●高粘度(dù)泵優點(diǎn)：

　　轉子泵(bèng)的軸向(xiàng)位置可(ke)調，不需(xu)要拆泵(bèng)。

　　泵采用(yòng)模塊化(huà)設計，可(ke)根據不(bu)同的使(shǐ)用要求(qiu)更換⭐不(bu)同部件(jiàn)。可選夾(jiá)層結構(gou)，以方便(biàn)對泵加(jia)熱或冷(leng)卻，可以(yǐ)選擇是(shì)否☀️帶安(ān)💛全閥，可(ke)以選擇(ze)不同的(de)密封形(xing)式，詳見(jiàn)密封結(jié)🔴構圖。泵(bèng)的各個(ge)零件可(kě)以選用(yong)不同的(de)材質以(yi)适應具(ju)體使用(yòng)要求。

　　不(bu)同的使(shi)用條件(jian)，泵的結(jie)構形式(shi)可能不(bu)同，具體(ti)應用請(qǐng)向廠👄家(jiā)或本公(gong)司客戶(hu)代表咨(zi)詢。需要(yao)指出的(de)是泵的(de)轉🈚速愈(yu)高，泵㊙️的(de)磨🏃‍♂️損愈(yu)嚴重，液(yè)體中如(rú)含有磨(mo)料物🐕質(zhì)，泵的材(cai)料應👉選(xuan)用耐磨(mó)材質，在(zai)此種工(gong)況下，泵(bèng)的壓力(li)和轉速(su)都應降(jiang)低，高溫(wēn)條件下(xia)，則應增(zēng)加泵的(de)間隙，并(bing)采用耐(nài)熱材料(liao) 。

　　流動穩(wen)定：流量(liang)與齒輪(lún)轉速成(cheng)正比，與(yu)壓力無(wu)關

　　流動(dòng)平穩：沒(méi)有脈動(dong)和壓力(lì)波峰，不(bú)會産生(sheng)管道顫(chàn)動。

　　多功(gong)能性：僅(jin)僅通過(guo)調整轉(zhuan)子軸的(de)位置，同(tong)一台泵(beng)💋既可✨以(yǐ)出來稀(xi)釋溶液(ye)又可以(yi)出來瀝(lì)青，糖漿(jiāng)，樹脂，聚(jù)合物等(deng)高粘度(du)液體。

　　堅固的(de)重載結(jié)構：低轉(zhuǎn)速。特大(da)球軸承(cheng)的外部(bù)軸承💃🏻座(zuò)可以承(cheng)受軸向(xiang)和徑向(xiang)負載。

　　磨(mo)損率低(di)：由于主(zhǔ)動輪和(hé)從動齒(chǐ)輪不成(cheng)倍數關(guān)系。這就(jiù)意味着(zhe)磨損可(ke)以被均(jun)勻的分(fèn)散在每(měi)個齒輪(lún)上。因為(wéi)一個齒(chi)輪上💜的(de)每一個(gè)齒輪接(jiē)觸另一(yi)個齒輪(lun)上的每(měi)一個齒(chǐ)輪的次(cì)數一樣(yang)。

磨損調(diao)節系統(tǒng)：轉子邊(bian)緣的磨(mo)損可以(yi)通過調(diao)整轉子(zǐ)軸的位(wei)置來補(bǔ)償。這樣(yàng)，即使在(zai)有相當(dāng)大的磨(mo)損⛷️的情(qing)📧況下，也(yě)可💋以保(bǎo)證泵🏒的(de)穩定性(xìng)。

　　維護簡(jiǎn)單，維護(hù)率低：不(bu)用移動(dòng)泵，管道(dào)或泵驅(qū)動裝♌置(zhi)就可以(yi)進行檢(jian)查和調(diao)節。

　　端口位(wei)置可改(gǎi)變：泵殼(ké)可在軸(zhou)承箱上(shang)旋轉以(yǐ)從不同(tong)👌位置♻️處(chù)吸排液(ye)體。

　　預熱(rè)：加熱夾(jiá)套或是(shì)與外殼(ké)鑄成一(yī)體，或是(shì)安裝在(zai)端蓋上(shàng)，或是安(ān)裝在填(tián)料壓蓋(gai)上。

●NYP高粘(zhan)度泵的(de)進出口(kǒu)

　　泵進出(chu)口的型(xíng)式

　　常規(gui)泵進出(chū)口尺寸(cun)相同，進(jin)出口呈(chéng)垂直布(bu)置，從驅(qū)🔆動機向(xiang)泵頭🎯方(fang)向看為(wéi)右進上(shàng)出。也可(kě)根據客(kè)戶需要(yào)，加工成(chéng)❤️水平進(jin)出👌口型(xing)或左進(jìn)上出型(xing)。連接方(fang)式有法(fǎ)蘭型和(hé)螺紋型(xíng).

　　泵進出(chu)口負荷(he)

　　泵在安(an)裝時，應(yīng)限制泵(beng)的進出(chū)口所承(cheng)受的管(guan)路負荷(he)。螺♌紋聯(lian)接的管(guǎn)接頭不(bu)得承受(shòu)負荷，否(fou)則會使(shǐ)泵的聯(lian)🌈接管産(chan)生松動(dòng)或旋緊(jin)力矩（管(guǎn)螺紋聯(lián)接處不(bu)👅允許有(yǒu)旋緊或(huo)松動的(de)扭矩，以(yi)免）影響(xiang)管路的(de)聯接效(xiào)果。

●NYP高粘(zhān)度泵的(de)起動

　　泵(bèng)在起動(dong)過程中(zhong)應特别(bié)注意以(yi)下幾個(ge)問題：

　　起(qǐ)動前要(yào)檢查下(xià)列内容(róng)：

　　檢查泵(beng)、齒輪箱(xiāng)和電機(ji)的對中(zhong)程度；

　　檢(jian)查過濾(lü)器中有(yǒu)沒有焊(han)皮和金(jin)屬渣；

　　檢(jian)查各連(lian)接部位(wèi)連接是(shi)否緊固(gù)；

　　檢查管(guǎn)路壓在(zài)泵上的(de)力和力(li)矩是否(fou)超過給(gěi)定的🐇數(shu)值，如♊果(guǒ)溫度較(jiao)高，還應(ying)檢查管(guan)路是否(fǒu)有膨脹(zhàng)節；

　　檢查(cha)電氣連(lian)接的正(zhèng)确性及(jí)電機的(de)額定值(zhí)，并檢查(cha)電機轉(zhuan)動🏒方✊向(xiang)是否正(zhèng)确；

　　檢查(cha)泵的轉(zhuǎn)動方向(xiàng)是否正(zhèng)确；

　　如有(yǒu)安全閥(fa)，安全閥(fá)安裝必(bi)須正确(que)，

　　檢查泵(bèng)軸是否(fou)轉動靈(líng)活；

　　泵的(de)内部不(bú)能是幹(gan)的，特别(bié)是需要(yào)自吸的(de)時候，應(ying)向泵内(nèi)灌注一(yi)些油或(huò)輸送的(de)液體；

　　泵(beng)組裝時(shí)在零件(jian)的表面(miàn)有防護(hu)液，如果(guǒ)這種液(ye)體不能(néng)和泵送(sòng)✨液體相(xiang)容，則必(bì)須清洗(xi)；

　　最好在(zai)管路上(shàng)安裝壓(ya)力表和(he)真空表(biǎo)，方便觀(guān)察泵的(de)工作狀(zhuàng)态；

　　檢查(chá)機械密(mi)封箱是(shì)否注滿(man)液體；

　　泵起動(dòng)後，檢查(cha)液體是(shi)否進入(ru)到泵中(zhōng)，泵是否(fou)工作💰正(zheng)常，如果(guǒ)長時間(jiān)無液體(ti)進入泵(bèng)中，應停(tíng)機檢查(cha)泵㊙️及管(guan)😄路。

●高粘(zhan)度齒輪(lún)泵并不(bu)能産生(sheng)壓力，它(ta)隻是輸(shū)出流量(liàng)。壓力低(di)或無壓(ya)力❗，說明(míng)高🌂粘度(du)齒 輪泵(beng)沒有吸(xī)入液體(ti)或洩漏(lòu)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(diàn)動機輸(shū)出功率(lü)偏小、齒(chǐ) 輪泵排(pái)量選得(de)過大或(huò)壓力調(diao)得過高(gao)時，也會(huì)造成壓(yā)力不足(zú) 當然，壓(yā)力表損(sun)壞或壓(yā)力📞表節(jiē)🏃🏻流孔堵(dǔ)塞時也(ye)顯示不(bu)出壓力(lì)，此時🈲可(ke)換裝一(yī)個新的(de)壓力表(biǎo)檢查。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(ru)果确認(rèn)泵無流(liu)量輸出(chū)，可能是(shì)由于泵(beng)安裝有(yǒu)誤、泵的(de)轉向不(bú)對，或吸(xī)人側(進(jìn)液口及(ji)吸液管(guǎn)道)堵塞(sāi)、出口止(zhi)回閥裝(zhuang)反或卡(kǎ)死了，也(ye)有可能(neng)是驅動(dòng)軸🚶‍♀️斷裂(liè)了。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(zai)轉速過(guo)低時會(hui)引起出(chu)液量不(bú)足，這種(zhǒng)現象往(wǎng)往是由(yóu)于泵的(de)驅動裝(zhuāng)置打滑(hua)或功率(lü)不足所(suo)緻。此時(shi)應檢查(chá)齒 輪泵(bèng)🔞的實際(ji)轉速、泵(beng)與電動(dòng)機的聯(lian)接及功(gōng)率匹配(pei)情況等(děng)。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.

     高粘度(dù)齒輪泵(bèng)的吸油(yóu)管道内(nèi)徑應足(zú)夠大，并(bing)避免狹(xiá)窄通道(dào)或急🏃‍♀️劇(jù)拐彎、減(jian)少彎頭(tóu)，去除不(bú)必要的(de)閥門、附(fu)件，盡可(kě)能地降(jiàng)💋低泵🚩的(de)安裝高(gāo)度，縮短(duǎn)吸油管(guan)道的長(zhang)度，以減(jian)☀️少壓力(lì)🍉損失。管(guan)接頭等(deng)元件的(de)密封要(yào)良好，以(yǐ)防止空(kong)氣侵入(rù)✏️，從而控(kòng)制氣穴(xue)與氣蝕(shi)的發生(shēng)。止回閥(fa)與安全(quán)閥在齒(chǐ)輪泵的(de)輸出管(guan)路上最(zui)好安裝(zhuāng)一個止(zhǐ)回閥。這(zhe)樣在檢(jiǎn)修泵及(ji)輸㊙️出管(guan)道時，系(xì)統中的(de)液體不(bu)會發生(shēng)倒流。齒(chǐ)輪泵帶(dài)負荷停(tíng)車時，亦(yì)可防止(zhǐ)泵倒轉(zhuan)而在其(qí)輸出管(guan)道内産(chǎn)生局部(bù)真空。應(yīng)當注意(yì)，出口止(zhǐ)回閥不(bú)能裝反(fan)或出💃🏻現(xiàn)卡死現(xiàn)象。高粘(zhan)度泵的(de)出口管(guan)路上還(hái)應當設(shè)置安💃🏻全(quan)閥等保(bao)護裝置(zhì)，這樣一(yī)旦泵的(de)出口通(tōng)道🎯發生(shēng)堵塞，就(jiu)可以打(da)🥰開安全(quan)閥卸壓(yā)。安全閥(fa)可以與(yǔ)泵體或(huò)泵蓋鑄(zhù)成一體(tǐ)，也可以(yǐ)單獨裝(zhuāng)配。對于(yú)需要正(zhèng)反轉的(de)高粘度(dù)齒輪泵(beng)，其進出(chū)口管路(lù)上均需(xu)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(gao)粘度泵(beng)是輸送(song)高粘度(dù)液體的(de)齒輪泵(beng)，應做到(dào)在較低(dī)的功耗(hào)、較少的(de)洩漏、較(jiào)大的壓(yā)力下輸(shū)出最多(duo)的流量(liàng)。在确定(dìng)所要輸(shu)送的介(jie)質時，應(ying)該嚴格(gé)遵循産(chǎn)品說明(míng)書上的(de)規定，盡(jin)量使用(yong)廠家推(tui)薦的流(liú)✍️體介質(zhì)，并注意(yì)考慮系(xì)統的工(gōng)作溫度(dù)範圍。當(dang)希望在(zài)某一較(jiao)寬的溫(wēn)度範圍(wéi)内使用(yong)時，輸送(song)介質的(de)粘度指(zhǐ)數應該(gai)高些。輸(shu)送介質(zhi)不僅是(shi)能量傳(chuán)遞的中(zhong)介，而且(qie)📐也是潤(run)滑、密封(fēng)及傳熱(rè)介質。液(ye)體粘度(dù)過高會(hui)增加内(nèi)摩擦阻(zǔ)力，降低(di)輸出功(gong)率，浪費(fèi)能量，并(bing)産生過(guo)高的系(xi)統溫度(du).高粘度(du)齒輪泵(beng)的出口(kǒu)管路上(shang)應當設(shè)置安全(quán)閥等保(bao)護裝置(zhì)，這樣一(yi)📱旦泵的(de)出🌐口通(tōng)道發生(shēng)堵塞，就(jiù)可以打(dǎ)開安全(quán)閥卸壓(ya)。對于需(xu)要正反(fan)轉的高(gāo)粘度齒(chi)輪泵，其(qí)進出口(kou)管路上(shang)均需設(shè)置安全(quan)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.
