     高粘(zhān)度液體齒輪(lún)泵(bèng)的吸油(yóu)管道内(nèi)徑應足夠(gòu)大，并(bìng)避免狹窄通道(dào)或急劇(jù)拐(guǎi)彎、減(jiǎn)少彎(wān)頭，去除(chú)不(bú)必要的閥(fá)門、附(fù)件，盡(jìn)可能地降(jiàng)低泵(bèng)的(de)安裝高(gāo)度(dù)，縮(suō)短吸油管(guǎn)道的長度(dù)，以(yǐ)減(jiǎn)少壓(yā)力損失。管(guǎn)接頭等(děng)元(yuán)件的密封(fēng)要良好，以(yǐ)防止空氣(qì)侵入(rù)，從而(ér)控制氣(qì)穴(xué)與氣蝕的(de)發生(shēng)。止回閥(fá)與安全閥在齒(chǐ)輪泵的(de)輸出管(guǎn)路上最(zuì)好安裝一個止(zhǐ)回閥(fá)。這樣(yàng)在檢(jiǎn)修泵(bèng)及(jí)輸(shū)出管道時(shí)，系統中的(de)液體不(bú)會發生倒流。齒輪泵帶(dài)負荷停車(chē)時，亦(yì)可防(fáng)止(zhǐ)泵倒轉(zhuǎn)而在其輸(shū)出管(guǎn)道内産生局部(bù)真空。應當(dāng)注意(yì)，出口止(zhǐ)回(huí)閥不(bú)能裝反或出現卡死(sǐ)現象。高粘(zhān)度(dù)泵的出(chū)口管(guǎn)路上還應當(dāng)設(shè)置安(ān)全閥等保(bǎo)護裝(zhuāng)置(zhì)，這樣一(yī)旦泵(bèng)的出(chū)口通(tōng)道發生堵塞，就(jiù)可以打開安全閥卸(xiè)壓。安全閥(fá)可以與泵體或(huò)泵蓋(gài)鑄成一體(tǐ)，也可以單獨裝(zhuāng)配。對于需要(yào)正反轉的(de)高(gāo)粘度(dù)齒輪泵，其進出(chū)口管(guǎn)路上(shàng)均需設(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(gāo)粘度液體齒輪(lún)泵是(shì)輸送(sòng)高粘(zhān)度液(yè)體的齒輪(lún)泵，應(yīng)做到在較(jiào)低的功耗、較少的洩(xiè)漏、較(jiào)大(dà)的(de)壓力下(xià)輸(shū)出最(zuì)多的流量。在确(què)定所要輸送的(de)介質(zhì)時，應該嚴(yán)格遵循(xún)産品說(shuō)明書上的規定(dìng)，盡量使用廠家(jiā)推薦(jiàn)的(de)流體介(jiè)質，并注意考慮(lǜ)系統(tǒng)的工(gōng)作溫(wēn)度範圍。當(dāng)希望在某(mǒu)一較寬的(de)溫度範(fàn)圍内使用時，輸送介質(zhì)的粘(zhān)度指數應(yīng)該高(gāo)些(xiē)。輸送介(jiè)質不僅(jǐn)是能量傳遞(dì)的中介，而(ér)且也是潤滑、密(mì)封及傳熱介質。液體粘度過高會增加内摩擦(cā)阻力(lì)，降(jiàng)低輸出(chū)功率，浪費能量(liàng)，并産生過(guò)高的(de)系統溫度(dù).高粘(zhān)度齒(chǐ)輪泵的出口管(guǎn)路(lù)上(shàng)應當(dāng)設置安全(quán)閥等(děng)保護裝置，這樣(yàng)一旦泵的出口通道(dào)發(fā)生堵塞(sāi)，就可以打開安全(quán)閥卸壓。對于(yú)需要(yào)正反(fǎn)轉(zhuǎn)的高粘(zhān)度齒輪泵，其進出(chū)口管路上均需設置安全閥。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.

    1、工作壓力(lì)的選(xuǎn)定1, select the work pressure

　　高粘度(dù)液體齒輪泵額(é)定的(de)壓(yā)力是指(zhǐ)泵連續工作時(shí)的最(zuì)高許用壓(yā)力，而其(qí)工作壓(yā)力則(zé)決定于外(wài)部負載，安裝和(hé)調試(shì)的壽命與(yǔ)其工作壓力直(zhí)接相(xiàng)關。對于不(bú)頻繁工作(zuò)的齒輪泵，其工(gōng)作壓(yā)力可(kě)取為泵的額定(dìng)壓力，考慮(lǜ)到産品(pǐn)質量不(bú)同，最好将額定(dìng)壓力降低(dī)20%～30%使用(yòng)。對于(yú)經常(cháng)工作(zuò)于(yú)較高(gāo)壓(yā)力下的齒輪泵，其工(gōng)作壓力應比泵(bèng)的額定壓力低(dī)1～2個壓力級。石油(yóu)化(huà)工設備(bèi)常常(cháng)是24小時連續運(yùn)轉，這(zhè)時泵的工(gōng)作壓力應該取(qǔ)得比(bǐ)額定壓力低得(dé)多(duō)，且工作(zuò)轉速(sù)也應該低(dī)于額定轉(zhuǎn)速。如(rú)果高粘(zhān)度齒輪(lún)泵的(de)工作(zuò)壓力(lì)調整過高，則會(huì)使齒輪泵(bèng)在超(chāo)負荷(hé)下(xià)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.
