When is life, with a strong, it will slowly reduce the throttle, and then turn off. The engine doesn't smoke. Small arms and walking are the most serious. Other actions are better and the engine loses speed. Sometimes it's normal to do what you do. Adjust the safety valve pressure, cleaning the distributor, there is no effect (the engine's large pump, oil circuit is no problem)There is no problem with the engine
1., although you said that the inspection is no problem, but still suggested from the most basic fuel road cleaning, replace all filter elements, began to check. The diesel pump is removed from the oil line to see if the injection length can reach about 6~7cm.2. small arm and walk, mainly pump 2 oil supply, check the main pump cleaning 2 of the regulator.3. choke 90% is fuel road failure, it is best to carefully check the oil circuit to confirm that there is no leakage of space, such as pipe joint seal damage, filter is not in place, oil-water separator, water supply cover is not tightened, etc.. Direct connection with fuel tank test can be used.
You still have to find a repair do not know where you are like you a wrong diagnosis is not only a waste of money but also a waste of time and effort in Hangzhou, Xiaoshan has a very good mechanic tall fat with a fairly good technical Landwind we are all the way to repair the ten time he invited ten times to help you out with no recurrence but I don't know if he contact number I see the information you send me or hydraulic pressure instability or lock problem are you sure no problem you cleaned oil oil oil have a plurality of small screen and the mailbox surface is cleaned? Has the atomizer been tested yet? Good luck. No, you go to Xiaoshan. If there's any need, I can ask you about that. Good luck
[cause of trouble]1 hydraulic large pump failure2 excavator two valve problems3 hydraulic pump regulator variable chaos will also choke machine flameout failureFourIs the confluence valve of the solenoid valve blocked?5 hydraulic oil will also be more excavators hold machine flameout failureSixIf the fuel supply is poor, check whether the oil pipe is blocked or leaking[corresponding cause of failure]1 there is a problem with the circuitTwoCheck the wood and see if it's blocked. If you don't see it, get into the system3 there's something wrong with the engine4 there is water in the fuel lineFiveIf the air enters the fuel pipe, the excavator will stop and stall6, the gas supply is poor, causing the engine to stall7, the power of the engine is insufficient to achieve the power required by the hydraulic pumpEightThe hydraulic part has the stem to clamp, also can the excavator hold down the engine to extinguish the faultNineValve stem movement is not smooth, resulting in hydraulic power is greater than the output power of the engine, so the engine will stall[supplement]Corresponding troubleshooting:1., although you said that the inspection is no problem, but still suggested from the most basic fuel road cleaning, replace all filter elements, began to check.
