Document Type and Number:
WIPO Patent Application WO/2017/048015
Kind Code:
The present invention relates to a rotary piston pump for collecting underground water located in a specific depth of a borehole, and the rotary piston pump according to the present invention allows: a plurality of volume varying spaces to be expanded or compressed by the rotation of a rotor such that a first inlet check valve and a second inlet check valve are in a closed state or an opened state of introducing, into a receiving part, underground water located in a borehole; and a first outlet check valve and a second outlet check valve to be in a closed state or in an opened state of discharging, to a ground connection pipe, the underground water located in the receiving part such that the underground water introduced into a rotor housing can be discharged in the ground. Since volume varying spaces are repeatedly expanded and compressed by the rotation of a rotor, the underground water is repeatedly suctioned and discharged, and at this point, high suction power is exhibited and, simultaneously, high pressure can be generated. In addition, since volume variations within a rotor housing simultaneously occur in three divisions, a large quantity of underground water can be drawn.
