Common methods to solve the black smoke of excavators
General method for solving black smoke color of foundation pit
After explaining the cause of the failure of the smoke excavator, this article tells you how to treat the failure and solve the smoke. Common excavator structures for repairing excavators include power units, work units, slewing mechanisms, operating mechanisms, transmission mechanisms, walking mechanisms, and auxiliary facilities. Excavator repairs The materials excavated by the excavator are mainly soil, coal, silt, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction.
Treatment method for white smoke from excavator:
The white smoke is caused by poor atomization or oil droplets of the injector of the excavator, which causes the diesel part to not burn; diesel has water supply; there are no visible cracks in the cylinder head and cylinder liner, and the cylinder gasket is damaged, leaving water in the air cylinder; The temperature of the machine is too low.
Solution: Clean or replace the injector, adjust the injection pressure; clear oil and water in the water tank, do not buy cheap and inferior oil; replace the cylinder head gasket, cylinder liner, cylinder head; resolve it after running for a while.
Excavator smoke control method:
First, the excavator produces black smoke due to long-term overload operation of the engine, serious carbon deposits in the combustion chamber, abnormal operation of the fuel injector, too late fuel supply time, untimely combustion, excessive fuel supply, and diesel quality not meeting the requirements; Valves, cylinder liners, piston rings, piston rings and other abrasion gases and gases; the intake pipe is blocked, resulting in insufficient intake air, and exhaust gas is inexhaustible.
Common treatment methods: clear the carbon deposits in the combustion chamber; adjust the gasket of the fuel injection pump to make the fuel supply advance angle meet the requirements; repair the grinding valve or replace the cylinder liner, piston and piston ring; adjust the fuel supply of the fuel pump and replace the fuel that meets the requirements Requirements; clean the air filter and remove carbon deposits from the muffler
Processing method of blue smoke of excavator
The blue smoke of the excavator is because the oil enters the combustion chamber to participate in the combustion, the piston ring and the cylinder liner are not running in, and the oil enters from the gap; the piston ring is glued in the groove, and the tapered surface of the piston ring is reversed, losing the role of oil scraping; the piston The ring wears too much, and the oil runs into the combustion chamber from the opening gap; the oil level of the oil pan is too high; the air filter oil is too much; the valves and ducts are worn, and the gap is too large.
Solution: The new or overhauled locomotive must run in the engine in accordance with the regulations so that the parts can mesh properly; see the assembly mark and install the piston ring correctly; replace the piston ring that is qualified or oversized; check the oil level of the oil pan The reason for the rise is to release excess oil from the oil pan; reduce the oil in the filter pan; replace the valve guide.
