Symptom: There is a metal friction sound
Phenomenon: The exhaust emits black smoke, the power drops, and the supercharger has abnormal noise.
Cause:
1. If there is a metal friction sound, it is caused by excessive wear of the supercharger rotor bearing or thrust bearing, and the friction between the impeller and the supercharger shell.
2. If it is not a metal friction sound, but an air flow sound, it is due to the rotation sound generated by the high-speed rotation of the supercharger rotor, or the air leakage phenomenon caused by poor connection at the intake and exhaust interfaces.
Treatment:
(1) The former should be repaired by replacing the damaged spare parts according to the wear situation.
2. The latter should be carefully distinguished and addressed in a targeted manner.
Bearing damage
Phenomenon: the supercharger bearing is damaged, the engine power drops, the oil consumption is high, black smoke is emitted, and the supercharger cannot work in severe cases.
Cause:
1. Lubriing oil pressure and flow are insufficient.
Insufficient supply of lubriing oil to the supercharger journal and thrust bearing;
b. Insufficient lubriing oil to keep the rotor journal and bearings afloat;
c. The booster is running at high speed and the lubriing oil is not supplied in time.
2. Debris or sediment enters the lubriion system.
3. Oxidative deterioration of engine oil.
a. Diesel engine oil is overheated, and too much gas escapes between the piston and the cylinder wall;
b. Cooling water leaks into the oil;
c. Improper selection of oil, and failure to change oil regularly as required.
Treatment:
1. Check whether the lubriing oil pressure is normal and whether the amount of oil meets the requirements.
2. According to the requirements of the regulations, replace the lubriing oil regularly and ensure that the lubriing oil is clean.
3. In strict accordance with the requirements of the regulations, the use of lubriing oil, not mixed.
