●高粘(zhān)度泵(bèng)使用時注(zhù)意事(shì)項matters needing attention when using high viscosity pump

　　進(jìn)、出口(kǒu)管路的管徑必須(xū)和(hé)泵保(bǎo)持一(yī)緻；the diameters of inlet and outlet piping must be consistent with pump;

　　設(shè)計管路時(shí)應盡量減(jiǎn)少(shǎo)彎頭，且彎頭(tóu)角度不(bú)宜(yí)過小，進口(kǒu)管(guǎn)線不宜(yí)過長，以(yǐ)免影響(xiǎng)自吸(xī)。

●高(gāo)粘(zhān)度(dù)泵工(gōng)作原理：

　　高粘度泵是容(róng)積(jī)式内(nèi)齧合齒輪泵，主(zhǔ)動齒輪(lún)（外轉子(zǐ)）帶動(dòng)被(bèi)動齒(chǐ)輪(lún)（内轉子）旋轉時(shí)，不斷(duàn)産(chǎn)生封閉(bì)的空間，在(zài)吸油區齒(chǐ)輪逐(zhú)漸脫(tuō)離齧合而(ér)液體(tǐ)不斷地充滿齒(chǐ)間并被帶到出(chū)油區，齒輪在出(chū)油區進入(rù)齧合時液體被排出(chū)。兩個旋(xuán)轉(zhuǎn)齒輪的共(gòng)同(tóng)作用，形(xíng)成一個穩定的(de)體積排量(liàng)，沒有(yǒu)脈動。由于泵是(shì)完全(quán)對稱的，泵(bèng)可以反(fǎn)轉，液流(liú)方向也随之改(gǎi)變。但應注(zhù)意，泵的轉向(xiàng)可能受到密封或(huò)泵内(nèi)其它結構的限(xiàn)制，用戶(hù)有(yǒu)反轉(zhuǎn)要求時應在訂(dìng)貨時做(zuò)出(chū)說明。　　

●高粘度(dù)泵優點(diǎn)：

　　轉子泵的軸向(xiàng)位置可調，不需(xū)要拆泵。

　　泵(bèng)采用(yòng)模塊化設計，可(kě)根據不(bú)同的使(shǐ)用要求(qiú)更換不同部(bù)件。可(kě)選夾(jiá)層結(jié)構，以方便(biàn)對泵加熱(rè)或冷(lěng)卻，可以選(xuǎn)擇是(shì)否帶安全(quán)閥，可(kě)以選擇不同的(de)密(mì)封(fēng)形式(shì)，詳見(jiàn)密封結構圖。泵(bèng)的各個零件可(kě)以選(xuǎn)用不(bú)同的(de)材質以(yǐ)适應具(jù)體使用要(yào)求。

　　不(bú)同的使用(yòng)條件(jiàn)，泵的(de)結構形式(shì)可能不同(tóng)，具體(tǐ)應用(yòng)請向廠家(jiā)或本(běn)公司(sī)客戶(hù)代表咨詢(xún)。需要(yào)指出的是(shì)泵的(de)轉速(sù)愈高，泵的(de)磨損(sǔn)愈嚴重，液(yè)體(tǐ)中(zhōng)如含有磨(mó)料物質，泵(bèng)的材(cái)料應選(xuǎn)用(yòng)耐磨(mó)材質(zhì)，在此種工(gōng)況下(xià)，泵(bèng)的壓力和轉速都(dōu)應降(jiàng)低，高(gāo)溫條(tiáo)件下，則應增加(jiā)泵的(de)間隙(xì)，并采用耐(nài)熱材料(liào) 。

　　流動穩(wěn)定：流量與齒輪(lún)轉速(sù)成(chéng)正(zhèng)比，與(yǔ)壓力無關(guān)

　　流動平穩(wěn)：沒有(yǒu)脈動(dòng)和壓(yā)力波峰，不會産生(shēng)管(guǎn)道顫(chàn)動。

　　多(duō)功能性：僅(jǐn)僅通過調(diào)整轉(zhuǎn)子軸(zhóu)的位置，同一台泵既(jì)可以(yǐ)出來(lái)稀(xī)釋溶液(yè)又可以出(chū)來(lái)瀝青，糖(táng)漿，樹(shù)脂，聚(jù)合物(wù)等高(gāo)粘度(dù)液體(tǐ)。

　　可(kě)逆性：可(kě)以(yǐ)通過改(gǎi)變齒(chǐ)輪的旋轉方向使液體反(fǎn)向流(liú)動，兩(liǎng)種(zhǒng)方向都(dōu)能充分發(fā)揮泵的性能

　　自吸性(xìng)：由泵産生(shēng)高真空，允許(xǔ)在(zài)最大(dà)自吸高度(dù)實現快速(sù)自(zì)吸，取決于泵送液(yè)體的(de)物理特性（溫(wēn)度，蒸汽(qì)壓(yā)力(lì)，粘度等）。

　　建議性：隻有(yǒu)兩個活(huó)動部件(jiàn)：主動輪和動輪(lún)，隻有一個(gè)軸封(fēng)。

　　堅固(gù)的(de)重載結(jié)構：低轉(zhuǎn)速(sù)。特大球軸(zhóu)承的外部(bù)軸承(chéng)座可(kě)以承(chéng)受軸向和徑向(xiàng)負載。

　　磨損(sǔn)率低(dī)：由于主(zhǔ)動輪和(hé)從動齒(chǐ)輪(lún)不成(chéng)倍(bèi)數關系。這就(jiù)意味着磨損(sǔn)可以被(bèi)均(jun1)勻(yún)的分(fèn)散在每(měi)個(gè)齒輪(lún)上。因(yīn)為一個齒(chǐ)輪(lún)上(shàng)的每一個(gè)齒輪接觸另一(yī)個齒輪上的每(měi)一個(gè)齒(chǐ)輪的次(cì)數一(yī)樣。

磨(mó)損調(diào)節系統(tǒng)：轉子邊(biān)緣的磨損(sǔn)可以(yǐ)通過(guò)調整轉子軸的位置(zhì)來補償。這(zhè)樣，即使在(zài)有相當大的磨(mó)損的情況下，也可以保證(zhèng)泵的穩定性。

　　維(wéi)護簡(jiǎn)單，維護(hù)率低：不(bú)用(yòng)移(yí)動(dòng)泵，管道(dào)或泵驅動(dòng)裝置(zhì)就可以(yǐ)進行檢(jiǎn)查和調(diào)節(jiē)。

　　互動性：标(biāo)準組件的設(shè)計可實(shí)現不(bú)同材(cái)料和(hé)特(tè)性(xìng)零部件(jiàn)之(zhī)間的(de)替換。例如(rú)：有多種軸封系(xì)統可(kě)供選(xuǎn)擇，還可以(yǐ)安裝(zhuāng)帶(dài)夾套的(de)外殼(ké)和軸蓋來(lái)代替(tì)标(biāo)準部件(jiàn)。

　　端口(kǒu)位置(zhì)可改(gǎi)變：泵(bèng)殼可在軸承箱上旋轉以從不同位置處吸排液(yè)體。

　　預熱(rè)：加熱(rè)夾套(tào)或是(shì)與外(wài)殼鑄成一(yī)體，或是安(ān)裝在(zài)端蓋(gài)上，或(huò)是安(ān)裝在(zài)填料(liào)壓蓋(gài)上。

　　旁路安全閥(fá)：旁(páng)路安全(quán)閥安(ān)裝在泵上并且(qiě)容易調節，在有些型(xíng)号的泵上采取雙重(zhòng)安全(quán)閥并帶加熱夾(jiá)套。● 高粘度(dù)泵開(kāi)機準備

　　在開始運轉(zhuǎn)前，往齒輪(lún)泵的殼體内灌(guàn)滿待輸送(sòng)的液(yè)體，便(biàn)于(yú)安全(quán)啟(qǐ)動。若環境溫度(dù)低于(yú)冰(bīng)點，應預先向(xiàng)泵内(nèi)通入(rù)熱蒸汽，進行預(yù)熱處理，然(rán)後才(cái)可啟(qǐ)動齒輪泵(bèng)。高粘度(dù)泵的旋轉方向(xiàng)要與進、出油口相符。齒(chǐ)輪泵若是第一次運行，或長期閑置後再使用，最好(hǎo)在空(kōng)載或小(xiǎo)負荷情況下(xià)先跑合一小時左右。如果在跑(pǎo)合階段預先覺(jiào)察出(chū)異常溫升(shēng)、洩漏、振動和噪(zào)聲時(shí)，應停機檢(jiǎn)查。高(gāo)粘度(dù)齒輪(lún)泵的支(zhī)座或法蘭與其驅動電(diàn)機應采用共同(tóng)的安(ān)裝基礎，基礎、法(fǎ)蘭或(huò)支座(zuò)均需具有足夠的剛度(dù)，以(yǐ)減小(xiǎo)齒輪泵(bèng)運轉時産生的振(zhèn)動(dòng)和(hé)噪聲。電動(dòng)機與(yǔ)齒輪泵須(xū)用彈(dàn)性聯軸器(qì)連接(jiē)，同軸度小于0.1毫(háo)米，傾斜(xié)角(jiǎo)不得(dé)大于(yú)1度。安(ān)裝聯(lián)軸器時不得用(yòng)錘敲打，以免傷(shāng)害(hài)齒輪泵(bèng)的齒(chǐ)輪等(děng)零件(jiàn)。若(ruò)用(yòng)帶輪、鍊(liàn)輪(lún)等驅(qū)動時應設托架(jià)支承，以防(fáng)主動(dòng)齒(chǐ)輪軸承受徑(jìng)向力。緊固(gù)齒輪泵、電(diàn)動機(jī)的地(dì)腳螺釘(dìng)時(shí)，螺釘(dìng)受力(lì)應均勻，連接可靠。用(yòng)手轉(zhuǎn)動聯(lián)軸器時，應(yīng)感覺到齒(chǐ)輪泵(bèng)能夠(gòu)輕(qīng)松地轉(zhuǎn)動，沒有卡緊等(děng)異常現(xiàn)象出現(xiàn)，然後才可(kě)以配管。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)粘度齒輪(lún)泵的吸油管道(dào)内徑(jìng)應足夠大(dà)，并避免(miǎn)狹窄通(tōng)道或急劇(jù)拐彎(wān)、減少彎頭(tóu)，去除(chú)不必(bì)要(yào)的閥門(mén)、附件(jiàn)，盡可(kě)能地降低(dī)泵的安裝(zhuāng)高度，縮短吸(xī)油管道(dào)的長(zhǎng)度，以(yǐ)減少壓力損失(shī)。管接頭等(děng)元件(jiàn)的密封要(yào)良好，以防止空氣(qì)侵(qīn)入，從而控(kòng)制氣穴與氣蝕的發(fā)生。止回閥與安(ān)全閥在(zài)齒輪泵(bèng)的輸出(chū)管路上(shàng)最好安(ān)裝(zhuāng)一個(gè)止回閥。這樣在檢修泵及輸出(chū)管道(dào)時，系統中(zhōng)的液體不會發(fā)生倒流。齒(chǐ)輪泵(bèng)帶負(fù)荷停(tíng)車時(shí)，亦可(kě)防止泵倒(dǎo)轉而(ér)在其輸出(chū)管道(dào)内産生局(jú)部真空(kōng)。應當注(zhù)意，出(chū)口(kǒu)止回閥(fá)不能(néng)裝反或出現卡死(sǐ)現(xiàn)象。高(gāo)粘度(dù)泵的出口(kǒu)管路上還(hái)應當設置安(ān)全閥等保護裝(zhuāng)置，這樣(yàng)一旦泵(bèng)的出口(kǒu)通道發生堵塞，就可(kě)以打(dǎ)開安(ān)全閥卸壓。安全閥可(kě)以與泵體(tǐ)或泵(bèng)蓋(gài)鑄(zhù)成一(yī)體，也可以單獨(dú)裝配(pèi)。對于需要(yào)正反轉(zhuǎn)的高粘(zhān)度齒輪泵，其進(jìn)出口(kǒu)管路(lù)上均(jun1)需設置安(ān)全(quán)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.
