Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to an oil-gas separator whose core is convenient to replace. Background Art

[0002] The oil-gas separator is one of the important components of the entire submersible electric pump system. Its function is first to serve as the suction port for oil and gas to enter the multi-stage centrifugal pump. Secondly, before the mixed gas liquid enters the multi-stage centrifugal pump, the separator separates the free gas from the well fluid, thereby reducing the impact of the gas on the working characteristics of the submersible electric pump, preventing the centrifugal pump from generating cavitation and gas lock, and enabling the multi-stage centrifugal pump to work normally. After searching, a Chinese patent with the authorization announcement number CN214415667U discloses an oil-gas separator that is convenient for replacing the oil-gas separator core, including a base, the top of the base is fixedly connected to an oil-gas barrel, the top of the oil-gas barrel is movably connected to an attached cover, the inner wall of the oil-gas barrel is clamped with a separator core, the inner wall surface of the oil-gas barrel is fixedly connected with a clamping block, the surface of the separator core is fixedly connected with a clamping ring, the inner wall of the clamping ring is provided with a slide groove, and the left surface of the clamping block is fixedly connected with a fixed block. The oil-gas separator, which is convenient for replacing the oil-gas separator core, can complete the disassembly of the oil-gas barrel and the separator core by pressing the pressing column, so that the separator core can be replaced and cleaned later. At the same time, the workload of workers when replacing the separator core is reduced, the workload and difficulty of the workers are greatly reduced, and the efficiency of the separator core replacement process is improved, thereby reducing the cost of users.

[0003] However, in actual use, this solution lacks fixing facilities for the attached cover, which makes the attached cover easy to loosen. Once the attached cover falls off, the internal separator core will be exposed to the air, thereby attracting dust and impurities, which is not conducive to subsequent assembly and use.
