煤焦瀝青是(shì)煉焦的副産品，即(jí)焦油蒸餾後殘留(liú)在蒸餾釜内的黑(hēi)色物質。它與精制(zhi)焦油隻是物理性(xìng)質有分别，沒有明(míng)顯的界限，一般的(de)劃分方法是規定(dìng)軟化點在26．7℃（立方塊(kuài)法）以下的為焦油(yóu)，26．7℃以上的為瀝青。煤(mei)焦瀝青中主要含(han)有難揮發的蒽、菲(fēi)、芘等。這些物質具(jù)有毒性，由于這些(xie)成分的含量不同(tóng)，煤焦瀝青的性質(zhì)也因而不同。溫度(dù)的變化對煤焦瀝(li)青的影響很大，冬(dong)季容易脆裂，夏季(jì)容易軟化。加熱時(shí)有特殊氣味；加熱(re)到260℃在5小時以後，其(qí)所含的蒽、菲、芘等(deng)成分就會揮發出(chu)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)瀝青是原油蒸餾(liu)後的殘渣。根據提(tí)煉程度的不同，在(zai)常溫下成液體、半(bàn)固體或固體。石油(you)瀝青色黑而有光(guāng)澤，具有較高的感(gǎn)溫性。由于它在生(shēng)産過程中曾經蒸(zhēng)餾至400℃以上，因而所(suǒ)含揮發成分甚少(shao)，但仍可能有高分(fen)子的碳氫化合物(wù)未經揮發出來，這(zhe)些物質或多或少(shao)對人體健康是有(you)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. 天然瀝青Natural asphalt 天(tiān)然瀝青儲藏在地(dì)下，有的形成礦層(céng)或在地殼表面堆(duī)積。這種瀝青大都(dōu)經過天然蒸發、氧(yang)化，一般已不含有(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. 輸送改性瀝青泵(bèng)在開始運轉前，往(wǎng)齒輪泵的殼體内(nei)灌滿待輸送的液(yè)體，便于安全啟動(dong)。若環境溫度低于(yu)冰點，應預先向泵(bèng)内通入熱蒸汽，進(jìn)行預熱處理，然後(hou)才可啟動齒輪泵(bèng)。高粘度泵的旋轉(zhuan)方向要與進、出油(you)口相符。齒輪泵若(ruo)是第一次運行，或(huò)長期閑置後再使(shǐ)用，最好在空載或(huò)小負荷情況下先(xiān)跑合一小時左右(you)。如果在跑合階段(duàn)預先覺察出異常(chang)溫升、洩漏、振動和(hé)噪聲時，應停機檢(jian)查。高粘度齒輪泵(beng)的支座或法蘭與(yu)其驅動電機應采(cǎi)用共同的安裝基(ji)礎，基礎、法蘭或支(zhi)座均需具有足夠(gou)的剛度，以減小齒(chǐ)輪泵運轉時産生(sheng)的振動和噪聲。電(diàn)動機與齒輪泵須(xū)用彈性聯軸器連(lian)接，同軸度小于0.1毫(háo)米，傾斜角不得大(da)于1度。安裝聯軸器(qi)時不得用錘敲打(da)，以免傷害齒輪泵(bèng)的齒輪等零件。若(ruo)用帶輪、鍊輪等驅(qū)動時應設托架支(zhi)承，以防主動齒輪(lún)軸承受徑向力。緊(jǐn)固齒輪泵、電動機(jī)的地腳螺釘時，螺(luó)釘受力應均勻，連(lian)接可靠。用手轉動(dong)聯軸器時，應感覺(jiao)到齒輪泵能夠輕(qīng)松地轉動，沒有卡(ka)緊等異常現象出(chū)現，然後才可以配(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 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. 輸送改性瀝青(qing)泵的吸油管道内(nèi)徑應足夠大，并避(bì)免狹窄通道或急(ji)劇拐彎、減少彎頭(tou)，去除不必要的閥(fá)門、附件，盡可能地(dì)降低泵的安裝高(gao)度，縮短吸油管道(dao)的長度，以減少壓(yā)力損失。管接頭等(děng)元件的密封要良(liáng)好，以防止空氣侵(qīn)入，從而控制氣穴(xué)與氣蝕的發生。止(zhi)回閥與安全閥在(zài)齒輪泵的輸出管(guǎn)路上最好安裝一(yi)個止回閥。這樣在(zai)檢修泵及輸出管(guǎn)道時，系統中的液(ye)體不會發生倒流(liu)。齒輪泵帶負荷停(tíng)車時，亦可防止泵(bèng)倒轉而在其輸出(chū)管道内産生局部(bù)真空。應當注意，出(chu)口止回閥不能裝(zhuang)反或出現卡死現(xian)象。高粘度泵的出(chū)口管路上還應當(dang)設置安全閥等保(bao)護裝置，這樣一旦(dan)泵的出口通道發(fā)生堵塞，就可以打(da)開安全閥卸壓。安(ān)全閥可以與泵體(tǐ)或泵蓋鑄成一體(tǐ)，也可以單獨裝配(pei)。對于需要正反轉(zhuan)的高粘度齒輪泵(bèng)，其進出口管路上(shàng)均需設置安全閥(fá)。High viscosity gear pump oil suction pipe diameter should be large enough, and to avoid the narrow channel, or a sharp turn, reducing elbow, 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.Check valve and relief valve on the output of the gear pump tube had better install a check valve.In the overhaul pump and output pipe, the system of fluid backflow will not occur.Gear pump to stop loading machine, can be in the output pipe to prevent pump reverse, and create a partial vacuum.It should be noted that the outlet check valve cannot be installed backwards or stuck.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.The relief valve can be cast and pump body and pump cover, also can separate assembly.For high viscosity gear pump need positive &negative, import and export all needs to set up the line safety valve. 輸送改性瀝青泵(beng)是輸送高粘度液(ye)體的齒輪泵，應做(zuo)到在較低的功耗(hào)、較少的洩漏、較大(da)的壓力下輸出最(zui)多的流量。在确定(dìng)所要輸送的介質(zhì)時，應該嚴格遵循(xún)産品說明書上的(de)規定，盡量使用廠(chǎng)家推薦的流體介(jiè)質，并注意考慮系(xì)統的工作溫度範(fan)圍。當希望在某一(yī)較寬的溫度範圍(wei)内使用時，輸送介(jiè)質的粘度指數應(ying)該高些。輸送介質(zhi)不僅是能量傳遞(di)的中介，而且也是(shi)潤滑、密封及傳熱(rè)介質。液體粘度過(guò)高會增加内摩擦(ca)阻力，降低輸出功(gōng)率，浪費能量，并産(chan)生過高的系統溫(wen)度.高粘度齒輪泵(beng)的出口管路上應(ying)當設置安全閥等(deng)保護裝置，這樣一(yi)旦泵的出口通道(dao)發生堵塞，就可以(yǐ)打開安全閥卸壓(ya)。對于需要正反轉(zhuǎn)的高粘度齒輪泵(bèng)，其進出口管路上(shang)均需設置安全閥(fa)。High viscosity pump is conveying liquid with high viscosity gear pump, should be in lower power consumption, less leakage, under the pressure of large output the most traffic.When determining to conveying medium, we should strictly follow the provisions of the product manuals on use manufacturers recommend fluid as far as possible, and pay attention to consider the system operating temperature range.When you want to use in a wide temperature range, medium viscosity index should be higher.Medium is not only the energy transfer intermediary, but also lubrication, sealing and heat transfer medium.Liquid viscosity is too high will increase internal friction resistance, lower output power, waste of energy, and generate high temperature system. High viscosity gear pump outlet pipe shall set up relief valve or other protective device on the road, so 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. 1、工作壓力的選定(dìng)1, select the work pressure 輸送改性瀝青泵(beng)額定的壓力是指(zhi)泵連續工作時的(de)最高許用壓力，而(er)其工作壓力則決(jué)定于外部負載，安(ān)裝和調試的壽命(ming)與其工作壓力直(zhí)接相關。對于不頻(pín)繁工作的齒輪泵(bèng)，其工作壓力可取(qǔ)為泵的額定壓力(li)，考慮到産品質量(liàng)不同，最好将額定(ding)壓力降低20%～30%使用。對(dui)于經常工作于較(jiao)高壓力下的齒輪(lun)泵，其工作壓力應(ying)比泵的額定壓力(li)低1～2個壓力級。石油(you)化工設備常常是(shì)24小時連續運轉，這(zhe)時泵的工作壓力(li)應該取得比額定(ding)壓力低得多，且工(gōng)作轉速也應該低(dī)于額定轉速。如果(guǒ)高粘度齒輪泵的(de)工作壓力調整過(guò)高，則會使齒輪泵(beng)在超負荷下運行(hang)。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.安裝與試運轉2. Installation and commissioning 輸(shū)送改性瀝青泵的(de)支座或法蘭與其(qí)驅動電機應采用(yong)共同的安裝基礎(chǔ)，基礎、法蘭或支座(zuo)均需具有足夠的(de)剛度，以減小齒輪(lún)泵運轉時産生的(de)振動和噪聲。電動(dòng)機與齒輪泵須用(yong)彈性聯軸器連接(jie)，同軸度小于0.1毫米(mǐ)，傾斜角不得大于(yú)1度。安裝聯軸器時(shi)不得用錘敲打，以(yǐ)免傷害齒輪泵的(de)齒輪等零件。若用(yòng)帶輪、鍊輪等驅動(dòng)時應設托架支承(chéng)，以防主動齒輪軸(zhóu)承受徑向力。緊固(gu)齒輪泵、電動機的(de)地腳螺釘時，螺釘(dìng)受力應均勻，連接(jie)可靠。用手轉動聯(lian)軸器時，應感覺到(dao)齒輪泵能夠輕松(sōng)地轉動，沒有卡緊(jin)等異常現象出現(xian)，然後才可以配管(guǎn)。高粘度齒輪泵的(de)吸油管道内徑應(yīng)足夠大，并避免狹(xia)窄通道或急劇拐(guǎi)彎、彎頭，去除不必(bi)要的閥門、附件，盡(jìn)可能地降低泵的(de)安裝高度，縮短吸(xī)油管道的長度，以(yǐ)減少壓力損失。管(guǎn)接頭等元件的密(mì)封要良好，以防止(zhǐ)空氣侵入，從而控(kòng)制氣穴與氣蝕的(de)發生。在開始運轉(zhuan)前，往齒輪泵的殼(ke)體内灌滿待輸送(song)的液體，便于安全(quan)動。若環境溫度低(dī)于冰點，應預先向(xiang)泵内通入熱蒸汽(qi)，進行預熱處理，然(rán)後才可啟動齒輪(lún)泵。齒輪泵的旋轉(zhuǎn)方向要與進、出油(yóu)口相符。齒輪泵若(ruò)是第一次運行，或(huo)長期閑置後再使(shi)用，最好在空載或(huo)小負荷情況下先(xiān)跑合一小時左右(yòu)。如果在跑合階段(duàn)預先覺出異常溫(wen)升、洩漏、振動和噪(zào)聲時，應機檢查。高(gāo)粘度泵的出口管(guan)路上還應當設置(zhì)安全閥等保護裝(zhuang)置，這樣一旦泵的(de)出口通道發生堵(dǔ)塞，就可以打開安(ān)全閥卸壓。對于需(xū)要正反轉的高粘(zhān)度齒輪泵，其進出(chu)口管路上均需設(shè)置安全閥。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.
