Also strange excavator track wear fast! Here are five things you should pay attention to: As excavators are usually constructed in a harsh environment, it is inevitable that the track will be loosened, damaged or broken. Do you have any understanding of the causes of track damage?

Use and maintenance of "four wheel and one belt": Take the excavator as an example, the maintenance cost of "four-wheel and one-belt" accounts for about 60% of the annual maintenance cost of the excavator, so it is necessary for us to know how to properly use and maintain "four-wheel and one-belt".

Does the dredge often break its chain? Use these tips to help you avoid them easily!: Underground excavators often lose their chains in their work, that is, their crawlers fall off. Especially for older machines, chain dropping is a common occurrence. In this case, experienced old drivers will take a very short time to re-install, which will not affect the efficiency of the work, but for some novices, this can become a major problem.

How should excavator handle impotence: The whole machine is weak in several aspects, one is when the external load is large engine speed reduction, which is manifested in the following two aspects:

Why is the working speed of excavator slower: If it is used for many years of excavator, the speed gradually slow, this belongs to normal wear and tear. Main factors which the machine parts wear cause the loss of engine power and drainage for hydraulic system, thus a series of failures are shown, internal energy consumption due to leakage, produce large amounts of heat energy, rapid heating up, the whole system of the hydraulic oil and engine oil viscosity decreased, the whole system to produce high temperature, characterized by cool car faster more heat more slowly, which requires all machine overhaul, to repair worn transfinite parts replacement. If it is a new excavator suddenly slow, this will be first simple after complex, check from the following aspects: first check whether the circuit fuse is broken or short circuit; Whether the pilot pressure is normal; Servo control valve - whether the servo piston is stuck; Distributor confluence failure, etc. Ruled out other possibilities, and finally dismantled the hydraulic pump.

How does the excavator engine speed drop: First to test the engine output power itself, if the output power is much lower than the rated power engine, so at the construction site should start from the simplest method, first to see if the fuel filter blockage, whether there is a leak in the fuel oil road, the plunger fuel pump, fuel injection, delivery valve whether serious wear and tear, air filter inlet is obstructed, engine turbocharger, the turbocharger is damaged, the engine is fast heat, oil viscosity decreased, cause the loss of cylinder wall closed lax compression ratio, it causes serious mixes up in cylinder liner wear components, such as engine valve closes lax, These are the factors that seriously affect the engine power. If excluding the engine itself output power shortage, it will consider the hydraulic pump flow and engine output power matching problem.

Type of steel crawler plate: Belt plate is one of the chassis parts of construction machinery. It is a kind of wearing part of the used construction machinery. At present, crawler board materials mainly include rubber, high manganese steel, medium manganese steel, low alloy steel, ductile iron, aluminum alloy and aluminum matrix composite materials. Among them, steel crawler board is the most widely studied and applied, which is mainly divided into the following three categories:

Do you all know what parts an excavator has: Actually now excavator parts of a wide variety of workability, already can achieve more than a machine N of usage

The world's largest excavator, costing 560 million yuan, can empty a mountain in a day: When we see an excavator, we all feel that it is very big and dangerous. But we still have one of the biggest excavators in the world, which is equivalent to several of our common excavators.

The method to solve the problem of the excavator's black smoke and unrefrigerated air condition: Excavators in use process will appear a lot of problems, such as excavator smoke suddenly, or the excavator high temperature air conditioning not refrigeration, these questions are need to troubleshoot and solve one by one, must not be dragged with the problem, this also is likely to lead to more and more serious problem, but for excavator maintenance, must be particular case is particular analysis, suit the remedy to the case when maintenance.

What should the excavator pay attention to when operating under special working conditions?: In all kinds of construction projects, it is inevitable to encounter all kinds of complex working conditions, which is also determined by the diversity of engineering construction conditions.

Fault analysis of excavator with high water temperature and oil temperature: In excavator construction, it is very common that water temperature and oil temperature are too high.
