Abstract

The invention relates to an ejector with adjustable structure parameters. The ejector comprises a working nozzle, a low-pressure air inlet chamber, a straight pipe section, a diffusion chamber and a low-pressure air inlet chamber inlet pipeline. The diffusion chamber is formed by nesting three stages of diffusion pipes, so that a structure of the diffusion chamber can be changed through adjustingrelative positions of the diffusion pipes. The straight pipe section is formed by a basic straight pipe section and two stages of detachable straight pipe sections, so that the length of the straightpipe section can be adjusted through disassembling or installing detachable parts. A low-pressure air inlet chamber wheel disc and a working nozzle wheel disc are connected with the low-pressure air inlet chamber and the working nozzle into a whole; and during assembling, a main body of the working nozzle stretches into the low-pressure air inlet chamber, and a distance between the low-pressure air inlet chamber wheel disc and the working nozzle wheel disc is changed through adjusting an adjustable bolt, so that an outlet position of the working nozzle is adjusted. According to the ejector with the adjustable structure parameters provided by the invention, the structure parameters of the ejector can be correspondingly adjusted according to the change of an operation condition, so that an ejecting performance of the ejector under varying duty operation situations such as natural gas extraction is improved.

Description

technical field [0001] The invention relates to an injector, in particular to an injector with adjustable structural parameters. Background technique [0002] Natural gas plays a pivotal role in the development of the national economy, especially for my country's current energy-saving and emission-reduction strategies. At present, there are high-pressure gas wells and low-pressure gas wells in natural gas mining sites. The injector uses the energy of high-pressure gas wells as a driving force to inject natural gas from low-pressure gas wells, thereby simultaneously realizing the exploitation of high-pressure and low-pressure gas wells. It can not only make reasonable use of the energy of high-pressure wells, but also does not need compressors for pressurized mining. It is a technology for energy saving and emission reduction. [0003] The traditional structure of the injector is mainly composed of a working nozzle, a low-pressure intake chamber, a straight pipe section and ...
