Description
Technical field
The utility model belongs to source of the gas generation equipment technical field, and particularly relating to a kind of magnetic transmission does not have the leakage Cyclone wind motor.
Background technique
Cyclone wind motor is a kind of in the high pressure positive blower, also claims ring-shape blower fan, has that pressure height, air quantity are big, a low noise, characteristics such as high temperature resistant, and Cyclone wind motor commonly used at present mainly comprises motor and vortex pump; Wherein vortex pump is mainly by the annular pump housing be installed in the annular pump housing and the impeller that has tens of blades is formed; The output shaft of motor passes the side of the pump housing and directly links to each other with the main shaft of impeller.When motor rotates, impeller is rotation at a high speed also, meanwhile, extraneous gas will enter between the blade of pump housing inside from the suction port on the pump housing one side, because action of centrifugal force, the air between two blades will be rapidly to the motion of impeller outer edge direction, and enters in the toroidal cavity of the pump housing at this place, return impeller again then and be accelerated again, circulate in the same way from the starting point of blade again more afterwards.Because blast is superposeed fast, has just formed high pressure or high suction thus.The circulating air flow that last impeller rotation produces will leave vortex pump along the axial air outlet from the pump housing of impeller with high energy, use for the user.But, there is following point in the Cyclone wind motor of this prior art: though run through on the output shaft of motor between the position of the pump housing and the pump housing seal arrangement is installed, but, lengthening along with service time, wearing and tearing can appear in seal arrangement undoubtedly, at this moment will form the slit at this position, cause that thus gas leaks, so not only can influence the purity of pressurized gas, and the operating cost height.In addition, if pressurized gas is inflammable and explosive or poisonous, harmful gas, in case occur to leak just might cause environmental pollution, badly damaged operator are healthy or safety issue such as detonation, so make the Cyclone wind motor using scope of this structure be restricted.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of applied widely, safe and reliable magnetic transmission not have the leakage Cyclone wind motor.
In order to achieve the above object, the magnetic transmission that provides of the utility model does not have the Cyclone wind motor of leakage and comprises motor, coupling, interior magnetic cylinder, outer magnetic cylinder, shielding can, middle body, housing, impeller, seal closure, inner support and support arm; Wherein middle part, a side of seal closure is formed with a seal closure suction port, and the another side is opening-like; Middle body is tabular, covers the lateral opening place of seal closure; Housing is installed in the inside of seal closure, and its lateral edge is formed with a shell air inlet, is connected with an outlet pipe near the lateral edge position of middle body, and the other end of outlet pipe extends to the outside behind the body in running through; Impeller is arranged on the inside of housing in the mode of rotating, the middle part of body during its main shaft middle part is installed in by bearing, and the main shaft outer end is connected with a tubular inner support, and the outer end outer peripheral surface equal intervals of inner support is equipped with multi-disc as the interior magnetic cylinder of internal magnetic field; The middle part, exterior edge face of middle body is connected with the tubular shielding can that a standoff distance is arranged on the inner support outside; The output shaft of motor is connected with the tubular support arm that a standoff distance is arranged on the shielding can outside through coupling, the outer end inner peripheral surface equal intervals of support arm is equipped with multi-disc as the outer magnetic cylinder of external magnetic field, and interior magnetic cylinder is identical with the coaxial setting of outer magnetic cylinder and axial position.
Described shielding can is the nonmetallic material shielding can.
Joint in described between body and seal closure, middle body and the shielding can is provided with seal ring.
It is with magnetic cylinder outside the output shaft connection permanent magnet of motor on it that the magnetic transmission that the utility model provides does not have the leakage Cyclone wind motor, impeller spindle links to each other with magnetic cylinder in the permanent magnet, and interior magnetic cylinder is enclosed in the inside of shielding can, utilize the non contact transmission of the plug-type magnetic structure realization moment of permanent magnet, because the output shaft of impeller spindle and motor is separated, therefore can reach the inner and extraneous static airtight effect of isolating, solved prior art vortex pump main shaft motive sealing problem, so gas can not occur leaks, Security is good, applied range.In addition, because shielding can adopts nonmetallic material to make, therefore can eliminate traditional metallic material shielding can eddy current heat that cutting magnetic line produces under action of alternating magnetic field, improve working efficiency and energy-saving safe.In addition, this Cyclone wind motor also has compact structure, volume is little, noise is low, little, the easy care maintenance of vibrations, long service life, low cost and other advantages.
Description of drawings
