●高粘(zhān)度泵使用時注意事項matters needing attention when using high viscosity pump

　　進(jìn)、出口(kǒu)管路的管(guǎn)徑必(bì)須和泵(bèng)保持一(yī)緻；the diameters of inlet and outlet piping must be consistent with pump;

　　設計管路時(shí)應盡量減少彎(wān)頭，且彎頭(tóu)角度(dù)不宜(yí)過小(xiǎo)，進口(kǒu)管線(xiàn)不宜(yí)過長，以(yǐ)免影響自吸(xī)。

　　啟動前(qián)每個注(zhù)油杯(bēi)都應家潤(rùn)滑油(yóu)，且保證每(měi)天加(jiā)油一次。

　　泵(bèng)在工作前應該(gāi)點動啟動電機(jī)，觀察轉向(xiàng)是否(fǒu)和規定(dìng)轉向一緻。

　　開機後(hòu)觀察(chá)運轉是否(fǒu)正常(cháng)，如有不正常噪音、特殊振(zhèn)動或溫升過高等情(qíng)況，應停機檢查(chá)。

　　注意皮帶(dài)松緊(jǐn)是否恰當，每(měi)半(bàn)年調(diào)整一次。　

●高(gāo)粘度泵工(gōng)作原(yuán)理：

　　高(gāo)粘度(dù)泵是(shì)容(róng)積式内齧合(hé)齒輪泵，主動(dòng)齒(chǐ)輪（外轉子(zǐ)）帶動被動齒(chǐ)輪(lún)（内轉子）旋(xuán)轉時(shí)，不斷産生封(fēng)閉(bì)的空(kōng)間，在吸油區齒輪逐(zhú)漸脫離齧(niè)合而液(yè)體不斷(duàn)地充(chōng)滿齒間并(bìng)被帶(dài)到出油區(qū)，齒輪在出油區(qū)進入(rù)齧合時液(yè)體被排出(chū)。兩個旋轉(zhuǎn)齒輪(lún)的共同作用，形成一(yī)個穩(wěn)定的體積排量，沒有(yǒu)脈動(dòng)。由于(yú)泵是(shì)完全(quán)對稱(chēng)的，泵(bèng)可以(yǐ)反(fǎn)轉，液流方向(xiàng)也随之改變。但(dàn)應注意，泵(bèng)的轉向可能受到密封或(huò)泵(bèng)内其它(tā)結構的限制，用(yòng)戶有反(fǎn)轉要求(qiú)時應(yīng)在(zài)訂貨時做出說明(míng)。　　

●高粘(zhān)度泵優點(diǎn)：

　　轉子泵的軸向(xiàng)位置(zhì)可調，不需(xū)要拆泵。

　　泵(bèng)采用模塊(kuài)化設計，可根據(jù)不同(tóng)的(de)使用要(yào)求更換(huàn)不(bú)同部(bù)件。可選夾層結(jié)構，以方便(biàn)對泵(bèng)加熱或(huò)冷卻，可以選(xuǎn)擇是(shì)否帶(dài)安全(quán)閥，可以選(xuǎn)擇不(bú)同的(de)密(mì)封(fēng)形式，詳見密封(fēng)結構(gòu)圖(tú)。泵(bèng)的各(gè)個零(líng)件(jiàn)可(kě)以選用不(bú)同(tóng)的材質(zhì)以适應具(jù)體使(shǐ)用要求。

　　不(bú)同的(de)使用條(tiáo)件，泵的(de)結構形式可能(néng)不同，具體應用(yòng)請向廠(chǎng)家或本(běn)公司客(kè)戶代表(biǎo)咨詢。需要指出(chū)的是(shì)泵的(de)轉速(sù)愈高，泵的磨損(sǔn)愈嚴重，液體中(zhōng)如含(hán)有磨料物(wù)質，泵(bèng)的材料應(yīng)選用耐磨材質，在此種工(gōng)況下(xià)，泵的壓(yā)力和轉速都(dōu)應降低，高(gāo)溫條件下，則應增加泵的(de)間隙(xì)，并(bìng)采用耐熱材(cái)料 。

　　流動穩定：流(liú)量與齒輪轉速(sù)成正比，與壓力(lì)無關

　　流動平穩(wěn)：沒有(yǒu)脈動和壓(yā)力波峰(fēng)，不(bú)會産生管(guǎn)道顫(chàn)動。

　　多(duō)功能(néng)性(xìng)：僅僅通過調整轉子軸(zhóu)的位置，同(tóng)一台(tái)泵既可以出來稀釋溶液又可(kě)以出來(lái)瀝青，糖漿，樹脂，聚(jù)合物(wù)等(děng)高(gāo)粘度液體(tǐ)。

　　可逆(nì)性：可以(yǐ)通過改變(biàn)齒輪的(de)旋轉方向使液(yè)體反向流動，兩(liǎng)種方向都能充(chōng)分發揮泵的性(xìng)能

　　自吸性(xìng)：由泵(bèng)産生(shēng)高(gāo)真空，允許在(zài)最大(dà)自吸(xī)高度(dù)實現快速(sù)自吸(xī)，取決于泵送液體的物理(lǐ)特性（溫度，蒸汽(qì)壓力(lì)，粘度等）。

　　建(jiàn)議性(xìng)：隻有兩個(gè)活動(dòng)部件：主(zhǔ)動輪和動輪，隻有一個軸(zhóu)封。

　　堅固的重載(zǎi)結(jié)構：低(dī)轉速(sù)。特(tè)大(dà)球軸(zhóu)承的外部(bù)軸承座可以承(chéng)受軸(zhóu)向和徑(jìng)向負載(zǎi)。

　　磨損率低：由于主動輪和從動齒輪(lún)不(bú)成倍(bèi)數(shù)關系。這就意味(wèi)着磨(mó)損(sǔn)可(kě)以被(bèi)均勻的分散在(zài)每個齒輪(lún)上。因(yīn)為一個齒(chǐ)輪上的每一個齒輪接觸另一個齒(chǐ)輪上(shàng)的每一個(gè)齒輪的次數一(yī)樣。

磨(mó)損調節系(xì)統：轉子邊(biān)緣的磨損(sǔn)可以通過(guò)調整(zhěng)轉子軸的位置(zhì)來補償。這(zhè)樣，即(jí)使在(zài)有相(xiàng)當大(dà)的磨損的(de)情況下，也可以保證(zhèng)泵的穩定(dìng)性。

　　維護簡單，維護率(lǜ)低：不用移動泵(bèng)，管(guǎn)道(dào)或泵(bèng)驅動裝置就可(kě)以進行檢(jiǎn)查和(hé)調節。

　　互(hù)動性：标(biāo)準組件的設(shè)計可實(shí)現不(bú)同材(cái)料和特性(xìng)零部(bù)件之間的替換。例如：有多種軸(zhóu)封系統可供(gòng)選(xuǎn)擇，還(hái)可以安裝(zhuāng)帶夾套的外殼和軸蓋來代替(tì)标準部件。

　　端口(kǒu)位置可改變：泵殼可(kě)在軸承箱上旋轉以從不(bú)同位(wèi)置處吸排液體(tǐ)。

　　預熱：加熱(rè)夾套或是與外殼鑄(zhù)成一(yī)體，或(huò)是安裝在端蓋(gài)上，或是安(ān)裝在填料壓蓋(gài)上。

　　旁(páng)路安全閥：旁路(lù)安全閥安(ān)裝在(zài)泵上并且(qiě)容易(yì)調節，在有些型(xíng)号(hào)的(de)泵(bèng)上(shàng)采取雙重安(ān)全閥并(bìng)帶加熱夾(jiá)套。

●nyp高(gāo)粘度泵的進出口

　　泵(bèng)進出口的(de)型式

　　常規泵進(jìn)出口尺(chǐ)寸(cùn)相同(tóng)，進出口呈垂直(zhí)布置，從驅動機(jī)向泵頭方(fāng)向看(kàn)為右進上出。也(yě)可根(gēn)據客(kè)戶(hù)需(xū)要，加工成(chéng)水平進出口型或左(zuǒ)進上(shàng)出型。連接方式有法蘭型(xíng)和螺(luó)紋(wén)型.

　　泵進(jìn)出口(kǒu)負荷

　　泵在(zài)安裝(zhuāng)時，應限制(zhì)泵的進(jìn)出口所(suǒ)承受的管路負(fù)荷。螺(luó)紋聯接的(de)管接(jiē)頭不得承(chéng)受負(fù)荷，否則會(huì)使泵的聯(lián)接管(guǎn)産(chǎn)生(shēng)松動或旋(xuán)緊力矩（管螺紋(wén)聯接(jiē)處不(bú)允許(xǔ)有旋緊或松動(dòng)的扭(niǔ)矩，以(yǐ)免）影(yǐng)響管路的(de)聯接(jiē)效果。

●nyp高粘度泵(bèng)的起動

　　泵(bèng)在起(qǐ)動過(guò)程(chéng)中應特别注(zhù)意以下幾個問(wèn)題：

　　起動前(qián)要檢(jiǎn)查下列内(nèi)容：

　　檢查泵、齒輪(lún)箱和電機的對中程(chéng)度；

　　檢查過(guò)濾器中有(yǒu)沒有(yǒu)焊皮和金(jīn)屬渣(zhā)；

　　檢查(chá)各(gè)連接部位連接(jiē)是否緊(jǐn)固；

　　檢查管(guǎn)路壓(yā)在泵上的力和(hé)力矩是否(fǒu)超過(guò)給定的數值，如(rú)果溫度較高，還(hái)應檢查管路是(shì)否有膨脹節；

　　檢(jiǎn)查電(diàn)氣連接的正确性及電機(jī)的額定值，并檢查電機轉(zhuǎn)動方向是否正确；

　　檢(jiǎn)查泵(bèng)的轉(zhuǎn)動方向是否正确；

　　如(rú)有安全(quán)閥，安全閥安(ān)裝必須正(zhèng)确，

　　檢查(chá)泵(bèng)軸是否轉動靈活；

　　泵(bèng)的内(nèi)部不(bú)能是(shì)幹的(de)，特别是需(xū)要自(zì)吸的時候(hòu)，應向泵(bèng)内灌注(zhù)一些(xiē)油或輸送(sòng)的液(yè)體；

　　泵組裝(zhuāng)時在零件(jiàn)的表(biǎo)面有(yǒu)防護液，如(rú)果這種(zhǒng)液體不(bú)能和(hé)泵(bèng)送液體(tǐ)相容，則必(bì)須清(qīng)洗；

　　最(zuì)好在管路(lù)上安裝壓(yā)力表和真空表，方便(biàn)觀察泵(bèng)的(de)工作(zuò)狀态；

　　檢(jiǎn)查機械(xiè)密封箱(xiāng)是否注(zhù)滿液(yè)體；

　　檢查管(guǎn)路的(de)閥(fá)門是否(fǒu)打開；

　　如(rú)果用内(nèi)燃機驅動(dòng)，請在(zài)起動(dòng)發動機前(qián)保持離合器脫開；

　　泵(bèng)起動後，檢(jiǎn)查液體是(shì)否進入到(dào)泵中(zhōng)，泵是(shì)否工作正(zhèng)常，如(rú)果長(zhǎng)時間無液(yè)體進入(rù)泵中，應(yīng)停機(jī)檢查泵及(jí)管路。

●高粘(zhān)度齒(chǐ)輪泵并(bìng)不能産(chǎn)生壓力，它(tā)隻是輸(shū)出流(liú)量。壓力(lì)低或無壓(yā)力，說(shuō)明高粘度(dù)齒 輪(lún)泵沒有吸入液(yè)體或(huò)洩(xiè)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(dòng)機輸(shū)出功(gōng)率偏小、齒(chǐ) 輪(lún)泵(bèng)排量選得(dé)過大(dà)或壓(yā)力(lì)調(diào)得過(guò)高時(shí)，也會造成壓力(lì)不足(zú) 當然(rán)，壓力表損壞或(huò)壓力表節流孔(kǒng)堵塞時(shí)也顯示不出壓(yā)力，此時可換裝一個新(xīn)的壓力表檢(jiǎn)查(chá)。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(néng)是由于泵(bèng)安裝(zhuāng)有誤、泵的轉向(xiàng)不對，或(huò)吸(xī)人側(cè)(進液(yè)口及(jí)吸液(yè)管道)堵(dǔ)塞(sāi)、出口(kǒu)止回(huí)閥裝反或卡死了(le)，也有可(kě)能是驅動軸斷裂了。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.

　　高粘度泵(bèng)在轉速過低時(shí)會引起(qǐ)出液量不足，這種現象(xiàng)往往是由(yóu)于泵的驅動裝(zhuāng)置打(dǎ)滑或功率(lǜ)不足(zú)所緻(zhì)。此(cǐ)時應檢(jiǎn)查齒 輪泵的實際轉(zhuǎn)速、泵與電(diàn)動機的聯(lián)接及(jí)功率(lǜ)匹(pǐ)配情況(kuàng)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(zhǔn)備

　　在開始(shǐ)運轉前，往(wǎng)齒(chǐ)輪(lún)泵的(de)殼體内灌(guàn)滿待輸(shū)送的液(yè)體，便(biàn)于安全啟(qǐ)動。若環(huán)境溫度(dù)低于冰點，應(yīng)預(yù)先向(xiàng)泵内通入(rù)熱蒸汽，進行預(yù)熱處(chù)理(lǐ)，然後才(cái)可啟動齒輪泵(bèng)。高粘度(dù)泵(bèng)的旋(xuán)轉方向要與進(jìn)、出油口相(xiàng)符。齒輪泵若是(shì)第一(yī)次運行(háng)，或(huò)長期(qī)閑置後再使(shǐ)用(yòng)，最好在空(kōng)載或小負(fù)荷(hé)情況下(xià)先跑合一(yī)小時(shí)左右。如(rú)果在跑(pǎo)合階段預先(xiān)覺(jiào)察出(chū)異常溫升(shēng)、洩漏、振(zhèn)動(dòng)和噪(zào)聲時，應(yīng)停機檢(jiǎn)查。高(gāo)粘度齒輪(lún)泵的(de)支座或(huò)法(fǎ)蘭與其驅(qū)動電機應采用共同(tóng)的安裝基(jī)礎，基(jī)礎(chǔ)、法蘭(lán)或支座(zuò)均需具有(yǒu)足(zú)夠的剛度，以減小(xiǎo)齒輪(lún)泵運轉時(shí)産生的振動和噪聲(shēng)。電動機與(yǔ)齒輪(lún)泵須用彈(dàn)性聯軸器連接，同軸度小于0.1毫(háo)米，傾(qīng)斜角(jiǎo)不得(dé)大于1度(dù)。安裝聯(lián)軸器時不得用(yòng)錘敲打，以(yǐ)免傷(shāng)害齒輪泵的齒(chǐ)輪等(děng)零件。若用(yòng)帶輪、鍊(liàn)輪等驅(qū)動時(shí)應設托架(jià)支承(chéng)，以防主動齒輪(lún)軸承受徑向力。緊固(gù)齒輪泵、電(diàn)動(dòng)機的地(dì)腳螺釘時(shí)，螺釘(dìng)受力應均(jun1)勻，連(lián)接可靠(kào)。用手轉動聯(lián)軸器時，應(yīng)感(gǎn)覺到齒(chǐ)輪泵(bèng)能夠(gòu)輕松地轉動，沒有卡緊等異常(cháng)現(xiàn)象出現(xiàn)，然後才(cái)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.

     高粘度齒輪(lún)泵的吸油管(guǎn)道(dào)内徑(jìng)應(yīng)足夠大(dà)，并避免狹(xiá)窄通(tōng)道或(huò)急(jí)劇拐彎(wān)、減少彎(wān)頭(tóu)，去除(chú)不必(bì)要的閥門(mén)、附件，盡可(kě)能地降低泵的安裝(zhuāng)高度，縮短吸油管道的長度，以(yǐ)減少壓力(lì)損失(shī)。管接頭(tóu)等元件(jiàn)的密封(fēng)要(yào)良好，以防止空氣侵入，從而控(kòng)制氣(qì)穴與氣(qì)蝕的發(fā)生。止回閥(fá)與安(ān)全閥在(zài)齒輪泵(bèng)的輸(shū)出管路上最好(hǎo)安(ān)裝(zhuāng)一個(gè)止回閥(fá)。這(zhè)樣在檢修(xiū)泵及輸出管道(dào)時，系統中的液(yè)體不會發(fā)生倒流。齒輪泵(bèng)帶負荷停車時，亦可防止(zhǐ)泵倒轉而(ér)在其(qí)輸出(chū)管道内産(chǎn)生局(jú)部(bù)真空。應當注(zhù)意，出口止(zhǐ)回閥(fá)不能裝反(fǎn)或出(chū)現卡(kǎ)死(sǐ)現象。高粘度泵的出口(kǒu)管路上還應當(dāng)設置安全閥(fá)等保護裝置(zhì)，這樣一旦泵(bèng)的出口(kǒu)通道發生堵塞，就可(kě)以(yǐ)打開安(ān)全閥卸壓。安全(quán)閥可以與泵體(tǐ)或泵蓋(gài)鑄(zhù)成一體，也可以單獨(dú)裝配。對于需要(yào)正反(fǎn)轉的(de)高(gāo)粘(zhān)度齒輪泵(bèng)，其進出口管(guǎn)路(lù)上均(jun1)需設置(zhì)安全閥(fá)。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.

   高粘度泵是輸(shū)送高(gāo)粘度(dù)液體的齒(chǐ)輪(lún)泵，應做(zuò)到在較(jiào)低(dī)的功(gōng)耗、較(jiào)少的(de)洩漏(lòu)、較大的壓力下(xià)輸出(chū)最多的流量。在确定(dìng)所要(yào)輸送的介質時，應該嚴格(gé)遵循(xún)産品說明書上(shàng)的規定，盡量使(shǐ)用廠家(jiā)推(tuī)薦的(de)流體介(jiè)質，并注意考(kǎo)慮系統的(de)工(gōng)作溫度範圍(wéi)。當希(xī)望在(zài)某一(yī)較寬的(de)溫度範圍内使(shǐ)用時，輸(shū)送介(jiè)質的粘度(dù)指數應該高些(xiē)。輸送介質不僅是能量傳(chuán)遞的中介，而(ér)且也是(shì)潤滑(huá)、密封及傳(chuán)熱介質。液體粘(zhān)度過(guò)高會增加内摩擦阻(zǔ)力，降低輸(shū)出(chū)功(gōng)率，浪(làng)費能(néng)量(liàng)，并産生過高的系統溫(wēn)度.高粘度(dù)齒輪(lún)泵的(de)出口管路(lù)上應當設(shè)置安(ān)全閥(fá)等(děng)保護裝(zhuāng)置，這樣一旦泵(bèng)的出(chū)口通道發(fā)生堵(dǔ)塞，就可以(yǐ)打開安(ān)全閥卸(xiè)壓。對(duì)于(yú)需要正(zhèng)反轉(zhuǎn)的高粘度(dù)齒輪(lún)泵，其進(jìn)出(chū)口管路上均需(xū)設置安(ān)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.

　　高(gāo)粘度(dù)泵額定的壓力是指(zhǐ)泵連(lián)續工作時的最(zuì)高許用壓力，而其工作壓力則(zé)決定于外部負(fù)載，安裝(zhuāng)和調試(shì)的壽命(mìng)與其工作壓(yā)力直(zhí)接相(xiàng)關。對于不頻繁(fán)工作的齒輪泵(bèng)，其工作壓力可(kě)取為泵的額定壓力(lì)，考慮到産品質(zhì)量不(bú)同，最(zuì)好将(jiāng)額(é)定(dìng)壓(yā)力降低20%～30%使用(yòng)。對于經常工作(zuò)于較(jiào)高壓(yā)力(lì)下的齒(chǐ)輪泵，其工(gōng)作壓力應比泵的額(é)定壓力低(dī)1～2個壓力級。石油化工(gōng)設備(bèi)常常是24小(xiǎo)時連續運轉，這(zhè)時泵的工(gōng)作壓(yā)力應該取(qǔ)得比(bǐ)額定壓力(lì)低得多，且工作轉速也應該低(dī)于額定轉(zhuǎn)速。如果高(gāo)粘度(dù)齒輪泵的(de)工作壓(yā)力調整(zhěng)過高(gāo)，則(zé)會使齒(chǐ)輪(lún)泵在超(chāo)負荷(hé)下運(yùn)行。high viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.for not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.for often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.petrochemical equipment are often 24 hours of continuous operation, and at this time of the pump working pressure should be obtained was much lower than the rated pressure, and the work speed should be lower than the rated speed.if the high viscosity gear pump high pressure adjustment, will make the pump running under overload.

●nyp高粘度泵的安裝(zhuāng)與試(shì)運轉

　　installation and commissioning

　　高粘(zhān)度泵(bèng)的支(zhī)座或法蘭(lán)與(yǔ)其驅動電機(jī)應采用共(gòng)同(tóng)的(de)安裝(zhuāng)基礎(chǔ)，基礎、法蘭或(huò)支座均(jun1)需具有足夠的(de)剛(gāng)度，以減小齒(chǐ)輪泵運轉時産生的振動(dòng)和噪聲。電(diàn)動機(jī)與齒輪泵須用彈性(xìng)聯(lián)軸(zhóu)器連接，同(tóng)軸度(dù)小于0.1毫米(mǐ)，傾斜角(jiǎo)不(bú)得大(dà)于1度(dù)。安裝聯軸(zhóu)器時不得用錘(chuí)敲(qiāo)打，以免傷害(hài)齒輪泵的齒輪(lún)等零件。若(ruò)用帶輪、鍊輪(lún)等驅動時應(yīng)設托架支(zhī)承(chéng)，以防主(zhǔ)動齒(chǐ)輪軸承受徑向(xiàng)力。緊(jǐn)固齒(chǐ)輪泵、電動(dòng)機的地腳(jiǎo)螺釘(dìng)時(shí)，螺(luó)釘受(shòu)力應(yīng)均(jun1)勻，連接(jiē)可靠。用(yòng)手(shǒu)轉(zhuǎn)動聯軸(zhóu)器時(shí)，應感(gǎn)覺到齒輪泵能(néng)夠輕松(sōng)地(dì)轉動(dòng)，沒有(yǒu)卡緊等異(yì)常現象(xiàng)出現，然(rán)後才可以(yǐ)配管。高粘度齒(chǐ)輪泵的吸油管道内徑(jìng)應(yīng)足夠大，并(bìng)避免狹窄通道或急(jí)劇(jù)拐(guǎi)彎、彎頭，去除(chú)不(bú)必要(yào)的閥(fá)門、附件，盡(jìn)可能地(dì)降(jiàng)低泵(bèng)的安裝(zhuāng)高度，縮(suō)短吸油管(guǎn)道的(de)長度，以減少壓(yā)力損失。管接頭等元件的密封(fēng)要良好，以防止空氣(qì)侵入，從而(ér)控制氣(qì)穴與氣蝕的發生(shēng)。在開(kāi)始(shǐ)運(yùn)轉前，往齒(chǐ)輪泵(bèng)的殼體内(nèi)灌滿(mǎn)待輸(shū)送的液體(tǐ)，便(biàn)于安全(quán)動。若環境(jìng)溫度低于(yú)冰點，應預(yù)先向泵(bèng)内通入(rù)熱蒸汽(qì)，進行預(yù)熱處(chù)理，然(rán)後才(cái)可啟(qǐ)動齒輪泵(bèng)。齒輪泵(bèng)的(de)旋轉(zhuǎn)方向要(yào)與(yǔ)進、出油口(kǒu)相(xiàng)符(fú)。齒輪泵若是(shì)第一次(cì)運行(háng)，或長期閑置(zhì)後再使(shǐ)用，最(zuì)好在空載或小(xiǎo)負荷(hé)情況下先(xiān)跑合一小(xiǎo)時左(zuǒ)右。如(rú)果在跑合(hé)階段預先(xiān)覺出(chū)異常溫升、洩漏(lòu)、振動和噪(zào)聲時(shí)，應機(jī)檢查。高粘(zhān)度泵(bèng)的出(chū)口管(guǎn)路(lù)上還應當設(shè)置安(ān)全閥等保護裝置，這樣一(yī)旦泵(bèng)的出口通(tōng)道發(fā)生堵塞，就可以(yǐ)打開(kāi)安全(quán)閥卸(xiè)壓。對于需(xū)要正反轉的高粘度齒(chǐ)輪泵，其(qí)進出口管路上(shàng)均需設(shè)置安全(quán)閥。high viscosity pump bearing or flange and its drive motor should use common installation basis, 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 gear and other parts of the gear pump.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.high viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp bend, bend, 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.before starting operation, to gear pump casing filled with liquid, easy to safety.if the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.direction of rotation of the gear pump, 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 the abnormal temperature rise, leakage, vibration and noise, should machine inspection.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.for high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.nyp高粘度泵相關業績
