Embodiment

Below in conjunction with accompanying drawing and specific implementation process, the present invention is elaborated.

See accompanying drawing, a kind of hydro powered type water pump, is made up of cement pedestal 1, pre-embedded bolt 2, pad 3, nut I4, support 5, screw I6, seal ring I7, bearing I 8, gear I9, floating slice I10, gear II11, bearing I I12, bonnet 13, floating slice II14, bearing I II15, seal ring II16, seal ring III17, impeller 18, back-up ring 19, jump ring 20, nut II21, flat key 22, safety cover 23, screw II24, bearing I V25, protecgulum 26, water absorbing filter 27, pipe joint 28, high-pressure water pipe 29; Described impeller 18 is arranged on the axle of gear II11, and middle installation flat key 22 transmitting torque, has back-up ring 19 to prevent impeller from moving to left on the left of impeller 18, mounting nuts II21 on the right side of impeller 18, prevent impeller 18 from moving to right, jump ring 20 is housed on the right side of nut II21, prevent nut II21 from loosening.

Described gear I9 and gear II11 is a pair duplicate stainless steel gear pair of profile of tooth, gear I9 respectively installs bearing I8 and bearing I V25 in both sides, bearing I 8 is arranged on bonnet 13, bearing I V25 is arranged on protecgulum 26, gear I9 can be rotated for a long time in water, gear II11 respectively installs bearing II12 and bearing I II15 in both sides, bearing I I12 is arranged on bonnet 13, bearing I II15 is arranged on protecgulum 26, gear II11 can be rotated for a long time in water, gear mesh both sides are provided with floating slice I10 and floating slice II14, can play seal action.
