Abstract
The invention discloses a magnetic drive pump axis which comprises a circular long shaft. A convex shaft sleeve is formed at the tail end close to the circular long shaft, a large convex circle is formed at the bottom end of the convex shaft sleeve to wrap the circular long shaft, a small convex circle is formed at the front end of the convex shaft sleeve, the convex shaft sleeve, the large convex circle and the small convex circle form high and low segment difference, the circular long shaft projects over the front end of the small convex circle, the diameter of the circular long shaft is smaller than that of the small convex circle, the circular long shaft and the convex shaft sleeve are made of integrally formed steel, so that the axis does not easily break in use and is abrasion-resistant, durable and not easily damaged, and maintenance cost is indirectly reduced.
Description
Technical field
The present invention relates to magnetic force driving pump axle center, relate in particular to a kind of magnetic force driving pump axle center of pumping for powder, liquid.
Background technique
Magnetic force driving pump is a kind of pump that can be applicable to high-temperature work environment, tradition magnetic force driving pump is to be coordinated after axle sleeve by the ceramic main shaft of sinter molding, at axle sleeve, lock after establishing impeller and extract action, general magnetic drive pump in running along with main shaft friction produces high temperature and high heat can be delivered to ceramic main shaft and shaft room, thereby generation ruckbildung, and because being unlike material, ceramic main shaft and axle sleeve under high temperature deformation, easily make ceramic main shaft fracture, also can because causing spindle eccentricity to make impeller collide housing, distortion cause the phenomenon that crumbles because of ceramic main shaft and shaft room on the other hand.
Summary of the invention
The object of the invention is to be to provide a kind of magnetic force driving pump axle center, not easy-rupturing of axle center, wear-resisting, durable in use, not fragile, indirectly also reduces maintenance cost.
According to an aspect of the present invention, a kind of magnetic force driving pump axle center is provided, comprise round major axis, circle major axis caudal part forms the convex axle sleeve that is convex shape, and its bottom forms large dome will justify major axis parcel, in its front end, form little dome, poor with large and small dome formation height section, at little dome front end, protrude circle major axis, this circle major diameter is less than little dome diameter, and circle major axis and convex axle sleeve are all that the steel that are integrally formed are made.
The present invention is simple in structure, easy to use, and not easy-rupturing of axle center, wear-resisting, durable in use, not fragile, indirectly also reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation in a kind of magnetic force driving pump of the present invention axle center.
Embodiment
Below in conjunction with accompanying drawing explanation, the present invention is described in further detail.
As shown in Figure 1, a kind of magnetic force driving pump axle center, comprises steel circle major axis 2, on this circle major axis 2, near one end of tail end, forms convex axle sleeve 3.This convex axle sleeve 3 is type form, its bottom forms large dome 4 and will justify major axis 2 and wrap up, in its front end, form little dome 5, just poor with large and small dome 4,5 formation height sections, at little dome front end, protrude round major axis 1, these circle major axis 2 diameters are less than little dome 5 diameters, and circle major axis 1 is all that the steel that are integrally formed are made with convex axle sleeve 2, have firm intensity with towards property.
In sum, the present invention is simple in structure, easy to use, and not easy-rupturing of axle center, wear-resisting, durable in use, not fragile, indirectly also reduces maintenance cost.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
