As shown in FIG. 1, the corrosion-resistant magnetic pump of the present application is composed of a pump, a magnetic driver and a motor. The key part magnetic driver consists of outer magnetic rotor, inner magnetic rotor and isolating sleeve without magnetic conduction. When the motor drives the outer magnet rotor to rotate, the magnetic field can penetrate through an air gap and nonmagnetic substances to drive the inner magnet rotor connected with the impeller to synchronously rotate, the non-contact transmission of power is realized, the dynamic seal is converted into static seal, the magnetic sealing device comprises a main shaft 1, a plastic layer 2 and an inner magnet 4, one end of the main shaft 1 is provided with the inner magnet 4, the inner magnet 4 drives the main shaft to rotate, one end of the main shaft 1 is uniformly provided with holes 3, the inner magnet 4 is composed of inner magnet steel sheets, and the main shaft 1 and the inner magnet 4 are provided with the plastic layer 2.
The main shaft 1 is made of 45# steel, and is formed by machining a 45# steel blank at one time by a lathe.
The plastic layer 2 is made of fluoroplastic, which has extremely strong corrosion resistance, shows inertia to most chemicals and solvents, can resist strong acid and strong alkali, water and various organic solvents, and has good mechanical toughness.
The plastic layer 2 penetrates through the holes 3 to uniformly wrap the main shaft 1 and the inner magnet 4, the fluoroplastic layer is formed by injection molding after the main shaft 1 and the inner magnet 4 are combined, the integral wrapping effect is achieved, the finish machining is carried out to the required size, and the main shaft 1 and the inner magnet 4 are wrapped by the fluoroplastic through the holes 3 to enhance the firmness of fluoroplastic.
The inner magnet 4 is provided with 6-10 blocks of inner magnetic steel sheets which are uniformly arranged at the outer ring of one section of the main shaft 1, so that the normal rotation of the main shaft 1 is ensured.
The utility model provides a thinking and implementation method of corrosion-resistant magnetic drive pump, the concrete application way is many, only above is the utility model discloses an optimal implementation mode should point out, to the ordinary technical personnel of this technical field, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements should also be regarded as the utility model discloses a protection scope.
