●高(gāo)粘度泵概述High viscosity pump overview NYP型内(nèi)環式高粘度泵是(shì)一種容積式内轉(zhuǎn)子泵。這種類型的(de)泵自吸性能強,适(shi)用于輸送不含固(gù)體顆粒和纖🍉維的(de)粘稠液體☁️,甚至👈是(shì)半固體狀态的液(ye)體,最高輸送😍粘度(dù)達到3*105厘泊。具有體(tǐ)積小、重量輕、脈動(dong)小、噪音低、運轉平(ping)穩、壽♍命🌈長等⚽優點(diǎn)。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. 該型泵可廣泛用(yòng)于石油、化工、顔料(liào)、化工、顔料、食品、肥(féi)皂、洗滌劑及制藥(yao)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(beng)使用時注意事項(xiang)Matters needing attention when using high viscosity pump 進、出口管路的管(guǎn)徑必須和泵保持(chí)一緻;The diameters of inlet and outlet piping must be consistent with pump; 設計管路時(shi)應盡量減少彎頭(tóu),且彎頭角度不宜(yí)過小,進口管線㊙️不(bu)宜過長,以免影響(xiǎng)自吸。 啟動前每個(ge)注油杯都應家潤(run)滑油,且保證每天(tiān)加💘油一次。 泵在工(gōng)作前應該點動啟(qi)動電機,觀察轉向(xiàng)是否和規㊙️定轉向(xiang)一緻。 開機後觀察(chá)運轉是否正常,如(ru)有不正常噪音、特(te)殊振動或🌈溫升過(guò)高等情況,應停機(jī)檢查。 注意皮帶松(song)緊是否恰當,每半(bàn)年調整一次。 ●高粘(zhan)度泵工作原理: 高(gao)粘度泵是容積式(shì)内齧合齒輪泵,主(zhǔ)動齒輪(外轉子)帶(dài)動被動齒輪(内轉(zhuan)子)旋轉時,不斷産(chan)生🍓封♌閉的空間,在(zai)吸油區齒輪逐漸(jiàn)脫離齧合而液體(ti)不斷地充滿齒間(jiān)📐并被帶到出油區(qu),齒輪在出油區進(jin)入齧㊙️合時液🐇體被(bei)排出。兩個旋轉齒(chǐ)輪的共同作用,形(xíng)成一個穩定的體(tǐ)🐪積排量,沒有脈動(dòng)。由于泵是完全對(dui)稱的,泵可以反轉(zhuan),液流方向也随之(zhī)改變。但應注意,泵(bèng)的轉向可能💚受到(dao)密封或泵内其它(ta)結構的限制,用戶(hu)有反轉要求時⛱️應(yīng)在訂貨時做出說(shuō)明。 ●高粘度泵優點(dian): 轉子泵的軸向位(wèi)置可調,不需要拆(chāi)泵。 泵采用模塊化(hua)設計,可根據不同(tong)的使用要求更換(huan)不同部件。可✔️選夾(jiá)層結構,以方便對(duì)泵加熱或冷卻,可(kě)以選擇是否帶安(an)全閥,可以選擇不(bu)同的密封形式,詳(xiang)見密封結構圖。泵(beng)的各個零件可以(yǐ)選用不同的材質(zhi)以适應具體🏃🏻使用(yong)要求。 不同的使用(yong)條件,泵的結構形(xíng)式可能不同,具體(ti)應用請向廠家或(huo)本公司客戶代表(biǎo)咨詢。需要指出的(de)是泵📱的轉速愈高(gāo),泵的磨損愈嚴重(zhong),液體中如含有磨(mo)料物🌐質,泵的材料(liao)應選用耐磨材質(zhì),在此種工況下,泵(beng)的壓力和轉速💰都(dou)應降低,高溫條件(jiàn)下,則應增☔加泵的(de)間隙,并采用耐熱(rè)材料 。
流動穩定:流(liu)量與齒輪轉速成(cheng)正比,與壓力無關(guān) 流動平穩:沒有脈(mò)動和壓力波峰,不(bú)會産生管道顫動(dòng)。 多功能性:僅僅通(tong)過調整轉子軸的(de)位置,同一台泵既(jì)可以出來稀釋溶(rong)液又可以出來瀝(li)青,糖漿,樹脂,聚合(hé)物等高粘度液♌體(tǐ)。 可逆性:可以通過(guò)改變齒輪的旋轉(zhuǎn)方向使液體反向(xiang)流動,兩種方向都(dōu)能充分發揮泵的(de)性能 自吸性:由泵(bèng)産生高真空,允許(xu)在最大自吸高度(dù)實現快速自吸,取(qu)決于泵送液體的(de)物理特性(溫度,蒸(zhēng)💘汽壓⭐力,粘度等)。 建(jian)議性:隻有兩個活(huo)動部件:主動輪和(hé)動輪,隻有一個📱軸(zhou)⭐封。 堅固的重載結(jié)構:低轉速。特大球(qiú)軸承的外部軸承(cheng)座可以承受軸向(xiàng)和徑向負載。 磨損(sun)率低:由于主動輪(lún)和從動齒輪不成(cheng)倍數關系。這😍就意(yì)味❌着磨損可以被(bèi)均勻的分散在每(měi)個齒輪🔴上。因為一(yī)個齒輪上♋的每一(yi)個齒輪接觸另一(yi)個齒輪上的每一(yi)個齒輪的次數一(yī)樣。 磨損調節系統(tǒng):轉子邊緣的磨損(sun)可以通過調整轉(zhuan)子軸的位置來補(bu)償。這樣,即使在有(you)相當大的磨損🎯的(de)情況下🧑🏽🤝🧑🏻,也可以保(bao)🔞證泵的穩定性。 維(wéi)護簡單,維護率低(di):不用移動泵,管道(dào)或泵驅動裝置就(jiu)可以進行檢查和(hé)調節。 互動性:标準(zhǔn)組件的設計可實(shí)現不同材料和特(tè)性零部件🔱之⭐間🔞的(de)替換。例如:有多種(zhǒng)軸封系統可供選(xuǎn)擇,還可以安裝🔱帶(dai)夾套的外殼和軸(zhóu)蓋來代替标準部(bu)件。 端口位置可改(gai)變:泵殼可在軸承(cheng)箱上旋轉以從不(bú)🐆同位置💃處吸🌐排液(ye)體。 預熱:加熱夾套(tào)或是與外殼鑄成(chéng)一體,或是安裝在(zài)㊙️端🏃蓋上,或是安裝(zhuāng)在填料壓蓋上。 旁(páng)路安全閥:旁路安(an)全閥安裝在泵上(shàng)并且容易調🈲節💯,在(zài)🚩有🥵些型号的泵上(shàng)采取雙重安全閥(fá)并帶加熱夾套。 在開始運轉前,往(wǎng)齒輪泵的殼體内(nei)灌滿待輸送的液(yè)體,便于安全啟動(dong)。若環境溫度低于(yú)⛹🏻♀️冰點,應預先向泵(beng)内通入熱蒸汽,進(jin)行預熱處理,然後(hou)才可☀️啟動齒輪泵(beng)。高粘度泵的旋轉(zhuan)方向要與進、出油(you)口相符。齒輪泵若(ruo)是第一次運行,或(huo)長期閑置後再使(shi)用,最好在空載或(huò)小負荷情況下先(xian)跑合一小時左右(yòu)。如果在跑💰合階段(duàn)預先覺察出異常(chang)溫升、洩漏、振動和(he)噪聲時🧑🏾🤝🧑🏼,應停機‼️檢(jiǎn)查。高粘度齒輪泵(bèng)的支座或法蘭與(yu)其驅動電機應采(cai)用共同的安裝👣基(ji)礎,基礎、法👉蘭或支(zhi)座均需具有足夠(gòu)的剛度,以減小齒(chi)輪泵運轉時産生(shēng)的振動和噪聲。電(diàn)動機與齒輪泵須(xu)用彈性聯軸器連(lián)接,同軸度小于0.1毫(hao)米,傾斜角不得大(da)于1度。安裝聯軸器(qì)時不得用錘敲打(da),以免傷害齒輪泵(bèng)的齒輪等零件。若(ruò)用帶輪、鍊輪等驅(qū)動時應設托架支(zhi)承,以🌍防主動齒輪(lun)軸承受徑向力。緊(jin)固齒輪泵、電動機(jī)的地腳螺釘時,螺(luó)釘受力應均勻,連(lian)接可靠。用手轉動(dong)聯軸器時,應感覺(jiao)到齒輪泵能夠輕(qing)松地轉動,沒有卡(ka)緊等異常現象出(chu)現,然後才可以配(pèi)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. 高粘度齒輪泵(beng)的吸油管道内徑(jing)應足夠大,并避免(mian)狹窄通道或急劇(ju)拐彎、減🌈少彎頭,去(qu)除不必要的閥門(mén)、附件,盡可能地降(jiàng)低泵的安🐉裝高度(dù),縮🛀🏻短吸油管道的(de)長度,以減少壓力(li)損失。管接頭等🏃🏻♂️元(yuán)件的密封要良好(hǎo),以防止空氣侵入(ru),從而控制氣穴與(yǔ)氣蝕的發生。止回(huí)閥與安全閥在齒(chi)輪泵的輸出管路(lu)上最好安裝一個(gè)止回閥。這樣在檢(jian)修泵及輸出🈚管道(dào)時,系統中的液體(ti)不會發生倒流。齒(chǐ)輪泵帶負荷停車(chē)時,亦可防止泵倒(dao)轉而在其輸出管(guan)道内産生局部真(zhēn)空。應當注意,出口(kou)止回閥不能裝反(fǎn)或出✔️現卡死現象(xiàng)。高粘度泵的出口(kǒu)管路上還應當設(shè)置安全閥等保護(hu)裝置,這樣一旦泵(bèng)的出口通道發生(shēng)堵塞,就可以打開(kāi)安全閥卸壓。安全(quan)閥可以與㊙️泵體或(huo)泵蓋鑄成一體,也(yě)🍓可以單獨裝配。對(dui)于需要正反轉的(de)高粘度齒輪泵,其(qi)進出口管路上均(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.
