●高粘度泵優點：

　　轉(zhuan)子泵的軸向位置(zhì)可調，不需要拆泵(bèng)。

　　泵采用模塊化設(she)計，可根據不同的(de)使用要求更換不(bu)㊙️同部件。可選夾層(céng)結構，以方便對泵(bèng)加熱或冷卻💋，可以(yǐ)選擇是否💘帶安全(quán)閥，可以選擇不同(tong)的密封形式，詳見(jian)密封結構圖。泵的(de)各個❄️零件可以選(xuan)用不同的材質以(yǐ)适應具體使用要(yào)求。

　　不同的使用條(tiáo)件，泵的結構形式(shi)可能不同，具體應(ying)用🎯請向廠👉家或本(ben)公司客戶代表咨(zi)詢。需要指出的是(shi)泵的轉速愈❄️高，泵(beng)🥰的磨損愈嚴重，液(ye)體中如含有🏒磨料(liào)物質，泵的材料應(yīng)選用耐磨材質，在(zai)此種工況下，泵的(de)壓‼️力和轉速都應(ying)降低，高溫條件下(xia)，則應增加泵的間(jiān)隙，并采用耐熱材(cai)料 。

　　流動穩定：流量(liang)與齒輪轉速成正(zhèng)比，與壓力無關

　　流(liu)動平穩：沒有脈動(dong)和壓力波峰，不會(hui)産生管道顫動。

　　多(duo)功能性：僅僅通過(guo)調整轉子軸的位(wèi)置，同一台泵‼️既可(ke)㊙️以出來稀釋溶液(yè)又可以出來瀝青(qīng)，糖漿，樹脂，聚合物(wu)等高粘度液體。

　　可(ke)逆性：可以通過改(gai)變齒輪的旋轉方(fāng)向使液體反向㊙️流(liú)動，兩種方向都能(néng)充分發揮泵的性(xìng)能

　　自吸性：由泵産(chan)生高真空，允許在(zài)最大自吸高度實(shi)現快速自吸，取決(jué)于泵送液體的物(wù)理特性（溫度，蒸汽(qì)壓力，粘💔度等）。

　　建議(yi)性：隻有兩個活動(dong)部件：主動輪和動(dòng)輪，隻有一🔞個軸封(feng)。

　　堅固的重載結構(gòu)：低轉速。特大球軸(zhóu)承的外部軸承座(zuò)可⭐以承受🌏軸向和(he)徑向負載。

　　磨損率(lǜ)低：由于主動輪和(hé)從動齒輪不成倍(bèi)數關系。這🧑🏾‍🤝‍🧑🏼就意味(wèi)着磨損可以被均(jun1)勻的分散在每個(gè)齒輪上。因為一🚶‍♀️個(ge)齒🏃‍♀️輪上㊙️的每一個(gè)齒輪接觸另一個(gè)齒輪上的🔞每一個(ge)齒輪的次數一樣(yang)。

磨損調節系統：轉(zhuan)子邊緣的磨損可(kě)以通過調整轉子(zǐ)軸的位💞置來補償(chang)。這樣，即使在有相(xiàng)當大的磨損♍的情(qíng)況下，也可以保證(zhèng)泵的穩定性。

　　維護(hu)簡單，維護率低：不(bú)用移動泵，管道或(huo)泵驅動裝置👈就可(ke)以進行檢查和調(diao)節。

　　互動性：标準組(zǔ)件的設計可實現(xiàn)不同材料和特性(xìng)零部件之間的替(ti)換。例如：有多種軸(zhou)封系統可供選擇(zé)，還🈲可以安裝帶夾(jiá)套的外殼和軸蓋(gài)來代替标準✊部件(jian)。

　　端口位置可改變(bian)：泵殼可在軸承箱(xiang)上旋轉以從不同(tóng)位置✉️處吸排液體(tǐ)。

　　預熱：加熱夾套或(huò)是與外殼鑄成一(yi)體，或是安裝在端(duān)蓋上，或是🎯安裝在(zài)填料壓蓋上。

　　旁路(lù)安全閥：旁路安全(quán)閥安裝在泵上并(bìng)且容易調節，在有(you)些型🎯号的泵上采(cǎi)取雙重安全閥并(bìng)帶加熱夾套。

●NYP高粘(zhān)度泵的進出口

　　泵(beng)進出口的型式

　　常(cháng)規泵進出口尺寸(cùn)相同，進出口呈垂(chuí)直布置，從驅動🈲機(ji)向泵頭方向看為(wéi)右進上出。也可根(gen)據客戶需要，加工(gong)成水平進出口型(xing)或左進上出型。連(lian)接方式有法蘭型(xíng)和螺紋型.

　　泵進出(chu)口負荷

　　泵在安裝(zhuāng)時，應限制泵的進(jìn)出口所承受的管(guǎn)路負荷。螺紋🌈聯接(jiē)的管接頭不得承(chéng)受負荷，否則會使(shi)泵的聯接管産生(sheng)松動或旋緊力矩(jǔ)（管螺紋聯接處不(bú)允許有⛱️旋緊或松(sōng)動的扭矩，以免）影(ying)響管路的聯接效(xiào)果。

●NYP高粘度泵的起(qǐ)動

　　泵在起動過程(chéng)中應特别注意以(yǐ)下幾個問題：

　　起動(dong)前要檢查下列内(nei)容：

　　檢查泵、齒輪箱(xiāng)和電機的對中程(chéng)度；

　　檢查過濾器中(zhōng)有沒有焊皮和金(jīn)屬渣；

　　檢查各連接(jiē)部位連接是否緊(jin)固；

　　檢查管路壓在(zai)泵上的力和力矩(jǔ)是否超過給定的(de)數值，如果溫度較(jiao)高，還應檢查管路(lu)是否有膨脹節；

　　檢(jian)查電氣連接的正(zhèng)确性及電機的額(é)定值，并檢查電機(ji)㊙️轉動方向是否正(zheng)确；

　　檢查泵的轉動(dong)方向是否正确；

　　如(rú)有安全閥，安全閥(fá)安裝必須正确，

　　檢(jian)查泵軸是否轉動(dong)靈活；

　　泵的内部不(bu)能是幹的，特别是(shì)需要自吸的時候(hòu)，應向泵🐇内灌注🌈一(yī)些油或輸送的液(ye)體；

　　泵組裝時在零(líng)件的表面有防護(hù)液，如果這種液體(ti)不能和泵送液體(tǐ)相容，則必須清洗(xi)；

　　最好在管路上安(ān)裝壓力表和真空(kōng)表，方便觀察泵的(de)工作狀态；

　　檢查機(ji)械密封箱是否注(zhù)滿液體；

　　檢查管路(lu)的閥門是否打開(kāi)；

　　如果用内燃機驅(qū)動，請在起動發動(dòng)機前保持離合器(qi)脫開；

　　泵起動後，檢(jian)查液體是否進入(ru)到泵中，泵是否工(gong)作正常，如果長時(shí)間無液體進入泵(bèng)中，應停機檢查泵(bèng)及管路。

●高粘度齒(chǐ)輪泵并不能産生(sheng)壓力，它隻是輸出(chu)流量。壓力低或無(wu)壓力，說💋明高粘度(du)齒 輪泵沒有吸入(rù)液體或洩漏嚴重(zhòng)。High viscosity gear pump does not generate pressure, it is only the output flow.Pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious.

　　電動機輸出功率(lǜ)偏小、齒 輪泵排量(liàng)選得過大或壓力(lì)調得過高時，也會(hui)造成壓力不足 當(dāng)然，壓力表損壞或(huo)壓力表節流孔堵(du)塞💚時也顯示不出(chū)壓力，此時可換裝(zhuang)一個新的壓力❄️表(biǎo)檢查。Small motor output power, gear wheel pump capacity to choose too large or pressure too high, can cause stress Pressure gauge damage or pressure gauge orifice jams, of course, also could not show pressure, can change a new pressure gauge to check at this time.

　　如果确認泵(beng)無流量輸出，可能(neng)是由于泵安裝有(yǒu)誤🐪、泵的轉♋向🧑🏽‍🤝‍🧑🏻不對(duì)，或吸人側(進液口(kou)及吸液管道)堵塞(sāi)、出口止回閥裝反(fan)或卡死了，也有可(ke)能是驅動軸斷裂(lie)💃🏻了。If confirmed that no flow pump output, could be turned to the pumps due to pump installation is wrong, wrong, or suction side (liquid into the mouth and suck liquid pipeline jam, export check valve installed backwards, or card is dead, it is possible that the drive shaft fracture.

　　高粘度泵在轉(zhuǎn)速過低時會引起(qi)出液量不足，這種(zhǒng)🏒現象往往是由于(yu)泵的驅動裝置打(da)滑或功率不足所(suo)緻。此時應檢查齒(chi)💯 輪泵的實際轉速(su)、泵與電動機的聯(lian)接及功率匹配情(qing)況等。High viscosity pump in low speed can cause insufficient quantity of produced liquid, this phenomenon is often due to the slippage of the pump drive or insufficient power.Check the gear wheel pump at this time of the actual speed, pump and motor connection and power matching, etc.

● 高粘度泵開(kāi)機準備

　　在開始運(yùn)轉前，往齒輪泵的(de)殼體内灌滿待輸(shu)送的液體，便于安(ān)全啟動。若環境溫(wen)度低于冰點，應預(yu)先向泵内通入熱(re)蒸汽，進行預熱處(chu)理，然後才可啟動(dong)齒輪泵。高粘度泵(bèng)的旋轉方向要與(yǔ)進、出油口相符。齒(chǐ)輪泵若是第一次(ci)運行，或長期閑置(zhi)後再使用，最好在(zài)空載或小負❌荷🔴情(qing)況下先跑合一小(xiao)時左右。如果在跑(pǎo)🌈合階段預先覺⚽察(chá)出異常⭐溫升、洩漏(lòu)、振動和噪聲時，應(yīng)停機檢查。高粘度(dù)齒輪泵的支座或(huò)法蘭與其驅動電(diàn)機應采用共同的(de)安裝基礎🏃‍♀️，基礎、法(fǎ)蘭或支座均需具(ju)有足夠的剛度，以(yǐ)減小齒輪泵運轉(zhuǎn)時産生的振動和(hé)噪聲。電動機與齒(chǐ)輪泵須用彈性聯(lián)軸器連接，同軸度(du)小于0.1毫米，傾斜角(jiǎo)不得大于1度。安裝(zhuang)聯軸器時不得用(yòng)錘敲打，以免傷害(hài)齒輪泵的齒輪等(deng)零件。若用帶輪、鍊(lian)輪等驅動時應設(shè)托架支承，以🛀🏻防主(zhǔ)動齒輪軸承受徑(jìng)向力。緊固齒輪泵(beng)、電動機的地腳螺(luo)釘時，螺釘受力應(ying)均勻，連接可靠。用(yong)手轉動聯軸器時(shí)，應感覺到齒輪泵(beng)能夠輕松地轉動(dong)，沒有卡緊等異常(cháng)現象出現，然後才(cái)可以配管。High viscosity pump before starting work, to gear pump casing filled with liquid, facilitate safe launch.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.The direction of rotation of the pump with high viscosity, 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 detect abnormal temperature rise, leakage, vibration and noise, should stop check.High viscosity gear pump bearing or flange should adopt a common drive motor installationFoundation, 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 of the gear pump gearAnd other parts.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.

     高粘度(dù)齒輪泵的吸油管(guan)道内徑應足夠大(da)，并避免狹窄通道(dao)或急劇拐彎、減少(shǎo)♍彎頭，去除不必要(yào)的閥門、附件，盡可(ke)能地降低泵的安(ān)裝高度，縮短吸油(you)管道的長度，以減(jian)♈少壓力損失。管接(jiē)頭等元件的密封(feng)要良好，以防止空(kong)氣侵入，從而控制(zhi)氣穴與氣蝕的發(fā)生。止回閥與🍉安全(quán)閥在齒輪泵的輸(shu)出管路上最好安(ān)裝一個止回閥。這(zhè)樣在檢修泵及輸(shū)出🌈管道時，系統中(zhong)的液體不會發生(sheng)倒流。齒輪泵帶負(fù)荷停車時，亦可防(fáng)止泵倒轉而在其(qí)輸出管道内⭐産生(sheng)局部真空。應當注(zhù)意，出口止回閥不(bu)能裝反🌂或出現卡(ka)✂️死現象。高👌粘度泵(bèng)的出口管路上還(hai)應當設置安全閥(fá)等保護裝置，這樣(yang)一旦泵的出口通(tōng)道🤞發生堵塞，就可(kě)以打開安全閥卸(xiè)壓。安全閥可以與(yǔ)泵體或泵蓋鑄成(chéng)一體，也可以單獨(dú)裝配。對于需要正(zhèng)反轉的高粘度齒(chi)輪泵，其進出口管(guǎn)路上均需設置安(ān)全閥。High viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp turn, reducing elbow, 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.Check valve and relief valve on the output of the gear pump tube had better install a check valve.In the overhaul pump and output pipe, the system of fluid backflow will not occur.Gear pump to stop loading machine, can be in the output pipe to prevent pump reverse, and create a partial vacuum.It should be noted that the outlet check valve cannot be installed backwards or stuck.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.The relief valve can be cast and pump body and pump cover, also can separate assembly.For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.

   高粘度泵是(shì)輸送高粘度液體(tǐ)的齒輪泵，應做到(dào)在較低的功耗、較(jiao)少的洩漏、較大的(de)壓力下輸出最多(duō)👨‍❤️‍👨的流量。在确定所(suo)要輸送的介質時(shi)，應該嚴格遵循産(chan)品㊙️說明書上的規(guī)定，盡量使用廠家(jia)推薦的流體介質(zhi)，并注意考慮系統(tǒng)的工作溫度範圍(wéi)。當希望在❓某一較(jiào)寬的溫度範圍内(nei)使用時，輸送介♋質(zhì)的粘度指數應該(gāi)高些。輸送介質不(bu)僅是能量傳🌐遞的(de)中介，而且也是潤(run)滑、密封及傳熱介(jiè)質。液體粘度過高(gāo)會增加内💋摩擦阻(zǔ)力，降低輸出功率(lǜ)，浪費能量，并産生(shēng)過高的系😍統溫度(du).高粘度齒輪泵的(de)出口管路上應當(dāng)設置安全閥等保(bǎo)護裝置，這樣一旦(dàn)泵的出😍口通道發(fā)生堵塞，就可以打(da)開安全閥卸壓。對(dui)于需要💁正反轉的(de)🔴高粘度齒輪泵，其(qi)進出口管路上均(jun)需設置安全閥。High viscosity pump is conveying liquid with high viscosity gear pump, should be in lower power consumption, less leakage, under the pressure of large output the most traffic.When determining to conveying medium, we should strictly follow the provisions of the product manuals on use manufacturers recommend fluid as far as possible, and pay attention to consider the system operating temperature range.When you want to use in a wide temperature range, medium viscosity index should be higher.Medium is not only the energy transfer intermediary, but also lubrication, sealing and heat transfer medium.Liquid viscosity is too high will increase internal friction resistance, lower output power, waste of energy, and generate high temperature system. High viscosity gear pump outlet pipe shall set up relief valve or other protective device on the road, so 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.
