Embodiment Construction

[0016] An embodiment of the connection unit of the present invention and an embodiment of a gas compressor using the connection unit of the embodiment (corresponding to one embodiment of the gas compressor of the present invention) will be described below with reference to the drawings.

[0017] 1 is a diagram of a compressor 100 in the form of an impeller rotor as an embodiment of the gas compressor of the present invention, along the lines described later. image 3 A cross-sectional view of the A-A line; Fig. 2 is an enlarged view of the details of the B part in Fig. 1; image 3 is the side view in Figure 1.

[0018] The illustrated compressor 100 is configured by accommodating a compressor main body 60 for compressing gas in a housing space inside the casing 10 .

[0019] Here, the casing 10 is composed of a substantially cylindrical box body 11 with one end open and a front end cover 12 that covers the open end of the box body 11 to form a closed storage space inside, as sh...

Abstract

In a gas compressor, a fastener part is fastened by a fastener member comprised of a bolt coated with a zincate bath and a gasket, any leakage from the fastener member is prevented, the gas compressor including a case 11 and a front head 12 fastened by a first fastener member 80 , a housing 10 having a holding space in the interior portion, a compressor main body 60 that compresses gas held in the holding space and fastened to the housing 10 by a second fastener member 70 , the second fastener member 70 being a fastener member comprised of a bolt 71 coated with a zincate bath in combination with a copper gasket 72 coated with tin.

Description

technical field [0001] The present invention relates to a connection assembly and a gas compressor using the connection assembly, in particular, to the improvement of the combination of bolts and sealing gaskets. Background technique [0002] Conventionally, bolts have been used as one of the connecting components, and various plating treatments have been applied to the bolts mainly from the viewpoint of rust prevention and appearance. [0003] It turns out that this electroplating treatment is mainly performed in a chloride bath (=acidic bath: a bath mainly composed of ammonium chloride), but since the chloride bath contains chloride ions, there is COD (Chemical Oxygen Demand: The problem of high chemical oxygen demand. [0004] Therefore, in recent years, from the viewpoint of reducing the environmental load, etc., the above-mentioned chloride baths have been shifted to zincate baths such as completely cyanide-free zinc baths or alkaline zinc baths composed of zinc and so...
