Portable air speed measuring apparatus of pipeline

Abstract

The invention discloses a portable air speed measuring apparatus of a pipeline. The air speed measuring apparatus comprises a detection bar, a static pressure bar, a total pressure bar and an air speed digital display, wherein the length of the detection bar is adjustable and the detection bar is connected with the air speed digital display respectively through the static pressure bar and the total pressure bar. According to the portable air speed measuring apparatus of the pipeline, disclosed by the invention, an air speed detecting element is composed of a plurality of circular equal pressure pipes in a sleeve joint manner, so as to realize the test of a pipeline air speed, greatly improve the testing efficiency and have the synchronism of testing; the detection bar can be adjusted according to the size of an air pipe so that an applicable range is enlarged; by utilizing a digital display mode, the pipeline air speed can be directly displayed and the field numerical reading can be realized. Compared with other similar test devices, the air speed measuring apparatus has the advantages of high measurement efficiency, accuracy, convenience and fastness and the like, has a very strong real meaning in engineering practice, and has great promotion effects on the development in fields of ventilation and air conditioner, particularly a testing technology of the air speed in the pipeline.

Description

technical field [0001] The invention belongs to the technical field of wind speed measurement, and relates to an anemometer, in particular to a portable pipeline anemometer. Background technique [0002] As people's requirements for the indoor environment are getting higher and higher, the control of the air-conditioning system is getting more and more attention. In order to create a better indoor environment, it is often necessary to accurately measure and analyze the wind speed in the air-conditioning duct during the completion acceptance and normal operation of the air-conditioning system. [0003] At present, the most commonly used method for people to measure the wind speed in the air duct is to use the pitot tube anemometer to test point by point. The disadvantage of this method is that there are many measuring points to be tested, and the range of air duct sizes that each specification of Pitot tube can test is limited. It is often necessary to replace Pitot tubes of...
