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, relate in particular to a kind of separation sleeve assembly of magnetic drive pump.
Background technique
Magnetic drive pump is conventional fluid conveying machine, with it, without leakage, low noise, the advantage such as stable, is widely used in the industries such as medicine, chemical industry, bathroom.Separation sleeve is the vital part in magnetic drive pump, and interior magnet rotor and outer magnet rotor are kept apart, and fed sheet of a media is sealed in the pump housing, realizes completely without revealing.What existing separation sleeve was common is plain base, and it is comprised of flange, thin-walled cylinder and base plate.When at conveying easily-crystallized medium; shutdown can cause housing, pump cover, the not emptying easy crystal medium in interior magnet rotor place to become powdery, bulk; again start; resistance is large; can cause bearing damage; even cannot start; this just need to become powdery by solidifying, block easy crystal medium melts; the easy crystal medium at housing and pump cover place easily melts; but the easy crystal medium at interior magnet rotor place, because reasons in structure thermal source cannot reach this region, starts again, and resistance is large; can cause bearing damage, even cannot start.The separation sleeve assembly that also there is no at present such magnetic drive pump, it can make to shut down the easy crystal medium region that rear thermal source reaches interior magnet rotor place, reduces the magnetic drive pump resistance of start again, extends the working life of magnetic drive pump.
Summary of the invention
Technical problem to be solved by this invention is: the separation sleeve assembly that a kind of magnetic drive pump is provided; the use of the separation sleeve assembly of this kind of magnetic drive pump can make to shut down the easy crystal medium region that rear thermal source reaches interior magnet rotor place; thereby reduce the magnetic drive pump resistance of start again, extend the working life of magnetic drive pump.
Solve this technical problem, technological scheme of the present invention is: a kind of separation sleeve assembly of magnetic drive pump, it comprises interior separation sleeve, outer separation sleeve, electrothermal mechanism, circular heat-conducting plate and lining ring, described interior separation sleeve is by interior separation sleeve flange, interior separation sleeve thin-walled cylinder and interior separation sleeve base plate form, described outer separation sleeve is by outer separation sleeve flange, outer separation sleeve thin-walled cylinder and outer separation sleeve base plate form, described lining ring is between interior separation sleeve flange and outer separation sleeve flange, described interior separation sleeve, between outer separation sleeve and lining ring, form the cavity of sealing, described circular heat-conducting plate is arranged at the middle part of interior separation sleeve base plate, described circular heat-conducting plate and electrothermal mechanism conducting.
Described electrothermal mechanism is provided with heat protector.
On described lining ring, be provided with alarm.
The separation sleeve assembly of a kind of magnetic drive pump of the present invention adopts such structure; can make to shut down the easy crystal medium region that rear thermal source reaches interior magnet rotor place; thereby reduce the magnetic drive pump resistance of start again; extend the working life of magnetic drive pump; and can find in time the damage of separation sleeve, can avoid the generation of leakage accident.

Fig. 2 is that the separation sleeve assembly of a kind of magnetic drive pump of the present invention shown in Fig. 1 is used status architecture schematic diagram;
In Fig. 1, Fig. 2,1, housing; 2, impeller; 3, pump cover; 4, electrothermal mechanism; 5, interior separation sleeve; 6, outer separation sleeve; 7, support; 8, motor; 9, outer magnet rotor; 10, interior magnet rotor; 11, base; 12, pump shaft; 13, alarm; 14, circular heat-conducting plate; 15, lining ring.
Embodiment
As shown in Figure 1 and Figure 2, magnetic drive pump comprises housing 1, impeller 2, pump cover 3, support 7, base 11, pump shaft 12, interior magnet rotor 10, outer magnet rotor 9 and motor 8, impeller 2 is positioned at one end of pump shaft 12, interior magnet rotor 10 is positioned at the other end of pump shaft 12, outer magnet rotor 9 is connected with motor output shaft, between outer magnet rotor 9 and interior magnet rotor 10, has separation sleeve assembly.
Separation sleeve assembly comprises interior separation sleeve 5, outer separation sleeve 6, electrothermal mechanism 4, circular heat-conducting plate 14 and lining ring 15, interior separation sleeve 5 is by interior separation sleeve flange, interior separation sleeve thin-walled cylinder and interior separation sleeve base plate form, outer separation sleeve 6 is by outer separation sleeve flange, outer separation sleeve thin-walled cylinder and outer separation sleeve base plate form, lining ring 15 is between interior separation sleeve flange and outer separation sleeve flange, interior separation sleeve 5, between outer separation sleeve 6 and lining ring 15, form the cavity of sealing, circular heat-conducting plate 14 is placed in the middle part of interior separation sleeve base plate, circular heat-conducting plate 14 and electrothermal mechanism 4 conductings, electrothermal mechanism 4 is placed in pump cover 3 tops.
Such structure; before again starting after shutdown; first by electrothermal mechanism 4 and power turn-on; circular heat-conducting plate 14 heatings at interior separation sleeve base plate middle part; in having solved for a long time, the easy crystal medium thermal source at magnet rotor place cannot reach the problem in this region; can shut down at any time and start, increase the service life, reduce customer using cost.
In order to prevent interior magnet rotor, the demagnetization of outer magnet rotor excess Temperature, on electrothermal mechanism 4, be provided with heat protector, magnetic drive pump, when conveying easily-crystallized medium, just can suitably be opened electrothermal mechanism in cold season when magnetic drive pump moves like this.
When magnetic drive pump is after operation a period of time, when the medium of carrying contains the solid particles such as catalyzer, likely that interior separation sleeve is worn out, on lining ring, be provided with alarm, just can find in time the damage of separation sleeve, can avoid the generation of leakage accident.
