      瀝青(qīng)屬于憎(zēng)水性材(cái)料,它(tā)不透水,也(yě)幾乎(hū)不溶于水(shuǐ)、丙酮、乙(yǐ)醚(mí)、稀(xī)乙(yǐ)醇,溶于二(èr)硫化(huà)碳、四氯化碳、氫氧化鈉(nà)。瀝青及(jí)其(qí)煙(yān)氣對皮膚(fū)粘膜(mó)具有刺激(jī)性,有(yǒu)光毒作用和緻癌作用。我(wǒ)國三種主要瀝(lì)青的(de)毒(dú)性:煤焦(jiāo)瀝青(qīng)>頁岩(yán)瀝青(qīng)>石油(yóu)瀝(lì)青(qīng),前二(èr)者有(yǒu)緻癌(ái)性。瀝青的(de)主要皮膚損害有(yǒu):光(guāng)毒性(xìng)皮炎,皮損限于面、頸部等暴露(lù)部分(fèn);黑變病,皮損常(cháng)對稱分布于(yú)暴(bào)露部(bù)位,呈(chéng)片狀,呈褐(hè)-深褐-褐黑色(sè);職業性痤瘡;疣狀(zhuàng)贅生(shēng)物及(jí)事故(gù)引起(qǐ)的熱燒(shāo)傷。此外(wài),尚有(yǒu)頭昏(hūn)、頭(tóu)脹(zhàng),頭痛、胸悶、乏力、惡心、食欲不振等全身(shēn)症(zhèng)狀和(hé)眼 、鼻、咽部的刺(cì)激症(zhèng)狀。asphalt is hydrophobic material, it impermeable, almost insoluble in water, dilute ethanol, acetone, ether, soluble in carbon disulfide, carbon tetrachloride, sodium hydroxide.asphalt and flue gas of skin mucous membrane irritation, has the light effect and the effect that cause cancer.china's three major asphalt toxicity: coal tar > > oil shale asphalt asphalt, before both have carcinogenicity.the main skin lesions are: asphalt light contact dermatitis, skin confined to the face, neck and other exposed parts;melanosis, skin lesions often symmetrical distributed in the exposed parts, plate shaped, brown - deep brown - brown-black;occupational acne;verrucous vegetations and the accident cause thermal burns.in addition, there are dizziness, head bilges, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptom and eye, nose, pharynx and irritation.
    煤焦瀝(lì)青coal tar
    煤焦瀝青是(shì)煉焦的(de)副(fù)産品,即焦(jiāo)油蒸(zhēng)餾後(hòu)殘留(liú)在蒸(zhēng)餾釜(fǔ)内的黑色物質(zhì)。它與精制(zhì)焦油隻是(shì)物(wù)理性質(zhì)有分(fèn)别,沒(méi)有明(míng)顯的(de)界限,一般(bān)的劃(huà)分方法是規定(dìng)軟化點在(zài)26.7℃(立方塊(kuài)法)以下(xià)的為(wéi)焦油,26.7℃以上(shàng)的為瀝(lì)青(qīng)。煤焦(jiāo)瀝青中主要含(hán)有難揮(huī)發(fā)的蒽(ēn)、菲、芘(pí)等。這些物(wù)質具(jù)有(yǒu)毒性,由(yóu)于這(zhè)些成分的(de)含量不同,煤焦瀝青(qīng)的性(xìng)質也因而不同(tóng)。溫度的變(biàn)化對煤焦(jiāo)瀝青的(de)影響很(hěn)大,冬季(jì)容易脆(cuì)裂,夏季容(róng)易軟(ruǎn)化。加熱(rè)時有特(tè)殊氣味;加熱到(dào)260℃在5小(xiǎo)時以(yǐ)後,其(qí)所含的蒽、菲、芘等成分(fèn)就會揮(huī)發出來。coal tar is a by-product of coking, namely tar distillation residue in distillation kettle black material.it has respectively with refined tar is only physical properties, there is no clear boundaries, is the way of dividing rules softening point in commonly 26.7 ℃ (cube method) for tar, under 26.7 ℃ above for asphalt.coal tar mainly contains difficult volatilization of anthracene, phenanthrene, pyrene, etc.these substances have toxic, because the content of these compounds is different, the properties of coal tar are so different.the change of temperature has much effect on the coal tar, winter easy embrittlement, summer is easy to soften.heating from time to tome special smell;heated to 260 ℃ after 5 hours, its composition such as anthracene, phenanthrene, pyrene will evaporate.
    石油瀝青asphalt
 
    石油(yóu)瀝(lì)青是(shì)原油蒸餾(liú)後的(de)殘渣。根據提煉(liàn)程度的不(bú)同,在(zài)常溫下成液體、半固(gù)體或(huò)固體(tǐ)。石油瀝青(qīng)色黑(hēi)而有光澤,具有(yǒu)較高(gāo)的感溫性(xìng)。由于它在(zài)生産(chǎn)過程(chéng)中曾經蒸(zhēng)餾至400℃以(yǐ)上,因而所含(hán)揮發成分(fèn)甚少,但(dàn)仍可能(néng)有高(gāo)分子(zǐ)的碳(tàn)氫化合物未經(jīng)揮發出來,這些(xiē)物質(zhì)或多(duō)或(huò)少對人(rén)體健(jiàn)康是(shì)有害的。petroleum asphalt is after crude distillation residue.depending on the degree of refining, into a liquid, semi-solid or solid at room temperature.petroleum pitch dark and luster, has higher heat resistance.because it had distillation in the production process to more than 400 ℃, thus contained little volatile component, but may still have high polymer without volatile hydrocarbons, which more or less is harmful to human health.
    天(tiān)然瀝(lì)青natural asphalt
 
    天(tiān)然(rán)瀝青儲(chǔ)藏在地下(xià),有的(de)形成(chéng)礦層或(huò)在(zài)地殼(ké)表(biǎo)面(miàn)堆積(jī)。這種瀝(lì)青(qīng)大都經過天然蒸發(fā)、氧化(huà),一般(bān)已不(bú)含有任何(hé)毒(dú)素(sù)。natural asphalt storage in underground, some forming seam or piled up in the earth's crust surface.the asphalt mostly through the natural evaporation and oxidation, generally do not contain any poison.

瀝青材(cái)料分為(wéi)地瀝青(qīng)和(hé)焦油(yóu)瀝青兩大類。地(dì)瀝青又分為天然瀝(lì)青和(hé)石油(yóu)瀝青,天然(rán)瀝青(qīng)是石油滲出地(dì)表經(jīng)長(zhǎng)期(qī)暴露(lù)和蒸發後的殘(cán)留物;石油瀝青是将精制(zhì)加工(gōng)石油所殘(cán)餘的渣油,經适當的工藝處理後得(dé)到的産品(pǐn)。焦油(yóu)瀝青(qīng)是煤、木材(cái)等有機物幹餾(liú)加工(gōng)所得(dé)的焦油(yóu)經(jīng)再加工後(hòu)的産(chǎn)品(pǐn)。工程中采用的瀝青絕(jué)大多數是(shì)石油瀝青(qīng),石(shí)油瀝青(qīng)是複雜的碳氫(qīng)化合物(wù)與其非(fēi)金屬(shǔ)衍(yǎn)生(shēng)物組(zǔ)成的混(hùn)合物。通常瀝青閃點在(zài)240℃~330℃之間,燃點(diǎn)比閃(shǎn)點約(yuē)高3℃~6℃度(dù),因此(cǐ)施工(gōng)溫度應控(kòng)制在閃點(diǎn)以下(xià)。asphalt material divided into two categories, pitch and bitumen.asphalt is divided into natural asphalt and petroleum asphalt, natural bitumen is oil seepage surface after long exposure and evaporation residue;petroleum asphalt is a residual of residual oil will be refined processing, after appropriate processing products.bitumen is coal, wood and other organic matter carbonization processing tar after reprocessing of products.engineering used in the asphalt is the vast majority of asphalt, asphalt is a complex mixture of hydrocarbons with nonmetal derivatives.usually asphalt flash point between 240 ℃ ~ 330 ℃, flash point is higher than flash point about 3 ℃ ~ 6 ℃ degrees, so the construction temperature should be controlled below the flash point.v  瀝青(qīng)輸送泵是(shì)容(róng)積式内齧合(hé)齒輪(lún)泵,主動齒(chǐ)輪(外轉子(zǐ))帶動被動(dòng)齒輪(lún)(内轉(zhuǎn)子)旋轉時(shí),不斷産生封閉(bì)的空間,在(zài)吸油區齒輪逐漸脫(tuō)離齧合(hé)而(ér)液體(tǐ)不斷(duàn)地充滿齒(chǐ)間并被帶(dài)到出(chū)油區,齒輪(lún)在(zài)出(chū)油區進入(rù)齧合(hé)時液(yè)體被排出(chū)。兩個旋轉(zhuǎn)齒輪(lún)的(de)共同作用,形(xíng)成一個穩(wěn)定的(de)體積排量,沒有(yǒu)脈動。由于(yú)泵是完全(quán)對(duì)稱的,泵(bèng)可以反轉(zhuǎn),液流(liú)方向也随之(zhī)改(gǎi)變。但應注(zhù)意,泵(bèng)的轉(zhuǎn)向可能受(shòu)到密(mì)封或(huò)泵内其它結構的限(xiàn)制,用戶有反轉(zhuǎn)要求時應在訂(dìng)貨時(shí)做出(chū)說明。
     該泵的流(liú)量可根據液體(tǐ)粘度選擇合适(shì)的轉速來(lái)調整(zhěng)。由于(yú)泵(bèng)的流量(liàng)取決(jué)于單(dān)轉排(pái)量和旋轉速度(dù),單轉(zhuǎn)排(pái)量(liàng)是(shì)泵(bèng)軸旋(xuán)轉360度(dù)的體積(jī)排量,實(shí)際上,單轉排量(liàng)是在進出口壓(yā)差為(wéi)零(líng)時泵轉(zhuǎn)一周的(de)流量。各(gè)種規格的泵因為幾何尺寸已(yǐ)定,隻有通(tōng)過改(gǎi)變轉速來(lái)調整(zhěng)流量。轉速可由(yóu)改變馬(mǎ)達的轉(zhuǎn)速或(huò)減速機的(de)速比而改(gǎi)變,也可用變(biàn)速馬達(dá)或可變速(sù)減速機。

該泵結(jié)構簡(jiǎn)單,适用範圍(wéi)廣,可以輸送(sòng)高粘度和低粘(zhān)度的各種液體(tǐ),最高輸送(sòng)粘度可達(dá)500000cst。溫度(dù)範圍自-40—300,輸(shū)送液體可(kě)有潤滑(huá)性(xìng)也可(kě)以沒有(yǒu)潤滑性(xìng)。由于内外(wài)轉子齒數(shù)互為質數(shù),任意兩(liǎng)齒(chǐ)之間的機會相等,因(yīn)此齒的磨(mó)損非常均勻。
     
瀝(lì)青輸(shū)送泵(bèng)采用(yòng)模塊化設計,可(kě)根據不同的使用要求更換不(bú)同部件。可(kě)選夾(jiá)層結構,以方便(biàn)對泵加熱(rè)或冷(lěng)卻,可以選擇是(shì)否帶安全閥,可(kě)以選擇(zé)不同的密封(fēng)形式(shì),詳見密封結構圖。泵(bèng)的各個零件可以選用不(bú)同的(de)材質(zhì)以适應具(jù)體使(shǐ)用要求。

        不同的使用(yòng)條件,泵的(de)結構(gòu)形式可(kě)能不同,具體應(yīng)用請向廠家(jiā)或(huò)本公司(sī)客戶代表咨詢(xún)。需要指出的是泵的轉(zhuǎn)速愈高(gāo),泵的磨損愈嚴重,液體中如含(hán)有磨料物(wù)質,泵的材料應(yīng)選用(yòng)耐磨材(cái)質,在此(cǐ)種工(gōng)況下,泵的(de)壓力和轉速都應降低(dī),高溫條件下,則應增加泵的(de)間隙(xì),并采(cǎi)用耐(nài)熱(rè)材料
