Description

The main oil cylinder of the pile frame of an ultra-large pile driving vessel is a core component of a large pile driving vessel. The main oil cylinder of the pile frame of an ultra-large pile driving vessel works with a long stroke, which is likely to cause the eccentric load failure of the oil cylinder seal; the piston rod of the oil cylinder is exposed to the marine environment for a long time, which is likely to cause failures such as rust, resulting in seal failure and oil leakage problems. If it is not repaired in time until the oil cylinder cannot move or suddenly fails, it will cause expensive maintenance costs and even serious safety accidents.
