  Structure acid magnetic pump

  Acid magnetic pump by the pump, impeller, inner magnet and outer magnet, isolation units, pump shafts, pump the outer shaft, bearings, roller bearings, couplings, motors, chassis and other components (Some small acid base magnetic pump, the outer magnet and motor shaft is directly linked together, eliminating the need for external pump shafts, rolling bearings and couplings and other components). Electric barrel pump is a new oil transport equipment, widely used in factories and mines each business unit and suction transport all kinds of oil, such as diesel, kerosene, oil and the like. The pump is compact, stable performance, simple operation, as long as the pump inserted barrels, turn the power switch to suck oil out of the barrel to facilitate saving, high efficiency, this pump is equipped with a single-phase AC motor.

  1, pump body, impeller: seal pump similar.

  2, the magnetic coupling: magnetic coupling by the inner magnet (including a guide ring and sheath), outside the magnet (including a guide ring) and containment shell composition, acid is the core component of the magnetic pump. Reliability structure, magnetic coupling of the magnetic circuit design, the relationship between the parts and materials to the acid magnetic pump, magnetic drive efficiency and service life.

  (1) magnet: the magnet inside the guide ring with an adhesive coupling. To the inner magnet and the dielectric isolation, look for an inner magnet covered with a wrap. There are two kinds of plastic wrap and metal, metal sheath by welding, plastic wrap by injection.

  (2) outside the magnet: outer magnet coupled with the guide ring with an adhesive.

  (3) sets of isolation: isolation units also called glands, located between the inner and outer magnet, the inner and outer magnets are completely separated, the medium enclosed in isolation kit. Containment shell thickness and the operating pressure and temperature related increase in thick, outside the magnet gap size, thus affecting the efficiency of the magnetic drive; too thin impact strength. Isolation and non-metallic sheathed with two metals, metal containment shell eddy current loss, non-metallic containment shell no eddy current losses.

  3, sliding bearing: inner magnetic pump acid pump shaft is supported by sliding bearings. Since the slide bearings are lubricated by the conveying medium to poor lubrication, the sliding bearings should wear and good self-lubricating material. Common bearing material with silicon carbide ceramics, graphite, PTFE and so on.
