●高粘度泵優點(dian)：

　　轉子泵的軸向(xiang)位置可調，不需(xu)要拆泵。

　　泵采用(yòng)模塊化設計，可(kě)根據不同的使(shǐ)用要求更換不(bu)♈同部件。可🧡選夾(jiá)層結構，以方便(bian)對泵加熱或冷(lěng)卻，可以選擇是(shi)否帶安全閥♍，可(ke)以選擇不同的(de)密封形式，詳見(jiàn)🔞密封結構圖。泵(beng)💛的各個零件可(ke)以選用不同⁉️的(de)材質以适應具(ju)體使用要求。

　　不(bú)同的使用條件(jiàn)，泵的結構形式(shi)可能不同，具體(ti)應用請向廠⚽家(jiā)或本公司客戶(hù)代表咨詢。需要(yao)指出的是泵的(de)轉速愈高，泵💛的(de)磨損愈嚴重，液(ye)體中如含有磨(mo)料物質，泵的材(cái)料應選用耐磨(mó)材質，在此種工(gōng)況下，泵的壓力(lì)和轉速🚶‍♀️都應降(jiàng)低，高溫條件下(xia)，則應增加泵的(de)間隙，并采用耐(nài)熱材料 。

　　流動穩(wěn)定：流量與齒輪(lún)轉速成正比，與(yǔ)壓力無關

　　流動(dong)平穩：沒有脈動(dong)和壓力波峰，不(bú)會産生管道顫(chan)🚶‍♀️動。

　　多功能性：僅(jǐn)僅通過調整轉(zhuǎn)子軸的位置，同(tóng)一台泵既可✊以(yǐ)出來☂️稀釋溶液(ye)又可以出來瀝(lì)青，糖漿，樹脂，聚(ju)合物等高粘🌐度(dù)液體。

　　可逆性：可(kě)以通過改變齒(chǐ)輪的旋轉方向(xiang)使液體反向流(liú)動🐇，兩種方向都(dōu)能充分發揮泵(bèng)的性能

　　自吸性(xing)：由泵産生高真(zhen)空，允許在最大(dà)自吸高度實現(xiàn)快速☁️自吸，取決(jué)于泵送液體的(de)物理特性（溫度(du)，蒸汽壓力，粘⭐度(dù)等🍉）。

　　建議性：隻有(yǒu)兩個活動部件(jiàn)：主動輪和動輪(lún)，隻有一個軸🈲封(feng)。

　　堅固的重載結(jie)構：低轉速。特大(dà)球軸承的外部(bu)軸承座可以承(cheng)受軸向和徑向(xiang)負載。

　　磨損率低(di)：由于主動輪和(hé)從動齒輪不成(chéng)倍數關系。這就(jiu)意味着磨損可(ke)以被均勻的分(fèn)散在每個齒輪(lun)上。因為一個齒(chǐ)☁️輪上的每一個(ge)齒輪接觸另一(yī)個齒輪上的每(mei)一個齒輪的次(ci)數一樣。

磨損調(diao)節系統：轉子邊(bian)緣的磨損可以(yi)通過調整轉子(zǐ)軸‼️的✔️位置來補(bǔ)償。這樣，即使在(zai)有相當大的磨(mó)損的情況下，也(ye)可以保👌證泵📱的(de)穩定性。

　　維護簡(jiǎn)單，維護率低：不(bú)用移動泵，管道(dao)或泵驅動裝🌏置(zhi)就可😍以🐉進行檢(jiǎn)查和調節。

　　互動(dong)性：标準組件的(de)設計可實現不(bú)同材料和特性(xing)零部件之間的(de)替換。例如：有多(duo)種軸封系統可(ke)供選擇，還可以(yǐ)🌈安裝帶夾套的(de)外殼和軸蓋來(lai)代替标準🛀🏻部件(jiàn)。

　　端口位置可改(gǎi)變：泵殼可在軸(zhóu)承箱上旋轉以(yi)從不同位置處(chù)吸🛀排液體。

　　預熱(re)：加熱夾套或是(shì)與外殼鑄成一(yī)體，或是安裝在(zai)端蓋上，或☀️是安(ān)裝在填料壓蓋(gài)上。

　　旁路安全閥(fa)：旁路安全閥安(ān)裝在泵上并且(qiě)容易調節，在😍有(you)些型号的泵上(shàng)采取雙重安全(quán)閥并帶加熱⁉️夾(jia)套。

●NYP高粘度泵的(de)進出口

　　泵進出(chu)口的型式

　　常規(guī)泵進出口尺寸(cùn)相同，進出口呈(cheng)垂直布置，從驅(qū)動💯機向泵頭方(fāng)向看為右進上(shang)出。也可根據客(kè)戶需要，加工成(cheng)水平進出口型(xíng)🐕或左進上出型(xíng)。連接方式有法(fǎ)蘭型和螺紋型(xíng).

　　泵進出口負荷(he)

　　泵在安裝時，應(yīng)限制泵的進出(chū)口所承受的管(guan)路負荷。螺紋聯(lian)接的管接頭不(bú)得承受負荷，否(fǒu)則會使泵的聯(lián)接管産生松動(dong)或旋緊力矩（管(guǎn)螺紋聯接處不(bu)允許有旋緊或(huo)松動的扭矩，以(yi)免）影響🥰管路的(de)聯接效果。

●NYP高粘(zhan)度泵的起動

　　泵(bèng)在起動過程中(zhōng)應特别注意以(yǐ)下幾個問題：

　　起(qǐ)動前要檢查下(xia)列内容：

　　檢查泵(beng)、齒輪箱和電機(ji)的對中程度；

　　檢(jiǎn)查過濾器中有(you)沒有焊皮和金(jin)屬渣；

　　檢查各連(lián)接部位連接是(shi)否緊固；

　　檢查管(guan)路壓在泵上的(de)力和力矩是否(fǒu)超過給定的數(shù)值，如果溫度較(jiao)高，還應檢查管(guǎn)路是否有膨脹(zhang)節；

　　檢查電氣連(lian)接的正确性及(jí)電機的額定值(zhí)，并檢查電機轉(zhuan)動方向是否正(zheng)确；

　　檢查泵的轉(zhuǎn)動方向是否正(zheng)确；

　　如有安全閥(fa)，安全閥安裝必(bi)須正确，

　　檢查泵(bèng)軸是否轉動靈(líng)活；

　　泵的内部不(bú)能是幹的，特别(bie)是需要自吸的(de)時候，應向泵内(nèi)灌注一些油或(huo)輸送的液體；

　　泵(beng)組裝時在零件(jiàn)的表面有防護(hu)液，如果這種液(yè)體🈲不🌈能和泵送(sòng)液體相容，則必(bi)須清洗；

　　最好在(zai)管路上安裝壓(ya)力表和真空表(biao)，方便觀察泵👌的(de)❌工作❓狀态；

　　檢查(cha)機械密封箱是(shì)否注滿液體；

　　檢(jiǎn)查管路的閥門(men)是否打開；

　　如果(guo)用内燃機驅動(dòng)，請在起動發動(dong)機前保持離合(hé)器脫開；

　　泵起動(dòng)後，檢查液體是(shì)否進入到泵中(zhong)，泵是否工作正(zhèng)常，如果長🙇‍♀️時間(jian)無液體進入泵(beng)中，應停機檢查(cha)泵及管路。

●高粘(zhan)度齒輪泵并不(bu)能産生壓力，它(tā)隻是輸出流量(liang)。壓力低或無壓(ya)力，說明高粘度(dù)齒 輪泵沒有吸(xī)入液體或洩漏(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.

　　電動機輸(shū)出功率偏小、齒(chi) 輪泵排量選得(de)過大或壓力㊙️調(diào)得過高時，也會(hui)造成壓力不足(zú) 當然，壓力表損(sǔn)壞或壓力表節(jiē)流孔堵塞時也(ye)顯示不出壓力(lì)，此時可換裝一(yi)個新的壓力表(biao)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(rèn)泵無流量輸出(chū)，可能是由于泵(bèng)安裝有誤💚、泵的(de)轉向不對，或吸(xī)人側(進液口及(jí)吸液管道)堵塞(sāi)、出口止回閥裝(zhuang)反或卡死了，也(yě)有可能是驅動(dong)軸斷裂了。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(zhān)度泵在轉速過(guo)低時會引起出(chu)液量不足，這種(zhong)現象往🈲往是由(yóu)于泵的驅動裝(zhuang)置打滑或功率(lü)不足所緻。此時(shi)🍓應檢♉查齒 輪泵(beng)的實際轉速、泵(beng)與電動機🌍的聯(lián)接及功率匹配(pei)情況等。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(dù)泵開機準備

　　在(zài)開始運轉前，往(wǎng)齒輪泵的殼體(tǐ)内灌滿待輸送(sòng)的液體，便于安(an)全啟動。若環境(jing)溫👌度💚低于💋冰點(dian)，應預先向泵内(nèi)通入熱蒸汽，進(jìn)行預熱處理，然(ran)後♍才可👅啟動齒(chi)輪泵。高粘度泵(beng)的旋轉方向要(yao)與進、出油口相(xiàng)符。齒輪泵若是(shi)第一次運行，或(huò)長期閑置後再(zài)使用，最好在空(kong)載或小負荷情(qíng)況下先跑合一(yī)小時左右。如果(guo)在跑合階段預(yu)先覺察出🏒異常(cháng)溫升、洩漏、振動(dong)和噪聲時，應停(ting)機檢查。高粘度(dù)齒輪泵的支座(zuò)或法蘭與其驅(qū)動電機應采用(yong)共同的安裝基(ji)礎，基礎、法🈲蘭或(huò)支座均需具有(you)足夠的剛度，以(yi)減小齒輪泵運(yun)轉時産生的振(zhen)動和噪聲。電動(dong)機與齒輪泵須(xu)用彈性聯軸器(qi)連接，同軸度小(xiǎo)于0.1毫米，傾斜角(jiǎo)不得大于1度。安(ān)裝聯軸器時不(bu)得用錘敲打，以(yǐ)免傷害齒輪泵(bèng)的齒輪等零件(jian)。若用帶輪、鍊輪(lun)等驅動時應設(shè)托架支承，以防(fáng)主動齒輪軸承(chéng)受徑向力。緊固(gu)齒輪泵、電動機(ji)的地腳螺釘時(shi)，螺釘受力應均(jun)勻，連接可靠。用(yong)手轉動聯🤩軸器(qì)時，應感覺到齒(chǐ)輪泵能夠輕松(song)地轉動，沒有卡(kǎ)緊等異常現象(xiang)出現，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.

     高粘度(dù)齒輪泵的吸油(yóu)管道内徑應足(zú)夠大，并避免狹(xiá)窄通道或急劇(jù)拐彎、減⭕少彎頭(tóu)，去除不必要的(de)閥門、附件，盡可(ke)能地降低泵的(de)安✉️裝高🏃度，縮短(duǎn)吸油管道的長(zhǎng)度，以減少壓力(lì)損失。管接頭等(deng)元件的密封要(yao)良好，以防止空(kong)氣侵入，從而控(kong)制氣穴與氣蝕(shi)的發生🔅。止回閥(fa)與安全閥在齒(chi)輪泵的輸出管(guǎn)路上最好安裝(zhuang)一個止回閥。這(zhe)樣在檢修泵及(ji)輸❓出管道時，系(xì)統中的液體不(bú)會發生倒流。齒(chi)輪泵帶負荷停(ting)車時，亦可防止(zhǐ)泵倒轉而在其(qi)輸出管道内❗産(chan)生局部真空。應(yīng)當注意，出口止(zhǐ)回閥不能裝反(fan)或出現卡死現(xiàn)象。高粘度泵的(de)出口管路上還(hái)應當設置安全(quan)閥等♍保護裝置(zhi)，這樣🏃🏻‍♂️一旦泵的(de)出口通道發生(sheng)堵塞，就可以打(dǎ)開安全閥卸壓(ya)。安全㊙️閥可以與(yu)泵體或泵蓋鑄(zhù)成一體，也可以(yi)單獨裝配。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 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(bèng)是輸送高粘度(dù)液體的齒輪泵(beng)，應做到在較低(dī)的功耗、較少的(de)洩漏、較大的壓(ya)力下輸出🌈最☀️多(duō)的流量。在确定(dìng)所要輸送的介(jie)質時，應該嚴格(gé)遵循産品說明(míng)書上的規定，盡(jìn)量使用廠家推(tuī)薦的流👣體介質(zhì)，并注意考慮系(xi)統的工作溫度(dù)範圍。當希望在(zài)某一較寬的溫(wen)度範圍内使用(yòng)時，輸送介🐪質的(de)粘度指🙇‍♀️數應該(gai)高些。輸送介質(zhì)不🌐僅是能量傳(chuan)遞的中介，而且(qiě)也是潤滑、密封(fēng)及傳熱介質。液(yè)體粘🈲度過高會(huì)增加内🐉摩擦阻(zǔ)力，降低輸出功(gong)率，浪費能量，并(bing)産生過高的系(xì)統溫度.高粘度(du)齒輪泵的出口(kou)管路上應當設(shè)置安全閥等保(bǎo)護裝置，這樣🧑🏽‍🤝‍🧑🏻一(yi)旦泵的出口通(tong)道發生堵塞，就(jiu)可以打開安全(quán)閥卸壓。對于需(xu)要📧正反㊙️轉的高(gao)粘度齒輪泵，其(qí)進出口管路上(shàng)均需設置安全(quan)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.
