AI Technical Summary
In the prior art, the cooling oil drain pipe of marine diesel engine piston is prone to thermal expansion and deformation under high temperature environment, resulting in insufficient straightness and inability to effectively resist thermal expansion and deformation, increasing the risk of collision with moving parts.
An adjustable bracket is used, including a welded support plate, an adjustable support plate, locking washers, and hexagonal bolts. The connection and locking washers are made through threaded holes to increase the contact area and lateral support. Thermal expansion holes are reserved to absorb displacement and reduce the risk of collision.
It effectively reduces the risk of collisions caused by thermal expansion and deformation, ensuring the safe operation of the diesel engine and reducing noise and wear.
