●高(gāo)粘度泵(bèng)工作原(yuán)理：

　　高(gāo)粘度泵是(shì)容(róng)積式内齧合(hé)齒輪(lún)泵，主動齒(chǐ)輪（外轉(zhuǎn)子）帶動(dòng)被動齒(chǐ)輪（内轉子）旋(xuán)轉時，不斷(duàn)産生(shēng)封閉的空(kōng)間，在吸(xī)油(yóu)區齒(chǐ)輪逐漸脫(tuō)離齧(niè)合而(ér)液(yè)體(tǐ)不斷(duàn)地充滿齒間并(bìng)被帶到(dào)出油區(qū)，齒輪在出油(yóu)區(qū)進入齧合時液(yè)體被排出(chū)。兩個(gè)旋轉(zhuǎn)齒輪的共同作用(yòng)，形成一(yī)個穩定的體積(jī)排量，沒有脈動。由于泵是完全對稱(chēng)的，泵可以反轉(zhuǎn)，液流方向(xiàng)也随之改變。但(dàn)應注(zhù)意(yì)，泵(bèng)的轉(zhuǎn)向可能受到密(mì)封或(huò)泵内其它(tā)結構的限(xiàn)制，用戶有(yǒu)反轉要求(qiú)時應在訂貨時做出(chū)說明。　　

●高粘(zhān)度泵優點(diǎn)：

　　轉子(zǐ)泵的軸向位置(zhì)可調，不需(xū)要拆(chāi)泵。

　　泵(bèng)采(cǎi)用(yòng)模塊(kuài)化設計，可根據不同(tóng)的(de)使用要求更換不同部(bù)件。可選夾層結構，以方便(biàn)對泵(bèng)加熱或(huò)冷卻，可(kě)以選擇是(shì)否帶(dài)安全閥，可(kě)以選(xuǎn)擇不(bú)同(tóng)的(de)密封(fēng)形式，詳見密封(fēng)結構(gòu)圖(tú)。泵(bèng)的各個零件可以選(xuǎn)用不同的材質(zhì)以适應具體使(shǐ)用要求(qiú)。

　　不同的(de)使用(yòng)條件，泵的(de)結構(gòu)形式可能不同，具體應用(yòng)請向(xiàng)廠家或(huò)本(běn)公司客戶(hù)代表(biǎo)咨詢(xún)。需(xū)要指出(chū)的是(shì)泵(bèng)的轉速愈高，泵的磨損(sǔn)愈嚴重(zhòng)，液體中(zhōng)如含有磨(mó)料物(wù)質，泵的材料應選用(yòng)耐磨(mó)材質，在此種(zhǒng)工況下(xià)，泵的壓力(lì)和轉(zhuǎn)速都應降低，高溫條件(jiàn)下，則應增加(jiā)泵的間隙，并采用耐(nài)熱材(cái)料 。

　　流(liú)動穩定：流量與齒輪(lún)轉速(sù)成正比，與(yǔ)壓力(lì)無關

　　流動平穩(wěn)：沒有(yǒu)脈動(dòng)和壓(yā)力波峰(fēng)，不會産(chǎn)生管(guǎn)道顫動。

　　多(duō)功能性：僅(jǐn)僅通(tōng)過調(diào)整轉子軸(zhóu)的位置，同(tóng)一台(tái)泵既可以出來(lái)稀釋(shì)溶液(yè)又可(kě)以出來瀝青，糖(táng)漿，樹(shù)脂，聚合物等(děng)高(gāo)粘度液體(tǐ)。

　　可逆(nì)性(xìng)：可以通過改(gǎi)變齒(chǐ)輪的旋轉方向使液(yè)體反向流(liú)動，兩(liǎng)種(zhǒng)方向(xiàng)都能充(chōng)分發揮泵(bèng)的(de)性(xìng)能

　　自吸性：由泵(bèng)産生高真空，允許在最大自吸(xī)高度(dù)實現快速(sù)自吸，取決(jué)于泵(bèng)送液(yè)體的(de)物理(lǐ)特性（溫度，蒸汽壓力，粘度等）。

　　建議性：隻有(yǒu)兩個(gè)活動部件：主動(dòng)輪和動輪，隻有(yǒu)一個軸封(fēng)。

　　堅固(gù)的重載(zǎi)結(jié)構：低轉速。特(tè)大球軸(zhóu)承的(de)外部(bù)軸承(chéng)座可(kě)以承(chéng)受軸(zhóu)向和徑向(xiàng)負載(zǎi)。

　　磨損(sǔn)率低：由于主動輪和從動(dòng)齒輪不成倍(bèi)數(shù)關系。這就意味(wèi)着磨(mó)損(sǔn)可以被(bèi)均勻的分散在(zài)每個齒輪上。因(yīn)為一個齒(chǐ)輪上(shàng)的每一(yī)個齒輪(lún)接觸另一個齒輪上(shàng)的每(měi)一個(gè)齒輪(lún)的(de)次(cì)數一(yī)樣。

磨損調(diào)節系(xì)統：轉子(zǐ)邊緣的(de)磨損可以通過(guò)調整轉子軸的位(wèi)置來補償。這(zhè)樣，即使在(zài)有(yǒu)相(xiàng)當大的磨(mó)損的(de)情況下，也可以保證泵的穩定(dìng)性。

　　維護簡單，維護率(lǜ)低：不用移(yí)動泵，管道或泵驅動(dòng)裝置就可(kě)以進(jìn)行檢查和(hé)調節。

　　互動(dòng)性：标(biāo)準組件的(de)設計可實現(xiàn)不同材(cái)料和特(tè)性零部(bù)件之間的替換(huàn)。例(lì)如：有(yǒu)多種軸(zhóu)封系統(tǒng)可(kě)供選(xuǎn)擇，還可以(yǐ)安裝帶夾(jiá)套(tào)的外殼(ké)和軸(zhóu)蓋來(lái)代替标準部(bù)件。

　　端口(kǒu)位置可改變(biàn)：泵(bèng)殼可(kě)在軸承箱(xiāng)上旋(xuán)轉以從不同位置處吸排液體。

　　預熱：加熱夾套(tào)或是(shì)與外(wài)殼鑄(zhù)成一體，或(huò)是安裝在端蓋(gài)上，或是安(ān)裝在填料壓蓋上。

　　旁(páng)路安全閥：旁(páng)路安全閥安裝在(zài)泵上并(bìng)且容易(yì)調節，在有些型(xíng)号的泵上采取(qǔ)雙重安全閥并(bìng)帶加熱(rè)夾套。

●nyp高粘度泵的進出(chū)口

　　泵(bèng)進(jìn)出口的型式(shì)

　　常規泵進(jìn)出口尺(chǐ)寸相同(tóng)，進出(chū)口呈垂直(zhí)布置，從驅(qū)動機向泵頭(tóu)方向看(kàn)為右進上出。也(yě)可根(gēn)據(jù)客戶需(xū)要，加(jiā)工成(chéng)水平(píng)進出口型或左(zuǒ)進上(shàng)出型(xíng)。連接(jiē)方式有法蘭型(xíng)和螺紋型.

　　泵(bèng)進出口(kǒu)負荷(hé)

　　泵在(zài)安裝時(shí)，應限制泵的進出口所(suǒ)承受(shòu)的(de)管(guǎn)路負荷。螺(luó)紋聯接(jiē)的(de)管接頭不(bú)得承(chéng)受負(fù)荷，否則會(huì)使泵的聯接管産生松動或旋(xuán)緊力矩（管螺紋(wén)聯接處不(bú)允許有旋緊或(huò)松動的扭矩，以(yǐ)免）影(yǐng)響(xiǎng)管(guǎn)路的(de)聯接(jiē)效果。

●nyp高粘度泵(bèng)的起(qǐ)動(dòng)

　　泵在起(qǐ)動過程中應特(tè)别注意以(yǐ)下幾(jǐ)個問題：

　　起動前(qián)要檢查下列内容：

　　檢查泵(bèng)、齒輪(lún)箱和電機(jī)的對(duì)中程度(dù)；

　　檢查過(guò)濾(lǜ)器中有沒有(yǒu)焊皮(pí)和金屬渣(zhā)；

　　檢查(chá)各(gè)連(lián)接部(bù)位連(lián)接(jiē)是(shì)否緊固；

　　檢查管路壓在泵(bèng)上(shàng)的力和(hé)力矩是否超過(guò)給定(dìng)的數值，如(rú)果溫度(dù)較(jiào)高，還(hái)應檢查管(guǎn)路是否有(yǒu)膨(péng)脹節；

　　檢查電(diàn)氣連接的正确(què)性(xìng)及電機(jī)的額(é)定值，并檢查電機轉(zhuǎn)動方(fāng)向是(shì)否正(zhèng)确；

　　檢(jiǎn)查泵的轉(zhuǎn)動方(fāng)向是(shì)否正确；

　　如有安全閥，安全(quán)閥安(ān)裝必須正确(què)，

　　檢查(chá)泵軸是否轉動靈活(huó)；

　　泵(bèng)的内部不能是幹的，特(tè)别是需(xū)要自吸的(de)時候(hòu)，應向(xiàng)泵内灌注(zhù)一些油(yóu)或(huò)輸送(sòng)的液(yè)體；

　　泵組裝(zhuāng)時在零件的表(biǎo)面有防護(hù)液，如果這種液體不(bú)能和泵送液體(tǐ)相容，則必須清洗；

　　最(zuì)好(hǎo)在管路上安裝壓力表(biǎo)和真(zhēn)空表，方便(biàn)觀察泵的(de)工(gōng)作狀态(tài)；

　　檢查(chá)機械(xiè)密封箱是(shì)否注(zhù)滿液(yè)體；

　　檢查管(guǎn)路的閥門是否(fǒu)打開(kāi)；

　　如(rú)果用内(nèi)燃機(jī)驅動，請在(zài)起動(dòng)發動機前保持(chí)離合器脫開；

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

●高粘(zhān)度齒輪泵并不能産生壓力，它隻是(shì)輸出流量。壓力(lì)低或無壓力，說明高粘度(dù)齒 輪泵沒有吸(xī)入液(yè)體或(huò)洩漏(lòu)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.

　　電動機輸出功(gōng)率偏(piān)小、齒 輪泵排量選得(dé)過大或壓力(lì)調得過(guò)高時，也(yě)會(huì)造成壓(yā)力不足 當然(rán)，壓力(lì)表損壞或(huò)壓力(lì)表(biǎo)節(jiē)流孔(kǒng)堵塞時也(yě)顯示(shì)不出(chū)壓力，此時可換裝一個新的壓力表(biǎo)檢查(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(guǒ)确認(rèn)泵無(wú)流量輸出，可能(néng)是由于(yú)泵安裝有(yǒu)誤、泵的轉向(xiàng)不對，或吸人(rén)側(進液(yè)口及(jí)吸液(yè)管道)堵(dǔ)塞(sāi)、出口(kǒu)止回閥裝反或(huò)卡死了，也(yě)有可能是驅動軸斷(duàn)裂了(le)。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(bèng)在轉(zhuǎn)速(sù)過(guò)低時(shí)會引起出液量不足，這種現象(xiàng)往往(wǎng)是由(yóu)于泵(bèng)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(bèng)的實際轉(zhuǎn)速、泵與(yǔ)電動機的(de)聯(lián)接及功率匹(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(zhān)度泵開(kāi)機準備

　　在開始(shǐ)運轉前，往齒輪(lún)泵的殼體内灌滿待輸送的液(yè)體，便(biàn)于(yú)安(ān)全啟(qǐ)動。若環(huán)境(jìng)溫度(dù)低于冰點(diǎn)，應預(yù)先向泵内(nèi)通入(rù)熱蒸汽，進行預(yù)熱處理，然後才(cái)可啟(qǐ)動齒輪泵(bèng)。高粘度泵的(de)旋(xuán)轉方向(xiàng)要與進、出油口相符。齒(chǐ)輪泵(bèng)若(ruò)是第一次(cì)運(yùn)行，或長期(qī)閑置(zhì)後再使用(yòng)，最好(hǎo)在空(kōng)載或(huò)小負(fù)荷情況下先跑合一小時(shí)左右(yòu)。如果在跑(pǎo)合階段(duàn)預(yù)先覺察出異常溫升(shēng)、洩漏、振(zhèn)動和噪(zào)聲時(shí)，應停機檢(jiǎn)查。高(gāo)粘度(dù)齒輪(lún)泵的支座或法(fǎ)蘭與其(qí)驅(qū)動電機應(yīng)采用共同(tóng)的安(ān)裝基(jī)礎，基(jī)礎、法蘭或(huò)支座(zuò)均需具有足夠(gòu)的剛(gāng)度，以減小(xiǎo)齒輪泵運轉時産生的振(zhèn)動和(hé)噪聲。電動機與齒輪(lún)泵須用(yòng)彈(dàn)性聯軸(zhóu)器(qì)連接(jiē)，同軸(zhóu)度小于0.1毫(háo)米，傾(qīng)斜角不得(dé)大(dà)于1度。安裝聯(lián)軸器時不(bú)得用錘敲(qiāo)打，以(yǐ)免傷(shāng)害齒(chǐ)輪泵的齒(chǐ)輪等零件。若用帶輪、鍊輪(lún)等驅動時應設托架支承，以(yǐ)防主動(dòng)齒輪軸承受徑(jìng)向力(lì)。緊固齒輪(lún)泵(bèng)、電動機的地(dì)腳螺釘時，螺釘受力(lì)應均(jun1)勻，連接可靠。用(yòng)手轉動聯(lián)軸器時，應(yīng)感覺(jiào)到齒(chǐ)輪泵(bèng)能夠輕松(sōng)地轉(zhuǎn)動，沒有卡(kǎ)緊等異常現(xiàn)象出現(xiàn)，然後才可(kě)以配(pèi)管(guǎn)。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(zhān)度齒輪(lún)泵的吸油管道(dào)内徑應足夠大(dà)，并避免狹(xiá)窄通(tōng)道或急劇拐彎(wān)、減(jiǎn)少彎頭，去除(chú)不必要的閥門(mén)、附件，盡可(kě)能地(dì)降低(dī)泵(bèng)的安裝(zhuāng)高度(dù)，縮(suō)短吸油(yóu)管道的長度，以(yǐ)減少壓力損(sǔn)失(shī)。管接頭等元件(jiàn)的密封(fēng)要良好(hǎo)，以防(fáng)止(zhǐ)空(kōng)氣侵(qīn)入，從而控制氣(qì)穴與氣蝕的發(fā)生。止回閥(fá)與安全閥在(zài)齒(chǐ)輪泵(bèng)的輸出管路上(shàng)最(zuì)好安裝一個(gè)止回(huí)閥。這樣在(zài)檢修泵及輸出(chū)管道時，系統中的液(yè)體(tǐ)不會發(fā)生(shēng)倒流。齒輪泵帶負荷停(tíng)車時(shí)，亦可(kě)防止泵倒轉而在其輸出(chū)管道内産生局(jú)部真空。應當注(zhù)意，出口止回閥不能(néng)裝反或出(chū)現卡死現象。高粘度泵的出口(kǒu)管路上還(hái)應當(dāng)設置安全閥等(děng)保護(hù)裝置(zhì)，這樣(yàng)一旦(dàn)泵(bèng)的(de)出口(kǒu)通道發(fā)生堵塞(sāi)，就可以打(dǎ)開安(ān)全閥卸壓。安全(quán)閥可以(yǐ)與泵體(tǐ)或泵蓋(gài)鑄(zhù)成一體，也(yě)可以單獨裝(zhuāng)配。對于(yú)需要(yào)正反(fǎn)轉的(de)高粘(zhān)度齒輪泵(bèng)，其進出口管路上均(jun1)需設置安全閥。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.

   高粘度泵是輸(shū)送高粘度液體(tǐ)的齒輪泵(bèng)，應做(zuò)到在較(jiào)低(dī)的功耗、較少的(de)洩漏(lòu)、較(jiào)大的壓(yā)力下輸出(chū)最(zuì)多的流(liú)量。在确定(dìng)所要(yào)輸送的介(jiè)質時(shí)，應該嚴格(gé)遵循(xún)産品(pǐn)說明(míng)書上(shàng)的規定(dìng)，盡量使(shǐ)用廠(chǎng)家推薦的(de)流體介質，并注(zhù)意考(kǎo)慮系統的(de)工作溫度範圍(wéi)。當希望在某一(yī)較寬的溫度範圍内(nèi)使用時，輸(shū)送介(jiè)質的(de)粘度(dù)指數(shù)應該高些(xiē)。輸送介質不僅(jǐn)是能量(liàng)傳(chuán)遞的中介，而(ér)且也是潤滑(huá)、密封及傳(chuán)熱介質。液體粘(zhān)度過(guò)高會(huì)增加(jiā)内摩擦阻力，降低輸(shū)出(chū)功率，浪(làng)費能量，并産生過高(gāo)的系統溫(wēn)度.高(gāo)粘度齒輪(lún)泵的(de)出(chū)口(kǒu)管路(lù)上應當設置安(ān)全閥(fá)等保護裝(zhuāng)置，這樣(yàng)一(yī)旦泵(bèng)的出口(kǒu)通(tōng)道發(fā)生堵塞，就(jiù)可以(yǐ)打開(kāi)安全閥卸壓。對(duì)于(yú)需要正(zhèng)反轉(zhuǎn)的高粘度(dù)齒輪(lún)泵，其進出(chū)口管路上均需設置(zhì)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)泵連續工作(zuò)時的最高許(xǔ)用壓力，而(ér)其工作(zuò)壓(yā)力則(zé)決定于外部負載，安裝和調試(shì)的壽命(mìng)與其工(gōng)作壓力直接相(xiàng)關。對于不頻繁工作的齒輪泵，其工作(zuò)壓力可取為泵的額定(dìng)壓力(lì)，考慮(lǜ)到産(chǎn)品質(zhì)量不同，最(zuì)好将額(é)定壓力降低20%～30%使用(yòng)。對于(yú)經常工作(zuò)于較高壓(yā)力下的齒(chǐ)輪泵，其(qí)工作壓(yā)力應比泵的額定壓力低1～2個壓(yā)力級。石油化工(gōng)設備(bèi)常(cháng)常(cháng)是24小(xiǎo)時(shí)連續運轉，這(zhè)時泵的工(gōng)作壓力應(yīng)該取(qǔ)得比(bǐ)額定壓(yā)力低得多，且(qiě)工作轉速(sù)也應該低(dī)于額定轉速。如(rú)果高粘度齒輪(lún)泵的(de)工作壓(yā)力調整過高，則會使齒輪泵在超負荷(hé)下運行。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(gāo)粘度(dù)泵的安裝(zhuāng)與試(shì)運轉

　　installation and commissioning

　　高(gāo)粘(zhān)度泵(bèng)的支座(zuò)或法蘭(lán)與其驅動電機(jī)應采(cǎi)用共同的安裝基礎，基礎(chǔ)、法蘭或支(zhī)座均(jun1)需具有足夠的(de)剛度(dù)，以(yǐ)減小齒(chǐ)輪泵(bèng)運轉時(shí)産(chǎn)生的(de)振動和噪聲。電動(dòng)機與齒輪泵須用彈性(xìng)聯軸(zhóu)器連接，同(tóng)軸度(dù)小于0.1毫米(mǐ)，傾斜角不得大于1度。安裝聯軸(zhóu)器時不得(dé)用錘(chuí)敲(qiāo)打(dǎ)，以免傷害(hài)齒輪泵的齒(chǐ)輪(lún)等零件。若(ruò)用帶(dài)輪、鍊輪等(děng)驅動(dòng)時應(yīng)設托架支(zhī)承，以防(fáng)主(zhǔ)動齒(chǐ)輪軸承受徑向(xiàng)力。緊固(gù)齒(chǐ)輪泵(bèng)、電動(dòng)機的地腳(jiǎo)螺釘(dìng)時，螺釘受力(lì)應(yīng)均勻，連接(jiē)可靠(kào)。用手轉動(dòng)聯軸器時，應感(gǎn)覺到齒(chǐ)輪(lún)泵能(néng)夠輕(qīng)松地轉動(dòng)，沒有卡(kǎ)緊(jǐn)等異(yì)常現(xiàn)象出現，然後才可以(yǐ)配管(guǎn)。高粘(zhān)度齒輪泵(bèng)的吸油管(guǎn)道内(nèi)徑應(yīng)足(zú)夠大，并(bìng)避免(miǎn)狹窄通(tōng)道或急(jí)劇拐(guǎi)彎、彎頭，去除不(bú)必要(yào)的閥(fá)門(mén)、附件，盡(jìn)可能(néng)地(dì)降(jiàng)低泵的安裝高度，縮(suō)短吸油管(guǎn)道的(de)長度(dù)，以減少壓(yā)力損失。管接頭(tóu)等元件的密封(fēng)要良好，以(yǐ)防(fáng)止空氣侵入，從而(ér)控制氣穴(xué)與氣蝕的(de)發生(shēng)。在開(kāi)始運轉前，往齒(chǐ)輪泵的殼體内(nèi)灌滿待(dài)輸(shū)送的(de)液體，便于安全(quán)動。若(ruò)環(huán)境溫度低(dī)于(yú)冰點，應預(yù)先向泵内通入(rù)熱蒸(zhēng)汽，進(jìn)行預(yù)熱處理(lǐ)，然後才可啟(qǐ)動齒輪泵(bèng)。齒輪泵的(de)旋轉(zhuǎn)方向要與進(jìn)、出(chū)油口相(xiàng)符。齒輪(lún)泵若是第一次(cì)運行，或長(zhǎng)期閑置(zhì)後再使用，最(zuì)好在(zài)空(kōng)載或小(xiǎo)負荷情(qíng)況(kuàng)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(cháng)溫升、洩(xiè)漏(lòu)、振動和噪(zào)聲時(shí)，應機檢(jiǎn)查。高粘(zhān)度泵的出口管路上還應當設(shè)置安全閥(fá)等保(bǎo)護裝置，這樣一(yī)旦泵的出(chū)口通(tōng)道發(fā)生堵塞，就(jiù)可以(yǐ)打開安全(quán)閥卸壓。對于需(xū)要正(zhèng)反轉的高(gāo)粘度齒輪泵，其(qí)進出口管路上(shàng)均需設置安全(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(dù)泵相關(guān)業績
