Abstract To investigate the relationship between cooling circulation loop of cannedpumps and the internal temperature rising, the distribution of temperature field and pressure field in the canned motor and the temperature rise in the cooling circulation loop were simulated and the convective heat transfer information between the coolant and the rotor was analyzed.The thermal-fluid coupling numerical analysis of the whole flow field of the impeller, the chamber and the cooling circulation circuit of the canned pump was carried out by using the engineering simulation software CFD based on the real prototype of the stampingwelding cannedmotor pump. The results show that under different working conditions, the temperature rise in the shielding gap is very small, the maximum temperature difference is only 0.97 ℃. Under the design condition, the different shaft aperture has little effect on the temperature rise of the cannedmotor. With the increase of axial aperture, the maximum temperature of cannedmotor is decreasing. Under the design condition, the relationship between cooling cycle flow and axial aperture is compared with the numerical calculation and theoretical calculation.It is concluded that the results of numerical calculation and theoretical calculation are basically the same, which provides a theoretical basis for the design of cooling cycle circuit of cannedpump.
