Description

TECHNICAL FIELD The present invention relates to a rotary fluid machine including, for example, a blower, a fan, a compressor, a pump, a turbine, an expander, and the like.

[Conventional technology]

FIG. 3 is a structural explanatory view of a conventional fan directly connected to an electric motor. In the figure, reference numeral 5 denotes a casing of a fan directly connected to the electric motor, which is fastened to a driving electric motor 1, and the electric motor 1 is firmly connected to a base plate 6. When inspecting the inside of the fan directly connected to the electric motor, after separating the casing 5 from the electric motor 1, the casing 5 is lifted and removed by an overhead crane or the like (not shown).

[Problems to be Solved by the Invention]

As described above, when the inside of the impeller 11 or the casing 5 is to be inspected in the conventional rotary fluid machine such as a fan directly connected to an electric motor, first, the suction pipe 8 and the discharge pipe 9 connected to the casing 5 are firstly inspected. It is necessary to remove the pipes such as, and then to lift the casing 5 such as the spiral pipe with an overhead crane to remove it, and there is a problem that disassembling and assembling such as performing an inching operation of the overhead crane takes time and time. There is.

[Means for solving the problem]

A rotary fluid machine according to the present invention is intended to solve the above-mentioned problems, and in a rotary fluid machine in which an impeller is directly connected to a driving electric motor, a casing covering the impeller has a slide base and a turntable integrally incorporated. It is characterized in that it is fastened on the base plate via a member.

Further, a rotary fluid machine according to the present invention is a rotary fluid machine in which an impeller is directly connected to a driving electric motor, and the driving electric motor is fastened on a base plate through a member into which a slide base and a turntable are integrally incorporated. It is characterized by the following structure.

[Action]

That is, in the rotary fluid machine according to the present invention, either the casing that covers the impeller or the driving electric motor is mounted on the base plate through the member in which the slide base and the turntable are integrally incorporated in the axial direction of the driving electric motor. A casing that covers the impeller and the impeller without moving a large distance by moving either the casing or the driving electric motor in the axial direction of the driving electric motor and rotating the casing. The inside of the product can be easily exposed for inspection. In particular, when the driving electric motor is moved and rotated, the inspection can be performed without removing the suction pipe and the discharge pipe connected to the casing.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In addition, the members common to the members in FIG.
The same reference numerals as those of the members in FIG. 3 are given and the description thereof is omitted.

FIG. 1 is a mechanism explanatory view of a fan directly connected to an electric motor according to an embodiment of the present invention. In the figure, the fan directly connected to the electric motor according to this embodiment has an impeller 11 as shown in FIG. 1 (a).
Are directly connected to and supported by the shaft end of the electric motor 1, and a part 5 ′ of the casing 5 on the back surface of the impeller 11 is attached to the electric motor 1 and the electric motor 1 is fixed on the common base plate 2.
Further, the casing 5 is fixed on the common base plate 2 via a member 7 in which a slide base and a turntable are integrally incorporated.

When inspecting the inside of the fan directly connected to the electric motor, first, as shown in FIG. 1B, the fastening of the member 7 is released, and the casing 5 is pulled out through the member 7 in the axial direction of the electric motor 1. Next, as shown in FIG. 1 (c), if the casing 5 is rotated by about 90 ° through the member 7, the impeller 11 and the inside of the casing 5 are easily exposed without a large moving distance, and inspection is performed. Will be possible. In addition, a part 5'of the casing 5
Need not be supported by the electric motor 1 as long as it can be detached from the casing 5.

FIG. 2 is a mechanism explanatory view of a fan directly connected to an electric motor according to another embodiment of the present invention. As shown in FIG. 2 (a), the electric motor direct drive fan according to the present embodiment has substantially the same mechanism as the electric motor direct drive fan according to the above embodiment, but the electric motor 1 Is fixed on the common base plate 2 via a member 7 in which a slide base and a turntable are integrally incorporated.

Generally, when the temperature of the fan fluid is high or low, it is more difficult to disassemble and assemble because the heat insulating material is wrapped around the pipes and casing, but in the fan directly connected to this motor, it was connected to the casing. Suction pipe 8 and discharge pipe 9
Even if the pipes are not removed, the motor 1 can be moved axially through the member 7 as shown in FIG. 2 (b), and can be rotated by about 90 ° as shown in FIG. 2 (c). The inside of the impeller 11 and the casing 5 can be exposed without taking a moving distance, and inspection can be easily performed.

The same action and effect can be obtained even if the slide base and the turntable are used together instead of the member 7 in the above-mentioned two embodiments.

〔The invention's effect〕

The rotary fluid machine according to the present invention is configured as described above, and by rotating one of the casing covering the impeller or the driving electric motor in the axial direction of the driving electric motor to rotate the electric motor, a large moving distance can be maintained. Since the inside of the impeller and the casing covering the impeller can be easily exposed for inspection, it can be disassembled and assembled without using an overhead crane, etc., which greatly saves labor and time. Is played.
