AI Technical Summary
Traditional oil tank cores use a metal corrugated hose to connect the exhaust port on the upper end plate to the exhaust pipe at the bottom of the tank, which is easily damaged and requires a handhole or manhole for installation and maintenance.
A linkage mechanism consisting of a rotary sealing joint and connecting pipe is used to replace the traditional metal corrugated hose connection method, so as to realize the synchronous operation of the upper end plate of the oil tank core and the exhaust pipe.
This improved the reliability of the structure, reduced the risk of damage, decreased the height of the oil tank, and lowered the cost.
