石油瀝青(qing)asphalt 石油瀝青是原(yuán)油蒸餾後的殘(can)渣。根據提煉程(chéng)度的不同，在常(chang)溫下成液體、半(bàn)固體或固體。石(shí)油瀝青色黑而(ér)有光澤，具有較(jiào)高的感溫性。由(yóu)于它在生産過(guò)程中曾經蒸餾(liú)至400℃以上，因而所(suǒ)含揮發成分甚(shen)少，但仍可能有(you)高分子的碳氫(qing)化合物未經揮(hui)發出來，這些物(wù)質或多或少對(duì)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(qīng)Natural asphalt 天然瀝青儲藏(cáng)在地下，有的形(xing)成礦層或在地(dì)殼表面堆積。這(zhe)種瀝青大都經(jing)過天然蒸發、氧(yang)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. 瀝(lì)青材料分為地(dì)瀝青和焦油瀝(li)青兩大類。地瀝(li)青又分為天然(ran)瀝青和石油瀝(li)青，天然瀝青是(shì)石油滲出地表(biao)經長期暴露和(he)蒸發後的殘留(liu)物；石油瀝青是(shì)将精制加工石(shí)油所殘餘的渣(zha)油，經适當的工(gōng)藝處理後得到(dào)的産品。焦油瀝(li)青是煤、木材等(deng)有機物幹餾加(jia)工所得的焦油(yóu)經再加工後的(de)産品。工程中采(cǎi)用的瀝青絕大(dà)多數是石油瀝(lì)青，石油瀝青是(shì)複雜的碳氫化(huà)合物與其非金(jin)屬衍生物組成(chéng)的混合物。通常(chang)瀝青閃點在240℃~330℃之(zhi)間，燃點比閃點(dian)約高3℃~6℃度，因此施(shī)工溫度應控制(zhi)在閃點以下。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(shu)送改性瀝青泵(beng)在開始運轉前(qian)，往齒輪泵的殼(ké)體内灌滿待輸(shu)送的液體，便于(yú)安全啟動。若環(huan)境溫度低于冰(bīng)點，應預先向泵(bèng)内通入熱蒸汽(qi)，進行預熱處理(li)，然後才可啟動(dòng)齒輪泵。高粘度(du)泵的旋轉方向(xiàng)要與進、出油口(kou)相符。齒輪泵若(ruò)是第一次運行(háng)，或長期閑置後(hòu)再使用，最好在(zai)空載或小負荷(he)情況下先跑合(he)一小時左右。如(ru)果在跑合階段(duàn)預先覺察出異(yi)常溫升、洩漏、振(zhen)動和噪聲時，應(ying)停機檢查。高粘(zhān)度齒輪泵的支(zhi)座或法蘭與其(qí)驅動電機應采(cǎi)用共同的安裝(zhuāng)基礎，基礎、法蘭(lan)或支座均需具(jù)有足夠的剛度(dù)，以減小齒輪泵(bèng)運轉時産生的(de)振動和噪聲。電(dian)動機與齒輪泵(bèng)須用彈性聯軸(zhou)器連接，同軸度(du)小于0.1毫米，傾斜(xie)角不得大于1度(du)。安裝聯軸器時(shí)不得用錘敲打(dǎ)，以免傷害齒輪(lún)泵的齒輪等零(líng)件。若用帶輪、鍊(lian)輪等驅動時應(ying)設托架支承，以(yǐ)防主動齒輪軸(zhóu)承受徑向力。緊(jǐn)固齒輪泵、電動(dòng)機的地腳螺釘(ding)時，螺釘受力應(ying)均勻，連接可靠(kào)。用手轉動聯軸(zhou)器時，應感覺到(dao)齒輪泵能夠輕(qīng)松地轉動，沒有(yǒu)卡緊等異常現(xian)象出現，然後才(cai)可以配管。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(song)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(huo)急劇拐彎、減少(shao)彎頭，去除不必(bì)要的閥門、附件(jian)，盡可能地降低(di)泵的安裝高度(du)，縮短吸油管道(dào)的長度，以減少(shǎo)壓力損失。管接(jie)頭等元件的密(mi)封要良好，以防(fáng)止空氣侵入，從(cóng)而控制氣穴與(yu)氣蝕的發生。止(zhi)回閥與安全閥(fá)在齒輪泵的輸(shū)出管路上最好(hao)安裝一個止回(hui)閥。這樣在檢修(xiu)泵及輸出管道(dao)時，系統中的液(ye)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(dào)内産生局部真(zhen)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(dù)泵的出口管路(lù)上還應當設置(zhi)安全閥等保護(hù)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(fa)卸壓。安全閥可(ke)以與泵體或泵(bèng)蓋鑄成一體，也(ye)可以單獨裝配(pèi)。對于需要正反(fan)轉的高粘度齒(chi)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(ye)體的齒輪泵，應(ying)做到在較低的(de)功耗、較少的洩(xie)漏、較大的壓力(li)下輸出最多的(de)流量。在确定所(suo)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(bìng)注意考慮系統(tǒng)的工作溫度範(fan)圍。當希望在某(mou)一較寬的溫度(du)範圍内使用時(shí)，輸送介質的粘(zhan)度指數應該高(gao)些。輸送介質不(bu)僅是能量傳遞(dì)的中介，而且也(yě)是潤滑、密封及(jí)傳熱介質。液體(tǐ)粘度過高會增(zēng)加内摩擦阻力(lì)，降低輸出功率(lǜ)，浪費能量，并産(chǎn)生過高的系統(tong)溫度.高粘度齒(chǐ)輪泵的出口管(guan)路上應當設置(zhì)安全閥等保護(hù)裝置，這樣一旦(dàn)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(yao)正反轉的高粘(zhan)度齒輪泵，其進(jin)出口管路上均(jun)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(xuan)定1, select the work pressure 輸送改性瀝(lì)青泵額定的壓(yā)力是指泵連續(xù)工作時的最高(gāo)許用壓力，而其(qí)工作壓力則決(jué)定于外部負載(zai)，安裝和調試的(de)壽命與其工作(zuo)壓力直接相關(guan)。對于不頻繁工(gōng)作的齒輪泵，其(qí)工作壓力可取(qu)為泵的額定壓(ya)力，考慮到産品(pin)質量不同，最好(hao)将額定壓力降(jiàng)低20%～30%使用。對于經(jing)常工作于較高(gao)壓力下的齒輪(lun)泵，其工作壓力(li)應比泵的額定(dìng)壓力低1～2個壓力(lì)級。石油化工設(shè)備常常是24小時(shí)連續運轉，這時(shi)泵的工作壓力(li)應該取得比額(e)定壓力低得多(duo)，且工作轉速也(yě)應該低于額定(dìng)轉速。如果高粘(zhān)度齒輪泵的工(gong)作壓力調整過(guo)高，則會使齒輪(lún)泵在超負荷下(xia)運行。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. 輸送改性(xìng)瀝青泵的支座(zuo)或法蘭與其驅(qu)動電機應采用(yòng)共同的安裝基(ji)礎，基礎、法蘭或(huo)支座均需具有(you)足夠的剛度，以(yi)減小齒輪泵運(yun)轉時産生的振(zhen)動和噪聲。電動(dòng)機與齒輪泵須(xū)用彈性聯軸器(qì)連接，同軸度小(xiao)于0.1毫米，傾斜角(jiao)不得大于1度。安(ān)裝聯軸器時不(bu)得用錘敲打，以(yǐ)免傷害齒輪泵(beng)的齒輪等零件(jiàn)。若用帶輪、鍊輪(lún)等驅動時應設(she)托架支承，以防(fang)主動齒輪軸承(cheng)受徑向力。緊固(gù)齒輪泵、電動機(jī)的地腳螺釘時(shi)，螺釘受力應均(jun1)勻，連接可靠。用(yong)手轉動聯軸器(qì)時，應感覺到齒(chi)輪泵能夠輕松(song)地轉動，沒有卡(ka)緊等異常現象(xiang)出現，然後才可(ke)以配管。高粘度(dù)齒輪泵的吸油(yóu)管道内徑應足(zú)夠大，并避免狹(xiá)窄通道或急劇(ju)拐彎、彎頭，去除(chu)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(hǎo)，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(zhuǎn)前，往齒輪泵的(de)殼體内灌滿待(dai)輸送的液體，便(biàn)于安全動。若環(huán)境溫度低于冰(bing)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(bèng)的旋轉方向要(yào)與進、出油口相(xiàng)符。齒輪泵若是(shi)第一次運行，或(huò)長期閑置後再(zài)使用，最好在空(kong)載或小負荷情(qíng)況下先跑合一(yi)小時左右。如果(guo)在跑合階段預(yu)先覺出異常溫(wen)升、洩漏、振動和(hé)噪聲時，應機檢(jiǎn)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(zhi)，這樣一旦泵的(de)出口通道發生(sheng)堵塞，就可以打(da)開安全閥卸壓(yā)。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.
