Magnetic pump by the pump, magnetic actuator, the motor consists of three parts. The key components of the magnetic actuator consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation cover. When the motor drives the outer magnet rotor to rotate, the magnetic field can penetrate the air gap and the non-magnetic substance to drive the inner magnet rotor connected with the impeller to rotate synchronously to realize the powerless contact transmission and transform the dynamic seal into the static seal. As the pump shaft, the inner rotor is fully closed by the pump body and the isolation sleeve, thus completely solving the problems of running, running, dripping and leakage, and eliminating the leakage of flammable, explosive, toxic and harmful media through the pump seal in the refining and chemical industry Hidden dangers, effectively guarantee the physical and mental health and safety of workers.

The inlaid spiral finned tube is to pre-process the spiral groove of a certain width and depth on the steel pipe, and then inlay the steel strip on the steel pipe on the lathe. During the winding process, due to a certain pre-tightening force, the finned tube steel strip will be tightly clamped in the spiral groove, thus ensuring a certain contact area between the steel strip and the steel tube. In order to prevent the steel strip from springing back and falling off, both ends of the steel strip should be welded to the steel pipe.
In order to facilitate inlaying, there should be a certain side clearance between the steel strip and the spiral groove. If the side clearance is too small and interference is formed, it will be difficult for the mosaic process to proceed smoothly. In addition, the wound steel strip always has a certain springback, as a result, the steel strip and the bottom surface of the spiral groove cannot be well joined. Inlaid fins can be carried out on general-purpose equipment, and the cost is not high, but the process is complicated and the production efficiency is low.
