Method of supporting sales and maintenance of steam traps and aggregating system for use in the method

Abstract

Disclosed is a system for supporting sales and maintenance activities of steam traps by a seller of the traps to a customer. The system utilizes an aggregating system which effects a step of inputting stored diagnostic result data and model confirmation result data from a diagnostic device which has diagnosed a working condition of each of a plurality of existing steam traps installed in a customer's plant. Based on the diagnostic result data, a first total steam loss amount due to malfunction of steam traps is calculated, the first total steam loss amount comprising aggregation of steam leak amounts of all the existing steam traps. Based on the model confirmation result data, a second total steam loss amount is calculated, which comprises aggregation of differences between inherent steam leak amounts of the existing steam traps under their normal working conditions and inherent steam leak amounts of recommended steam traps under their normal working conditions. A monetary conversion value of an integrated value of a sum of the first total steam loss amount and the second total steam loss amount integrated for a predetermined period is calculated. Comparison data is generated allowing comparison between the monetary converted value and a replacement cost required for lump-sum replacement of all the existing steam traps by the recommended steam traps. The comparison data is outputted for presentation to the customer in sales and/or maintenance activities of the recommended steam traps.
