80CYZ32自吸油泵配Y7.5KW-52電機流量13.5m3/h,揚程(chéng)32米,汽蝕餘量4米(mǐ),進(jìn)出口徑80,軸(zhóu)功率6.8KW,轉速(sù)2900r/min. 柴油是輕質石(shí)油産品,複雜烴類(碳原子數約10~22)混合物。為柴油機燃料(liào)。主要由原油蒸餾、催化裂化、熱裂化、加氫裂化(huà)、石油焦化等過(guò)程生産的(de)柴油餾分調配而成;也可由頁岩油加工和煤液化(huà)制取。分為輕柴油(yóu)(沸(fèi)點範圍約180~370℃)和重柴油(沸點範圍約350~410℃)兩大類。廣泛用于大(dà)型車輛、鐵路機車(chē)、船艦。 柴油最重(zhòng)要用途是用于車輛、船(chuán)舶的柴油發動機。與汽油相比,柴油能量密度高,燃油消耗率低,但廢(fèi)氣中含有害成分(fèn)(NO,顆粒物等)較多。 由于柴油機(jī)較汽(qì)油(yóu)機熱效率高,功率大,燃料單耗低,比較經濟,故應用日(rì)趨廣泛(fàn)。它主要作(zuò)為拖拉機、大型汽車、内燃機車及土建、挖掘機、裝載機(jī)、漁船(chuán)、柴油發電機組和農用(yòng)機械的動力。柴油是複雜(zá)的烴類混合物,碳原子數約(yuē)為10-22。 0号柴油: 主要由原油蒸餾,催(cuī)化裂化,加氫(qīng)裂化,減粘裂化,焦化等過程生産的柴油餾分調配而成(還需經精制和加入添(tiān)加(jiā)劑)。柴油(yóu)分為輕柴油(沸點範(fàn)圍(wéi)約180℃ ~370℃)和重柴油(沸點範(fàn)圍約350℃ ~410℃)兩大類。柴油使用性能中最重要(yào)的是着(zhe)火性和流動性,其(qí)技術指标(biāo)分别為十六烷值和凝點(diǎn),我國柴油現(xiàn)行規格中要求含硫量(liàng)控制在0.5%-1.5%。 柴油按(àn)凝點分級(jí),輕柴油有10、5、0、-10、-20、-35、-50六個牌(pái)号,重柴油有10、20、30三個牌号(hào)。 一般來講(jiǎng),5#柴油适合于氣溫在8℃以上時使(shǐ)用;0# 柴油适用于氣溫在8℃至4℃時使用;-10#柴油适(shì)用于氣溫在4℃至-5℃時使用;-20#柴油适(shì)用于氣溫在-5℃至(zhì)-14℃時使用;-35#柴油适(shì)用于(yú)氣溫在-14℃至-29℃時使用;-50#柴油适用于氣溫在-29℃至-44℃或者低(dī)于該溫度時使用。 物理特性(xìng): 熱值(zhí)為3.3*10^7J/L; 沸(fèi)點範圍(wéi)和黏度介于煤油與潤滑油之間(jiān)的液态石油餾(liú)分。易燃易揮發,不(bú)溶于水,易溶于醇(chún)和其(qí)他有(yǒu)機溶劑。是組分複雜的混合物,沸點範圍:十六烷值;有 180℃ ~370℃ 和 350℃ ~410℃ 兩類。 自吸泵的(de)自吸高度,與葉輪前密封間隙、泵的轉數、分離室液面高度等因素有關。葉輪前密封間隙越小,自吸高度越大,一般取為0.3~0.5毫米;在間隙增大時,除自吸高度下降外,泵的揚(yáng)程、效率均降低(dī)。泵的自吸高度随葉(yè)輪的圓周速度u2的增大而增大,但到(dào)最大自吸高度(dù)時,轉數增(zēng)加而自吸(xī)高度就不(bú)再增加了,此時隻是縮短自吸時間;當轉(zhuǎn)數(shù)下降時,自吸高度則随着下降。在其它條件不變的情況下,自吸高度還随着儲(chǔ)水高度的增加(jiā)而增加(但也不(bú)能超過分離室(shì)的最佳儲水高(gāo)度(dù))。為了在自吸泵中更好地使氣水混(hùn)合,葉輪的葉片須(xū)少些,使葉栅的節距增大;并宜采用半開式葉輪(或葉輪槽道較寬(kuān)的葉(yè)輪),這樣更方便于回水深入地射(shè)進葉輪葉栅中。 自吸泵大部分與内燃(rán)機配套,裝在可移動(dòng)的小車上,宜于野外作業(yè)。Self-priming pump self-priming height, and before the impeller seal clearance, the revolutions of the pump, separation chamber level and other factors.Before the impeller seal gap is smaller, the greater the self-priming height, general take 0.3 ~ 0.5 mm;Increase in clearance, in addition to the self-priming height decreased, pump lift and efficiency are reduced.The self-priming pump 自吸油泵的使用及維護The use and maintenance of self-priming pump 1 啟動前的準備及(jí)檢查事項(xiàng)1 to start preparing and check the item before 1.1 檢查軸承體油腔中潤(rùn)滑油(yóu)是否已達到規定(dìng)要求,潤滑油的油位應(yīng)保持在機油尺的兩刻線(xiàn)之間或油标中線位(wèi)置,不得過多或不足.1.1 check whether oil bearing body cavity, the lubricating oil has reached the specified requirements, the lubricating oil in the oil level should be kept in the oil foot or oil standard midline position between two scribed line, not too much or not. 1.2 檢查泵體内的(de)儲液是否高于葉輪邊緣.如若不足,可以(yǐ)從泵體上的加液口直接向泵(bèng)體内注入儲液,不應在儲液不足的情(qíng)況下啟動運轉,否(fǒu)則泵體不能正(zhèng)常工作,且易損壞機(jī)械密封.1.2 check reservoir is higher than that of the impeller in the pump body. If not, can add liquid mouth from the pump body directly to the pump body into the reservoir, the defects in the reservoir should not start operation, under the condition of pump body can not work normally, and easy to damage the mechanical seal. 1.3 檢查泵轉動部件是否(fǒu)有卡住磕碰現象.1.3 check the pump rotating components for stuck knock against. 1.4 檢查泵體底腳及各(gè)連接處(chù)有(yǒu)無松動現象.1.4 check the pump body foot and joint have loose phenomenon. 1.5 檢查泵軸與原動機主軸的同軸度與平衡度.1.5 check the pump shaft and prime mover of main shaft alignment and balance. 1.6 檢查進(jìn)口管路是否漏氣1.6 check whether import pipeline leak 1.7 打開吸入管道的閥門(注意不(bú)要全開)1.7 open the suction piping valves (be careful not to open) 2 啟動及操作(zuò)2 start-up and operation 2.1 啟動(dòng)油泵,注意泵軸的轉向是(shì)否正确2.1 start the oil pump, pay attention to the steering pump shaft is correct 2.2 注意轉動時(shí)有無(wú)異常噪(zào)音和(hé)振動2.2 notice there is no abnormal noise and vibration 2.3 注意真空表(biǎo)讀數(shù),啟動後當壓力表及真空表的(de)讀數經過(guò)一段時間的波動而時針(zhēn)穩定後,說明泵内已經上液,油泵竟如正常工作狀體.2.3 pay attention to the vacuum meter reading, starts when the pressure gauge and vacuum gauge readings over a period of time after hour due to the variation of stable, explain within the pump has been on fluid, oil pump body become like a normal job. 2.4 在泵進入正常輸油作(zuò)業前,應特(tè)别注意泵内油(yóu)溫升(shēng)高情況,如(rú)果這個過程長,泵内油溫過高,則應停泵檢查原因.2.4 before the pump into the normal oil operation, should pay special attention to pump the high oil temperature rise, if the process is long, inside the pump oil temperature is too high, you should stop the pump to check. 2.5 如果泵内(nèi)溫度過(guò)高而引起自吸困難.可暫時(shí)停機,利用出口(kǒu)管路中的液體倒流或直接向泵内補充(chōng)液體,使泵内液體降溫,即可啟動.2.5 if the high temperature caused by self-priming pump difficult. Can temporarily stop, using the export pipeline fluid replacement in the liquid backflow or directly to the pump, cooling the liquid in the pump, can be started. 2.6 泵在工作過程中因故停泵,需在啟動時,把出口控制(zhì)閥稍開.這樣既有利于自吸過程中(zhōng)其他從吐出口排出,又能保證泵在(zài)較輕(qīng)的負荷下啟(qǐ)動.2.6 pump in the process of work for pump stopped, at startup, the export control valve slightly open. This is beneficial to both other exported from spitting out during the process of imbibition, and can guarantee the pump starts under a lighter load. 2.7 泵每工作15-20小時(shí)或每次使用前應(yīng)檢查并及時(shí)補充(chōng)一次(cì)10号(hào)機械油.2.7 pump every 15 to 20 hours or every time before the use should check and added a number 10 machine oil in time. 3 停車 3.1 關閉吐出管路(lù)上的閘閥(fá) 3.2 使泵停止轉動 4 易損件的維護(hù) 4.1 滾動軸承:當油泵長期(qī)運動後(hòu),油泵磨損到一定程度必須更換 4.2 前(qián)後(hòu)密封環:當密封(fēng)環磨損到一定程度時,須進行更換 4.3 機械密封:在不漏(lòu)油的情況下,一(yī)般不應拆開檢查,若軸承體下端洩漏口處産生嚴重洩(xiè)露時,則應對機械密封進行拆檢.裝拆機械密(mì)封時,必須輕取輕放,注意配合面的清潔,不好好動、靜環表面(miàn)的光(guāng)潔度,嚴禁敲擊碰撞。
