Description
Technical field
The present invention relates to a kind of air-conditioning duct flow speed controller, belong to fluid monitoring field.
Background technology
In the use of large-scale air temperature control and recycle unit, list central authorities' air duct type air-conditioning in, often can use more airduct and carry out leading wind, simultaneously in order to realize the object such as air filtration and heat exchange, the parts such as filtering net, heat exchange fin and drainage blower fan can be added in airduct, in order to monitor the normal operation of items of equipment and element, all kinds of flow monitor can be installed in pipeline, while realizing being monitored by flow rate of pipelines, it is possible to realize the automatic control to equipment such as drainage blower fan, interchanger in pipeline;
Traditional gas flow rate meter is generally wind meter, and its ultimate principle is put in a fluid by the wire that thin, galvanization heating of metal silk so that it is wire wind meter, higher than the temperature of fluid, is therefore called " hot line " by temperature. When fluid vertically flows through wire, a part of heat of wire will be taken away, make wire temperature decrease. Theoretical according to forced convection heat exchange, can derive and there is relational expression between hot line dispersed heat Q and the speed v of fluid. The hot line probe of standard is made up of two support tensionings short and thin wire.
This type of wind meter mainly adopts the temperature difference to realize the measurement to wind speed, but in the use of the equipment such as air-conditioning, because the temperature of air is real-time change, so the wind meter of this class formation is in the use of mechanism, data deviation can be relatively big, and for the conditioning unit that the large-scale interior space uses, often gas humidity is bigger, the hot line of the velocimeter of this kind of structure is easy to corrode, and causes the inaccurate of data;
In addition, also has the velocimeter of a kind of vane type, by different in flow rate flow velocity, the motivating force difference of impeller is realized monitoring, this kind of velocimeter generally adopts a drives impeller constantly rotated in a fluid, flow velocity is obtained by the rotating speed of drives impeller, its agent structure comprises impeller and an electric generator structure rotated, structure is simple, with low cost, it is applicable to some profits low, usage quantity is big, the factory that data accuracy requirement is not high, but also there is bigger shortcoming in mechanical velocimeter, in order to reduce the difficulty of digital simulation, the rotation axis of general impeller and the axis coaxle of pipeline, fluid head-on flows towards impeller, so the decay that impeller brings to rate of flow of fluid in pipeline is very huge, the flow velocity in pipeline not only may be made cannot to reach working index, the flow velocity of this kind of structure neither be very accurate simultaneously, generally can only according to the tail pipe position at pipeline structure, use range is also very little,
Such as a kind of mechanical velocimeter that ZL201110251948.0 proposes, it adopts a large-scale impeller to realize the detection to flow velocity, this velocimeter flow resistance is bigger, the lift demand of fluid driven impeller is higher, and the flow rate attenuation brought by whole pipeline is also bigger, in addition, this velocimeter is it is generally required to be connected in series in pipeline, if needing to be installed by existing pipeline, so need to dismantle existing pipeline, integrated engineering amount is bigger, if the quality rotating the velocimeter impeller of formula in addition is not high, also certain shake can be brought to pipeline during rotation, affect the life-span of pipeline.
