Excavator abnormal vibration how to do?
Posted: Nov 15th, '24, 01:58
1 Abnormal cab vibration, first check the four corners of the cab vibration device is loose, when the shockproof screw loose, the cab will be abnormal vibration, especially when the engine speed is relatively high, the cab and the glass around the shaking is particularly obvious. Therefore, fastening the damper screws eliminates vibration.
2 Abnormal vibration of the upper arm
Big arm shake, mostly from the cylinder sound, at this time you can check whether the big arm check valve hair clip wear, if the hydraulic oil through the valve core, and then driven to the big arm cylinder, the action will be inconsistent, the big arm vibration amplitude will increase with the frequency of action.
3 Rotation abnormal vibration
first
When there is a clomping sound in the rotating part, a slight vibration will be felt in the cab. This kind of vibration is caused by impurities between gears or gear breakage.
second
When rotating to a fixed position, there is abnormal vibration, indicating that the rotary motor is vibrating, it is recommended to check whether there are impurities or iron filings in the gear oil and lubricating butter.
4 Abnormal vibration of hydraulic pump
first
First check whether the main pressure is normal and whether it matches the engine power.
second
The two output tubing of the hydraulic pump shake, check whether the regulator is stuck, and check whether the safety lock solenoid valve switch is switched in place. Check whether there is metal powder in the hydraulic tank and the return oil filter to determine the wear condition of the plunger.
third
The pilot tubing jitter can check whether the pilot filter element and the joint with the filter screen are blocked, and can be cleaned regularly with diesel oil.
5 Abnormal engine vibration
first
First check whether the four engine foot pads are damaged, if so, the engine vibration will be unusually obvious.
Solution: Change the machine foot mat to ensure the balance of the engine.
second
When the engine starts, check whether there is a problem with the cylinder block. You can access Hino software to do a broken cylinder test, or touch the place where the high-pressure oil enters the cylinder block after the temperature is lowered to see if there is a temperature difference.
third
Confirm whether the nozzle and piston ring are worn. If the above two parts are damaged, the injection time and oil injection amount are inconsistent, which will also cause jitter.
