我公司(sī)生産的(de)NYP高粘度(du)泵用作(zuò)高粘度(du)打膠泵(bèng)是非常(cháng)合适的(de)泵☔從結(jié)構上看(kàn):自吸性(xìng)能強，适(shì)用于輸(shu)送不含(han)固體顆(kē)粒和纖(xian)維的粘(zhān)稠液體(tǐ)，甚至是(shi)半固體(tǐ)狀态的(de)液體，最(zui)高輸送(sòng)粘度達(da)到3*105厘泊(bo)。具有體(ti)積小、重(zhòng)量輕、脈(mò)動小、噪(zao)音低、運(yùn)轉平穩(wen)、壽命長(zhang)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(du)泵工作(zuò)原理： 高(gao)粘度泵(beng)是容積(ji)式内齧(niè)合齒輪(lun)泵，主動(dòng)齒輪（外(wai)轉子）帶(dai)動被動(dong)齒輪（内(nèi)轉子）旋(xuán)轉時，不(bu)斷産🌍生(sheng)封閉🈲的(de)空間，在(zài)吸油區(qu)齒輪逐(zhu)漸脫離(li)齧合而(er)液體不(bu)斷地充(chōng)滿齒間(jiān)💃🏻并被帶(dài)到出油(yóu)區，齒輪(lún)在出油(yóu)區☎️進入(ru)齧合時(shi)液體被(bèi)排出。兩(liang)個旋轉(zhuan)齒輪的(de)共同作(zuo)用，形成(chéng)一個穩(wen)定的體(ti)🔞積排量(liàng)，沒🈚有脈(mò)動。由♈于(yú)泵是完(wán)全對稱(chēng)的，泵可(kě)以反轉(zhuǎn)，液流方(fang)向也随(sui)之改變(biàn)。但應注(zhù)🧡意，泵的(de)轉向可(ke)能受到(dao)密封或(huo)泵内其(qí)它結構(gòu)的限制(zhi)，用㊙️戶有(yǒu)反轉要(yao)求時應(ying)在訂貨(huo)時做出(chu)說明。 ●高(gāo)粘度泵(beng)優點： 泵(bèng)采用模(mo)塊化設(she)計，可根(gēn)據不同(tong)的使用(yòng)要求更(gèng)換不同(tóng)部🤞件。可(kě)🐉選夾層(céng)結構，以(yi)方便對(duì)泵加熱(re)或冷卻(què)，可以選(xuan)擇是否(fou)帶安✍️全(quan)閥，可以(yi)選擇不(bu)同的密(mi)封形式(shi)，詳見🔞密(mì)封結構(gòu)圖。泵🈲的(de)各個零(ling)件可💰以(yǐ)選用不(bú)同🐅的材(cái)質以适(shi)應具體(ti)使用要(yao)求。 不同(tong)的使用(yòng)條件，泵(bèng)的結構(gou)形式可(kě)能不同(tóng)，具體應(yīng)用請☎️向(xiàng)廠家或(huo)本公司(sī)客戶代(dài)表咨詢(xún)。需要指(zhi)出的是(shì)泵的轉(zhuan)速愈高(gao)，泵的磨(mo)損愈嚴(yán)重，液體(ti)中如含(han)有磨料(liao)物質，泵(bèng)的材料(liao)應📱選用(yòng)耐磨材(cai)質，在此(cǐ)種工況(kuàng)下，泵的(de)壓力和(hé)轉速都(dou)應降低(di)，高溫條(tiao)件下，則(ze)應增⭕加(jia)泵的間(jiān)隙，并采(cǎi)用耐熱(re)材料 。 流動平(píng)穩：沒有(you)脈動和(hé)壓力波(bō)峰，不會(hui)産生管(guan)道顫動(dòng)。
可逆(nì)性：可以(yǐ)通過改(gai)變齒輪(lún)的旋轉(zhuan)方向使(shi)液體反(fǎn)向流動(dong)，兩種❓方(fāng)向都能(neng)充分發(fā)揮泵的(de)性能 建議性(xing)：隻有兩(liǎng)個活動(dong)部件：主(zhǔ)動輪和(he)動輪，隻(zhi)有一個(gè)軸封。 堅(jian)固的重(zhong)載結構(gòu)：低轉速(su)。特大球(qiu)軸承的(de)外部軸(zhóu)承座可(kě)以承受(shòu)軸向和(hé)徑向負(fu)載。 磨損(sun)率低：由(you)于主動(dong)輪和從(cong)動齒輪(lún)不成倍(bei)數關系(xi)。這☎️就意(yì)🔱味着磨(mó)損可以(yi)被均勻(yún)的分散(san)在每個(gè)齒輪上(shang)。因為一(yi)⭐個齒輪(lún)上的每(měi)一個齒(chǐ)輪接觸(chu)另一個(ge)齒📧輪上(shang)的每一(yī)個⭕齒輪(lun)的次數(shù)一樣。 磨(mó)損調節(jiē)系統：轉(zhuǎn)子邊緣(yuan)的磨損(sun)可以通(tong)過調整(zheng)轉子軸(zhou)的位🔴置(zhi)🔞來補償(chang)。這樣，即(ji)使在有(you)相當大(dà)的磨損(sun)的情況(kuàng)下，也可(kě)以保證(zhèng)泵的穩(wěn)定性。 維(wei)護簡單(dan)，維護率(lü)低：不用(yòng)移動泵(beng)，管道或(huo)泵驅動(dòng)裝置就(jiù)可以進(jìn)行檢查(cha)和調節(jie)。 互動性(xìng)：标準組(zǔ)件的設(shè)計可實(shí)現不同(tong)材料和(he)特性🏃♀️零(ling)部件之(zhi)間的替(tì)換。例如(ru)：有多種(zhong)軸封系(xi)統可供(gòng)選擇，還(hái)可以安(an)裝❌帶夾(jiá)套的外(wài)殼和軸(zhóu)蓋來代(dai)替标準(zhun)😄部件。 端(duan)口位置(zhi)可改變(biàn)：泵殼可(ke)在軸承(chéng)箱上旋(xuán)轉以從(cong)不♋同位(wei)置處吸(xī)㊙️排液體(tǐ)。 預熱：加(jia)熱夾套(tào)或是與(yu)外殼鑄(zhu)成一體(ti)，或是安(ān)裝在端(duān)蓋上，或(huò)是安裝(zhuang)在填料(liao)壓蓋上(shàng)。 旁路安(ān)全閥：旁(páng)路安全(quán)閥安裝(zhuāng)在泵上(shàng)并且容(rong)易調節(jie)，在有🛀🏻些(xiē)型号的(de)泵上采(cai)取雙重(zhòng)安全閥(fa)并帶加(jiā)熱夾套(tao)。
1, select the work pressure 高粘度(dù)泵額定(dìng)的壓力(lì)是指泵(bèng)連續工(gōng)作時的(de)最高許(xǔ)用壓力(li)，而其工(gong)作壓力(li)則決定(ding)于外部(bu)負載，安(an)裝和調(diao)試的壽(shou)命與其(qí)工作壓(ya)力直接(jiē)相關。對(duì)于不頻(pin)繁工作(zuò)的齒輪(lún)泵，其工(gong)作壓力(li)可取為(wéi)泵的額(é)定壓力(lì)，考慮到(dào)産品質(zhì)量✊不同(tóng)💰，最好将(jiāng)額定壓(ya)力降低(dī)20%～30%使用。對(dui)于經常(cháng)工作于(yú)較高壓(ya)力下的(de)齒輪泵(bèng)，其工作(zuò)壓力應(yīng)比泵的(de)額定壓(ya)力低～2個(ge)壓力級(ji)。石油化(hua)工設備(bèi)常常是(shi)小時連(lian)續運轉(zhuǎn)，這時泵(beng)的工作(zuò)壓力應(ying)該取得(dé)比額定(dìng)壓力低(di)得多，且(qiě)工作轉(zhuan)速也應(ying)該低于(yu)額定轉(zhuǎn)速。如果(guǒ)高粘度(du)齒輪泵(beng)的工作(zuo)壓力調(diào)整過高(gao)，則會使(shǐ)齒輪泵(bèng)在超負(fù)荷下運(yun)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. ●高粘(zhān)度泵的(de)安裝與(yǔ)試運轉(zhuǎn) Installation and commissioning 高粘度(dù)泵的支(zhī)座或法(fa)蘭與其(qí)驅動電(dian)機應采(cai)用共同(tong)的安✊裝(zhuang)基🈲礎，基(jī)礎、法蘭(lán)或支座(zuo)均需具(jù)有足夠(gòu)的🌐剛度(du)，以減小(xiǎo)齒輪泵(bèng)運轉時(shi)産生的(de)振動和(he)噪聲。電(diàn)動機與(yu)齒輪泵(bèng)須用彈(dan)性聯軸(zhou)器連接(jie)，同軸度(dù)小于0.1毫(hao)米，傾斜(xie)角不得(de)大于1度(dù)。安裝聯(lián)軸器時(shí)不得用(yong)錘敲打(dǎ)，以免傷(shāng)害齒輪(lún)泵的齒(chǐ)輪等零(líng)件。若用(yong)帶輪、鍊(liàn)輪等驅(qu)動時應(ying)設托架(jià)支承，以(yi)防主動(dong)齒輪軸(zhóu)承受徑(jìng)向力。緊(jǐn)固齒輪(lun)泵、電動(dòng)機的地(dì)腳螺釘(dìng)時，螺釘(ding)受力應(ying)均勻，連(lian)接可靠(kào)。用手轉(zhuan)動聯軸(zhóu)器時，應(yīng)感覺到(dào)齒輪泵(bèng)能夠輕(qing)松地轉(zhuǎn)動，沒有(yǒu)卡緊等(deng)異常現(xiàn)象出現(xian)，然後才(cai)可以配(pèi)🔴管。高粘(zhan)度齒輪(lún)泵的吸(xī)油管道(dào)内徑應(yīng)足夠大(dà)，并避免(miǎn)狹窄通(tōng)道或急(jí)劇拐彎(wān)、彎💁頭，去(qù)除不必(bì)要的閥(fá)門、附件(jiàn)，盡可能(neng)地降低(di)泵的安(an)裝高度(du)，縮㊙️短吸(xi)油管道(dao)的長度(du)，以減少(shao)壓力損(sun)失。管接(jiē)頭等元(yuan)件的密(mì)封要良(liang)好，以防(fáng)止空氣(qi)侵入，從(cong)而控制(zhì)氣穴與(yu)氣蝕的(de)發生。在(zai)開始運(yun)轉前🔞，往(wǎng)齒輪泵(bèng)的殼體(ti)内灌滿(man)待輸送(sòng)的液體(ti)，便于安(ān)全動。若(ruò)環境溫(wēn)度低于(yu)冰❌點，應(ying)預先向(xiang)泵内通(tong)入熱蒸(zheng)汽，進行(hang)預👈熱處(chu)理，然後(hou)才可啟(qǐ)動齒輪(lún)泵。齒輪(lún)泵的旋(xuán)轉方向(xiàng)要與進(jìn)、出油口(kǒu)相符。齒(chǐ)輪泵若(ruo)是第一(yī)次運行(háng)，或長期(qī)閑置後(hou)再使用(yòng)，最好在(zai)空載或(huò)小負荷(hé)🍓情況下(xià)先跑合(hé)一小時(shi)左右。如(ru)果在跑(pǎo)㊙️合階段(duan)預先覺(jiao)出異常(cháng)溫升、洩(xiè)漏、振動(dòng)和噪聲(shēng)時，應機(ji)檢查。高(gāo)粘度泵(beng)的出口(kou)管路上(shang)還應👄當(dāng)設置安(ān)全閥等(deng)保護裝(zhuang)置，這樣(yang)一旦泵(bèng)的出口(kou)通道發(fa)生堵塞(sai)，就可以(yǐ)打開🤩安(an)全閥卸(xiè)壓🛀。對于(yu)需要正(zhèng)反轉的(de)高粘度(dù)齒輪泵(bèng)，其進出(chū)口管路(lù)上均需(xu)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.
