Abstract
The invention discloses an isolation cover assembly of a magnetic force pump. The isolation cover assembly comprises an internal isolation cover, an external isolation cover, an electric heating mechanism, a circular heat conducting strip and a lining ring, wherein the internal isolation cover consists of an internal isolation cover flange, an internal isolation cover thin-wall barrel and an internal isolation cover bottom plate; the external isolation cover consists of an external isolation cover flange, an external isolation cover thin-wall barrel and an external isolation cover bottom plate; the lining ring is located between the internal isolation cover and the external isolation cover; a sealed cavity is formed among the internal isolation cover, the external isolation cover and the lining ring; the circular heat conducting strip is arranged in the middle part of the internal isolation cover bottom plate; the circular heat conducting strip is connected with the electric heating mechanism. As the isolation cover assembly of the magnetic force pump provided by the invention adopts such a structure, a heat source can reach an easy-to-crystallize medium area at an internal magnetic rotor after shut-down; therefore the restart resistance of the magnetic force pump is decreased; the service life of the magnetic force pump is prolonged; moreover, the damage of the isolation cover can be discovered in time, so that a leakage accident is avoided.
Description
Technical field
The present invention relates to pump, the separation sleeve assembly of more particularly, to a kind of magnetic drive pump.
Background technology
Magnetic drive pump is conventional fluid conveying machine, no revealed with it, low noise, stable the advantages of, by extensively should
For industries such as medicine, chemical industry, bathrooms.Separation sleeve is the vital part in magnetic drive pump, by interior magnet rotor and outer magnet rotor every
Leave, pumped (conveying) medium is sealed in the pump housing, realize entirely without leakage.Existing separation sleeve common for plain base, its by
Flange, thin wall cylinder and base plate composition.When in conveying easily-crystallized medium, shutdown can lead to not arrange at housing, pump cover, interior magnet rotor
Empty easy crystal medium becomes powdering, bulk, is again started up, and resistance is big, can lead to bearing damage, or even cannot start, this is just
Need for solidification to become powdering, the thawing of block easy crystal medium, the easy crystal medium at housing and pump cover easily melts, but interior
Easy crystal medium at magnet rotor is unable to reach this region due to reasons in structure thermal source, is again started up, and resistance is big, can lead to bearing
Damage, or even cannot start.There is presently no the separation sleeve assembly of such magnetic drive pump, after it can make shutdown, thermal source reaches interior magnetic
Easy crystal medium region at rotor, reduces magnetic drive pump and is again started up resistance, extend the service life of magnetic drive pump.
Content of the invention
The technical problem to be solved is: provide a kind of magnetic drive pump separation sleeve assembly, this kind of magnetic drive pump every
From set assembly using thermal source after shutdown can be made to reach the easy crystal medium region away from interior magnet rotor, thus reducing magnetic drive pump again
The resistance of start, extends the service life of magnetic drive pump.
Solve this technical problem, the technical scheme is that a kind of separation sleeve assembly of magnetic drive pump, it include in every
From set, outer separation sleeve, electrothermal mechanism, circular conducting strip and lining ring, described interior separation sleeve is by interior separation sleeve flange, interior separation sleeve
Thin wall cylinder and interior separation sleeve base plate composition, described outer separation sleeve is by outer separation sleeve flange, outer separation sleeve thin wall cylinder and outer isolation
Set base plate composition, described lining ring is located between interior separation sleeve flange and outer separation sleeve flange, described interior separation sleeve, outer isolation
Form the cavity of closing, described circular conducting strip is arranged at the middle part of interior separation sleeve base plate, described circle between set and lining ring
Shape conducting strip is turned on electrothermal mechanism.
Described electrothermal mechanism is provided with thermal protector.
It is provided with alarm on described lining ring.
A kind of separation sleeve assembly of magnetic drive pump of the present invention adopts such structure, and after making shutdown, thermal source reaches interior magnet rotor
The easy crystal medium region at place, thus reducing magnetic drive pump to be again started up resistance, extends the service life of magnetic drive pump, and can be timely
Find the damage of separation sleeve, be avoided that the generation of leakage accident.

Specific embodiment
As shown in Figure 1 and Figure 2, magnetic drive pump includes housing 1, impeller 2, pump cover 3, support 7, base 11, pump shaft 12, interior magnetic turn
Son 10, outer magnet rotor 9 and motor 8, impeller 2 is located at one end of pump shaft 12, and interior magnet rotor 10 is located at the other end of pump shaft 12, outward
Magnet rotor 9 is connected with motor output shaft, has separation sleeve assembly between outer magnet rotor 9 and interior magnet rotor 10.
Separation sleeve assembly includes interior separation sleeve 5, outer separation sleeve 6, electrothermal mechanism 4, circular conducting strip 14 and lining ring 15, interior every
5 be made up of interior separation sleeve flange, interior separation sleeve thin wall cylinder and interior separation sleeve base plate from set, outer separation sleeve 6 by outer separation sleeve flange,
Outer separation sleeve thin wall cylinder and outer separation sleeve base plate composition, lining ring 15 is located between interior separation sleeve flange and outer separation sleeve flange, interior
Form the cavity of closing, circular conducting strip 14 is placed in interior separation sleeve base plate between separation sleeve 5, outer separation sleeve 6 and lining ring 15
Portion, circular conducting strip 14 and electrothermal mechanism 4 turn on, and electrothermal mechanism 4 is placed in above pump cover 3.
Such structure, before being again started up after shutdown, first by electrothermal mechanism 4 and power supply conducting, in the middle part of interior separation sleeve base plate
Circular conducting strip 14 generate heat, solve the easy crystal medium thermal source at interior magnet rotor for a long time and be unable to reach asking of this region
Topic, can shut down at any time and start, increase the service life, and reduce customer using cost.
In order to prevent interior magnet rotor, the too high demagnetization of outer magnet rotor temperature, electrothermal mechanism 4 is provided with thermal protector, this
Sample magnetic drive pump, in conveying easily-crystallized medium, just can suitably open electrothermal mechanism in magnetic force pump operation in cold season.
When magnetic force pump operation for a period of time after, when the medium of conveying is contained within the solid particles such as catalyst it is possible to will be interior
Separation sleeve is worn out, is provided with alarm it is possible to find the damage of separation sleeve in time on lining ring, is avoided that sending out of leakage accident
