●高(gao)粘度泵優點(diǎn)：

　　轉子泵的軸(zhou)向位置可調(diào)，不需要拆泵(beng)。

　　泵采用模塊(kuai)化設計，可根(gēn)據不同的使(shǐ)用要求更換(huan)不同部💛件🌈。可(kě)🧑🏽‍🤝‍🧑🏻選夾層結構(gou)，以方便對泵(beng)加熱或冷卻(que)，可以選擇是(shi)否帶安全閥(fá)，可以選擇不(bú)同的密封形(xíng)式，詳見密封(feng)結構圖。泵的(de)各個零件可(ke)以選用不同(tong)的材質以适(shi)應具體使用(yong)要求。

　　不同的(de)使用條件，泵(bèng)的結構形式(shì)可能不同，具(jù)體應用請向(xiàng)廠家或本公(gōng)司客戶代表(biao)咨詢。需要指(zhǐ)出的🈲是泵的(de)轉速愈高，泵(beng)的磨損愈嚴(yan)重，液體中如(ru)含有磨料物(wu)質，泵的材料(liao)應選用耐磨(mo)材質，在此種(zhǒng)工況下，泵的(de)壓力和轉速(sù)都應降低，高(gāo)溫條件下，則(zé)應增加泵的(de)間隙，并采用(yong)耐熱材料 。

　　流(liú)動穩定：流量(liang)與齒輪轉速(su)成正比，與壓(ya)力無關

　　流動(dòng)平穩：沒有脈(mò)動和壓力波(bō)峰，不會産生(shēng)管道顫動。

　　多(duō)功能性：僅僅(jǐn)通過調整轉(zhuan)子軸的位置(zhì)，同一台泵既(jì)可👈以⚽出來稀(xi)釋溶液又可(ke)以出來瀝青(qing)，糖漿，樹脂，聚(ju)合🍉物等高粘(zhān)度液體。

　　可逆(nì)性：可以通過(guò)改變齒輪的(de)旋轉方向使(shǐ)液體反向流(liú)動，兩種⚽方向(xiàng)都能充分發(fā)揮泵的性能(néng)

　　自吸性：由泵(beng)産生高真空(kōng)，允許在最大(da)自吸高度實(shí)現快👄速自吸(xi)，取決于泵送(song)液體的物理(li)特性（溫度，蒸(zheng)汽壓🍓力，粘度(du)等）。

　　建議性：隻(zhī)有兩個活動(dong)部件：主動輪(lún)和動輪，隻有(yǒu)一個軸🌈封。

　　堅(jian)固的重載結(jie)構：低轉速。特(tè)大球軸承的(de)外部軸承座(zuo)👌可以承受軸(zhóu)向和徑向負(fu)載。

　　磨損率低(di)：由于主動輪(lún)和從動齒輪(lún)不成倍數關(guan)系。這就意味(wèi)着磨損可以(yi)被均勻的分(fèn)散在每個齒(chǐ)輪🚶上。因為一(yi)個齒💃輪上的(de)每♈一個齒輪(lun)接觸另一個(ge)齒輪上的每(mei)一個齒輪的(de)次數一樣。

磨(mó)損調節系統(tong)：轉子邊緣的(de)磨損可以通(tong)過調整轉🐪子(zi)軸⭕的位置來(lai)補償。這樣，即(ji)使在有相當(dāng)大的磨損的(de)情況下，也可(kě)以保證泵的(de)穩定性。

　　維護(hù)簡單，維護率(lǜ)低：不用移動(dong)泵，管道或泵(bèng)驅動裝置就(jiù)可以☂️進行檢(jian)查和調節。

　　互(hu)動性：标準組(zǔ)件的設計可(kě)實現不同材(cai)料和特性零(ling)部件之間的(de)替換。例如：有(you)多種軸封系(xi)統可供選擇(zé)，還可以安裝(zhuang)帶夾套的外(wài)殼和軸蓋來(lái)代替标準㊙️部(bu)件。

　　端口位置(zhì)可改變：泵殼(ké)可在軸承箱(xiang)上旋轉以從(cong)不同位置處(chù)吸排液體。

　　預(yu)熱：加熱夾套(tao)或是與外殼(ke)鑄成一體，或(huo)是安裝在✊端(duan)蓋上，或是安(an)裝在填料壓(yā)蓋上。

　　旁路安(an)全閥：旁路安(an)全閥安裝在(zai)泵上并且容(róng)易調節，在有(you)些🚶‍♀️型号的泵(beng)上采取雙重(zhong)安全閥并帶(dai)加熱夾套。

●NYP高(gao)粘度泵的進(jin)出口

　　泵進出(chū)口的型式

　　常(cháng)規泵進出口(kou)尺寸相同，進(jin)出口呈垂直(zhí)布置，從驅動(dòng)機向🛀泵頭方(fang)向看為右進(jin)上出。也可根(gen)據客戶需✂️要(yao)，加工成♉水平(píng)進出口型或(huo)左進上出型(xíng)。連接方式🈚有(yǒu)法蘭💞型和螺(luo)紋型.

　　泵進出(chu)口負荷

　　泵在(zai)安裝時，應限(xiàn)制泵的進出(chū)口所承受的(de)管路負荷。螺(luo)紋聯接的管(guǎn)接頭不得承(cheng)受負荷，否則(ze)會使泵的聯(lian)接管産生松(song)動或旋緊力(li)矩（管螺紋聯(lian)接處不允許(xǔ)有旋緊或松(sōng)動的扭矩，以(yi)免）影響管路(lu)的聯接👌效果(guǒ)。

●NYP高粘度泵的(de)起動

　　泵在起(qi)動過程中應(yīng)特别注意以(yi)下幾個問題(tí)：

　　起動前要檢(jiǎn)查下列内容(róng)：

　　檢查泵、齒輪(lun)箱和電機的(de)對中程度；

　　檢(jiǎn)查過濾器中(zhong)有沒有焊皮(pi)和金屬渣；

　　檢(jian)查各連接部(bu)位連接是否(fou)緊固；

　　檢查管(guǎn)路壓在泵上(shang)的力和力矩(ju)是否超過給(gei)定的數💜值，如(ru)果溫🤩度較高(gao)，還應檢查管(guǎn)路是否有膨(peng)脹節；

　　檢查電(dian)氣連接的正(zhèng)确性及電機(ji)的額定值，并(bing)檢查電機轉(zhuǎn)動方向是否(fou)正确；

　　檢查泵(bèng)的轉動方向(xiàng)是否正确；

　　如(rú)有安全閥，安(an)全閥安裝必(bì)須正确，

　　檢查(cha)泵軸是否轉(zhuǎn)動靈活；

　　泵的(de)内部不能是(shì)幹的，特别是(shi)需要自吸的(de)時候，應向🛀泵(beng)🏃内灌注一些(xie)油或輸送的(de)液體；

　　泵組裝(zhuāng)時在零件的(de)表面有防護(hu)液，如果這種(zhong)液體不能和(he)泵送液體相(xiàng)容，則必須清(qīng)洗；

　　最好在管(guǎn)路上安裝壓(yā)力表和真空(kōng)表，方便觀察(chá)泵的🏃🏻‍♂️工作狀(zhuang)态；

　　檢查機械(xiè)密封箱是否(fou)注滿液體；

　　檢(jian)查管路的閥(fá)門是否打開(kai)；

　　如果用内燃(ran)機驅動，請在(zai)起動發動機(jī)前保持離合(hé)器脫開；

　　泵起(qǐ)動後，檢查液(yè)體是否進入(rù)到泵中，泵是(shi)否工作正常(cháng)🔞，如😘果🧡長🚩時間(jiān)無液體進入(ru)泵中，應停機(jī)檢查泵及管(guǎn)路。

●高粘度齒(chi)輪泵并不能(neng)産生壓力，它(ta)隻是輸出流(liu)量。壓力低或(huo)無壓力♉，說明(míng)高粘度齒 輪(lun)泵沒有吸入(ru)液體或洩漏(lou)嚴重。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(ji)輸出功率偏(piān)小、齒 輪泵排(pái)量選得過大(da)或壓力💞調得(dé)🏃🏻過高時，也會(huì)造成壓力不(bú)足 當然，壓力(li)表損壞或壓(ya)力🆚表節流孔(kong)堵塞時也顯(xiǎn)示不出壓力(li)，此時可換裝(zhuāng)一個新的壓(ya)力表檢查。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(rú)果确認泵無(wu)流量輸出，可(kě)能是由于泵(beng)安裝有誤、泵(beng)的轉向不🌂對(dui)，或吸人側(進(jìn)液口及吸液(yè)管道)堵塞、出(chu)口止回閥裝(zhuāng)反或卡死了(le)，也有可能是(shì)驅動軸斷裂(liè)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(beng)在轉速過低(dī)時會引起出(chu)液量不足，這(zhè)種現象往往(wang)是由于泵的(de)驅動裝置打(dǎ)滑或功率不(bú)足所緻💛。此時(shi)應檢查齒 輪(lún)泵的實際轉(zhuǎn)速、泵與電動(dong)機的聯接及(jí)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(du)泵開機準備(bei)

　　在開始運轉(zhuan)前，往齒輪泵(beng)的殼體内灌(guàn)滿待輸送的(de)液體，便于安(ān)全啟動。若環(huán)境溫度低🔞于(yu)冰點，應預先(xian)向泵内通入(rù)熱蒸汽，進行(hang)預熱處理♋，然(ran)後才可啟動(dòng)齒輪泵。高粘(zhān)度泵的旋轉(zhuǎn)方向要與進(jin)、出油口相符(fu)。齒輪泵若是(shi)第一次運行(háng)，或長期閑置(zhì)後再使用，最(zui)好在空載⚽或(huò)小負🌈荷🔆情況(kuàng)下先跑合一(yi)小時左右。如(rú)果在跑合階(jie)❤️段預先覺察(chá)出異常溫升(sheng)、洩漏、振動和(he)噪聲時，應停(tíng)機檢查。高粘(zhan)度齒輪泵的(de)支座或法蘭(lan)與其驅動電(dian)機應采用共(gong)同的安裝基(jī)礎，基☂️礎、法蘭(lán)或支座均需(xu)具有足夠的(de)剛度，以減小(xiǎo)齒輪泵運轉(zhuǎn)時産生的振(zhen)動和噪聲。電(dian)動機與齒輪(lun)泵須用彈性(xìng)聯軸器連接(jiē)，同軸度小于(yú)0.1毫米，傾斜角(jiǎo)不得大于1度(du)。安裝聯軸器(qì)時不得用錘(chui)敲打，以免傷(shāng)害齒輪泵的(de)齒輪等零件(jiàn)。若用帶輪、鍊(lian)輪等驅動時(shi)應設托架❄️支(zhi)承，以防👅主動(dòng)齒輪軸承受(shòu)徑向力。緊固(gu)齒輪泵、電動(dong)機的地腳螺(luó)釘時，螺釘受(shou)力應均勻，連(lian)接可靠。用手(shǒu)轉動聯軸器(qi)時，應感覺到(dao)齒輪泵能夠(gou)輕松地轉動(dong)，沒有卡緊等(deng)異常現象出(chū)現，然後才可(kě)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(zhan)度齒輪泵的(de)吸油管道内(nei)徑應足夠大(da)，并避免狹窄(zhai)通道或急劇(ju)拐彎、減😄少彎(wān)頭，去除不必(bì)要的閥門、附(fù)件，盡可能地(dì)降低泵的安(an)裝高🚩度，縮短(duan)吸油管道的(de)長度，以減㊙️少(shao)壓力損失。管(guǎn)接頭等元件(jian)的密封要良(liáng)好，以防止空(kōng)氣侵入，從而(ér)控制🏃🏻氣穴與(yu)氣💋蝕的發生(sheng)。止回閥與安(ān)全閥在齒輪(lun)泵的輸出管(guǎn)路上最好安(ān)裝一個止回(hui)閥。這樣在檢(jian)修泵🈲及輸出(chu)管🌂道時，系統(tǒng)中的液體不(bú)會發生倒流(liu)。齒輪泵帶負(fu)荷停車時，亦(yi)可防止泵倒(dǎo)轉而在其輸(shū)出管道内産(chan)生局部真空(kōng)。應當注意，出(chu)口止回閥不(bu)能裝反或出(chu)現卡🐪死現象(xiàng)。高粘度泵的(de)出口管路上(shàng)還應當設置(zhì)安全閥等♌保(bao)護裝置，這樣(yàng)一旦泵的出(chu)口通道⚽發生(sheng)堵塞，就可以(yi)打開安全閥(fa)卸壓。安全閥(fa)可以與👅泵體(ti)或泵蓋鑄成(chéng)一體，也可以(yǐ)單獨裝配。對(dui)于需要正反(fǎn)轉的高粘度(dù)齒輪泵，其進(jìn)出口管路上(shang)均需設置安(an)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(du)泵是輸送高(gao)粘度液體的(de)齒輪泵，應做(zuo)到在較低的(de)功耗、較少的(de)洩漏、較大的(de)壓力下輸出(chu)最多的流量(liang)。在确定所要(yào)輸送的介質(zhi)時，應該嚴格(gé)遵循🥵産品說(shuo)明書上的規(gui)定，盡量使用(yòng)廠家推薦的(de)流體介質，并(bing)注意考慮系(xì)統的工作溫(wēn)度範圍。當希(xī)望在某一較(jiào)寬的溫度範(fan)圍内使用👌時(shi)，輸送介質的(de)粘度指數應(ying)該高些⭕。輸送(song)介質不僅是(shi)能量傳❓遞的(de)中介，而且也(ye)是潤滑、密封(fēng)及傳熱介質(zhi)。液體粘⛹🏻‍♀️度過(guò)高會🏒增加内(nei)摩擦阻力，降(jiàng)低輸出功率(lü)，浪費能量，并(bing)産生過高的(de)系👅統溫度.高(gāo)粘度齒輪泵(bèng)的出口管路(lù)上應當設置(zhì)安全閥等保(bao)護裝置，這樣(yang)一旦泵💯的🌈出(chū)口通道發生(sheng)堵塞，就可以(yi)打開安全閥(fá)卸壓🧑🏽‍🤝‍🧑🏻。對于需(xū)要正反轉的(de)高粘度齒輪(lún)泵，其進出口(kou)管路上均需(xu)設置安全閥(fá)。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.
