80CYZ32自吸(xi)油泵配Y7.5KW-52電機(ji)流量13.5m3/h,揚程32米(mǐ),汽蝕餘量4米(mi),進出口徑80,軸(zhóu)功率6.8KW,轉速2900r/min. 柴(chai)油是輕質石(shí)油産品,複雜(za)烴類(碳原子(zi)數約10~22)混合物(wu)。為柴油機燃(ran)料。主要由原(yuán)油蒸餾、催化(huà)裂化、熱裂化(hua)、加氫裂化、石(shi)油焦化等過(guo)程生産的柴(chai)油餾分調配(pèi)而成;也可由(you)頁岩油加工(gong)和煤液化制(zhi)取。分為輕柴(chai)油(沸點範圍(wéi)約180~370℃)和重柴油(you)(沸點範圍約(yuē)350~410℃)兩大類。廣泛(fàn)用于大型車(chē)輛、鐵路機車(chē)、船艦。 柴油最(zuì)重要用途是(shi)用于車輛、船(chuan)舶的柴油發(fā)動機。與汽油(yóu)相比,柴油能(neng)量密度高,燃(ran)油消耗率低(di),但廢氣中含(han)有害成分(NO,顆(ke)粒物等)較多(duo)。 由于柴油機(ji)較汽油機熱(rè)效率高,功率(lü)大,燃料單耗(hào)低,比較經濟(jì),故應用日趨(qū)廣泛。它主要(yao)作為拖拉機(ji)、大型汽車、内(nei)燃機車及土(tǔ)建、挖掘機、裝(zhuāng)載機、漁船、柴(chai)油發電機組(zǔ)和農用機械(xie)的動力。柴油(you)是複雜的烴(tīng)類混合物,碳(tan)原子數約為(wei)12-07。 0号柴油: 主要(yao)由原油蒸餾(liú),催化裂化,加(jiā)氫裂化,減粘(zhān)裂化,焦化等(deng)過程生産的(de)柴油餾分調(diào)配而成(還需(xū)經精制和加(jia)入添加劑)。柴(chai)油分為輕柴(chai)油(沸點範圍(wéi)約180℃ ~370℃)和重柴油(yóu)(沸點範圍約(yuē)350℃ ~410℃)兩大類。柴油(yóu)使用性能中(zhōng)最重要的是(shi)着火性和流(liu)動性,其技術(shu)指标分别為(wéi)十六烷值和(he)凝點,我國柴(chái)油現行規格(gé)中要求含硫(liú)量控制在0.5%-1.5%。 柴(chai)油按凝點分(fen)級,輕柴油有(yǒu)10、5、0、-10、-20、-35、-50六個牌号,重(zhong)柴油有10、20、30三個(ge)牌号。 一般來(lái)講,5#柴油适合(he)于氣溫在8℃以(yǐ)上時使用;0# 柴(chái)油适用于氣(qi)溫在8℃至4℃時使(shǐ)用;-10#柴油适用(yong)于氣溫在4℃至(zhi)-5℃時使用;-20#柴油(yóu)适用于氣溫(wēn)在-5℃至-14℃時使用(yòng);-35#柴油适用于(yú)氣溫在-14℃至-29℃時(shi)使用;-50#柴油适(shi)用于氣溫在(zai)-29℃至-44℃或者低于(yu)該溫度時使(shi)用。 物理特性(xing): 熱值為3.3*10^7J/L; 沸點(dian)範圍和黏度(du)介于煤油與(yu)潤滑油之間(jian)的液态石油(you)餾分。易燃易(yì)揮發,不溶于(yú)水,易溶于醇(chún)和其他有機(jī)溶劑。是組分(fèn)複雜的混合(hé)物,沸點範圍(wéi):十六烷值;有(yǒu) 180℃ ~370℃ 和 350℃ ~410℃ 兩類。 自吸(xī)泵的自吸高(gao)度,與葉輪前(qian)密封間隙、泵(beng)的轉數、分離(lí)室液面高度(dù)等因素有關(guan)。葉輪前密封(fēng)間隙越小,自(zi)吸高度越大(da),一般取為0.3~0.5毫(háo)米;在間隙增(zeng)大時,除自吸(xi)高度下降外(wai),泵的揚程、效(xiào)率均降低。泵(bèng)的自吸高度(du)随葉輪的圓(yuan)周速度u2的增(zeng)大而增大,但(dan)到最大自吸(xi)高度時,轉數(shu)增加而自吸(xi)高度就不再(zai)增加了,此時(shi)隻是縮短自(zi)吸時間;當轉(zhuan)數下降時,自(zì)吸高度則随(suí)着下降。在其(qí)它條件不變(biàn)的情況下,自(zì)吸高度還随(suí)着儲水高度(dù)的增加而增(zeng)加(但也不能(neng)超過分離室(shì)的最佳儲水(shui)高度)。為了在(zài)自吸泵中更(geng)好地使氣水(shui)混合,葉輪的(de)葉片須少些(xiē),使葉栅的節(jiē)距增大;并宜(yi)采用半開式(shi)葉輪(或葉輪(lun)槽道較寬的(de)葉輪),這樣更(geng)方便于回水(shuǐ)深入地射進(jìn)葉輪葉栅中(zhong)。 自吸泵大部(bù)分與内燃機(jī)配套,裝在可(kě)移動的小車(che)上,宜于野外(wai)作業。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(you)泵的使用及(jí)維護The use and maintenance of self-priming pump 1 啟動前(qian)的準備及檢(jian)查事項1 to start preparing and check the item before 1.1 檢查(cha)軸承體油腔(qiang)中潤滑油是(shi)否已達到規(guī)定要求,潤滑(hua)油的油位應(yīng)保持在機油(you)尺的兩刻線(xian)之間或油标(biāo)中線位置,不(bu)得過多或不(bú)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(ti)内的儲液是(shì)否高于葉輪(lún)邊緣.如若不(bú)足,可以從泵(bèng)體上的加液(yè)口直接向泵(beng)體内注入儲(chu)液,不應在儲(chu)液不足的情(qíng)況下啟動運(yun)轉,否則泵體(tǐ)不能正常工(gong)作,且易損壞(huai)機械密封.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(jian)查泵轉動部(bù)件是否有卡(ka)住磕碰現象(xiàng).1.3 check the pump rotating components for stuck knock against. 1.4 檢查泵體底(dǐ)腳及各連接(jie)處有無松動(dong)現象.1.4 check the pump body foot and joint have loose phenomenon. 1.5 檢查泵(beng)軸與原動機(ji)主軸的同軸(zhou)度與平衡度(du).1.5 check the pump shaft and prime mover of main shaft alignment and balance. 1.6 檢查進口管(guan)路是否漏氣(qi)1.6 check whether import pipeline leak 1.7 打開吸入管(guan)道的閥門(注(zhu)意不要全開(kai))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 啟動油泵,注(zhù)意泵軸的轉(zhuǎn)向是否正确(que)2.1 start the oil pump, pay attention to the steering pump shaft is correct 2.2 注意轉動時(shí)有無異常噪(zao)音和振動2.2 notice there is no abnormal noise and vibration 2.3 注(zhu)意真空表讀(dú)數,啟動後當(dāng)壓力表及真(zhēn)空表的讀數(shu)經過一段時(shi)間的波動而(ér)時針穩定後(hòu),說明泵内已(yǐ)經上液,油泵(beng)竟如正常工(gōng)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(bèng)進入正常輸(shū)油作業前,應(yīng)特别注意泵(beng)内油溫升高(gāo)情況,如果這(zhe)個過程長,泵(beng)内油溫過高(gao),則應停泵檢(jiǎn)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(guǒ)泵内溫度過(guo)高而引起自(zi)吸困難.可暫(zàn)時停機,利用(yong)出口管路中(zhong)的液體倒流(liú)或直接向泵(bèng)内補充液體(ti),使泵内液體(ti)降溫,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 泵在工作(zuò)過程中因故(gu)停泵,需在啟(qi)動時,把出口(kǒu)控制閥稍開(kai).這樣既有利(lì)于自吸過程(chéng)中其他從吐(tu)出口排出,又(yòu)能保證泵在(zai)較輕的負荷(he)下啟動.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(mei)工作15-20小時或(huo)每次使用前(qián)應檢查并及(ji)時補充一次(cì)10号機械油.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(ting)車 3.1 關閉吐出(chu)管路上的閘(zhá)閥 3.2 使泵停止(zhi)轉動 4 易損件(jian)的維護 4.1 滾動(dong)軸承:當油泵(beng)長期運動後(hòu),油泵磨損到(dào)一定程度必(bì)須更換 4.2 前後(hou)密封環:當密(mì)封環磨損到(dao)一定程度時(shi),須進行更換(huàn) 4.3 機械密封:在(zài)不漏油的情(qíng)況下,一般不(bú)應拆開檢查(chá),若軸承體下(xia)端洩漏口處(chu)産生嚴重洩(xiè)露時,則應對(duì)機械密封進(jìn)行拆檢.裝拆(chai)機械密封時(shí),必須輕取輕(qing)放,注意配合(hé)面的清潔,不(bu)好好動、靜環(huán)表面的光潔(jie)度,嚴禁敲擊(jī)碰撞。
