Embodiment 1
[0035] like Figures 1 to 4 As shown, the cylindrical refrigerant compressor includes a cylindrical welded casing 1, an inner casing 2 and an adjustable guide vane actuator 3. A support ring and a baffle are welded on the inner wall of the cylindrical welded casing 1, and the support ring and the baffle form a volute inside the cylindrical welding casing 1, the inner casing 2 is arranged inside the cylindrical welding casing 1, and a connecting rib group 4 is arranged along the circumferential direction of the shell wall of the inner casing 2 to connect The rib group is used to divide the inner casing 2 into at least two unit inner casings; the adjustable guide vane actuator 3 is arranged in the cylindrical welding casing 1 on the side close to the inner casing 2 .
[0036] The cylindrical welded casing 1 is welded by the Q345R plate, and the Q345R plate is composed of the following chemical composition in weight percentage: C 0.02%, Si 0.3%, Mn 1.2%, P 0.002%, S 0.015% , CaO...
Embodiment 2
[0044]Referring to Example 1, the cylindrical refrigerant compressor provided in this embodiment is different in that the cylindrical welded casing 1 is welded by the Q345R plate, and the Q345R plate consists of the following weight percentages: Chemical composition: C0.2%, Si 0.5%, Mn 1.3%, P 0.01%, S 0.01%, CaO 0.003%, Co 0.16%, Cu 0.03%, Alt 0.02%, V 0.01%, and the balance of Fe and unavoidable impurities.
Embodiment 3
[0046] Referring to Example 1, the cylindrical refrigerant compressor provided in this embodiment is different in that the cylindrical welded casing 1 is welded by the Q345R plate, and the Q345R plate consists of the following weight percentages: Chemical composition: C0.1%, Si 0.2%, Mn 1.6%, P 0.02%, S 0.013%, CaO 0.0025%, Ni 0.4%, Co 0.18%, Cu0.2%, Al t 0.01%, V 0.025% , and the balance of Fe and unavoidable impurities.
