康明斯發(fā)動機N/K全系列發(fā)動機不好啟動的原因與排除?

日興動力建議按以下方法處理

Nikko power suggestion processing according to the following method

一、油箱沒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。

A tank, no oil or fuel oil low result can not be normal oil supply caused, fill up the tank with oil on it.

二、噴油器出現(xiàn)問題，

Problem two, injector,

(1) 噴油器O型密封圈損壞或丟失，檢查密封圈；

(1) the fuel injectors O type sealing ring is damaged or lost, check the sealing ring;

(2) 噴油器有污物或者調(diào)節(jié)不當(dāng)，對噴油器重新調(diào)整，檢查清洗濾網(wǎng)或者更換。

(2) the injector with dirt or improperly adjusted, re adjustment of the fuel injector, check the cleaning filter or replacement.

三、進(jìn)氣系統(tǒng)問題

Three, the intake system

(1)進(jìn)氣管堵塞，檢查空氣濾清器和進(jìn)氣管路；

(1) the intake pipe is blocked, check the air filter and the intake pipe;

(2)進(jìn)氣系統(tǒng)阻力超出技術(shù)規(guī)范 嚴(yán)格參照規(guī)范來執(zhí)行修改。

(2) the intake system resistance beyond the technical specification strictly according to regulations to implement change.

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。

There are four blocked the intake pipe, fuel oil, check on the air cleaner and the air inlet pipe, debris removal.

五、燃油泵出現(xiàn)問題

Five, the fuel pump problem

(1)燃油輸油泵進(jìn)口濾網(wǎng)堵塞 解決辦法就是清除污物；

(1) the fuel pump inlet filter blockage solution is to remove the dirt;

(2)齒輪泵驅(qū)動軸斷裂或者錯位，重新調(diào)整或者更換新的康明斯驅(qū)動軸配件。

(2) gear pump driving shaft fracture or dislocation, re adjust or replace the new Cummins drive shaft parts.

六、燃油進(jìn)油口問題

Six, the fuel oil inlet problem

(1)進(jìn)油口因雜物賭塞，仔細(xì)檢查濾清器是否存在異物，及時清理；

(1) the inlet due to debris jam, carefully check whether there is foreign body cleaning filter;

(2)進(jìn)油口漏氣，仔細(xì)檢查接頭和軟管是否接緊。

(2) the inlet air leakage, carefully check the fittings and hose is connected tightly.

七、燃油質(zhì)量問題

Seven, fuel quality

(1)燃油等級與應(yīng)用類型不符；

(1) the fuel level and application type does not match;

(2)劣質(zhì)燃油或者燃油中混有水。及時更換合乎等級的正規(guī)燃油。

(2) the inferior fuel oil or fuel oil mixed with water. Replace the normal fuel a level in time.

八、燃油電磁閥出現(xiàn)問題 一般燃油電磁閥因線路接觸不良或者斷線， 試著手動控制開關(guān)啟動看看，同時檢查線路是否出現(xiàn)問題。康明斯N/K系列柴油發(fā)動機相對來說相較Q系列電噴機來說簡單多了，最主要的就是如何通過這個異常啟動來發(fā)現(xiàn)發(fā)動機是否出現(xiàn)問題，如何在日常運行、維修的過程中去通過以上原因參照解決啟動問題，是維持發(fā)動機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)動機機油消耗大或發(fā)動機大修后燒機油？

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

一、康明斯發(fā)動機為什么會消耗機油？

Why, Cummings engine oil consumption?

為了降低發(fā)動機各運動部件的磨耗,減少機械的摩擦阻力,延長機器的壽命,具有相對運動的零件之間必須施加潤滑。消耗機油的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)動機體外

The 2: engine through in vitro

二：康明斯缸套、活塞是機油消耗的主要部位

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

1:缸體表面加工出的儲存潤滑油的花紋隨著機器的磨和,花紋的尖角在逐步磨平,因此機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：康明斯活塞上行時機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)管也是一對熱負(fù)荷較大的運動副,潤滑的方式是發(fā)動機機油飛濺潤滑,潤滑后的機油也流到燃燒室內(nèi)燃燒致使損耗,但是該機油的有效消耗能夠有效的延長氣門和氣門導(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和關(guān)機時消耗部分機油

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滑油的,因此,在啟動和關(guān)閉機器時,總是要有少量的發(fā)動機機油漏出,這也是所有采用廢氣渦輪增壓器所具有的特點.

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)動機下排氣也排出部分機油

Six: Cummings diesel engine exhaust and exhaust part oil

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

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)動機添加機油周期不一樣？

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

康明斯發(fā)動機油底殼的容積不同，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)動機大修后燒機油？

Eight: Cummings engine overhaul burning oil?

康明斯柴油發(fā)動機油的正常消耗量為每消耗100噸柴油，消耗機油2.5kg。若超標(biāo)，則視為燒機油故障。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加用了汽油機機油(包括美國的美孚汽油機機油);

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)動機大修后在磨合期內(nèi)可能是有點耗機油

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

6發(fā)動機在大修時選擇配件不當(dāng)

The 6 engine in the overhaul of improper selection of accessories

7發(fā)動機大修時安裝問題

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機油量是否正常

9 whether the correct volume of oil

10機油安全閥是否有松了

10 oil safety valve if there are loose

11機油中是否混有水或燃油

11 oil is mixed with water or oil
