壓路機發(fā)動機上的增壓器如何安全使用？

來源：http://www.lehuoaijia.com/ 日期：2023-03-01

為什么增壓器是壓路機發(fā)動機上容易出故障的總成？因為增壓器的額定工作轉速在每分鐘13萬轉以上，且處于排氣歧管出口處，溫度非常高（800℃以上），進、排氣壓力也較大，即高溫、高壓、高轉速，所以對增壓器的潤滑和冷卻及密封的要求比較高。為了保證增壓器的使用壽命，在設計上要保證對增壓器浮動軸承的潤滑和冷卻，同時濟南壓路機租賃人員認為，在使用中要求做到：

Why is the supercharger an assembly prone to failure on the engine of the road roller? Because the rated working speed of the supercharger is more than 130000 rpm, and it is at the outlet of the exhaust manifold, the temperature is very high (more than 800 ℃), and the inlet and exhaust pressures are also high, that is, high temperature, high pressure, high speed, so the requirements for lubrication, cooling and sealing of the supercharger are higher. In order to ensure the service life of the supercharger, the lubrication and cooling of the floating bearing of the supercharger should be guaranteed in the design. At the same time, the leasing personnel of Jinan roller believed that the following requirements should be met in the use:

①發(fā)動機起動后應怠速運轉3-5分鐘，不要立即加負荷，以保證增壓器的良好潤滑。主要原因是增壓器位于發(fā)動機的頂部，如果發(fā)動機起動后增壓器立即開始高速運轉，就會導致機油壓力未能及時升高給增壓器供油，造成增壓器缺油損壞，甚至燒壞整個增壓器。

① After the engine is started, it should run at idle speed for 3-5 minutes. Do not load it immediately to ensure the good lubrication of the supercharger. The main reason is that the supercharger is located on the top of the engine. If the supercharger starts to run at high speed immediately after the engine is started, the oil pressure will not rise in time to supply oil to the supercharger, causing the supercharger to be damaged due to lack of oil, and even burning the entire supercharger.

②怠速時間不宜過長，一般不超過10分鐘，怠速時間過長容易造成壓氣機端漏油。

② The idle time should not be too long, generally not more than 10 minutes, which is easy to cause oil leakage at the compressor end.

③停車前不要立即關閉發(fā)動機，應怠速3-5分鐘，以使增壓器轉速和排氣系統(tǒng)的溫度降下來，防止發(fā)生回熱—機油結焦—軸承燒損等故障。經常性的不正確使用會使增壓器損壞。

③ Do not shut down the engine immediately before stopping. Idle for 3-5 minutes to reduce the speed of the supercharger and the temperature of the exhaust system, and prevent the failure of heat regeneration - oil coking - bearing burning. Frequent incorrect use will damage the supercharger.

④長期未使用的發(fā)動機（一般超過7天），或新?lián)Q增壓器的發(fā)動機，在使用前應在增壓器的進油口加注機油，否則會因潤滑不良降低壽命或損壞增壓器。

④ The engine that has not been used for a long time (generally more than 7 days), or the engine with a new supercharger, should be filled with oil at the oil inlet of the supercharger before use, otherwise the life of the supercharger will be reduced or the supercharger will be damaged due to poor lubrication.

⑤定期檢查各連接部位是否有松動漏氣漏油現(xiàn)象，回油管是否通暢，如有應及時排除。

⑤ Regularly check whether there is looseness, air leakage and oil leakage at all connecting parts, and whether the oil return pipe is smooth. If any, it should be eliminated in time.

⑥保證空氣濾清器清潔，并按要求定期更換。

⑥ Ensure that the air filter is clean and replace it regularly as required.

⑦定期更換機油濾清器。

⑦ Replace the oil filter regularly.

⑧定期檢查增壓器軸的徑向軸向間隙，軸向間隙應不大于0.15毫米，徑向間隙為：葉輪與壓殼的間隙不小于0.10毫米，否則應請專門的人員維修，以免擴大損失。

⑧ Regularly check the radial and axial clearance of the supercharger shaft. The axial clearance should not be greater than 0.15 mm. The radial clearance is: the clearance between the impeller and the pressure housing should not be less than 0.10 mm. Otherwise, special personnel should be invited for maintenance to avoid expanding the loss.
