[0023] The working principle of the utility model is:

[0024] By making the pump pool assembly 300 into an independent module and arranging it downward, the height difference between the bottom of the storage tank 202 and the top of the submersible pump pool 303 is increased, thereby increasing the static pressure head of the liquid at the inlet of the submersible pump pool 303.

[0025] The pump pool and pump pool pipeline are modularly designed and made into a lifting mechanism. During hoisting and transportation, the module is lifted to the level of the bottom beam of the main frame and the bottom beam of the pump pool module, and fixed with bolts. After the goods arrive at the site, the pump pool module is lowered to the level of the bottom beam of the main frame and the top beam of the pump pool module, and fixed with bolts. This structure is convenient for hoisting and transportation, and is also convenient for on-site installation, shortening the installation time.

[0026] The modular design of the pump pool and pump pool pipeline can meet the different configuration requirements (single pump, double pump) of customers. Each module is prefabricated in the factory and can realize various required functions through assembly and combination.

[0027] The refueling module comes with a canopy, breaking the conventional box-type LNG skid-mounted equipment structure. The overall appearance of the equipment is high-end and the operating space is larger.

[0028] The liquid outlet pipe of the storage tank extends from the cylinder body, which reduces the number of elbows in the internal pipeline of the storage tank, reduces the fluid resistance, makes the liquid inlet into the pump pool smoother, and is more conducive to the operation of the submersible pump.

[0029] The supercharger is integrated into the side wall of the main equipment. When transporting and hoisting, the supercharger module is pushed into the frame until it is flush with the side panel of the main equipment and fixed with bolts. After the goods arrive at the site, the supercharger module is pulled out, and after the bolts are fixed, the supercharger module is supported with a drawstring to increase the heat exchange space of the supercharger and facilitate defrosting and deicing.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
