Adjustable plunger type pulsating flow generator

Abstract

The invention relates to an adjustable plunger type pulsating flow generator, which comprises a water tank, an output branch I, an output branch II, an output branch III and a main path IV, wherein one end of a frequency modulation pipeline pump of the output branch I is connected with the water tank, and the other end of the frequency modulation pipeline pump of the output branch I is connected with a stop valve; the output branch II comprises a ball valve and a first check valve; one end of the ball valve is connected with the water tank, and the other end of the ball valve is connected with the first check valve; the first check valve is connected to the output branch III through a tee joint A; a piston connecting rod mechanism of the output branch III is arranged at an inlet of the output branch III; a second check valve is arranged at an outlet of the output branch III and close to the output branch I; and the output branch I and the output branch III are connected to the main path IV through two joints of a tee joint B. The adjustable plunger type pulsating flow generator has the advantages that 1, steady state flow is regulated through the output branch I, and the pulsating flow is obtained through the output branch III; 2, the energy consumption is saved, and the pulsating flow generator is easy and convenient; and 3, the device is simple in structure and can be reliably operated, and the requirements of different pulsating flows can be met.

Description

technical field [0001] The invention relates to an adjustable plunger type pulsating flow generator, which is used to accurately generate periodic sinusoidal square wave pulsating flow in pipelines. Background technique [0002] The core focus of the development direction of heat and mass transfer in the discipline of engineering thermophysics in my country is the three leading technologies that are closely integrated with the development of social economy and science and technology in the world today-biology, information and nanotechnology. At present, the research on pulsating heat transfer focuses on these three aspects. Through the pulsating heat transfer technology, efficient heat dissipation and heat transfer functions can be realized, thermal barrier bottlenecks in important areas can be solved, and energy consumption can be greatly reduced. The research on pulsating heat transfer has gradually entered the micro-nano scale pulsating heat transfer from macro research...

Problems solved by technology

The pulsating flow generator with the domestic patent number "CN200910060614.8" can preliminarily realize the pulsation of periodically changing fluid flow velocity, but the pulsating flow generator can only realize the adjustment of the pulsation frequency, not the adjustment of the pulsation amplitude, and the pulsation The periodic pulsation of the fluid produced by the flow generator is not precise enough
