●高粘度泵(beng)概述High viscosity pump overview NYP型内(nei)環式高粘(zhān)度泵是一(yī)種容積式(shì)内轉子泵(beng)。這種類型(xing)的泵自吸(xī)性能強,适(shi)用于輸送(sòng)不含固體(ti)顆粒和纖(xian)💁維的粘稠(chou)液體💋,甚至(zhi)是半固體(ti)狀态的液(yè)體,最✍️高輸(shu)送粘度達(da)到3*105厘泊。具(jù)有體積小(xiao)、重量輕、脈(mo)動小、噪音(yīn)低、運轉平(píng)穩、壽命長(zhang)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(gai)型泵可廣(guang)泛用于石(shi)油、化工、顔(ya)料、化工、顔(yá)料、食品、肥(féi)皂、洗滌👈劑(ji)及制藥等(deng)行業。This type of pump can be widely used in petroleum, chemical, pigment, chemical, pigment, food, soap, detergent and pharmaceutical industries. ●高粘(zhan)度泵使用(yong)時注意事(shì)項Matters needing attention when using high viscosity pump 進、出口(kou)管路的管(guǎn)徑必須和(hé)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(jin)量減少彎(wan)頭,且彎頭(tou)角度不宜(yí)過小,進口(kou)管線不宜(yí)過長,以免(mian)影響自吸(xī)。 啟動前每(mei)個注油杯(bēi)都應家潤(run)滑油,且保(bǎo)證每天加(jia)油一次。 泵(beng)在工作前(qián)應該點動(dong)啟動電機(jī),觀察轉向(xiàng)是否和規(guī)定💔轉向⛹🏻♀️一(yī)緻。 開機後(hòu)觀察運轉(zhuǎn)是否正常(cháng),如有不正(zhèng)常噪音、特(te)殊♌振動或(huo)溫升過高(gāo)等情況,應(ying)停機檢查(cha)。 注意皮帶(dài)松緊是否(fǒu)恰當,每半(ban)年調整一(yi)次。 ●高粘度(dù)泵工作原(yuán)理: 高粘度(dù)泵是容積(jī)式内齧合(he)齒輪泵,主(zhǔ)動齒輪(外(wài)轉子)帶動(dong)被動齒輪(lún)(内轉子)旋(xuán)轉時,不斷(duan)産生封閉(bì)的空間,在(zài)吸油區齒(chǐ)輪逐漸脫(tuo)離齧合💃🏻而(ér)液體不㊙️斷(duàn)地充滿齒(chǐ)間并被帶(dai)到出油區(qū),齒輪在出(chū)油區進入(rù)齧合時液(ye)♌體被排出(chū)。兩個旋轉(zhuǎn)齒輪的❗共(gong)同作用,形(xíng)成一個穩(wen)定的體🎯積(jī)排量,沒有(you)脈動。由于(yú)泵是完全(quan)📱對稱的,泵(beng)可以反轉(zhuǎn),液流方向(xiàng)也随之🔴改(gǎi)變。但應注(zhu)🏃♂️意,泵的轉(zhuǎn)向可能受(shou)到密封或(huo)泵内其它(ta)結構的限(xiàn)制,用戶有(you)反轉要求(qiu)時應在訂(ding)貨時做出(chu)說明。 ●高粘(zhān)度泵優點(dian): 轉子泵的(de)軸向位置(zhì)可調,不需(xū)要拆泵。 泵(bèng)采用模塊(kuai)化設計,可(kě)根據不同(tong)的使用要(yào)求更換不(bu)💜同部件。可(kě)選夾層結(jié)構,以方便(bian)對泵加熱(rè)或冷卻👅,可(kě)以選擇📞是(shi)否帶安全(quan)閥,可以選(xuan)擇不同的(de)密封形式(shì),詳見密封(fēng)結構圖。泵(beng)的各個零(ling)件可以選(xuǎn)用不同的(de)材質以适(shì)應具體使(shi)用要求。 不(bú)同的使用(yong)條件,泵的(de)結構形式(shì)可能不同(tóng),具體應用(yong)請❌向廠家(jiā)或本公司(si)客戶代表(biao)咨詢。需要(yào)指出的🆚是(shi)泵的轉♊速(sù)愈高,泵的(de)磨損愈嚴(yan)重,液體中(zhong)如含有磨(mó)料物質,泵(beng)的🚶♀️材料應(ying)選用耐磨(mó)材質,在此(ci)種工況下(xia),泵的壓力(lì)和轉速❄️都(dou)應降低,高(gāo)溫條件下(xia),則應增加(jiā)泵的間隙(xi),并采用耐(nai)熱🔞材料 。
流(liú)動穩定:流(liú)量與齒輪(lun)轉速成正(zhèng)比,與壓力(lì)無關 流動(dong)平穩:沒有(you)脈動和壓(yā)力波峰,不(bu)會産生管(guan)道顫動。 多(duo)功能性:僅(jin)僅通過調(diao)整轉子軸(zhou)的位置,同(tong)一台泵既(jì)可以出來(lai)💰稀釋溶液(yè)又可以出(chu)來瀝青,糖(táng)漿,樹脂,聚(jù)合🌈物等高(gao)粘度液💃體(ti)。 可逆性:可(ke)以通過改(gǎi)變齒輪的(de)旋轉方向(xiàng)使液體反(fǎn)向流動,兩(liǎng)種方向都(dou)能充分發(fā)揮泵的性(xing)能 自吸性(xing):由泵産生(sheng)高真空,允(yǔn)許在最大(dà)自吸高度(du)實現㊙️快速(su)自💞吸,取決(jué)于泵送液(yè)體的物理(lǐ)特性(溫度(du),蒸汽壓力(li),粘度等)。 建(jiàn)議性:隻有(yǒu)兩個活動(dong)部件:主動(dòng)輪和動輪(lun),隻有一個(ge)軸封。 堅固(gu)的重載結(jie)構:低轉速(sù)。特大球軸(zhóu)承的外部(bù)軸承座可(ke)以承受🈲軸(zhóu)向和徑向(xiàng)負載。 磨損(sǔn)率低:由于(yu)主動輪和(hé)從動齒輪(lún)不成倍數(shù)關系。這就(jiù)意味着☔磨(mó)損可以被(bèi)均勻的分(fen)散在每個(ge)齒輪上。因(yīn)為一個齒(chi)輪上的每(měi)一個齒輪(lun)接觸另一(yi)個齒輪上(shàng)的每一個(ge)🌈齒輪的次(cì)數一樣。 磨(mo)損調節系(xì)統:轉子邊(bian)緣的磨損(sun)可以通過(guo)調整轉子(zǐ)軸的位置(zhì)來補償。這(zhe)樣,即使在(zai)有相當大(dà)的磨損的(de)情況下,也(yě)可以保證(zhèng)泵的穩定(ding)性。 維護簡(jian)單,維護率(lǜ)低:不用移(yi)動泵,管道(dào)或泵驅動(dòng)裝🏃♀️置🔱就可(kě)以進行檢(jian)查和調節(jie)。 互動性:标(biāo)準組件的(de)設計可實(shi)現不同材(cái)料和特性(xìng)零部件之(zhī)間的替換(huàn)。例如:有多(duo)種軸封系(xi)統可供選(xuǎn)擇,還可以(yi)安裝帶夾(jiá)套的外殼(ke)和軸蓋來(lái)代替标準(zhǔn)部件。 端口(kǒu)位置可改(gai)變:泵殼可(kě)在軸承箱(xiāng)上旋轉以(yǐ)從不同位(wèi)置處📧吸♋排(pái)液體。 預熱(rè):加熱夾套(tào)或是與外(wai)殼鑄成一(yi)體,或是安(ān)裝在端蓋(gai)上,或是🥵安(ān)裝在填料(liào)壓蓋上。 旁(pang)路安全閥(fa):旁路安全(quan)閥安裝在(zài)泵上并且(qiě)容易調節(jiē),在有些型(xing)号的泵上(shàng)采取雙重(zhòng)安全閥并(bìng)帶加熱夾(jia)套。 在開始(shǐ)運轉前,往(wǎng)齒輪泵的(de)殼體内灌(guan)滿待輸送(sòng)的液體,便(bian)于安全啟(qǐ)動。若環境(jing)溫🐉度低于(yú)冰點,應預(yu)先向泵内(nei)通入熱蒸(zheng)汽,進行😄預(yù)熱✨處理👄,然(ran)後才可啟(qi)動齒輪泵(bèng)。高粘度泵(beng)的旋轉方(fang)向要與進(jin)、出油口相(xiang)符。齒輪泵(bèng)若是第一(yī)次運行,或(huò)長期閑置(zhì)後再使用(yòng),最好在空(kōng)載或小負(fu)荷情況下(xià)先跑合一(yi)小時左右(you)。如果在跑(pǎo)合階段預(yu)先覺察出(chū)異常溫升(shēng)、洩漏、振動(dong)和噪聲時(shí)🌈,應停機檢(jiǎn)查。高粘度(dù)齒輪泵的(de)支座或法(fǎ)蘭與其驅(qu)動電機應(yīng)采用共同(tóng)的安裝💚基(jī)礎,基礎、法(fǎ)蘭或支座(zuo)均需具有(you)足夠的剛(gāng)度,以減小(xiǎo)齒輪泵運(yun)轉時産生(shēng)的振動和(hé)噪聲。電動(dong)機與齒輪(lun)泵須用彈(dàn)性聯軸器(qì)連接,同軸(zhóu)度小于0.1毫(hao)米,傾斜角(jiao)不得大于(yu)1度。安裝聯(lián)軸器時不(bú)得用錘敲(qiao)打,以免傷(shāng)害齒輪泵(beng)的齒輪等(deng)零件。若用(yòng)帶輪、鍊輪(lún)等驅動時(shí)應設托架(jia)支承,以防(fang)主動齒輪(lún)軸承受徑(jìng)向力。緊固(gù)齒輪泵、電(dian)動機的地(dì)腳螺釘時(shi),螺釘受力(lì)應均勻,連(lián)接可靠。用(yong)手轉動聯(lián)軸器時,應(ying)感覺到齒(chǐ)輪泵能夠(gou)輕松地轉(zhuan)動,沒有卡(ka)緊等異常(cháng)現象出現(xian),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(gāo)粘度齒輪(lun)泵的吸油(you)管道内徑(jìng)應足夠大(dà),并避免狹(xia)窄通道或(huo)急劇拐彎(wan)、減少⭐彎頭(tóu),去除不必(bi)要的閥門(men)、附件,盡可(kě)能地降低(dī)泵的安裝(zhuāng)高度,縮短(duan)吸油管道(dào)的長度,以(yǐ)減少壓力(li)㊙️損失。管接(jiē)頭等📐元件(jian)的密封要(yào)✊良好,以防(fang)止😘空氣侵(qin)入,從而控(kòng)制氣穴與(yu)氣✌️蝕的發(fa)生。止回閥(fa)與安全閥(fa)在齒輪泵(bèng)的輸出管(guǎn)路上最好(hao)安裝一個(gè)止回閥。這(zhe)樣在檢修(xiū)👉泵及輸出(chu)管㊙️道時,系(xì)統中的液(yè)體不會發(fa)生倒流。齒(chi)輪泵帶負(fu)荷停車時(shi),亦可防止(zhi)泵倒轉而(er)在其輸出(chū)管道内産(chǎn)㊙️生局部真(zhēn)空。應當注(zhù)意,出口止(zhǐ)回閥不能(neng)裝反或出(chu)現卡死現(xiàn)象。高粘度(dù)泵的出口(kou)管路上還(hai)應當設置(zhì)安全閥等(děng)保護裝💃🏻置(zhi),這樣一旦(dan)泵的出口(kǒu)通道發生(sheng)堵塞,就可(ke)以打😘開安(an)全閥卸壓(ya)。安全💔閥可(ke)以與泵體(tǐ)或泵蓋🥵鑄(zhu)成一體,也(ye)可以單獨(du)裝配。對于(yu)需要正反(fan)轉的高粘(zhān)度齒輪泵(beng),其進出口(kou)管路上均(jun1)需設置安(ān)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.
