攪拌一體車(chē)潤滑系正常工作時(shí)，機油不斷地在一體車(chē)發(fā)動(dòng)機內循環(huán)流動(dòng)，對各運動(dòng)摩擦表面進(jìn)行強制潤滑，并從各摩擦表面帶走磨屑和摩擦熱，由于有效地向缸壁飛濺，保證了活塞環(huán)和缸壁在高溫高壓下的密封性和潤滑作用。你知道機油變質(zhì)的原因主要有幾點(diǎn)嗎？

When the lubrication system of the agitator truck works normally, the engine oil continuously circulates in the engine of the truck, forcibly lubricates the moving friction surfaces, and takes away the wear debris and friction heat from the friction surfaces. Due to the effective splash to the cylinder wall, the sealing and lubrication of the piston ring and cylinder wall under high temperature and pressure are ensured. Do you know the main reasons for oil deterioration?

攪拌一體車(chē)發(fā)動(dòng)機所裝用的離心式機油濾清器和全流式紙質(zhì)機油濾清器，較好地維持著(zhù)機油的良好品質(zhì)，但是隨著(zhù)車(chē)輛行駛里程的增加，一體車(chē)發(fā)動(dòng)機機油濾清器的過(guò)濾能力逐漸降低，積聚在潤滑油里的沒(méi)有燃燒過(guò)的燃料、水、燃燒生成物(如積碳、焦炭)、潤滑油的氧化生成物(膠質(zhì)、瀝青、各種酸等)、砂粒、灰塵、黑色及有色金屬磨損的顆粒愈來(lái)愈多。

The centrifugal oil filter and full flow paper oil filter installed in the engine of the agitator integrated vehicle maintain the good quality of the engine oil. However, with the increase of the vehicle mileage, the filtering capacity of the engine oil filter of the integrated vehicle gradually decreases, and the unburned fuel, water, combustion products (such as carbon deposit and coke), oxidation products of lubricating oil (gum, asphalt, various acids, etc.) Sand, dust, black and non-ferrous metal wear particles are more and more.

沉積在燃燒室和活塞頂部的膠質(zhì)，能形成積碳而引起一體車(chē)發(fā)動(dòng)機不正常燃燒;活塞環(huán)、氣門(mén)桿上有膠質(zhì)，會(huì )使這些零件咬死粘住，加劇了一體車(chē)發(fā)動(dòng)機各部件的磨損。

The gum deposited on the combustion chamber and the top of the piston can form carbon deposits and cause abnormal combustion of the integrated vehicle engine; There is gum on the piston ring and valve stem, which will cause these parts to bite and stick, and aggravate the wear of various components of the all-in-one vehicle engine.

機油變質(zhì)的原因主要有以下幾點(diǎn):

The main reasons for oil deterioration are as follows:

①機件摩擦所產(chǎn)生的屑末沉積;

① Chip deposition generated by friction of parts;

②燃燒時(shí)，高溫氧化產(chǎn)生的漆膜、沉積物膠質(zhì)和積碳;

② Paint film, deposit colloid and carbon deposit produced by high-temperature oxidation during combustion;

④燃燒時(shí)生成的酸性物質(zhì);

④ Acids generated during combustion;

⑤曲軸箱通風(fēng)裝置阻塞，機油散熱不良，機油受熱自然形成膠質(zhì);

⑤ The crankcase ventilation device is blocked, the engine oil has poor heat dissipation, and the engine oil naturally forms colloid when heated;

⑥過(guò)濃混合氣中未霧化的汽油混人機油;及水套中的冷卻水滲人機油等。

⑥ The un atomized gasoline in the rich mixture is mixed with the engine oil; And the cooling water in the water jacket seeps into the engine oil, etc.

機油在一體車(chē)發(fā)動(dòng)機里怎么會(huì )變質(zhì)？以上就是小編給你整理的原因，您可以作為參考了解起來(lái)，更多相關(guān)內容就來(lái)我們網(wǎng)站http://m.jackpetty.net咨詢(xún)吧！
