泵(bèng)的軸向位置(zhì)可調(diào)，不需(xū)要拆泵。

　　泵采用(yòng)模塊(kuài)化設計，可(kě)根據不同(tóng)的使(shǐ)用要求更換不(bú)同部件。可選夾(jiá)層(céng)結構，以方便(biàn)對泵加熱或冷卻，可(kě)以選擇是(shì)否帶(dài)安(ān)全閥，可以選擇不(bú)同的密封形(xíng)式，詳見(jiàn)密封結(jié)構圖。泵(bèng)的各個零(líng)件可(kě)以選(xuǎn)用不同的(de)材質以适應具(jù)體使用要求。

　　不(bú)同的使用(yòng)條件，泵的結構形式(shì)可能不(bú)同(tóng)，具體(tǐ)應用請向(xiàng)廠家(jiā)或本公司客戶(hù)代表(biǎo)咨詢。需要(yào)指出(chū)的(de)是(shì)泵的轉速愈高(gāo)，泵的(de)磨損愈嚴重，液(yè)體(tǐ)中(zhōng)如(rú)含有磨(mó)料物質，泵的材料應選用耐磨(mó)材質，在此種工(gōng)況下，泵(bèng)的(de)壓力(lì)和轉速(sù)都應降(jiàng)低，高溫條件下(xià)，則應(yīng)增加泵的(de)間隙，并采用耐(nài)熱材料 。

　　流動穩定：流量與齒輪(lún)轉速成正(zhèng)比，與(yǔ)壓力(lì)無(wú)關

　　流動平穩：沒有脈動和壓力波峰，不(bú)會産(chǎn)生管(guǎn)道顫動。

　　多功(gōng)能(néng)性：僅(jǐn)僅通過調(diào)整轉子軸的(de)位置，同(tóng)一台泵(bèng)既(jì)可以(yǐ)出(chū)來稀(xī)釋溶液(yè)又可以出(chū)來瀝青，糖漿，樹(shù)脂，聚(jù)合物等高粘度(dù)液體(tǐ)。

　　可逆(nì)性：可(kě)以通過改(gǎi)變齒(chǐ)輪的旋轉方向(xiàng)使液(yè)體反向流(liú)動，兩種(zhǒng)方向都(dōu)能充(chōng)分發(fā)揮泵(bèng)的性(xìng)能

　　自吸性(xìng)：由泵(bèng)産生(shēng)高真(zhēn)空，允許在(zài)最大(dà)自吸高度實現(xiàn)快速(sù)自吸(xī)，取決(jué)于泵(bèng)送液(yè)體的(de)物理特(tè)性（溫度(dù)，蒸汽壓力(lì)，粘度(dù)等）。

　　建(jiàn)議性：隻有(yǒu)兩個活動(dòng)部件：主動(dòng)輪和動輪(lún)，隻有(yǒu)一個(gè)軸封(fēng)。

　　堅固的重(zhòng)載結(jié)構：低轉速。特大球軸承的外部(bù)軸(zhóu)承座可(kě)以承(chéng)受軸(zhóu)向和徑向(xiàng)負載。

　　磨損(sǔn)率低(dī)：由于(yú)主(zhǔ)動輪和(hé)從動齒輪不成(chéng)倍(bèi)數(shù)關系(xì)。這就(jiù)意味着(zhe)磨(mó)損可以被均勻的分(fèn)散在每個齒輪(lún)上。因為(wéi)一(yī)個齒(chǐ)輪上的每一個(gè)齒輪(lún)接觸另一(yī)個齒輪(lún)上的每一個齒輪的次(cì)數一樣。

磨損調(diào)節系統：轉子邊(biān)緣的磨損可以(yǐ)通過(guò)調整轉子(zǐ)軸的(de)位置(zhì)來補(bǔ)償。這(zhè)樣，即使在(zài)有相(xiàng)當(dāng)大(dà)的磨損的情況下，也(yě)可以保證(zhèng)泵的(de)穩定(dìng)性。

　　維護簡單，維護率低：不(bú)用移動泵，管道(dào)或泵驅(qū)動裝置(zhì)就可以進(jìn)行檢(jiǎn)查和調節(jiē)。

　　互動(dòng)性：标(biāo)準組(zǔ)件的(de)設計可實現不(bú)同材料(liào)和特(tè)性零部件之(zhī)間的(de)替換。例(lì)如(rú)：有多(duō)種軸封系統可(kě)供(gòng)選擇，還可以(yǐ)安裝帶(dài)夾套的(de)外殼(ké)和(hé)軸蓋來(lái)代替标(biāo)準部件。

　　端口(kǒu)位置(zhì)可改(gǎi)變：泵殼可在軸(zhóu)承箱(xiāng)上旋(xuán)轉(zhuǎn)以(yǐ)從不同位置處(chù)吸排(pái)液體。

　　預熱(rè)：加熱(rè)夾(jiá)套(tào)或是(shì)與(yǔ)外殼鑄(zhù)成一(yī)體，或是(shì)安(ān)裝在(zài)端蓋(gài)上，或是安(ān)裝在(zài)填(tián)料(liào)壓蓋(gài)上。

　　旁(páng)路安全閥(fá)：旁路安全(quán)閥安(ān)裝在(zài)泵上并且容易(yì)調節(jiē)，在有(yǒu)些型(xíng)号(hào)的泵上(shàng)采取雙重(zhòng)安全閥并帶加熱夾(jiá)套。● 高粘度(dù)泵開機準備

　　在開始(shǐ)運轉(zhuǎn)前，往(wǎng)齒輪泵的(de)殼體(tǐ)内灌(guàn)滿待輸送(sòng)的液(yè)體，便于安全啟(qǐ)動。若環境(jìng)溫度(dù)低于冰點，應預(yù)先向泵内通入(rù)熱(rè)蒸汽，進行預(yù)熱處理，然(rán)後(hòu)才可啟動齒(chǐ)輪泵(bèng)。高粘度(dù)泵的旋轉方(fāng)向要與進(jìn)、出(chū)油口相符。齒(chǐ)輪泵(bèng)若是(shì)第(dì)一次運行(háng)，或長期閑置後再使用(yòng)，最好在空(kōng)載或(huò)小負(fù)荷情況下(xià)先跑合一小(xiǎo)時左右(yòu)。如果(guǒ)在跑(pǎo)合階(jiē)段預(yù)先覺察出異常溫升(shēng)、洩漏、振動和噪(zào)聲時(shí)，應停機檢查。高(gāo)粘度(dù)齒輪(lún)泵的支座或法(fǎ)蘭與其驅動電(diàn)機(jī)應(yīng)采用共同(tóng)的安裝基礎，基礎、法蘭或支座(zuò)均需具(jù)有足夠的剛度，以減小(xiǎo)齒(chǐ)輪(lún)泵運轉時(shí)産生(shēng)的振(zhèn)動和(hé)噪聲。電動機與齒輪泵(bèng)須(xū)用彈性聯(lián)軸器(qì)連接(jiē)，同軸度(dù)小于0.1毫(háo)米，傾(qīng)斜(xié)角(jiǎo)不得大于1度。安(ān)裝聯(lián)軸器時不(bú)得用(yòng)錘敲(qiāo)打，以(yǐ)免傷(shāng)害齒輪泵的齒(chǐ)輪等零件。若用(yòng)帶輪、鍊輪(lún)等驅動時(shí)應(yīng)設(shè)托架(jià)支承(chéng)，以防主動(dòng)齒(chǐ)輪軸(zhóu)承受徑(jìng)向力。緊固齒輪(lún)泵、電動(dòng)機的地腳螺釘時，螺釘受力應(yīng)均(jun1)勻，連(lián)接可靠(kào)。用手轉(zhuǎn)動聯(lián)軸器時，應(yīng)感覺到齒輪泵(bèng)能夠(gòu)輕松(sōng)地轉(zhuǎn)動，沒有卡緊等異常現象出現(xiàn)，然後才可以配(pèi)管。high viscosity pump before starting work, to gear pump casing filled with liquid, facilitate safe launch.if the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.the direction of rotation of the pump with high viscosity, oil outlet in accord.gear pump is the first run, or long-term idle before using, had better under the condition of no load or small load to run one hour or so.if in the running-in stage in advance detect abnormal temperature rise, leakage, vibration and noise, should stop check.high viscosity gear pump bearing or flange should adopt a common drive motor installationfoundation, foundation, flange or support all needs to have enough rigidity, to reduce the vibration of gear pump is running and noise.motor and gear pump with elastic shaft coupling, coaxial degree is less than 0.1 mm, angle shall not be greater than 1 degree.when installing coupling hammer shall not be used, in order to avoid damage of the gear pump gearand other parts.if use the belt wheel, wheel, etc, shall set bracket support, in case of driving gear bearing by the radial force.ground screw fastening gear pump, motor, screw force should be uniform, reliable connection.turn the coupling with the hand, should feel can easily turn the gear pump, no abnormal phenomenon such as clamping, then can be piping.

     高(gāo)粘度(dù)齒輪(lún)泵的(de)吸油(yóu)管道(dào)内徑應(yīng)足(zú)夠大，并(bìng)避免狹窄通道或(huò)急劇拐彎(wān)、減少彎頭，去除不必(bì)要的閥門(mén)、附件(jiàn)，盡可(kě)能地降(jiàng)低泵的安裝(zhuāng)高度，縮短吸油(yóu)管道(dào)的(de)長度，以(yǐ)減少壓(yā)力(lì)損失(shī)。管接頭等元件(jiàn)的密(mì)封(fēng)要良好(hǎo)，以防(fáng)止空氣侵(qīn)入，從而控(kòng)制氣(qì)穴與氣(qì)蝕的發(fā)生。止回(huí)閥(fá)與安全閥在齒輪泵(bèng)的輸(shū)出管路上(shàng)最好(hǎo)安裝一個(gè)止回閥(fá)。這樣在(zài)檢修(xiū)泵及輸出(chū)管道時，系統中(zhōng)的液體不會發(fā)生倒流。齒(chǐ)輪泵帶負(fù)荷(hé)停(tíng)車時(shí)，亦可防(fáng)止泵倒轉而(ér)在其輸出(chū)管道内産生局(jú)部真(zhēn)空。應當注(zhù)意，出(chū)口止回閥不能(néng)裝反或出(chū)現卡死現象。高(gāo)粘度(dù)泵的出口(kǒu)管路(lù)上還(hái)應當(dāng)設置(zhì)安全閥等保護裝(zhuāng)置，這樣(yàng)一旦(dàn)泵的出口(kǒu)通道(dào)發生(shēng)堵塞(sāi)，就可(kě)以打(dǎ)開安全閥卸(xiè)壓(yā)。安全(quán)閥可以與泵體或泵蓋鑄(zhù)成一體，也(yě)可以單(dān)獨裝配。對于(yú)需要正反轉(zhuǎn)的高粘(zhān)度齒輪泵，其進出口管路(lù)上均(jun1)需設置(zhì)安全閥(fá)。high viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp turn, reducing elbow, remove unnecessary valves, fittings, as much as possible to reduce the installation height of pump, shorten the length of the oil suction pipe, in order to reduce the pressure loss.components, such as pipe joint sealed well, in order to prevent the air intrusion, thus control air-pocket and the occurrence of cavitation.check valve and relief valve on the output of the gear pump tube had better install a check valve.in the overhaul pump and output pipe, the system of fluid backflow will not occur.gear pump to stop loading machine, can be in the output pipe to prevent pump reverse, and create a partial vacuum.it should be noted that the outlet check valve cannot be installed backwards or stuck.high viscosity of the pump outlet pipe also shall set up relief valve or other protective device on the road, so that once the clogging pump export channels, can open the relief valve pressure relief.the relief valve can be cast and pump body and pump cover, also can separate assembly.for high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
