FAQS
How to maintain the excavator's swing bearing?
Regularly lubricate the swing bearing, check if the grease is sufficient, inspect the bearing for wear or looseness, and adjust or replace it if necessary.
Why does the exhaust pipe emit blue smoke?
When the engine replaces new piston rings, pistons or cylinder liners, due to the initial poor running-in, it is easy for the engine oil to enter the combustion chamber and burn, producing blue smoke. This phenomenon can generally be gradually eliminated after running for 8-10 hours.
(1) The oil level in the oil pan is too high.
(2) The engine oil in the air filter leaks into the combustion chamber from the intake pipe and burns.
(3) The piston ring is bonded to the piston ring groove by carbon deposits, causing the engine oil to leak into the cylinder and burn.
(4) The piston ring is excessively worn, or when several piston rings are installed, the opening gap has been matched.
(5) The matching clearance between the piston and the cylinder liner is too large.
(6) The piston ring is not elastic enough.
How to address travel system issues in an excavator?
Inspect the tracks, travel motors, and travel reducers. Test the pressure and flow of the hydraulic drive system, check if the control valves are functioning correctly, and perform necessary repairs or replacements.
How do you prevent cavitation in a hydraulic pump?
Ways to prevent cavitation include maintaining the proper hydraulic oil level, using the correct oil viscosity, ensuring the filter is clean and avoiding excessive loads on the hydraulic system.
How to repair damaged hydraulic pump impellers?
Possible cavitation or debris in the oil.
Solution: Replace damaged impellers, prevent cavitation, filter oil.
