Development of vehicle-mounted compact magnetic pump
In order to meet the needs of supporting pumps for vehicle-mounted mobile equipment,a vehicle-mounted compact magnetic pump with low flow,high head,small size and no leakage was developed.According to the technical parameters of the vehicle-mounted compact magnetic pump,key design technologies such as hydraulic design,magnetic coupling design and pump unit structural design were introduced in detail.By integrating impeller,inner magnetic block,guide bearing,and rear and front thrust bearings,the inner magnetic rotor body of the impeller was formed,which has the comprehensive functions of radial support,axial positioning,and axial force self-balancing at the same time.The wall thickness,radial deformation and magnetic eddy current loss of the isolation sleeve were calculated and analyzed.The results show that the radial displacement of the isolation sleeve is 0.03 mm,and the magnetic eddy current loss accounts for 5%of the supporting power,which meets the relevant technical requirements.Meanwhile,the prototype was evaluated through performance tests and the results meet the design requirements.The research can provide some references for the design of related special purpose magnetic pumps.
