Shielding pump impeller balance hole enlargement, what is the change in force on the impeller
Connect together: pump and motorThe same shaft: the rotor of the motor and the impeller of the pumpShielding sleeve: separate the rotor and stator of the motor
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic fieldIn addition, the manufacture of canned pumps is not complicated, and the hydraulic end can be designed and manufactured in accordance with the structural type and relevant standards and specifications commonly adopted by centrifugal pumps.
