Abstract
The invention discloses an axial balanced type metal magnetic drive pump. The axial balanced type metal magnetic drive pump comprises a chassis, and is characterized in that a pump body and a motor are fixedly mounted on the chassis, an open cavity is formed in the right end surface of the pump body, an impeller is rotatably mounted in the cavity, an opening part of the cavity is connected with a pump cover, a limiting projection is arranged on the right end surface of the impeller, a sealing shoulder which is matched with the limiting projection is arranged on the inner wall of the pump cover, the left end of the pump cover is in the shape of a conical horn mouth, a cylindrical structure is arranged at the right end of the pump cover, and a through hole is formed in a side wall of the pump cover. The axial balanced type metal magnetic drive pump is simple in structure, pressure in the pump body is balanced, air bubbles are not generated easily, airtightness is good, and a rotating shaft cannot loosen easily.
Description
Technical field
The present invention relates to a kind of magnetic drive pump, specifically a kind of longitudinal balance formula metal magnetic pump.
Background technique
High-temperature Magnetic Pump is the modern magnetomechanics principle of application, the magnetic drives of permanent magnet is utilized to realize a kind of new pump of the non contact transmission of moment of torsion, when being exactly the rotation of driven by motor external rotor (i.e. outer steel) assembly, internal rotor (namely magnet steel) assembly and impeller synchronous rotary is driven through separation sleeve by the effect magnetic line of force in magnetic field, because medium is enclosed in static separation sleeve, thus reach the object that No leakage pumps medium.The pump housing, pump cover devise double-deck cooling (insulation) device, water, nitrogen (steam) can be used pump in-vivo medium cooling (insulation), guarantee that the medium entered in pump remains on safe handling at better suited temperature, ensure that medium in course of conveying can not condensation, crystallization, vaporization, thoroughly solve the shaft sealing leakage of mechanical pump, condensation, crystallization, vaporization, and hermetically sealed, the No leakage of design, pollution-free, high temperature resistant, insulation, energy-efficient infant industry pump.
