●高粘度(dù)泵概述(shu)High viscosity pump overview NYP型内環(huán)式高粘(zhan)度泵是(shì)一種容(róng)積式内(nei)轉子泵(beng)。這種類(lei)型的泵(beng)自吸性(xìng)能強,适(shì)用于輸(shu)送不含(hán)固體顆(kē)粒和纖(xian)維的粘(zhan)稠液體(ti),甚至是(shi)半固體(ti)狀态的(de)液體,最(zui)高輸送(song)粘度達(da)到3*105厘泊(bó)。具有體(tǐ)積小、重(zhong)量輕、脈(mò)動小、噪(zao)音低、運(yùn)轉平穩(wěn)、壽命🔴長(zhang)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(beng)可廣泛(fàn)用于石(shi)油、化工(gōng)、顔料、化(hua)工、顔料(liào)、食品、肥(fei)皂、洗滌(dí)🧑🏽🤝🧑🏻劑及制(zhi)藥等行(hang)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(shǐ)用時注(zhu)意事項(xiàng)Matters needing attention when using high viscosity pump 進、出口(kǒu)管路的(de)管徑必(bi)須和泵(bèng)保持一(yī)緻;The diameters of inlet and outlet piping must be consistent with pump; 設計(ji)管路時(shí)應盡量(liang)減少彎(wān)頭,且彎(wan)頭角度(du)不宜過(guo)🔞小,進口(kǒu)管線不(bu)宜過長(zhang),以免影(ying)響自吸(xī)。 啟動前(qian)每個注(zhu)油杯都(dōu)應家潤(rùn)滑油,且(qie)保證每(mei)天加油(yóu)㊙️一次。 泵(bèng)在工作(zuò)前應該(gai)點動啟(qi)動電機(jī),觀察轉(zhuan)向是否(fou)和規⭐定(ding)轉🙇🏻向一(yi)緻。 開機(ji)後觀察(chá)運轉是(shi)否正常(cháng),如有不(bu)正常噪(zào)音、特殊(shu)振動或(huò)溫升過(guò)高等情(qíng)況,應停(ting)機檢查(chá)。 注意皮(pi)帶松緊(jin)是否恰(qià)當,每半(ban)年調整(zheng)一次。 ●高(gāo)粘度泵(beng)工作原(yuán)理: 高粘(zhān)度泵是(shi)容積式(shi)内齧合(he)齒輪泵(beng),主動齒(chǐ)輪(外轉(zhuan)子)帶動(dòng)被動齒(chi)輪(内轉(zhuǎn)子)旋轉(zhuan)時,不斷(duàn)産🔞生封(fēng)閉的空(kong)間,在吸(xī)油區齒(chǐ)輪逐漸(jian)脫離齧(niè)合而液(ye)體不斷(duàn)地🐇充滿(mǎn)齒間⛱️并(bìng)被帶到(dao)出油區(qū),齒輪在(zài)出油區(qū)進入齧(niè)合時液(yè)體被排(pái)出。兩個(gè)旋轉齒(chǐ)輪的共(gong)同作用(yòng),形成一(yi)個穩定(dìng)的體積(jī)排量,沒(méi)有脈動(dong)。由于泵(bèng)是完全(quan)對稱的(de),泵可以(yǐ)反轉,液(yè)流方向(xiang)也随之(zhī)🛀🏻改變。但(dàn)應注意(yi),泵的轉(zhuǎn)向可能(neng)受到密(mi)封或泵(beng)内其它(ta)結構的(de)限制,用(yòng)戶有反(fan)轉要求(qiú)時應在(zài)訂貨時(shi)做出說(shuō)明。 ●高粘(zhān)度泵優(you)點: 轉子(zǐ)泵的軸(zhóu)向位置(zhì)可調,不(bu)需要拆(chāi)泵。 泵采(cǎi)用模塊(kuai)化設計(jì),可根據(jù)不同的(de)使用要(yao)求更換(huàn)不同❗部(bu)件。可選(xuan)夾層結(jié)構,以方(fang)便對泵(beng)加熱或(huò)冷卻💘,可(ke)以🔅選擇(ze)是否帶(dai)安全閥(fá)☁️,可以選(xuǎn)擇不同(tóng)的密封(feng)形式,詳(xiang)見㊙️密封(feng)結構圖(tú)。泵的各(gè)個零件(jian)可以選(xuǎn)用不同(tóng)的材質(zhi)以适應(ying)具體使(shi)用要求(qiú)。 不同的(de)使用條(tiao)件,泵的(de)結構形(xing)式可能(néng)不同,具(ju)體應用(yòng)請🧑🏽🤝🧑🏻向廠(chǎng)家💚或本(ben)公司客(kè)戶代表(biao)咨詢。需(xū)要指出(chū)的是泵(bèng)的轉速(sù)愈高,泵(beng)的磨損(sun)愈嚴重(zhong),液體中(zhōng)如含有(yǒu)磨料物(wu)質,泵的(de)材料應(yīng)❗選用耐(nai)磨材質(zhi),在此種(zhǒng)工況下(xià),泵的壓(ya)😄力和轉(zhuǎn)速都應(ying)降低,高(gao)溫條件(jiàn)下,則應(ying)增加泵(beng)的間隙(xi),并采用(yòng)耐熱材(cái)料 。
流動(dòng)穩定:流(liú)量與齒(chǐ)輪轉速(su)成正比(bǐ),與壓力(li)無關 流(liu)動平穩(wen):沒有脈(mò)動和壓(ya)力波峰(feng),不會産(chǎn)生管道(dao)顫🔴動。 多(duō)功能性(xìng):僅僅通(tong)過調整(zhěng)轉子軸(zhóu)的位置(zhì),同一台(tái)泵既可(kě)🤩以出來(lai)稀釋溶(rong)液又可(kě)以出來(lai)瀝青,糖(tang)漿,樹脂(zhī),聚合✍️物(wù)等高粘(zhan)度液體(ti)。 可逆性(xìng):可以通(tong)過改變(biàn)齒輪的(de)旋轉方(fang)向使液(ye)體反向(xiang)🍉流❌動,兩(liǎng)種方向(xiàng)都能充(chong)分發揮(huī)泵的性(xing)能 自吸(xī)性:由泵(beng)産生高(gāo)真空,允(yun)許在最(zui)大自吸(xī)高度實(shí)現快🏃🏻速(sù)自吸🌈,取(qǔ)決于泵(beng)送液體(ti)的物理(li)特性(溫(wen)度,蒸汽(qì)壓力,粘(zhan)度等👌)。 建(jiàn)議性:隻(zhi)有兩個(gè)活動部(bu)件:主動(dòng)輪和動(dòng)輪,隻有(you)一個軸(zhou)封。 堅固(gu)的重載(zai)結構:低(dī)轉速。特(tè)大球軸(zhóu)承的外(wai)部軸承(chéng)座可以(yǐ)❓承受⛷️軸(zhóu)向和徑(jing)向負載(zai)。 磨損率(lü)低:由于(yú)主動輪(lún)和從動(dong)齒輪不(bu)成倍數(shu)關系。這(zhe)就意味(wèi)着磨損(sun)可以被(bei)均勻的(de)分散在(zài)每個齒(chǐ)輪上。因(yīn)為一個(ge)齒輪上(shàng)的每一(yī)個齒輪(lún)接觸另(lìng)一個齒(chǐ)輪上的(de)每一個(gè)🙇♀️齒輪的(de)次數一(yī)樣。 磨損(sǔn)調節系(xì)統:轉子(zǐ)邊緣的(de)磨損可(ke)以通過(guò)調整轉(zhuan)子軸的(de)位置來(lái)補償。這(zhe)樣,即使(shi)在有相(xiang)當大的(de)磨損的(de)情況下(xia),也可以(yi)保證泵(bèng)的穩定(ding)性。 維護(hu)簡單,維(wei)護率低(di):不用移(yi)動泵,管(guan)道或泵(beng)驅動裝(zhuāng)置🐉就可(ke)以進行(háng)檢查和(hé)調節。 互(hu)動性:标(biāo)準組件(jian)的設計(jì)可實現(xian)不同材(cai)料和特(tè)性零部(bù)件之間(jiān)的替換(huan)。例如:有(you)多種軸(zhou)封系統(tong)可供選(xuan)擇,還可(ke)以安裝(zhuāng)帶夾套(tào)的㊙️外殼(ké)和軸蓋(gai)來代替(ti)标準部(bu)件。 端口(kou)位置可(ke)改變:泵(beng)殼可在(zài)軸承箱(xiang)上旋轉(zhuan)以從不(bu)同位置(zhì)💋處吸排(pai)液體。 預(yù)熱:加熱(rè)夾套或(huo)是與外(wai)殼鑄成(cheng)一體,或(huo)是安裝(zhuāng)在端蓋(gài)上,或是(shì)♈安裝在(zài)填料壓(ya)蓋上。 旁(páng)路安全(quán)閥:旁路(lù)安全閥(fa)安裝在(zai)泵上并(bìng)且容易(yì)調節,在(zài)🍉有些型(xing)号的泵(beng)上采取(qǔ)雙重安(an)全閥并(bìng)帶加熱(rè)夾套。 在開(kāi)始運轉(zhuan)前,往齒(chi)輪泵的(de)殼體内(nèi)灌滿待(dai)輸送的(de)液體,便(bian)于安全(quan)啟動。若(ruo)環境🚩溫(wēn)度低于(yú)冰點,應(yīng)預先向(xiàng)泵内通(tōng)入熱蒸(zhēng)汽,進行(háng)預熱處(chu)理,然後(hou)才可♍啟(qi)動齒輪(lún)泵。高粘(zhān)度泵的(de)旋轉方(fang)向要與(yǔ)進、出油(yóu)口相符(fú)。齒輪泵(beng)若是第(dì)一次運(yùn)行,或長(zhang)期閑置(zhì)後再使(shǐ)用,最好(hǎo)在空載(zai)或小負(fu)荷情況(kuang)下先跑(pǎo)合一小(xiǎo)時左右(you)。如果在(zai)跑㊙️合階(jie)👄段預先(xian)覺察出(chu)異常溫(wen)升、洩漏(lou)、振動和(hé)噪聲時(shí),應停機(jī)檢查。高(gāo)粘度齒(chǐ)輪泵的(de)支座或(huò)法蘭與(yǔ)其驅動(dong)電機應(yīng)采用共(gòng)同的安(ān)裝基礎(chu),基礎、法(fa)蘭或支(zhī)座均需(xu)具有足(zu)夠的剛(gang)度,以減(jiǎn)小齒輪(lun)泵運轉(zhuan)時産生(shēng)的振動(dong)和噪聲(sheng)。電動機(ji)與齒輪(lún)泵須用(yong)彈性聯(lián)軸器連(lián)接,同軸(zhou)度小于(yú)0.1毫米,傾(qīng)斜角不(bu)得大于(yú)1度。安裝(zhuang)聯軸器(qì)時不得(de)用錘敲(qiāo)打,以免(miǎn)傷害齒(chi)輪泵的(de)齒輪等(deng)零件。若(ruò)用帶輪(lun)、鍊輪等(deng)驅動時(shí)應設托(tuo)架🌈支承(chéng),以防主(zhǔ)動齒輪(lún)軸承受(shou)徑向力(lì)。緊固齒(chi)輪泵、電(diàn)動機的(de)地腳螺(luo)釘時,螺(luó)釘受力(li)應均勻(yún),連接可(ke)靠。用手(shǒu)✍️轉動聯(lian)軸器時(shí),應感覺(jiào)到齒輪(lun)泵能夠(gòu)輕松地(di)轉動,沒(mei)有卡緊(jin)等異常(cháng)現象出(chū)現,然後(hòu)才可以(yǐ)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(chǐ)輪泵的(de)吸油管(guǎn)道内徑(jing)應足夠(gou)大,并避(bi)免狹窄(zhai)通道或(huo)急♋劇拐(guai)彎、減少(shǎo)✨彎頭,去(qu)除不必(bì)要的閥(fá)門、附件(jian),盡可能(néng)🥰地降低(di)泵的安(ān)裝高度(du),縮短吸(xi)油管道(dao)的長度(dù),以減少(shao)壓力⁉️損(sǔn)失。管🛀接(jiē)頭等元(yuán)件的密(mi)封要🚶良(liáng)好,以防(fáng)止🐕空氣(qi)侵入✊,從(cóng)而控制(zhì)氣穴與(yǔ)氣蝕的(de)發生。止(zhǐ)回閥與(yu)安全閥(fá)在齒輪(lún)泵的輸(shu)出管路(lù)上最好(hao)安裝一(yī)個止回(hui)閥。這樣(yàng)在檢修(xiū)泵及輸(shu)💞出管道(dào)時,系統(tǒng)中的液(yè)體不會(huì)發生倒(dao)流。齒輪(lún)泵帶負(fù)荷停車(che)時,亦可(ke)防止泵(beng)倒轉而(ér)在其輸(shū)出管道(dào)内🏃🏻産生(sheng)局部真(zhen)空。應當(dang)注意,出(chu)口止回(hui)閥不能(néng)裝反🔞或(huo)出現卡(ka)死現象(xiang)。高粘度(du)泵的出(chū)口管路(lu)上還應(yīng)當設置(zhì)安全閥(fa)等保護(hu)裝置,這(zhè)樣一旦(dàn)泵的出(chū)口通道(dao)發生堵(du)塞🛀🏻,就可(ke)以打開(kai)安全閥(fa)📧卸壓。安(an)全閥可(kě)以與🔞泵(bèng)體或泵(bèng)蓋鑄成(cheng)一體,也(ye)可以單(dān)獨裝配(pei)。對于需(xū)要正反(fǎn)轉的高(gāo)粘度齒(chǐ)輪泵,其(qi)進出口(kou)管路上(shàng)均需設(she)置安全(quan)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.
