Yesterday, Master Liu called the excavator and said anxiously: "Our Kato excavator has always performed well! Let our construction progress go smoothly, but today the action suddenly slowed down and even went on strike! We aimed at the engine speed of this excavator Slow problem to analyze.
Kato HD512 excavator engine speed is slow
Stop machine analysis:
1. The engine speed is slow. Check the engine speed sensor on the flywheel housing. The measurement voltage should be between AC1.5-2.5V.
Can not be adjusted directly through the computer, but when you replace the throttle lever, you can use the computer to reset, the specific method is too difficult, and the brand is different, the method is also different.
2. There are many reasons for the excavator to hold the machine, such as engine, hydraulic and electrical aspects may cause the failure of holding the car. The easiest way is to see if there is black smoke while holding the car. If so, explain the engine The reasons are larger, such as: air filtration, fuel problems, turbochargers, etc.
If there is no black smoke, but there is an alarm or fault code display at the same time, it means that the electrical reasons are larger, mainly caused by TVC valves and PC-EPC solenoid valves, and the hydraulic reasons, mainly because Pump output power Daewoo engine output power, the fault point is about PC valve, CO valve, NC valve, LS valve, jet sensor, servo piston and so on.
