Abstract
Kompresori su strojevi koji komprimiraju neki plin na viši tlak odnosno podižu mu energetsku vrijednost. Takav zrak koristi se za uputu u rad brodskih dizelskih motora. Najčešće na brodovima za uputu dizelskih motora u rad upotrebljavaju se dvostupanjski stapni kompresori. Termodinamički gledano razlikujemo politropsku, izentropsku i izotermnu kompresiju. Višestupanjska kompresija daje uštedu na radu, i što kompresor ima više stupnjeva, to je bliži izotermnoj kompresiji. Višestupanjski... More kompresori zagrijavaju plin (zrak) za vrijeme tlačenja, što može dovesti do eksplozije para mazivog ulja pomiješanih sa zrakom. Da se izvrši tlačenje do visokih tlakova, i izbjegne zagrijavanje i opasnost od eksplozije para ulja i zraka izvodi se višestupanjsko tlačenje s međustupanjskim hlađenjem. Kompresori na brodu uglavnom se pogone elektromotorom. Treba voditi računa o tome da se pri upućivanju do pune brzine vrtnje elektromotor ne preoptereti. Kompresor i sve njegove komponente moraju se redovito pregledavati u intervalima koji ovise o nekoliko radnih uvjeta. Danas se na brodovima koristi automatska izvedba dobave uputnog zraka za pokretanje dizelskih motora. Less
Abstract (english)
Compressors are machines which compresses gas on to higher value of pressure respectively they raise its energetic value. That is sort of compressed air that is used to put marine diesel engine into work. The most used sort of the compressors on ships are two-stage reciprocating compressors. From thermodynamics of compression we look at polytropic process, isothermal process and isentropic process. Multistage compression is used to save power and for higher stage of compression,... More compressor is closer to isothermal compression. Multistage compressor heats air in compression process, which can lead to explosion of the steam of lubricating oil mixed with air. To compress air to high pressures and to avoid overheating and danger of explosion it is used multistage compression with intermediate stage cooling. Compressors on ships are mostly driven by electromotors. It should be taken into account that during going in to full speed we don’t overload electromotor. Compressor and all his components are needed to maintain regularly in periods which depends on several working conditions. In today modern days compressors in start air system are automatically regulated Less
