●高粘度泵概述High viscosity pump overview NYP型内(nèi)環(huán)式高粘度泵是(shì)一種容積式内轉子(zǐ)泵。這種類(lèi)型的泵自吸性能強,适用于輸送不含固體顆粒和纖維的粘(zhān)稠液體,甚至是半固體狀态的液體,最高輸送粘度達到3*105厘泊。具有體積小、重(zhòng)量輕、脈動小(xiǎo)、噪(zào)音低、運(yùn)轉平穩、壽命長等優點(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. 該型泵可廣泛用于石油、化工、顔料、化(huà)工、顔料、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. ●高粘度泵使用時(shí)注意事項(xiàng)Matters needing attention when using high viscosity pump 進、出口管路的管徑(jìng)必須(xū)和泵保持一緻;The diameters of inlet and outlet piping must be consistent with pump; 設計(jì)管路時應盡量減少(shǎo)彎頭,且彎頭角度不(bú)宜過小,進口管線不宜過長,以免影(yǐng)響自吸。 啟動前每個注油杯都應家潤滑油,且保證每天加油一次。 泵在工作前應該點動啟(qǐ)動電機,觀察轉(zhuǎn)向是否和規(guī)定轉向一緻。 開(kāi)機後觀察運(yùn)轉是否正常,如有(yǒu)不正常噪音、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。 ●高(gāo)粘度泵工作原理: 高粘度泵是容(róng)積式内齧合齒輪泵(bèng),主動齒輪(外轉子)帶動被動齒輪(内轉子)旋轉時,不斷産生封(fēng)閉的空間,在吸油區齒輪逐漸(jiàn)脫離齧合而液體不(bú)斷地充滿齒間并被帶到出油區,齒輪在出油區進入齧合時液體(tǐ)被排(pái)出。兩個旋轉齒輪的共同作用,形成(chéng)一個穩定的體積排量,沒有脈動。由于泵是完全對稱(chēng)的(de),泵(bèng)可以反轉,液流方向也随(suí)之改變。但應注意(yì),泵的轉向可能(néng)受到密(mì)封或泵内其它結構的(de)限制,用戶有反轉要求時應在(zài)訂貨時做出說明。 泵在(zài)起動過程中應特别注意以下(xià)幾(jǐ)個問題: 起動前要檢查下列(liè)内容: 檢查泵、齒輪箱和電機的對中程度(dù); 檢查過濾器中(zhōng)有沒有焊皮和金屬渣; 檢查各連接部位連接(jiē)是否緊固; 檢查管(guǎn)路壓在泵上的力和力(lì)矩是否超過給定的(de)數值,如果溫度較高,還應檢查管路是否有膨脹節; 檢查(chá)電氣連接的正确性及電機的額(é)定(dìng)值,并檢查電機轉動(dòng)方向(xiàng)是否正确(què); 檢查泵的轉動方(fāng)向是否正确; 如有安全閥,安全閥安裝必須正确(què), 檢查泵軸是否轉動靈活; 泵的内部不能是幹的,特别是需要自吸的時候,應(yīng)向泵内灌注一(yī)些油或輸送的液體(tǐ); 泵組(zǔ)裝時在零件(jiàn)的表面有防護液(yè),如果這種液體不(bú)能和泵送液體相容,則必須清洗; 最好在管路上安裝壓力表和真(zhēn)空表,方便觀察泵的工作狀(zhuàng)态; 檢查機械密(mì)封箱是否注滿(mǎn)液體; 檢查管路的閥門是否打開; 如(rú)果用(yòng)内燃機驅動,請在起動發動機前保持離合器脫開; 泵起動後,檢查(chá)液體是否進入到泵中,泵是否(fǒu)工作正常,如果長時間(jiān)無液體進入泵中,應停機檢查泵(bèng)及管路。 ●高粘度齒輪泵并不能産生壓力,它隻是輸出流量(liàng)。壓力低或無壓力(lì),說明(míng)高(gāo)粘度齒 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(pái)量選(xuǎn)得過大或壓力(lì)調得過高(gāo)時,也會造成壓力不足 當然,壓力表損壞或壓(yā)力表節流孔堵塞(sāi)時也顯(xiǎn)示不出壓力,此時可換裝一個新的壓力表檢查。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. 如果确認泵無流量輸出,可能是(shì)由于泵安裝有誤、泵(bèng)的轉向不(bú)對,或吸人側(進液口及吸液管道)堵塞、出(chū)口止回閥裝反(fǎn)或卡(kǎ)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,這種現象往往是由于泵的驅動裝置打滑或功率不(bú)足所緻。此時應檢查(chá)齒 輪(lún)泵的實際轉速、泵與電動(dòng)機的聯接(jiē)及功(gōng)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.
