80cyz32自吸油泵配(pèi)y7.5kw-52電機流量(liàng)13.5m3/h,揚程(chéng)32米,汽蝕(shí)餘量4米(mǐ),進出口(kǒu)徑80,軸功(gōng)率6.8kw,轉速2900r/min.    柴油是(shì)輕質石油産品(pǐn)，複雜(zá)烴類(碳原(yuán)子數(shù)約10～22)混(hùn)合物(wù)。為柴油機(jī)燃料(liào)。主要(yào)由原(yuán)油蒸餾、催化裂化、熱(rè)裂化(huà)、加氫裂化、石油焦(jiāo)化等過(guò)程生産(chǎn)的(de)柴油(yóu)餾(liú)分調配而成(chéng)；也可由(yóu)頁(yè)岩(yán)油加工和煤液化(huà)制取(qǔ)。分為輕柴油（沸(fèi)點範(fàn)圍約(yuē)180～370℃）和重柴油（沸點(diǎn)範圍約(yuē)350～410℃）兩大類(lèi)。廣泛用于(yú)大型車輛、鐵(tiě)路機車、船艦(jiàn)。

     柴(chái)油(yóu)最重(zhòng)要用(yòng)途(tú)是用于(yú)車輛(liàng)、船舶的(de)柴(chái)油發(fā)動機(jī)。與汽(qì)油相比(bǐ)，柴(chái)油能(néng)量密(mì)度(dù)高，燃油(yóu)消耗率低(dī)，但廢(fèi)氣中含有害成分（no，顆(kē)粒物(wù)等）較(jiào)多。

    由于柴油機(jī)較汽(qì)油機熱效(xiào)率(lǜ)高(gāo)，功率大，燃(rán)料單耗低，比(bǐ)較經濟，故應用日趨廣泛。它(tā)主要(yào)作為(wéi)拖拉機、大型汽車(chē)、内燃機車及(jí)土建、挖(wā)掘(jué)機、裝(zhuāng)載(zǎi)機(jī)、漁船、柴油發(fā)電機組和農(nóng)用(yòng)機(jī)械的(de)動力。柴油是複(fú)雜的烴類混(hùn)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(jiā)氫裂化，減(jiǎn)粘裂化，焦(jiāo)化等(děng)過(guò)程(chéng)生産的柴(chái)油餾(liú)分調(diào)配而成(chéng)（還需經(jīng)精(jīng)制和(hé)加入添(tiān)加劑）。柴油分為輕柴油（沸點範圍約(yuē)180℃ ～370℃）和(hé)重(zhòng)柴油（沸點(diǎn)範圍約350℃ ～410℃）兩(liǎng)大類。柴油使用性能中最重要(yào)的是着火性和流動性，其技術指标分别為十六(liù)烷(wán)值和凝點(diǎn)，我國柴油現行(háng)規格(gé)中要求含(hán)硫量控(kòng)制在0.5%-1.5%。      柴(chái)油按(àn)凝點分級，輕(qīng)柴油有10、5、0、-10、-20、-35、-50六個(gè)牌号(hào)，重柴油有(yǒu)10、20、30三個牌号。    一般(bān)來講(jiǎng)，5#柴(chái)油适合(hé)于氣(qì)溫(wēn)在(zài)8℃以上時使用(yòng)；0# 柴油适(shì)用于(yú)氣溫(wēn)在8℃至(zhì)4℃時使(shǐ)用(yòng)；－10#柴油适(shì)用于(yú)氣溫在4℃至(zhì)－5℃時使用；－20#柴(chái)油适用于氣溫在－5℃至(zhì)－14℃時使(shǐ)用；－35#柴油(yóu)适(shì)用于氣溫在－14℃至(zhì)－29℃時使用(yòng)；－50#柴油适(shì)用于氣(qì)溫在－29℃至(zhì)－44℃或者低于該溫(wēn)度時使(shǐ)用。

    物(wù)理(lǐ)特性:    熱值(zhí)為3.3*10^7j/l;    沸(fèi)點範圍(wéi)和黏度(dù)介于煤油與潤滑油之間的液(yè)态石(shí)油餾分。易(yì)燃易揮發，不溶(róng)于水，易(yì)溶于醇和其(qí)他有機溶(róng)劑。是(shì)組分(fèn)複雜(zá)的混合(hé)物，沸點範圍(wéi):十(shí)六烷值(zhí);有 180℃ ～370℃ 和 350℃ ～410℃ 兩類。    自吸泵的(de)自吸高度，與(yǔ)葉輪前(qián)密封間隙(xì)、泵(bèng)的轉數(shù)、分離室液(yè)面高度等(děng)因(yīn)素有關(guān)。葉輪前(qián)密封間(jiān)隙越小(xiǎo)，自吸高(gāo)度越(yuè)大(dà)，一般(bān)取(qǔ)為0.3~0.5毫米；在間隙(xì)增大時，除自吸(xī)高度(dù)下降外，泵(bèng)的揚程、效率均(jun1)降低(dī)。泵的自吸(xī)高度(dù)随葉輪的圓周(zhōu)速度u2的增(zēng)大而(ér)增大，但到(dào)最大(dà)自吸高度(dù)時，轉數增加而(ér)自吸高度就不(bú)再增加(jiā)了(le)，此時(shí)隻是(shì)縮短自吸(xī)時間；當轉數下(xià)降時(shí)，自吸高度(dù)則随(suí)着(zhe)下(xià)降。在(zài)其它(tā)條件不變(biàn)的情況下，自吸(xī)高度(dù)還随着儲(chǔ)水高(gāo)度(dù)的增加而增加（但(dàn)也不(bú)能超(chāo)過分離室(shì)的最(zuì)佳儲水高(gāo)度）。為(wéi)了在(zài)自吸泵中更好(hǎo)地使(shǐ)氣水混合(hé)，葉輪的葉片須少些(xiē)，使葉栅的節距增大(dà)；并宜采用(yòng)半開式葉輪（或(huò)葉輪槽道較寬(kuān)的葉輪(lún)），這樣更方便(biàn)于回(huí)水深(shēn)入地射進葉輪(lún)葉栅中。

自吸泵(bèng)大部分與(yǔ)内燃(rán)機配(pèi)套(tào)，裝(zhuāng)在可移動(dòng)的(de)小車上(shàng)，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(de)使用及(jí)維護(hù)the use and maintenance of self-priming pump

    1 啟動(dòng)前的準(zhǔn)備及檢(jiǎn)查事(shì)項1 to start preparing and check the item before

    1.1 檢查軸(zhóu)承(chéng)體油(yóu)腔中潤(rùn)滑油(yóu)是否已(yǐ)達(dá)到規定要(yào)求，潤(rùn)滑油的油位應(yīng)保持(chí)在機油尺的兩(liǎng)刻線之間(jiān)或油标中(zhōng)線位(wèi)置,不(bú)得過多或(huò)不足(zú).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(jiǎn)查(chá)泵體(tǐ)内的(de)儲(chǔ)液是否(fǒu)高于葉輪(lún)邊緣(yuán).如若不足,可以(yǐ)從泵(bèng)體上的加(jiā)液口直接向泵(bèng)體内注入儲液,不應在(zài)儲液不(bú)足的(de)情況下啟(qǐ)動運轉,否則泵(bèng)體不能正常工(gōng)作,且(qiě)易(yì)損(sǔn)壞機(jī)械(xiè)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(jiǎn)查泵(bèng)轉動(dòng)部件是否(fǒu)有卡住磕碰現(xiàn)象.1.3 check the pump rotating components for stuck knock against.

    1.4 檢(jiǎn)查(chá)泵體底腳及(jí)各連接處(chù)有無(wú)松動現象(xiàng).1.4 check the pump body foot and joint have loose phenomenon.

    1.5 檢查泵軸與(yǔ)原動機主軸的同(tóng)軸度與(yǔ)平衡度(dù).1.5 check the pump shaft and prime mover of main shaft alignment and balance.

    1.6 檢查(chá)進口管路(lù)是否漏氣(qì)1.6 check whether import pipeline leak

    1.7 打開吸入(rù)管道的閥(fá)門(注意(yì)不(bú)要全(quán)開)1.7 open the suction piping valves (be careful not to open)

    2 啟動(dòng)及操作(zuò)2 start-up and operation

    2.1 啟動油泵,注意(yì)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(zhù)意轉(zhuǎn)動時(shí)有無(wú)異常噪音和振動2.2 notice there is no abnormal noise and vibration

    2.3 注意真(zhēn)空表讀數,啟動後當(dāng)壓力表及真空(kōng)表的讀數經過(guò)一段(duàn)時間的波動而(ér)時針穩定後,說(shuō)明(míng)泵内已經上(shàng)液,油泵竟如正常工作(zuò)狀(zhuàng)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(zài)泵進入正常輸(shū)油作業(yè)前,應特(tè)别注意泵(bèng)内油(yóu)溫升高情況,如果這個過程長(zhǎng),泵内油溫過高(gāo),則應(yīng)停(tíng)泵(bèng)檢查(chá)原因(yīn).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(gāo)而引(yǐn)起自吸(xī)困(kùn)難.可(kě)暫時停(tíng)機(jī),利用(yòng)出口管(guǎn)路中的(de)液體倒(dǎo)流或直接向(xiàng)泵内(nèi)補(bǔ)充(chōng)液體,使(shǐ)泵内液(yè)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(gōng)作過(guò)程(chéng)中因故(gù)停泵(bèng),需在啟(qǐ)動(dòng)時,把(bǎ)出口控制閥稍(shāo)開.這樣既(jì)有利(lì)于自(zì)吸過程中(zhōng)其他從吐出口(kǒu)排出(chū),又能保(bǎo)證(zhèng)泵在較(jiào)輕的負荷下啟(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(xiǎo)時或每(měi)次使(shǐ)用前(qián)應檢(jiǎn)查并(bìng)及(jí)時補充(chōng)一次(cì)10号(hào)機械油(yóu).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(bì)吐出(chū)管路(lù)上的閘閥(fá)

    3.2 使泵停(tíng)止(zhǐ)轉動(dòng)
