Embodiment Construction

[0025] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Certain electromechanical products 1 powered by gasoline, diesel and other liquid fuels contain elastic bag components in the rigid fuel tank 2 for storing fuel, and the fuel is stored in the elastic bag 3. The rigid fuel tank 2 is filled with high-pressure gas, and the fuel oil in the elastic bag 3 is squeezed by pressure, so that the fuel oil can continuously and stably flow to fuel-consuming equipment to provide fuel for fuel-consuming equipment such as the internal combustion engine 4 .

[0027] This embodiment proposes a vacuum-type fuel filling method for a fuel tank containing an elastic bag. The vacuum-type fuel filling system used in the method includes an oil storage tank 5, a filling gun 6, a discharge ...

Abstract

The invention proposes a vacuum-pumped fuel filling method for a fuel tank with an elastic bag, which includes preparation before filling, inflating the rigid fuel tank to a specified pressure, and vacuuming the elastic bag to make the inside of the elastic bag reach a specified vacuum state, fill the elastic bag with fuel, fill the fuel tank with fuel, calculate the reserved air cushion amount ΔV, discharge fuel, reserve air cushion ΔV, and withdraw after filling. The method can reliably and practically realize the work of filling the fuel tank and reserving the air cushion, and provides a useful reference for similar products to perform the work of filling the fuel.

Description

technical field [0001] The invention belongs to the technical field of fuel filling, and in particular relates to a vacuum-pumped fuel filling method for a fuel tank containing an elastic bag. Background technique [0002] Fuel filling is an essential process for electromechanical products powered by internal combustion engines. Depending on the structure of the fuel tank, the method of fuel filling for electromechanical products is also different. According to the difference in the internal structure of the fuel tank, it is divided into a fuel tank with an elastic bag and a fuel tank without an elastic bag. The oil tank with elastic bag is divided into the method of filling oil in the elastic bag and filling oil outside the elastic bag. [0003] The fuel filling process of the fuel tank with the fuel in the elastic bag is relatively complicated. It is necessary to ensure that the elastic bag is completely filled with fuel, and a certain amount of inert gas must be filled ...
