Abstract
A ceramic pump shell with a protective iron shell belongs to the manufacture field of a ceramic pump. The ceramic pump shell with a three-part type structure is fully made of ceramic materials; a matched front protective iron plate (2), a matched rear protective iron plate (4) and a matched protective bush iron shell (6) are sequentially arranged on the outer surfaces of a ceramic front protective plate (1) with a serous flux inlet (9), a ceramic rear protective plate (3) with a rotary shaft hole (10) and a ceramic protective bush (5) with a serous flux outlet (11) respectively; and middle packing layers (7) are arranged between the front protective iron plate and the ceramic front protective plate, between the rear protective iron plate and the ceramic rear protective plateas well as between the protective bush iron shell and the ceramic protective bush. Therefore, corresponding stress loaded by the three parts in the mounting and running process can be effectively resisted; the ceramic pump shell is not easily damaged, so that the finished product rate of the ceramic pump shell and the production rate of ceramic pumps are improved.
Description
Technical field
The utility model belongs to ceramicpump and makes the field, relates to a kind of ceramic pump case with the protection iron-clad.
Background technique
In the prior art, ceramic pump case with the three component type structures that all are the stupalith manufacturing, so-called three parts are, the apron plate of band slurry inlet, the sheath (spiral case) of the back backplate of band rotary shaft hole and the outlet of band slurries, and three parts process for integral body respectively, its deficiency is, three parts are in installation process, before, back backplate is easily because extrusion stress is unbalanced and damaged by pressure in opposite directions, sheath is because before being subjected to, the back extruding, produce tensile stress at the sheath hoop, this power makes the sheath initial ring to fracture easily---and be that sheath is broken due to the tensile stress, and in running, under the pressure effect of slurries, also produce tensile stress, and make the sheath initial ring easily to fracture at the sheath hoop.
Summary of the invention
The technical problem that solves:
Adopt the ceramic pump case of band protection iron-clad; can overcome the deficiencies in the prior art; forward and backward backplate and sheath are with the protection iron-clad respectively; can effectively resist the suffered unbalanced extrusion stress of forward and backward backplate in the installation; can effectively resist the tensile stress that produces at the sheath hoop in installation and the running; thereby make forward and backward backplate and sheath not fragile in installation and running, thereby improve the yield rate and the ceramic capacity of pump of ceramic pump case.
The technological scheme that adopts:
The ceramic pump case of band protection iron-clad, comprise the ceramic apron plate of being with slurry inlet, the pottery back backplate of band rotary shaft hole and the ceramic sheath of band slurries outlet, it is characterized in that: have supporting preceding break iron plate, back break iron plate and sheath iron-clad successively respectively on the outer surface of described ceramic apron plate, pottery back backplate and ceramic sheath, have the supporting packing layer that producing balanced forces has reached buffer function that is used for respectively reaching between sheath iron-clad and the described ceramic sheath between the backplate between preceding break iron plate and the described ceramic apron plate, behind back break iron plate and the described pottery; Preceding break iron plate, back break iron plate are fixed together by fastening piece and described ceramic apron plate, pottery back backplate respectively.
Beneficial effect:
Owing to have supporting protection iron-clad respectively on the outer surface of ceramic apron plate, pottery back backplate and ceramic sheath (spiral case); and intermediate filler layer is arranged all; therefore; can effectively resist three parts suffered corresponding stress in installation and running; make it not fragile, thereby improve the yield rate and the ceramic capacity of pump of ceramic pump case.
