Abstract
An impact well configured to reduce the turbulence in a flowing fluid. The impact well has the shape of a frustum and includes an upper portion, an intermediate portion and a base portion. The base portion includes a domed portion that extends upwards into the intermediate portion. The upper portion, the intermediate portion and the base portion each included stepped areas configured to assist in the alignment of the portions and the assembly of the well.
Claims20
An impact well configured to reduce the turbulent flow of a fluid being added to the well, the well comprising:
- a base member including a domed portion;
- an upper member shaped like a frustum;
- and
- an intermediate member shaped like a frustum and the upper member positioned on the intermediate member and the intermediate member positioned on the base member, wherein the upper member includes an upper portion and a side portion, the upper member defining an opening and the side portion defining four sides, the intermediate member includes an upper portion and side portion, the upper portion of the intermediate member including a stepped portion configured to engage a stepped portion formed in a bottom surface of the side portion of the upper member, and the upper portion of the intermediate portion including a projection extending inwardly into a receiving area, a top of the domed portion extending upwardly beyond a bottom side of the projection.
A method of filling an impact well having the shape of a frustum comprising an opening, a receiving area below the opening, and a contoured portion, including the steps of:
- providing a casting mold having a cavity;
- locating the impact well in the cavity;
- locating a shroud configured to dispense a fluid above the contoured portion of the impact well;
- providing the impact well with a bottom and side walls without openings so the well will contain the fluid therein;
- locating a bottom of the shroud below the opening of the impact well and within the receiving area;
- and
- dispensing the fluid from the shroud so that the fluid fills the receiving area and flows out the opening into the cavity.
An apparatus for reducing the turbulent flow of a fluid including:
- a side portion defining a receiving area;
- a top portion defining a top opening;
- a base including a contoured top surface;
- and
- a projection extending into the receiving area from the side portion, the projection defining an intermediate opening, the intermediate opening having a larger diameter than the top opening.
