Description
Technical field
The present invention relates to pump, relate in particular to a kind of crystallization-preventive magnetic drive pump.
Background technique
Magnetic drive pump is conventional fluid conveying machine,, is widely used in the industries such as medicine, chemical industry, bathroom without leakage, low noise, the advantage such as stable with it.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 made up 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 is because reasons in structure thermal source cannot reach this region; cause being difficult to shutting down at any time and starting, make troubles to user, increased customer using cost.
Summary of the invention
Technical problem to be solved by this invention is: a kind of crystallization-preventive magnetic drive pump is provided, and this kind of crystallization-preventive magnetic drive pump can be shut down at any time and start, and increases the service life, and reduces customer using cost.
Solve this technical problem, technological scheme of the present invention is: a kind of crystallization-preventive magnetic drive pump, comprises housing, impeller, pump cover, pump shaft, interior magnet rotor, outer magnet rotor and motor, described impeller is positioned at one end of pump shaft, described interior magnet rotor is positioned at the other end of pump shaft, described outer magnet rotor is connected with motor output shaft, between described outer magnet rotor and interior magnet rotor, be provided with separation sleeve assembly, described separation sleeve assembly 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 composition, described outer separation sleeve is by outer separation sleeve flange, outer separation sleeve thin-walled cylinder and outer separation sleeve base plate composition, described lining ring between interior separation sleeve flange and outer separation sleeve flange, described interior separation sleeve, the cavity that forms sealing between outer separation sleeve and lining ring, 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 placed in pump cover top.
Described electrothermal mechanism is provided with heat protector.
On described lining ring, be provided with alarm.
A kind of crystallization-preventive magnetic drive pump of the present invention adopts such structure; compared with prior art; adopt two separation sleeves and electrothermal mechanism; before again starting after shutdown, first by electrothermal mechanism and power turn-on, the circular heat-conducting plate heating 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.A kind of crystallization-preventive magnetic drive pump of the present invention simultaneously can be found the damage of separation sleeve in time, avoids the generation of leakage accident.
