【Q&A Question 259】September 22, 2018: Briefly explain the reasons for excessive lubricant consumption in compressors. The excessive consumption of compressor lubricant is mainly due to the following factors: 1. The lubricant is too thin (high oil temperature, incorrect grade) ； 2. Excessively high lubricating oil pressure ； 3. The gap between the piston and the cylinder is too large ； 4. Cylinder out-of-roundness or excessive wear ； 5. Oil leakage in the cylinders: 6. Excessive clearance in the crankshaft bearings or connecting rod bearings ； 7. Excessively high crankcase temperature or poor ventilation ； 8. The pump rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

The main problems are as follows:； The lubricating oil is too thin, or the lubricating oil pressure is too high ； There is also an excessive gap between the piston and the cylinder, as well as a misshapen cylinder or excessive wear ； It is certainly possible for oil to leak between the cylinders: this is due to excessive wear of the piston rings, which causes them to lose their elasticity ； The piston ring is stuck in the ring groove ； The clearance in the piston ring groove is too large, and the piston rings are installed incorrectly. Excessive clearance in the crankshaft bearings or connecting rod bearings, high crankcase temperature, or poor ventilation ； The pump rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high.
1. The lubricating oil is too thin, or the lubricating oil pressure is too high； 2. Excessive clearance between the piston and the cylinder, as well as cylinder out-of-roundness or excessive wear ； 3. Oil leakage in the cylinder: The piston rings are excessively worn and have lost their elasticity ； 4. The piston ring is stuck in the ring groove ； 5. The clearance in the piston ring groove is too large; the piston rings are installed incorrectly ； 6. Excessive clearance in the crankshaft bearings or connecting rod bearings, high crankcase temperature, or poor ventilation ； 7. The grease rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high.
The lubricating oil is too thin, or the lubricating oil pressure is too high； There is also an excessive gap between the piston and the cylinder, as well as a misshapen cylinder or excessive wear ； It is certainly possible for oil to leak between the cylinders: this is due to excessive wear of the piston rings, which causes them to lose their elasticity ； The piston ring is stuck in the ring groove ； The clearance in the piston ring groove is too large, and the piston rings are installed incorrectly. Excessive clearance in the crankshaft bearings or connecting rod bearings, high crankcase temperature, or poor ventilation ； The pump rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high.
1 Leakage in the seal 2 High oil return temperature leading to evaporation 3 Leaks inside the cooler also increase consumption

Excessive clearance in the crankshaft bearings or connecting rod bearings, high crankcase temperature, or poor ventilation ； The pump rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high.
There are many places where the compressor leaks oil； The lubricating oil is too thin, or the lubricating oil pressure is too high ； There is also an excessive gap between the piston and the cylinder, as well as a misshapen cylinder or excessive wear ； It is certainly possible for oil to leak between the cylinders: this is due to excessive wear of the piston rings, which causes them to lose their elasticity ； The piston ring is stuck in the ring groove ； The clearance in the piston ring groove is too large, and the piston rings are installed incorrectly. Excessive clearance in the crankshaft bearings or connecting rod bearings, high crankcase temperature, or poor ventilation ； The pump rod lubricated by the splash lubrication method is too long, or the oil level in the crankcase is too high.
