Abstract

The invention discloses a novel mechanical sealing part of a magnetic suspension energy-saving air blower. The mechanical sealing part comprises a shaft sleeve, a first sealing ring, a second sealing ring, a buffer block, a flow guide ring, a magnetic controller, a dynamic ring and a static ring, and is characterized in that a retainer ring, a positioning ring, a fixing ring, a limiting ring, a fastening ring and a seal ring are arranged on the shaft sleeve, and the seal ring is arranged between the shaft sleeve and the positioning ring; the first sealing ring is provided with a guide-in groove; one end of the second sealing ring is connected with the shaft sleeve; the second sealing ring is connected with the first sealing ring through a connected screw and is provided with a guide-out groove; the dynamic ring is arranged on the magnetic controller; and the static ring is connected with the dynamic ring and is connected with the positioning ring through springs. The magnetic controller can adjust the magnetism obtaining amount of the mechanical sealing part according to the pressure of the air blower, the rotating speed of the air blower and the input amount of static electricity, so that the magnetic mechanical sealing part reaches a frictionless state, and the leak-tightness sealing effect is ensured.

Description

technical field [0001] The invention relates to a seal, in particular to a mechanical seal for a magnetic levitation energy-saving blower. Background technique [0002] The magnetic levitation energy-saving blower is one of the most important process equipment used in the sewage treatment system of nitrogen high-pressure chemical enterprises. The performance of its seals directly affects the working quality of the magnetic levitation energy-saving blower. Poor effect and short service life are gradually eliminated. For example, the patent application number 201520283407.X discloses a magnetic levitation sealing device in a magnetic levitation high-speed blower, which solves the problem of scraping between the rotor and the labyrinth seal stator during the working process, but it has the magnetization of the mechanical seal The volume cannot be adjusted according to the pressure of the fan, the speed of the fan and the input of static electricity, the energy saving is not hi...
