Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for installing a rotating machine in which a vertical rotating body is housed in a cylindrical container.

(Prior Art) As a method for installing a rotating machine in which a rotating body is housed in a cylindrical container, the method shown in FIG. 1 is generally considered. That is, the flange 2 is connected to the lower end of the rotating machine 1, and the flange 2 is firmly fixed to the foundation 4 with anchor bolts 3.

(Problems to be Solved by the Invention) With this method, if the rotating body housed in the container is damaged, it is not possible to buffer the vibration force, and when a large number of rotating machines 1 are arranged in a group, the adjacent rotating bodies has the disadvantage of transmitting vibration waves.

The present invention has been made to eliminate the above drawbacks, and provides a method for installing a rotating machine that can prevent vibration waves from being transmitted to other adjacent rotating machines even if the built-in rotating body is damaged. There is a particular thing.

[Structure of the invention]

(Means for Solving the Problems) That is, the present invention covers a rotating machine in which a vertical rotating body is rotatably housed in a cylindrical container having upper and lower end plates with a pair of upper and lower covers, so that the rotating machine has a radial radius. An object of the present invention is to provide a method for installing a rotating machine, characterized in that the pair of covers fit and support the rotating machine in a dowel shape with a pressing force sufficient to allow rotation in a direction, and the rotating machine is installed on a foundation.

(Example) Hereinafter, the first method of installing a rotating machine according to the present invention will be described.
An example of this will be explained with reference to FIG. Both the upper and lower ends 5 and 6 of the rotating machine 1 are formed into cylindrical parts, and the rotating machine 1 is protected from above and below by a lower cover 8 having a counterbore part 7 that can form a dowel shape with the cylindrical part, and an upper cover 10 having a counterbore part 9. After fitting, bolts 11 are screwed into screw holes 12 formed in the upper cover 10 to support the rotating machine 1 between the covers 8 and 10.

The upper cover 10 and the lower cover 8 are fixed with long bolts 13, and the lower cover 8 is fixed to the foundation 4 with anchor bolts 3. The rotating machine 1 is pressed vertically by a push bolt 11, but is rotatably supported.

In the above configuration, the rotating machine 1 is fitted into the counterbore portions 7 and 9 of the upper cover 10 and the lower cover 8, and is restrained in the left and right direction by the dowel and in the vertical direction by the push bolts 11. The rotating machine 1 can rotate relatively freely in the rotational direction.

If the rotating body of the rotating machine 1 is damaged by installing the rotating machine 1 in the manner described above, the vibration force can be converted into rotational torque by rotating the rotating machine 1 within the fitting. It can absorb vibration energy and weaken the transmission of vibration force to adjacent rotating machines. In other words, even if one rotating machine is damaged, by buffering the vibration force, it is possible to prevent the influence on adjacent rotating machines.

Next, a second embodiment of the present invention will be described with reference to FIG. The upper end surface of the rotating machine 1 is provided with a recess 13 that fits into the cylindrical end of the push bolt 11 attached to the upper cover 10, and the lower end surface of the rotating machine 1 is fitted into a recess 15 provided on the lower cover 8. The cylindrical convex portion 14 is provided so as to. This embodiment has the advantage that the recesses 13 and 15 can be formed to have smaller diameters than the embodiment shown in FIG.

Further, a third embodiment of the present invention will be explained with reference to FIG. T-shaped recess 16 in the lower end plate 6 of the rotating machine 1
A T-shaped bolt 17 inserted through a hole 19 formed in the lower cover 8 is inserted into the recess 16, the head of the bolt 17 and the recess 16 are fitted, and the nut 18 is inserted from the lower surface of the lower cover 8. An example is shown in which the bolt 17 is tightened. In this embodiment, the rotating machine 1 has bolts 17
Although the vertical movement of the rotary machine 1 is restricted by the lower cover 8 at the head thereof, and the cylindrical portion of the bolt 17 is restricted from left to right by the cylindrical portion of the bolt 17, there is a degree of freedom for movement in the rotational direction of the rotary machine 1.

Therefore, there are effects similar to those of the previous embodiment. This embodiment is useful when a connecting part such as a pipe is provided at one end of the rotating machine 1.

〔Effect of the invention〕

According to the present invention, the vibration force of a built-in rotating body is buffered by a rotating machine that can rotate relatively freely in the rotational direction of the rotating body, thereby preventing transmission of vibration to adjacent rotating machines. Can be done. Therefore, it is possible to install a large number of rotating machines in a dense manner, and the overall size and installation area of the apparatus can be reduced.
