Description
Technical field
The utility model relates to pump, relates in particular to a kind of magnetic driver of magnetic drive pump.
Background technique
Magnetic drive pump is by pump, magnetic driver and motor three parts form, pump comprises housing, impeller, pump cover and pump shaft, magnetic driver comprises outer magnet rotor, interior magnet rotor and separation sleeve, motor and outer magnet rotor are linked togather composition driver part, impeller and interior magnet rotor are linked togather composition driven member, between interior female rotor and outer magnet rotor, there is seal isolation cover, interior magnet rotor is among medium, magnet rotor in motor rotates and makes a concerted effort to drive by the magnetic pole of outer magnet rotor and the suction of the magnetic pole of interior magnet rotor coupling generation and the push-and-pull of repulsion composition, pump shaft and impeller synchronously rotate, separation sleeve belongs to the small pressure container that has liquid rotation in cover.Magnetic drive pump, when conveying easily-crystallized medium, should drain raffinate in pump in time with clear water cleaning after use, can cause environmental pollution.And exist raffinate in pump to arrange phenomenon not to the utmost.When shutting down; not emptying easy crystal medium solidifies; again start; resistance is large; can cause bearing damage; even cannot start, this just need to melt the easy crystal medium that solidifies, and the easy crystal medium at interior magnet rotor place can not request stop when at conveying easily-crystallized medium because making thermal source reach that this region causes.The magnetic driver that also there is no at present such magnetic drive pump, its use can make magnetic drive pump shut down at any time and start, and extends magnetic drive pump working life, reduces customer using cost.
Model utility content
Technical problem to be solved in the utility model is: the magnetic driver that a kind of magnetic drive pump is provided; the use of the magnetic driver of this kind of magnetic drive pump can make magnetic drive pump when conveying easily-crystallized medium, shut down at any time and start; extend magnetic drive pump working life, reduce customer using cost.
Solve this technical problem, the technical solution of the utility model is: a kind of magnetic driver of magnetic drive pump, magnetic drive pump comprises magnetic driver, housing, impeller, pump cover, pump shaft, motor and the liner plate that is positioned at motor end, magnetic driver comprises outer magnet rotor, interior magnet rotor and separation sleeve, described separation sleeve is by flange, thin-walled cylinder and base plate form, described interior magnet rotor and motor shaft are affixed, described outer magnet rotor and pump shaft are affixed, the flange of described separation sleeve is connected with liner plate, the thin-walled cylinder of described separation sleeve and base plate are between interior magnet rotor and outer magnet rotor.
The bottom of described liner plate is provided with is convenient to loose warm bar-shaped trough.
The magnetic driver of a kind of magnetic drive pump of the utility model adopts such structure, compared with prior art, changed the position of interior magnet rotor and outer magnet rotor, interior magnet rotor and motor shaft is affixed, outer magnet rotor and pump shaft are affixed, and have changed the direction of separation sleeve, and in driven by motor, magnet rotor rotates, drive outer magnet rotor to rotate, outer magnet rotor is driven member again.Change so original separation sleeve and belonged to the situation that has liquid small pressure container of rotation in cover; make liquid outside cover; solved in magnet rotor place easy crystal medium because of cannot make thermal source reach this region cause when the conveying easily-crystallized medium can not request stop problem; make magnetic drive pump can shut down at any time and start when conveying easily-crystallized medium; extend magnetic drive pump working life, reduce customer using cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the magnetic driver of a kind of magnetic drive pump of the utility model is described in further detail;
Fig. 1 is the use status architecture schematic diagram of the magnetic driver of a kind of magnetic drive pump of the utility model;
Fig. 2 is the heat-insulation support shown in Fig. 1 and pump cover linkage structure schematic diagram;
In Fig. 1, Fig. 2,1, housing; 2, impeller; 3, pump cover; 4, pump shaft; 5, heat-insulation support; 6, steam ingress pipe; 7, outer magnet rotor; 8, liner plate; 9, interior magnet rotor; 10, motor shaft; 11, separation sleeve; 12, steam delivery line; 13, base; 14, toroidal cavity; 15, through hole; 17, support end plate; 18, cylindrical cavity; 19, inner ring; 20, outer ring.
Embodiment
As shown in Figure 1 and Figure 2, magnetic drive pump comprise housing 1, impeller 2, pump cover 3, pump shaft 4, heat-insulation support 5, steam ingress pipe 6, liner plate 8,, motor shaft 10, steam delivery line 12, base 13 and magnetic driver, magnetic driver comprises outer magnet rotor 7, interior magnet rotor 9 and separation sleeve 11, separation sleeve 11 is comprised of flange, thin-walled cylinder and base plate, outer magnet rotor 7 is affixed with pump shaft 4, interior magnet rotor 9 is affixed with motor shaft 10, the flange of separation sleeve 11 is connected with liner plate 8, and the thin-walled cylinder of separation sleeve 11 and base plate are between interior magnet rotor 9 and outer magnet rotor 7.Between pump cover 3 and liner plate 8, there is heat-insulation support 5, heat-insulation support 5 comprises outer ring 20, inner ring 19 and support end plate 17, support end plate 17 joins with liner plate 8, outer ring 20 has respectively steam ingress pipe 6 and steam delivery line 12 near the upper and lower of support end plate, and steam ingress pipe 6 and steam delivery line 12 removably connect with the outer ring 20 of heat-insulation support 5 respectively.Between circle 20 and inner ring 19, form the toroidal cavity 14 of sealing, a side sentence near pump cover 3 on inner ring 19 has the through hole 15 of being convenient to steam turnover pump cover cavity, between pump cover 3 and support end plate 17, form cylindrical cavity 18, outer magnet rotor 7, interior magnet rotor 9 and isolation 11 covers are positioned at this cylindrical cavity 1, and the bottom of liner plate 8 has is convenient to loose warm bar-shaped trough.
Such structure, compared with prior art, has changed the position of interior magnet rotor and outer magnet rotor, interior magnet rotor and motor shaft is affixed, and outer magnet rotor and pump shaft are affixed, and have changed the direction of separation sleeve, in driven by motor, magnet rotor rotates, then drives outer magnet rotor to rotate, and outer magnet rotor is driven member.Designed heat-insulation support, increased heating mechanism, heating mechanism is input into steam from steam ingress pipe, and steam enters in the toroidal cavity of heat-insulation support, and steam enters pump cover cavity from the through hole of heat-insulation support inner ring simultaneously.Although steam cannot enter the cylindrical cavity with outer magnet rotor like this, by the heat conduction of heat-insulation support inner ring, the solid sulphur having in cylindrical cavity is melted.Solved in magnet rotor place easy crystal medium because of cannot make thermal source reach this region cause when the conveying easily-crystallized medium can not request stop problem; make magnetic drive pump can shut down at any time and start when conveying easily-crystallized medium; extend magnetic drive pump working life, reduce customer using cost.
