我公(gōng)司生産的nyp高(gāo)粘度(dù)泵用(yòng)作高粘(zhān)度(dù)打膠(jiāo)泵是非常合(hé)适(shì)的泵從(cóng)結構上(shàng)看:自吸(xī)性能強(qiáng)，适用于輸送不(bú)含固體顆粒和(hé)纖維的(de)粘稠液(yè)體，甚至是(shì)半固體狀态的(de)液體，最高輸(shū)送粘度(dù)達到3*105厘泊。具有(yǒu)體積(jī)小、重量輕(qīng)、脈動小、噪(zào)音低(dī)、運轉平穩(wěn)、壽命(mìng)長等(děng)優點(diǎn)。nyp high viscosity of the inner ring type pump is a kind of positive displacement rotor pump.this type of pump self-priming performance is strong, is suitable for conveying viscous liquid containing no solid particles and fibers, even half solid state of liquid, conveying viscosity up to 3 * 105 centipoise.with small volume, light weight, small ripple, low noise, smooth operation, long service life, etc.●高粘度泵工(gōng)作(zuò)原理(lǐ)：

　　高粘(zhān)度泵(bèng)是容積式内齧合齒(chǐ)輪泵，主(zhǔ)動齒輪(lún)（外轉(zhuǎn)子）帶(dài)動被(bèi)動齒輪（内(nèi)轉子(zǐ)）旋轉時，不斷産(chǎn)生封閉(bì)的空間(jiān)，在吸(xī)油(yóu)區齒輪(lún)逐漸(jiàn)脫(tuō)離齧合(hé)而液(yè)體不斷地(dì)充滿齒(chǐ)間(jiān)并被帶到出油(yóu)區，齒(chǐ)輪在出油(yóu)區進(jìn)入齧(niè)合時液體(tǐ)被排出(chū)。兩個旋轉齒輪的共同作用，形成一個穩定的(de)體積排量，沒(méi)有脈(mò)動。由于(yú)泵是(shì)完(wán)全對(duì)稱的，泵可(kě)以反轉，液流方向也(yě)随之改變。但應(yīng)注意(yì)，泵的轉向(xiàng)可能受(shòu)到密封(fēng)或泵内(nèi)其它結(jié)構的限制，用戶有反轉要求時(shí)應在訂貨(huò)時做出說(shuō)明。　　

●高粘度(dù)泵優點：

　　轉子泵(bèng)的軸(zhóu)向(xiàng)位置可調，不需要(yào)拆泵(bèng)。

　　泵采用模塊化設計，可(kě)根據不(bú)同的(de)使用(yòng)要求更換不(bú)同部件(jiàn)。可選(xuǎn)夾(jiá)層結構(gòu)，以方便對(duì)泵加熱或(huò)冷卻，可以(yǐ)選擇是否(fǒu)帶(dài)安(ān)全閥，可(kě)以選擇(zé)不同的密(mì)封形式，詳(xiáng)見密(mì)封結(jié)構(gòu)圖。泵的(de)各個(gè)零件可以選用(yòng)不同的材(cái)質以(yǐ)适應(yīng)具(jù)體使用要求。

　　不同的使用條(tiáo)件，泵的結(jié)構形式可(kě)能(néng)不(bú)同，具體(tǐ)應用請(qǐng)向廠家(jiā)或本公(gōng)司客(kè)戶代表咨(zī)詢。需要指(zhǐ)出的(de)是泵的轉速愈(yù)高，泵的(de)磨(mó)損愈嚴重(zhòng)，液體中如(rú)含有磨料物質，泵的材料應選(xuǎn)用耐(nài)磨材(cái)質，在(zài)此種工況下，泵(bèng)的壓力和轉速都應(yīng)降低，高溫(wēn)條件下，則(zé)應增(zēng)加泵的(de)間(jiān)隙，并采用耐(nài)熱材料 。

　　流動(dòng)穩定：流量(liàng)與齒輪轉速成(chéng)正比(bǐ)，與壓(yā)力無(wú)關

　　流動平(píng)穩：沒(méi)有脈動和壓力(lì)波峰，不會(huì)産生管道顫動(dòng)。

　　多功(gōng)能性：僅(jǐn)僅通過調整轉子(zǐ)軸的(de)位置，同一台泵既可(kě)以出來稀(xī)釋溶(róng)液又可以出來(lái)瀝(lì)青，糖漿(jiāng)，樹脂，聚合物等(děng)高粘度液體。

　　可(kě)逆性：可以通過(guò)改變(biàn)齒輪的旋(xuán)轉方向使液體(tǐ)反向(xiàng)流(liú)動(dòng)，兩種方向都能(néng)充分發揮(huī)泵的性能(néng)

　　自吸性：由(yóu)泵産生高真(zhēn)空，允許(xǔ)在最大自(zì)吸高(gāo)度實現(xiàn)快(kuài)速自(zì)吸，取決(jué)于泵送(sòng)液體的物理特(tè)性（溫度，蒸(zhēng)汽壓(yā)力，粘(zhān)度等）。

　　建議(yì)性：隻(zhī)有兩(liǎng)個活動部(bù)件：主動輪(lún)和動輪，隻有一(yī)個軸(zhóu)封。

　　堅固的(de)重載結構：低轉速。特大球(qiú)軸承的外部軸(zhóu)承座(zuò)可以承受軸向(xiàng)和徑向負(fù)載。

　　磨(mó)損率(lǜ)低：由于主(zhǔ)動輪和從(cóng)動齒(chǐ)輪不(bú)成(chéng)倍數關系。這就意(yì)味着(zhe)磨損(sǔn)可以被均(jun1)勻的分散在(zài)每(měi)個齒(chǐ)輪上。因為(wéi)一個齒(chǐ)輪上的(de)每一個齒(chǐ)輪接(jiē)觸另一個(gè)齒輪(lún)上的每一個(gè)齒(chǐ)輪的次數一樣。

磨損(sǔn)調節系統(tǒng)：轉子(zǐ)邊(biān)緣的磨(mó)損可(kě)以通(tōng)過調(diào)整轉子軸的(de)位(wèi)置來(lái)補償(cháng)。這樣(yàng)，即使在(zài)有相當(dāng)大的磨損的情(qíng)況(kuàng)下，也(yě)可以保(bǎo)證泵的穩定性。

　　維護簡單(dān)，維護率低(dī)：不用移動泵，管(guǎn)道或泵驅(qū)動裝(zhuāng)置就可以(yǐ)進行檢查和調(diào)節。

　　互(hù)動性：标準(zhǔn)組件的設(shè)計可實現(xiàn)不同(tóng)材料(liào)和特性零(líng)部件之間的替換。例(lì)如：有多種(zhǒng)軸封(fēng)系統可供選擇(zé)，還可以安裝帶(dài)夾套的(de)外(wài)殼和(hé)軸蓋來代替标(biāo)準部件(jiàn)。

　　端(duān)口位(wèi)置可改(gǎi)變：泵殼(ké)可在(zài)軸承箱上(shàng)旋轉以從(cóng)不同位置(zhì)處吸排(pái)液(yè)體。

　　預熱(rè)：加(jiā)熱夾(jiá)套或是與外殼(ké)鑄成一體，或是(shì)安裝在(zài)端蓋上(shàng)，或是安裝在(zài)填料壓(yā)蓋上(shàng)。

　　旁路(lù)安全閥：旁(páng)路安全閥(fá)安裝在泵(bèng)上并且容易調(diào)節，在(zài)有些(xiē)型号的泵上(shàng)采(cǎi)取雙重安(ān)全閥并帶(dài)加熱夾套。●高粘度(dù)泵的(de)工作壓(yā)力的選(xuǎn)定

　　1, select the work pressure

　　高粘度泵額定(dìng)的壓(yā)力是指泵連續工作(zuò)時的最高許用壓力，而其(qí)工作壓力(lì)則決(jué)定于(yú)外部(bù)負載，安裝(zhuāng)和調試的(de)壽命(mìng)與其(qí)工作壓力(lì)直接(jiē)相關(guān)。對于不頻繁工(gōng)作的齒輪泵，其(qí)工作壓力可取(qǔ)為泵(bèng)的額定壓(yā)力，考慮到産品(pǐn)質量不同，最好(hǎo)将額定壓(yā)力降低20%～30%使(shǐ)用。對于經(jīng)常工作于較高壓力下的齒輪(lún)泵，其工作壓(yā)力(lì)應比泵的額定壓力低(dī)1～2個(gè)壓力(lì)級。石(shí)油化工設(shè)備(bèi)常(cháng)常(cháng)是(shì)24小時(shí)連續運(yùn)轉，這時(shí)泵的(de)工作壓力(lì)應該取得比額(é)定壓力低(dī)得多(duō)，且工作轉速也(yě)應該低于額定轉速。如果高粘度齒輪(lún)泵的工(gōng)作壓力調整過(guò)高，則(zé)會使齒輪(lún)泵在(zài)超(chāo)負荷下運行。high viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.for not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.for often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.petrochemical equipment are often 24 hours of continuous operation, and at this time of the pump working pressure should be obtained was much lower than the rated pressure, and the work speed should be lower than the rated speed.if the high viscosity gear pump high pressure adjustment, will make the pump running under overload.

●nyp高粘(zhān)度泵(bèng)的安(ān)裝與試運轉

　　installation and commissioning

　　高(gāo)粘度泵的(de)支(zhī)座或法蘭與(yǔ)其驅動電機(jī)應(yīng)采用共同的安(ān)裝基礎，基(jī)礎、法(fǎ)蘭或支座均需(xū)具(jù)有足夠(gòu)的剛度，以減(jiǎn)小齒(chǐ)輪(lún)泵運轉時産生的振(zhèn)動和噪聲。電動機與齒輪泵須用彈性聯(lián)軸器(qì)連接，同軸度小于0.1毫米，傾(qīng)斜角不得大于1度。安裝聯(lián)軸器(qì)時(shí)不(bú)得用(yòng)錘敲(qiāo)打，以(yǐ)免傷害(hài)齒(chǐ)輪泵的齒(chǐ)輪等零件(jiàn)。若用帶輪(lún)、鍊輪(lún)等驅動時(shí)應設托架支承(chéng)，以防主動齒輪軸承受徑(jìng)向力(lì)。緊固齒輪泵、電(diàn)動機的地腳螺(luó)釘時，螺釘(dìng)受力(lì)應均勻，連接可(kě)靠。用手轉(zhuǎn)動聯(lián)軸器時(shí)，應(yīng)感覺(jiào)到齒(chǐ)輪(lún)泵(bèng)能夠(gòu)輕松(sōng)地轉動，沒(méi)有卡緊等(děng)異常(cháng)現象出現，然後(hòu)才可以(yǐ)配管。高粘度齒輪泵的(de)吸油管道内徑(jìng)應足夠大(dà)，并避(bì)免狹窄通道或(huò)急劇拐(guǎi)彎、彎頭(tóu)，去除不(bú)必(bì)要的(de)閥門、附件，盡可(kě)能地降低泵的安裝(zhuāng)高度(dù)，縮短(duǎn)吸油管(guǎn)道的長度，以(yǐ)減(jiǎn)少壓力損(sǔn)失。管接(jiē)頭等(děng)元件的密封要(yào)良好，以防止空氣侵入，從而控(kòng)制氣穴與氣蝕(shí)的發(fā)生。在開始(shǐ)運轉(zhuǎn)前，往齒(chǐ)輪泵的殼體(tǐ)内灌(guàn)滿待輸(shū)送(sòng)的液(yè)體，便于安全動(dòng)。若環(huán)境(jìng)溫(wēn)度低(dī)于冰(bīng)點(diǎn)，應預先(xiān)向泵(bèng)内(nèi)通入熱(rè)蒸汽，進(jìn)行預熱(rè)處理(lǐ)，然後才可(kě)啟動(dòng)齒輪泵。齒(chǐ)輪泵的旋轉方(fāng)向要(yào)與進(jìn)、出油口相符。齒(chǐ)輪泵若是第一次運(yùn)行，或長期閑置(zhì)後再(zài)使用，最好(hǎo)在空(kōng)載或小負荷情況下先跑合一(yī)小時左右(yòu)。如果(guǒ)在(zài)跑合階(jiē)段預(yù)先覺出異(yì)常溫升(shēng)、洩漏、振(zhèn)動和(hé)噪聲(shēng)時，應(yīng)機檢查。高粘度泵的出口管路(lù)上還(hái)應當設置(zhì)安全閥(fá)等保護裝置(zhì)，這(zhè)樣一旦(dàn)泵的出口通道(dào)發生(shēng)堵塞(sāi)，就可(kě)以打開安全閥卸壓。對于需要(yào)正反(fǎn)轉(zhuǎn)的(de)高粘(zhān)度齒輪(lún)泵(bèng)，其進(jìn)出口管路(lù)上均(jun1)需設(shè)置安(ān)全閥(fá)。high viscosity pump bearing or flange and its drive motor should use common installation basis, 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 gear and other parts of the gear pump.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.high viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp bend, bend, 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.before starting operation, to gear pump casing filled with liquid, easy to safety.if the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.direction of rotation of the gear pump, 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 the abnormal temperature rise, leakage, vibration and noise, should machine inspection.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.for high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
