●高粘度齒輪泵(bèng)适用範圍:

   ●高粘度(dù)齒輪泵(bèng)并不能(néng)産生壓力，它(tā)隻是輸出(chū)流量。壓力低或(huò)無壓(yā)力(lì)，說明高(gāo)粘度齒 輪泵沒有吸入液體(tǐ)或(huò)洩漏嚴重。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(shū)出功率偏(piān)小、齒 輪(lún)泵(bèng)排量(liàng)選得過(guò)大或壓(yā)力調得過高(gāo)時，也會造成壓力(lì)不足 當然，壓力(lì)表損(sǔn)壞或壓力(lì)表(biǎo)節(jiē)流(liú)孔(kǒng)堵塞(sāi)時也顯示(shì)不出(chū)壓力，此時(shí)可換(huàn)裝一個(gè)新的壓(yā)力表(biǎo)檢(jiǎn)查。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(què)認泵無流量(liàng)輸出(chū)，可能(néng)是由于泵安裝有誤(wù)、泵的轉(zhuǎn)向(xiàng)不對(duì)，或吸(xī)人側(進液(yè)口及吸液管道(dào))堵塞、出口止回(huí)閥裝反或(huò)卡死(sǐ)了，也有(yǒu)可(kě)能是(shì)驅動(dòng)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)度泵在轉(zhuǎn)速過低時會引(yǐn)起出(chū)液(yè)量(liàng)不足(zú)，這種(zhǒng)現象往往(wǎng)是由于泵的驅動裝(zhuāng)置打滑或(huò)功率不(bú)足(zú)所緻(zhì)。此時應檢查齒(chǐ) 輪泵的(de)實(shí)際轉(zhuǎn)速、泵(bèng)與(yǔ)電(diàn)動機的聯(lián)接及功率(lǜ)匹配(pèi)情況等。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(dù)泵在(zài)開始(shǐ)運轉前，往(wǎng)齒輪泵的(de)殼體(tǐ)内灌滿待輸送的液(yè)體，便(biàn)于安全啟(qǐ)動。若環境溫度(dù)低于(yú)冰點，應預(yù)先向泵内(nèi)通入(rù)熱蒸汽(qì)，進行預(yù)熱處理，然後才(cái)可啟動(dòng)齒(chǐ)輪泵(bèng)。高粘度泵(bèng)的旋轉方(fāng)向要與進(jìn)、出油口(kǒu)相符。齒(chǐ)輪泵若(ruò)是(shì)第一(yī)次運(yùn)行(háng)，或長期(qī)閑置(zhì)後(hòu)再使用(yòng)，在空載或(huò)小負(fù)荷情(qíng)況下先跑(pǎo)合一小時(shí)左(zuǒ)右。如果在跑(pǎo)合階(jiē)段預先(xiān)覺察出(chū)異常溫升、洩漏(lòu)、振動和噪聲時，應停(tíng)機檢查。高粘度齒輪(lún)泵的支座或法蘭與(yǔ)其驅動電機應采用共同的安(ān)裝基(jī)礎，基礎、法蘭或支座(zuò)均需(xū)具有足夠的剛度，以減(jiǎn)小(xiǎo)齒輪(lún)泵(bèng)運轉時産生(shēng)的振動和噪(zào)聲(shēng)。電動機(jī)與齒輪泵須用彈性聯軸器連接(jiē)，同軸度小于(yú)0.1毫米，傾(qīng)斜角(jiǎo)不得(dé)大(dà)于1度。安裝(zhuāng)聯軸器(qì)時不得用(yòng)錘敲(qiāo)打，以(yǐ)免傷害齒(chǐ)輪泵的齒(chǐ)輪等(děng)零件。若用帶輪、鍊輪等驅(qū)動時(shí)應設(shè)托(tuō)架支承(chéng)，以防主動(dòng)齒輪(lún)軸承受徑向力(lì)。緊固齒輪(lún)泵、電動機(jī)的地腳螺(luó)釘時，螺(luó)釘(dìng)受力應均(jun1)勻，連接可(kě)靠。用手(shǒu)轉(zhuǎn)動聯(lián)軸器(qì)時，應感覺到齒輪(lún)泵(bèng)能夠(gòu)輕松地轉動，沒(méi)有卡(kǎ)緊等(děng)異常現象(xiàng)出現，然後(hòu)才可以配管。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 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(lún)泵的(de)吸油管(guǎn)道内徑(jìng)應足(zú)夠大，并避(bì)免(miǎn)狹窄通(tōng)道或(huò)急劇拐彎、減少(shǎo)彎頭，去(qù)除(chú)不必要的(de)閥門、附件，盡可能地降低(dī)泵的(de)安裝高度(dù)，縮短吸(xī)油管(guǎn)道的長(zhǎng)度，以減少壓力損(sǔn)失(shī)。管接(jiē)頭等元(yuán)件的密(mì)封(fēng)要良好(hǎo)，以防止空氣(qì)侵入，從(cóng)而控制氣穴與氣蝕(shí)的發生。止回閥(fá)與安(ān)全閥在齒輪(lún)泵(bèng)的輸(shū)出管路上安裝一個止回(huí)閥。這(zhè)樣在(zài)檢修泵及輸出(chū)管(guǎn)道時，系(xì)統中的液體不(bú)會發(fā)生倒流。齒輪泵帶負(fù)荷停車時，亦(yì)可防止(zhǐ)泵倒(dǎo)轉而在其(qí)輸(shū)出管道内産(chǎn)生局部真空。應(yīng)當注意，出口止(zhǐ)回閥不能(néng)裝反(fǎn)或出現(xiàn)卡死現(xiàn)象。高粘度泵的出口管路上還(hái)應當設置(zhì)安全(quán)閥等保護裝置(zhì)，這樣(yàng)一旦泵的(de)出(chū)口通道發生(shēng)堵塞，就可(kě)以打(dǎ)開安(ān)全閥(fá)卸壓(yā)。安全閥(fá)可(kě)以與泵體(tǐ)或泵蓋鑄(zhù)成(chéng)一(yī)體(tǐ)，也(yě)可以(yǐ)單獨裝配。對于(yú)需要正反(fǎn)轉的(de)高粘度(dù)齒輪泵(bèng)，其進(jìn)出口管路(lù)上(shàng)均(jun1)需(xū)設(shè)置安(ān)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(zhān)度泵(bèng)是輸(shū)送高粘度(dù)液體的齒(chǐ)輪泵(bèng)，應做(zuò)到在較低的功耗、較少的洩漏(lòu)、較(jiào)大的壓(yā)力下輸出最多(duō)的流量(liàng)。在(zài)确定(dìng)所要輸送(sòng)的介(jiè)質(zhì)時(shí)，應該嚴格(gé)遵循産品說(shuō)明(míng)書上的規(guī)定，盡(jìn)量使用(yòng)廠家推薦的(de)流體介質(zhì)，并注意考慮系(xì)統的工作溫(wēn)度(dù)範圍。當希(xī)望在某一(yī)較寬的溫(wēn)度範圍内使用時，輸送介質的(de)粘度指(zhǐ)數應該(gāi)高些。輸送介質(zhì)不僅是能量傳(chuán)遞的中(zhōng)介，而且也(yě)是潤滑(huá)、密封(fēng)及傳(chuán)熱介質(zhì)。液(yè)體粘度過高會(huì)增加(jiā)内(nèi)摩擦阻力，降低輸出功率，浪費能量，并(bìng)産生過高(gāo)的(de)系統溫(wēn)度.高粘度(dù)齒輪泵的出口管路上(shàng)應當設(shè)置安全閥等保護裝置，這樣一旦泵的出(chū)口通(tōng)道發生堵(dǔ)塞，就(jiù)可以(yǐ)打開(kāi)安全(quán)閥卸(xiè)壓。對(duì)于需(xū)要正反(fǎn)轉(zhuǎn)的(de)高粘度齒(chǐ)輪(lún)泵，其(qí)進出口(kǒu)管路上均需(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.

   1、工作壓(yā)力的(de)選定1, select the work pressure

　　高粘度泵(bèng)額定的壓(yā)力是(shì)指泵(bèng)連續工作(zuò)時的最高(gāo)許用壓力，而其工作(zuò)壓力則(zé)決定于(yú)外部(bù)負(fù)載(zǎi)，安裝和調(diào)試的壽命與其(qí)工作壓力(lì)直接相關(guān)。對于(yú)不頻繁工作的(de)齒輪泵，其工作壓力可(kě)取為泵(bèng)的額(é)定壓力，考慮到(dào)産(chǎn)品質量(liàng)不同，将(jiāng)額(é)定壓(yā)力降低20%～30%使用。對(duì)于經(jīng)常工(gōng)作于(yú)較高壓力下的齒輪泵(bèng)，其工作(zuò)壓力應比泵的(de)額定(dìng)壓力低1～2個(gè)壓力(lì)級。石油化(huà)工設(shè)備(bèi)常(cháng)常是(shì)24小時連續運轉(zhuǎn)，這時泵(bèng)的工作壓力(lì)應該(gāi)取得(dé)比額定壓力低得多(duō)，且工作轉(zhuǎn)速(sù)也(yě)應該低于(yú)額定轉速。如(rú)果(guǒ)高粘度(dù)齒(chǐ)輪泵的工作壓力調(diào)整過(guò)高，則(zé)會使齒輪泵在超負(fù)荷下運行。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.
