Supply Longnan Sumitomo crawler hydraulic excavator Repairer This article provides shared by fly excavator plant maintenance, if you do not know where about excavator please feel free to call the fly excavator plant maintenance repair Tel: [139] ------ [9639] ------ [3931] fly excavator maintenance plant in Chongqing, was established since 2003, there have been over 1000 cases of excavator maintenance success stories, after eight years of development and growth, fly excavator plant maintenance already have team of more than 50 service engineers excavator maintenance team, including engine maintenance engineer 5; hydraulic system engineer 5; circuitry senior four. I plant imported "Hydraulic Pump debugging, hydraulic valve comprehensive test, the computer board debugging Taiwan"; and other professional excavator maintenance inspection and testing equipment, all designed to provide a more accurate test data, faster service, more sophisticated technical support Longnan Sumitomo excavator Repairer sharing "Sumitomo excavator SH350-5 idling unstable fault repair case" Sumitomo excavator SH350-5 idling unstable fault analysis, fault maintenance program to view: 1 2 due to increase idle speed. repair and adjust governor, 3 overhaul repair the fuel pump to adjust the idle spring 4: 5 adjustment and maintenance of the nozzle so that the fuel injection quantity is consistent 6 7 fuel filling qualified adjust injection timing, a good tune 8 and tighten the connector to the engine idle speed instability itself Sumitomo excavator SH350-5 reasons: 1. adjust the idle speed is too low 2 governor failure, each axle pin wear, the gap is too large hinge point block... rack movement hairpins 3 idle spring vein shrinkage is too small. idling spring break. 4 fuel pump failure, fuel injection quantity and injection pressure fluctuations. 5 injector fault, issuing the nozzle needle, the valve seal instability 6 grade fuel does. fuel contains water. 7 oil timing angle changes. 8 motive itself is faulty. >>>>>>>>>>>>>>>>> Longnan Sumitomo excavator plant maintenance << <<<<<<<<<<<<<<<<<< Longnan Sumitomo excavator Repairer sharing "; Sumitomo excavator Latest News"; a revolutionary force and the driving force mining, may be implemented in any operating environment a large amount of work. Sumitomo's new hydraulic system "; SIH: S"; and a new engine system "; 5"; further improve the operating speed and environmental performance. Heart and good operability of the control valve through a hydraulic circuit optimization and feel of the operating state of the signal, smooth operator convey the subtle changes in force, to achieve a higher operability. The upper part of the body's ability to improve balance + travel (composite operability) As the traveling speed of the upper body with the manipulation of inputs change, even in the hills or high places that require complex operations, it is possible to smoothly carry out the job. Unprecedented amount of work, the knob integrated model with the new P mode to achieve an unprecedented amount of work. Switch the mode dial linkage, no complicated button operations. P mode operation volume increase of 7% based on job status, automatically increase mining capacity during heavy excavation, according to the job status quickly without key operation automatically increase mining capacity.
