Claims

[Scope of utility model registration request]

The center of the lid-like closed surface of a short large-diameter pipe is opened and the discharge pipe is joined to form an irregularly shaped pipe.
The discharge side has a flange attached to the outer periphery of the fully open side of the large-diameter pipe (Fig. 1), and the suction pipe has an outer diameter smaller than the inner diameter of the discharge pipe by a predetermined dimension.
A flange of the same standard as the discharge side is installed on the outer periphery of the point at which the tube slides inward from the tip by a predetermined distance (corresponding to a point that slightly exceeds the length of the large-diameter pipe on the discharge side). (Fig. 5) are connected by respective flanges (Fig. 5). At this time, the tip of the suction pipe airtightly penetrates into the large-diameter pipe on the discharge side and enters the inside of the inlet of the discharge pipe by a predetermined length, A thin, uniform gap is created between the inner circumferential wall of the discharge pipe and the outer circumferential wall of the suction pipe, creating a circumferential injection space (Fig. 6), and the outer circumferential wall of the suction pipe and the large-diameter pipe on the discharge side are penetrated. A hole having a predetermined diameter is opened in a part of the outer wall of the large-diameter pipe, which communicates with the wide donut-shaped space (Fig. 5) formed between the pipe and the inner circumferential wall of the pipe. A circumferential injection jet pump characterized in that it is configured to be installed at a position according to specifications, as shown in FIG. 1 or FIG. 7.
