AI Technical Summary

Technical Problem

Existing composite insulated oil tanks can only be set up as a single tank and cannot be spliced ​​together, resulting in a small oil storage capacity and requiring additional oil storage equipment.

Method used

Design a modular composite insulated fuel tank, which adopts a main fuel tank and a secondary fuel tank structure, and is spliced ​​by docking grooves and connecting pins. It is equipped with a fuel replenishment pump and an insulation layer, and uses a polyurethane foam layer to improve the insulation performance. The fuel balance is maintained by a float fuel gauge and a fuel replenishment pump.

Benefits of technology

It enables flexible expansion of the fuel tank, increases fuel storage capacity, maintains stable fuel temperature, prevents fuel shortage, and improves usage flexibility and heat preservation effect.
