　　高(gao)粘度泵(beng)是容積(ji)式内齧(niè)合齒輪(lún)泵，主動(dong)齒輪（外(wai)轉子）帶(dai)動被動(dòng)齒輪（内(nei)轉子）旋(xuán)轉時，不(bu)斷💋産生(shēng)封閉的(de)空間，在(zai)吸油區(qū)齒輪逐(zhú)漸脫離(lí)齧合而(ér)液💃🏻體不(bú)斷地充(chōng)滿齒間(jian)👣并被帶(dài)到出油(you)區，齒輪(lún)在出油(yóu)區🐉進入(rù)齧合時(shí)液體被(bèi)排出。兩(liǎng)個旋轉(zhuǎn)齒輪的(de)共同作(zuo)用，形成(chéng)一個穩(wen)定的體(tǐ)積排量(liang)，沒有脈(mo)動。由于(yu)泵是完(wan)全對稱(chēng)的，泵可(ke)以反轉(zhuǎn)，液流🙇‍♀️方(fang)向也随(sui)之🔞改變(biàn)。但應注(zhù)意🔞，泵的(de)轉向可(ke)能受到(dao)密封或(huò)泵👄内其(qi)它結構(gou)的🌐限制(zhì)，用戶有(you)反轉要(yào)求時應(yīng)在訂貨(huò)時做出(chu)說明。

　　不同(tóng)的使用(yong)條件，泵(beng)的結構(gou)形式可(kě)能不同(tóng)，具體應(ying)用請💘向(xiàng)廠家或(huo)本公司(sī)客戶代(dài)表咨詢(xún)。需要指(zhǐ)出的是(shì)泵💯的轉(zhuǎn)速愈高(gao)，泵的磨(mó)損愈嚴(yan)重，液體(tǐ)中如含(hán)有磨料(liao)物🈲質，泵(bèng)的材料(liào)應選用(yòng)耐磨材(cai)質，在此(ci)種工況(kuàng)下，泵的(de)壓力和(he)轉速都(dōu)應降低(dī)，高溫條(tiáo)件下，則(zé)應增✍️加(jiā)泵的間(jian)隙，并采(cǎi)用耐熱(re)材料 。

　　流(liu)動穩定(dìng)：流量與(yu)齒輪轉(zhuan)速成正(zhèng)比，與壓(yā)力無關(guān)

　　流動平(píng)穩：沒有(you)脈動和(hé)壓力波(bo)峰，不會(hui)産生管(guǎn)道顫‼️動(dòng)。

　　多功能(neng)性：僅僅(jin)通過調(diao)整轉子(zi)軸的位(wei)置，同一(yī)台泵既(jì)可以📱出(chu)來稀釋(shi)溶液又(yòu)可以出(chu)來瀝青(qing)，糖漿，樹(shù)脂🐇，聚合(hé)物等高(gao)粘度液(ye)🔆體。

　　磨損(sǔn)率低：由(yóu)于主動(dong)輪和從(cong)動齒輪(lun)不成倍(bei)數關系(xì)。這就意(yì)⛱️味着磨(mó)損可以(yǐ)被均勻(yún)的分散(sàn)在每個(ge)齒輪上(shang)。因為一(yī)✉️個齒輪(lún)上的每(mei)一個齒(chi)輪接觸(chù)另一個(gè)齒輪上(shang)的每一(yi)個齒輪(lun)的次數(shu)一樣。

　　1, select the work pressure

　　高粘度(du)泵額定(ding)的壓力(lì)是指泵(bèng)連續工(gōng)作時的(de)最高許(xu)用🐇壓力(lì)，而其工(gong)作壓力(li)則決定(ding)于外部(bù)負載，安(an)裝和調(diào)試的壽(shou)命與其(qí)工作壓(ya)力直接(jiē)相關。對(dui)于不頻(pin)繁工作(zuo)的齒輪(lún)泵，其工(gong)作壓力(lì)可取為(wéi)泵的額(e)定壓力(lì)，考慮到(dào)産品質(zhi)量不同(tóng)，最好将(jiang)額定壓(ya)力降低(di)20%～30%使用。對(duì)于經常(chang)工作于(yu)較高壓(yā)力下的(de)齒輪泵(beng)，其工作(zuò)壓力應(ying)比泵的(de)額定壓(ya)力低1～2個(ge)壓力級(ji)。石油化(hua)工設備(bèi)常常是(shì)24小時連(lian)續運轉(zhuan)，這時泵(bèng)的工作(zuò)壓力應(ying)該取得(dé)比額定(dìng)壓力🧑🏽‍🤝‍🧑🏻低(dī)得多，且(qiě)工作轉(zhuǎn)速也應(ying)該低于(yu)額定轉(zhuan)速。如果(guo)高粘度(du)齒輪泵(bèng)的工作(zuo)壓力調(diao)整過高(gao)，則會使(shǐ)齒輪泵(beng)在超負(fù)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.
