Abstract
The utility model discloses a ceramic centrifugal pump which comprises a pump body, a pump cover and a motor, wherein the pump cover and the motor are arranged on the pump body. An impeller is arranged in the pump body, the ceramic centrifugal pump further comprises a shaft sleeve, the shaft sleeve and the impeller are formed integrally, the shaft sleeve penetrates through the pump body and the pump cover to be connected with an output shaft of the motor, the impeller comprises a main impeller and a hub, the main impeller and the hub are connected through a pin shaft, and ceramic layers are arranged on the outer surfaces of the main impeller and the hub. The ceramic centrifugal pump is resistant to abrasion and corrosion and prolongs service life at a certain extent.
Description
Technical field
The utility model relates to a kind of pump, is specifically related to a kind of ceramic centrifugal pump.
Background technique
Centrifugal pump is a kind of common fluid delivery system, and the pump housing, pump cover and impeller are the critical pieces in centrifugal pump.Traditional centrifugal pump middle pump body, pump cover and impeller are made by metal, wear no resistance, and very easily corrosion, working life is shorter.Therefore need often to change, thing followed operation expense has also uprised a lot.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of ceramic centrifugal pump is provided, and is wear-resistant, corrosion-resistant, extended to a certain extent its working life.
The technological scheme that the utility model adopts is: a kind of ceramic centrifugal pump, comprise the pump housing, be arranged at pump cover and motor on the pump housing, described pump body is provided with impeller, also comprise axle sleeve, described axle sleeve and impeller are one-body molded, and axle sleeve passes the pump housing and is connected with the output shaft of motor with pump cover, and described impeller comprises main impeller and wheel hub, described main impeller connects by bearing pin with wheel hub, and main impeller and hub outside surface are equipped with ceramic layer.
As preferably, described ceramic layer is oxide ceramic layer.
As preferably, described ceramic layer thickness is 2-5mm.
As preferably, described axle sleeve material is stainless steel.
The beneficial effects of the utility model are: main impeller and hub outside surface are provided with ceramic layer, and ceramic layer is wear-resisting, corrosion-resistant, have greatly strengthened the working life of centrifugal pump.Being connected by axle sleeve between motor and impeller realize, easy to connect, coupling stiffness is high, and good concentricity, and running is convenient.
