摘要: Disclosed herein is a tank-pump integrated structure for an LNG filling station, which comprises a tank body having heat insulation layer space, a siphon package at the bottom of the tank body and a pump sump arranged in the siphon package. Moreover, a first heat insulation pipeline in the siphon package is connected to an LNG inlet on the pump sump, and a gas return port of the pump sump is coupled with the tank body by means of a second heat insulation pipeline. An on-off valve is arranged on the first heat insulation pipeline between the tank body and the pump sump, a shut-off valve is additionally arranged on the second heat insulation pipeline between the gas return inlet and the tank body, and heat insulation devices are provided external to the on-off valve and the shut-off valve respectively. The integrated structure can reduce investment costs, shorten the construction period, and facilitate maintenance of the submersible pump via the valves.
