1 Out in the shaft loaded oil ring groove or by centrifugal force along the axis of the oil drain off the surface, the oil flows back to the assembly after the pool, and thus play a role in sealing.

2 Water pump housing, Hubs, Bearing housing, Dampers hub oil ring, sector shaft, oil pump cover, water in let and outlet, vacuum pump .

3 Oil ring slots, or holes , must be clean; a drill of the proper size is handy for this job.

4 Comparison with the chromium-plated oil ring, the niobium cast iron oil ring had lower cost, excellent wear resistance and no contamination from chromium plating.

5 The test results indicated that the controlling of oil consumption, wear of cylinder and the oil ring were satisfactory. The Developed oil ring has been adopted on the CA6102 gasoline engine.

6 The Yingmai 7-19 is a condensate gas reservoir with edge water and oil ring which was developed by a set of failure well pattern.

7 It not only provides approach of rebuild electromotive motor, but also offers an actual proof of expanding use of oil ring bearing and research of lubricate theory.

8 In this paper, the design basis, calculation method and construction feature of the new type composite oil ring with helical spring used in the medium and high speed diesel engine are described.

9 The results also find that wear resistance of niobium cast iron oil ring is 87.3% higher than that of CrMoCu alloy cast iron along with the cost reduction for niobium cast iron oil ring.

10 Baimiao field, located in the southern part of Dongpu depression, is mainly a condensate gas field, with oil ring at the bottom.

11 Further understanding of the mechanism of lubrication, friction and oil-scraping action of oil ring is gained from studying on oil-scraping height of the coil spring loaded oil control ring.

12 Based on the bedding grid and horizontal grid, mixed grid-modeling method was established by analyzing oil ring distribution and the existing reservoir simulation grid technique.

13 The lower one prevents the oil splashed onto the cylinder bore from entering the combustion chamber, and is called an oil ring.

14 More importantly, it is the first time for the police to dismantle a nationwide illegal cooking oil ring, which confirms the rumors that many restaurants in China use gutter oil to cook food.
