Title:
MAINTENANCE MANAGING DEVICE FOR VALVE
Document Type and Number:
Japanese Patent JP3463155
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To exactly predict an optimum timing by converting the leaked quantity data of valve into a lost amount of money, storing it, performing the regression processing of this lost amount of money, comparing the predicted amount of money with the cost of repair and exchange and predicting the timing of repair and exchange.
SOLUTION: A leaked quantity detector 2 detects the leaked quantity of steam by detecting a vibration level with the operation of a steam trap 1 and a microporocessor 3 converts these leaked quantity data of steam into the lost amount of money by multiplying the leaked quantity data by a unit steam price at a converting means 4 and stores the converted lost amount of money in a storage means 5 for every data and time of detection. The regression processing of this stored lost amount of money is performed by linear regression analysis or quadratic curve regression analysis, and the regression curve is displayed on a display means 7. On the other hand, when the cost required for repairing and exchanging the stream trap 1 is inputted from an input means 6, the microprocessor 3 finds the timing of repair and exchange from the lost amount of money matched with the cost of repair and exchange on the regression curve and displays that timing on the display means 7.
