●高粘度泵使(shi)用時注意事(shi)項Matters needing attention when using high viscosity pump

　　進、出口管(guan)路的管徑必(bi)須和泵保持(chí)一緻；The diameters of inlet and outlet piping must be consistent with pump;

　　設計管(guan)路時應盡量(liàng)減少彎頭，且(qie)彎頭角度不(bú)宜過小，進口(kou)管線不宜過(guo)長，以免影響(xiang)自吸。

　　啟動前(qián)每個注油杯(bei)都應家潤滑(hua)油，且保證每(měi)天加油一次(cì)。

　　泵在工作前(qian)應該點動啟(qǐ)動電機，觀察(cha)轉向是否和(he)規定轉向一(yi)緻。

　　開機後觀(guan)察運轉是否(fǒu)正常，如有不(bú)正常噪音、特(tè)殊振動或溫(wen)升過高等情(qíng)況，應停機檢(jiǎn)查。

　　注意皮帶(dài)松緊是否恰(qià)當，每半年調(diào)整一次。　

●高粘(zhān)度泵工作原(yuán)理：

　　高粘度泵(beng)是容積式内(nèi)齧合齒輪泵(beng)，主動齒輪（外(wai)轉子）帶動被(bei)動齒輪（内轉(zhuǎn)子）旋轉時，不(bú)斷産生封🐅閉(bì)的空間，在吸(xī)油區齒輪逐(zhú)漸脫離齧合(he)而液㊙️體不♻️斷(duan)地充滿齒間(jiān)并被帶到出(chū)油區，齒輪在(zai)出油區進入(ru)齧合時液體(tǐ)被排出。兩個(ge)✌️旋轉齒輪的(de)共同作用，形(xing)成一個穩定(ding)的體積排量(liàng)，沒🚶‍♀️有脈動。由(yóu)于泵是完全(quan)對稱的，泵可(kě)🔅以反轉，液流(liu)方向也随之(zhi)改變。但應注(zhù)意，泵的轉向(xiàng)可能受到密(mì)封或泵内其(qí)它結構的限(xiàn)制，用戶有反(fǎn)轉要求時應(yīng)在訂貨時做(zuo)出說明。　　

●高粘(zhān)度泵優點：

　　轉(zhuǎn)子泵的軸向(xiàng)位置可調，不(bú)需要拆泵。

　　泵(bèng)采用模塊化(huà)設計，可根據(jù)不同的使用(yong)要求更換不(bú)同🌈部件。可選(xuǎn)夾層結構，以(yǐ)方便對泵加(jia)熱或冷卻，可(kě)以選擇是否(fǒu)帶安🈲全閥，可(kě)以選擇不同(tong)的密封形♍式(shì)，詳見密封結(jié)構圖。泵的各(ge)個零件可以(yǐ)選用不同的(de)材質以适應(yīng)具體使用要(yào)求。

　　不同的使(shǐ)用條件，泵的(de)結構形式可(kě)能不同，具體(tǐ)應用請向廠(chǎng)家或本公司(sī)客戶代表咨(zi)詢。需要指出(chu)的是泵的轉(zhuan)速愈高，泵的(de)磨損愈嚴重(zhong)，液體中如含(han)有磨料物質(zhì)，泵的材料應(yīng)選用耐🐕磨材(cái)質，在此種工(gong)況🔆下，泵的壓(ya)力和轉速🐆都(dou)應降低，高溫(wēn)條件下，則應(yīng)增加泵的間(jiān)隙，并采用耐(nai)熱材料 。

　　流動(dòng)穩定：流量與(yu)齒輪轉速成(cheng)正比，與壓力(li)無關

　　流動平(píng)穩：沒有脈動(dong)和壓力波峰(feng)，不會産生管(guǎn)道顫動。

　　多功(gong)能性：僅僅通(tōng)過調整轉子(zǐ)軸的位置，同(tóng)一台泵既可(kě)以出來稀釋(shì)溶液又可以(yǐ)出來瀝青，糖(tang)漿，樹脂，聚合(hé)⛷️物等👅高粘📱度(du)液體。

　　可逆性(xìng)：可以通過改(gai)變齒輪的旋(xuán)轉方向使液(ye)體反向流動(dòng)，兩種方向都(dōu)能充分發揮(hui)泵的性能

　　自(zì)吸性：由泵産(chan)生高真空，允(yǔn)許在最大自(zì)吸高度實現(xiàn)快速自吸，取(qǔ)決于泵送液(yè)體的物理特(te)性（溫度，蒸汽(qi)壓力，粘度等(deng)👄）。

　　建議性：隻有(yǒu)兩個活動部(bu)件：主動輪和(he)動輪，隻有一(yi)個軸封。

　　堅固(gù)的重載結構(gòu)：低轉速。特大(da)球軸承的外(wai)部軸承座可(ke)以✨承受軸向(xiang)和徑向負載(zǎi)。

　　磨損率低：由(you)于主動輪和(he)從動齒輪不(bú)成倍數關系(xì)。這就意味着(zhe)🏒磨損可以被(bei)均勻的分散(san)在每個齒輪(lún)上。因為一個(ge)齒輪上的每(měi)一個齒輪接(jie)觸另一個齒(chǐ)輪上的每一(yi)個齒輪的次(ci)數一樣。

磨損(sǔn)調節系統：轉(zhuan)子邊緣的磨(mó)損可以通過(guò)調整轉🏃子軸(zhóu)的位置來補(bǔ)償。這樣，即使(shi)在有相當大(da)的磨損的情(qíng)況下，也可⭐以(yi)保證泵的穩(wěn)定性。

　　維護簡(jian)單，維護率低(di)：不用移動泵(bèng)，管道或泵驅(qu)動裝㊙️置就可(ke)以進行檢查(cha)和調節。

　　互動(dong)性：标準組件(jian)的設計可實(shi)現不同材料(liào)和特性零🤟部(bu)件🧑🏽‍🤝‍🧑🏻之間的替(tì)換。例如：有多(duō)種軸封系統(tǒng)可供選擇，還(hái)可以安裝帶(dài)夾⭐套的外殼(ké)和軸蓋來代(dài)替标準部件(jiàn)。

　　端口位置可(kě)改變：泵殼可(kě)在軸承箱上(shàng)旋轉以從不(bu)同位🔞置處吸(xi)排液體。

　　預熱(rè)：加熱夾套或(huo)是與外殼鑄(zhù)成一體，或是(shi)安裝在端蓋(gài)♻️上，或是安裝(zhuāng)在填料壓蓋(gài)上。

　　旁路安全(quán)閥：旁路安全(quán)閥安裝在泵(beng)上并且容易(yì)調節，在有些(xie)型号的泵上(shàng)采取雙重安(ān)全閥并帶加(jiā)熱夾套。● 高粘(zhan)度泵開機準(zhun)備

　　在開始運(yùn)轉前，往齒輪(lun)泵的殼體内(nèi)灌滿待輸送(sòng)的液體，便于(yú)安全啟動。若(ruo)環境溫🐪度低(di)于冰點，應預(yu)先向泵内通(tōng)入熱蒸汽，進(jìn)行預熱處理(li)，然後才可啟(qi)動齒輪泵。高(gāo)粘度泵的旋(xuán)轉方向要與(yu)進、出油口相(xiàng)符。齒輪泵若(ruò)是第一次運(yùn)行，或長期閑(xián)置後再使用(yòng)，最好在空載(zǎi)或小負荷🛀情(qing)況下先跑合(hé)一小時左右(yòu)。如果在跑合(hé)階段預😘先覺(jiào)察出異常溫(wen)升、洩漏、振動(dong)和噪聲時，應(ying)停機檢查。高(gāo)粘度齒輪泵(bèng)的支座或法(fǎ)蘭與其驅動(dong)電機應采用(yong)共同的安裝(zhuāng)基礎，基礎、法(fǎ)蘭或支座均(jun)需具有足夠(gòu)的剛度，以減(jiǎn)小齒輪泵運(yun)轉時産生的(de)振動和噪聲(shēng)。電動機與齒(chǐ)輪泵須用彈(dan)性聯軸器連(lián)接，同軸度小(xiao)于0.1毫米，傾斜(xié)角不得大于(yu)1度。安裝聯軸(zhóu)器時不得用(yong)錘敲打，以免(mian)傷害齒輪泵(bèng)的齒輪等零(líng)件。若用帶輪(lún)、鍊輪等驅動(dong)時應設托架(jia)😄支承，以防主(zhu)動齒輪軸承(chéng)受徑向力。緊(jin)固齒輪泵、電(dian)動機的地腳(jiao)螺釘時，螺釘(ding)受力應均勻(yun)，連接可靠。用(yong)手🔆轉㊙️動聯軸(zhou)器時，應感覺(jiào)到齒輪泵能(néng)夠輕松地轉(zhuan)動，沒有卡緊(jin)等異常現象(xiàng)出現，然後才(cai)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(gāo)粘度齒輪泵(beng)的吸油管道(dào)内徑應足夠(gou)大，并避免狹(xia)窄通道或急(jí)劇拐♌彎、減少(shǎo)彎頭，去除不(bu)必要的閥門(men)、附件，盡可能(néng)地降低泵的(de)安裝高度，縮(suō)短吸油管道(dào)的長度，以減(jian)少壓力👣損失(shī)。管接頭等元(yuan)件的密封要(yao)良好，以防止(zhi)空氣侵入❄️，從(cong)而控制氣穴(xué)與氣⭕蝕的發(fa)生。止回閥與(yu)安全閥在齒(chǐ)輪泵的輸出(chu)管路上最好(hǎo)安裝一個止(zhi)回閥。這樣在(zai)檢修泵及輸(shū)出管道時，系(xi)統中的液體(ti)不會發生倒(dǎo)流。齒輪泵帶(dài)負荷停車時(shi)，亦可防止泵(bèng)倒轉而在其(qí)輸出管道内(nèi)産生局🤩部真(zhen)空。應當注意(yì)，出口止回閥(fa)不能裝反或(huò)出現卡♉死現(xian)象。高粘度泵(bèng)的出口管路(lu)上還應當設(shè)置安全閥等(deng)保護裝置，這(zhè)樣💰一旦泵的(de)出口通道發(fa)生堵塞，就可(kě)以打開安全(quán)閥卸壓。安全(quán)閥可以與泵(beng)體或泵蓋鑄(zhu)成一體，也可(kě)以單獨裝配(pèi)。對于需要🥵正(zhèng)反轉的高🐉粘(zhān)度齒輪泵，其(qi)進出口管路(lù)上均需設置(zhì)安全閥。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.
