In the maintenance of excavators, a very common problem is the engine speed out of control failure, commonly known as "flying car" phenomenon. In the maintenance of excavators at present, the situation of speed out of control is getting higher and higher, it will cause major accidents such as cylinder-pestle and broken axle in diesel engines. Diesel engines usually only appear runaway failure when they are just starting up or when the load suddenly disappears or lightens, and in the load below the work is not a runaway failure, let's take a look at the excavator dimension
On the mechanical side, we all know that whether new or used, there will be many problems, such as repair of excavators. In the face of the general trend of excavators, the demand of the excavator repair industry is also growing, below we come to analyze the problem that the excavator is unable to work slowly.
For this kind of problem, it is usually especially common in summer, but in some cases, in winter, some cases, there are also cases. However, do not ignore this kind of problem. If this kind of problem occurs, then the excavator is out of order. Well, this kind of problem, how Do You Fix It?
Must have had the construction machinery work experience person more or less has had the diesel engine start the breakdown question, then, after all what reason causes this phenomenon to occur frequently? Is there a solution? Following the footsteps of Xiamen Jinhaihua Construction Machinery Co. , Ltd. to analyze the secrets of the diesel engine one by one.
What can we do to reduce the faults of the machine and extend the service life of the pick-up machine?
Fuel Management: According to the ambient temperature, choose different grades, qualified fuel. Otherwise, poor quality fuel with high sulfur content will cause damage to the engine; diesel fuel can not be mixed with impurities, lime soil and water, or it will cause premature wear and tear of the fuel pump; the pickup driver is required to fill up the fuel tank after daily operation, avoid dripping on the inner wall of fuel tank; open the Drain Valve at the bottom of fuel tank before daily operation.
Steel grab is a kind of special engineering machinery which is widely used in steel works, smelters, ports, wharves and scrap transfer industries, equipped with different grab (such as plum flower grab, Shell grab, round wood grab, billet grab, hydraulic scissors, hydraulic pliers, etc.) to meet different conditions of different customers on scrap steel, ore, coal, bulk fertilizer, sand loading and unloading needs.
