Attach it detachably and attach the jacket,
An inlet for introducing a fluid between the outer wall of the motor and the jacket and an outlet for discharging the fluid are provided on the outer peripheral portion of the jacket, and a fluid such as hot water, water, or air flows from the inlet. Another object of the present invention is to provide an electric pump with a shacket, characterized in that piping such as a hot water pipe, a water pipe, and an air pipe is formed so as to be connectable so as to flow out from an outlet.

[0006]

When the electric pump with a jacket according to the present invention is used, at least an outer peripheral portion of the motor portion is provided with a space portion for transmitting heat generated by the motor portion to the fluid and flowing the fluid. By covering the jacket, the fluid can be warmed by using the heat generated as the exhaust heat of the motor portion, and the motor portion can be prevented from being overheated.

[0007] Further, by mounting the jacket on the flange of the pump section by overlapping the flange section of the motor case via the flange, the jacket can be easily covered with the electric pump and noise can be reduced. Warm water, water, air, etc. can be flowed in through the inlet and outlet at the outer periphery of the jacket according to the construction environment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments. FIG. 1 shows an embodiment of the present invention. The electric pump 1 has a pump unit 3 connected to a motor unit 2 so as to be driven to rotate by magnetic coupling as shown in FIG.
This is an example of a magnet pump having a lures structure.

The outer periphery of the motor portion 2 is covered with a motor case 4 made of an aluminum material or a stainless steel material surface-treated for water resistance and durability. On the outside, a cylindrical jacket 5 integrally formed of a resin material of engineering plastics such as ABS is provided as a motor case 4.
Is detachably covered with a fixture 7.

As shown in FIG. 1, the jacket 5 has a cylindrical shape slightly larger than the motor case 4 and has a motor shape.
A space 8 having a predetermined gap between the case 4 is provided.
A double cylindrical shape is provided along the outer periphery of the motor case 4 so as to be attached to the motor case 4 at the flange 9 as described above.

As shown in the figure, an inlet 10 and an outlet 11 are respectively provided on one side of the jacket 5 to protrude therefrom, and by connecting necessary pipes, a fluid such as hot water, water, air or the like is supplied to the jacket 5. Can be circulated in the space 8 inside.

Therefore, as shown in FIG. 2, for example, piping is connected to the pump section 3 so as to circulate hot water to an air conditioner (not shown), and circulation pipes are connected to the inlet 10 and the outlet 11 of the jacket 5. During operation, even if the motor part 2 generates heat, circulating water flows around the outer peripheral part of the motor part 2,
The motor section 2 is cooled, and the motor section 2 can be prevented from overheating.

Further, the motor part 2 is covered with a motor case 4 having no opening on the outer peripheral surface, and the jacket 5 is coated on the outer peripheral part. Noise generated in the section 2 can be reduced.

In order to use the exhaust heat of the motor part instead of the circulation pipe, a waste heat utilization pipe may be connected to heat a required heating part. It is.

If necessary, the suction side of the pump section 3 and the outlet 11 side of the jacket 5 are connected by piping, as shown in FIG. 3, and the pump section 3 sucks preheated hot water flowing through the space section 8. It can take appropriate measures such as feeding hot water to required parts.

[0016]

FIG. 4 shows another embodiment of the present invention. In this embodiment, a motor case 4 having a seal structure extends from the outer peripheral portion of the motor portion 2 to the outer peripheral portion of the pump portion 3, and the above-mentioned jacket 5 is connected to the pump from the motor portion 2. The cover is detachably provided over the portion 3. The jacket 5 is provided with a reinforcing member 12 at an appropriate place and can be appropriately supported on the motor case 4.

[0017]

FIG. 5 shows still another embodiment of the present invention. In this embodiment, the motor cake of the motor unit 2 is
A metal material 13 such as an aluminum material or a stainless steel material is inserted into an appropriate portion of the metal material 13 at an appropriate position, and the metal material 13 is integrally formed. The fins 14 appropriately project as heat exchange fins 14 in the space 8.

In the present embodiment, the heat exchange fins are preferable because the exhaust heat of the motor part can be efficiently transferred to the fluid and the motor part can be effectively cooled. The fins for heat exchange may be provided so that a required fluid flow path can be formed in the space.

[0019]

In this embodiment, the motor section can be cooled while the discharge flow from the pump section is heated by the exhaust heat of the motor section, and the noise of the motor section and the pump section can be suppressed. Things. It goes without saying that the flow passage can be formed via the fin.

In the above, the electric pump of the magnet pump has been described. However, the present invention can be similarly applied to other pumps.

[0022]

As described above, in the present invention, the jacket portion and the flange portion of the motor case are overlapped with each other and can be detachably attached to the flange portion of the pump portion. An electric pump such as a magnet pump can be easily made into an electric pump with a jacket simply by protruding. By connecting a circulation pipe to the inlet and outlet of the jacket, the motor can be cooled and the motor can be prevented from overheating. In addition, the suction side of the pump section and the outlet of the jacket section can be connected by piping, and the preheated hot water flowing through the space section can be sucked by the pump section and the hot water can be supplied to the required section. . In this way, by arranging both the inlet and the outlet in the jacket portion, it can be used in a variety of ways, and in particular, an electric pump such as a magnet pump which easily generates heat can be appropriately constructed according to the purpose. . In addition, hot water, water,
Air or the like can be introduced according to the situation and used as described above.
