Open And Closed Types Of Compressors
Compressors are further classified as openness, hermetic or semi-hermetic device. Open the engine compressors and compressor in the form of separate components. These compressors are made of castings and bolts with gasket in the form of a tight seal. Cardan shaft outputs side of the die compressor's crankcase through a seal that prevents the refrigerant and oil escaping from moisture and air from entering the system. The rotational energy from the compressor motor is transmitted to die compressor with belts and pulleys transmission system or gear drives. Open-type compressors are used more chladone-piston applications and all the ammonia refrigerant system.
Hermetic compressors have electric drive and compressor unit sealed in nonrepayable steel case (can). Compressor is connected directly to the engine shaft. All small and medium power with the refrigerant freon compressors sealed design. Semi-hermetic compressors are built of castings, which are joined using strip as a hermetic seal. Motor drive is enclosed in a sealed Carter, so no external shafts or seal is not required. Semi-hermetic compressors types are used halocarbons with refrigerants in middle and high performance applications. Hermetic and semi-hermetic compressors are also called concluded compressors, because they have not revealed the propeller shaft and seals.
