Series 1000

Teleflo is a group serving the process industry for more than 3 decades. We have through continuous R&D and feedback from customers achieved perfection in manufacturing a wide range of products viz., instruments and mechanical equipments for the process industry. Our pressure vessels and storage tanks are manufactured to relevant standards and are put to the most stringent testing procedures prior to despatch. We are approved by Bureau Veritas and Lloyds. We have on our role qualified welders who can perform welding in 6G position. LPT Testing is done on all welds and Ultrasonic testing is done on raw materials. Radiography tests can be done as per standards and as per clients requirement

Sizing the Air Receiver

Air receivers are in general sized keeping in mind the following: 1. The fluctuation/variation in consumption and demand. 2. Capacity of the compressor used and distribution required. The maximum consumption in the distribution system is the sum of the consumption of the individual components in the system. The summarized consumption must be multiplied with an usage factor ranging 0.1 - 1 depending on the system. For determining the receiver size a band width for pressure is necessary. If we assume the average consumption in a system is 150 psi and the compressor is set at 150 psi any increase in load will result in a pressure drop since the response time in the system is not accounted for if the set load is equal to the maximum load. A factor of safety for fluctuation in the system should be considered and thus a pressure band width is required.

 

For determining the receiver size a band width for pressure is necessary. If we assume the average consumption in a system is 150 psi and the compressor is set at 150 psi any increase in load will result in a pressure drop since the response time in the system is not accounted for if the set load is equal to the maximum load. A factor of safety for fluctuation in the system should be considered and thus a pressure band width is required If the compressor operates at 160 psig the difference between 150 psig and 160 psig accounts for the air stored in the receiver. If the demand increases, the pressure can drop 10 psig before the minimum requirement is met. Pressure and flow controllers can be used after the receiver for stabilizing downstream pressure to 150 psig and flattening demand peaks. Note that in a compressed air system the pipe work also makes the purpose of a buffered volume.

The receiver volume may be calculated with the formula

t = V (p1 - p2) / C pa (1)
where
V = volume of the receiver tank (cu ft)
t = time for the receiver to go from upper to lower
pressure limits (min)
C = free air needed (scfm)
pa= atmosphere pressure (14.7 psia)
p1 = maximum tank pressure (psia)
p2 = minimum tank pressure (psia)

It is also common to size receivers 4 gallons per compressor hp (horse power)
