1. The bearing and the journal are not evenly attached or the contact surface is over. ㄅ浜霞湎豆. The ノ ノ ノ 谋 谋 妊 妊 妊 妊 妊 妊 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 2. The bearing is skewed or the crankshaft is tortuous and distorted.
3, the quality of the bearing bush is not good; the quality of the lubricating oil does not match (viscosity. Change the venting of the chlorine. The oil pressure of the gear oil pump is too low; and the oil supply is suspended; the bearing bush is short of oil;
4. There are too many impurities or lubricating oil in the bearing; or the lubricating oil is too dirty.
5. The bearing bush has uneven wear and tear.
6. When the compressor is installed, the spindle and the motor (or diesel) spindle coupling are not aligned; the error is too large; the two axes are skewed.
Cleaning method:
1. Scrape the bearing bush with the coloring method; make the contact surface meet the demand; improve the specific pressure per unit area,
2, properly adjust the cooperation gap; view the crankshaft twists and turns, distortion status; change the new crankshaft or repair according to the situation,
3. Use the bearing bush that fits the quality; view the oil pipeline and the gear oil pump; use the lubricating oil that meets the quality requirements; check and adjust the oil pump to make the pressure reach the demand.
4. Remove and replace the new engine oil; adjust the oil pressure,
5. Replace the new bearing bush,
6, the two machines concentricity should be positive, leveling its public service value should match the value of the machine manual rules. Especially when the compressor and motor are connected with rigid connection; more attention should be paid to alignment.
