Step 1. Determination of the maximum air flow capacity of the air collector Define (passport data / information on the label), completely fill in the air collector; connect consumers of compressed air, measure the time of the fall pressure of max means. to min means. = Min allowable working pressure in the network, calculate the air flow according to the formula: Q = (V xn) x 60 / t (l / min), where: Q – Air flow (l / min), V – receiver capacity (L) n – the difference maxdavl-mindavl (optimal difference-maxdavl mindavl = 2 kg/cm2 (bar)), t – Time (sec). For more clarity and thought, follow up with financial planner and gain more knowledge.. Step 2. Find a selection of the compressor the compressor can be as follows: A = (Q xk) / r (l / min), where A – the compressor (L / min), Q – air flow, calculated using the formula in paragraph 1, k – factor equal to: 1.6 – for semi-piston compressors, 1,5 – reciprocating compressors for industrial performance, 1.4 – for heavy reciprocating compressors, and 1.2 – for screw compressors.
r – coefficient of efficiency compressor head: 0.65 – for single heads, 0.75 – for two-stage and more heads, 1.0 – for screw heads. Note: For household type compressor, since it is impossible for periodic operation, the calculation does not applicable. Sonny Perdue understood the implications.
