The conveying of hazardous medium.
Background technology
Magnetic drive pump is because using separation sleeve static seal between pump and motor, in can stopping pump chamber, medium leaks outside, extensively
Conveying for danger medium.Magnetic force pump structure is typically by the pump housing, impeller, pump shaft, internal rotor, turn outward
Son, separation sleeve, motor form, and outer rotor is arranged on fixing with the rotating shaft of motor outside separation sleeve connection, interior
Rotor is arranged on fixing with pump shaft inside separation sleeve connection, the pump shaft two sliding axles by internal rotor both ends of the surface
Hold and be arranged in the pump housing.When driven by motor outer rotor rotates, the magnetic force of generation drives internal rotor to rotate, interior turn
Son drives the impeller being fixedly mounted on the pump shaft other end to rotate by pump shaft.The two of existing magnetic drive pump location pump shaft
Individual sliding bearing is separately mounted on the pump housing and separation sleeve, and its major defect is two of installation sliding bearing to be determined
Circle of position lays respectively on two parts, and typically all installs dividing plate between separation sleeve and the pump housing, and therefore zero
Part mismachining tolerance and final assembly error all can cause the error of two sliding bearing concentricitys, and pump shaft will be made to revolve
Increasing the frictional force between sliding bearing when turning, during operation, sliding bearing abrasion is big, noise is high, efficiency is low.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, it is provided that a kind of install pump shaft two
The concentricity of sliding bearing is high, weares and teares little during operation between pump shaft and sliding bearing, and operation noise is low, operation
The novel magnetic Vortex pump that efficiency is high.
The technical solution of the utility model include the pump housing, impeller, pump shaft, internal rotor, outer rotor, separation sleeve,
Motor, link, outer rotor is arranged on fixing with the rotating shaft of motor outside separation sleeve connection, and internal rotor is installed
Fixing with pump shaft inside separation sleeve and be connected, pump shaft is installed on the pump housing by two sliding bearings；Mainly two
Individual sliding bearing is arranged in a bearing body by bearing block respectively, and the radial direction cylindrical convex shoulder of bearing body one end is solid
Dingan County is contained between dividing plate and the pump housing, and internal rotor is fixedly mounted on the pump shaft end of two sliding bearing outer ends.
Preferably, wherein between a sliding bearing end face and internal rotor end face and another sliding bearing
It is respectively mounted thrust ring on pump shaft periphery between end face and pump shaft radially convex shoulder.
Preferably, mounting sleeve between sliding bearing endoporus and pump shaft periphery.
The utility model has the advantages that two sliding bearings of fixing pump shaft are arranged in same bearing body, make
Two sliding bearings supporting pump shaft have higher concentricity, when reducing operation between pump shaft and sliding bearing
Frictional force, the abrasion to sliding bearing is little, reduce run noise, improve operational efficiency.
