Abstract
A magnetic transmission non-leakage centrifugal fan comprises a motor, a coupler, inner magnetic steel, a shielding case, outer magnetic steel, a middle body, a middle body water jacket, an impeller, a shell, an inner support and an outer support. According to the magnetic transmission non-leakage centrifugal fan, the output shaft of the motor on the centrifugal fan is connected with the outer magnetic steel of a permanent magnet, a main shaft of the impeller is connected with the inner magnetic steel of the permanent magnet, the inner magnetic steel is sealed inside the shielding case, and non-contact transmission of the moment of force is achieved through a push-pull type magnetic structure of the permanent magnet; and due to the fact that the main shaft of the impeller is separated from the output shaft of the motor, the effect that the inside and the outside are isolated and sealed in a static mode can be achieved, the problem of moving sealing of a main shaft of a centrifugal fan in the prior art is solved, thus gas leakage can not happen, and the magnetic transmission non-leakage centrifugal fan is good in safety and wide in range of application. Besides, due to the fact that the shielding case is made of non-metal material, eddy heat which is generated by a traditional shielding case made of metal material through cutting of magnetic lines of force under the action of an alternating magnetic field can be eliminated, working efficiency is promoted, and the magnetic transmission non-leakage centrifugal fan is safe and energy-saving.
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 centrifugal blower.
Background technique
Centrifugal blower is that a kind of mechanical energy that relies on input improves supply gas the side by side machinery of body of gas pressure, is a kind of driven fluid machinery.Centrifugal blower commonly used at present mainly comprises motor and air pump; Wherein air pump is mainly by circular shell be installed in the circular shell and blade-carrying impeller is formed; The output shaft of motor passes the side of 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 enters into the gas access from housing one side the impeller of enclosure interior vertically, utilize the impeller of rotation at a high speed that gas is accelerated, slow down then and change over radially, make kinetic energy convert potential energy (pressure) to, at last the radially gas outlet from the housing along impeller leaves housing, uses for the user.But, there is following point in the centrifugal blower of this prior art: though run through on the output shaft of motor between the position of housing and the 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 centrifugal blower 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 centrifugal blower.
In order to achieve the above object, the magnetic transmission that provides of the utility model does not have the centrifugal blower of leakage and comprises motor, coupling, interior magnet steel, shielding can, outer steel, middle body, middle body water jacket, impeller, housing, inner support and support arm; The left surface middle part of its middle shell is formed with a gas access, and the exterior periphery place is formed with a gas outlet; Impeller is arranged on the inside of housing in the mode of rotating; Middle body water jacket is arranged on the right flank of housing, and the upper end circumferential surface is provided with coolant outlet, and the lower end circumferential surface is provided with the cooling water inlet; Middle body is tabular, is installed on the right flank of middle body water jacket; The main shaft of impeller by bearing run through be arranged in the middle part of body water jacket and middle body, and the main shaft outer end is connected with a tubular inner support, the outer end outer peripheral surface equal intervals of inner support is equipped with multi-disc as the interior magnet steel of internal magnetic field; Be connected with the tubular shielding can that a standoff distance is arranged on the inner support outside on the exterior edge face of middle body; 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 steel of external magnetic field, and interior magnet steel is identical with the coaxial setting of outer steel and axial position.
Described shielding can is the nonmetallic material shielding can.
Joint in described between body and the shielding can is provided with seal ring.
The magnetic transmission that the utility model provides does not have that to leak centrifugal blower be output shaft connection permanent magnet outer steel with motor it on, impeller spindle links to each other with magnet steel in the permanent magnet, and interior magnet steel 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 centrifugal blower 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 centrifugal blower 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.
