Take Kato 512 excavator as an example to explain in detail the reasons for the slow engine speed of excavator and the machine holding, as well as what to do. The engine speed of Kato hd512 excavator is slow and the machine holding analysis:
1. If the engine speed is slow, check that the engine speed sensor is on the flywheel housing. The measured voltage should be AC1 5-2.5v
It can't be adjusted directly through the computer, but when you replace the throttle lever, you can use the computer to reset it. The specific method is too difficult, and the brand and method are different.
2. There are many reasons for holding the excavator, such as engine, hydraulic pressure and electrical The easiest way is to see if there is black smoke when holding the car. If so, it indicates that there are more reasons for the engine, such as air filter, fuel problem, turbocharger, etc If there is no black smoke, but there is alarm or fault code display at the same time, it indicates that there are more electrical reasons, mainly caused by TVC valve and pc-epc solenoid valve. In addition, there are hydraulic reasons, mainly because of the output power of hydraulic pump and the output power of Daewoo engine. The fault points are about PC valve, CO valve, NC valve, LS valve, jet sensor, servo piston, etc.
