Embodiment Construction

[0031] Hereinafter, the expansion joint and the compression system according to the embodiment of the present invention will be described.

[0032] figure 1 An expansion joint 10 according to the present embodiment and a compression system 11 using the expansion joint are shown. The compression system 11 is provided with a plurality of telescopic connectors 10 with the same structure. When distinguishing these several expansion joints 10, it assigns and distinguishes by code|symbol (A)-(E).

[0033] The compression system 11 is a device that compresses gas to generate compressed gas, specifically, compresses air to generate compressed air. In addition, the compression system 11 may be a device that compresses gas other than air. Such as figure 2 Compression system 11 is shown with motor 15 and compressor 16 . The motor 15 is driven by electricity to rotate a motor shaft 17 .

[0034] The compressor 16 is a multi-shaft multi-stage gear compressor. The compressor 16 has ...

Abstract

An expansion joint (10), which connects pipes to each other and is capable of expanding and contracting, the joint being provided with: a first end pipe (71) and a second end pipe (72); a connecting pipe (73) for connecting the first end pipe to the second end pipe so as to be capable of approaching and separating from each other; and a thrust-absorbing means (74) having a pressure chamber (114), which can expand and contract in the direction in which the first end pipe and the second end pipe are linked and into which a fluid pressure that differs from the pressure inside the pipes can be introduced, the pressure chamber comprising a first pressure-receiving section (116), which is fixed to the first end pipe and faces in the direction from the second end pipe toward the first end pipe, and a second pressure-receiving section (117), which is fixed to the second end pipe and faces in the direction from the first end pipe towards the second end pipe.

Description

technical field [0001] The invention relates to an expansion joint and a compression system. Background technique [0002] Among the connectors that connect pipes, there are expansion joints that absorb the thermal expansion of pipes. The expansion joint has a structure that eliminates the thrust caused by the internal pressure generated in the direction of separating or approaching the pipes. For example, Patent Document 1 discloses an expansion joint using three bellows. The telescopic connector specifically has the following structure. Guide flanges are attached to both ends of one small-diameter bellows. Guide flanges are attached to both ends of the other small-diameter bellows. These small-diameter bellows are arranged in series, and the guide flanges attached to these bellows are connected to each other through the large-diameter bellows. A guide flange attached to the side of the small-diameter bellows opposite to the large-diameter bellows on one side and a gui...
