我公(gōng)司生産的NYP高(gao)粘度泵用作(zuo)高粘度打膠(jiao)泵是非常合(he)适的泵從結(jie)構上看:自吸(xi)性能強，适用(yong)于輸送🙇‍♀️不含(han)固體💛顆粒和(he)纖💃🏻維的粘稠(chóu)液體，甚至是(shi)半固體狀态(tài)的液體，最高(gāo)輸送粘度達(dá)到3*105厘泊。具有(you)體積小、重量(liang)輕、脈動小、噪(zao)音低、運轉平(píng)穩💚、壽命長👈等(děng)優點。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(dù)泵工作原理(li)：

　　高粘度泵是(shì)容積式内齧(niè)合齒輪泵，主(zhu)動齒輪（外轉(zhuan)子）帶動被動(dòng)齒輪（内轉子(zǐ)）旋轉時，不斷(duan)産生封閉的(de)空間，在吸油(you)區齒輪逐漸(jian)脫離齧合而(er)液🐕體不斷地(dì)充滿齒間并(bìng)被帶到出油(you)區，齒輪在出(chū)油區♌進入齧(niè)合時液體被(bèi)排出。兩個旋(xuán)轉齒輪的🧑🏾‍🤝‍🧑🏼共(gòng)同作用，形成(chéng)一個穩定的(de)體積排量，沒(mei)♍有脈動。由于(yú)泵是完全對(duì)稱的，泵可以(yǐ)反轉，液流方(fang)向也随之改(gǎi)變。但應注意(yi)，泵的轉向可(ke)能受到密封(feng)或泵内其它(tā)結構的限制(zhì)，用戶有反轉(zhuǎn)要求時應在(zai)訂貨時做㊙️出(chū)⭕說明。　　

●高粘度(dù)泵優點：

　　轉子(zi)泵的軸向位(wèi)置可調，不需(xū)要拆泵。

　　泵采(cǎi)用模塊化設(she)計，可根據不(bú)同的使用要(yào)求更換不同(tong)♋部件。可選夾(jia)層結構，以方(fāng)便對泵加熱(rè)或冷卻，可以(yi)選擇是否📱帶(dai)安全閥，可以(yi)選擇不同的(de)密封形式，詳(xiáng)見密封結構(gou)圖。泵的各個(gè)零件可以選(xuǎn)用不同的材(cai)質以适應具(ju)體🌈使用要求(qiu)。

　　不同的使用(yòng)條件，泵的結(jie)構形式可能(néng)不同，具體應(yīng)用🍉請向廠💔家(jia)或本公司客(ke)戶代表咨詢(xun)。需要指出的(de)是泵的轉速(sù)愈高，泵的磨(mó)損愈嚴重，液(ye)體中如含有(yǒu)磨料物質，泵(beng)的材料應選(xuan)用耐磨材質(zhì)，在此種工況(kuàng)下，泵的壓🧑🏾‍🤝‍🧑🏼力(li)和轉速都應(ying)降低，高溫條(tiáo)件下，則應增(zēng)☁️加泵的間隙(xì)，并采用耐熱(re)材料 。

　　流動穩(wen)定：流量與齒(chǐ)輪轉速成正(zheng)比，與壓力無(wú)關

　　流動平穩(wen)：沒有脈動和(he)壓力波峰，不(bu)會産生管道(dao)顫☀️動。

　　多功能(néng)性：僅僅通過(guo)調整轉子軸(zhóu)的位置，同一(yī)台泵既可以(yǐ)出來🔆稀釋溶(rong)液又可以出(chu)來瀝青，糖漿(jiang)，樹脂，聚合物(wù)等高粘度液(yè)體。

　　可逆性：可(ke)以通過改變(bian)齒輪的旋轉(zhuǎn)方向使液體(tǐ)反向流動，兩(liang)🔆種方向都能(neng)充分發揮泵(bèng)的性能

　　自吸(xī)性：由泵産生(shēng)高真空，允許(xǔ)在最大自吸(xī)高度實現快(kuai)速自吸，取決(jué)于泵送液體(ti)的物理特性(xing)（溫度，蒸汽壓(ya)力，粘度等）。

　　建(jian)議性：隻有兩(liǎng)個活動部件(jiàn)：主動輪和動(dong)輪，隻有一個(ge)🍓軸封。

　　堅固的(de)重載結構：低(dī)轉速。特大球(qiú)軸承的外部(bu)軸承座❄️可以(yǐ)承受軸向和(he)徑向負載。

　　磨(mo)損率低：由于(yú)主動輪和從(cóng)動齒輪不成(chéng)倍數關系💃🏻。這(zhè)就意味着磨(mó)損可以被均(jun1)勻的分散在(zài)每個齒輪上(shang)。因為一個齒(chi)輪上的每一(yi)個齒輪接觸(chu)另一個齒輪(lun)上的每一個(gè)齒輪的次數(shù)一🔞樣。

磨損調(diao)節系統：轉子(zi)邊緣的磨損(sun)可以通過調(diao)整轉子軸的(de)位置來補償(chang)。這樣，即使在(zai)有相當大的(de)磨損的情況(kuang)下，也可以保(bao)證泵的穩定(ding)性。

　　維護簡單(dan)，維護率低：不(bu)用移動泵，管(guǎn)道或泵驅動(dòng)裝置就🏃可以(yǐ)進行檢查和(he)調節。

　　互動性(xìng)：标準組件的(de)設計可實現(xian)不同材料和(he)特性零部件(jiàn)之間的替換(huàn)。例如：有多種(zhǒng)軸封系統可(ke)供選擇，還可(ke)以安裝🍓帶夾(jiá)套的外殼和(hé)軸蓋來代替(tì)标準部件。

　　端(duān)口位置可改(gai)變：泵殼可在(zai)軸承箱上旋(xuán)轉以從不同(tóng)位置🔆處吸排(pái)液體。

　　預熱：加(jiā)熱夾套或是(shi)與外殼鑄成(cheng)一體，或是安(an)裝在端蓋🌍上(shang)，或是安裝在(zai)填料壓蓋上(shàng)。

　　旁路安全閥(fá)：旁路安全閥(fá)安裝在泵上(shàng)并且容易調(diao)😄節，在有些型(xing)号的泵上采(cai)取雙重安全(quan)閥并帶加熱(re)夾套。●高粘度(du)泵的工作壓(yā)力的選定

　　1, select the work pressure

　　高(gao)粘度泵額定(ding)的壓力是指(zhi)泵連續工作(zuò)時的最高許(xǔ)🤩用壓✔️力，而其(qi)工作壓力則(zé)決定于外部(bù)負載，安裝和(hé)調試的壽命(ming)與其工作壓(yā)力直接相關(guan)。對于不頻繁(fán)工作的齒輪(lun)泵，其工作壓(yā)力可取為泵(bèng)的額定壓力(lì)，考慮到産品(pin)質💁量不同，最(zui)☔好将額定壓(yā)力降低20%～30%使用(yong)。對于經常工(gōng)作于較高壓(yā)力下的齒輪(lún)泵，其工作壓(ya)力應比泵的(de)額定壓力低(di)1～2個壓力級。石(shi)油化工設備(bei)常常是24小時(shí)連續運轉，這(zhe)時泵的工作(zuo)壓力應該取(qǔ)得比額定壓(ya)力低得🌍多，且(qiě)工作轉速也(yě)應該低于額(e)定轉速。如果(guo)⚽高粘度齒輪(lún)泵的工作壓(ya)力調整過高(gao)，則會使齒輪(lún)泵在超負荷(he)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(zhan)度泵的安裝(zhuāng)與試運轉

　　Installation and commissioning

　　高(gāo)粘度泵的支(zhi)座或法蘭與(yu)其驅動電機(jī)應采用共同(tóng)的安裝基礎(chǔ)，基礎、法蘭或(huo)支座均需具(ju)有足夠的剛(gāng)度，以減小齒(chǐ)輪泵運轉時(shí)産生的振動(dong)和噪聲。電動(dong)機與齒輪泵(bèng)須用彈性聯(lián)軸器連接，同(tóng)軸度小于0.1毫(hao)米，傾斜角不(bu)得大于1度。安(ān)裝聯軸器時(shi)不得用錘敲(qiāo)打，以免傷害(hai)齒輪泵的齒(chǐ)輪等零件。若(ruò)用帶輪、鍊輪(lun)等驅動時應(yīng)設托架支承(cheng)🌏，以😘防主動齒(chǐ)輪軸承受徑(jìng)向力。緊固齒(chǐ)輪泵、電動機(jī)的地腳螺釘(dìng)時，螺釘受力(li)應均勻，連接(jie)可靠。用手轉(zhuǎn)動聯軸器時(shí)，應感覺到齒(chi)輪泵能夠輕(qīng)松地轉動，沒(mei)有卡緊等異(yi)常現象出現(xiàn)，然後才可以(yǐ)配管🏃🏻‍♂️。高粘度(dù)齒輪泵的吸(xī)油管道内徑(jing)應足夠大，并(bìng)避免狹窄通(tōng)道或急劇🈲拐(guai)彎、彎頭，去除(chú)不必要的閥(fá)門、附件，盡可(ke)能地降低泵(beng)的安裝高度(dù)，縮短吸油管(guan)道的長度，以(yǐ)減少壓力損(sun)失。管接頭等(deng)元件的密封(feng)要良好，以防(fang)止空氣侵入(ru)，從而控制氣(qi)穴與氣蝕的(de)發生。在開始(shi)運轉前💋，往齒(chǐ)輪泵的殼體(tǐ)内灌滿待輸(shu)送的液體，便(biàn)于安全動。若(ruò)環境溫🆚度低(di)💰于冰點，應預(yu)先向泵内通(tong)入熱蒸汽，進(jìn)行預熱處理(lǐ)，然👈後才🆚可啟(qi)動齒輪泵。齒(chǐ)輪泵的旋轉(zhuan)方向要與進(jin)、出油口相符(fu)。齒輪泵若是(shì)第一次運行(háng)，或長期閑置(zhi)後再使用，最(zui)好在空載或(huo)小負🏃🏻‍♂️荷情況(kuang)下先跑合一(yi)小時左右。如(rú)果在跑合階(jie)段預💋先覺出(chu)異常溫升、洩(xiè)漏、振動和噪(zào)聲時，應💚機檢(jiǎn)查🐪。高粘度泵(beng)的出口管路(lu)上還應🧑🏾‍🤝‍🧑🏼當設(shè)置安全閥等(děng)保護裝置，這(zhè)樣一旦泵的(de)出口通道發(fā)生堵塞，就可(kě)以打開安全(quan)閥卸壓🎯。對于(yu)需要正反轉(zhuǎn)的高粘度齒(chi)輪泵，其進出(chū)口管路上均(jun1)需設置安全(quán)閥。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.
