Detailed Description
The present utility model will be further described below.
Referring to the drawings, a vertical rotary jet pump is characterized in that: including main shaft 1, rotary drum 7, coupling head 10, collector tube 3, be provided with rotor lid 9 on the rotary drum 7, form rotor chamber 5 between rotary drum 7 and the rotor lid 9, be provided with runner 91 in the rotor lid 9, be provided with movable ring seat 12 on the rotor lid 9, be provided with cavity 8 between the interior circle of movable ring seat 12 and the outer circle of collector tube 3, the inlet 4 of collector tube 3 is located rotor chamber 5 top.
In the preferred embodiment, one end of the liquid collecting tube 3 is positioned in the rotor cavity 5, and the other end is communicated with the pump outlet 2.
In the preferred embodiment, the inlet 11 of the coupling head 10 communicates with the cavity 8, the flow channel 91, and the rotor chamber 5.
In the preferred embodiment, the upper inner surface of the drum 7 is tapered.
In specific implementation, the pump starts the liquid inlet and exhaust process as follows:
a. the pump outlet valves are opened and the pump inlet valve is opened to let the pressurized liquid from the inlet 11 of the coupling head 10 through the liquid collecting pipe 3 and the cavity 8 of the movable ring seat 12 into the flow channel 91 of the rotor cover 9.
b. Pressurized liquid enters the rotor chamber 5 from the rotor cover, and air in the rotor chamber 5 is discharged from the liquid inlet 4 of the liquid collecting pipe 3 at the upper part into the outlet pipeline of the pump through the pump outlet 2. The liquid collecting pipe is inclined to the horizontal plane, so that the inlet part of the liquid collecting pipe is positioned at the top of the rotor cavity. The conical structure of the upper inner surface of the drum 7 minimizes the remaining cavity of the liquid collecting pipe, which is located at the upper part of the inlet of the liquid collecting pipe and is fed by the pump.
c. When the liquid level reaches the uppermost edge of the inlet of the liquid collecting pipe, air in the pump cavity is not discharged any more, and after the liquid is started, the liquid is mixed with the residual air 6 by virtue of centrifugal force generated by rotation of the conveyed liquid, so that the air is discharged, and the vertical rotary jet pump can reach the specified performance in the shortest time.
The foregoing embodiments of the present utility model are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model, and all equivalent technical solutions are also included in the scope of the present utility model, which is defined by the claims.
