煤焦瀝青是煉(liàn)焦的副産品，即(ji)焦油蒸餾後殘(cán)留在蒸餾釜内(nèi)的黑色物質。它(ta)與精制焦油隻(zhī)是物理性質有(you)分别，沒有明顯(xian)的界限，一般的(de)劃分方法是規(gui)定軟化點在26．7℃（立(lì)方塊法）以下的(de)為焦油，26．7℃以上的(de)為瀝青。煤焦瀝(li)青中主要含有(you)難揮發的蒽、菲(fēi)、芘等。這些物質(zhi)具有毒性，由于(yú)這些成分的含(han)量不同，煤焦瀝(li)青的性質也因(yīn)而不同。溫度的(de)變化對煤焦瀝(lì)青的影響很大(dà)，冬季容易脆裂(liè)，夏季容易軟化(huà)。加熱時有特殊(shū)氣味；加熱到260℃在(zai)5小時以後，其所(suo)含的蒽、菲、芘等(deng)成分就會揮發(fā)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(qing)asphalt 天然瀝青(qīng)Natural asphalt 天然瀝青儲藏(cang)在地下，有的形(xíng)成礦層或在地(dì)殼表面堆積。這(zhe)種瀝青大都經(jīng)過天然蒸發、氧(yǎng)化，一般已不含(han)有任何毒素。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(sòng)改性瀝青泵的(de)吸油管道内徑(jìng)應足夠大，并避(bi)免狹窄通道或(huò)急劇拐彎、減少(shao)彎頭，去除不必(bi)要的閥門、附件(jiàn)，盡可能地降低(dī)泵的安裝高度(dù)，縮短吸油管道(dào)的長度，以減少(shao)壓力損失。管接(jie)頭等元件的密(mì)封要良好，以防(fang)止空氣侵入，從(cong)而控制氣穴與(yǔ)氣蝕的發生。止(zhǐ)回閥與安全閥(fá)在齒輪泵的輸(shū)出管路上最好(hǎo)安裝一個止回(huí)閥。這樣在檢修(xiū)泵及輸出管道(dao)時，系統中的液(yè)體不會發生倒(dǎo)流。齒輪泵帶負(fù)荷停車時，亦可(ke)防止泵倒轉而(er)在其輸出管道(dao)内産生局部真(zhēn)空。應當注意，出(chū)口止回閥不能(neng)裝反或出現卡(kǎ)死現象。高粘度(du)泵的出口管路(lu)上還應當設置(zhi)安全閥等保護(hu)裝置，這樣一旦(dan)泵的出口通道(dào)發生堵塞，就可(kě)以打開安全閥(fá)卸壓。安全閥可(kě)以與泵體或泵(beng)蓋鑄成一體，也(ye)可以單獨裝配(pei)。對于需要正反(fan)轉的高粘度齒(chǐ)輪泵，其進出口(kǒu)管路上均需設(she)置安全閥。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(sòng)改性瀝青泵是(shi)輸送高粘度液(yè)體的齒輪泵，應(yīng)做到在較低的(de)功耗、較少的洩(xiè)漏、較大的壓力(li)下輸出最多的(de)流量。在确定所(suǒ)要輸送的介質(zhì)時，應該嚴格遵(zun)循産品說明書(shū)上的規定，盡量(liàng)使用廠家推薦(jian)的流體介質，并(bing)注意考慮系統(tǒng)的工作溫度範(fàn)圍。當希望在某(mou)一較寬的溫度(dù)範圍内使用時(shí)，輸送介質的粘(zhān)度指數應該高(gao)些。輸送介質不(bú)僅是能量傳遞(di)的中介，而且也(yě)是潤滑、密封及(jí)傳熱介質。液體(ti)粘度過高會增(zeng)加内摩擦阻力(li)，降低輸出功率(lü)，浪費能量，并産(chan)生過高的系統(tǒng)溫度.高粘度齒(chǐ)輪泵的出口管(guǎn)路上應當設置(zhi)安全閥等保護(hu)裝置，這樣一旦(dan)泵的出口通道(dào)發生堵塞，就可(ke)以打開安全閥(fá)卸壓。對于需要(yào)正反轉的高粘(zhān)度齒輪泵，其進(jìn)出口管路上均(jun1)需設置安全閥(fá)。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(xuan)定1, select the work pressure 2.安裝與試(shì)運轉2. Installation and commissioning 輸送改性(xing)瀝青泵的支座(zuo)或法蘭與其驅(qū)動電機應采用(yong)共同的安裝基(jī)礎，基礎、法蘭或(huo)支座均需具有(you)足夠的剛度，以(yǐ)減小齒輪泵運(yùn)轉時産生的振(zhen)動和噪聲。電動(dong)機與齒輪泵須(xū)用彈性聯軸器(qì)連接，同軸度小(xiǎo)于0.1毫米，傾斜角(jiao)不得大于1度。安(an)裝聯軸器時不(bu)得用錘敲打，以(yǐ)免傷害齒輪泵(bèng)的齒輪等零件(jian)。若用帶輪、鍊輪(lun)等驅動時應設(shè)托架支承，以防(fáng)主動齒輪軸承(chéng)受徑向力。緊固(gu)齒輪泵、電動機(jī)的地腳螺釘時(shí)，螺釘受力應均(jun1)勻，連接可靠。用(yong)手轉動聯軸器(qi)時，應感覺到齒(chi)輪泵能夠輕松(sōng)地轉動，沒有卡(ka)緊等異常現象(xiàng)出現，然後才可(kě)以配管。高粘度(dù)齒輪泵的吸油(yóu)管道内徑應足(zu)夠大，并避免狹(xiá)窄通道或急劇(ju)拐彎、彎頭，去除(chú)不必要的閥門(men)、附件，盡可能地(dì)降低泵的安裝(zhuang)高度，縮短吸油(yóu)管道的長度，以(yǐ)減少壓力損失(shī)。管接頭等元件(jian)的密封要良好(hao)，以防止空氣侵(qin)入，從而控制氣(qi)穴與氣蝕的發(fa)生。在開始運轉(zhuan)前，往齒輪泵的(de)殼體内灌滿待(dai)輸送的液體，便(bian)于安全動。若環(huan)境溫度低于冰(bīng)點，應預先向泵(beng)内通入熱蒸汽(qi)，進行預熱處理(li)，然後才可啟動(dòng)齒輪泵。齒輪泵(beng)的旋轉方向要(yào)與進、出油口相(xiang)符。齒輪泵若是(shì)第一次運行，或(huo)長期閑置後再(zai)使用，最好在空(kong)載或小負荷情(qing)況下先跑合一(yī)小時左右。如果(guo)在跑合階段預(yù)先覺出異常溫(wēn)升、洩漏、振動和(hé)噪聲時，應機檢(jian)查。高粘度泵的(de)出口管路上還(hái)應當設置安全(quan)閥等保護裝置(zhì)，這樣一旦泵的(de)出口通道發生(shēng)堵塞，就可以打(da)開安全閥卸壓(ya)。對于需要正反(fǎn)轉的高粘度齒(chǐ)輪泵，其進出口(kou)管路上均需設(she)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.
