●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)内轉子泵。這種類型的泵自吸性能強,适用于輸送(sòng)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。具有體積小、重量輕、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. 該型泵可廣泛用于石油、化工、顔料、化工、顔(yá)料、食品、肥皂(zào)、洗滌劑及制藥等行業。This type of pump can be widely used in petroleum, chemical, pigment, chemical, pigment, food, soap, detergent and pharmaceutical industries. ●高粘(zhān)度泵使用時注意事項Matters needing attention when using high viscosity pump 進(jìn)、出口(kǒu)管路(lù)的管徑必須和泵保持一緻;The diameters of inlet and outlet piping must be consistent with pump; 設計管(guǎn)路時應盡量減(jiǎn)少彎頭,且彎頭角度不宜過小,進口管線不宜過長,以免(miǎn)影響自吸(xī)。 啟(qǐ)動前(qián)每個注油杯都應(yīng)家潤滑油,且保證(zhèng)每天加油一次。 泵在工作前應該點動啟動電機,觀察轉向是否和規定轉向一緻。 開機後(hòu)觀察運轉是否正常,如有不正(zhèng)常噪(zào)音、特殊振動或溫升過高等情況,應停機檢查。 注意皮帶松緊是否恰當,每半年調整一次(cì)。 ●高粘度泵工(gōng)作原理: 高粘度泵是容積式(shì)内(nèi)齧合齒輪泵,主(zhǔ)動齒輪(外轉子)帶動被動齒輪(lún)(内轉子)旋轉時,不斷産生封閉的空間,在吸油區齒輪(lún)逐漸脫(tuō)離齧合而液體不斷地充滿齒(chǐ)間并被帶到出油區(qū),齒輪在(zài)出油區進入齧合時液體被排出(chū)。兩個旋轉齒輪的共同作(zuò)用,形成一個穩(wěn)定的體積(jī)排(pái)量,沒有脈動。由于泵是完全(quán)對稱的,泵可以反轉,液流(liú)方向也随之改(gǎi)變。但應注意,泵的(de)轉向可能受到密封或(huò)泵内(nèi)其它結構的限(xiàn)制,用(yòng)戶有反轉要求時應在訂(dìng)貨時做出說明。 ●高粘度泵優點: 轉子泵的軸向位置可調,不需(xū)要拆泵。 泵采用(yòng)模(mó)塊化設計,可根據不同(tóng)的使用要求更換不同部件。可選夾層結構,以方便對泵加熱或冷卻,可以選擇是(shì)否帶安全閥,可以選擇不同的密封形式,詳見密封結構圖。泵的各個零(líng)件(jiàn)可以選用不同的(de)材質以适應具體使用要求。 不(bú)同的使用(yòng)條件(jiàn),泵的結構形式可能不同,具體應用請向廠家或本公司客戶代表咨詢。需要指出的是泵的轉速愈高,泵的(de)磨損愈嚴重,液體中如含有磨(mó)料物質,泵的材料應選用耐磨(mó)材質,在此種工況下,泵的壓力和轉速都應降低,高(gāo)溫條件下,則應增加(jiā)泵的間隙,并采用耐熱材料 。 流動穩定:流量與齒輪轉速成正比,與壓力無關 流動(dòng)平穩:沒(méi)有脈動和壓力波峰,不會産生管道顫動。 多功能性:僅僅通過調(diào)整轉子軸的位置,同(tóng)一台(tái)泵既可以出來稀釋溶(róng)液又可以出來瀝(lì)青,糖漿,樹脂,聚(jù)合物等高粘度(dù)液體。 可(kě)逆性:可以通過改變齒輪的旋轉方向(xiàng)使液體反(fǎn)向流(liú)動,兩種方向都(dōu)能充分發揮泵的性能 自吸性(xìng):由泵産生高真空,允許在最大自吸高度實現快速(sù)自吸,取決于泵送液體的(de)物理特性(溫度,蒸汽壓力,粘度等)。 建議性:隻有兩(liǎng)個活動部件:主動輪和動輪(lún),隻有一個軸封。 堅固的重載結(jié)構:低轉速。特(tè)大球軸承的外部(bù)軸承座可以承受軸向和徑向負載。 磨損(sǔn)率低:由于主動輪和(hé)從動齒輪不成倍數關系。這就(jiù)意味着磨損可(kě)以被均勻的(de)分散(sàn)在每個齒輪上。因(yīn)為一個齒(chǐ)輪上的每一個齒輪接(jiē)觸另一個齒輪(lún)上的每一個齒輪的次(cì)數一樣。 磨損調節系統:轉子邊緣的磨損可以通過調整轉子軸的位置(zhì)來補償。這樣,即使在(zài)有相當大的磨損的(de)情況下,也(yě)可以保證泵的穩定性。 維護簡單,維護率低:不用(yòng)移動泵(bèng),管道(dào)或泵驅(qū)動裝置就可以進行檢查和調節。 互動性(xìng):标準(zhǔn)組件的設計(jì)可實現不同材料和特性零部件之(zhī)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)可改變:泵殼可在軸承箱(xiāng)上(shàng)旋轉以(yǐ)從不同位置處吸排液體。 預熱:加熱夾套或是與外殼鑄成一體,或是安(ān)裝在端蓋上(shàng),或是安(ān)裝在填料壓蓋(gài)上。 旁(páng)路安全閥:旁路安全閥安(ān)裝在泵上并且容易調(diào)節,在有些型号的(de)泵上采取雙重安全閥并帶加熱夾套。 在開始運轉前,往齒輪泵的(de)殼體内灌滿待輸送的液(yè)體,便于安全啟(qǐ)動。若環境溫度低于冰點,應預先(xiān)向(xiàng)泵内通入熱蒸(zhēng)汽,進行預熱處理,然後才(cái)可啟動齒(chǐ)輪泵(bèng)。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(kōng)載或小負荷情況下先跑合一小時左右。如(rú)果在跑(pǎo)合階段預先覺察出(chū)異常溫升、洩漏(lòu)、振動和噪聲時,應停機檢(jiǎn)查。高粘度齒輪泵的支座(zuò)或法(fǎ)蘭與其驅動電機應采用共(gòng)同的安裝基礎,基礎、法蘭或(huò)支座(zuò)均需具有(yǒu)足夠的剛度,以減小齒輪泵運轉時(shí)産生的振動和(hé)噪聲。電動機與齒(chǐ)輪泵須用彈(dàn)性聯軸器連接,同軸度小(xiǎo)于0.1毫米,傾斜角不得大于(yú)1度。安裝聯軸器時不得用錘敲打,以免傷害齒(chǐ)輪泵的齒輪等零件。若用帶輪、鍊輪等驅動時應設托架支承,以防主動(dòng)齒輪軸承受徑(jìng)向力。緊固(gù)齒輪泵、電(diàn)動機的(de)地腳螺釘(dìng)時,螺釘受力應均勻,連(lián)接可靠。用手轉動聯軸器時,應感覺到齒輪泵能夠輕(qīng)松地轉動,沒有卡緊等異常現(xiàn)象出現,然後才可以配管。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. 高粘度齒輪(lún)泵的吸油管道内徑應足夠大,并避免狹窄通道或急劇拐彎(wān)、減少彎(wān)頭,去除不必要的閥門(mén)、附件,盡可能地降低泵的安裝高(gāo)度,縮短吸油(yóu)管道的長(zhǎng)度,以減少壓力損失。管接頭等元件的密封要良好,以防止空氣侵入,從而控(kòng)制氣穴與氣蝕的發生。止回閥與安全閥在齒(chǐ)輪泵的輸出管路上最好安裝一(yī)個止回閥。這樣在檢修泵及輸出(chū)管道時,系統中的液體不會發生倒流。齒輪泵帶負荷停車時,亦可防止泵倒轉而在其輸(shū)出管道(dào)内産(chǎn)生局部真空。應當注(zhù)意,出口止回閥不能(néng)裝(zhuāng)反或出(chū)現卡死現象。高粘度泵的(de)出口(kǒu)管路上還應當設置安全閥等保護(hù)裝置,這樣一旦泵的出口通道(dào)發生堵塞,就可(kě)以打開安(ān)全閥卸壓(yā)。安全閥可以與泵體或泵蓋鑄成一(yī)體,也(yě)可以單獨裝配。對于需要正反轉的高粘度齒輪泵,其進出口管路(lù)上均需設置安全閥。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.
