●高粘(zhān)度泵優點(dian)：

　　轉子泵的(de)軸向位置(zhì)可調，不需(xu)要拆泵。

　　泵(beng)采用模塊(kuai)化設計，可(ke)根據不同(tong)的使用要(yào)求更換不(bú)👣同部件☔。可(kě)選夾層結(jié)構，以方便(bian)對泵加熱(re)或冷卻，可(kě)以選擇是(shi)否帶安全(quán)閥🚩，可以選(xuǎn)擇不同的(de)密封形🏒式(shi)，詳見♈密封(fēng)結構圖。泵(bèng)的各個零(ling)件可以選(xuan)用不同的(de)材質以适(shi)應具體使(shi)用要求。

　　不(bu)同的使用(yong)條件，泵的(de)結構形式(shi)可能不同(tong)，具體應用(yong)請向廠家(jiā)或本公司(si)客戶代表(biǎo)咨詢。需要(yào)指出的是(shì)泵的轉速(sù)愈高，泵的(de)磨損愈嚴(yan)重，液體中(zhong)如含有磨(mo)料物質，泵(beng)的材料應(yīng)選用耐💰磨(mo)材質，在此(cǐ)種工況下(xia)，泵的壓力(lì)和轉速都(dou)應降低，高(gāo)溫條件下(xià)，則應增加(jia)泵的間隙(xi)，并采用耐(nai)熱材料 。

　　流(liu)動穩定：流(liú)量與齒輪(lún)轉速成正(zhèng)比，與壓力(li)無關

　　流動(dòng)平穩：沒有(you)脈動和壓(ya)力波峰，不(bu)會産生管(guan)道顫動。

　　多(duō)功能性：僅(jin)僅通過調(diào)整轉子軸(zhóu)的位置，同(tóng)一台泵既(ji)㊙️可🏃🏻‍♂️以出🏃🏻‍♂️來(lái)😍稀釋溶液(yè)又可以出(chu)來瀝青，糖(tang)漿，樹脂，聚(jù)合物等高(gao)粘度液體(tǐ)。

　　可逆性：可(kě)以通過改(gai)變齒輪的(de)旋轉方向(xiang)使液體反(fǎn)💰向🤩流動，兩(liang)種方向都(dōu)能充分發(fā)揮泵的性(xìng)能

　　自吸性(xìng)：由泵産生(shēng)高真空，允(yǔn)許在最大(da)自吸高度(du)實現快速(su)⭐自吸，取決(jue)于泵送液(yè)體的物理(li)特性（溫度(du)，蒸汽壓力(li)，粘度等）。

　　建(jiàn)議性：隻有(yǒu)兩個活動(dòng)部件：主動(dòng)輪和動輪(lun)，隻有一⛷️個(ge)🔴軸封。

　　堅固(gù)的重載結(jié)構：低轉速(su)。特大球軸(zhou)承的外部(bu)軸承座☁️可(ke)以承受軸(zhóu)向和徑向(xiàng)負載。

　　磨損(sun)率低：由于(yu)主動輪和(hé)從動齒輪(lún)不成倍數(shù)關系。這就(jiu)意味🔴着🈲磨(mó)損可以被(bei)均勻的分(fèn)散在每個(ge)齒輪上。因(yin)為一個齒(chǐ)輪上🏒的每(mei)一個齒輪(lun)接觸另一(yī)個齒輪上(shang)的每一個(ge)齒輪的次(ci)數一樣。

磨(mó)損調節系(xi)統：轉子邊(biān)緣的磨損(sǔn)可以通過(guo)調整轉子(zǐ)軸的位置(zhi)來補償。這(zhè)樣，即使在(zài)有相當大(dà)的磨損的(de)情況下，也(yě)可以保💚證(zhèng)泵的穩定(dìng)性。

　　維護簡(jian)單，維護率(lǜ)低：不用移(yi)動泵，管道(dào)或泵驅動(dong)裝🔴置⭐就可(ke)以進行檢(jiǎn)查和調節(jiē)。

　　互動性：标(biao)準組件的(de)設計可實(shí)現不同材(cai)料和特性(xing)零部件之(zhi)間的替換(huan)。例如：有多(duo)種軸封系(xi)統可供選(xuǎn)擇，還可以(yǐ)🛀安裝帶夾(jia)套的⛷️外殼(ké)和軸蓋來(lái)代替标準(zhun)部件。

　　端口(kou)位置可改(gai)變：泵殼可(ke)在軸承箱(xiang)上旋轉以(yi)從不同位(wèi)🏃🏻置處🚶‍♀️吸排(pái)液體。

　　預熱(re)：加熱夾套(tào)或是與外(wài)殼鑄成一(yi)體，或是安(ān)裝在端蓋(gai)上，或👌是安(an)裝在填料(liào)壓蓋上。

　　旁(pang)路安全閥(fa)：旁路安全(quan)閥安裝在(zai)泵上并且(qiě)容易調節(jie)😄，在‼️有些型(xíng)号的泵上(shàng)采取雙重(zhong)安全閥并(bìng)帶加熱💚夾(jia)套。

●NYP高粘度(dù)泵的進出(chu)口

　　泵進出(chu)口的型式(shi)

　　常規泵進(jìn)出口尺寸(cun)相同，進出(chu)口呈垂直(zhí)布置，從驅(qū)🐇動🙇‍♀️機向泵(bèng)頭方向看(kan)為右進上(shàng)出。也可根(gen)據客戶需(xū)💚要，加工成(chéng)水平進出(chū)口型或左(zuǒ)進上出型(xíng)。連接方式(shì)有法蘭型(xing)和螺紋型(xíng).

　　泵進出口(kǒu)負荷

　　泵在(zai)安裝時，應(yīng)限制泵的(de)進出口所(suǒ)承受的管(guan)路負荷🔞。螺(luó)紋聯接的(de)管接頭不(bu)得承受負(fù)荷，否則會(hui)使泵的聯(lian)接管産生(shēng)松動或旋(xuan)緊力矩（管(guǎn)螺紋聯接(jiē)處不允許(xu)有旋緊或(huò)☂️松動的扭(niǔ)矩，以免）影(yǐng)響管路的(de)聯接效果(guo)。

●NYP高粘度泵(bèng)的起動

　　泵(bèng)在起動過(guo)程中應特(tè)别注意以(yi)下幾個問(wèn)題：

　　起動前(qián)要檢查下(xià)列内容：

　　檢(jian)查泵、齒輪(lun)箱和電機(ji)的對中程(chéng)度；

　　檢查過(guò)濾器中有(you)沒有焊皮(pi)和金屬渣(zhā)；

　　檢查各連(lián)接部位連(lián)接是否緊(jǐn)固；

　　檢查管(guǎn)路壓在泵(beng)上的力和(he)力矩是否(fou)超過給定(ding)的數值，如(rú)果🥰溫度較(jiao)高，還應檢(jiǎn)查管路是(shi)否有膨脹(zhang)節；

　　檢查電(diàn)氣連接的(de)正确性及(jí)電機的額(é)定值，并檢(jiǎn)查電機轉(zhuǎn)動方向是(shi)否正确；

　　檢(jian)查泵的轉(zhuǎn)動方向是(shi)否正确；

　　如(ru)有安全閥(fá)，安全閥安(an)裝必須正(zhèng)确，

　　檢查泵(beng)軸是否轉(zhuǎn)動靈活；

　　泵(beng)的内部不(bu)能是幹的(de)，特别是需(xu)要自吸的(de)時候，應向(xiang)泵内✍️灌注(zhù)一些油或(huò)輸送的液(ye)體；

　　泵組裝(zhuang)時在零件(jian)的表面有(you)防護液，如(ru)果這種液(ye)體不能和(hé)泵送液體(ti)相容，則必(bì)須清洗；

　　最(zui)好在管路(lu)上安裝壓(ya)力表和真(zhen)空表，方便(biàn)觀察泵的(de)工💞作狀态(tai)；

　　檢查機械(xie)密封箱是(shì)否注滿液(yè)體；

　　檢查管(guǎn)路的閥門(men)是否打開(kai)；

　　如果用内(nei)燃機驅動(dong)，請在起動(dong)發動機前(qian)保持離合(hé)🍉器脫開；

　　泵(beng)起動後，檢(jiǎn)查液體是(shì)否進入到(dào)泵中，泵是(shì)否工作正(zheng)常，如果長(zhǎng)時間無液(yè)體進入泵(bèng)中，應停機(jī)檢查泵及(jí)管路。

●高粘(zhan)度齒輪泵(beng)并不能産(chǎn)生壓力，它(tā)隻是輸出(chu)流量。壓力(li)低或無壓(yā)力，說明高(gāo)🈲粘度齒 輪(lún)泵沒有吸(xī)入液體或(huo)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(shu)出功率偏(pian)小、齒 輪泵(bèng)排量選得(de)過大或壓(ya)🌈力調得過(guò)🍉高🛀🏻時，也會(huì)造成壓力(lì)不足 當然(ran)，壓力表損(sǔn)壞或✂️壓力(li)表節🤩流孔(kǒng)堵塞🔅時也(yě)顯示不出(chū)壓力，此時(shi)可換裝🔱一(yī)個新的壓(yā)力表檢查(cha)。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(liàng)輸出，可能(neng)是由于泵(beng)安裝有誤(wù)、泵🔞的✊轉向(xiàng)不對，或吸(xī)人側(進液(yè)口及吸液(ye)管道)堵塞(sāi)、出口止回(hui)閥裝反或(huò)卡死了，也(ye)有可能是(shì)驅動軸斷(duàn)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(zhan)度泵在轉(zhuǎn)速過低時(shi)會引起出(chu)液量不足(zu)，這種現象(xiang)往往是由(you)于泵的驅(qu)動裝置打(dǎ)滑或功率(lǜ)不足💜所緻(zhì)🏃‍♀️。此時應檢(jian)查齒 輪泵(beng)的實際轉(zhuan)速、泵與電(dian)動機的聯(lian)接👌及功率(lǜ)🌐匹配情況(kuang)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(zhǔn)備

　　在開始(shǐ)運轉前，往(wǎng)齒輪泵的(de)殼體内灌(guan)滿待輸送(song)的液體，便(biàn)于安全啟(qi)動。若環境(jìng)溫🔴度低于(yú)冰點，應預(yu)先向泵内(nèi)通入熱蒸(zhēng)汽，進行預(yù)熱處理，然(ran)後才可啟(qi)動齒輪泵(bèng)。高粘度泵(bèng)的旋轉方(fang)向要與進(jìn)、出油口相(xiàng)符。齒輪泵(bèng)若是第一(yi)次運行，或(huò)長期閑置(zhì)後再使用(yong)，最好在空(kōng)載或小負(fu)荷情況下(xia)先跑合一(yi)小時左右(you)。如果在跑(pǎo)合階🈲段預(yù)先覺察出(chū)異常溫升(sheng)、洩漏、振動(dong)和噪聲時(shi)，應停機檢(jiǎn)查。高粘度(du)齒輪泵的(de)支座或法(fǎ)蘭與其驅(qū)動電機應(yīng)采用共同(tóng)的安裝基(jī)🤩礎，基礎、法(fǎ)蘭或支座(zuo)均需具有(yǒu)足夠的剛(gang)度，以減小(xiǎo)齒輪泵運(yùn)轉時産生(shēng)的振動和(hé)噪聲。電動(dong)機與齒輪(lun)泵須用彈(dan)性聯軸器(qi)連接，同軸(zhou)度小于0.1毫(háo)米，傾斜角(jiǎo)不得大于(yu)1度。安裝聯(lián)軸器時不(bú)得用錘敲(qiāo)打，以免傷(shang)害齒輪泵(beng)的齒輪等(deng)零件。若用(yong)帶輪、鍊輪(lún)等驅動時(shi)應設托架(jià)支承，以防(fáng)主動齒輪(lun)軸承受徑(jìng)向力。緊固(gù)齒輪泵、電(dian)動機的地(dì)腳螺釘時(shí)，螺釘受力(lì)應均勻，連(lián)接可靠。用(yong)手轉動聯(lian)🔆軸器時，應(yīng)感覺到齒(chi)輪泵能夠(gòu)輕松地轉(zhuan)動，沒有卡(kǎ)緊等異常(chang)現象出現(xiàn)，然後才可(ke)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(gāo)粘度齒輪(lún)泵的吸油(yóu)管道内徑(jing)應足夠大(da)，并避免狹(xia)窄通道或(huo)急劇拐彎(wan)、減少彎頭(tou)，去除不必(bì)要的閥門(men)、附件，盡可(ke)能⛹🏻‍♀️地降低(di)泵💋的安裝(zhuang)高度，縮短(duan)吸油管道(dào)的長度，以(yi)減少壓力(li)🈚損失。管接(jiē)頭等元件(jiàn)的密封要(yào)良好，以防(fáng)止♈空氣侵(qīn)入，從而控(kòng)制氣穴與(yu)氣蝕的發(fa)生。止回閥(fa)與👨‍❤️‍👨安全閥(fa)在齒輪泵(bèng)的輸出管(guǎn)路上最好(hao)安裝一個(ge)止回閥。這(zhè)樣在檢修(xiū)泵🔞及輸出(chu)管道時，系(xi)統中的液(yè)體不會發(fā)生倒流。齒(chǐ)輪泵帶負(fu)荷停車時(shi)，亦可防止(zhǐ)泵倒轉而(ér)在其輸出(chu)管道内🔴産(chǎn)生局部真(zhen)空。應當注(zhu)意，出口止(zhǐ)回閥不能(néng)裝反或出(chu)現卡死現(xiàn)象。高粘度(du)泵的出口(kou)管路上還(hái)應當🔞設置(zhì)安全閥等(děng)保護裝置(zhi)，這樣一旦(dan)泵的出口(kǒu)通道⭐發生(shēng)堵塞，就可(ke)以打開安(an)全閥卸壓(yā)。安全閥可(kě)以與☀️泵體(tǐ)或泵蓋鑄(zhu)成一體，也(yě)可以單獨(dú)裝配。對于(yú)需要正反(fan)轉的高粘(zhān)度齒輪泵(beng)，其進出口(kǒu)管路上均(jun)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(zhan)度泵是輸(shū)送高粘度(dù)液體的齒(chi)輪泵，應做(zuo)到在較低(dī)的功耗、較(jiao)少的洩漏(lòu)、較大的壓(yā)力下輸出(chū)最🔴多的流(liu)量。在确定(dìng)所要輸送(sòng)的介質時(shí)，應該嚴格(ge)遵循産品(pin)說明書上(shàng)的規定，盡(jìn)量使用廠(chang)家推薦的(de)流體介質(zhì)，并注意考(kǎo)慮系統的(de)工作溫度(du)範圍⭐。當希(xī)望在某一(yi)較寬的溫(wen)度範圍内(nèi)使用👉時，輸(shu)送介質的(de)粘度指✊數(shu)應該高些(xie)。輸送介質(zhi)不僅是能(neng)量傳遞的(de)中介，而且(qie)也是潤滑(hua)、密封及傳(chuan)熱介質。液(yè)體粘度過(guò)高會增加(jia)内🈲摩擦阻(zǔ)力，降低輸(shū)出功率，浪(lang)費能量，并(bing)産生過高(gao)的系🌍統溫(wēn)度.高粘度(dù)齒輪泵的(de)出口管路(lù)上應當設(she)置安全閥(fá)等保護裝(zhuang)置，這樣一(yi)旦❌泵的㊙️出(chu)口通道發(fā)生堵塞，就(jiu)可以打開(kai)安全閥卸(xiè)壓。對于需(xū)要正反轉(zhuǎn)的🐉高粘度(du)齒輪泵，其(qi)進出口管(guan)路上均需(xū)設置安全(quán)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.
