You'd better check if the grader gear lever is in place. Some are directly driven by the lever and most are cable type. The lever has good power transmission, but installation is limited, and the opposite is true for. If the joystick can be in place without changing speed, then you should consider the variable speed pump. First check if the pressure gauge indicator in the cabin is at the normal value, 80. % of this concerns the pump, but also the motor. Check the oil filter, if clogged, as well as the torque converter variable speed valve. Since most motor graders now use hydraulic torque converters, consider the pressure value. of the variable speed valve and whether it is clogged, as well as the inside of the variable speed valve. There is a spring, and if the spring is broken, it will also cause instability ofpressure. If the transmission valve is okay, there will be some. there are only internal problems with the hydraulic coupling and torque converter! ! These are the general troubleshooting methods you mentioned. I have little talent and knowledge, so it's hard to say if I can help you Haha,
The fuel consumption of the excavator is estimated at 26.904 kg per person. hour.
This type of excavator is a medium-sized excavator of 21 tons. The useful mass of the entire machine is 20,850 kg. The rated power of the engine is 118 kW, the rated speed (rpm) is 2000, and the engine displacement is 4.9 L. The fuel consumption rate is ≤228 (g) per kilowatt hour . When operating at rated power, the fuel consumption per hour is: 118 times 228 equals 26,904 (g), which is converted to 26.904. kg.
