The invention discloses a ship fuel supply system which comprises a fuel storage tank T. A centrifugal fuel pump P is arranged in the fuel storage tank T. The centrifugal fuel pump P inputs LNG in the fuel storage tank T into a low-temperature vacuum pump pool D through an ultralow-temperature pipeline, and a high-pressure fuel pipeline and a low-pressure fuel pipeline are arranged on the downstream of the low-temperature pump pool D. According to the invention, the low-temperature pump belongs to a hydraulic pump, the whole hydraulic pump is installed in the pump pool, no medium leaks, the system cooling capacity loss is effectively reduced, the vaporization amount is reduced, optimization of the working condition during operation of the cryopump is facilitated, and the pressure storage time of a storage tank is effectively prolonged.

    本发明公开了一种船舶燃料供给系统,包括燃料储罐T,所述燃料储罐T内设有离心燃料泵P,所述离心燃料泵P将所述燃料储罐T中的LNG通过超低温管线输入至低温真空泵池D中,所述低温泵池D下游设有高压燃料管路和低压燃料管路。本发明的低温泵属于液压泵,所述液压泵整机安装于所述泵池内,且介质无泄漏,有效降低了系统冷量损失,减少汽化量,有助于低温泵运行时工况的优化,有效延长储罐的蓄压时间。
