Supply maintenance Anshun Carter 308 excavator digging machine maintenance weakness, unified national service hotline: [139] - [9639] - [3931] Carter excavator plant maintenance _ Carter 320CX240B excavator inability article by the maintenance of the master feed excavator Caterpillar excavator. inability phenomenon can be divided into two cases: the first one is the engine does not hold the car, feeling very light load; the second is when the boom or arm extended in the end, the engine seriously hold the car, or even turn off Anshun Carter 308 excavator. weakness failure analysis and solutions: First: That weakness but the engine does not hold mining car digging force depends on the size of a main pump output pressure, and whether the engine hold the car is absorbed by the oil pump and the engine torque between the output torque .2 determine the relationship does not hold the car engine, which shows a small pump absorption torque, the engine load is light 3 If relief pressure value below the specified value, it indicates that the overload relief valve setting of the institution of the hydraulic circuit is incorrect , then you need to turn the adjusting screw to adjust the machine a second: That mining weakness, while the engine 1 and the engine does not hold the car hold car compared to the machine, the engine hold the car indicates that the pump absorption torque is greater than the engine output torque. so that the engine overload .3 After careful after viewing for troubleshooting problems, so the engine speed sensing system will return to normal function, and hold car phenomenon will disappear over the fly.
