Abstract
The invention provides a wind speed, wind pressure and wind volume measuring pipe which comprises a full-pressure cavity (1) and a static pressure cavity (2). The wind speed, wind pressure and wind volume measuring pipe is characterized in that one end of the full-pressure cavity (1) is closed, and the other end is communicated with a micro differential pressure sensor transmitter through a full-pressure joint (4); at least two full-pressure sampling holes (3) are arranged on the windward side of the side wall of the full-pressure cavity (1); one end of the static pressure cavity (2) is closed and the other end is communicated with the micro differential pressure sensor transmitter through a static pressure joint (5); and at least two pairs of static pressure sampling holes (6) are arranged on two faces of the side wall parallel with the wind direction of the static pressure cavity (2) correspondingly. A plurality of sampling holes are arranged on the full-pressure cavity and the static pressure cavity, therefore, averages of full pressures and static pressures of all points in a line can be measured by one measuring pipe, and the measurement data has high reliability.
Description
Technical field
The present invention relates to a kind of measuring wind speed element, relate in particular to wind speed, blast, air measuring element in a kind of air cleaning unit.
Background technology
In air cleaning unit, be provided with flow measurement device, wind speed, blast, air quantity are measured.In the prior art, the main measuring sensor that adopts in the flow measurement device is a pitot tube.Usually adopt a plurality of pitot tubes to gather the total head and the static pressure of each point in the straight line, send into respectively again and obtain total head mean value and static pressure mean value in total head chamber and the static pressure chamber.There are the following problems with pitot tube measuring wind, blast, air quantity: 1, because each pitot tube can only record the total head value and the static pressure of a point, the mean value of trying to achieve whole wind speed, blast and air quantity just needs to use a plurality of expensive pitot tube measuring sensors, and financial cost is higher; 2, a plurality of pitot tube occupation space are big, the complex structure of entire measuring device, and volume is big; 3, the pipeline configuration of pitot tube inside is bigger to the data influence of measuring, so manufacture craft is strict, the cost of manufacture height.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of can disposable accurate measuring wind, the measuring sensor of blast, air quantity mean value.
The object of the present invention is achieved like this: a kind of wind speed, blast, volume measuring pipe, comprise total head chamber and static pressure chamber, and it is characterized in that: the end sealing in described total head chamber, the other end is communicated with minute-pressure difference sensing transducer by the total head joint; The windward side of described total head chamber sidewall is provided with 2 above total head thieff hatchs;
The one end sealing in described static pressure chamber, the other end is communicated with minute-pressure difference sensing transducer by static pressure inlet; The corresponding static pressure thieff hatch that is provided with more than 2 pairs on two faces that are parallel to wind direction of described static pressure chamber sidewall.
For total head mean value and the static pressure mean value that can measure each point on the straight line, described wind speed, blast, volume measuring pipe are preferably linearity.
According to measuring needs, described total head thieff hatch is traditionally arranged to be 5～12, and described static pressure thieff hatch is generally 5～12 pairs, and each total head thieff hatch and corresponding a pair of static pressure thieff hatch coplane; The density degree in pore size and hole can be according to the needs setting of measuring.
Among the present invention, the cross sectional shape in total head chamber and static pressure chamber can be provided with as required, and the cross section in described total head chamber generally can be selected circle, square, rhombus or abnormity for use; The cross section in described static pressure chamber generally can be selected circle, square, rhombus or abnormity for use.
Beneficial effect of the present invention is:
1, the present invention can measure the total head and the static pressure mean value of the each point in the straight line by a measuring tube by on total head chamber and static pressure chamber a plurality of thieff hatchs being set respectively, and the reliable measuring data height is convenient and practical;
2, preparation technology of the present invention is simple, and not high, easy to process to the precision requirement of inner structure, financial cost is low;
3, total head measuring tube of the present invention and static pressure tube are wholely set, and have saved the space greatly, simplify the structure.
