Note: This root cause analysis (RCA) is from real-time scenarios that happened in industries during the tenure of two or three decades ago. These articles will help you to improve your troubleshooting skills and knowledge.
Author RCA queries, answers are
Q- Why compressors’ < 40% only availabilities even after eliminating drive problems
A-Too poor-quality valves of listed below defects:
Q- How to improve?
A- Compressor valves manufacturing Hi-tech task is best left to specialist firms. Hence, the author selected from a well-known Austrian OEM Vendor catalog suitable suction and discharge valves.
Though the vendor offers a custom valve at 20% extra cost, the author selected their standard valve because compressors valve ports bore increases to fit the just 1 mm more body dia Austrian valves is just a one-time negligible cost task.
Below are the savings
Compressor ownership costs neglecting the negligible depreciation costs | 10668698 |
Painting Contractor air cost bill | 31914894 |
Yearly Savings | 21246196 |
Additional expenses – compressor fitted 2 Nos. + 2 reconditioning rotatable Austrian Valves | 70000 |
Payback days | 1.20 |
Hence benefits summary is:
