The NT855 diesel engine used in the D85A-18 bulldozer is weak and emits black smoke
Shut down and check, there is no oil leakage in the oil radiator, and there is no fault in the oil circuit. The engine was disassembled and inspected, and it was found that there were rust holes in the cylinder liner, which proved that the oil entered the water tank from the rust holes. The repair personnel believe that the failure phenomenon is caused by the large clearance of the cylinder wall, the too small compression ratio, and the incomplete combustion of the fuel. After replacing the cylinder liner, piston, piston pin and piston ring of the engine, when the engine was re-tested, black smoke was still emitted and the bulldozing was weak. The test of the injector shows that the fuel injection pressure is within the standard range and the atomization is good; no problem is found in the test of the PT pump. The engine was disassembled and inspected again, and it was found that there were no problems with the timing and piston rings, but when measuring the height of the camshaft cam, it was found that its height was only 2/3 of the standard height. Analysis believes that the height of the cam is reduced due to wear, so that the piston fails to burn when it moves to the top dead center position, resulting in a delay in ignition, making the engine emit black smoke and work powerless. After replacing the camshaft, the problem was eliminated.
The 6135AZKa diesel engine of Zhengshan brand T200 bulldozer has abnormal noise when working
When dismantling and inspecting the engine, it was found that the connecting rod bolts of the IV cylinder have been stretched a lot. It is preliminarily concluded that the cause of the failure may be that the connecting rod bolts are loose, resulting in increased force and deformation under repeated impact; it may also be that the connecting rod screw has a quality problem . For this purpose, other connecting rod bolts were checked, and the results were no problem, and their tightening torques also met the requirements. After replacing this connecting rod bolt, the installation and operation show that everything is normal, and the fault is eliminated. Later, it was learned that the connecting rod of the IV cylinder was slightly deformed during the overhaul of the machine, and the repair personnel carried out the assembly after self-correction.
Therefore, the real reason for this failure is that the deformation of the connecting rod will cause the connecting rod bolts to undergo plastic deformation, resulting in a decrease in its tensile strength. assembly, resulting in bolt elongation due to reduced tensile strength.
TATRA3-929-11 Diesel Engine for TATRA815S1 Dump Truck Occurs on Squeeze
After the machine was overhauled, it only ran for 1000h before the tile-holding phenomenon occurred. After dismantling the engine, the engine oil was first checked. The engine uses Great Wall 15W/40CD engine oil. Although the viscosity of the engine oil is reduced at high temperature, it is within the normal value, and the pollution degree, suspension, pH value, etc. are all qualified; check again. The oil circuit is also unobstructed and there is no oil leakage. When the oil pump was dismantled and inspected, it was found that the gap between the end face of the gear and the front and rear covers was too large, resulting in internal leakage. Since the aluminum pump casing cannot be repaired with a grinder, it is processed with a plane milling machine to make the gap between the end face of the gear and the front and rear covers reach the standard value, and then polished with metallographic sandpaper. After re-installation, there is no internal leakage during the test, and the work has been normal in subsequent shipments, indicating that the fault has been eliminated.
The analysis believes that the reason for this failure is that the engine was overhauled in the spring when the temperature was low, and the oil viscosity was high at that time, so the oil pump leakage was small, and the oil pressure could reach the normal value, so the maintenance personnel ignored the oil pump. During construction in summer, the continuous operation of the machine at high temperature reduces the viscosity of the oil, increases the internal leakage of the oil, and fails to form an effective oil film, which leads to a tile holding accident.
