我公司生産(chan)的NYP高粘度泵用作(zuò)高粘度打膠泵是(shì)非常合适的泵從(cong)結構上看:自吸性(xing)能強，适用于輸送(sòng)不含固體☂️顆粒和(hé)纖維的粘稠液體(tǐ)，甚至是半固體狀(zhuang)态的液體，最高輸(shu)送粘度達到3*105厘泊(bo)。具有體積小、重量(liang)輕、脈動小、噪音低(dī)、運轉平穩、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.●高粘度泵(beng)工作原理：

　　高粘度(du)泵是容積式内齧(niè)合齒輪泵，主動齒(chi)輪（外轉子）帶動被(bei)動齒輪（内轉子）旋(xuan)轉時，不斷産生封(feng)閉的空間，在吸油(yóu)區齒輪逐漸脫離(lí)齧合而液體不🌏斷(duàn)地充滿齒間并被(bèi)帶到出油區，齒輪(lún)在出油區進入齧(nie)合時液☔體被排出(chū)。兩個旋轉齒輪的(de)共同作用，形成一(yī)個穩定的體積排(pai)量，沒有脈動。由🌍于(yu)泵是完全對稱的(de)，泵可以反轉，液流(liú)方向也随之改變(bian)。但應注意，泵的轉(zhuǎn)向可能受到密封(feng)或泵内其它結構(gòu)的✉️限制，用⛹🏻‍♀️戶有反(fan)轉要求時應在訂(dìng)貨時做出說明。　　

●高(gāo)粘度泵優點：

　　轉子(zi)泵的軸向位置可(ke)調，不需要拆泵。

　　泵(bèng)采用模塊化設計(jì)，可根據不同的使(shǐ)用要求更換不同(tóng)部件☔。可選夾層結(jie)構，以方便對泵加(jia)熱或冷卻，可以選(xuǎn)擇是否帶安全閥(fa)🧑🏽‍🤝‍🧑🏻，可以選擇不同的(de)密封形式，詳見密(mi)封結構圖。泵的各(ge)個零件可以選用(yong)不同的材質以适(shì)應具體📞使用要求(qiú)。

　　不同的使用條件(jian)，泵的結構形式可(ke)能不同，具體應用(yòng)請向廠家或本公(gōng)司客戶代表咨詢(xún)。需要指出的是泵(beng)的轉速愈高，泵的(de)磨損愈嚴重，液體(tǐ)中如含有磨料物(wù)質，泵的✊材料應選(xuan)用耐磨材質，在此(ci)種工況下，泵的壓(yā)力和轉速都應降(jiang)低，高溫條件下，則(ze)應增加泵的間隙(xi)，并采用耐熱✨材料(liao) 。

　　流動穩定：流量與(yu)齒輪轉速成正比(bi)，與壓力無關

　　流動(dòng)平穩：沒有脈動和(he)壓力波峰，不會産(chǎn)生管道顫動。

　　多功(gōng)能性：僅僅通過調(diao)整轉子軸的位置(zhi)，同一台泵既可以(yǐ)出來稀釋溶液又(yòu)可以出來瀝青，糖(tang)漿，樹脂，聚合物等(deng)高粘度液🌈體。

　　可逆(ni)性：可以通過改變(bian)齒輪的旋轉方向(xiang)使液體反向流✊動(dong)，兩種方向都能充(chōng)分發揮泵的性能(néng)

　　自吸性：由泵産生(shēng)高真空，允許在最(zuì)大自吸高度實現(xiàn)快速自吸，取決于(yú)泵送液體的物理(lǐ)特性（溫度，蒸⚽汽壓(yā)力，粘度等）。

　　建議性(xìng)：隻有兩個活動部(bu)件：主動輪和動輪(lun)，隻有一個軸封。

　　堅(jiān)固的重載結構：低(dī)轉速。特大球軸承(chéng)的外部軸承座可(kě)以承受軸向和徑(jing)向負載。

　　磨損率低(dī)：由于主動輪和從(cóng)動齒輪不成倍數(shù)關系。這就意味着(zhe)磨損可以被均勻(yun)的分散在每個齒(chǐ)輪💯上。因🔴為一個齒(chi)輪上的每㊙️一個齒(chǐ)輪接觸另一個齒(chi)📐輪上的每一個齒(chǐ)輪的次數一樣。

磨(mo)損調節系統：轉子(zi)邊緣的磨損可以(yǐ)通過調整轉子軸(zhóu)📞的位置來補償。這(zhe)樣，即使在有相當(dang)大的磨損⚽的情況(kuàng)下📐，也可以保證泵(bèng)的穩定性。

　　維護簡(jiǎn)單，維護率低：不用(yong)移動泵，管道或泵(beng)驅動裝置就🛀可以(yǐ)進行檢查和調節(jie)。

　　互動性：标準組件(jiàn)的設計可實現不(bú)同材料和特性🌈零(líng)部件之間的替換(huan)。例如：有多種軸封(fēng)系統可供選擇，還(hai)可以安裝帶夾套(tao)的外殼和軸蓋來(lái)代替标準部件。

　　端(duān)口位置可改變：泵(bèng)殼可在軸承箱上(shàng)旋轉以從不☀️同位(wèi)置處吸排液體。

　　預(yù)熱：加熱夾套或是(shì)與外殼鑄成一體(tǐ)，或是安裝在端蓋(gài)上，或是💁安裝在填(tián)料壓蓋上。

　　旁路安(ān)全閥：旁路安全閥(fa)安裝在泵上并且(qiě)容易調節，在有些(xiē)型号的泵上采取(qu)雙重安全閥并帶(dai)加熱夾套。●高粘度(du)泵的工作壓力的(de)選定

　　1, select the work pressure

　　高粘度泵額(e)定的壓力是指泵(beng)連續工作時的最(zui)高♈許用壓力，而其(qí)工作壓力則決定(ding)于外部負載，安裝(zhuāng)和調📧試的壽命與(yu)其🐕工作壓力直接(jie)相關。對于不頻繁(fan)工作的齒輪泵，其(qí)工作壓力可取為(wéi)泵的額定壓力，考(kao)慮到産品質量🍉不(bú)同，最好将額定壓(yā)力降低20%～30%使用。對于(yu)經常工作于較高(gao)壓力下的齒輪泵(bèng)，其工作壓力應比(bi)泵的額定壓力低(dī)1～2個壓力級。石油化(hua)工設備常常是24小(xiao)時連續運轉，這時(shi)泵的工作壓力應(ying)該取得比額定壓(yā)力低👣得多，且工作(zuo)轉速也應該低于(yu)額定轉速。如果高(gao)粘度齒輪泵的工(gong)作壓力調整過高(gāo)，則會使齒輪泵在(zài)超負荷下運行。High viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.For not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.For often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.Petrochemical equipment are often 24 hours of continuous operation, and at this time of the pump working pressure should be obtained was much lower than the rated pressure, and the work speed should be lower than the rated speed.If the high viscosity gear pump high pressure adjustment, will make the pump running under overload.

●NYP高(gāo)粘度泵的安裝與(yǔ)試運轉

　　Installation and commissioning

　　高粘度泵(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(zhī)座均需具有足夠(gou)的🥰剛度，以減小齒(chi)輪泵運轉時産生(sheng)的振動和噪聲。電(dian)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(dà)于1度。安裝聯軸器(qì)時不得用錘敲打(dǎ)，以免傷害齒輪泵(beng)的齒輪等零件。若(ruo)用帶輪、鍊輪等驅(qū)動時應設托架💋支(zhī)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(luo)釘受力應均勻，連(lián)接可靠。用⛷️手轉動(dong)♋聯軸器時，應感覺(jiao)到齒輪泵能夠輕(qīng)松地轉動，沒有卡(ka)緊等異常現象出(chu)現，然後才可🙇‍♀️以配(pei)管。高粘度齒輪泵(beng)的吸油管道内徑(jìng)應足夠大，并避免(miǎn)狹窄通道或急劇(jù)拐彎、彎頭，去除不(bu)必要的閥門、附件(jian)，盡可能地降低泵(bèng)的安裝高✨度，縮✨短(duan)吸油管道的長度(dù)，以減少壓力損失(shī)。管接頭等元件的(de)密封要良好，以防(fáng)止空氣侵入，從而(er)👈控制氣穴與氣蝕(shí)的發生。在開始運(yùn)轉前，往齒輪泵的(de)殼體内灌滿待輸(shū)送的液體，便于安(an)全動。若環境😘溫度(dù)💃低于冰點，應預先(xian)向泵内通入熱蒸(zhēng)汽，進行預熱處理(li)，然後才可啟動齒(chǐ)輪泵。齒輪泵的旋(xuan)轉方向要與進、出(chū)油口相符。齒輪泵(bèng)若是第一次運行(hang)，或長期閑置後再(zài)使用，最好在空載(zǎi)或小負荷情況下(xia)先跑合一小時左(zuǒ)右。如果在跑合階(jiē)段預先覺出異常(chang)溫升、洩漏、振動和(hé)噪聲時，應機檢查(chá)。高粘度泵的出口(kǒu)管路☔上還應當設(shè)置安全閥等保護(hù)裝置，這樣一旦泵(beng)的出口通道發生(shēng)堵塞，就可以打開(kai)🌈安全閥卸壓。對于(yu)需要正反轉的高(gao)粘度齒輪泵，其進(jin)出口管路上均需(xu)設置安全閥。High viscosity pump bearing or flange and its drive motor should use common installation basis, 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 gear and other parts of the gear pump.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.High viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp bend, bend, 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.Before starting operation, to gear pump casing filled with liquid, easy to safety.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.Direction of rotation of the gear pump, 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 the abnormal temperature rise, leakage, vibration and noise, should machine inspection.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.For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
