Abstract
The utility model relates to a lift formula anemometer suitable for ventilation blower amount of wind on-line measuring sets up a pivot on the tuber pipe according to the lift that produces when the wind current flows the wing and the proportional principle of wind speed square, and epaxial being fixed with the wing, the wing can produce a lift during the wind current flows, connects epaxial torque sensor through, measures the produced lift moment of flowing the wing, can obtain the amount of wind after converting into the wind speed. The air gauge is reliable in operation because a pressure measuring hole which is easy to block is eliminated, and is very suitable for on-line monitoring of the air quantity on site under severe conditions.
Description
The utility model relates to a kind of flow measurement meter, a kind of lift formula air volume meter that is used for the ventilation blower air-quantity measuring of more specifically saying so.
Traditional measurement of fluid flow, difference according to measuring principle, can be divided into positive displacement, differential, ultrasonic type, electromagnetic type etc., and the on-line measurement of on-the-spot all kinds of ventilation blower air quantity at present all is that employing is differential basically, promptly by measuring the pressure reduction between ad-hoc location in the air channel, after being converted into wind speed, just can get outflow.Yet, because field condition is abominable, distinguished and admirable in impurity, dust a lot, pressure tap is very easily blocked, thereby causes flowmeter to lose efficacy, thereby its reliability extreme difference.
The purpose of this utility model provides a kind of lift formula air volume meter that designs according to distinguished and admirable lift that produces when streaming wing and the wind speed square principle that is directly proportional.
The purpose of this utility model can realize in the following manner: a kind of lift formula air volume meter that is applicable to the on-line measurement of ventilation blower air quantity, include axle, and it is installed on the tested air channel, is fixed with wing on the axle, is connected with torque sensor at an end of axle.
The utility model compared with prior art has following advantage: this air volume meter is owing to cancelled the pressure tap that obstruction takes place differential air volume meter easily when measuring, and adopted wing, utilize the distinguished and admirable lift that produces when streaming wing and wind speed square to be directly proportional, with a torsional moment sensor, measure and stream the lifting moment that wing produces, be converted into get final product behind the wind speed air output, thereby reliable operation is very suitable for the on-the-spot air quantity on-line monitoring of inclement condition.
Description of drawings:
Accompanying drawing 1 is a structural front view of the present utility model.
Accompanying drawing 2 is A-A cut-open views of Fig. 1.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing 1,2: a kind of lift formula air volume meter that is applicable to the on-line measurement of ventilation blower air quantity, include axle 3, it is installed on the tested air channel, is fixed with wing 2 on the axle 3, and an end of axle 3 is connected with torque sensor 1.This lift formula air volume meter is to produce a lift F when streaming wing according to distinguished and admirable, and lift F is directly proportional with wind speed V square, can measure the lifting moment that wing 2 is produced by torque sensor 1 in airduct, can be converted into get final product behind the wind speed air output.
Claims (1)
