●高粘度(dù)泵優點：

　　轉子(zǐ)泵的軸(zhóu)向位置可(kě)調，不(bú)需要(yào)拆(chāi)泵。

　　泵采(cǎi)用模塊(kuài)化(huà)設計(jì)，可根(gēn)據(jù)不同的(de)使用要(yào)求(qiú)更換(huàn)不同(tóng)部(bù)件(jiàn)。可(kě)選夾層(céng)結構(gòu)，以方(fāng)便對泵加熱或(huò)冷卻(què)，可以(yǐ)選擇(zé)是否(fǒu)帶安全閥(fá)，可以(yǐ)選擇不同(tóng)的密封(fēng)形(xíng)式，詳(xiáng)見密封結構圖。泵的(de)各個(gè)零件可以選用(yòng)不同(tóng)的材(cái)質(zhì)以(yǐ)适應(yīng)具體使用(yòng)要求。

　　不同的使用條(tiáo)件，泵的結構形(xíng)式可能不(bú)同，具(jù)體應(yīng)用請(qǐng)向廠家或(huò)本公司客戶代表(biǎo)咨(zī)詢。需(xū)要指出(chū)的是泵的轉速愈高，泵(bèng)的磨損愈嚴重(zhòng)，液體(tǐ)中如含有(yǒu)磨料物質，泵的(de)材料應(yīng)選用耐(nài)磨(mó)材質(zhì)，在此種(zhǒng)工況(kuàng)下，泵(bèng)的(de)壓(yā)力和轉速(sù)都應(yīng)降低，高溫(wēn)條件下，則應增(zēng)加泵(bèng)的間隙(xì)，并采用耐熱材料 。

　　流動(dòng)穩定：流量(liàng)與齒輪轉(zhuǎn)速成(chéng)正比(bǐ)，與壓力無關

　　流(liú)動平穩(wěn)：沒有脈(mò)動和壓力(lì)波峰(fēng)，不會(huì)産(chǎn)生管道(dào)顫動(dòng)。

　　多功(gōng)能性(xìng)：僅僅通過調整(zhěng)轉子軸的(de)位置(zhì)，同一台泵既可(kě)以出來(lái)稀(xī)釋溶(róng)液又(yòu)可以出來(lái)瀝青，糖漿(jiāng)，樹脂(zhī)，聚(jù)合(hé)物等高粘(zhān)度液體。

　　可(kě)逆性：可以(yǐ)通過(guò)改變(biàn)齒輪的旋轉方(fāng)向使(shǐ)液體(tǐ)反向流動，兩種(zhǒng)方向(xiàng)都能(néng)充分發揮(huī)泵的性能

　　自吸(xī)性：由泵産(chǎn)生高(gāo)真空，允(yǔn)許(xǔ)在最(zuì)大(dà)自吸(xī)高度實(shí)現快速自吸，取(qǔ)決于泵送液體的物理特性（溫(wēn)度，蒸(zhēng)汽壓力，粘(zhān)度等）。

　　建(jiàn)議(yì)性：隻有兩(liǎng)個活動(dòng)部件：主動輪和動輪，隻(zhī)有(yǒu)一(yī)個軸(zhóu)封。

　　堅固(gù)的(de)重載結構(gòu)：低轉速。特(tè)大球軸承的外部軸(zhóu)承(chéng)座(zuò)可以(yǐ)承受軸(zhóu)向(xiàng)和徑向負載。

　　磨損率低：由于主(zhǔ)動輪(lún)和從(cóng)動(dòng)齒輪不(bú)成倍(bèi)數關(guān)系。這就意(yì)味着磨損(sǔn)可以(yǐ)被均(jun1)勻的(de)分散(sàn)在每(měi)個齒(chǐ)輪上。因為一個(gè)齒輪上(shàng)的每一(yī)個齒輪接觸另一個(gè)齒輪上的每一個齒輪的次數(shù)一樣。

磨(mó)損(sǔn)調節系統(tǒng)：轉子(zǐ)邊緣的磨(mó)損可(kě)以通(tōng)過調(diào)整轉(zhuǎn)子軸的位置來(lái)補償(cháng)。這樣，即使在有相當大的磨損的情況下(xià)，也可(kě)以(yǐ)保證泵(bèng)的穩定性。

　　維護(hù)簡單，維(wéi)護率低(dī)：不用(yòng)移(yí)動(dòng)泵，管(guǎn)道或泵(bèng)驅動裝置就(jiù)可以進行檢查和(hé)調節。

　　互(hù)動性(xìng)：标準組(zǔ)件(jiàn)的設計可(kě)實現(xiàn)不同材料和特(tè)性零部(bù)件之間的替(tì)換。例如：有(yǒu)多種軸封系(xì)統可供(gòng)選(xuǎn)擇，還可以安裝帶(dài)夾套的外(wài)殼和(hé)軸蓋(gài)來代替标準部(bù)件。

　　端(duān)口(kǒu)位置可(kě)改變：泵殼(ké)可在(zài)軸承箱上(shàng)旋轉(zhuǎn)以從不同位置(zhì)處(chù)吸排(pái)液體。

　　預(yù)熱：加熱夾套或(huò)是與外殼鑄成(chéng)一體(tǐ)，或(huò)是安裝(zhuāng)在端蓋上，或是(shì)安裝在填料壓(yā)蓋上。

　　旁路安全(quán)閥：旁路安全閥(fá)安裝在泵上并且容易調節，在(zài)有些型号的泵(bèng)上采取雙重安(ān)全閥并(bìng)帶加熱(rè)夾套。

●nyp高粘度泵的進出口

　　泵進(jìn)出(chū)口的型式

　　常(cháng)規泵進出(chū)口尺(chǐ)寸相同(tóng)，進出口(kǒu)呈垂(chuí)直布(bù)置，從驅動(dòng)機(jī)向泵頭(tóu)方向(xiàng)看(kàn)為(wéi)右進(jìn)上出。也(yě)可根(gēn)據(jù)客戶需要(yào)，加工(gōng)成水平進(jìn)出口(kǒu)型或(huò)左進上出(chū)型。連接方(fāng)式有(yǒu)法蘭型和(hé)螺紋型.

　　泵(bèng)進出口負(fù)荷

　　泵(bèng)在(zài)安(ān)裝時，應限(xiàn)制泵的進(jìn)出(chū)口所(suǒ)承(chéng)受的(de)管路負荷(hé)。螺紋(wén)聯接的(de)管(guǎn)接頭(tóu)不得(dé)承(chéng)受負荷(hé)，否則(zé)會使泵的(de)聯接(jiē)管産生松(sōng)動或旋緊力(lì)矩(jǔ)（管螺紋(wén)聯接處不允許有(yǒu)旋緊或松動的扭矩(jǔ)，以(yǐ)免）影(yǐng)響(xiǎng)管路的聯接效(xiào)果。

●nyp高粘度泵的起動

　　泵在起動過程(chéng)中應特别注意以下幾(jǐ)個問題(tí)：

　　起動(dòng)前(qián)要檢查下列(liè)内容(róng)：

　　檢查泵、齒輪箱(xiāng)和電(diàn)機的對(duì)中程度(dù)；

　　檢查過濾器中有沒有焊皮和(hé)金屬渣；

　　檢查各(gè)連接(jiē)部位連接是否緊固(gù)；

　　檢查管(guǎn)路壓(yā)在泵上(shàng)的力和力矩是(shì)否超過給定的(de)數值，如(rú)果溫度(dù)較高(gāo)，還應(yīng)檢查(chá)管路是否有膨(péng)脹節(jiē)；

　　檢查電氣(qì)連接的正(zhèng)确性及電(diàn)機的額定(dìng)值，并檢查電機(jī)轉(zhuǎn)動(dòng)方向是否(fǒu)正确；

　　檢查泵的轉動方向是否(fǒu)正确；

　　如有安全(quán)閥，安全(quán)閥安裝(zhuāng)必須正确(què)，

　　檢查(chá)泵軸是否轉動(dòng)靈活(huó)；

　　泵的(de)内部不能(néng)是(shì)幹的，特(tè)别是(shì)需(xū)要自吸的時候，應向泵(bèng)内灌(guàn)注一(yī)些油(yóu)或輸送的液體(tǐ)；

　　泵組(zǔ)裝(zhuāng)時在零件的表面有防(fáng)護液(yè)，如果這種(zhǒng)液體不能和泵(bèng)送液體相(xiàng)容，則必須(xū)清洗；

　　最好(hǎo)在管路(lù)上(shàng)安裝壓力表和真空(kōng)表，方便觀察(chá)泵(bèng)的工作狀态；

　　檢(jiǎn)查機械密封箱(xiāng)是否注(zhù)滿液體(tǐ)；

　　檢查管路的閥(fá)門是(shì)否打開；

　　如(rú)果用内燃(rán)機驅(qū)動，請在(zài)起(qǐ)動發(fā)動機前(qián)保持離合器脫(tuō)開；

　　泵起(qǐ)動後，檢查(chá)液體(tǐ)是否進(jìn)入(rù)到泵(bèng)中，泵是否工作(zuò)正常(cháng)，如果(guǒ)長時(shí)間(jiān)無(wú)液(yè)體(tǐ)進入(rù)泵中(zhōng)，應(yīng)停機檢查泵(bèng)及管(guǎn)路。

●高(gāo)粘度(dù)齒輪泵并(bìng)不能産生壓力(lì)，它隻(zhī)是(shì)輸出流(liú)量。壓力低(dī)或無(wú)壓力，說明高粘(zhān)度齒 輪泵沒有(yǒu)吸入液體或洩漏嚴重。high viscosity gear pump does not generate pressure, it is only the output flow.pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious.

　　電動機(jī)輸出(chū)功率(lǜ)偏小、齒 輪(lún)泵排(pái)量選(xuǎn)得過(guò)大或壓力調得(dé)過高時，也(yě)會造(zào)成壓力不(bú)足 當然，壓(yā)力表(biǎo)損壞或壓(yā)力表(biǎo)節流孔(kǒng)堵(dǔ)塞時(shí)也顯(xiǎn)示不出壓力，此時(shí)可換裝(zhuāng)一個(gè)新的壓力(lì)表檢查。small motor output power, gear wheel pump capacity to choose too large or pressure too high, can cause stress pressure gauge damage or pressure gauge orifice jams, of course, also could not show pressure, can change a new pressure gauge to check at this time.

　　如果确認泵無流量輸出，可(kě)能(néng)是(shì)由于(yú)泵安裝有誤、泵(bèng)的轉向(xiàng)不(bú)對(duì)，或吸人側(進(jìn)液口(kǒu)及吸液(yè)管(guǎn)道)堵(dǔ)塞、出口(kǒu)止回閥(fá)裝(zhuāng)反(fǎn)或卡(kǎ)死了(le)，也有(yǒu)可能是驅(qū)動軸斷裂了。if confirmed that no flow pump output, could be turned to the pumps due to pump installation is wrong, wrong, or suction side (liquid into the mouth and suck liquid pipeline jam, export check valve installed backwards, or card is dead, it is possible that the drive shaft fracture.

　　高粘度(dù)泵在轉速過低(dī)時會引起出液量不足，這(zhè)種現(xiàn)象往(wǎng)往是由于(yú)泵的驅動裝置打滑(huá)或功率不足(zú)所(suǒ)緻。此(cǐ)時(shí)應(yīng)檢查齒 輪(lún)泵的實際(jì)轉速(sù)、泵與電動(dòng)機的(de)聯接(jiē)及功率匹配情況等(děng)。high viscosity pump in low speed can cause insufficient quantity of produced liquid, this phenomenon is often due to the slippage of the pump drive or insufficient power.check the gear wheel pump at this time of the actual speed, pump and motor connection and power matching, etc.

● 高粘(zhān)度泵(bèng)開(kāi)機(jī)準備(bèi)

　　在開(kāi)始運轉前，往齒輪泵的殼(ké)體内(nèi)灌(guàn)滿待輸送的液體，便于(yú)安全啟動(dòng)。若環(huán)境溫度低于冰(bīng)點，應預(yù)先(xiān)向泵(bèng)内通(tōng)入熱蒸汽(qì)，進行預熱(rè)處理，然後(hòu)才可(kě)啟動(dòng)齒輪泵。高(gāo)粘(zhān)度泵的旋轉(zhuǎn)方向(xiàng)要與進(jìn)、出油口(kǒu)相符。齒(chǐ)輪(lún)泵若是(shì)第一(yī)次運行(háng)，或長(zhǎng)期(qī)閑置後(hòu)再使用(yòng)，最(zuì)好在(zài)空載或(huò)小(xiǎo)負荷(hé)情況(kuàng)下(xià)先跑合(hé)一小(xiǎo)時左右。如(rú)果在跑合階段(duàn)預先覺察(chá)出異(yì)常溫升(shēng)、洩漏、振動和(hé)噪聲時，應(yīng)停機檢(jiǎn)查。高粘(zhān)度齒輪(lún)泵(bèng)的支(zhī)座或法蘭與其驅動電機(jī)應采用共(gòng)同的安裝(zhuāng)基礎，基(jī)礎、法蘭(lán)或支座均(jun1)需(xū)具(jù)有足夠的剛度，以減小(xiǎo)齒輪泵(bèng)運轉(zhuǎn)時産生的(de)振(zhèn)動和噪聲。電(diàn)動機(jī)與齒輪泵(bèng)須用彈(dàn)性聯軸器連接，同軸度(dù)小于0.1毫米，傾斜(xié)角不得大于1度(dù)。安裝聯軸(zhóu)器時(shí)不得(dé)用(yòng)錘敲打(dǎ)，以免(miǎn)傷(shāng)害齒輪(lún)泵的(de)齒輪等零件(jiàn)。若用帶(dài)輪、鍊(liàn)輪等驅動時應(yīng)設托架支(zhī)承，以(yǐ)防主(zhǔ)動(dòng)齒輪軸(zhóu)承受(shòu)徑向力。緊(jǐn)固齒(chǐ)輪泵、電動(dòng)機的地腳(jiǎo)螺(luó)釘時，螺(luó)釘受力應(yīng)均勻，連接可靠(kào)。用手轉動聯軸(zhóu)器時(shí)，應(yīng)感(gǎn)覺到(dào)齒輪泵能夠(gòu)輕(qīng)松地轉動，沒有(yǒu)卡緊(jǐn)等(děng)異常現(xiàn)象出現，然後才(cái)可(kě)以配管(guǎn)。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.

     高粘(zhān)度齒(chǐ)輪泵(bèng)的吸油管(guǎn)道内徑應(yīng)足夠(gòu)大(dà)，并(bìng)避免(miǎn)狹窄(zhǎi)通(tōng)道或急(jí)劇拐彎、減(jiǎn)少彎(wān)頭，去除不必要(yào)的閥門、附件，盡(jìn)可能地降低泵(bèng)的安裝(zhuāng)高度，縮(suō)短吸油管道的(de)長度，以減少壓(yā)力損(sǔn)失。管接頭(tóu)等元件的密封要良(liáng)好，以防止(zhǐ)空氣侵入，從而(ér)控制氣穴與氣蝕的發(fā)生(shēng)。止回(huí)閥與安全閥在齒輪(lún)泵的輸出管路(lù)上最好安(ān)裝一個止(zhǐ)回閥。這樣(yàng)在檢修泵(bèng)及輸出管道時(shí)，系統中(zhōng)的液體(tǐ)不會發生倒流。齒輪(lún)泵帶負荷(hé)停車時，亦(yì)可防止泵倒(dǎo)轉而在(zài)其輸(shū)出管(guǎn)道内産(chǎn)生(shēng)局(jú)部真空(kōng)。應當注意，出口(kǒu)止回(huí)閥不(bú)能裝(zhuāng)反或出(chū)現(xiàn)卡死(sǐ)現象(xiàng)。高(gāo)粘度泵(bèng)的(de)出口管路上還應當設置安全閥等(děng)保(bǎo)護裝置，這樣(yàng)一旦泵(bèng)的出口通道發(fā)生堵(dǔ)塞(sāi)，就可以(yǐ)打開安全(quán)閥卸(xiè)壓。安(ān)全閥(fá)可以(yǐ)與泵(bèng)體或泵蓋(gài)鑄成(chéng)一體，也可(kě)以單獨(dú)裝配。對(duì)于需要正反(fǎn)轉(zhuǎn)的高粘度(dù)齒輪(lún)泵，其進出口管(guǎn)路上(shàng)均需設置安(ān)全閥。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.

   高粘度(dù)泵是輸(shū)送高粘(zhān)度液(yè)體的(de)齒輪(lún)泵，應(yīng)做到在較(jiào)低的功耗(hào)、較少(shǎo)的(de)洩漏、較大的壓力下輸出最多的流(liú)量。在确定所要輸送的(de)介質(zhì)時(shí)，應(yīng)該嚴(yán)格(gé)遵循産品說(shuō)明書上的規定，盡量(liàng)使用廠家(jiā)推薦的(de)流(liú)體介質，并(bìng)注意考慮(lǜ)系統的工作溫(wēn)度範(fàn)圍。當希望(wàng)在某一較寬的(de)溫度範圍(wéi)内使(shǐ)用時(shí)，輸送(sòng)介質(zhì)的粘(zhān)度指(zhǐ)數應(yīng)該高些。輸送介(jiè)質不僅(jǐn)是(shì)能量(liàng)傳遞(dì)的(de)中(zhōng)介，而(ér)且也是潤滑、密封及傳熱(rè)介質(zhì)。液體粘(zhān)度過高(gāo)會增加内(nèi)摩擦(cā)阻力，降低輸出(chū)功率，浪費能量(liàng)，并産生過高的(de)系統溫度.高粘(zhān)度齒(chǐ)輪(lún)泵(bèng)的出口管(guǎn)路上應當設置(zhì)安全閥等(děng)保(bǎo)護裝置(zhì)，這樣(yàng)一旦(dàn)泵的出口(kǒu)通道(dào)發生(shēng)堵塞(sāi)，就可(kě)以打開安(ān)全閥卸壓。對于(yú)需要正反轉的(de)高粘度齒輪泵，其進出口(kǒu)管路(lù)上均需(xū)設(shè)置安(ān)全閥(fá)。high viscosity pump is conveying liquid with high viscosity gear pump, should be in lower power consumption, less leakage, under the pressure of large output the most traffic.when determining to conveying medium, we should strictly follow the provisions of the product manuals on use manufacturers recommend fluid as far as possible, and pay attention to consider the system operating temperature range.when you want to use in a wide temperature range, medium viscosity index should be higher.medium is not only the energy transfer intermediary, but also lubrication, sealing and heat transfer medium.liquid viscosity is too high will increase internal friction resistance, lower output power, waste of energy, and generate high temperature system. high viscosity gear pump outlet pipe shall set up relief valve or other protective device on the road, so once the clogging pump export channels, can open the relief valve pressure relief.for high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
