●高粘度泵概(gài)述High viscosity pump overview NYP型内環式高粘度泵是一(yī)種容積式内轉子(zǐ)泵。這種類型的泵自(zì)吸性能(néng)強,适用(yòng)于輸送不(bú)含固體顆粒和纖維的粘(zhān)稠液體,甚(shèn)至是半固體狀态的液體(tǐ),最高輸送粘度達(dá)到3*105厘泊。具有體積(jī)小、重(zhòng)量輕、脈動小、噪音低、運轉平穩(wěn)、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(xíng)泵可廣泛用于石油、化工、顔料、化工、顔料、食品、肥皂、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. ●高粘度泵使用時注意事項Matters needing attention when using high viscosity pump 進、出口管路的管徑必須和泵(bèng)保持一緻;The diameters of inlet and outlet piping must be consistent with pump; 設計管路時應盡量減少彎頭,且彎(wān)頭角度不宜過(guò)小,進口管(guǎn)線不(bú)宜過長,以免影響(xiǎng)自吸。 啟動前每個注油杯都應家潤滑油,且(qiě)保證每天加油一次。 泵在工作前應該點動啟動電機,觀察轉向是否和規(guī)定轉向一緻。 開機後觀察運(yùn)轉是否正常,如有(yǒu)不(bú)正常噪音、特殊(shū)振動或溫升過高等情況,應停機檢查。 注意皮帶松(sōng)緊是否恰當,每半年(nián)調整一次。 ●高粘度泵工作原理(lǐ): 高粘(zhān)度泵是容積式内齧合齒(chǐ)輪泵,主動(dòng)齒輪(外轉子)帶動被動齒輪(内轉子)旋轉時,不斷産生封閉的空間,在吸油區齒輪逐漸(jiàn)脫離齧合而液體不(bú)斷地充滿齒間并(bìng)被帶(dài)到出油區,齒輪在出油區進入(rù)齧合時液體(tǐ)被排(pái)出。兩個旋轉齒輪的共同作用(yòng),形成(chéng)一個穩定的體積(jī)排量,沒有脈動。由于泵是完全對稱的,泵可以反轉,液流方向也随之改變。但應注意,泵的轉向可能受到密封(fēng)或泵内其它結構的限制,用戶有反轉要求時應在(zài)訂貨時做出說明。 泵在起動過程中(zhōng)應特别(bié)注意以下幾個問題: 起(qǐ)動前要檢查下列(liè)内容: 檢查泵、齒輪箱和(hé)電(diàn)機的對中程度; 檢查過濾器中有沒有焊皮和金(jīn)屬(shǔ)渣; 檢查各連接部位連接是否緊固; 檢查管路壓在泵上的力和力(lì)矩是否超過給定的數值(zhí),如果溫度較高,還應檢查管路是否(fǒu)有膨脹節; 檢查電氣(qì)連接(jiē)的正确性及電機的額定值,并檢查電機轉(zhuǎn)動方向(xiàng)是否正确; 檢查泵的轉動方向是否正确; 如有安全閥,安全閥安裝(zhuāng)必須正确, 檢查泵軸是否轉動靈(líng)活; 泵的内部不能(néng)是幹的,特(tè)别是需要自吸的時候,應向泵内灌注一些油或輸送的液體(tǐ); 泵組裝時在零件的表面有防護液,如果這種液體不能和泵送液體相(xiàng)容,則必須清洗; 最好在管路上(shàng)安裝(zhuāng)壓力表和真空表,方便觀(guān)察泵的工作狀态; 檢查機械(xiè)密封箱是否注滿液體; 檢查管路(lù)的閥門(mén)是否打開; 如果用内燃機驅動(dòng),請在起動發動機前保持離合器脫開(kāi); 泵起動後,檢查液體是否進入到泵中,泵是否工作(zuò)正常,如果長時間無液體進入泵中,應停(tíng)機檢(jiǎn)查泵及管路。 ●高粘度齒輪泵并不(bú)能産生(shēng)壓力,它隻是輸出流量。壓力低或無壓力,說明高粘度齒(chǐ) 輪泵(bèng)沒有吸入液體或洩漏嚴重。High viscosity gear pump does not generate pressure, it is only the output flow.Pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious. 電(diàn)動機輸出功率偏小、齒 輪泵排量選得過大或壓力調得過高時,也會造成壓力不足 當然,壓(yā)力表損壞(huài)或壓力表節流孔堵塞時(shí)也顯示不出壓力,此時可(kě)換裝一個新的壓力表檢(jiǎn)查(chá)。Small motor output power, gear wheel pump capacity to choose too large or pressure too high, can cause stress Pressure gauge damage or pressure gauge orifice jams, of course, also could not show pressure, can change a new pressure gauge to check at this time. 如果确認泵(bèng)無流量輸出,可能是(shì)由于泵安裝有誤、泵的轉向不對,或吸人側(進液口及(jí)吸液管道)堵塞、出口止回閥裝(zhuāng)反或卡死了,也有可能是驅動軸斷裂了(le)。If confirmed that no flow pump output, could be turned to the pumps due to pump installation is wrong, wrong, or suction side (liquid into the mouth and suck liquid pipeline jam, export check valve installed backwards, or card is dead, it is possible that the drive shaft fracture. 高粘度泵在轉速過低時會引起出液量不足,這種(zhǒng)現象往(wǎng)往是由于泵的驅動裝置打滑(huá)或功率不足所緻(zhì)。此時應檢查齒 輪(lún)泵的實際轉速、泵與電動機的聯接(jiē)及功率匹配情況等。High viscosity pump in low speed can cause insufficient quantity of produced liquid, this phenomenon is often due to the slippage of the pump drive or insufficient power.Check the gear wheel pump at this time of the actual speed, pump and motor connection and power matching, etc.
