     高粘(zhān)度液(yè)體齒輪(lún)泵的吸油管(guǎn)道内(nèi)徑應足(zú)夠大，并避免狹窄通道或(huò)急劇拐彎、減少彎頭，去(qù)除(chú)不(bú)必要的(de)閥門、附件，盡(jìn)可(kě)能地降(jiàng)低泵的安裝高度，縮短吸(xī)油管(guǎn)道的(de)長度，以減少壓(yā)力損(sǔn)失。管(guǎn)接頭(tóu)等元件的密封(fēng)要良好，以(yǐ)防止空氣(qì)侵入(rù)，從而控(kòng)制氣穴(xué)與氣蝕的發生(shēng)。止回(huí)閥與安全(quán)閥在(zài)齒輪(lún)泵的(de)輸(shū)出管路上最(zuì)好安裝一(yī)個止回閥。這樣在檢(jiǎn)修泵及(jí)輸(shū)出管(guǎn)道時(shí)，系統中的(de)液體不會(huì)發生倒流。齒輪(lún)泵帶(dài)負荷停車時，亦(yì)可防(fáng)止泵倒轉(zhuǎn)而在(zài)其輸(shū)出管道内(nèi)産(chǎn)生局部(bù)真空(kōng)。應當注意(yì)，出口(kǒu)止(zhǐ)回(huí)閥不(bú)能裝反或出現(xiàn)卡死(sǐ)現(xiàn)象。高粘(zhān)度泵的出口管(guǎn)路上(shàng)還應當設(shè)置安(ān)全閥(fá)等保護裝(zhuāng)置(zhì)，這樣一(yī)旦泵的出口通(tōng)道發生(shēng)堵(dǔ)塞，就(jiù)可以(yǐ)打(dǎ)開(kāi)安(ān)全閥卸壓。安全閥(fá)可以與(yǔ)泵體或泵蓋(gài)鑄成一體，也可(kě)以單獨裝(zhuāng)配。對(duì)于需要(yào)正反轉的高粘度(dù)齒輪泵，其進出(chū)口管路上均需(xū)設置安(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(tǐ)齒輪泵是輸送高粘(zhān)度液體的(de)齒輪(lún)泵，應(yīng)做(zuò)到(dào)在較(jiào)低的(de)功耗、較少的洩漏、較大的壓力下(xià)輸出最(zuì)多的(de)流量。在确(què)定所要輸送的介質時，應該嚴(yán)格遵循産(chǎn)品說明書上的規定(dìng)，盡量使用廠家推薦的(de)流體介(jiè)質，并注意考慮(lǜ)系統(tǒng)的工作溫(wēn)度範圍。當(dāng)希望在某(mǒu)一較寬的溫度範圍(wéi)内使(shǐ)用時，輸送介質(zhì)的粘度指數應該高些。輸送介質不僅(jǐn)是(shì)能量(liàng)傳遞(dì)的(de)中介，而(ér)且也(yě)是潤(rùn)滑、密(mì)封及(jí)傳熱介質。液體粘度(dù)過高(gāo)會增加(jiā)内摩擦(cā)阻力，降低輸出功率，浪費(fèi)能量(liàng)，并産(chǎn)生過(guò)高的(de)系統溫度.高粘(zhān)度齒輪泵的出口管路上(shàng)應當設(shè)置安全(quán)閥等(děng)保護裝置，這樣(yàng)一旦泵(bèng)的出口通道發生堵塞(sāi)，就可(kě)以打開安全閥卸(xiè)壓。對于(yú)需要(yào)正反轉的(de)高粘度齒(chǐ)輪泵(bèng)，其進出口(kǒu)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(zuò)壓力(lì)的選定1, select the work pressure

　　高粘(zhān)度(dù)液體(tǐ)齒(chǐ)輪泵額(é)定的(de)壓(yā)力是指(zhǐ)泵連續工作時(shí)的最高許用壓(yā)力，而其工作壓力則(zé)決定于外(wài)部負載(zǎi)，安裝和(hé)調試的壽命與其(qí)工作壓力直(zhí)接相(xiàng)關。對于不(bú)頻繁工作(zuò)的齒(chǐ)輪泵，其工作壓(yā)力可取(qǔ)為泵的額定壓(yā)力，考慮(lǜ)到産品質量不(bú)同，最好将(jiāng)額定(dìng)壓力降低20%～30%使用(yòng)。對于(yú)經常工作(zuò)于(yú)較高壓力下(xià)的齒輪泵(bèng)，其工(gōng)作壓力(lì)應(yīng)比泵(bèng)的額(é)定(dìng)壓力低1～2個壓(yā)力級(jí)。石油(yóu)化工設備常常(cháng)是24小時(shí)連(lián)續運轉，這(zhè)時泵的工(gōng)作壓力應該取得比(bǐ)額(é)定壓力(lì)低得多，且工作(zuò)轉速也應(yīng)該低(dī)于額(é)定轉(zhuǎn)速。如(rú)果高(gāo)粘度齒輪(lún)泵的工(gōng)作(zuò)壓力(lì)調整過高，則會(huì)使齒輪泵在(zài)超負荷下運(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.
