日興動(dòng)力建議按以下方法處理

Nikko power suggestion processing according to the following method

一、油箱沒(méi)油或者燃油油位低導(dǎo)致不能正常供油引起的，給油箱加滿油就可以了。

四、燃油油道中存在雜物堵塞進(jìn)氣管，著重檢查空氣濾清器和進(jìn)氣管路，清除雜物。

八、燃油電磁閥出現(xiàn)問(wèn)題 一般燃油電磁閥因線路接觸不良或者斷線， 試著手動(dòng)控制開(kāi)關(guān)啟動(dòng)看看，同時(shí)檢查線路是否出現(xiàn)問(wèn)題?？得魉筃/K系列柴油發(fā)動(dòng)機(jī)相對(duì)來(lái)說(shuō)相較Q系列電噴機(jī)來(lái)說(shuō)簡(jiǎn)單多了，最主要的就是如何通過(guò)這個(gè)異常啟動(dòng)來(lái)發(fā)現(xiàn)發(fā)動(dòng)機(jī)是否出現(xiàn)問(wèn)題，如何在日常運(yùn)行、維修的過(guò)程中去通過(guò)以上原因參照解決啟動(dòng)問(wèn)題，是維持發(fā)動(dòng)機(jī)正常使用壽命的必要選擇。

Eight, fuel solenoid valve problems generally fuel solenoid valve because of poor contact or line break, try to have a look at the manual control switch, check wiring problems. Cummins N/K series diesel engine is compared with Q series injection machine is simple, the most important is how to discover whether the engine problems through the abnormal start, how to go through the above reasons refer to solve problems in the process of starting daily operation, repair, is a necessary choice to maintain normal engine service life.

康明斯柴油發(fā)動(dòng)機(jī)機(jī)油消耗大或發(fā)動(dòng)機(jī)大修后燒機(jī)油？

Large or overhaul of engine oil consumption for Cummins diesel engine burning oil?

一、康明斯發(fā)動(dòng)機(jī)為什么會(huì)消耗機(jī)油？

Why, Cummings engine oil consumption?

為了降低發(fā)動(dòng)機(jī)各運(yùn)動(dòng)部件的磨耗,減少機(jī)械的摩擦阻力,延長(zhǎng)機(jī)器的壽命,具有相對(duì)運(yùn)動(dòng)的零件之間必須施加潤(rùn)滑。消耗機(jī)油的2種方式：

In order to reduce the moving parts of the engine wear, reducing friction machine, prolong the service life of the machine, with the relative motion between the parts must be applied lubrication. 2 ways of consumption of oil:

1:燃燒室內(nèi)消耗

1: combustion chamber consumption

2:排出發(fā)動(dòng)機(jī)體外

The 2: engine through in vitro

二：康明斯缸套、活塞是機(jī)油消耗的主要部位

Two: Cummings is the main part of cylinder liner, piston oil consumption

1:缸體表面加工出的儲(chǔ)存潤(rùn)滑油的花紋隨著機(jī)器的磨和,花紋的尖角在逐步磨平,因此機(jī)油的消耗也在逐漸減少

The 1: store oil cylinder machined surface pattern with machine and grinding, pattern angle gradually removed, therefore the oil consumption is also reduced gradually

三：康明斯活塞上行時(shí)機(jī)油被泵入燃燒室燃燒后,被消耗

Three: Cummings when piston upward oil is pumped into the combustion chamber, is consumed

四：康明斯氣門和氣門導(dǎo)管之間也有機(jī)油消耗

Four: there are oil consumption between the Cummings valve and valve guide

氣門和氣門導(dǎo)管也是一對(duì)熱負(fù)荷較大的運(yùn)動(dòng)副,潤(rùn)滑的方式是發(fā)動(dòng)機(jī)機(jī)油飛濺潤(rùn)滑,潤(rùn)滑后的機(jī)油也流到燃燒室內(nèi)燃燒致使損耗,但是該機(jī)油的有效消耗能夠有效的延長(zhǎng)氣門和氣門導(dǎo)管的壽命

Motion of the valve and valve guide is a pair of large heat load, lubrication is engine oil splash lubrication, the lubrication oil flow to the burn after the loss of the combustion chamber, but effective consumption of the engine oil can effectively prolong the lifetime of valve and valve guide

五：康明斯渦輪增壓器啟動(dòng)和關(guān)機(jī)時(shí)消耗部分機(jī)油

Five: Turbocharger startup and shutdown time consumption part of oil

由于廢氣渦輪增壓器是依靠進(jìn)排氣的平衡壓力密封潤(rùn)滑油的,因此,在啟動(dòng)和關(guān)閉機(jī)器時(shí),總是要有少量的發(fā)動(dòng)機(jī)機(jī)油漏出,這也是所有采用廢氣渦輪增壓器所具有的特點(diǎn).

Because the turbocharger is dependent on the balance pressure inlet and exhaust sealing lubricating oil, therefore, in the start up and shut down the machine, always have a small amount of engine oil leakage, which is all the exhaust turbocharger features

六：康明斯柴油發(fā)動(dòng)機(jī)下排氣也排出部分機(jī)油

Six: Cummings diesel engine exhaust and exhaust part oil

為了使康明斯發(fā)動(dòng)機(jī)能夠連續(xù)的輸出功率,曲軸箱必須和大氣相同,因此必須有一個(gè)管道來(lái)連接曲軸箱和大氣,俗稱”下排氣管”,通過(guò)活塞環(huán)泄露的少量高溫燃?xì)馔ㄟ^(guò)”下排氣管”導(dǎo)入大氣當(dāng)中,同時(shí)將由于曲軸高速旋轉(zhuǎn)時(shí)激起的機(jī)油油霧排到大氣當(dāng)中,致使有少量的機(jī)油消耗.

In order to make the Cummings engine is capable of continuous output power, the crankshaft box must be the same and the atmosphere, so there must be a pipeline to connect the crankcase and the atmosphere, commonly known as the "tube", a small amount of high temperature exhaust gas through the piston rings leak through the "exhaust pipe" into the atmosphere when, at the same time, because the oil mist stirred crankshaft when the rotary speed of the discharge into the atmosphere, causing a small amount of oil consumption

七：為什么不同發(fā)動(dòng)機(jī)添加機(jī)油周期不一樣？

Seven: why different engine add oil cycle is not the same?

康明斯發(fā)動(dòng)機(jī)油底殼的容積不同，油底殼形狀不一樣，油標(biāo)尺設(shè)定刻度不一樣。所以添加的頻次也不一樣，但正常情況下每千升柴油所消耗的機(jī)油量比例差別不大。

The volume of the Cummings engine oil pan, oil bottom shell shape is different, the oil scale set the scale is not the same. So adding frequency is not the same, but little difference in oil consumption per kiloliter diesel ratio under normal conditions.

八：康明斯發(fā)動(dòng)機(jī)大修后燒機(jī)油？

Eight: Cummings engine overhaul burning oil?

康明斯柴油發(fā)動(dòng)機(jī)油的正常消耗量為每消耗100噸柴油，消耗機(jī)油2.5kg。若超標(biāo)，則視為燒機(jī)油故障。其原因有:

Normal consumption of Cummins diesel engine oil quantity for each consumed 100 tons of diesel oil, oil consumption for 2.5kg. If exceed the standard, is regarded as a burning oil fault. The reasons are:

1加用了汽油機(jī)機(jī)油(包括美國(guó)的美孚汽油機(jī)機(jī)油);

1 with the gasoline engine oil (including oil Mobil gasoline engine of American);

2汽缸密封不良(如活塞環(huán)失效，拉缸等);

2 cylinder seals bad (such as failure of piston ring cylinder, etc.);

3增壓器兩端密封損壞;

3 supercharger ends seal damage;

4進(jìn)氣門擋油罩掉出或損壞。

4 inlet valve oil blocking cover out of or damage.

5發(fā)動(dòng)機(jī)大修后在磨合期內(nèi)可能是有點(diǎn)耗機(jī)油

The 5 engine overhaul in the running in period may be a little oil consumption

6發(fā)動(dòng)機(jī)在大修時(shí)選擇配件不當(dāng)

The 6 engine in the overhaul of improper selection of accessories

7發(fā)動(dòng)機(jī)大修時(shí)安裝問(wèn)題

Installation of the 7 engine overhaul

8檢查油壓表是否正常

8 check the oil pressure gauge is normal

9機(jī)油量是否正常

9 whether the correct volume of oil

10機(jī)油安全閥是否有松了

10 oil safety valve if there are loose

11機(jī)油中是否混有水或燃油

11 oil is mixed with water or oil
