The air reaches the center of the impeller. 3. Centrifugal Compressor is a machine in which a particular gas or vapor is compressed by a radial acceleration by an impeller with the help of a surrounding case. THIS TEXT PROVIDES YOU KNOWLEDGE OF DIFFERENT TYPES OF COMPRESSORS AND THERE WORKING PRINCIPLES. As it is a positive displacement machine, high-pressure refrigerants, such as R-22 and ammonia are used in it. 0000022094 00000 n 0000001896 00000 n 0000004275 00000 n startxref Multi-stage, "beam" style compressors require two seals, one at each end of the shaft (Fig. The air is entrapped in the 'compartment' formed by a male lobe and a female flute. 0000011471 00000 n 0000003761 00000 n hޔU[lRwÿÎáàŠçpQG¡žBK¡,Ðkbجf[B'¥-ՖVÚ¼”Â,Ø¢ÇNmÕÍâeÙ˲Ô=m‹K–-{2[šÍ_–ìÁ—e—4YMödܳËÜ÷Áºé´¿øÃÿwû¾ÿ9 Ð Ÿ‚€‹M Ã%ão:à@wµÞß®1ؼóËjáÁÜoßûã{ÎíW¿]Ýz½kañÖí͗_yð±;¶ôÕµ£/Ý8õS±= 7—’;å[ýŸuþòeÝ¡ÍË/kЋ²:Òj2=‰èÈ@¯±ÂbŸìpÔÔºêê½;š=ÖJ›½j»R틄ãÉöo¾ÕçO7 ÅÜ{½±ß9¸¯ûp ôàð˜Eϱ¡”À› …¼¨ÕÈў©LÖ栘«…jÃqJ&}$a­LG†bövÓÜàtÎ}|æØìєÀÊù‚Ès!ƒ^«™œÊŽWËIˆÆsGQÇ7Cx$ž¤ V'EÌê{ÄP 0000527128 00000 n 0000474211 00000 n xref So, how does a centrifugal compressor work? 0000065473 00000 n 255 80 Report.

Compressor Handbook Principles and Practice by Tony Giampaolo. The core component of a centrifugal compressor is the rotating impeller. The specific compression energy transmitted to the gas by the impeller is called "head." The compression is largely influenced by a centrifugal pump. 1. 0000402358 00000 n 0000002307 00000 n 0000009064 00000 n Optimize the operation efficiency of your compressors . The compressor is driven by a 1750 RPM,3-phase,60 Hz, 460 V motor thru V- belts with transmission efficiency of 95%. Diffuser gradually reduces the air velocity. Axial flow compressor also works on the same principle on which centrifugal compressor works i.e. The screw compressor combines many advantageous features of both centrifugal and compressors, along with some of its own. 0000012763 00000 n 0000201498 00000 n Air is drawn into the center of a rotating impeller with radial blades and is pushed toward the center by centrifugal force. 0000000016 00000 n Working Mechanism of a Centrifugal Pump A centrifugal pump is one of the simplest pieces of equipment in any process plant. 0000008050 00000 n 0000472010 00000 n It works on the principle of forced vortex flow. At any point in the flow of air through the impeller the centripetal acceleration is obtained by a pressure head so that the static pressure of the air increases from the eye to the tip of the impeller.
