Kudzivirirwa Kuputika muIndasitiri otomatiki: Kutungamira Kuchengetedzeka Pamusoro pePurofiti
Kudzivirirwa kwekuputika hakungori chinodikanwa chekuteedzera-ndiyo musimboti wekuchengetedza. Sezvo maChinese anogadzira otomatiki anowedzera kuita maindasitiri ane njodzi zvakanyanya senge petrochemicals, migodhi, uye simba, kunzwisisa kuputika kwemazinga ekudzivirira kunova kwakakosha kune ese ari maviri emakwikwi epasirese uye kuchengetedza kushanda.
Iyo Sainzi Kuseri Kwemaindasitiri Kuputika
Kuputika kunoda zvinhu zvitatu zvakakosha:
- Chinhu chinoputika- Magasi (hydrogen, methane), zvinwiwa (doro, peturu), kana guruva (shuga, simbi, hupfu)
- Oxidizer- Kazhinji oxygen iripo mumhepo
- Ignition Source- Sparks, nzvimbo dzinopisa, static discharge, kana kemikari kuita
Nheyo inokosha yekudzivirira kuputika inosanganisira kubvisa chimwe chezvinhu zvitatu izvi.
Kunzwisisa Kuputika-Chiratidzo Chekushandisa Makaka: "Ex ed IIC T6"
Uku kucherechedzwa kwakajairwa pamidziyo inodzivirira kuputika kunoratidza:
- Ex: Kutevedzera mitemo yekudzivirira kuputika
- e: Kuwedzera kuchengetedza dhizaini
- d: Flameproof yakavharirwa
- IIC: Inokodzera gasi rine njodzi huru (hydrogen, acetylene)
- T6: Kunyanya tembiricha yepasi ≤85°C (yakachengeteka kune zvinhu zvine nzvimbo dzakaderera dzekudzima)
Yekutanga Kuputika Dziviriro Nzira
Kuvharirwa kweFlameproof (Ex d)
Yakanyatsogadzirirwa kuve nekuputika kwemukati uye kudzivirira kupisa kwekunze kune njodzi mamiriro ekunze.
Intrinsic Safety (Ex i)
Inomisa simba remagetsi kusvika pamazinga ari pasi pezvinodiwa kukonzera kubatidza, kunyangwe panguva yekukanganisa. Inoda zvipingaidzo zvekuzviparadzanisa kuchengetedza kuchengetedza mukati mehurongwa.
Kurongeka kweNzvimbo ine njodzi: Mazoni, Mapoka eGasi & Kuyerwa kweTembiricha
Zone Classification (IEC Standards)
- Zone 0: Kuenderera mberi kuvapo kwemhepo inoputika
- Zone 1: Pamwe kuvapo panguva yakajairika maoparesheni
- Zone 2: Kashoma kana kupfupi kuvapo kwemhepo inoputika
Gasi Group Classification
- IIA: Low ngozi magasi (propane)
- IIB: Medium njodzi magasi (ethylene)
- IIC: High ngozi magasi (acetylene, hydrogen)
Tembiricha Ratings
| T-Kirasi | Maximum Surface Temperature |
|---|---|
| T1 | ≤450°C |
| T6 | ≤85°C |
Nhoroondo Tsaona: Zvidzidzo Mukuchengetedza
- BP Texas Guta (2005): 15 nzufu dzakakonzerwa nekubatidzwa kwehutsi hwehydrocarbon
- Buncefield, UK (2005): Kuputika kukuru kwemafuta-mhepo kunokonzerwa nekuzadza kwetangi
- Imperial Sugar, USA (2008): Kuputika kweguruva kunouraya vanhu gumi nemana nekuda kwekusachengetwa zvakanaka kwemba
Matambudziko aya anosimbisa kukosha kwakakosha kwemasisitimu edziviriro, nzvimbo-yakakodzera kuputika.
Kusarudza Safe Automation Equipment: Mafungiro Akakosha
Paunenge uchisarudza otomatiki mhinduro dzenzvimbo dzine njodzi, gara uchisimbisa:
- Iyo midziyo inoenderana neyako chaiyo nzvimbo uye gasi boka zvinodiwa?
- Tembiricha kirasi yakakodzera application yako?
- Zvese zvikamu chikamu cheyakasimbiswa kuputika-proof system?
Usambofa wakakanganisapamitemo yekudzivirira kuputika. Kuchengeteka kunofanira kunge kuri iko kuri kuita sarudzo dzekugadzira - nekuti izvo zviri mungozi zvinotambanukira kupfuura kudyara kwemari kuhupenyu hwevanhu.
