Description
Technical field
The utility model relates to a kind of pump of carrying liquid, is specifically related to a kind of magnetic force driving pump of carrying inflammable, explosive, poisonous, harmful liquid.
Background technique
The pump shaft two ends of traditional magnetic drive pump generally all are fixed on the pump housing and the separation sleeve, and because magnetic force transmitting torque reason, separation sleeve generally all is designed to thin-walled as much as possible, separation sleeve easy deformation even produce to scrape with outer steel and put on the skin and rupture and leakage when pump turns round for a long time like this; Screw threads for fastening is all adopted at the pump shaft two ends; It is inner even also have air to irritate behind the liquid separation sleeve before the circulating lubrication hole simplicity of design, pump running, thereby causes this pump to do the running phenomenon, during the maintenance pump in some separation sleeve even also have the partial corrosion medium; Bearing housing generally adopts carbon graphite material, and pump shaft is direct and bearing housing friction work; Dynamic and static ring adopts carbon graphite and stupalith, and these materials all wear and tear cracked easily; And all be designed to the individual layer separation sleeve, thus when bad working environments turns round after the separation sleeve deformation fracture dielectric leakage accidents caused.
The model utility content
The object of the invention is to provide a kind of production and processing to be easy to realize, can guarantee the magnetic force driving pump of safe handling when bad working environments.
The technical solution of the utility model is: a kind of magnetic force driving pump, comprise the pump housing, impeller, pump cover, pump shaft, bearing housing, axle sleeve, interior magnet rotor, interior separation sleeve, outer separation sleeve, outer magnet rotor, outer magnet rotor and interior magnet rotor are provided with some to magnet, separation sleeve is located between outer magnet rotor and the interior magnet rotor, it is characterized in that: pump cover can particular design become cavity and adopt double-deck separation sleeve design, impeller, the weight of pump shaft and interior magnet rotor is born by pump cover, axle sleeve is by the pin transmitting torque that is fixed on impeller and the interior magnet rotor, pump shaft one end adopts big shaft shoulder structure, sliding bearing pair adopts novel pressureless sintering carbofrax material, pump cover is provided with lubricated and discharge orifice, double-deck separation sleeve design.
The medium that carry when pump (1) the utlity model has following advantage: when need heat or cool off, pump cover can particular design become cavity and adopt double-deck separation sleeve design, utilize outside hot body/cold body, be directly conducted to pump chamber, sliding bearing pair, separation sleeve inner chamber and come heating or cooling medium; (2) weight of impeller, pump shaft and interior magnet rotor is born by pump cover; (3) two axle sleeves on the pump shaft guarantee axle sleeve and pump shaft run-in synchronism by the pin transmitting torque that is fixed on impeller and the interior magnet rotor; (4) pump shaft one end adopts big shaft shoulder structure to locate interior magnet rotor, and the easier assurance precision of pump shaft size is assembled convenient like this; (5) sliding bearing pair adopts novel pressureless sintering carbofrax material, and bearing housing inside is provided with several lubrication grooves, has characteristics such as high hardness, high abrasion; (6) interior circulating fluid is used to take away heat and the lubrication sliding bearing that is produced by eddy current on the separation sleeve, and reasonable structural design makes all inner loop systems all have enough pressure and flow to guarantee pump stable operation; (7) separation sleeve has and drains medium when repairing (termination of pumping) and emptying automatically when perfusion (before starting) ability fully, generally makes with high-quality stainless steel employing advanced technologies; (8) design of double-deck separation sleeve also can by the leak case of control system monitoring one-level separation sleeve, guarantee that magnetic drive pump also can normally move in more severe occasion at the secondary separation sleeve piecing devices sensor that leaks hunting.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Magnetic drive pump comprises the pump housing 1, impeller 2, pump cover 3, pump shaft 4, bearing housing 5, axle sleeve 6, interior magnet rotor 7, interior separation sleeve 8, outer separation sleeve 9, outer magnet rotor 10 as shown in Figure 1.Motor shaft is fixedlyed connected with outer magnet rotor 10 bottom center, fixedly connected with pump shaft 4 in one cylindrical interior magnet rotor 7 centers, interior magnet rotor is dissolved in the outer magnet rotor, and with outer magnet rotor arranged concentric, establish separation sleeve 8 and 9 between interior magnet rotor and the outer magnet rotor, separation sleeve and pump cover 3 are tightly connected, and pump cover 3 is tightly connected with the pump housing 1 again.
During work, the outer magnet rotor 10 of driven by motor rotates, because the magnetic pull effect, interior magnet rotor 7 is driven, because it is connected wheel rotation with pump shaft 4.And the pump shaft afterbody is processed with a big shaft shoulder, and interior magnet rotor directly locate by pump cover 3, bearing housing 5 and axle sleeve 6, can be as old-fashioned magnetic drive pump with magnet rotor in the nut check, during assembling in magnet rotor rigging position can with some discrepancy of position that designs.Axle sleeve 6 on the pump shaft connects transmitting torque by pin with impeller 2 and interior magnet rotor 7, thereby pump shaft 4 just can not skid in axle sleeve 6 holes, rotates pump working synchronously with axle sleeve.And set up straight hole up and down on the pump cover 3, the discharging of separation sleeve 8 interior media or air also has an inclined hole in being convenient on the pump cover, and the pressure forced medium chain-oiled bearing that produces during by pump work cover 5 and axle sleeve 6 guarantee the pump safe handling.When the medium of carrying when pump need heat or cool off, pump cover can particular design become cavity and adopt the design of double-deck separation sleeve, utilizes outside hot body/cold body, was directly conducted to pump chamber, sliding bearing pair, separation sleeve inner chamber and came heating or cooling medium.And the design of double-deck separation sleeve also can by the leak case of control system monitoring one-level separation sleeve, guarantee that magnetic drive pump also can normally move in more severe occasion at the secondary separation sleeve piecing devices sensor that leaks hunting.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of under the prerequisite that does not break away from principle of the present utility model, carrying out, these improvements and modifications also should be considered as protection domain of the present utility model.
