Description

Technical Field

[0001] The utility model relates to the technical field related to oil and gas storage devices, and in particular to an oil and gas tank top cover opening structure. Background Art

[0002] The oil-gas tank of the screw compressor, also known as the oil-gas separator or oil-essence separator, is an important component of the compressor system. It is responsible for separating the oil and gas in the compressed oil-gas mixture.

[0003] Existing screw compressors use a top cover opening mechanism for oil and gas tanks. This mechanism involves creating a through-hole of a certain depth in the tank's top flange, welding a plate with threaded holes to the top cover, and then bolting it together. The bolt is rotated to lift the top cover, which can then be rotated to access the oil separator core within the tank for maintenance and replacement. This bolt-type opening mechanism requires loosening bolts one by one, making it a cumbersome operation that increases maintenance time and labor intensity, and poses safety risks. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an oil and gas tank top cover opening structure, which can more conveniently maintain and replace the oil separator core in the tank body, thereby solving the problems raised in the above-mentioned background technology.
