Chinese1. Test method-check the capacity of the existing air compressor
Timing pumping test is a relatively easy and accurate method to check the air volume or output of existing air compressors, which will help determine that the shortage of compressed air is not caused by machine wear or failure.
The following is the procedure for timing pumping test:
A. Volume of gas storage tank, cubic meter
B. The volume of the pipeline between the compressor tanks in cubic meters
C. (A and B) Total volume, cubic meters
D. Compressor running at full load
E. Close the air valve between the air tank and the factory air system
F. The gas storage tank is abandoned and the pressure is reduced to 0.48Mpa (G)
G. Close the bleed valve soon
H. The time required for the gas storage tank to pump gas to 0.69Mpa (G), seconds
Now you have the data needed to determine the actual capacity of the existing compressor. The formula is:
C=V(P2-P1)60/(T)PA
C= Compressor air volume, m3/min
V=volume of gas tank and pipeline, m3 (item C)
P2=final load pressure, Mpa (A) (H item + PA)
P1=Initial pressure, Mpa (A) (F term + PA)
PA=Atmospheric pressure, Mpa(A) (0.1Mpa at sea level)
T=time, s
If the calculated result of the test data is close to the rated air volume of your factory's air compressor, you can be more certain that the load of your factory's air system is too high and you need to increase the air supply.
2, estimation method
V=V gas consumption of existing equipment + V gas consumption of post-processing equipment + V leakage volume + V reserve volume
3. Determine the additional compressed air required
According to the amount of air that increases the system pressure to the required pressure, the amount of compressed air supply that needs to be increased can be determined.
P2
Required m3/min= existing m3/min
P1
In the formula, the required m3/min = the required compressed air supply
Existing m3/min = Existing compressed air supply
P2=Required system pressure, Mpa(A)
P1=existing system pressure, Mpa(A)
Need to increase m3/min=required m3/min-existing m3/min
The result will tell you how much gas you need to increase in order to meet the existing gas demand. It is recommended to increase enough gas to not only meet the current gas requirements, but also take into account the needs of rewards and leakage factors.
