我(wǒ)公司(sī)生産(chǎn)的nyp高(gāo)粘(zhān)度泵用(yòng)作高粘度(dù)打膠(jiāo)泵是非(fēi)常合(hé)适(shì)的泵(bèng)從結(jié)構上看:自(zì)吸(xī)性能強(qiáng),适用(yòng)于輸送不(bú)含固體顆粒和(hé)纖維的粘稠(chóu)液體,甚至是半固(gù)體狀态的(de)液體(tǐ),最高(gāo)輸送粘度(dù)達到3*105厘泊(bó)。具有(yǒu)體積(jī)小、重量輕、脈動小、噪(zào)音低(dī)、運轉平穩、壽命長等(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.●高粘度泵工作原理(lǐ): 高粘度(dù)泵是容(róng)積式内齧(niè)合齒(chǐ)輪泵,主(zhǔ)動齒輪(外轉(zhuǎn)子)帶(dài)動被(bèi)動(dòng)齒輪(内轉子(zǐ))旋轉(zhuǎn)時,不斷産(chǎn)生封閉的(de)空間,在吸油(yóu)區齒輪逐漸(jiàn)脫離齧合而液(yè)體不(bú)斷地(dì)充滿齒間并被(bèi)帶到(dào)出油區,齒(chǐ)輪在(zài)出油(yóu)區進(jìn)入齧(niè)合時液體被排出。兩個旋轉齒輪(lún)的共同(tóng)作用,形(xíng)成一個(gè)穩定的(de)體積排量,沒有脈動。由(yóu)于泵是完全對(duì)稱的(de),泵(bèng)可以(yǐ)反(fǎn)轉,液(yè)流方向也随之(zhī)改(gǎi)變。但應注意(yì),泵的(de)轉向(xiàng)可能(néng)受到密封(fēng)或泵内其它結(jié)構的限制(zhì),用戶(hù)有反轉(zhuǎn)要求時應在訂貨時做出說(shuō)明。 ●高粘度(dù)泵優點(diǎn): 轉子泵(bèng)的軸(zhóu)向位置可(kě)調,不需要(yào)拆泵。 泵采(cǎi)用模塊化(huà)設計(jì),可根據不(bú)同的使(shǐ)用要求(qiú)更換不同(tóng)部件。可選夾層結構(gòu),以方便(biàn)對泵加(jiā)熱或冷卻,可以(yǐ)選擇是否(fǒu)帶安(ān)全閥(fá),可以(yǐ)選擇(zé)不同的密(mì)封形(xíng)式,詳見密封結構(gòu)圖。泵的(de)各個(gè)零件(jiàn)可以選用(yòng)不同的材(cái)質以(yǐ)适應(yīng)具體使用(yòng)要求。 不(bú)同(tóng)的使用條(tiáo)件,泵的結(jié)構形(xíng)式可(kě)能(néng)不同,具(jù)體應用請(qǐng)向廠家或本公司客(kè)戶(hù)代表咨(zī)詢(xún)。需要指(zhǐ)出的(de)是泵的(de)轉(zhuǎn)速愈(yù)高,泵的磨(mó)損愈嚴重(zhòng),液(yè)體(tǐ)中如(rú)含有磨料物質(zhì),泵(bèng)的(de)材料應選(xuǎn)用耐磨材(cái)質,在(zài)此種工況下,泵(bèng)的壓力和轉速(sù)都應(yīng)降(jiàng)低(dī),高溫條件(jiàn)下,則應增(zēng)加泵的間隙,并(bìng)采用耐(nài)熱材料(liào) 。 流動(dòng)穩定:流量與齒(chǐ)輪(lún)轉(zhuǎn)速成正比,與壓力無(wú)關 流動平(píng)穩:沒(méi)有脈(mò)動和(hé)壓力(lì)波峰,不會産生(shēng)管道顫動。 多功(gōng)能(néng)性(xìng):僅僅(jǐn)通過調整(zhěng)轉子軸的(de)位置,同一(yī)台泵既可以出來稀釋溶液又(yòu)可以(yǐ)出來瀝(lì)青,糖漿(jiāng),樹脂,聚合(hé)物等高粘(zhān)度液體。 可逆性:可(kě)以通過(guò)改變(biàn)齒輪的旋(xuán)轉方(fāng)向(xiàng)使液體(tǐ)反向(xiàng)流動,兩種(zhǒng)方向都能(néng)充分(fèn)發揮(huī)泵(bèng)的性能 自吸性:由泵産生高真空,允許(xǔ)在最(zuì)大自吸高度實(shí)現快(kuài)速自吸,取決于(yú)泵送液體(tǐ)的物理特性(溫度,蒸汽壓(yā)力,粘度(dù)等)。 建議(yì)性:隻(zhī)有兩個活(huó)動部件(jiàn):主(zhǔ)動輪(lún)和動輪(lún),隻(zhī)有一個(gè)軸(zhóu)封(fēng)。 堅固的(de)重載結構(gòu):低轉速。特大球軸承(chéng)的外部軸承座可以承受軸向(xiàng)和徑(jìng)向(xiàng)負(fù)載。 磨(mó)損率(lǜ)低:由(yóu)于主(zhǔ)動輪和(hé)從(cóng)動齒(chǐ)輪不成倍數關系。這(zhè)就意味着磨損可以被均(jun1)勻的分(fèn)散(sàn)在每個齒輪上。因為(wéi)一個(gè)齒(chǐ)輪上的(de)每一(yī)個齒輪接(jiē)觸另一個(gè)齒輪(lún)上的(de)每(měi)一個(gè)齒輪的次(cì)數(shù)一樣(yàng)。 磨損(sǔn)調(diào)節系統(tǒng):轉子(zǐ)邊緣的磨損可以(yǐ)通(tōng)過調(diào)整轉子軸的位(wèi)置來(lái)補(bǔ)償(cháng)。這樣,即使在有相當大的(de)磨損的情(qíng)況下,也可(kě)以保證泵(bèng)的穩定性(xìng)。 維護簡單(dān),維護率低:不用移動(dòng)泵,管道(dào)或泵驅動裝(zhuāng)置(zhì)就可以(yǐ)進行檢查和調(diào)節。 互(hù)動性:标準(zhǔn)組件的設計可實現(xiàn)不同材料(liào)和特性零部件(jiàn)之間的替換。例如:有(yǒu)多種(zhǒng)軸封(fēng)系統可(kě)供(gòng)選擇,還可以安裝帶(dài)夾(jiá)套(tào)的外殼和(hé)軸蓋來代替标準部件。 端口位置可改變:泵殼(ké)可在(zài)軸(zhóu)承箱上(shàng)旋轉以從(cóng)不同位置處吸排液(yè)體。 預熱:加熱夾(jiá)套或是(shì)與(yǔ)外殼(ké)鑄成(chéng)一體,或是(shì)安裝(zhuāng)在端(duān)蓋上(shàng),或是(shì)安裝(zhuāng)在填料壓(yā)蓋上。 旁路(lù)安全閥:旁路安(ān)全閥安(ān)裝在泵(bèng)上并(bìng)且容(róng)易調(diào)節,在(zài)有些型号(hào)的泵上采(cǎi)取雙(shuāng)重安全(quán)閥(fá)并帶(dài)加熱(rè)夾套。 1, select the work pressure 高粘度泵(bèng)額(é)定(dìng)的壓(yā)力是指(zhǐ)泵(bèng)連續(xù)工作(zuò)時的最高(gāo)許用壓(yā)力(lì),而其(qí)工作(zuò)壓力則決(jué)定于外部(bù)負載(zǎi),安裝和調試的(de)壽命與其工作(zuò)壓力直(zhí)接相關(guān)。對于不頻繁工作的齒輪(lún)泵,其(qí)工作壓力(lì)可取為泵的額定壓(yā)力,考慮到(dào)産品質量不(bú)同,最好(hǎo)将額(é)定壓(yā)力降(jiàng)低20%~30%使(shǐ)用(yòng)。對于經(jīng)常工(gōng)作于較高(gāo)壓力(lì)下的齒輪(lún)泵,其工(gōng)作壓力應比(bǐ)泵的額定(dìng)壓力低1~2個壓力級。石(shí)油化(huà)工設(shè)備常常是24小時(shí)連續運轉,這時(shí)泵的工作(zuò)壓力(lì)應該取得(dé)比額(é)定壓力低得多(duō),且(qiě)工作轉速也(yě)應該低(dī)于(yú)額定轉速。如果(guǒ)高粘(zhān)度齒輪(lún)泵的工(gōng)作壓力(lì)調整過(guò)高,則會使(shǐ)齒輪(lún)泵在超負(fù)荷下(xià)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)度泵的安裝與(yǔ)試運(yùn)轉 installation and commissioning 高粘度泵的支座或法蘭與(yǔ)其驅動電(diàn)機應(yīng)采用共同的安(ān)裝基礎,基礎、法(fǎ)蘭或(huò)支(zhī)座均需(xū)具有(yǒu)足夠的剛(gāng)度,以減小(xiǎo)齒輪(lún)泵運轉時(shí)産生的振動和噪聲。電動(dòng)機(jī)與(yǔ)齒輪(lún)泵(bèng)須(xū)用(yòng)彈(dàn)性聯(lián)軸器連接,同(tóng)軸(zhóu)度小于0.1毫米,傾(qīng)斜角(jiǎo)不得大于1度。安(ān)裝(zhuāng)聯軸器(qì)時(shí)不得用(yòng)錘敲(qiāo)打,以免傷害齒(chǐ)輪泵的(de)齒輪等(děng)零件(jiàn)。若用帶輪(lún)、鍊輪等驅動時(shí)應設托(tuō)架支承(chéng),以防(fáng)主動(dòng)齒輪(lún)軸承(chéng)受徑向力(lì)。緊固齒輪(lún)泵、電動機(jī)的(de)地腳螺(luó)釘時,螺(luó)釘(dìng)受力(lì)應均勻(yún),連接(jiē)可(kě)靠。用手轉動聯(lián)軸器時,應(yīng)感覺到齒(chǐ)輪泵能夠(gòu)輕(qīng)松地轉動,沒(méi)有卡緊(jǐn)等(děng)異常(cháng)現象(xiàng)出現(xiàn),然後(hòu)才可以配(pèi)管。高(gāo)粘度(dù)齒輪泵的(de)吸(xī)油管(guǎn)道内徑(jìng)應足(zú)夠大,并避免狹窄通道或急劇拐彎(wān)、彎頭,去除不(bú)必要的(de)閥門、附件,盡可(kě)能地(dì)降低(dī)泵的安裝高度,縮短(duǎn)吸油管道的長(zhǎng)度,以(yǐ)減少(shǎo)壓力損失(shī)。管(guǎn)接頭等(děng)元件(jiàn)的(de)密封要(yào)良好,以防止空氣侵(qīn)入(rù),從而控(kòng)制氣穴與(yǔ)氣蝕(shí)的發生。在開始(shǐ)運轉前,往齒輪(lún)泵的殼體(tǐ)内灌(guàn)滿待輸送的液體,便(biàn)于安全動。若環境溫(wēn)度低(dī)于冰點,應預先(xiān)向泵内通(tōng)入熱(rè)蒸汽,進行預熱處理,然後(hòu)才可(kě)啟動齒輪泵。齒(chǐ)輪泵的旋(xuán)轉方向要與進(jìn)、出油(yóu)口相符(fú)。齒(chǐ)輪泵(bèng)若是(shì)第(dì)一(yī)次運(yùn)行,或長期閑置(zhì)後再使用,最好(hǎo)在空(kōng)載或小負荷情(qíng)況(kuàng)下先跑合一小時(shí)左右(yòu)。如果在跑(pǎo)合階(jiē)段預先覺(jiào)出異常溫(wēn)升、洩(xiè)漏、振(zhèn)動和(hé)噪聲(shēng)時,應機檢(jiǎn)查。高粘度(dù)泵的(de)出口管路(lù)上還(hái)應當設置(zhì)安全閥等(děng)保護(hù)裝置,這樣(yàng)一旦(dàn)泵的出口通道發生堵塞,就可(kě)以打(dǎ)開(kāi)安(ān)全閥卸壓。對(duì)于需要(yào)正反轉的高粘(zhān)度齒(chǐ)輪泵,其進(jìn)出(chū)口管路上均(jun1)需設置安全閥(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.
