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),進出口徑80,軸(zhóu)功率6.8KW,轉(zhuǎn)速2900r/min. 柴油是輕質石(shí)油産品,複雜烴類(lèi)(碳原子數約10~22)混合物。為柴油機燃料(liào)。主要由原油蒸(zhēng)餾、催化裂化、熱裂化(huà)、加氫裂化、石油焦化等過(guò)程生産的柴油餾分調配而成;也可由頁岩油加工和煤液化制取。分為輕柴油(沸(fèi)點(diǎn)範圍約180~370℃)和重柴油(yóu)(沸點範圍約350~410℃)兩大類。廣泛用于大型車(chē)輛、鐵(tiě)路機車、船艦。 柴油最重(zhòng)要(yào)用途是用于車輛、船舶的柴油發動(dòng)機。與汽(qì)油相比,柴油能量密度高,燃(rán)油消耗率低,但廢(fèi)氣中含有害成分(NO,顆粒物等)較多。 由(yóu)于柴油機(jī)較汽油機熱效率高,功率大,燃料單耗低(dī),比較經濟,故應用(yòng)日(rì)趨廣泛。它主要作為拖拉機、大型汽(qì)車、内燃機車及土(tǔ)建、挖掘機、裝載機、漁船、柴油發電機組和農用機械的動(dòng)力。柴油是複雜(zá)的烴類混合物,碳(tàn)原子數約為10-22。 0号柴油: 主要由原油蒸餾,催化裂化,加(jiā)氫裂化,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)加劑)。柴油分為輕柴油(沸點範圍約180℃ ~370℃)和重柴油(沸點範圍約350℃ ~410℃)兩大類。柴油使用性能中最重要的是着火性和流動(dòng)性(xìng),其技術(shù)指标分别(bié)為十六烷值和凝點(diǎn),我國柴油現行規格中要求含硫量控制(zhì)在0.5%-1.5%。 柴(chái)油按(àn)凝點分級(jí),輕柴油有10、5、0、-10、-20、-35、-50六個牌(pái)号(hào),重柴油有10、20、30三個牌号(hào)。 一般(bān)來講,5#柴油适合于氣溫在8℃以上時使用;0# 柴油适用于氣(qì)溫在8℃至4℃時使用;-10#柴油适(shì)用于氣溫在4℃至-5℃時使(shǐ)用;-20#柴油适用于氣溫在-5℃至-14℃時(shí)使用;-35#柴油适用于氣溫在-14℃至-29℃時使用;-50#柴油适用于氣溫在-29℃至-44℃或者低于該溫(wēn)度時使用。 物理特性: 熱值為3.3*10^7J/L; 沸點範圍和(hé)黏度介于煤(méi)油與潤(rùn)滑油之間的液(yè)态石油餾分。易燃易揮發(fā),不溶于水,易溶于醇(chún)和其他有機溶(róng)劑(jì)。是(shì)組分複雜的混(hùn)合物,沸點(diǎn)範圍:十六(liù)烷值;有 180℃ ~370℃ 和 350℃ ~410℃ 兩類。 自吸泵的自吸高度(dù),與葉輪前密封間隙、泵的轉數(shù)、分離室液面高度等(děng)因素有關。葉輪前(qián)密封間隙越小,自吸高(gāo)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。泵(bèng)的自吸高度随葉輪的(de)圓周速度u2的增大而增大,但到最大自吸高度時,轉數增加而自吸高度就不再增加了,此時隻是縮短自吸時間;當轉數下降時,自吸高度則(zé)随着下降。在其(qí)它條件不變(biàn)的情況下(xià),自吸高度還(hái)随着(zhe)儲(chǔ)水高度的增加而增加(但(dàn)也不能超過分離室的最佳儲水高(gāo)度)。為了在自吸泵中更好地使氣水混合,葉輪的葉片須(xū)少些(xiē),使葉栅的節(jiē)距增大;并宜采用(yòng)半開式葉輪(lún)(或葉輪槽道(dào)較寬的葉輪),這樣更方便于(yú)回水深入地射(shè)進葉輪葉栅中。 自吸(xī)泵大部分與(yǔ)内燃機配套,裝在可移動的小車上,宜于野外作業。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 自吸油泵的使用及維護The use and maintenance of self-priming pump 1 啟動前的準備及檢查事項1 to start preparing and check the item before 1.1 檢查軸(zhóu)承體油腔中潤滑油是否已達到規定要求,潤滑油的油位應保持在機(jī)油尺的兩刻線之間或油标中線位置,不得過(guò)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(jiǎn)查泵體内的(de)儲液是否高于葉輪(lún)邊緣(yuán).如若不足,可以從泵體上的(de)加液口直接向泵體内注(zhù)入儲液,不應在儲液不(bú)足的(de)情況下啟動運轉,否則泵體不能正(zhèng)常工(gōng)作,且易損壞機械密封.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 檢查泵轉動部件是否有卡住磕碰現象.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(zhóu)的同(tóng)軸度與平衡度(dù).1.5 check the pump shaft and prime mover of main shaft alignment and balance. 1.6 檢(jiǎn)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2 start-up and operation 2.1 啟動油泵,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)異常噪音和(hé)振(zhèn)動2.2 notice there is no abnormal noise and vibration 2.3 注意真空表讀數(shù),啟動後當壓力表及真空表的(de)讀數經過(guò)一段(duàn)時間的波動而(ér)時針穩定後,說明泵内已經上液,油泵竟如(rú)正常工作(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 在泵進入正常輸油作業前,應特别注意泵内油溫升高情況,如果這個過程長,泵内(nèi)油溫(wēn)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 如果泵内溫度過(guò)高而引起自吸困(kùn)難.可暫時(shí)停機(jī),利用出口管路中的(de)液(yè)體倒流或直(zhí)接向(xiàng)泵内補充液體,使泵内液體降溫,即可啟(qǐ)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(zhōng)因故停泵,需在(zài)啟動時,把出口控制閥稍開.這樣既有利于自(zì)吸過程中其他從吐出口排出,又能保證(zhèng)泵在較輕的(de)負(fù)荷下(xià)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)或每次使用前應檢查并及時補充(chōng)一次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 停車 3.1 關(guān)閉吐出(chū)管路上的閘閥 3.2 使泵停止轉動(dòng) 4 易損件的(de)維護 4.1 滾動軸承:當油泵長期運動後,油泵磨損到一定程度必須更換 4.2 前後密封環:當密封環磨損(sǔn)到一定程度時,須進行更換(huàn) 4.3 機械密封:在不漏油的情況下,一(yī)般不應拆開檢查,若(ruò)軸承體下端洩漏口處産生嚴重洩露時(shí),則應對機械密封進行拆檢.裝(zhuāng)拆機械密封時,必須輕取輕放,注意(yì)配(pèi)合面的清潔(jié),不好好動、靜環表面的光(guāng)潔度,嚴禁敲(qiāo)擊(jī)碰撞。
