如何避免焦化發(fā)電機組過(guò)度磨損
焦化發(fā)電機組在一段時(shí)間的使用后難免會(huì )出現磨損現象，這是正?，F象。但是，如果出現不合理的過(guò)度磨損，這樣的情況就異常了?？赡苁怯捎谟脩?hù)的使用不當，也可能是由于機器發(fā)生了某些故障，因此，用戶(hù)應該要了解哪些因素會(huì )使得焦化發(fā)電機組磨損，才好對癥下藥避免其過(guò)度磨損的情況。
It is a normal phenomenon that the coking generator set will inevitably be worn after a period of use. However, if there is unreasonable excessive wear, such a situation is abnormal. It may be due to improper use of the user or some faults of the machine. Therefore, the user should know what factors will cause the coking generator set to wear, so as to suit the remedy to the case and avoid excessive wear.
燃料和潤滑油的質(zhì)量要和焦化機的結構相適應。焦化中若含有硫或其它雜質(zhì)時(shí)，在燃燒過(guò)程中便會(huì )產(chǎn)生酸類(lèi)和其它腐蝕性物質(zhì)，加速氣缸的磨損；焦化中重質(zhì)餾分過(guò)多，燃燒后便容易形成積炭，使活塞環(huán)與氣缸產(chǎn)生磨料磨損；
The quality of fuel and lubricating oil shall be compatible with the structure of coking machine. If sulfur or other impurities are contained in the coking process, acids and other corrosive substances will be produced during the combustion process, which will accelerate the wear of the cylinder; If there are too many heavy fractions in coking, carbon deposits will easily form after combustion, which will cause abrasive wear of piston rings and cylinders;
焦化粘度的大小對混合氣形成、供油設備工作可靠性都有影響。對潤滑油來(lái)說(shuō)，影響大的是粘度和抗氧化性，應根據焦化發(fā)電機組焦化機的工作條件合理選擇使用，切不可亂用。
The coking viscosity has an effect on the mixture formation and the working reliability of oil supply equipment. For lubricating oil, the viscosity and oxidation resistance are the most important factors. It should be reasonably selected and used according to the working conditions of the coking machine of the coking generator set, and must not be used indiscriminately.
試驗表明，焦化機的磨擦隨著(zhù)轉速和負荷的增加而增加。因為負荷增加時(shí)，磨擦表面上的單位壓力增加，熱狀況不良。當轉速增加時(shí)，單位時(shí)間內磨擦的次數半加，而在同一功率下，轉速增加比負荷增加時(shí)磨損要大。
The test shows that the friction of coking machine increases with the increase of rotating speed and load. Because when the load increases, the unit pressure on the friction surface increases and the thermal condition is poor. When the rotation speed increases, the number of friction per unit time increases by half, and at the same power, the wear is greater when the rotation speed increases than when the load increases.
但過(guò)低的轉速由于不能保證良好的液體潤滑條件，同樣使磨損增加。所以，對一定的焦化機來(lái)說(shuō)，有一個(gè)適合的工作轉速范圍。
However, too low a rotational speed can not guarantee good liquid lubrication conditions, which also increases wear. Therefore, for a certain coking machine, there is a suitable working speed range.
此外，焦化機經(jīng)常加速、減速、停車(chē)和起動(dòng)等不穩定工作時(shí)，由于轉速和負荷的頻繁變化，焦化機潤滑條件不良，熱狀態(tài)不穩定，磨損便增大。特別是在起動(dòng)時(shí)，曲軸轉速低，機油泵供油不及時(shí)，再加油溫低，機油粘度大，磨擦表面難以建立液體潤滑，磨損是很?chē)乐氐摹?/div>
In addition, when the coking machine often accelerates, decelerates, stops and starts, due to frequent changes in speed and load, the lubrication condition of the coking machine is poor, the thermal state is unstable, and the wear increases. Especially when starting, the crankshaft speed is low, the oil pump does not supply oil in time, the refuelling temperature is low, the oil viscosity is high, the friction surface is difficult to establish liquid lubrication, and the wear is very serious.
使用環(huán)境的氣溫對焦化發(fā)電機的磨損也是有影響的。氣溫高時(shí)發(fā)動(dòng)機易過(guò)熱，潤滑油粘度低，零件的磨損便增加。氣溫低時(shí)潤滑油粘度變大，焦化機起動(dòng)困難，工作時(shí)冷卻水不能保持正常溫度，增加零件的磨損和腐蝕。焦化機在低溫起動(dòng)時(shí)，磨損更為嚴重。更多注意事項就來(lái)我們網(wǎng)站http://m.elmasticar.com咨詢(xún)了解吧！
The temperature of the operating environment also has an impact on the wear of the coking generator. When the temperature is high, the engine is easy to overheat, the viscosity of lubricating oil is low, and the wear of parts will increase. When the temperature is low, the viscosity of lubricating oil becomes large, the coking machine is difficult to start, and the cooling water cannot maintain the normal temperature during operation, which increases the wear and corrosion of parts. When the coking machine is started at low temperature, the wear is more serious. More precautions come to our website http://m.elmasticar.com Consult and understand!
