Excessive compressor lubricant consumption is mainly due to the following factors:

1. The lubricating oil is too thin (high oil temperature, the grade does not meet the requirements);

2. Lubricating oil pressure is too high;

3. The clearance between piston and cylinder is too large;

4 cylinder out of round or excessive wear;

5. Cylinder oil

(1) The piston ring is too abrasive and loses its elasticity;

(2) The piston ring bites in the ring groove;

(3) The piston ring groove clearance is too large;

(4) Install the wrong piston ring.

6. The crankshaft bearing or connecting rod bearing clearance is too large;

7. The crankcase temperature is too high or poor ventilation;

8. The lubrication rod lubricated by the splash lubrication method is too long or the crankcase oil level is too high.
