煤焦瀝青是(shi)煉焦的副産(chǎn)品，即焦油蒸(zheng)餾後殘留在(zai)蒸餾釜内的(de)黑色物質。它(ta)與精制焦油(you)隻是物理性(xing)質有分别，沒(méi)有明顯的界(jiè)限，一般的劃(huà)分方法是規(gui)定軟化點在(zài)26．7℃（立方塊法）以(yǐ)下的為焦油(you)，26．7℃以上的為瀝(li)青。煤焦瀝青(qīng)中主要含有(yǒu)難揮發的蒽(ēn)、菲、芘等。這些(xie)物質具有毒(du)性，由于這些(xie)成分的含量(liang)不同，煤焦瀝(lì)青的性質也(yě)因而不同。溫(wen)度的變化對(duì)煤焦瀝青的(de)影響很大，冬(dōng)季容易脆裂(liè)，夏季容易軟(ruǎn)化。加熱時有(you)特殊氣味；加(jiā)熱到260℃在5小時(shí)以後，其所含(han)的蒽、菲、芘等(deng)成分就會揮(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(yóu)瀝青asphalt 天然(rán)瀝青Natural asphalt 天然瀝(li)青儲藏在地(dì)下，有的形成(chéng)礦層或在地(di)殼表面堆積(ji)。這種瀝青大(da)都經過天然(ran)蒸發、氧化，一(yī)般已不含有(you)任何毒素。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(li)青材料分為(wei)地瀝青和焦(jiao)油瀝青兩大(dà)類。地瀝青又(yòu)分為天然瀝(lì)青和石油瀝(lì)青，天然瀝青(qīng)是石油滲出(chū)地表經長期(qi)暴露和蒸發(fā)後的殘留物(wù)；石油瀝青是(shi)将精制加工(gōng)石油所殘餘(yú)的渣油，經适(shì)當的工藝處(chù)理後得到的(de)産品。焦油瀝(lì)青是煤、木材(cái)等有機物幹(gàn)餾加工所得(dé)的焦油經再(zai)加工後的産(chǎn)品。工程中采(cǎi)用的瀝青絕(jue)大多數是石(shí)油瀝青，石油(you)瀝青是複雜(za)的碳氫化合(he)物與其非金(jīn)屬衍生物組(zu)成的混合物(wù)。通常瀝青閃(shan)點在240℃~330℃之間，燃(rán)點比閃點約(yuē)高3℃~6℃度，因此施(shī)工溫度應控(kòng)制在閃點以(yǐ)下。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 輸送改性(xìng)瀝青泵在開(kāi)始運轉前，往(wǎng)齒輪泵的殼(ké)體内灌滿待(dài)輸送的液體(ti)，便于安全啟(qi)動。若環境溫(wēn)度低于冰點(diǎn)，應預先向泵(bèng)内通入熱蒸(zheng)汽，進行預熱(re)處理，然後才(cai)可啟動齒輪(lún)泵。高粘度泵(beng)的旋轉方向(xiàng)要與進、出油(yóu)口相符。齒輪(lún)泵若是第一(yī)次運行，或長(zhǎng)期閑置後再(zai)使用，最好在(zai)空載或小負(fu)荷情況下先(xian)跑合一小時(shi)左右。如果在(zài)跑合階段預(yù)先覺察出異(yi)常溫升、洩漏(lou)、振動和噪聲(shēng)時，應停機檢(jian)查。高粘度齒(chi)輪泵的支座(zuò)或法蘭與其(qí)驅動電機應(ying)采用共同的(de)安裝基礎，基(ji)礎、法蘭或支(zhi)座均需具有(yǒu)足夠的剛度(du)，以減小齒輪(lun)泵運轉時産(chan)生的振動和(he)噪聲。電動機(jī)與齒輪泵須(xu)用彈性聯軸(zhóu)器連接，同軸(zhou)度小于0.1毫米(mǐ)，傾斜角不得(de)大于1度。安裝(zhuang)聯軸器時不(bú)得用錘敲打(da)，以免傷害齒(chǐ)輪泵的齒輪(lun)等零件。若用(yong)帶輪、鍊輪等(děng)驅動時應設(she)托架支承，以(yǐ)防主動齒輪(lun)軸承受徑向(xiang)力。緊固齒輪(lún)泵、電動機的(de)地腳螺釘時(shí)，螺釘受力應(yīng)均勻，連接可(kě)靠。用手轉動(dong)聯軸器時，應(ying)感覺到齒輪(lun)泵能夠輕松(sōng)地轉動，沒有(you)卡緊等異常(chang)現象出現，然(rán)後才可以配(pei)管。High viscosity pump before starting work, to gear pump casing filled with liquid, facilitate safe launch.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.The direction of rotation of the pump with high viscosity, oil outlet in accord.Gear pump is the first run, or long-term idle before using, had better under the condition of no load or small load to run one hour or so.If in the running-in stage in advance detect abnormal temperature rise, leakage, vibration and noise, should stop check.High viscosity gear pump bearing or flange should adopt a common drive motor installationFoundation, foundation, flange or support all needs to have enough rigidity, to reduce the vibration of gear pump is running and noise.Motor and gear pump with elastic shaft coupling, coaxial degree is less than 0.1 mm, Angle shall not be greater than 1 degree.When installing coupling hammer shall not be used, in order to avoid damage of the gear pump gearAnd other parts.If use the belt wheel, wheel, etc, shall set bracket support, in case of driving gear bearing by the radial force.Ground screw fastening gear

1、工作壓(yā)力的選定1, select the work pressure 輸(shū)送改性瀝青(qing)泵額定的壓(ya)力是指泵連(lian)續工作時的(de)最高許用壓(ya)力，而其工作(zuò)壓力則決定(dìng)于外部負載(zai)，安裝和調試(shi)的壽命與其(qi)工作壓力直(zhi)接相關。對于(yú)不頻繁工作(zuo)的齒輪泵，其(qí)工作壓力可(kě)取為泵的額(é)定壓力，考慮(lü)到産品質量(liàng)不同，最好将(jiāng)額定壓力降(jiang)低20%～30%使用。對于(yu)經常工作于(yu)較高壓力下(xia)的齒輪泵，其(qi)工作壓力應(ying)比泵的額定(ding)壓力低1～2個壓(yā)力級。石油化(hua)工設備常常(cháng)是24小時連續(xu)運轉，這時泵(bèng)的工作壓力(li)應該取得比(bǐ)額定壓力低(di)得多，且工作(zuò)轉速也應該(gai)低于額定轉(zhuǎn)速。如果高粘(zhān)度齒輪泵的(de)工作壓力調(diào)整過高，則會(hui)使齒輪泵在(zài)超負荷下運(yùn)行。High viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.For not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.For often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.Petrochemical equipment are often 24 hours of continuous operation, and at this time of the pump working pressure should be obtained was much lower than the rated pressure, and the work speed should be lower than the rated speed.If the high viscosity gear pump high pressure adjustment, will make the pump running under overload. 2.安裝與試(shì)運轉2. Installation and commissioning 輸送改(gǎi)性瀝青泵的(de)支座或法蘭(lan)與其驅動電(diàn)機應采用共(gong)同的安裝基(ji)礎，基礎、法蘭(lan)或支座均需(xu)具有足夠的(de)剛度，以減小(xiao)齒輪泵運轉(zhuan)時産生的振(zhen)動和噪聲。電(dian)動機與齒輪(lun)泵須用彈性(xing)聯軸器連接(jie)，同軸度小于(yu)0.1毫米，傾斜角(jiao)不得大于1度(du)。安裝聯軸器(qi)時不得用錘(chui)敲打，以免傷(shāng)害齒輪泵的(de)齒輪等零件(jian)。若用帶輪、鍊(liàn)輪等驅動時(shi)應設托架支(zhī)承，以防主動(dong)齒輪軸承受(shòu)徑向力。緊固(gu)齒輪泵、電動(dong)機的地腳螺(luo)釘時，螺釘受(shòu)力應均勻，連(lián)接可靠。用手(shou)轉動聯軸器(qì)時，應感覺到(dao)齒輪泵能夠(gou)輕松地轉動(dong)，沒有卡緊等(děng)異常現象出(chū)現，然後才可(ke)以配管。高粘(zhān)度齒輪泵的(de)吸油管道内(nei)徑應足夠大(da)，并避免狹窄(zhai)通道或急劇(jù)拐彎、彎頭，去(qu)除不必要的(de)閥門、附件，盡(jìn)可能地降低(dī)泵的安裝高(gao)度，縮短吸油(yóu)管道的長度(du)，以減少壓力(lì)損失。管接頭(tóu)等元件的密(mì)封要良好，以(yi)防止空氣侵(qin)入，從而控制(zhi)氣穴與氣蝕(shi)的發生。在開(kai)始運轉前，往(wǎng)齒輪泵的殼(ké)體内灌滿待(dài)輸送的液體(tǐ)，便于安全動(dong)。若環境溫度(du)低于冰點，應(ying)預先向泵内(nei)通入熱蒸汽(qi)，進行預熱處(chù)理，然後才可(kě)啟動齒輪泵(bèng)。齒輪泵的旋(xuán)轉方向要與(yǔ)進、出油口相(xiang)符。齒輪泵若(ruò)是第一次運(yun)行，或長期閑(xian)置後再使用(yòng)，最好在空載(zai)或小負荷情(qing)況下先跑合(he)一小時左右(yòu)。如果在跑合(hé)階段預先覺(jiào)出異常溫升(sheng)、洩漏、振動和(he)噪聲時，應機(ji)檢查。高粘度(du)泵的出口管(guan)路上還應當(dang)設置安全閥(fá)等保護裝置(zhì)，這樣一旦泵(bèng)的出口通道(dao)發生堵塞，就(jiù)可以打開安(an)全閥卸壓。對(duì)于需要正反(fan)轉的高粘度(du)齒輪泵，其進(jìn)出口管路上(shang)均需設置安(an)全閥。High viscosity pump bearing or flange and its drive motor should use common installation basis, foundation, flange or support all needs to have enough rigidity, to reduce the vibration of gear pump is running and noise.Motor and gear pump with elastic shaft coupling, coaxial degree is less than 0.1 mm, Angle shall not be greater than 1 degree.When installing coupling hammer shall not be used, in order to avoid damage gear and other parts of the gear pump.If use the belt wheel, wheel, etc, shall set bracket support, in case of driving gear bearing by the radial force.Ground screw fastening gear pump, motor, screw force should be uniform, reliable connection.Turn the coupling with the hand, should feel can easily turn the gear pump, no abnormal phenomenon such as clamping, then can be piping.High viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp bend, bend, remove unnecessary valves, fittings, as much as possible to reduce the installation height of pump, shorten the length of the oil suction pipe, in order to reduce the pressure loss.Components, such as pipe joint sealed well, in order to prevent the air intrusion, thus control air-pocket and the occurrence of cavitation.Before starting operation, to gear pump casing filled with liquid, easy to safety.If the environment temperature is below freezing, should advance to pump into the hot steam, preheating treatment, and then to start the pump.Direction of rotation of the gear pump, oil outlet in accord.Gear pump is the first run, or long-term idle before using, had better under the condition of no load or small load to run one hour or so.If in the running-in stage in advance the abnormal temperature rise, leakage, vibration and noise, should machine inspection.High viscosity of the pump outlet pipe also shall set up relief valve or other protective device on the road, so that once the clogging pump export channels, can open the relief valve pressure relief.For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve.
