Swirl-prevention shielding hood of magnetic pump

The utility model provides a swirl-prevention shielding hood of a magnetic pump, which includes a hood body (1), wherein a swirl-prevention cone (2) is arranged on a baffle at the bottom of the hood body (1); at least two spiral diversion trenches (2.1) are arranged on the swirl-prevention cone (2); at least three swirl-reduction grooves (1.1) are arranged on the baffle at the bottom of the hood body (1); the swirl-prevention cone (2) is arranged at the center of the baffle at the bottom of the hood body (1); and the ratio of the outer diameter of the bottom surface of the swirl-prevention cone (2) and the outer diameter of the baffle at the bottom of the hood body 1 is 1/8 to 1/2; and the cone angle of the swirl-prevention cone (2) is 30 DEG to 150 DEG. The swirl-prevention shielding hood of the magnetic pump can effectively decompose swirl force through the diversion trenches when inside medium generates swirling force during the rotation of the magnetic pump, thereby effectively solving the problem that th
