Abstract

The invention provides a rotating device applied to high pressure scene and a fluid flow machine using the rotating device, in the rotating device, an eccentric axis moving cavity and a piston moving cavity are separated, a bearing can be arranged in the axial direction of the eccentric axis moving cavity, due to the axial length of the eccentric axis moving cavity is greater than the axial length of the piston moving cavity, bearing arrangement number and flexibility are can be n expanded in great space, multi-bearing withstanding pressure is naturally increased, pressure bearing capacity of the fluid flow machine using the rotating device is greatly improved, the rotating device can be applied to the high pressure scene, and the rotating device has practical work life.

Description

technical field [0001] The present invention relates to the mechanical field, in particular to a rotating device suitable for high-pressure scenes and mechanical devices using the same, such as pumps, compressors, fluid motors and engines. Background technique [0002] In order to enhance oil recovery in oilfields, early water injection has been proven to be a very effective method. The formation pressure can be increased through early water injection, so that the oil layer has a strong oil displacement condition, and can maintain a high oil layer pressure, so as to achieve the purpose of high and stable production of the oil field. [0003] In recent years, the development of shale oil and shale gas has boomed rapidly. The most common method of extracting shale oil and gas is hydraulic fracturing, which involves injecting high-pressure water, often mixed with chemicals, into oil wells to release trapped oil and gas. At present, more than half of the shale oil and shale ga...
