DBK Series Reciprocating Booster Air Compressors Compressed air is a pneumatic energy source which is as important as electricity and hydraulics in production sector. Especially for the production of the pet bottles which the usage of them is getting higher and higher in daily life, high pressure is a must Besides, the applications such as leak proofing tests of hydraulic and pneumatic devices, specific drive cylinders, presses and fixture apparatus also need high pressure air. Unlike other applications requiring only low pressure air, both low and high pressure levels of air up to 40 bars ought to be used in the facilities for these applications. Therefore, instead of designing whole system considering the high pressure need, increasing the air pressure just at the certain points where high pressure is needed is the most suitable solution. As a manufacturer having reciprocating booster compressors in its product portfolio which boost the 7-13 bar compressed air taken from rotary screw compressors up to 40 bars, DALGAKIRAN provides the most appropriate solutions with its years of experience and quality policy to pet manufacturers and the enterprises which have to use high pressure air. COMPRESSOR BLOCK • Heavy duty cast-iron crankcases contain oil level indicators properly placed on crankcase, blowdown valve and oil filling/draining plugs. • Cast-iron cylinders and bare pumps with cooling fins help the system preventing overheat. • Dynamically balanced and precisely manufactured sphero cast crankshafts and counter weights, which are specially designed in accordance with Lloyd type-approval certification, prolong the lifecycle of • Special design finger-type high capacity and high pressure-resistant inlet-outlet valves made from stainless steel are capable of holding airflow in upper levels as well as operating at high temperatures. • Compression and oil retaining rings are used for holding the airflow maximized and preventing oil MAIN MOTOR AND DRIVE SYSTEM • High efficiency IE2 class IP55 motors working with 380V/3 phase/50Hz power inlet are used as a standard in DBK series compressors. • Driving the crankshaft is realized by a belt-pulley mechanism placed between compressor block and main motor and selected considering a suitable transmission ratio. • Belts are chosen by considering the working life of minimum 25,000 hours • Special design fan type cast-iron pulleys not only provide airflow with large volumes to cool compressor block but also act as a flywheel to damp the vibrations occurred during operation. • With easy adjustment of belt tension, continuously efficient operation of the • Special loadless operation system lengthens the lifecycle of the main motor SAFETY SYSTEMS • Intake air control system • High pressure switch • Manual discharge valve • Non-return valve • Belt-pulley guard • Outlet pressure manometer
