●高粘度泵概述High viscosity pump overview NYP型内環式高粘度泵是一種容積式(shì)内轉子(zǐ)泵。這種類型的泵自吸性能強,适用于輸送不含固體顆(kē)粒和纖維的粘稠液體,甚(shèn)至是半固體(tǐ)狀态(tài)的液體,最高輸送粘度達到3*105厘泊。具(jù)有體積小、重量輕(qīng)、脈動小、噪音低、運轉平穩、壽命長等優點。NYP high viscosity of the inner ring type pump is a kind of positive displacement rotor pump.This type of pump self-priming performance is strong, is suitable for conveying viscous liquid containing no solid particles and fibers, even half solid state of liquid, conveying viscosity up to 3 * 105 centipoise.With small volume, light weight, small ripple, low noise, smooth operation, long service life, etc. 該(gāi)型泵可廣泛用于石油、化工(gōng)、顔料、化工、顔料、食品、肥皂、洗(xǐ)滌劑(jì)及制藥等行業。This type of pump can be widely used in petroleum, chemical, pigment, chemical, pigment, food, soap, detergent and pharmaceutical industries. ●高粘度泵使用(yòng)時注意事項Matters needing attention when using high viscosity pump 進(jìn)、出口管路的管(guǎn)徑必須和泵保持一(yī)緻;The diameters of inlet and outlet piping must be consistent with pump; 設計管(guǎn)路時應盡量減少彎頭,且彎頭(tóu)角度不宜過小,進口管線不宜過長,以免(miǎn)影響自吸(xī)。 啟動前每個注油杯都應家潤滑油,且保(bǎo)證每天加(jiā)油一次。 泵(bèng)在工作前(qián)應該點動啟動電機,觀察轉向(xiàng)是否和規定轉向一緻。 開機(jī)後觀察運轉是否正常(cháng),如有(yǒu)不正常噪音、特殊振動或溫(wēn)升過高(gāo)等情況,應停機檢查。 注意皮帶松緊是否恰當(dāng),每半年調整一次。 ●高粘度泵工作原(yuán)理: 高(gāo)粘度泵是容積式内(nèi)齧合齒輪泵,主(zhǔ)動齒輪(lún)(外轉子)帶動被動齒輪(lún)(内轉子)旋(xuán)轉時,不(bú)斷産生封閉的空(kōng)間,在吸油區齒輪(lún)逐漸脫(tuō)離齧合而液體不斷地充滿(mǎn)齒間并被帶到出(chū)油區,齒輪在出油區進入齧合時液(yè)體被排出。兩個旋(xuán)轉齒輪的共(gòng)同作(zuò)用,形成一個穩(wěn)定(dìng)的體積排量,沒有(yǒu)脈動。由于泵是完全對稱(chēng)的,泵可以反轉,液流方向也(yě)随之改(gǎi)變。但應注意,泵的轉向可能受到密封或泵内(nèi)其它結構的限(xiàn)制(zhì),用戶(hù)有反轉要求時應在訂(dìng)貨時做出說明。 ●高粘度泵(bèng)優點: 轉子泵的軸向位置可調,不需(xū)要拆泵。 泵采用模塊化設計,可(kě)根據不同的使用要求更換不(bú)同部件。可選夾層結構(gòu),以方便對泵加熱或冷(lěng)卻,可以選擇是(shì)否(fǒu)帶安全閥,可以選擇(zé)不同的密封形式,詳見(jiàn)密封結構圖。泵(bèng)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(shǐ)用條件,泵的結構形式可能不同(tóng),具體應用(yòng)請向廠家或(huò)本公司客戶(hù)代表咨詢。需要指出的是泵的轉速愈高,泵的磨損愈嚴重,液體中如含有(yǒu)磨(mó)料物質,泵的材料應(yīng)選用耐磨材質,在此種工況下,泵的壓力(lì)和轉速都應降(jiàng)低,高溫條件下,則應(yīng)增加(jiā)泵的間隙,并采用耐熱材料(liào) 。 流動穩定:流量與齒輪轉速成正比,與壓力無關 流動平穩:沒有脈動和壓(yā)力波(bō)峰,不會産生管道顫(chàn)動。 多功能性:僅(jǐn)僅通過調整轉子軸的位置,同一台(tái)泵既可以出來稀釋溶液(yè)又可以出來瀝(lì)青,糖漿,樹脂(zhī),聚合物等高粘度(dù)液體。 可逆性:可(kě)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(bèng)的性能 自吸性:由泵産生高真空,允許在最大自吸高度實現快速自吸,取決(jué)于泵送液體的物理特性(溫度,蒸汽壓力(lì),粘度(dù)等)。 建議性:隻有兩(liǎng)個活動部件(jiàn):主動輪和動輪,隻有一個軸封。 堅固的重載結構:低轉速。特大球軸承的外部軸承座可以承受軸(zhóu)向和徑向負載。 磨損率低:由于主(zhǔ)動輪和從動齒輪不成倍數關系。這就意味着磨損可以被均勻的分散在每(měi)個齒輪上。因(yīn)為一個齒輪上的每一個齒輪接觸另一(yī)個(gè)齒輪上的每一個齒輪的次數一(yī)樣。 磨損調節系統:轉子邊緣的(de)磨損可以通過(guò)調整轉子軸的位置(zhì)來補償。這樣,即使在有相當大的磨(mó)損的情況下,也可(kě)以保證泵的穩定性。 維護簡單,維護(hù)率低:不用移動泵,管道或泵驅動裝置就可以進行檢(jiǎn)查和調節。 互動性:标(biāo)準組件的設計可實現不(bú)同材料和(hé)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(yǐ)安裝(zhuāng)帶夾套的外殼和軸蓋來代替标準部件。 端口位置(zhì)可改(gǎi)變:泵殼可在軸承箱(xiāng)上旋轉以從不同位置處吸排液體。 預熱:加熱夾套或是與外殼鑄成一(yī)體,或是安裝(zhuāng)在端蓋(gài)上,或是安(ān)裝在填料壓蓋(gài)上。 旁路安全閥(fá):旁路安全閥安(ān)裝(zhuāng)在泵上并且容易調節,在有些型号的(de)泵上采取雙重(zhòng)安全閥并帶加熱夾(jiá)套。 在開始(shǐ)運轉前,往(wǎng)齒輪泵的(de)殼體内灌(guàn)滿待輸送的液體,便于安全啟(qǐ)動。若環境溫度低于冰點,應(yīng)預(yù)先向泵内通入熱蒸汽,進行預熱處理,然後才可啟動齒(chǐ)輪泵。高粘度泵的旋轉方向要與進(jìn)、出油口相符。齒輪泵若是第一次運行,或長期閑置後再使用,最好在空載或小負荷情況下(xià)先跑合一小時左右。如果在跑(pǎo)合階段預先覺察出(chū)異常溫升(shēng)、洩漏(lòu)、振動和噪聲時,應停機檢查。高粘度齒輪泵的支座或法蘭與其驅動電機應采用共同的安裝基礎,基礎、法蘭或支座均需具有足夠的剛(gāng)度(dù),以減小齒輪泵運(yùn)轉時(shí)産生(shēng)的振動和噪聲。電動機與齒輪泵須用彈性聯(lián)軸器連接,同軸度小(xiǎo)于0.1毫(háo)米,傾斜角不(bú)得(dé)大于1度。安裝聯軸器時不(bú)得用錘敲打,以免傷(shāng)害齒輪泵的齒輪等零(líng)件。若用帶輪、鍊輪(lún)等驅動時應設托架支承,以防主動齒輪軸承受徑向(xiàng)力。緊固齒輪泵、電(diàn)動機的地(dì)腳螺釘時,螺釘受力應均(jun1)勻,連接可靠。用手轉(zhuǎn)動聯軸器時,應(yīng)感覺到齒(chǐ)輪泵能夠輕松地轉(zhuǎn)動,沒(méi)有卡緊等異常現象出現,然後才可(kě)以配管。High viscosity pump before starting work, to gear pump casing filled with liquid, facilitate safe launch.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.The direction of rotation of the pump with high viscosity, 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 detect abnormal temperature rise, leakage, vibration and noise, should stop check.High viscosity gear pump bearing or flange should adopt a common drive motor installationFoundation, 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 of the gear pump gearAnd other parts.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. 高粘度(dù)齒輪泵的吸油管道内徑應(yīng)足夠大,并(bìng)避免狹窄通道或(huò)急劇拐彎、減少彎(wān)頭(tóu),去除不必要的閥門、附件,盡可能地降低泵的安裝(zhuāng)高度,縮短吸油管道的長度,以減少壓力損失。管接(jiē)頭等元件的密封要良好,以防止空氣(qì)侵入,從而控制氣穴與氣蝕的發(fā)生。止回閥與安全閥在齒輪泵(bèng)的輸出管路上最好安裝一個止回閥。這樣在(zài)檢修(xiū)泵及輸出(chū)管道時,系統中的液體不會發生倒流。齒(chǐ)輪泵帶負荷停車時,亦可防止(zhǐ)泵倒轉而在其輸(shū)出管道内産生局(jú)部真空。應當注意(yì),出口止回閥不能(néng)裝反或出現卡死現象。高粘度泵的出口(kǒu)管路上還應當(dāng)設置安全閥等(děng)保護裝置,這樣一(yī)旦泵(bèng)的出口(kǒu)通道發生堵塞,就可(kě)以打開安全閥卸壓。安全閥可以與泵體或泵蓋鑄成一體,也可以單獨裝配。對于(yú)需要正反轉的高粘度齒輪泵(bèng),其進出口管路(lù)上均(jun1)需設置安全閥。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.
