●高粘(zhān)度齒(chǐ)輪泵(bèng)适(shì)用(yòng)範圍(wéi):

   ●高粘度齒(chǐ)輪泵(bèng)并不(bú)能産生壓(yā)力，它隻是(shì)輸出(chū)流量(liàng)。壓力(lì)低或(huò)無壓(yā)力，說明高(gāo)粘度齒 輪泵沒(méi)有吸(xī)入液體或洩漏嚴(yán)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(dòng)機輸出(chū)功率偏(piān)小、齒 輪(lún)泵排量(liàng)選得過大(dà)或壓(yā)力調(diào)得過高時(shí)，也會(huì)造成(chéng)壓力(lì)不足(zú) 當然，壓力(lì)表損(sǔn)壞或壓力(lì)表節流孔堵塞(sāi)時也顯(xiǎn)示不出壓力，此時可換(huàn)裝一個新(xīn)的壓(yā)力表(biǎo)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(guǒ)确認泵無(wú)流量輸出，可(kě)能是由(yóu)于泵安裝有誤(wù)、泵的轉向(xiàng)不對(duì)，或吸人側(進液(yè)口及(jí)吸(xī)液管道)堵塞(sāi)、出口止回(huí)閥裝(zhuāng)反(fǎn)或卡死(sǐ)了，也有(yǒu)可(kě)能是(shì)驅動(dòng)軸斷裂了(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.

　　高粘度泵(bèng)在轉速過(guò)低時(shí)會引(yǐn)起出液量(liàng)不足(zú)，這種(zhǒng)現象往(wǎng)往(wǎng)是由(yóu)于泵(bèng)的驅動裝(zhuāng)置打滑或(huò)功率不(bú)足所緻。此時應檢查齒(chǐ) 輪泵的實際轉速、泵與電動機(jī)的聯接(jiē)及(jí)功率匹配(pèi)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(gāo)粘度泵(bèng)在開始(shǐ)運轉前，往齒輪(lún)泵的殼體内灌(guàn)滿待(dài)輸(shū)送的液(yè)體，便于(yú)安(ān)全啟動。若(ruò)環境溫度(dù)低于冰點，應(yīng)預(yù)先向泵内(nèi)通入熱蒸(zhēng)汽(qì)，進行預(yù)熱處(chù)理，然後才(cái)可啟動齒輪泵(bèng)。高粘度泵的旋(xuán)轉方向要與進(jìn)、出油(yóu)口相符。齒(chǐ)輪泵若是第一(yī)次運行，或(huò)長期(qī)閑置後再(zài)使用，在空載或小負(fù)荷情況下先跑(pǎo)合一小時左右(yòu)。如果在跑合階段預先覺察出(chū)異常溫升(shēng)、洩漏(lòu)、振動(dòng)和噪聲時(shí)，應停機(jī)檢(jiǎn)查。高粘度齒(chǐ)輪泵的(de)支座或(huò)法蘭(lán)與(yǔ)其驅動電(diàn)機應(yīng)采用共同(tóng)的安(ān)裝基(jī)礎，基礎、法(fǎ)蘭或(huò)支座均需(xū)具有足夠(gòu)的剛(gāng)度，以減(jiǎn)小(xiǎo)齒輪(lún)泵運轉(zhuǎn)時産生(shēng)的振動和(hé)噪聲。電(diàn)動機與齒輪(lún)泵須用(yòng)彈性聯(lián)軸器連接，同軸(zhóu)度小(xiǎo)于0.1毫(háo)米，傾(qīng)斜角不得(dé)大于(yú)1度(dù)。安(ān)裝聯(lián)軸器時不(bú)得用錘敲(qiāo)打，以免(miǎn)傷(shāng)害齒輪泵的齒輪等(děng)零件。若用帶輪(lún)、鍊輪等驅動時(shí)應設托架(jià)支承(chéng)，以防主動齒輪(lún)軸承受(shòu)徑向力。緊固(gù)齒輪泵、電動機(jī)的地(dì)腳螺(luó)釘時(shí)，螺(luó)釘受力應均勻，連(lián)接可靠。用手轉(zhuǎn)動聯(lián)軸器時，應(yīng)感覺到(dào)齒(chǐ)輪泵能夠(gòu)輕松(sōng)地(dì)轉(zhuǎn)動，沒(méi)有卡(kǎ)緊(jǐn)等異常(cháng)現象出現，然後(hòu)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 than0.1 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)粘度齒輪泵的(de)吸油(yóu)管道(dào)内(nèi)徑(jìng)應足(zú)夠大(dà)，并避(bì)免狹窄通(tōng)道或(huò)急劇拐彎、減少(shǎo)彎頭，去除不必(bì)要的閥門、附件(jiàn)，盡可能地降低(dī)泵的安裝高度，縮短吸油管道(dào)的長度(dù)，以減少(shǎo)壓力(lì)損(sǔn)失。管(guǎn)接頭等(děng)元(yuán)件(jiàn)的密封要良好，以防止空氣侵(qīn)入，從而(ér)控制(zhì)氣(qì)穴與(yǔ)氣蝕的發生。止回閥與安全閥(fá)在齒輪泵(bèng)的輸出管(guǎn)路上安裝(zhuāng)一個止回(huí)閥。這(zhè)樣在(zài)檢修泵(bèng)及(jí)輸出管(guǎn)道時，系統中的液體不(bú)會發生倒流。齒(chǐ)輪泵帶(dài)負荷停(tíng)車時(shí)，亦可防止(zhǐ)泵倒轉而(ér)在其(qí)輸出管道(dào)内産(chǎn)生局(jú)部真(zhēn)空。應(yīng)當注意，出口止(zhǐ)回閥(fá)不能裝反或出現卡(kǎ)死現(xiàn)象。高粘(zhān)度(dù)泵的(de)出口(kǒu)管路(lù)上還(hái)應(yīng)當設置安全(quán)閥等保(bǎo)護裝(zhuāng)置(zhì)，這樣一旦(dàn)泵的(de)出口通(tōng)道(dào)發生堵塞(sāi)，就可以打(dǎ)開安全閥(fá)卸壓(yā)。安全(quán)閥可以與(yǔ)泵體或泵(bèng)蓋鑄(zhù)成一(yī)體，也可以(yǐ)單獨(dú)裝配(pèi)。對于(yú)需要(yào)正反轉的(de)高粘度齒輪(lún)泵(bèng)，其進(jìn)出口管路(lù)上均需(xū)設(shè)置安(ān)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(bèng)是(shì)輸(shū)送高(gāo)粘度(dù)液體的齒輪泵(bèng)，應做(zuò)到在(zài)較低的功耗、較少的(de)洩漏、較大(dà)的壓力下輸出最多(duō)的流量。在确定所要輸送的介(jiè)質時，應(yīng)該嚴格(gé)遵循(xún)産(chǎn)品說明(míng)書(shū)上的規定，盡(jìn)量使(shǐ)用廠家推薦的流體介質，并注(zhù)意(yì)考慮系統的工作溫度(dù)範圍。當(dāng)希望在(zài)某一較(jiào)寬的(de)溫(wēn)度範(fàn)圍内使用(yòng)時，輸(shū)送介質的(de)粘度(dù)指數應該(gāi)高些。輸送介質(zhì)不僅是(shì)能(néng)量(liàng)傳(chuán)遞的中介，而且(qiě)也是(shì)潤滑、密封(fēng)及傳(chuán)熱介質。液(yè)體粘度過高會(huì)增加内摩擦(cā)阻(zǔ)力，降低輸出功(gōng)率，浪費(fèi)能量，并(bìng)産生過(guò)高的系統溫度.高(gāo)粘度(dù)齒輪(lún)泵的(de)出(chū)口(kǒu)管路(lù)上應當設置安全(quán)閥等保(bǎo)護裝置，這樣一旦泵(bèng)的出口通(tōng)道發生堵(dǔ)塞，就(jiù)可以打開安全(quán)閥卸(xiè)壓。對于需要正反轉的高(gāo)粘度齒輪泵，其(qí)進出口管路上(shàng)均需(xū)設置(zhì)安全閥。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.

  ●起動(dòng)前要(yào)檢查下列内(nèi)容(róng)：

    1.檢查(chá)泵、齒輪箱(xiāng)和電(diàn)機的(de)對中(zhōng)程度；

    2.檢(jiǎn)查(chá)過濾(lǜ)器中(zhōng)有沒有焊皮和(hé)金屬渣(zhā)；

    3.檢(jiǎn)查各(gè)連接部位連接(jiē)是否緊固；

    4.檢查管路壓在(zài)泵上(shàng)的力和(hé)力矩是否超過給(gěi)定的(de)數值(zhí)，如果溫度(dù)較高(gāo)，還應檢查(chá)管路(lù)是否(fǒu)有膨(péng)脹節(jiē)；

    5.檢(jiǎn)查電氣(qì)連接的正(zhèng)确性(xìng)及電(diàn)機的額定(dìng)值，并(bìng)檢查電機(jī)轉(zhuǎn)動方向是否(fǒu)正确；

    6.檢查(chá)泵的(de)轉動方向是否(fǒu)正确(què)；

    7.如有(yǒu)安全(quán)閥，安(ān)全閥安裝(zhuāng)必須正确(què)，

    8.檢查(chá)泵軸是否轉動靈活(huó)；

    9.泵(bèng)的(de)内部(bù)不能(néng)是幹的，特(tè)别是(shì)需(xū)要自吸的時(shí)候，應向泵(bèng)内灌注一(yī)些油或輸(shū)送的液體(tǐ)；

    10.泵組(zǔ)裝時在零件的(de)表面有防(fáng)護液(yè)，如果(guǒ)這種(zhǒng)液體不能和泵(bèng)送液(yè)體相容，則(zé)必須(xū)清洗(xǐ)；

    11.在管(guǎn)路上(shàng)安裝壓力(lì)表(biǎo)和(hé)真空表，方(fāng)便觀察(chá)泵(bèng)的工(gōng)作狀态(tài)；

    12.檢查機械密封箱是否(fǒu)注滿液體(tǐ)；

    13.檢查管路的(de)閥門是(shì)否打開；

    14.如果用内燃機驅(qū)動，請(qǐng)在起動發動機(jī)前保持離合器脫(tuō)開；

    泵起動後(hòu)，檢查液體是否進入到(dào)泵中，泵是否工作(zuò)正常(cháng)，如果長(zhǎng)時(shí)間無(wú)液體進入泵中，應停機檢查泵(bèng)及管路。
