我公司(si)生産的NYP高粘度(du)泵用作高粘度(dù)打膠泵是非常(cháng)合适的泵從結(jié)構上看:自吸性(xing)能強，适用于輸(shu)送不含固體顆(ke)粒和纖💛維的🌂粘(zhan)稠液體，甚至是(shì)半固體狀态的(de)液體，最🧑🏽‍🤝‍🧑🏻高輸送(song)粘度達到3*105厘泊(bo)。具有體積小、重(zhòng)量輕、脈動小、噪(zao)音低、運轉平穩(wěn)、壽命長等🎯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(zuo)原理：

　　高粘度泵(beng)是容積式内齧(nie)合齒輪泵，主動(dong)齒輪（外轉子）帶(dai)動被動齒輪（内(nei)轉子）旋轉時，不(bu)🆚斷産生封閉的(de)空間，在吸油區(qū)齒輪逐漸脫離(li)齧合而液✔️體不(bu)斷地充滿齒間(jian)并被帶到出油(you)區，齒輪在出油(yóu)區進入齧🙇‍♀️合時(shí)液體被排出。兩(liang)個旋轉齒輪的(de)共同作用🚶‍♀️，形成(cheng)一個穩定的體(ti)積排量，沒有脈(mo)動。由于泵是完(wán)全‼️對稱的，泵可(kě)以反轉，液流方(fang)向也随之👅改變(biàn)。但應注意，泵的(de)轉向可能受到(dao)密封或泵内其(qí)它結構的限制(zhi)，用戶有反轉要(yao)求時應在訂貨(huò)時做出說明。　　

●高(gāo)粘度泵優點：

　　轉(zhuǎn)子泵的軸向位(wei)置可調，不需要(yào)拆泵。

　　泵采用模(mo)塊化設計，可根(gēn)據不同的使用(yòng)要求更換不同(tong)部件。可選夾層(céng)結構，以方便對(dui)泵加熱或冷卻(que)，可以選擇是否(fǒu)帶安✂️全閥，可以(yǐ)選擇不同的密(mi)封形🈚式，詳見🧑🏽‍🤝‍🧑🏻密(mì)封結構圖。泵的(de)各個零件可以(yi)選用不同的材(cai)質以适應具體(ti)使用要求。

　　不同(tong)的使用條件，泵(beng)的結構形式可(kě)能不同，具體應(yīng)用請💃🏻向廠家或(huò)本公司客戶代(dài)表咨詢。需要指(zhi)出的是泵💘的轉(zhuǎn)速愈高，泵🧑🏾‍🤝‍🧑🏼的磨(mo)損愈嚴重，液體(ti)中如含有🤞磨料(liào)物質，泵的🙇🏻材料(liao)應選用耐💞磨材(cái)質，在此種工況(kuang)下，泵的壓力和(hé)轉速都應降低(di)，高溫條件💁下，則(zé)應增加泵的間(jian)隙，并采用耐熱(re)材料 。

　　流動穩定(ding)：流量與齒輪轉(zhuan)速成正比，與壓(ya)力無關

　　流動平(ping)穩：沒有脈動和(hé)壓力波峰，不會(huì)産生管道顫❗動(dong)。

　　多功能性：僅僅(jǐn)通過調整轉子(zi)軸的位置，同一(yi)台泵既可♊以出(chū)來稀釋溶液又(you)可以出來瀝青(qing)，糖漿，樹脂，聚合(hé)物等高粘度液(ye)體。

　　可逆性：可以(yǐ)通過改變齒輪(lun)的旋轉方向使(shi)液體反⭐向流動(dòng)，兩種方向都能(neng)充分發揮泵的(de)性能

　　自吸性：由(you)泵産生高真空(kong)，允許在最大自(zi)吸高度實現快(kuài)速自❤️吸，取決于(yú)泵送液體的物(wù)理特性（溫度，蒸(zhēng)🔴汽壓力，粘度等(děng)）。

　　建議性：隻有兩(liǎng)個活動部件：主(zhu)動輪和動輪，隻(zhi)有一個軸封。

　　堅(jian)固的重載結構(gou)：低轉速。特大球(qiú)軸承的外部軸(zhóu)承座可以承受(shou)軸向和徑向負(fù)載。

　　磨損率低：由(you)于主動輪和從(cóng)動齒輪不成倍(bei)數關系☂️。這就意(yì)味着磨損可以(yǐ)被均勻的分散(san)在每個齒輪🏃🏻上(shàng)。因為一個齒輪(lún)上🎯的每一個齒(chi)輪接觸另一個(ge)齒輪上的每一(yī)個齒輪的次數(shù)一樣。

磨損調節(jie)系統：轉子邊緣(yuan)的磨損可以通(tōng)過調整轉🛀🏻子軸(zhóu)⭕的位置來補償(chang)。這樣，即使在有(you)相當大的磨損(sun)的情況下，也可(kě)以保證泵☂️的穩(wen)定性。

　　維護簡單(dān)，維護率低：不用(yong)移動泵，管道或(huo)泵驅動裝置就(jiu)可以進行檢查(chá)和調節。

　　互動性(xìng)：标準組件的設(she)計可實現不同(tóng)材料和特性零(ling)部件之間的替(tì)換。例如：有多種(zhong)軸封系統可供(gong)選💞擇，還可以安(an)裝帶夾套的外(wài)殼和軸蓋來代(dài)替标準部件。

　　端(duan)口位置可改變(bian)：泵殼可在軸承(chéng)箱上旋轉以從(cóng)不同位置處吸(xi)排液體。

　　預熱：加(jia)熱夾套或是與(yu)外殼鑄成一體(tǐ)，或是安裝在端(duān)蓋🍓上，或是安裝(zhuang)在填料壓蓋上(shang)。

　　旁路安全閥：旁(páng)路安全閥安裝(zhuang)在泵上并且容(róng)易調節，在有些(xie)型号的泵上采(cǎi)取雙重安全閥(fa)并帶加熱夾套(tào)。●高粘度泵的工(gong)作壓力的選定(dìng)

　　1, select the work pressure

　　高粘度泵額定(dìng)的壓力是指泵(beng)連續工作時的(de)最高許用壓力(lì)❌，而🚶其工作壓力(li)則決定于外部(bu)負載，安裝❌和調(diào)試的壽命與其(qi)工作壓力直接(jie)相關。對于不頻(pín)繁工作的齒輪(lún)泵，其工作壓力(lì)可取為泵的額(e)定壓力，考慮到(dào)産品質量不同(tong)💃，最好将額定壓(ya)力降低20%～30%使用。對(dui)于經常工作于(yú)較高壓力下的(de)齒輪泵，其工作(zuo)壓力應比泵的(de)額定壓力低1～2個(gè)壓力級。石油化(huà)工設備常常是(shi)24小時連續運轉(zhuan)，這時泵的工作(zuò)壓力應該取得(de)比額定壓力低(dī)得‼️多，且工作轉(zhuǎn)速也應該低于(yu)額定轉速。如果(guǒ)高粘度齒輪泵(bèng)的工作壓力調(diào)整過高，則會使(shǐ)齒輪泵在超負(fù)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)度泵的安裝與(yǔ)試運轉

　　Installation and commissioning

　　高粘度(du)泵的支座或法(fa)蘭與其驅動電(dian)機應采用共🐆同(tóng)的安裝基礎，基(ji)礎、法蘭或支座(zuo)均需具有足夠(gou)的剛度，以減小(xiao)齒輪泵運轉時(shi)産生的振動和(hé)噪聲。電動機與(yu)齒輪泵須用彈(dàn)性聯軸器連接(jiē)，同軸度小于0.1毫(háo)米，傾斜角不得(de)大于1度。安裝聯(lián)軸器時不得用(yong)錘敲打，以免傷(shang)害齒輪泵的齒(chǐ)輪等零件。若用(yòng)帶輪、鍊輪等驅(qū)動時應設托架(jià)支承，以防主動(dòng)齒輪軸承受徑(jìng)向力。緊固齒輪(lun)泵、電動機的地(di)腳螺釘時，螺釘(ding)受力應均勻，連(lián)接可靠。用手轉(zhuǎn)動聯♊軸器時，應(yīng)感覺到齒輪泵(bèng)能夠輕松地轉(zhuan)動，沒有卡緊等(deng)異常現象出現(xiàn)，然後🛀才🌂可以配(pei)管。高粘度齒輪(lun)泵的吸油管道(dào)内徑應足夠大(dà)，并避免狹窄通(tōng)道或急劇拐🤞彎(wān)⁉️、彎頭，去除不必(bi)要的閥門、附件(jian)，盡可能地降低(dī)泵的安裝高度(du)，縮短吸油管道(dao)的長度，以減少(shǎo)壓力損失。管接(jie)頭等元件的密(mì)封♋要良好，以防(fang)止空氣🔴侵入，從(cong)而控制氣穴與(yu)氣蝕的發生。在(zai)開始運轉前💯，往(wang)齒輪泵的殼體(tǐ)内灌滿待輸送(song)的液體，便于安(an)全動。若環境溫(wēn)度低于冰點，應(ying)預先向泵内通(tong)入熱蒸汽，進行(hang)預熱處理，然🧡後(hòu)才可啟動齒輪(lun)泵。齒輪泵的旋(xuan)轉方向要與進(jìn)、出油口相符。齒(chǐ)輪泵若是第一(yī)次運行，或長期(qi)閑置後再使用(yong)，最好在空載⭐或(huò)小負荷情況下(xia)先跑合一小時(shí)左右。如果在跑(pǎo)合階段預先覺(jiao)出異常溫升、洩(xiè)漏、振動和噪聲(sheng)時，應機檢查🈲。高(gāo)粘度泵的出口(kǒu)管路上還應⁉️當(dāng)設置安全閥等(děng)保護裝置，這樣(yang)一旦泵的出口(kou)通道發生堵塞(sai)🍓，就可以打開安(ān)全閥卸壓。對于(yú)需要正反轉的(de)高粘度齒輪泵(bèng)，其進出口管路(lù)上均需設置安(ān)全閥。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.
