Detailed Description

The utility model is described in further detail below with reference to fig. 1-5:

as shown in fig. 1 to 5, a two-stage high-level fuel tank apparatus includes a tank body 1, a fuel level gauge 2, an oil inlet joint 3, an oil supply joint 4, an oil return joint 5, and an overflow joint 6; the inside of the box body 1 is in a hollow shell shape, and the appearance is in a cuboid structure; the same side of the upper end and the lower end close to the edge is provided with a hanging lug for installation, and the hanging lug is provided with a positioning hole; the oil inlet joint 3 is arranged on the left side below the box body 1 and is communicated with the box body 1; the oil supply joint 4 is arranged on the right side below the box body 1 and is communicated with the box body 1; the oil return joint 5 is arranged below the right side surface of the box body 1 and is communicated with the box body 1; the overflow joint 6 is arranged above the side surface of the box body 1 and is communicated with the box body 1; the overflow joint 6 and the return joint 5 are provided on the same side.

As shown in fig. 1 and 2, the oil level observation table 2 is mounted on the side opposite to the side where the overflow joint 6 is located, and the upper and lower parts Fang Jun thereof are communicated with the tank 1 to form a communicating vessel, and the oil level in the tank 1 can be obtained in real time by observing the oil level in the tank 2.

As shown in fig. 2, the inside of the box body 1 is further provided with an oil baffle plate 11, one end of the oil baffle plate 11 is connected with the side surface of the box body 1, which is provided with the oil return joint 5, the connecting position is located below the oil return joint 5, the horizontal position of the other end of the oil baffle plate 11 is higher than the connecting position, and the oil baffle plate 11 is connected with the intersecting side surface in an inclined manner inside the box body 1.

The working principle of the two-stage high-level fuel tank device of the utility model is as follows:

the electric fuel pump sucks fuel from the first-stage fuel tank and sends the fuel into the fuel inlet joint 3, the oil in the tank 1 is connected into the fuel pipe of the engine through the joint 4, the fuel returned by the engine is connected into the tank 1 again through the joint 5, when the liquid level in the tank 1 is higher than the height of the overflow joint 6, the fuel overflows back to the first-stage fuel tank; therefore, the low-level fuel oil can be changed into high-level fuel oil, the whole layout is not greatly changed, the phenomenon that the engine work is affected due to suction air generated during shaking can be prevented, and the fuel oil quantity in the box body 1 can be known in real time by observing the oil level height of the oil level observation meter 2.

The foregoing is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model, for the purposes of describing the present utility model, and is to be construed as limited only by the appended claims.
