Abstract

Ovim radom prikazana je problematika rada održavanja opreme u prostorima ugroženim eksplozivnom atmosferom, na primjeru opreme firme Biotron d.o.o. – pogon Ozalj. Tehnološkim napretkom i razvojem, mnoga postrojenja rade u uvjetima gdje se mogu pojaviti zapaljive tvari u obliku plina, pare ili prašine, zbog čega je potrebno ugraditi odgovarajuću protueksplozijsku opremu. U radu je zbog boljeg razumijevanja također objašnjena terminologija područja protueksplozivne zaštite te dan sažet uvid u problematiku ovog područja. Klasifikacija prostora ugroženog eksplozivnom atmosferom obrađena je normom HRN EN 60079-10 (1 – za eksplozivne plinove i pare, 2 – za eksplozivnu prašinu) a opisan je pregled osnovnih čimbenika požara i eksplozije. Pošto se najčešće može utjecati samo na pojavu uzročnika paljenja u ugroženom prostoru, kreirano je više vrsta i načina zaštite od pojave eksplozije ili požara. Tako je električna oprema primjer područja gdje postoji najviše raznovrsnih oblika protueksplozivne zaštite. Najčešćim metodama pregleda opreme, dan je informativni prikaz načina i mogućnosti praćenja rada pojedinačnih elemenata pogona i opreme ali i cjelokupnog postrojenja. Pregledom opreme pogona Biotron d.o.o. izabrani su specifični uređaji za koje je dan plan pregleda opreme, te je sukladno tome odabran primjeren način održavanja. U prilogu je dana tehnička dokumentacija prethodno odabranih uređaja pogona Biotron d.o.o. uz obrasce za plan pregleda opreme, kao i obrasci za izvještaj o provedenom pregledu. Iako svaki uređaj ima svoje posebnosti, prilikom vizualnog i kontrolnog pregleda pokušava se utvrditi opće stanje uređaja za što se često koriste unificirani obrasci.

Abstract (english)

This work deals with equipment maintenance in explosion hazardous atmosphere, based on the equipment of the company Biotron d.o.o. – a factory placed in Ozalj. With technological advancement and breakthrough, many factories work in an environment that has possible presence of explosive materials in the form of gas, vapor or dust, which is why there is a need to install adequate explosion-proof equipment. For better understanding the terminology of the explosion-proof field is explained and given a short overview of this area. Classification of explosion hazardous areas is given in HRN EN 60079-10 (1 – for explosive gas and vapor, 2 – for explosive dust) and contains an overview of basic factors which cause fire and explosion. Since, one can only affect the ignition source in hazardous areas, several methods of protection against explosion or fire were developed. Electrical equipment is a fine example where the most explosion-proof methods have already been developed. Diverse methods and principles of inspection are given with most common methods of equipment inspection, whether it's dealing with a single piece of equipment or an entire factory. Few specific devices are chosen from the equipment review list of Biotron d.o.o. factory, where there has been given an appropriate method of maintenance for each element. Technical documentation of previously selected equipment from Biotron d.o.o. factory can be seen in the attachment, as well as inspection report forms. Although, each device has it's own characteristics, visual and control inspection determine the general condition of each equipment, for which unified forms are being used.
