Art means, and can being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the high temperature-resistant magnetic pump cooled down according to medium of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
See Fig. 1, this utility model provide a kind of medium cooling high temperature-resistant magnetic pump, including motor 1, motor shaft 2,
Output shaft 9, impeller 8, the pump housing 12, separation sleeve 3, separate cavities 11, sealing gland 10, outer magnet 4 and be arranged concentrically with outer magnet 4
And the inner magnet 5 rotated under the magnetically-actuated of outer magnet 4, also reside in the two ends of motor shaft 2 respectively with outer magnet 4 and motor 1
Being connected, separation sleeve bag 3 overlays on outer magnet 4 and seamless applying with outer magnet 4, the two ends of output shaft 9 respectively with impeller 8 and interior magnetic
Body 5 is connected, and forms separate cavities 11, be provided with close for inner magnet 5 between impeller 8 and inner magnet 5 between inner magnet 5 and separation sleeve 3
The sealing gland 10 being enclosed in the pump housing, arranges cooling sandwith layer in separation sleeve 3.
The high temperature-resistant magnetic pump operation principle of the medium cooling that this utility model provides is as follows:
In the outer circumference of inner magnet and the inner circumferential portion of outer magnet, load onto magnet respectively, interior outer magnet is worked
In the face of neat, i.e. automatic coupling, there is certain air gap between interior outer magnet, be used for isolating actively and slave unit；When magnet is from working as
Front coupling state, when the circumference changing of the relative positions jumps to next couple state, during this skidding, the magnetic field in air gap is rapid
Change, interior outer magnet is simultaneously filled demagnetization by the other side, produces heat, in the short time temperature can rapidly rise to 100 degrees Celsius with
On, thus cause magnet demagnetization, and therefore, between interior outer magnet, a separation sleeve 3 is installed, can be by inner magnet 5 or outer magnetic
Body 4 is closed, and arranges cooling layer in separation sleeve 3, when magnetic drive pump pumped (conveying) medium temperature exceedes regulation, and can be from outside
Cooling is provided, the heat of inner magnet 5 is carried out heat transfer or by air gap, outer magnet 4 carried out heat conduction.
In order to separation sleeve 3 and inner magnet 5 be separated with the medium that magnetic drive pump transmits, sealing gland 10 is set to bearing
Seat, output shaft 9 is set to bearing, and bearing is fixed on bearing block, and one end of bearing block is provided with seal groove, the other end of bearing block
Fix with the pump housing 12 and be connected.
Come in order to the pump head of the magnetic drive pump of conveying medium is completely cut off with inner magnet 5 and separation sleeve 3, prevent pumped (conveying) medium cold
But during, if medium has hard particles, separation sleeve 3 is caused to scratch or scratch；The high temperature-resistant magnetic pump of medium cooling
Also including that hollow pump head 13 and sealing ring, one end of hollow pump head 13 are set to inlet 7, the other end of hollow pump head 13 is arranged
For installing port, the top of hollow pump head 13 is provided with liquid outlet 6, the other end of hollow pump head by the sealing ring in seal groove with
Bearing block seals against, and is bolted on bearing block, and sealing ring is metal o-ring sealing ring.
For the separation sleeve 3 that the resistivity ratio selecting nonferromagnetic is higher, separation sleeve 3 is set to austenitic stainless steel isolation
Set, or titanium alloy separation sleeve, or Hastelloy separation sleeve；So, separation sleeve 3 not only has higher resistivity and also has
Preferably heat conductivility.
In order to ensure that magnetic drive pump runs under the conditions of set point of temperature, prevent medium temperature from exceeding standard, outside Insulation Shell of Magnet Pump
Surface installing platinum resistance temperature sensor, in order to the temperature in detection annular space region, in order to temperature over-range alarm or shutdown.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do
Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
