Damage To The Piston Ring Of Marine Engine Parts Can Easily Cause Fluid Accumulation In The Cylinder

2021-09-14

 

Damage to the piston ring of marine engine parts can easily cause fluid accumulation in the cylinder of the marine diesel engine. Therefore, you must pay more attention to it! Next, let's understand the cause of the failure with the staff of Changsha Haochang Machinery Equipment Co., Ltd.!

The lubrication of the cylinder of the marine engine parts adopts splash lubrication. The rotation of the crankshaft drives the connecting rod to swing to throw the oil on the cylinder wall.

The ship engine parts piston is equipped with 5 piston rings, the top of the piston is equipped with 3 sealing rings, and the piston skirt is equipped with 2 oil scraping rings. The correct installation method of the oil scraper ring is that the tip of the scraper is facing downwards, so that the oil is distributed when the piston moves up, and the oil is scraped when it moves down. If the installation direction is reversed, the opposite effect will be produced when the piston moves, pumping a large amount of oil into the cylinder. To cause fluid accumulation in the cylinder.

In addition, the piston ring of marine engine parts reciprocates with the piston in the cylinder. If the piston ring is excessively worn, a large gap will be formed between the piston ring and the cylinder liner. The diesel engine throws the oil on the cylinder wall during operation, and the gap between the piston ring and the cylinder liner is too large, and the oil cannot be scraped normally, which will cause the oil to run up and form oil accumulation in the cylinder.

After removing the ship engine parts piston, put the removed piston ring horizontally into the cylinder liner, and measure the outer circle clearance as required to see if the clearance is too large. If this happens, replace it in time.

In short, excessive wear of the piston ring of marine engine parts will cause fluid accumulation in the cylinder of marine diesel engine.
