Abstract
PURPOSE: To facilitate fine adjustment of a mud return by an arrangement wherein an air passage through to the atmosphere is connected to the back of impeller and a draft regulating mechanism is provided is said air passage.
CONSTITUTION: An air passage 5 through to the atmosphere is connected to the back of an impeller 2, and a draft regulating mechanism 6 is provided in said air passage 5. At the time of pump operation, air in the atmosphere passes the air passage 5, flows into a vortex chamber 1 from the back of impeller 2 through a vane opening air passage 2a and is sucked through an inlet port 3 to mix in a mud sent to a pumping-up pipe 4 by a vane opening air passage 2b, thus decreasing the mud returned from the pumping-up pipe 4. With the running speed of a motor remaining unchanged, the mud return can be adjusted simply by adjusting self- sucked air quantity through operation of the draft regulating mechanism 6, thereby facilitating fine adjutment of the mud return.
