The excavator is very large, and any situation will have a certain impact. Next, I will tell you how to troubleshoot the excavator when it breaks down. Jinan excavator renters will first talk about the conditions for good starting performance of the excavator.
⑴ Sufficient starting speed is required. High starting speed, less gas leakage in the cylinder, short time for compressed air to transfer heat to the cylinder wall, less heat loss, so that the gas temperature and pressure at the end of compression can be increased. It is generally required to rotate at 1_ 0_ 0_ r_/_ m_ i_ n_ above.
(2) The air cylinder shall have good sealing performance. This can further reduce the gas leakage, ensure that the gas has sufficient combustion temperature and pressure at the end of compression, and the compression pressure of the cylinder shall not be lower than 8% of the standard value_ 0_%_。
⑶ It is required that the fit clearance between the engine and the running parts is appropriate and the lubrication is good.
(4) The battery shall have sufficient starting capacitance and the technical condition of the starting circuit shall be normal.
(5) The starting fuel quantity shall meet the requirements, the injection quality shall be good, and the injection advance angle shall meet the requirements.
(6) Use qualified fuel.
Note that the price of a repair is very expensive, not everyone can afford it. First of all, once you find that your excavator engine suddenly stalls, you should immediately find a way to change it. Stalling is very common, and it may lead to more serious failures if you act rashly.
The first thing to consider after flameout is the fuel tank. Check whether there is oil leakage or not it is too clean. These two reasons may also lead to the sudden flameout of the excavator.
Carefully check whether there is no oil in the mailbox. If there is any, you must purchase according to the model. At the same time, check the pressure and water temperature of the oil, and whether other instruments are operating normally to determine whether there is a good cooperation between the parts.
Through these methods mentioned above, you can find out the cause of the failure. If you have any problems, please come to our website http://www.ycgjglcl.com Consult!
