　　高粘度泵是容(róng)積式内齧合齒輪泵，主動齒輪（外(wài)轉子）帶動被動齒輪（内轉子）旋轉時，不(bú)斷産生封閉的空間，在吸油(yóu)區齒輪逐漸脫離齧合(hé)而液體不斷地(dì)充滿齒(chǐ)間并被帶到(dào)出油區，齒(chǐ)輪在出油區進入齧合時液體被排出。兩個旋轉齒輪的共同作用，形成一個穩定的體積排量(liàng)，沒(méi)有脈動。由于泵是(shì)完全對稱的，泵可以(yǐ)反轉，液流方向(xiàng)也(yě)随之改變。但應注意，泵的轉向可能受到(dào)密(mì)封或泵内其它結(jié)構的限制(zhì)，用戶有反轉要求時應在訂貨時做(zuò)出說明。　　

●高粘度泵優點：

　　轉子泵的軸(zhóu)向位置可調，不需要(yào)拆泵。

　　泵采用模(mó)塊化設計，可根(gēn)據不同的使用要求(qiú)更換不同(tóng)部件。可選夾(jiá)層結構，以方便對泵加熱或冷卻，可以(yǐ)選擇是否帶安全閥，可以選擇不同的密封形式，詳見密封結構圖。泵的各個零件可以選用不同的(de)材質以适應具體使用要求。

　　不同的使用條件，泵的結(jié)構形式可能不同(tóng)，具體應用請向廠(chǎng)家或本公(gōng)司客戶代表咨詢。需要指出的是泵的轉速(sù)愈高，泵的磨損愈(yù)嚴重，液體中如含有磨料物質，泵的材料應選(xuǎn)用耐磨材質，在此種工況(kuàng)下，泵的壓力和轉速都應降低，高溫(wēn)條件下，則應增加(jiā)泵的間隙，并(bìng)采用耐熱材料 。

　　流動穩(wěn)定：流量與齒輪轉(zhuǎn)速成正比，與(yǔ)壓力無關

　　流動平穩：沒有脈動和壓力波峰，不(bú)會産生管道顫動。

　　多功(gōng)能性：僅僅通過(guò)調整(zhěng)轉子軸的(de)位置，同一台泵既可以出來稀(xī)釋溶液又可以出來瀝青，糖漿，樹脂，聚合物等高粘度液體。

　　可(kě)逆性：可以通過改變齒輪的(de)旋轉方向使液體反向流動，兩種方向都能充分發揮泵的性能(néng)

　　自吸性：由泵産生高真空(kōng)，允許(xǔ)在最大自吸高度實(shí)現快速自(zì)吸，取決于泵送液體的物理特性(xìng)（溫度，蒸汽壓力，粘度等）。

　　建議性：隻有兩(liǎng)個活動部件(jiàn)：主動輪(lún)和動輪，隻有一(yī)個軸(zhóu)封。

　　堅固的重載結構(gòu)：低轉速。特大球軸承的外部(bù)軸承座可以承受軸向和徑向負載。

　　磨(mó)損率低：由于主(zhǔ)動輪和從動齒輪不成倍數關系。這(zhè)就意味着磨損可以被均勻的分散在每(měi)個齒輪(lún)上(shàng)。因為一個齒輪上的每一個齒輪接觸另一個齒輪上的每一個齒輪的次數一樣。

磨損調節系統(tǒng)：轉子邊緣的磨損可(kě)以通過調(diào)整(zhěng)轉子軸的位置來補(bǔ)償。這樣，即使(shǐ)在有(yǒu)相當大的磨損的情況下，也可以保證泵的穩定性(xìng)。

　　維護簡單，維護率低：不用移動泵，管道或泵(bèng)驅動裝置就可以(yǐ)進行檢查和調節。

　　互(hù)動性：标(biāo)準組件的設計可實現不同材料和特性零部件之間的替換。例如：有多種軸封系統可供選擇，還可以安裝帶夾套的外(wài)殼和(hé)軸蓋來代(dài)替标準部件。

　　端口位置可改(gǎi)變：泵殼可在軸承箱上旋轉以從不同位置處吸(xī)排液(yè)體。

　　預熱：加熱夾套或是與外殼鑄成(chéng)一體，或是安(ān)裝在端蓋上，或是安裝在填料壓蓋上。

　　旁路安全閥：旁路安全閥安裝在(zài)泵(bèng)上并且容易調(diào)節，在有些型号的泵上采取雙重安全閥并帶加熱夾套。●高粘度泵(bèng)的工作壓力的選(xuǎn)定

　　1, select the work pressure

　　高粘度泵額定的壓(yā)力是指泵連續工(gōng)作時的最高許用壓力，而其工作壓(yā)力則決定于外部負載，安裝和調試的(de)壽命與其工作壓力直接相關(guān)。對于(yú)不頻繁工作的齒輪泵，其工作壓(yā)力可取為泵的額定壓力，考慮到産品質量不同，最好(hǎo)将額定壓力降低20%～30%使用。對于經常工(gōng)作(zuò)于較高壓力下的齒輪(lún)泵，其工作(zuò)壓(yā)力應比泵的額定壓力低1～2個壓力(lì)級。石油化工設備常常是24小時連續(xù)運轉，這時泵的工作壓力應該取得比額定壓力低(dī)得多，且工作(zuò)轉速也(yě)應該低于額定轉速。如果(guǒ)高粘度齒輪泵的工作壓力(lì)調整過高，則會使齒輪(lún)泵在超負荷下(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.

●NYP高粘(zhān)度泵的安裝與試(shì)運(yùn)轉

　　Installation and commissioning

　　高粘度泵的支座(zuò)或法蘭與(yǔ)其驅(qū)動電機應采用共同(tóng)的安(ān)裝基礎，基礎(chǔ)、法蘭或(huò)支座均需(xū)具有足夠的剛度(dù)，以減(jiǎn)小齒輪泵運(yùn)轉時産生(shēng)的振動(dòng)和噪聲。電動機與齒輪泵須用彈性(xìng)聯軸器連接，同軸(zhóu)度小于(yú)0.1毫米，傾斜(xié)角不得大于1度。安裝聯軸器時不得用錘敲打，以免傷害齒輪泵的齒(chǐ)輪(lún)等零件。若(ruò)用(yòng)帶輪(lún)、鍊輪等驅動時應設(shè)托架支(zhī)承，以防主動(dòng)齒輪軸承受徑向力(lì)。緊固齒輪泵、電動機的(de)地腳螺釘時，螺釘受力應均勻，連接可靠。用手(shǒu)轉(zhuǎn)動聯軸器時，應感覺(jiào)到齒(chǐ)輪泵能夠輕松地轉(zhuǎn)動，沒(méi)有卡緊等異常現象(xiàng)出現，然後(hòu)才可以配管(guǎn)。高粘度齒輪泵的(de)吸油管道内徑應足夠大，并避免狹窄通(tōng)道或(huò)急劇拐彎、彎頭，去(qù)除不必要的閥門、附件，盡可能(néng)地降低泵的安裝高度，縮短(duǎn)吸油管道的長度，以減少(shǎo)壓力損失。管接頭等元件的密封要(yào)良好，以防(fáng)止空氣(qì)侵入，從而控制氣穴與氣蝕的(de)發生。在開始運轉前，往齒輪泵的殼體内灌(guàn)滿待輸送(sòng)的液體，便于安全動(dòng)。若環境溫(wēn)度低于冰點，應預先向泵内通入熱蒸汽，進行(háng)預熱(rè)處理，然後才可啟動齒輪泵。齒(chǐ)輪泵的旋(xuán)轉方(fāng)向要與進、出油(yóu)口相(xiàng)符。齒輪泵若是(shì)第一次運行，或長期(qī)閑置(zhì)後再使(shǐ)用(yòng)，最好在空載或小負荷情況(kuàng)下先跑(pǎo)合一小時左右。如果在跑合階段預先覺出異常溫升、洩漏、振(zhèn)動和噪聲時，應機檢查。高粘度(dù)泵的出口管路上還應當設置安全閥等保護裝置，這樣一旦(dàn)泵的出口通道發生堵塞，就可以打開(kāi)安全閥卸壓。對于需要(yào)正反轉的(de)高粘度齒(chǐ)輪泵，其進出口管路上均(jun1)需設置安(ān)全閥(fá)。High viscosity pump bearing or flange and its drive motor should use common installation basis, 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 than 0.1 mm, Angle shall not be greater than 1 degree.When installing coupling hammer shall not be used, in order to avoid damage gear and other parts of the gear pump.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.High viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp bend, bend, 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.Before starting operation, to gear pump casing filled with liquid, easy to safety.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.Direction of rotation of the gear pump, 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 the abnormal temperature rise, leakage, vibration and noise, should machine inspection.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.For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
