LAITE HÖYRYLUKKOJEN TOIMINNAN HAVAINNOIMISEKSIDEVICE FOR DETECTING THE OPERATION OF STEAM LOCKS
Keksinnön kohteena on laite höyrylukkojen toiminnan havainnoimiseksi. Sen avulla voidaan valvoa 5 höyrylukkoa, so määrittää ja/tai mitata erityisesti höyryvuotoja.The invention relates to a device for detecting the operation of steam locks. It can be used to monitor 5 steam locks, i.e. to determine and / or measure steam leaks in particular.
Höyrylukko asennetaan höyrylinjoihin tai höyryä käyttävään laitteeseen ja se mahdollistaa kerääntyneen veden automaattisen poiston ilman höyryvuotoa.The steam trap is installed on steam lines or a steam-powered appliance and allows the automatic removal of accumulated water without steam leakage.
10 Polttoaineiden hinnan noususta johtuen nykyisin kohdistetaan yhä suurempia vaatimuksia höyryvuotojen tarkkailuun. Höyryvuotojen ehkäisystä on tullut ehto höyry-lukkojen käytölle. Asennuksen jälkeen höyryputkistoja valvotaan tarkasti ja höyryä vuotava höyrylukko korja-15 taan tai korvataan uudella välittömästi.10 Due to rising fuel prices, there are now increasing demands for monitoring steam leaks. Prevention of steam leaks has become a condition for the use of steam locks. After installation, the steam piping is closely monitored and the steam-leaking steam lock is repaired or replaced immediately.
On kehitetty ja on olemassa käytössä eri tyyppisiä höyrylukon vuodon ilmaisimia. Esimerkiksi käytetään ikkunaa putkistossa höyrylukon ulostulopuolella mahdollistamaan sisäpuolisen virtauksen tilan visuaali-20 nen tarkastelu ja myös käytetään lämpötila-antureita ja värinäantureita mittaamaan höyrylukon pintalämpötilaa ja lukon läpi virtaavan virtauksen aiheuttamaa ääntä.Different types of steam lock leak detectors have been developed and are in use. For example, a window in the piping on the outlet side of the steam trap is used to allow a visual inspection of the internal flow state, and temperature and vibration sensors are also used to measure the surface temperature of the steam trap and the sound caused by the flow through the lock.
Molemmissa tapauksissa höyrylukon vuodon tila määrätään vain kvalitatiivisesti ja kvantitatiivista 25 mittausta ei voida suorittaa. Tämän vuoksi vuodon määrän arviointi on riippuvainen käyttäjän asiantuntemuksesta .In both cases, the leakage state of the steam trap is determined only qualitatively and a quantitative measurement cannot be performed. Therefore, the assessment of the amount of leakage depends on the expertise of the user.
Japanilaisesta patenttihakemuksesta nro 61-57499 tunnettu ilmaisin sallii höyryvuotojen määrit-30 tämisen, samalla kun värähtelyt ja mitatut höyryvuodot asetetaan suhteeseen keskenään; parametrina värähtelyille käytetään höyrynpainetta, ja höyryvuodot määritetään ilmaisimen välityksellä, johon kuuluu lämpötila-ja värähtelyanturi ja on sijoitettu höyrylukon rungon 35 ulkopinnalle.The detector known from Japanese Patent Application No. 61-57499 allows the determination of steam leaks while setting the vibrations and the measured steam leaks in relation to each other; the vapor pressure is used for the parameter vibrations, and the steam leaks are determined by a detector including a temperature and vibration sensor and located on the outer surface of the steam lock body 35.
Japanilaisesta patenttihakemuksesta nro 61-56521 entuudestaan tunnettu laite on sijoitettu 86765 2 höyrylähteen pään ja höyrylukon väliin. Höyryvuodon määrittämiseksi aukon läpi virtaava höyrymäärä määritetään suhteessa tulopuolen veden pinnan tasoon. Tämä tunnettu laite soveltuu tosin höyrylukon toiminnan ha-5 vainnoimiseen, mutta kuitenkin monimutkaiset manuaaliset toimenpiteet ovat tarpeen toiminnan havainnoimisen ja vuotomittauksen tulosten hyväksikäyttämiseksi sekä vuotojen summaamisen, yhteenvetämisen ja ratkaisemisen kustannus- tai hylkyprosenttitermien muodossa valmisteli) lemiseksi. Sitäpaitsi epätiiviin höyrylukon korjaukseen tai vaihtoon voidaan ryhtyä vasta ratkaisun jälkeen, mikä ei salli höyrylukon optimaalista huoltoa.A device previously known from Japanese Patent Application No. 61-56521 is located between the head of a steam source 86765 2 and a steam lock. determining the steam leakage flow through the orifice is determined by the amount of steam relative to the plane of the inlet-side surface of the water. Although this known device is suitable for detecting the operation of a steam trap, complex manual operations are necessary to exploit the results of operation detection and leakage measurement and to prepare the summation, summary and resolution of leaks in the form of cost or scrap percentage terms. In addition, leaking or replacing the leaking steam lock can only be carried out after the solution, which does not allow optimal maintenance of the steam lock.
Keksinnön tarkoituksena on tuoda esiin yksinkertainen höyryvuodonilmaisin sekä koottujen tietojen 15 automaattisen yhteenvedon ja ratkaisemisen mahdollistaminen ja korjausten tai vaihdon ennustaminen.The object of the invention is to provide a simple steam leak detector as well as to enable the automatic summary and resolution of the collected data 15 and to predict corrections or exchanges.
Tämän ongelman ratkaisemiseksi keksinnön mukaiselle laitteelle on tunnusomaista se, mitä on esitetty patenttivaatimuksessa 1.To solve this problem, the device according to the invention is characterized by what is stated in claim 1.
20 Keksinnön mukaisesti laitteeseen kuuluu toi mintatapaa tarkkaileva sekä kunkin höyrylukon höyry-vuotoja mittaava ja tallentava höyryvuotoilmaisin ja tallennetuilla tiedoilla syötettävä isäntätietokone, joka on järjestetty rekisteröimään ja näyttämään kaik-25 kien höyryvuotojen summan ja vuotojen yhteenvedon sekä analyysin kustannus- ja/tai hylkyprosenttimuodossa, ja näyttämään ennaltamääritettynä höyrylukon vaihtamis-ajankohdan. Kunkin höyrylukon toiminnan tarkastelu ja höyryvuodon mittaus suoritetaan höyrynvuotoilmaisimel-30 la. Tämän toiminnan analyysin ja vuodon mittauksen tulokset rekisteröidään höyrynvuotoilmaisimen rekiste-röintiosaan ja kaikkien höyrylukkojen tarkastuksen jälkeen rekisteröity data siirretään isäntätietokoneeseen .According to the invention, the apparatus comprises a method of monitoring the operation and measuring and recording the steam leaks of each steam lock and a host computer input with the stored data, arranged to register and display a sum of all steam leaks and a summary and analysis of costs and / or costs. predetermined the time of changing the steam lock. An examination of the operation of each steam lock and a measurement of the steam leakage is performed by a steam leak detector-30 la. The results of the analysis of this operation and the measurement of the leakage are registered in the registration section of the steam leak detector, and after checking all the steam locks, the registered data is transferred to the host computer.
35 Isäntätietokone rekisteröi ja esittää lopputu loksen kunkin höyrylukon toiminnan tarkastelusta ja vuodosta, tarvittavan yhteenvedon ja analyysin jokaisen 3 86765 lukon kokonaisvuodosta ja vuodon kustannusten ja pois-tomäärän perusteella sekä vaihtamisajankohdan ennalta kullekin höyrylukolle.35 The host computer records and presents the final result of the inspection and leakage of each steam lock, the necessary summary and analysis of the total leakage of each 3 86765 locks and the cost and removal rate of the leak, and the time of replacement in advance for each steam lock.
Tällä tavoin voidaan tarkastusten tulosten 5 yhteenveto ja analysointi suorittaa automaattisesti ja oikein ja vastaavasti suorittaa höyrylukkojen valvonta tai ylläpito yksinkertaisemmin ja tehokkaammin. Lisäksi, koska vuotomäärien muutokset rekisteröidään ja esitetään, niin samalla korjauksen tai vaihdon ajankohta 10 voidaan automaattisesti määrätä määräämällä tämä ajankohta ennalta vuotomäärien perusteella.In this way, the summary and analysis of the results of the inspections 5 can be performed automatically and correctly and, accordingly, the monitoring or maintenance of the steam locks can be performed more simply and efficiently. In addition, since changes in leakage rates are recorded and displayed, at the same time, the time of repair or replacement 10 can be automatically determined by predetermining this time based on the leakage rates.
Tietokoneelle tapahtuvaa manuaalista tietojen syöttöä voidaan välttää lukemalla viivakoodilukijalla kunkin höyrylukon numero ja tyyppi kunkin lukon ollessa 15 varustettuna viivakoodilla.Manual data entry to a computer can be avoided by reading with a barcode reader the number and type of each steam lock with each lock having a barcode.
Koska tarkastusten tulokset automaattisesti rekisteröidään, kootaan yhteen ja tulostetaan isäntätietokoneen avulla, manuaalista työtä voidaan vähentää mahdollistaen työn säästön ja standardisoinnin.Because inspection results are automatically recorded, compiled, and printed using a host computer, manual work can be reduced, allowing work to be saved and standardized.
20 Lisäksi, koska höyrylukoissa tapahtuvat höyry- vuotojen muutokset ajan funktiona rekisteröidään ja esitetään, vialliset osat voidaan löytää ja korjata tai korvata uusilla hyvissä ajoin, jolloin voidaan estää tuotantokustannusten tuhlaus ja parantaa energiansääs-25 töä.20 In addition, because changes in steam leaks in steam traps as a function of time are recorded and displayed, defective parts can be found and repaired or replaced in good time, thus preventing wastage of production costs and improving energy savings.
