Excavator Pump Slow

When the excavator is working on the construction site, it often gives people a feeling of stability and efficiency, but if the components of the hydraulic system are damaged to a certain extent, the speed of the excavator will slow down, which requires maintenance personnel to troubleshoot. The deceleration of the excavator machine will also vary. The following two situations are the more common faults that Elephant Fluid Power has summarized through years of business experience.

Engine speed drops. First, test the output power of the engine itself. If the output power of the engine is lower than the rated power, the cause of the failure may be poor fuel quality, low fuel pressure, incorrect valve clearance, a certain cylinder of the engine not working, fuel injection timing, incorrect fuel quantity, incorrect setting, and leakage of the intake system. Air, brakes and their lever failure, turbocharger carbon deposits. If the pump control system fails, the optimal load matching state of the engine, pump and valve under different working conditions will not be achieved, and the excavator will not work normally. Such faults should start with the electrical system, and then check the hydraulic system. Finally check the mechanical transmission system.

Work has slowed down. The main reason for the slow working speed of the excavator is that the wear of various parts of the whole machine leads to the decrease of engine power and the internal leakage of the hydraulic system. The hydraulic pump of the excavator is a piston variable pump. After working for a period of time, the hydraulic components in the pump (cylinder block, plunger, distribution plate, nine-hole plate, turtle back, etc.) will inevitably wear out excessively, resulting in internal leakage. The data of various parameters are not coordinated, resulting in insufficient flow, high oil temperature and slow working speed. At this time, the whole machine needs to be overhauled, and the worn parts are repaired and replaced.

After these two cases, some parts need to be replaced. It is recommended that you choose the products of Elephant Fluid Power Co., Ltd. for replacement, because we are professional in this area, and our products are based on the original designs of major brands. Can produce nearly identical products to many big name hydraulic products. All of the replacement items mentioned above are available for sale, and they are very high-end quality and affordable.
