Abstract

The present invention is designed to transmit to a host computer a result of judgement of operation of each steam trap and measurement of steam leakage, to automatically totalize and analyze the result of measurements, and to predict the time to repair or replace.

Description

15 20 25 30 35 sos 414 2 mellan mängden ånga som passerar genom en öppning och en vat- tennivà på primärsidan. 15 20 25 30 35 sos 414 2 between the amount of steam passing through an opening and a water level on the primary side.

Ovannämnda anordning har förmåga att bedöma en ångfällas funktion och mäta ångläckage, men det krävs omfattande manuellt arbete för iordningställande av en lista med resultat över driftsbedömning och läckagemätning och för summeringen av läckage och ge en totalbild och analys av läckage uttryckt i kostnad eller kassationstakt. Dessutom utförs reparation eller utbyte av en fälla, som läcker ånga, efter kontroller och kan följaktligen icke vara positivt underhåll av ångfällorna.The above device has the ability to assess the function of a steam trap and measure steam leakage, but extensive manual work is required to prepare a list of results of operational assessment and leakage measurement and to summarize leakage and provide an overall picture and analysis of leakage expressed in cost or disposal rate. In addition, repair or replacement of a trap that leaks steam is performed after inspections and consequently can not be positive maintenance of the steam traps.

Det tekniska problem som ligger till grund för förelig- gande uppfinning är därför att möjliggöra automatisk total- sammanställning och analys av kontrolldata och förutsägelse av en reparatíons- eller utbytesperiod.The technical problem underlying the present invention is therefore to enable automatic total compilation and analysis of control data and prediction of a repair or replacement period.

För att lösa detta problem åstadkommes i enlighet med föreliggande uppfinning en anordning, varmed varje fällas drift bedöms och ångläckaget mäts och lagras med hjälp av en ångläckagedetektor. Nämnda lagrade data överförs till en värd- dator, som registrerar och presenterar ett resultat av bedöm- ningen av varje fällas drift och läckage, en summering och analys av det totala läckaget vid samtliga.fällor och läckaget uttryckt såsom kostnad eller kassationstakt, och en ändring i varje ångfälla med tiden.To solve this problem, in accordance with the present invention, a device is provided by which the operation of each trap is assessed and the steam leakage is measured and stored by means of a steam leak detector. The stored data is transferred to a host computer, which registers and presents a result of the assessment of each trap's operation and leakage, a summary and analysis of the total leakage at all traps and the leakage expressed as cost or disposal rate, and a change in each steam trap over time.

Funktionen hos ovannämnda tekniska organ kommer att be- skrivas nedan.The function of the above-mentioned technical bodies will be described below.

Bedömningen av varje ångfällas drift och mätningen av ångläckaget genomförs med ångläckagedetektorn. Ett resultat av denna driftsbedömning och läckagemätning lagras först i ång- läckagesdetektorns minnessektion, och efter kontroll av samt- liga ångfällor överförs lagrade data till Värddatorn.The assessment of the operation of each steam trap and the measurement of the steam leakage is carried out with the steam leakage detector. A result of this operational assessment and leakage measurement is first stored in the memory section of the steam leakage detector, and after checking all steam traps, stored data is transferred to the Host Computer.

Värddatorn registrerar och presenterar ett resultat av bedömningen av driften hos och läckaget vid varje ångfälla, den nödvändiga totalsummeringen och analysen av det totala läckaget vid samtliga fällor och läckaget uttryckt såsom kostnad och kassationstakt, och en ändring i läckaget vid varje ångfälla med tiden.The host computer records and presents a result of the assessment of the operation of and the leakage at each steam trap, the necessary total summation and analysis of the total leakage at all traps and the leakage expressed as cost and disposal rate, and a change in the leakage at each steam trap over time.

På detta sätt kan utskrift, totalsummering och analys av resultatet av kontroller genomföras automatiskt och korrekt, och följaktligen kan underhållskontrollen av ångfällorna utföras . vfi._,_f---.__..-,___..._ ._ ...--._-.V,. 10 15 20 25 30 35 505 414 lätt. Eftersom ändringen av läckaget med tiden registreras och presenteras, kan även tidpunkten för reparation eller ut- byte konstateras automatiskt genom bestämning i förväg av tid- punkten för reparation eller utbyte på basis av läckage.In this way, printing, total summation and analysis of the result of inspections can be performed automatically and correctly, and consequently the maintenance inspection of the steam traps can be performed. v fi ._, _ f ---.__..-, ___..._ ._ ... - ._-. V ,. 10 15 20 25 30 35 505 414 easy. Since the change in leakage over time is registered and presented, the time for repair or replacement can also be determined automatically by determining in advance the time for repair or replacement on the basis of leakage.

Manuella operationer för inmatning av data i datorn kan undvikas genom avläsning med en streckkodsläsare av varje ång- fällas nummer och typ, som finns tryckt i streckkod på varje ångfälla.Manual operations for entering data into the computer can be avoided by reading with a bar code reader the number and type of each steam trap, which is printed in bar code on each steam trap.

Den särskilda effekt som uppnås med föreliggande uppfin- ning kommer nu att utvecklas närmare.The particular effect achieved with the present invention will now be further developed.

Eftersom resultatet av kontrollerna automatiskt registre- ras, totalsummeras och skrivs ut av värddatorn, slipper man manuellt arbete, vilket möjliggör arbetsbesparing och standar- disering.Since the results of the checks are automatically registered, totalized and printed by the host computer, manual work is avoided, which enables labor savings and standardization.

Eftersom ändringar i ångläckaget vid àngfällan med tiden registreras och presenteras, kan vidare felaktiga delar hittas och repareras eller utbytas i god tid, vilket kan förhindra misshushållning med produktionskostnader och bidraga till energisparande.Furthermore, since changes in the steam leak at the steam trap are recorded and presented over time, faulty parts can be found and repaired or replaced in good time, which can prevent mismanagement of production costs and contribute to energy saving.

En föredragen utföringsform av föreliggande uppfinning kommer nu att beskrivas såsom ett exempel under hänvisning till bifogade ritning, som har en enda figur.A preferred embodiment of the present invention will now be described as an example with reference to the accompanying drawing, which has a single figure.
