康明斯柴油發(fā)動機的柴油滲透到油底殼里的故障維修與排除

柴油滲入到油底殼，這是非常有害的，它不僅降低油的粘度和機油壓力，但也稀油中的各種添加劑內(nèi)容。如果滲透能力，它甚至?xí)?dǎo)致軸承倦擔(dān)在這里，我們介紹一些故障排除，例如康明斯發(fā)動機NT-855型。

　　1. 康明斯柴油發(fā)動機PT燃油泵

　　康明斯PT燃油泵有一個雙磁和手動切斷閥，點火開關(guān)打開時，磁性關(guān)閉閥門打開，油路連接點火開關(guān)處于關(guān)閉狀態(tài)時，關(guān)閉閥門密封油路是關(guān)閉的。關(guān)閉閥門密封失敗時，燃料會自動流進(jìn)注射器通過關(guān)閉閥門，并滲透到油底殼通過燃燒室。此時，應(yīng)拆除和更換密封件切斷閥。

　　2?？得魉共裼桶l(fā)動機噴油器

　　噴油器的作用，是衡量燃料進(jìn)入燃燒室，然后按。當(dāng)過大或損傷，噴油嘴進(jìn)入燃燒室的燃料將下降和停止?fàn)顟B(tài)下滲入到油底殼。此時，我們需要拆除和更換不正常的噴油器。如果失敗，向上和向下的O形圈燃料將下降到閥室和通過密封燃燒室，進(jìn)入油底殼。當(dāng)時，應(yīng)拆除和更換。

　　3?？得魉共裼桶l(fā)動機油箱

　　位于較高的位置PT燃油系統(tǒng)的油箱，必須有一個手動閥安裝在油箱出口，以防止燃料通過浮子油箱和PT泵到噴油器，康明斯發(fā)動機關(guān)閉，閥門出現(xiàn)故障時，通過燃燒室的燃料會滲入油底殼。在這一點上，閥門應(yīng)修理或更換。 

　　4?？得魉共裼桶l(fā)動機浮罐

　　必須有浮球閥和錐形閥安裝在浮坦克將保持燃油水平，使燃料穩(wěn)步。當(dāng)浮球閥或錐閥處于關(guān)閉狀態(tài)失敗。通過浮箱，油箱將進(jìn)入油底殼。在這一點上，浮閥或錐形閥應(yīng)修理或更換。

Diesel Cummings diesel engine oil bottom shell penetrated into the fault exclusion

Diesel oil into the oil pan, which is very harmful, it not only reduce the viscosity and oil pressure oil, but also dilute various additives content in oil. If the infiltration capacity, it may even lead to bearing weariness. Here, we introduce some troubleshooting, such as the Cummings engine NT-855.

1 Cummings PT diesel engine fuel pump

Cummings PT fuel pump with a double magnetic and manual shut-off valve, when the ignition is switched on, the magnetic valve open, circuit connected with the ignition switched off, close the valve seal oil is closed. Close the valve seal failure, the fuel will automatically flow into the syringe by closing the valve, and penetrate into the oil sump through the combustion chamber. At this time, should be removed and replaced the seal off valve.

2. Cummings diesel engine fuel injector

Fuel injector, is a measure of fuel into the combustion chamber, and then press the. When is too large or damage, fuel injector into the combustion chamber of the fuel will drop and stop state into the oil pan. At this time, we need to remove and replace the fuel injector is not normal. If it fails, to the O ring fuel up and down will drop to the valve chamber and the combustion chamber is sealed, into the oil pan. At that time, should be removed and replaced.

3. Cummings diesel engine oil tank

Location of the PT fuel system in higher fuel tank, there must be a manual valve is installed in the tank outlet, in order to prevent the fuel tank and PT float through the pump to the fuel injectors, Cummins engine off, the valve failure, through the fuel combustion chamber will seep into the oil pan. At this point, the valve should be repaired or replaced.

4. Cummings diesel engine floating tank

There must be a floating ball valve and cone valve installation will maintain the fuel level in the float tank, fuel steadily. When the floating ball valve or cone valve in the closed state failure. Through the floating box, into the oil sump tank. At this point, the float valve or conical valve shall repair or replace.

Cummings PT fuel system return oil manifold equipped with a one-way valve, keep the fuel injector inlet pressure is stable, and the floating box injection, in order to prevent fuel. The check valve failure, which flows through the oil return manifold and fuel injector into the oil pan. At this point, the one-way valve should be carried out to repair and replacement.

　　康明斯PT燃油系統(tǒng)的回油歧管配有一個單向閥，保持噴油器進(jìn)油壓力穩(wěn)定，并通過浮箱噴油，以防止燃油。單向止回閥失敗時，燃料將流過回油歧管和進(jìn)樣器進(jìn)入油底殼。在這一點上，單向閥應(yīng)進(jìn)行維修和更換。
