●高粘度泵概述(shù)High viscosity pump overview NYP型内環式高粘(zhan)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(han)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(dá)到3*105厘泊。具有體(tǐ)積小、重量輕、脈(mò)動小、噪音低、運(yun)轉平穩、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. 該型泵(bèng)可廣泛用于石(shí)油、化工、顔料、化(huà)工、顔料、食品、肥(féi)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(zhan)度泵使用時注(zhu)意事項Matters needing attention when using high viscosity pump 進、出口(kǒu)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(du)不宜過小,進口(kou)管線不宜過長(zhang),以免影響自吸(xi)。 啟動前每個注(zhù)油杯都應家潤(rùn)滑油,且保證每(mei)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(fou)和規🧑🏽🤝🧑🏻定轉向一(yi)緻。 開機後觀察(chá)運轉是否正常(chang),如有不正常噪(zào)音、特殊🌍振動或(huò)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(ban)年調整一次。 ●高(gao)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(chǐ)輪(外轉子)帶動(dòng)被動齒輪(内轉(zhuǎn)子)旋轉時,不斷(duàn)産🧡生封閉的空(kong)間,在吸油區齒(chi)輪逐漸脫離齧(nie)合🌈而液體不斷(duan)地充滿齒間并(bing)被帶到出油區(qū),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(jī)排量,沒有脈動(dong)。由于泵是完全(quan)對稱的,泵可以(yǐ)反轉,液流方向(xiang)也随之改變。但(dàn)應注意,泵的轉(zhuǎn)向可能受到密(mi)封或泵内其它(tā)結構的限制,用(yòng)戶有反轉要求(qiu)時應在訂貨時(shí)做出說明。 ●高粘(zhan)度泵優點: 轉子(zi)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(ju)不同的使用要(yao)求更換不同⁉️部(bu)件。可選夾層結(jie)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(fēng)結構圖。泵的各(ge)個零件可以選(xuan)用不同的材質(zhì)以适應具體使(shǐ)用要求。
流動穩定:流(liu)量與齒輪轉速(su)成正比,與壓力(lì)無關 流動平穩(wěn):沒有脈動和壓(yā)力波峰,不會産(chan)生管道顫📱動。 多(duō)功能性:僅僅通(tong)過調整轉子軸(zhou)的位置,同一台(tái)泵既可🐪以🐆出來(lai)稀釋溶液又可(ke)以出來瀝青,糖(táng)漿,樹脂,聚合物(wù)等高粘度液體(ti)。 自吸性:由泵(bèng)産生高真空,允(yun)許在最大自吸(xi)高度實現快速(su)自吸,取決于泵(bèng)送液體的物理(lǐ)特性(溫度,蒸汽(qì)壓📐力,粘度等🈲)。 建(jiàn)議性:隻有兩個(gè)活動部件:主動(dong)輪和動輪,隻有(you)一❓個軸🏒封。 磨損調節系(xi)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(zhe)樣,即使在有相(xiàng)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(wéi)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(biao)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(zhuāng)帶夾⛹🏻♀️套的📧外殼(ke)和軸蓋來代替(tì)标準🤟部件。 端口(kǒu)位置可改變:泵(beng)殼可在軸承箱(xiang)上旋轉以從不(bu)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(huò)是安裝在端蓋(gai)上,或⁉️是安裝在(zài)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(yi)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(zhuan)前,往齒輪泵的(de)殼體内灌滿待(dai)輸送的液體,便(biàn)于安全啟動。若(ruò)環💯境溫度低于(yu)冰點,應預先向(xiàng)泵内通入熱蒸(zhēng)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(fāng)向要與進、出油(yóu)口相符。齒輪泵(beng)若是第一次運(yun)行,或長期閑置(zhì)後再使用,最好(hǎo)在空載或小負(fu)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(lòu)、振動和噪聲時(shí)💯,應停機🏃檢查。高(gāo)粘度齒輪泵的(de)支座或法蘭與(yu)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(xu)具有足夠的剛(gang)度,以減小齒輪(lun)泵運轉時産生(sheng)的振動和噪聲(shēng)。電動機與齒輪(lun)泵須用彈性聯(lián)軸器連接,同軸(zhou)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(chǐ)輪泵的齒輪等(deng)零件。若用帶輪(lún)、鍊輪等驅動時(shi)應設托架支承(cheng),以防🐉主動齒輪(lun)軸承受徑向力(lì)。緊固齒輪泵、電(dian)動機的地腳螺(luo)釘時,螺釘受力(li)應均勻,連接可(kě)靠。用手🔴轉動聯(lian)軸器時,應感覺(jiao)到齒輪泵能夠(gou)輕松地轉動,沒(méi)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(jìng)應足夠大,并避(bi)免狹窄通道或(huo)急劇拐彎、減少(shao)🚶♀️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(dào)的長度,以減少(shao)壓力損失。管接(jiē)頭等元件的密(mì)封要良好,以防(fang)止空氣侵入,從(cóng)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(shū)出管路上最好(hǎo)安裝一個止回(hui)閥。這樣在檢修(xiū)泵及輸出管🥵道(dao)時,系統中的液(yè)體不會發生倒(dao)流。齒輪泵帶負(fù)荷停車時,亦可(ke)防止泵倒轉而(ér)在其輸出管道(dào)内産🈚生局部真(zhēn)空。應當注意,出(chū)口止回閥不能(neng)裝反或出現卡(ka)💁死現🌈象。高粘度(dù)泵的出口管路(lù)上還應當設置(zhì)安全閥等保護(hu)裝置,這樣一旦(dàn)泵的出口通道(dao)發生堵塞,就可(kě)以打開安全閥(fá)卸壓。安全閥可(ke)以與泵體或泵(beng)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(chǐ)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.
