The use of compressed air flowmeter must avoid the following aspects of adverse factors.
A, big vibration.
Every an air flow meter is not installed in vibration.
But installed in compression workshop and the air flow meter has to consider the vibration problem of blower room.
This mainly comes from the compressor and blower vibration, the vibration of the machine through the air pipe or duct can spread to far away places.
One of the biggest vibration for reciprocating compressor, the vibration of large reciprocating compressor running tend to drive the plant and the surrounding ground vibration together, on the accurate and reliable operation of the air flow meter.
It trigger lever fulcrum mobile differential pressure transmitter and make the instrument drift value.
Vibration caused the vortex flow sensor with vibration frequency corresponding to the interference signal, causing traffic greatly value is on the high side.
Second, gas and water.
Compressed air flow meter are taken from the atmosphere, and always contain a certain amount of water vapor in the atmosphere.
Water vapor content of the water vapor partial pressure ps said.
Atmospheric water vapor saturation pressure is a function of atmospheric temperature.
Outside in the rain and fog, atmospheric water vapor partial pressure of saturated degree, the relative humidity of 100%, then the air compression as oppression absorb enough water in the sponge, with volume reduction, precipitation has a corresponding amount of water.
This is the simple principle of compressed air with water so.
In fine weather, air relative humidity is low, but as it is compressed, shrunk to a sliver of their original size, water vapor partial pressure will rise accordingly, also may enter the saturation state and precipitation water droplets.
Used to measure the compressed air flow of the larger diameter orifice flowmeter, common water before orifice, to affect the measurement accuracy.
Lead has a tendency to a water pressure pipeline, which leads to the differential pressure transmitter to the measurement of differential pressure differential pressure generated by the inconsistent with the throttle device.
These are all air with water a common cause of error.
In addition, due to the urban area with high content nitrogen oxides in the atmosphere, make the compressed air contains water acidic, annulus surface caused by corrosion, pipeline internal corrosion, make its surface becomes rough.
Corrosion of iron oxide dried under certain conditions, it is easy to fall off from the inner wall of the tube and the air flow to the orifice, it will also impact on flow value.
Therefore, when parking overhaul, these should be powder and block junk to be cleared.
Third, pulsating flow.
The compressor and blower outlet fluid most contain certain pulsation.
The reciprocating compressor, for example, show the half wave pulse.
That can be observed at the scene of the compressor and blower outlet pressure have obvious oscillation.
Which is (
)
Displacement blower export pulse frequency is higher, generally speaking, there are dozens of Hertz, and reciprocating compressor export pulsation frequency is low, usually for a few Hertz.
Caused by the pulsating flow differential pressure flowmeter, vortex flowmeter flowmeter in value on the high side, causing the float float flowmeter jumping up and down.
To eliminate and weaken the influence of flow pulsation for the value of the flow meter, there are two commonly used methods, one is in the compressor outlet setting a buffer tank filter ripple, and install the meter in the buffer.
In fact of the reciprocating compressor system is designed so that;
2 it is to install the meter away from the pulse source, it can use the process piping gas capacity with low-pass filter attenuation ripple pipe resistance composition.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
