Abstract

PURPOSE:To enable a vacuum pump to be demounted from or to be mounted to a vacuum chamber even by one person with easy by providing a vacuum pump main body with leg sections which are freely lifted, in the vacuum pump which is mounted onto the vacuum chamber while being spaced from the floor. CONSTITUTION:In a device in which an oil diffusion pump 3 is detachably fixed onto the lower surface of a vacuum chamber 1 while the vacuum chamber 1 is spaced from the floor 2, when the oil diffusion pump 3 is to be demounted from the vacuum chamber 1, leg sections 5 which are normally lifted upward, are lowered downward, rollers 9 are grounded on the floor surface 2, and the leg sections 5 are suitably fixed onto each arm 8 by fixing means so as to be moved by no means at this position. In a state that an oil diffusion pump main body 4 is supported by a plurality of the leg sections 5, a bolt 7 is pulled out of a flange 6, the oil diffusion pump 3 is then demounted from the vacuum chamber 1. In the second plate, the oil diffusion pump main body 4 is gradually lowered down along the leg sections 5, so that the upper surface of the oil diffusion pump main body 4 is thereby separated from the lower surface of the vacuum chamber 1. The oil diffusion pump 3 is then moved to a place easy to work via the rollers 9 thereafter.

In addition, if the legs 5 are kept apart from the floor 2, vibrations during operation of the oil diffusion pump 3 will be transmitted through the legs 5, causing noise at the contact area between the legs 5 and the floor 2, or causing noise in the clean room. Prevents dust from building up inside. For example, when removing the oil diffusion pump 3 from the vacuum chamber 1 in order to replace the oil in the oil diffusion pump 3, first see FIG.
As shown in b), the legs 5 are lowered, the rollers 9 are brought into contact with the floor 2, and in this position the legs 5 are fixed to the arms 8 by appropriate fixing means so that they do not move. Also, Koro 9
The stopper also prevents it from moving. thus,
With the oil diffusion pump body 4 supported by the plurality of legs 5, the bolts 7 are removed from the flange 6 and the oil diffusion pump 3 is removed from the vacuum chamber 1, as shown in FIG. 2(c). Next, the oil diffusion pump body 4 is gradually lowered along the leg portions 5, and the upper surface of the oil diffusion pump body 4 is separated from the lower surface of the vacuum chamber 1, as shown in FIG. 2(d). At this time, an engaging portion or the like is provided on the leg portion 5 so that the oil diffusion pump body 4 does not fall below a certain height.
If the oil diffusion pump main body 4 is supported, when the oil diffusion pump main body 4 is lowered along the leg 5, the leg 5 is fixed to the arm 8 by the fixing means between the leg 5 and the arm 8. It saves you the trouble of fixing it. Thereafter, the stopper of the roller 9 is released, and the oil diffusion pump 3 is moved to a position where it is easy to work, as shown in FIG. 2(e). At this time, Koro 9
Since the oil diffusion pump 3 can be moved smoothly by the Easy oil diffusion pump 3
can be extracted. For example, if you want to reinstall the oil diffusion pump 3 on the bottom surface of the vacuum chamber 1 after replacing the oil in the oil diffusion pump 3, reinstall the oil diffusion pump 3 on the bottom surface of the vacuum chamber 1 by reversing the above procedure. Just install it. In this case, if the legs 5 are threaded rods, the oil diffusion pump main body 4 can be easily raised by turning the legs 5, but if the oil diffusion pump 3 must be lifted manually, A jack or the like may be used as an auxiliary aid.
