The object of the present invention is to provide anticorrosive, high temperature resistant, the long service life of a kind of use, easy to maintenance, the big plastics magnetic drive pump of carrying moment.
Plastics magnetic drive pump of the present invention, comprise pump case, motor, carriage, pump shaft, be installed in impeller and interior coupling on the pump shaft respectively, and outer coupling, interior coupling, be provided with separation sleeve between the outer coupling, middle body is installed on the ear end face of described pump case, the other end of middle body is equipped with suspension, in the chamber of body, the end that pump shaft is positioned at described suspension was equipped with described coupling during described pump shaft can be installed in rotationally, and suspension is fixed on the described carriage, described impeller adopts metallic material to make, its outer surface is coated with fiber-reinforced resin layer, and described separation sleeve adopts fiber-reinforced resin to make, and which is provided with the metal strengthening net, described pump shaft adopts metallic material to make, and its outer surface is coated with fiber-reinforced resin layer.
Plastics magnetic drive pump of the present invention, wherein said outer coupling is installed on the transmission shaft, and transmission shaft can be installed on the described suspension rotationally, and transmission shaft is positioned at the outer end of suspension coupling is installed, and coupling links to each other with the motor shaft of described motor.
On the end face of body, pump shaft adopted two sliding bearing installing and locating respectively during plastics magnetic drive pump of the present invention, wherein said separation sleeve adopted and be bolted to, and described transmission shaft adopts two rolling bearing installing and locating respectively.
Plastics magnetic drive pump of the present invention is coated with resin layer on the madial wall of wherein said pump case and described middle body.
Plastics magnetic drive pump of the present invention, wherein said interior coupling is coated with fluororesin.
Plastics magnetic drive pump of the present invention, wherein said middle body adopts bolt to be installed on the described pump case, and the thickness of described resin layer is 3mm-5mm.
Compare with existing plastics magnetic drive pump, plastics magnetic drive pump of the present invention in use, because middle body is installed on the ear end face of pump case, the other end of middle body is equipped with suspension, pump shaft can be installed in the chamber of middle body rotationally, the end that pump shaft is positioned at suspension is equipped with coupling, and suspension is fixed on the carriage.Therefore, magnetic drive pump carrying moment when work can act on the middle body, and this can improve the carrying moment of plastics magnetic drive pump of the present invention.Because impeller and pump shaft adopt metallic material to make, its outer surface is coated with fiber-reinforced resin layer, and separation sleeve adopts fiber-reinforced resin to make, and which is provided with the metal strengthening net.Make that related components is anticorrosive, resistance and high temperature resistance property increases substantially, its serviceability temperature can be brought up to 160 ℃, and related components can not occur deforms, because related components can not deform under the High Temperature High Pressure effect, thereby avoided outer coupling and interior coupling bump, the rub separation sleeve that causes, outer coupling and interior coupling to damage, and the plastics magnetic drive pump cisco unity malfunction that causes thus.When damaging appears in component such as separation sleeve, outer coupling and interior coupling, need repairing, when changing, only need pull down middle body and get final product, this feasible maintenance to magnetic drive pump becomes very convenient.So plastics magnetic drive pump of the present invention has anticorrosive, high temperature resistant, long service life, and is easy to maintenance, the big characteristics of carrying moment.
Other details of plastics magnetic drive pump of the present invention and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
