Carter Excavator Repair
Characteristics of Carter Excavator Engine Speeding
The knocking sound changes from small to large, and finally the connecting rod bolts completely fall off or break, and the connecting rod and the bearing cover are thrown out. Handling measures (pointing to the solution to the problem): immediately stop overhaul, replace New parts excavator repair refers to the technical activities performed to restore the function of the equipment after its technical condition deteriorates or fails, including various planned repairs and unplanned fault repairs and repairs. Excavators perform regular vehicle cleaning of the excavator. The main purpose of the inspection and lubrication of components and the replacement and maintenance of damaged parts is to effectively ensure the working effect and good technical status of the excavator, to avoid the occurrence of failures due to the wear and tear of parts. Good security is provided. Omen characteristics: Rotating speed of diesel engine (gōngzuò) suddenly decreases, and the load increases.
The engine emits black smoke, the oil pressure drops (descend), and treatment measures (pointing to the solution to the problem): Immediately stop the machine, remove the connecting rod bushing, find out the cause, and omen characteristics: When the diesel crankshaft, journal, shoulder When fatigue causes hidden cracks, the symptoms of the failure are not obvious. As the cracks become heavier, a dull tapping sound is emitted in the crankcase of the engine. The tapping sound becomes heavier when the rotating speed changes. As the knocking sound gradually increased, the engine trembled, the crankshaft broke, and the measures (pointing to the solution to the problem): Immediately stop, Dali Carter excavator maintenance C9 engine low oil pressure fault analysis, 1 The oil quantity is insufficient 2 The oil pump is not rotating 3 The oil pump is worn 4 The engine oil temperature is too high 5 The gap between the main bearing shaft and the connecting rod bearing is increased 6 The bypass valve is damaged 7 The oil radiator is leaking Malfunction or oil passage clogging 9 Pressure limiting valve setting pressure is too low 10 Oil brand does not meet 11 Oil filter clogging 12 Set filter clogging Excavator maintenance Introduction of imported excavator hydraulic system Be comprehensive, systematic and specific. The structure and working principle of the pump, valve, motor, hydraulic cylinder and auxiliary components in the hydraulic system are introduced in detail, and the disassembly, repair and installation methods of each piece are described in detail. In each model, the electronic control system and fault diagnosis and elimination methods are also introduced systematically.
