80CYZ32自吸(xi)油泵配(pei)Y7.5KW-52電機流(liú)量13.5m3/h,揚程(chéng)32米,汽蝕(shí)餘量4米(mi),進出口(kou)徑80,軸功(gōng)率6.8KW,轉速(sù)2900r/min.    柴油是(shì)輕質石(shi)油産品(pin)，複雜烴(ting)類(碳原(yuan)子數約(yuē)10～22)混合物(wu)。為柴油(yóu)機燃料(liao)。主要由(you)原油蒸(zhēng)餾、催化(hua)裂化、熱(re)裂化、加(jia)氫裂化(hua)、石油焦(jiāo)化等過(guò)程生産(chan)的柴油(you)餾分調(diao)配而成(chéng)；也可由(you)頁岩油(yóu)加工和(he)煤液化(hua)制取。分(fèn)為輕柴(chái)油（沸點(dian)範圍約(yuē)180～370℃）和重柴(chái)油（沸點(diǎn)範圍約(yuē)350～410℃）兩大類(lèi)。廣泛用(yong)于大型(xíng)車輛、鐵(tiě)路機車(chē)、船艦。

     柴(chai)油最重(zhong)要用途(tú)是用于(yú)車輛、船(chuán)舶的柴(chái)油發動(dòng)機。與汽(qì)油相比(bǐ)，柴油能(neng)量密度(dù)高，燃油(yóu)消耗率(lǜ)低，但廢(fèi)氣中含(hán)有害成(chéng)分（NO，顆粒(li)物等）較(jiao)多。

    由于(yú)柴油機(ji)較汽油(you)機熱效(xiao)率高，功(gōng)率大，燃(ran)料單耗(hào)低，比較(jiào)經濟，故(gu)應用日(ri)趨廣泛(fan)。它主要(yao)作為拖(tuō)拉機、大(dà)型汽車(che)、内燃機(jī)車及土(tu)建、挖掘(jue)機、裝載(zai)機、漁船(chuán)、柴油發(fa)電機組(zu)和農用(yòng)機械的(de)動力。柴(chai)油是複(fú)雜的烴(ting)類混合(he)物，碳原(yuan)子數約(yue)為12-13。

    0号柴(chái)油:    主要(yao)由原油(you)蒸餾，催(cuī)化裂化(huà)，加氫裂(liè)化，減粘(zhān)裂化，焦(jiāo)化等過(guò)程生産(chan)的柴油(you)餾分調(diao)配而成(cheng)（還需經(jing)精制和(he)加入添(tiān)加劑）。柴(chai)油分為(wei)輕柴油(you)（沸點範(fàn)圍約180℃ ～370℃）和(hé)重柴油(you)（沸點範(fan)圍約350℃ ～410℃）兩(liang)大類。柴(chai)油使用(yong)性能中(zhōng)最重要(yào)的是着(zhe)火性和(he)流動性(xing)，其技術(shu)指标分(fen)别為十(shí)六烷值(zhí)和凝點(diǎn)，我國柴(chai)油現行(háng)規格中(zhong)要求含(han)硫量控(kòng)制在0.5%-1.5%。      柴(chái)油按凝(níng)點分級(ji)，輕柴油(you)有10、5、0、-10、-20、-35、-50六個(ge)牌号，重(zhòng)柴油有(you)10、20、30三個牌(pái)号。    一般(bān)來講，5#柴(chai)油适合(hé)于氣溫(wen)在8℃以上(shàng)時使用(yong)；0# 柴油适(shi)用于氣(qì)溫在8℃至(zhi)4℃時使用(yòng)；－10#柴油适(shi)用于氣(qi)溫在4℃至(zhi)－5℃時使用(yong)；－20#柴油适(shì)用于氣(qì)溫在－5℃至(zhi)－14℃時使用(yong)；－35#柴油适(shì)用于氣(qì)溫在－14℃至(zhì)－29℃時使用(yong)；－50#柴油适(shì)用于氣(qi)溫在－29℃至(zhì)－44℃或者低(di)于該溫(wēn)度時使(shǐ)用。

    物理(lǐ)特性:    熱(rè)值為3.3*10^7J/L;    沸(fei)點範圍(wei)和黏度(du)介于煤(mei)油與潤(run)滑油之(zhī)間的液(ye)态石油(you)餾分。易(yì)燃易揮(hui)發，不溶(róng)于水，易(yi)溶于醇(chun)和其他(ta)有機溶(rong)劑。是組(zǔ)分複雜(za)的混合(hé)物，沸點(diǎn)範圍:十(shí)六烷值(zhí);有 180℃ ～370℃ 和 350℃ ～410℃ 兩(liang)類。    自吸(xī)泵的自(zi)吸高度(du)，與葉輪(lun)前密封(fēng)間隙、泵(beng)的轉數(shù)、分離室(shi)液面高(gao)度等因(yin)素有關(guān)。葉輪前(qián)密封間(jiān)隙越小(xiǎo)，自吸高(gao)度越大(da)，一般取(qu)為0.3~0.5毫米(mi)；在間隙(xi)增大時(shí)，除自吸(xī)高度下(xia)降外，泵(beng)的揚程(cheng)、效率均(jun)降低。泵(bèng)的自吸(xi)高度随(sui)葉輪的(de)圓周速(sù)度u2的增(zēng)大而增(zeng)大，但到(dào)最大自(zi)吸高度(dù)時，轉數(shù)增加而(er)自吸高(gao)度就不(bu)再增加(jiā)了，此時(shí)隻是縮(suo)短自吸(xi)時間；當(dāng)轉數下(xià)降時，自(zì)吸高度(du)則随着(zhe)下降。在(zài)其它條(tiao)件不變(biàn)的情況(kuàng)下，自吸(xī)高度還(hái)随着儲(chu)水高度(dù)的增加(jiā)而增加(jia)（但也不(bu)能超過(guò)分離室(shì)的最佳(jiā)儲水高(gao)度）。為了(le)在自吸(xī)泵中更(geng)好地使(shǐ)氣水混(hun)合，葉輪(lun)的葉片(piàn)須少些(xiē)，使葉栅(shan)的節距(ju)增大；并(bìng)宜采用(yòng)半開式(shì)葉輪（或(huo)葉輪槽(cao)道較寬(kuan)的葉輪(lun)），這樣更(geng)方便于(yú)回水深(shēn)入地射(she)進葉輪(lún)葉栅中(zhōng)。

自吸泵(bèng)大部分(fèn)與内燃(ran)機配套(tao)，裝在可(ke)移動的(de)小車上(shang)，宜于野(ye)外作業(ye)。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(yóu)泵的使(shi)用及維(wei)護The use and maintenance of self-priming pump

    1 啟動(dòng)前的準(zhǔn)備及檢(jian)查事項(xiàng)1 to start preparing and check the item before

    1.1 檢查軸(zhóu)承體油(you)腔中潤(rùn)滑油是(shi)否已達(da)到規定(ding)要求，潤(run)滑油的(de)油位應(yīng)保持在(zài)機油尺(chi)的兩刻(kè)線之間(jian)或油标(biao)中線位(wèi)置,不得(de)過多或(huo)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(jiǎn)查泵體(tǐ)内的儲(chǔ)液是否(fǒu)高于葉(yè)輪邊緣(yuan).如若不(bú)足,可以(yi)從泵體(ti)上的加(jiā)液口直(zhi)接向泵(bèng)體内注(zhù)入儲液(ye),不應在(zai)儲液不(bú)足的情(qíng)況下啟(qǐ)動運轉(zhuan),否則泵(beng)體不能(neng)正常工(gōng)作,且易(yi)損壞機(jī)械密封(feng).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(bèng)轉動部(bu)件是否(fǒu)有卡住(zhu)磕碰現(xian)象.1.3 check the pump rotating components for stuck knock against.

    1.4 檢查(chá)泵體底(di)腳及各(gè)連接處(chu)有無松(song)動現象(xiàng).1.4 check the pump body foot and joint have loose phenomenon.

    1.5 檢查泵(bèng)軸與原(yuan)動機主(zhǔ)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 檢查進(jìn)口管路(lu)是否漏(lòu)氣1.6 check whether import pipeline leak

    1.7 打開(kai)吸入管(guan)道的閥(fa)門(注意(yì)不要全(quan)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(you)泵,注意(yì)泵軸的(de)轉向是(shi)否正确(que)2.1 start the oil pump, pay attention to the steering pump shaft is correct

    2.2 注意轉(zhuǎn)動時有(yǒu)無異常(chang)噪音和(hé)振動2.2 notice there is no abnormal noise and vibration

    2.3 注(zhù)意真空(kong)表讀數(shù),啟動後(hou)當壓力(lì)表及真(zhen)空表的(de)讀數經(jing)過一段(duàn)時間的(de)波動而(er)時針穩(wěn)定後,說(shuo)明泵内(nèi)已經上(shang)液,油泵(beng)竟如正(zheng)常工作(zuò)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(zài)泵進入(ru)正常輸(shu)油作業(ye)前,應特(te)别注意(yi)泵内油(you)溫升高(gāo)情況,如(rú)果這個(gè)過程長(zhǎng),泵内油(you)溫過高(gao),則應停(ting)泵檢查(cha)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(rú)果泵内(nèi)溫度過(guò)高而引(yin)起自吸(xi)困難.可(ke)暫時停(tíng)機,利用(yong)出口管(guǎn)路中的(de)液體倒(dǎo)流或直(zhí)接向泵(bèng)内補充(chong)液體,使(shǐ)泵内液(yè)體降溫(wen),即可啟(qi)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(zai)工作過(guo)程中因(yin)故停泵(beng),需在啟(qǐ)動時,把(ba)出口控(kong)制閥稍(shāo)開.這樣(yàng)既有利(lì)于自吸(xi)過程中(zhōng)其他從(cóng)吐出口(kǒu)排出,又(you)能保證(zhèng)泵在較(jiào)輕的負(fù)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(měi)工作15-20小(xiao)時或每(mei)次使用(yong)前應檢(jian)查并及(ji)時補充(chōng)一次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(guan)閉吐出(chu)管路上(shàng)的閘閥(fa)

    3.2 使泵停(ting)止轉動(dong)

    4 易損件(jiàn)的維護(hù)
