As shown in Fig. 2, Fig. 2 is the structural schematic diagram of air cleaner flow measuring structure provided by the utility model.
The utility model provides a kind of air cleaner flow measuring structure, including filter main body 5, is set to filter
The filter entrance 1 of 5 outer wall of main body is set to the measurement pipeline 4 of 5 gas outlet of filter main body, measures pipeline 4 and filter master
The connecting pin of body 5 is extended with air compressor machine and takes tracheae 3, measures and is fixed with the flow sensing radially stretched on the outer wall of pipeline 4
Device 2.Filter main body 5 is filtered air, and air is imported by the filter entrance 1 of its outer wall, by filtering after self-filtering
The 5 gas outlet export of clear device main body, the connection of 5 gas outlet of filter main body measures pipeline 4 and air compressor machine takes tracheae 3, measures pipeline 5
Flow sensor 2 is fixedly mounted on outer wall, flow sensor 2, which is extend into, to be measured in pipeline 4, to air stream derived from filter main body 5
Amount measures, by be arranged flow sensor 2 with measure pipeline 4 be structure as a whole, due to flow sensor 2 measure position and
The position of filter main body 5 is fixed, and influence of the vehicle air inlet pipeline to charge flow rate measurement point is avoided, so as to filter
The measurement accuracy of 5 gas outlet position gas flow of main body is controlled, and ensure that measurement accuracy.
In one specific embodiment of this case, the sensor peace that frame support flow sensor 2 is offered on the side wall of pipeline 4 is measured
Hole is filled, flow sensor 2, which is mounted at, to be measured on pipeline 4.It measures and presets sensor mounting hole on pipeline 4, flow passes
Sensor 2, which is mounted at, to be measured on pipeline 4, is controlled by position of the sensor mounting hole on measuring pipeline 4, real
The accurate fixation of 2 installation site of existing flow sensor.Meanwhile dismountable flow sensor arrangement, when it breaks down,
Only by being dismantled in the outside flow sensor 2 for measuring pipeline 4, you can realize maintenance and replacement to it, reduce dismounting
The Operating Complexity of air cleaner assy, dismounting facility.
In one specific embodiment of this case, flow sensor 2, which is set to, measures pipeline 4 along its axial middle part.Air filter
The air that clear device is discharged by its gas outlet is circulated by measurement pipeline 4, in order to air cleaner is crossed the charge flow rate of air filtering into
Row is accurate to be measured, and flow sensor 2 is set to and measures gas in pipeline 4 and circulates relatively stable middle part, the position air inflow
Uniformly, the air inflow data measured by flow sensor 2 can accurately reflect data on flows.
In one specific embodiment of this case, air compressor machine takes the installation end of tracheae 3 to be located at and measures pipeline 4 and filter main body 5
The root of connection.Air cleaner gas outlet is arranged air compressor machine simultaneously and takes tracheae 3, in order to avoid air compressor machine extracts filter discharge
Air the air-flow that it is discharged is had an impact, take the installation end of tracheae 3 to be set to air compressor machine and measure pipeline 4 and filter master
The root that body 5 connects.Air compressor machine shunts air derived from air cleaner during taking gas, is taken by air compressor machine
Tracheae 3 is located at the structure design for measuring 4 root of pipeline, and the air for measuring pipeline 4 is flowed into after shunting by 2 position of flow sensor
When, air-flow is stablized relatively, and air velocity is more uniform, eliminates air compressor machine and takes influence of the gas to new charge amount, so as to accurate
Measure air inflow data derived from air cleaner.
In one specific embodiment of this case, flow sensor 2, which is taken with air compressor machine at a distance from the air inlet center of tracheae 3, is
20mm~100mm.Control flow sensor 2 takes with air compressor machine is more than 20mm at a distance from the air inlet center of tracheae 3, to improve stream
The accuracy of measurement can take the position of spatial position flow sensor 2 in tracheae 3 to be adjusted according to air compressor machine.
Preferably, it is 40mm~100mm that flow sensor 2, which is taken with air compressor machine at a distance from the air inlet center of tracheae 3,.
It is measured on pipeline 4 since flow sensor 2 is integrated in, is one by removably connecting and it is affixed measuring pipeline 4
Body does not have extra air inlet pipeline to participate in, the plastic part prepared using pipeline due to measuring between pipeline 4 and air cleaner
Charge flow rate measurement error is controlled.Further, setting measure pipeline 4 in charge flow rate measurement error control ±
In 2%, to ensure the accuracy to air cleaner measurement result.
In order to be accurately controlled to measurement pipe road measurement result, 2 position of flow sensor can be obtained by simulation calculation
Accurate flow.Specifically, it is calibration point, flow 1050m/h, by pneumatics that setting, which measures flow sensor position in pipeline 4,
Machine takes 3 air inlet center of tracheae to be measured with flow sensor 2 and is controlled respectively in 100mm, 40mm, 20mm at a distance from position, surveys
Velocity uniformity in buret road 4 is respectively 0.938,0.938,0.933.When air compressor machine takes 3 air inlet tube hub of tracheae and flow
When the Distance Shortened of 2 position of sensor is to 20mm, velocity uniformity is declined slightly.
Further, by testing influence of the change for measuring verification air cleaner setting angle to measurement accuracy,
The influence and measurement direction of influence to(for) measurement accuracy of the change of pipeline to measurement accuracy after calibration point can be obtained
Such as draw a conclusion：
1, change setting angle and the position of air cleaner, the measured deviation of flow sensor controls in 1%, shows
Flow sensor be integrated in measurement pipe road to before air cleaner pipeline arrangement require it is insensitive.
2, change the vehicle pipeline after flow sensor, the measured deviation of flow sensor controls in 2%, shows to flow
Quantity sensor be integrated in the scheme of measurement pipe road the pipeline arrangement after air cleaner is required it is insensitive.
Flow sensor 2 is integrated in and is measured on pipeline 4, is directly connected to the gas outlet of air cleaner, flow sensing
The measurement accuracy of device 2 is high, and is not influenced by arrangement installation pipeline, it can be achieved that efficiently, reliably measuring.And due to stream
Quantity sensor 2 is good to the consistency of air inlet measurement, can be obtained stable flow sensor measurement by once demarcating,
After traditional air cleaner export air can be saved, the multiple staking-out work to air inflow measurement structure simplifies work, subtracts
Lack vehicle matching parts, it is cost-effective.
