●高粘度泵概述(shu)High viscosity pump overview NYP型内環式高粘(zhān)度泵是一種容(rong)積式内轉子泵(beng)。這種類型的泵(beng)自吸性能強,适(shì)用于輸送不含(hán)固體顆粒和纖(xian)💔維的粘稠⛱️液體(ti)🔆,甚至是半固體(ti)狀态的液體,最(zuì)🐪高輸送粘度達(da)到3*105厘泊。具有體(ti)積小、重量輕、脈(mò)動小、噪音低、運(yùn)轉平穩🔅、壽命長(zhǎng)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. 該型泵(bèng)可廣泛用于石(shi)油、化工、顔料、化(hua)工、顔料、食品、肥(fei)皂、洗♉滌劑及制(zhì)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(zhān)度泵使用時注(zhu)意事項Matters needing attention when using high viscosity pump 進、出口(kou)管路的管徑必(bì)須和泵保持一(yi)緻;The diameters of inlet and outlet piping must be consistent with pump; 設計管路時(shí)應盡量減少彎(wan)頭,且彎頭角度(dù)不宜過小,進✏️口(kou)✍️管線不宜過長(zhang),以免影響自吸(xī)。 啟動前每個注(zhu)油杯都應家潤(rùn)滑油,且保證每(měi)天加油一次。 泵(beng)在工作前應該(gāi)點動啟動電機(ji),觀察轉向是否(fǒu)和規⁉️定轉♍向一(yī)緻。 開機後觀察(cha)運轉是否正常(cháng),如有不正常噪(zào)音、特殊振🏃♂️動或(huo)溫🔱升過高等情(qíng)況,應停機檢查(chá)。 注意皮帶松緊(jin)是否恰當,每半(bàn)年調整一次。 ●高(gāo)粘度泵工作原(yuán)理: 高粘度泵是(shi)容積式内齧合(hé)齒輪泵,主動齒(chi)輪(外轉子)帶動(dong)被動齒輪(内轉(zhuǎn)子)旋轉時,不⭐斷(duan)産生封閉💃🏻的空(kong)間,在吸油區齒(chi)輪逐漸脫離齧(niè)合而液體不斷(duàn)地充滿齒間并(bing)被帶到出油區(qu),齒輪在🏃🏻♂️出油區(qū)進入齧合時液(ye)體被排出。兩個(gè)旋轉齒輪的♉共(gong)同作用,形成一(yī)個穩定的體積(ji)排量,沒有脈動(dong)。由♻️于泵是完全(quan)對稱的,泵可💯以(yi)反轉,液流方向(xiang)也随之改變。但(dan)應注意💋,泵的轉(zhuǎn)向可能🎯受到密(mi)封或泵内其它(ta)結構的限制,用(yong)戶有反✨轉要求(qiu)時🈲應在訂貨時(shi)做出說明。 ●高粘(zhan)度泵優點: 轉子(zǐ)泵的軸向位置(zhì)可調,不需要拆(chāi)泵。 泵采用模塊(kuài)化設計,可根據(jù)不同的使用要(yào)求更換不同部(bu)件♌。可選夾層結(jié)構,以方便對泵(bèng)加熱或冷卻,可(ke)以🛀🏻選擇是否🌈帶(dài)安全閥,可以選(xuan)擇不同的密封(feng)形🙇🏻式,詳見密封(feng)結構圖。泵的各(ge)個零件可以選(xuǎn)用不同🏒的材質(zhi)以🈲适應具體使(shi)用要求。 不同的(de)使用條件,泵的(de)結構形式可能(neng)不同,具體應用(yòng)請向廠家或本(běn)公司客戶代表(biǎo)咨詢。需要指出(chū)的是泵⛹🏻♀️的轉速(sù)愈🔴高,泵的磨損(sǔn)愈嚴重,液體中(zhong)如含有磨料物(wù)質,泵的材料應(ying)選用耐👉磨材質(zhi),在此種工況⭐下(xià),泵的壓力和轉(zhuan)速都應降低,高(gāo)溫條件下,則應(yīng)增🌈加泵的間隙(xì)⭕,并采用耐熱🙇🏻材(cái)料 。
流動穩定:流(liú)量與齒輪轉速(sù)成正比,與壓力(lì)無關 流動平穩(wen):沒有脈動和壓(yā)力波峰,不會産(chǎn)生管道顫動。 多(duō)功能性:僅僅通(tong)過調整轉子軸(zhóu)的位置,同一台(tái)泵既可以出來(lái)稀釋溶液又可(ke)以出來瀝青,糖(tang)漿,樹脂,聚合物(wu)等高粘度液體(ti)。 可逆性:可以通(tōng)過改變齒輪的(de)旋轉方向使液(ye)體反🌈向流👈動👉,兩(liǎng)⭐種方向都能充(chōng)分發揮泵的性(xing)能 自吸性:由泵(bèng)産生高真空,允(yun)許在最大自吸(xī)高度實🤟現快🔴速(su)自吸,取決于泵(beng)送液體的物理(li)特性(溫度,蒸汽(qi)壓力,粘度等)。 建(jian)議性:隻有兩個(ge)活動部件:主動(dong)輪和動輪,隻有(you)一💚個軸封。 堅固(gù)的重載結構:低(di)轉速。特大球軸(zhóu)承的外部軸承(cheng)😘座可以🔞承受軸(zhóu)向和徑向負載(zai)。 磨損率低:由于(yú)主動輪和從動(dong)齒輪不成倍數(shu)關系。這🙇♀️就意味(wei)着磨損可以被(bèi)均勻的分散在(zài)每個齒輪上。因(yīn)為一個齒輪上(shàng)🏃♂️的每一個齒輪(lún)接觸另一個齒(chǐ)輪上的每一個(gè)齒輪的🈲次數一(yī)樣。 磨損調節系(xì)統:轉子邊緣的(de)磨損可以通過(guò)調整轉子軸的(de)位❤️置🏃來補償。這(zhè)樣,即使在有相(xiang)當大的磨損的(de)情況下,也可以(yi)保證泵㊙️的穩定(dìng)性。 維護簡單,維(wei)護率低:不用移(yí)動泵,管道或泵(bèng)驅動裝置就可(ke)以進行檢查和(hé)調節。 互動性:标(biāo)準組件的設計(ji)可實現不同材(cái)料和特性零部(bù)件之間的替換(huàn)。例如:有多種軸(zhou)封系統可供選(xuan)🔴擇,還可以安裝(zhuang)⛷️帶夾套的外殼(ké)和軸蓋來代替(ti)标準部件。 端口(kǒu)位置可改變:泵(bèng)殼可在軸承箱(xiang)上旋轉以從不(bú)同位置㊙️處吸排(pái)液體。 預熱:加熱(rè)夾套或是與外(wài)殼鑄成一體,或(huo)是安裝在端蓋(gai)上😄,或是安裝在(zai)填料壓蓋上。 旁(pang)路安全閥:旁路(lù)安全閥安裝在(zài)泵上并且容易(yì)調節,在🎯有些型(xing)号的泵上采取(qǔ)雙重安全閥并(bing)帶加熱夾套。 在開始運轉(zhuǎn)前,往齒輪泵的(de)殼體内灌滿待(dai)輸送的液體,便(bian)于安全啟動。若(ruò)環境溫🏃♂️度低于(yú)冰點,應預先向(xiàng)泵内通入熱蒸(zheng)汽,進行預熱處(chu)理,然後才可啟(qi)動齒輪泵。高粘(zhān)度泵的旋轉方(fang)向要與進、出油(yóu)口相符。齒輪泵(bèng)若是第一次運(yùn)行,或長期閑置(zhì)後再使用,最好(hao)在空載或小💯負(fù)💃荷情況下先跑(pǎo)合一小時左右(yòu)。如果在跑合階(jiē)段預先覺察出(chū)異常溫升、洩漏(lou)、振動和噪聲時(shi)🛀,應停機檢查。高(gāo)♍粘度齒輪泵的(de)支座或法蘭與(yǔ)其驅動電機應(ying)采用共同的安(an)裝基礎,基🧑🏽🤝🧑🏻礎、法(fǎ)蘭或支座均需(xū)具有足夠的剛(gang)度,以減小齒輪(lun)泵運轉時産生(shēng)的振動和噪聲(shēng)。電動機與齒輪(lún)泵須用彈性聯(lián)軸器連接,同軸(zhóu)度小于0.1毫米,傾(qīng)斜角不得大于(yú)1度。安裝聯軸器(qi)時不得用錘敲(qiao)打,以免傷害齒(chi)輪泵的齒輪等(deng)零件。若用帶輪(lun)、鍊輪等驅動時(shi)應設托架支♊承(chéng)💁,以⭕防主動齒輪(lún)軸承受徑向力(lì)。緊固齒輪泵、電(diàn)動機的地腳螺(luo)釘時,螺釘受力(lì)應均勻,連接可(ke)靠。用🐇手轉動聯(lian)軸器時,應感覺(jiao)到齒輪泵能夠(gòu)輕松地轉動,沒(mei)有卡緊等異常(cháng)現象出現,然後(hou)才可以配🌐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(gao)粘度齒輪泵的(de)吸油管道内徑(jing)應足夠大,并避(bi)免狹窄通道或(huò)急劇🏒拐彎、減少(shǎo)彎頭,去除不必(bi)要的閥門、附件(jian),盡可能地降✔️低(di)泵的安裝高度(dù),縮短吸油管道(dao)的長度,以減少(shǎo)壓力損失。管接(jiē)頭等元件的密(mi)封要良好,以防(fang)止空氣侵入,從(cong)而控制氣穴與(yu)氣🙇♀️蝕的發生🙇🏻。止(zhǐ)回閥與安全閥(fa)在齒輪泵的輸(shu)出管路上最好(hǎo)安裝一個止回(huí)閥。這樣在檢修(xiu)泵及輸出☎️管道(dao)時,系統中的液(ye)體不會發生倒(dǎo)流。齒輪泵帶負(fu)荷停車時,亦可(ke)防止泵倒轉而(er)在其輸出管道(dao)内産生局部真(zhen)空。應當注意,出(chu)口止回閥不能(neng)裝反或出現卡(kǎ)🌈死現象。高粘度(du)泵的出口管路(lù)上還應當設置(zhì)安全閥等保護(hù)裝🤟置,這樣一旦(dàn)泵的出口通道(dào)發生堵塞,就可(kě)以打開安全閥(fá)卸壓。安全閥可(kě)以與泵體或泵(bèng)蓋🤩鑄成一體,也(ye)可以單獨裝配(pei)。對于需要‼️正反(fǎn)轉的高粘度齒(chi)輪泵,其進出口(kǒu)管路上均需設(she)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.
