In a Double-Acting Reciprocating compressor, air is compressed as the piston moves in each direction. The screen is attached to the outside of the strainer basket so that the flow encounters the screen first. A double-acting compressor with c= 7% draws 40 lb per minute of air at 14.7 psia and 80F and discharges it at 90 psia. Single Stage air Compressor A double acting cylinder alternates cycles of pressurized fluid to both sides of the piston and creates extend and retract forces to move the piston rod, permitting more control over the movement. On double-acting, large compressors the L type with vertical low-pressure cylinder and horizontal high-pressure cylinder, offer immense benefits and is why this the most common design. Parts Of Reciprocating Compressors : Piston type compressor consists of . if in forwarding stroke suction is taking place on one side then expansion is taking place on the . Gas is compressed by both the ends of the piston. This technology in only used in heavy duty industrial and process. Download files Like. Double acting compressors. A double acting compressor is one that both the top and the bottom of the cylinder do compressing. In a single-stage, the air is compressed one time; in a two-stage, it is compressed twice for double the pressure. A double-acting reciprocating compressor is a cylinder where working fluids work on both sides of the piston. But it is still considered a single stage compressor. We have now our very own manufacturing facility and sourcing place of work. Double - Acting Compressor: It is a reciprocating compressor that completes two discharge strokes per revolutions of the crankshaft. Double - Acting Compressor - It is a compressor that completes two discharge strokes per revolutions of crankshaft. On double-acting, large compressors the L-configuration with a vertical low pressure cylinder and horizontal high pressure cylinder offers immense benefits and has become the most common design. A detailed explanation on the all these variants can be found at the next part of this guide; Types of Reciprocating Compressors.

In order to double the capacity of a given cylinder size, the double acting compressor compresses the air on both the up-stroke and the down-stroke of the piston. r] (mechanical engineering) A reciprocating compressor in which both ends of the piston act in working chambers to compress the fluid. Single & Multistage Compressor When suction and discharge is from only one cylinder , then it is single stage compressor. In these types of compressors, an "automotive-type" piston driven by a crankshaft provides the compression. Rapid switching from full load to half load and back again ensures a flexible response to compressed air demand and a low-pressure difference in the network. While at the same time discharge stroke is in process at another end of the piston. Find (a) the work, (b) the heat rejected, (c)the bore and stroke for 90 rpm and L/D= 1.25. Most reciprocating compressors use double-acting cylinders.
