●高粘度(dù)泵優點：

　　轉子泵(bèng)的軸(zhóu)向位置可(kě)調，不(bú)需要拆泵。

　　泵采(cǎi)用模(mó)塊化(huà)設計，可根(gēn)據不同的(de)使用要求(qiú)更換(huàn)不同部件(jiàn)。可選(xuǎn)夾層結構，以方(fāng)便對(duì)泵(bèng)加熱或(huò)冷卻(què)，可以選擇(zé)是否帶安全閥(fá)，可以選擇(zé)不同(tóng)的密封形式，詳見密封結(jié)構圖。泵的(de)各個零件(jiàn)可以選用不同(tóng)的材(cái)質以适應具體(tǐ)使用(yòng)要求。

　　不同的使(shǐ)用條(tiáo)件，泵的結構形(xíng)式可能不同，具(jù)體應用請(qǐng)向廠(chǎng)家或本(běn)公司客(kè)戶代表咨(zī)詢。需要指(zhǐ)出的是泵的轉速(sù)愈(yù)高，泵(bèng)的磨損愈嚴重，液體中(zhōng)如含有(yǒu)磨料(liào)物(wù)質(zhì)，泵的(de)材料應(yīng)選(xuǎn)用耐磨(mó)材質(zhì)，在此種(zhǒng)工況下，泵的壓(yā)力和轉速(sù)都應(yīng)降低(dī)，高溫條件下，則(zé)應增加泵的間隙(xì)，并(bìng)采用耐熱材(cái)料 。

　　流動穩定：流量(liàng)與齒(chǐ)輪轉速(sù)成(chéng)正比(bǐ)，與壓力(lì)無關

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

　　多功能性：僅僅(jǐn)通過調整(zhěng)轉子軸(zhóu)的(de)位置(zhì)，同一(yī)台(tái)泵(bèng)既可以出來稀(xī)釋溶(róng)液又(yòu)可以出來(lái)瀝青(qīng)，糖漿，樹脂(zhī)，聚合物等高粘(zhān)度液體(tǐ)。

　　可逆(nì)性：可以通過改變(biàn)齒輪的(de)旋轉方向使(shǐ)液體反向(xiàng)流動，兩種方向都能充分(fèn)發揮泵的性能

　　自吸(xī)性：由泵(bèng)産(chǎn)生高(gāo)真空，允許(xǔ)在最(zuì)大自(zì)吸高度實(shí)現快(kuài)速自(zì)吸，取(qǔ)決于泵送(sòng)液體(tǐ)的物理特性（溫(wēn)度，蒸汽壓力，粘度(dù)等）。

　　建議性：隻(zhī)有兩(liǎng)個活動部(bù)件：主(zhǔ)動輪(lún)和動(dòng)輪，隻有(yǒu)一個軸封。

　　堅(jiān)固的(de)重載(zǎi)結(jié)構：低轉速。特(tè)大球(qiú)軸承的外(wài)部軸(zhóu)承座可以承受軸向(xiàng)和徑(jìng)向負載。

　　磨損率低(dī)：由于主動輪(lún)和從動齒輪不(bú)成倍數關(guān)系。這(zhè)就意味(wèi)着磨損可以(yǐ)被均勻的分散在每個齒(chǐ)輪上。因為(wéi)一個齒輪(lún)上的每一(yī)個齒輪接觸另(lìng)一個(gè)齒輪上的每一(yī)個齒(chǐ)輪的(de)次數(shù)一樣。

磨損(sǔn)調節系統(tǒng)：轉子邊緣(yuán)的(de)磨(mó)損可(kě)以通過調(diào)整轉子軸(zhóu)的位置來(lái)補償。這樣(yàng)，即使(shǐ)在有相當大的(de)磨損的情況下(xià)，也可以保證泵(bèng)的穩(wěn)定性。

　　維護(hù)簡單，維護(hù)率低(dī)：不用移動(dòng)泵，管道或泵(bèng)驅動裝(zhuāng)置就可(kě)以進行(háng)檢查和(hé)調(diào)節。

　　互(hù)動性：标準組件(jiàn)的設計可實現(xiàn)不同材料和特(tè)性零部件之間(jiān)的替換。例如：有(yǒu)多種軸封系統(tǒng)可供選擇，還可(kě)以安(ān)裝帶夾套(tào)的外(wài)殼和(hé)軸蓋來(lái)代替(tì)标準部(bù)件。

　　端口位(wèi)置(zhì)可(kě)改變：泵殼可在(zài)軸承箱上旋轉(zhuǎn)以從不同位置(zhì)處吸排液(yè)體。

　　預(yù)熱：加(jiā)熱夾(jiá)套(tào)或(huò)是與(yǔ)外殼鑄成一體(tǐ)，或是安裝在端蓋上，或是(shì)安裝(zhuāng)在(zài)填料壓(yā)蓋上。

　　旁路(lù)安(ān)全閥：旁路安全閥(fá)安裝(zhuāng)在泵上并且容(róng)易調節，在(zài)有(yǒu)些(xiē)型(xíng)号(hào)的泵上采取雙重安(ān)全閥并帶(dài)加熱(rè)夾套。

●nyp高粘(zhān)度泵(bèng)的進出口(kǒu)

　　泵進(jìn)出口的型式

　　常(cháng)規泵進出口(kǒu)尺(chǐ)寸相同，進出口呈垂直(zhí)布置，從(cóng)驅動機(jī)向泵頭(tóu)方向看為右進(jìn)上出。也可根據客戶需要(yào)，加工(gōng)成水平(píng)進出口(kǒu)型或左進上出(chū)型。連(lián)接(jiē)方(fāng)式有(yǒu)法蘭型和螺紋型.

　　泵(bèng)進出口負(fù)荷

　　泵在安(ān)裝時，應限制(zhì)泵(bèng)的進(jìn)出口所(suǒ)承受的管路負荷(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(huì)使(shǐ)泵的聯(lián)接(jiē)管産生松(sōng)動或旋緊(jǐn)力矩(jǔ)（管螺紋聯接處(chù)不允許(xǔ)有旋緊(jǐn)或松(sōng)動的扭矩(jǔ)，以免）影響(xiǎng)管路(lù)的聯(lián)接效果。

●nyp高(gāo)粘度泵的(de)起動(dòng)

　　泵在起(qǐ)動過程(chéng)中應特别(bié)注意以下(xià)幾個問題(tí)：

　　起動(dòng)前要檢查下列内容(róng)：

　　檢查(chá)泵、齒輪箱(xiāng)和電機的(de)對中程度(dù)；

　　檢查過濾(lǜ)器中(zhōng)有沒(méi)有(yǒu)焊皮和(hé)金屬渣；

　　檢(jiǎn)查各連接部位連接(jiē)是否緊(jǐn)固；

　　檢查(chá)管路(lù)壓在(zài)泵上(shàng)的力和力(lì)矩是(shì)否超(chāo)過給定的數值，如果(guǒ)溫度(dù)較高，還(hái)應檢查(chá)管(guǎn)路是否有膨(péng)脹節；

　　檢查電氣(qì)連接的正(zhèng)确性及電機的額定(dìng)值，并檢(jiǎn)查(chá)電機(jī)轉動方向是否(fǒu)正确；

　　檢(jiǎn)查(chá)泵(bèng)的(de)轉動(dòng)方向(xiàng)是否(fǒu)正确；

　　如有(yǒu)安全閥，安(ān)全閥安裝(zhuāng)必須正确(què)，

　　檢查(chá)泵軸是否轉動(dòng)靈活；

　　泵的(de)内部(bù)不能是幹的，特(tè)别是需要(yào)自吸(xī)的時(shí)候(hòu)，應向泵(bèng)内灌(guàn)注(zhù)一(yī)些(xiē)油或輸送的液體(tǐ)；

　　泵組(zǔ)裝時在零件的(de)表面(miàn)有防護液，如(rú)果這種(zhǒng)液體(tǐ)不能(néng)和泵送液體相(xiàng)容，則(zé)必須(xū)清洗(xǐ)；

　　最好在管路上(shàng)安裝(zhuāng)壓力表和真空(kōng)表，方便觀(guān)察泵的工(gōng)作(zuò)狀(zhuàng)态；

　　檢(jiǎn)查機械(xiè)密(mì)封箱(xiāng)是否(fǒu)注滿(mǎn)液體(tǐ)；

　　檢查管路的閥(fá)門是(shì)否打(dǎ)開；

　　如(rú)果用内燃機驅動，請(qǐng)在起動發(fā)動機(jī)前保持離(lí)合器(qì)脫(tuō)開；

　　泵起(qǐ)動後，檢查液體是否(fǒu)進入(rù)到泵中，泵(bèng)是(shì)否工作正常，如果長時(shí)間無液體進入泵中(zhōng)，應停機檢(jiǎn)查泵及管(guǎn)路。

●高粘度齒(chǐ)輪(lún)泵并(bìng)不能産生壓力，它(tā)隻(zhī)是輸(shū)出流(liú)量。壓(yā)力低或(huò)無(wú)壓力，說明(míng)高粘(zhān)度齒(chǐ) 輪(lún)泵沒有(yǒu)吸入(rù)液體或洩(xiè)漏嚴(yán)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(diàn)動機(jī)輸出功率(lǜ)偏(piān)小(xiǎo)、齒 輪泵排(pái)量選得過(guò)大或(huò)壓力調得過高(gāo)時，也(yě)會造成壓力不(bú)足 當然，壓(yā)力表(biǎo)損壞或壓(yā)力表(biǎo)節流孔堵(dǔ)塞時也顯(xiǎn)示不出壓(yā)力，此時(shí)可(kě)換裝(zhuāng)一個新的(de)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(bèng)無流量輸(shū)出，可能(néng)是由于(yú)泵安裝有誤、泵(bèng)的轉(zhuǎn)向不(bú)對，或吸人(rén)側(cè)(進(jìn)液口(kǒu)及吸液管道)堵塞、出(chū)口(kǒu)止(zhǐ)回閥(fá)裝反(fǎn)或卡死了(le)，也有可能(néng)是驅(qū)動軸斷裂(liè)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)泵在轉速過低時(shí)會引起(qǐ)出液量不足，這(zhè)種現象往往(wǎng)是(shì)由于泵的(de)驅動裝置打(dǎ)滑或功(gōng)率不足所緻。此(cǐ)時(shí)應檢查齒 輪泵的實際轉速、泵與電動機的聯接(jiē)及(jí)功(gōng)率匹(pǐ)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.

● 高粘度(dù)泵開(kāi)機準備(bèi)

　　在開始運(yùn)轉(zhuǎn)前(qián)，往齒輪泵(bèng)的殼(ké)體内(nèi)灌(guàn)滿待輸(shū)送的(de)液體，便于(yú)安全啟動。若環境溫(wēn)度低(dī)于冰(bīng)點，應預先(xiān)向泵(bèng)内通入熱(rè)蒸汽(qì)，進行預熱處理，然後才可啟動(dòng)齒輪泵。高粘度泵的(de)旋轉方向(xiàng)要與進、出油口(kǒu)相符(fú)。齒(chǐ)輪(lún)泵若是第一次運行(háng)，或長期閑置後(hòu)再使用，最好在空載(zǎi)或小負荷(hé)情況下先跑合(hé)一小時左(zuǒ)右。如(rú)果在跑合(hé)階段預先覺察(chá)出異常溫升、洩漏、振動和(hé)噪聲時，應(yīng)停(tíng)機檢查。高粘(zhān)度齒(chǐ)輪(lún)泵的支(zhī)座或法蘭(lán)與其驅動(dòng)電(diàn)機應采(cǎi)用共(gòng)同的(de)安裝(zhuāng)基(jī)礎，基礎、法蘭(lán)或支座均需具(jù)有足(zú)夠的(de)剛度(dù)，以減小(xiǎo)齒輪泵(bèng)運轉(zhuǎn)時(shí)産生的振(zhèn)動和噪聲。電(diàn)動機與齒(chǐ)輪泵(bèng)須用彈性(xìng)聯軸器連接(jiē)，同(tóng)軸度(dù)小于0.1毫米，傾斜角不(bú)得大于1度(dù)。安裝(zhuāng)聯軸(zhóu)器時(shí)不得用錘(chuí)敲打(dǎ)，以免傷害齒輪(lún)泵的齒輪等零(líng)件。若用(yòng)帶輪、鍊(liàn)輪等(děng)驅動時應(yīng)設托(tuō)架支(zhī)承，以(yǐ)防主動齒(chǐ)輪軸(zhóu)承受徑向力。緊(jǐn)固(gù)齒輪泵(bèng)、電動(dòng)機的地腳螺釘時，螺(luó)釘受力應(yīng)均勻，連(lián)接可靠。用手(shǒu)轉動聯軸(zhóu)器時(shí)，應感覺到(dào)齒輪泵能夠輕(qīng)松地轉動(dòng)，沒有(yǒu)卡緊(jǐn)等異常現(xiàn)象出(chū)現，然後才(cái)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.

     高粘(zhān)度齒輪泵的吸(xī)油管道内(nèi)徑應(yīng)足夠大(dà)，并(bìng)避免(miǎn)狹窄通道或急劇(jù)拐彎、減少彎(wān)頭，去(qù)除(chú)不必要(yào)的閥門、附(fù)件，盡可能(néng)地降(jiàng)低泵的安(ān)裝高(gāo)度，縮短吸(xī)油管道的(de)長度，以減(jiǎn)少壓力損失。管(guǎn)接頭(tóu)等元件的密封(fēng)要良(liáng)好，以防止(zhǐ)空氣侵入，從而(ér)控制氣穴與氣蝕的發生。止回(huí)閥與(yǔ)安全閥在(zài)齒輪(lún)泵的輸出(chū)管路(lù)上最好安(ān)裝一個止回閥(fá)。這樣在檢(jiǎn)修泵(bèng)及輸出管(guǎn)道時(shí)，系統(tǒng)中(zhōng)的液體不會發生(shēng)倒流(liú)。齒輪(lún)泵帶負(fù)荷(hé)停車時，亦(yì)可防(fáng)止泵(bèng)倒轉(zhuǎn)而在(zài)其輸出管(guǎn)道内(nèi)産生(shēng)局(jú)部真空(kōng)。應當注意，出口(kǒu)止回閥不能裝(zhuāng)反或(huò)出現卡死(sǐ)現象(xiàng)。高(gāo)粘度泵(bèng)的出口管路上(shàng)還應當設置安(ān)全閥等保(bǎo)護裝(zhuāng)置，這(zhè)樣一旦泵(bèng)的出口通(tōng)道發(fā)生(shēng)堵塞(sāi)，就可以(yǐ)打開安全閥卸(xiè)壓。安全閥可以與泵體或(huò)泵蓋(gài)鑄成(chéng)一體，也可(kě)以單獨裝配。對(duì)于需(xū)要正(zhèng)反(fǎn)轉(zhuǎn)的高粘(zhān)度(dù)齒輪泵，其(qí)進(jìn)出口管(guǎn)路上(shàng)均(jun1)需設置(zhì)安全(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.

   高粘度(dù)泵是輸送(sòng)高粘度液體的(de)齒輪(lún)泵，應做(zuò)到在較低的(de)功耗(hào)、較少(shǎo)的洩(xiè)漏、較(jiào)大的(de)壓力下輸出(chū)最(zuì)多的流(liú)量(liàng)。在确(què)定所(suǒ)要輸送的(de)介質時(shí)，應該嚴(yán)格遵(zūn)循産品說(shuō)明書上的規定，盡量(liàng)使用(yòng)廠家推薦的流(liú)體介(jiè)質，并(bìng)注(zhù)意考慮(lǜ)系統的(de)工作溫(wēn)度範(fàn)圍。當希望(wàng)在某一較(jiào)寬的(de)溫度範圍内使(shǐ)用時，輸送介質的粘度指數應(yīng)該高些。輸送介(jiè)質不僅是(shì)能量(liàng)傳遞的(de)中介，而且也(yě)是潤滑、密(mì)封及傳熱介質(zhì)。液體粘度過高會增加内(nèi)摩擦(cā)阻力(lì)，降低輸出(chū)功率(lǜ)，浪費能量(liàng)，并産生(shēng)過(guò)高的(de)系統溫(wēn)度(dù).高粘(zhān)度齒(chǐ)輪泵的出(chū)口管路上(shàng)應當設置(zhì)安全(quán)閥等(děng)保護裝置，這樣(yàng)一旦(dàn)泵的出口(kǒu)通道(dào)發生堵塞，就可(kě)以(yǐ)打開安(ān)全閥卸壓。對于(yú)需(xū)要正反轉的(de)高粘度齒(chǐ)輪(lún)泵(bèng)，其進出口(kǒu)管路上均需設(shè)置安全閥。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.
