●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内轉子泵。這種類型的泵自吸性能強,适用于輸送不含固體顆粒和纖維的粘稠液體,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,且彎頭角度不宜過小,進口管線不宜過長,以免影響自吸。 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動電機,觀察轉向是否和規定轉向一緻。 開機後觀察運轉是否正常,如有不正常噪音、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。 ●高粘度泵工作原理: 高粘度泵是容積式内齧合齒輪泵,主動齒輪(外轉子)帶動被動齒輪(内轉子)旋轉時,不斷産生封閉的空間,在吸油區齒輪逐漸脫離齧合而液體不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被排出。兩個旋轉齒輪的共同作用,形成一個穩定的體積排量,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或泵内其它結構的限制,用戶有反轉要求時應在訂貨時做出說明。 泵在起動過程中應特别注意以下幾個問題: 起動前要檢查下列内容: 檢查泵、齒輪箱和電機的對中程度; 檢查過濾器中有沒有焊皮和金屬渣; 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矩是否超過給定的數值,如果溫度較高,還應檢查管路是否有膨脹節; 檢查電氣連接的正确性及電機的額定值,并檢查電機轉動方向是否正确; 檢查泵的轉動方向是否正确; 如有安全閥,安全閥安裝必須正确, 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,應向泵内灌注一些油或輸送的液體; 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容,則必須清洗; 最好在管路上安裝壓力表和真空表,方便觀察泵的工作狀态; 檢查機械密封箱是否注滿液體; 檢查管路的閥門是否打開; 如果用内燃機驅動,請在起動發動機前保持離合器脫開; 泵起動後,檢查液體是否進入到泵中,泵是否工作正常,如果長時間無液體進入泵中,應停機檢查泵及管路。 ●高粘度齒輪泵并不能産生壓力,它隻是輸出流量。壓力低或無壓力,說明高粘度齒 輪泵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,壓力表損壞或壓力表節流孔堵塞時也顯示不出壓力,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,可能是由于泵安裝有誤、泵的轉向不對,或吸人側(進液口及吸液管道)堵塞、出口止回閥裝反或卡死了,也有可能是驅動軸斷裂了。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足所緻。此時應檢查齒 輪泵的實際轉速、泵與電動機的聯接及功率匹配情況等。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.
