Stainless steel corrugated oil storage tank and manufacturing process thereof

Abstract

The invention relates to a stainless steel corrugated oil storage tank and a manufacturing process thereof. The process comprises the following steps: (1) blanking; (2) welding stainless steel plates to form circular pipes; (3) corrugating; (4) shaping; (5) drawing corrugated pipes into a rectangular shape; (6) compressing; (7) stacking the two corrugated pipes together and well welding; (8) welding the connecting surfaces of the two corrugated pipes; (9) welding an upper panel and a lower panel; and (10) performing leakage testing. The stainless steel corrugated oil storage tank is formed by welding at least two joints of the corrugated pipes, the upper ends and lower ends of the corrugated pipes are respectively hermetically connected with the upper panel and the lower panel, and an exhaust pipe interface is arranged on the upper panel; and pulleys are arranged on the two sides of a core body, and a counterweight block is arranged on the upper surface of the core body. The pulleys are arranged on the two sides of the stainless steel corrugated oil storage tank disclosed by the invention, and when the stainless steel corrugated oil storage tank is mounted, the pulleys can be matched with tracks for use, so that the stability of the core body is good when the core body extends and contracts up and down, the core body can be kept vertical longitudinally during long-term use, and the phenomena of inverted waves and damages caused by pulling can be avoided. The stainless steel corrugated oil storage tank disclosed by the invention has the advantages of high space utilization rate, aesthetic and elegant appearance, low manufacturing and mounting cost, and safety and reliability in working.

Description

technical field [0001] The invention relates to a power transformer device, in particular to a stainless steel corrugated oil storage tank for a transformer and a production process for manufacturing the stainless steel corrugated oil storage tank. [0002] Background technique [0003] On May 2, 2001, Chinese patent CN1065351C disclosed the invention patent of "Bellows type transformer oil conservator". This patent mainly installs a metal bellows in the transformer oil conservator, uses the change in the internal volume of the elastic element when it expands and contracts to realize the volume compensation of the transformer oil, and welds the bellows assembly on the bottom surface of the oil conservator shell , the oil inlet pipe is fixed on the bellows assembly. The metal bellows installed in the oil conservator of the above invention is a circular pipe-shaped bellows, while the transformer oil conservator is usually a cuboid structure, which will result in a smaller vo...

AI Technical Summary

Problems solved by technology

The metal bellows installed in the oil conservator of the above invention is a circular pipe-shaped bellows, while the transformer oil conservator is usually a cuboid structure, which will result in a smaller volume of the metal bellows, or a larger volume of the transformer oil conservator. That is, the space utilization rate of the oil conservator is low, which is not conducive to the transportation and installation of the transformer oil conservator, and its manufacturing and installation costs are relatively high
