How should excavator handle impotence2019-05-31

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:
