Abstract
The utility model discloses a stamping pump cavity which comprises a revolving shaft and a cavity body. The cavity body is of a half ball shape. A connecting block is arranged on the cavity body. The cavity body is fixedly connected with the revolving shaft through the connecting block. An impeller is arranged at the inlet position of the cavity body, and is connected with the cavity body in a welding mode. Compared with an existing stamping pump cavity, the cavity body is of the half ball shape, and therefore the energy loss is reduced in the process of destabilization. Due to the fact that the cavity body is provided with the connecting block, and is fixedly connected with the revolving shaft through the connecting block, the connection is firm. The impeller is arranged at the inlet position of the cavity body. An installation angle of a water inlet of the impeller is between 20 degrees and 25 degrees, and an installation angle of a water outlet of the n impeller is between 15 degrees and 30 degrees. Water can flow into the cavity conveniently, and working efficiency is high.
Description
Technical field
The utility model relates to a kind of stamping pump, relates in particular to a kind of stamping pump pelvic cavity.
Background technique
Present stamping pump pelvic cavity complex structure, inefficiency is though lift height flow is really less.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of stamping pump pelvic cavity that has solved above problem.
The technical solution of the utility model is: a kind of stamping pump pelvic cavity, comprise rotating shaft and pelvic cavity body, described pelvic cavity body is hemisphere, described pelvic cavity body is provided with contiguous block, described pelvic cavity body is fixedly connected with rotating shaft by contiguous block, described pelvic cavity body ingress is provided with impeller, described impeller and the welding of pelvic cavity body.
As preferably, described impeller is circular arc, and is three to eight.
