Reciprocating Compressor Application and Selection Criteria Use only this equation for finding out the dimensions of the cylinder. It means the cylinder consists of two suction valves and two delivery valves. Reciprocating Piston Parts. The purpose of the performance testing is to verify the theoretical calculations with the practical performance. Reciprocating Compressor . When the piston is compressing the gas on one side, the gas is sucked into the cylinder on the other side of the piston. In single-acting machines the compression takes place on only one side of the piston; double-acting machines use both sides of the . Above equation is the equation for the discharge of the double acting reciprocating pump. Gas is compressed by only one end of the piston. This hole is filtered with the stuffing box or gland to prevent flit of working . Compressors have cyclic loads. 1. It helps in providing efficient compression as compared to the single-acting one. The loads (forces) that are generally of concern include the piston rod loads, the connecting rod loads the crosshead pin loads, the crankpin loads, and the frame loads. This gives you two compression cycles for every turn of the crankshaft. Cast iron is normally used for pressures up to 1,000 psi. Reciprocating compressors and reciprocating pumps are mainly used to produce a high discharge pressure that is either difficult or uneconomical for the centrifugal machineries or other types of machineries to achieve. Single-Stage Reciprocating Compressor Compression is done in single stage or by single cylinder only and it is used for generation of low pressure air. Double-Acting Reciprocating Compressor. The clearance volume is 10 cm3. So, the double-acting air compressor has four valves (2 outlets and 2 inlet valves), as shown in the above-given diagram. With the higher pressures and air flows that are required, the P.E.T. Single acting reciprocating compressor and double acting reciprocating compressor. 1. These compressors are ruggedly . On the one side, there is suction and compression takes place on the other side. In a single-stage compressor, the air is compressed one time; in a two-stage compressor, the air is compressed twice for double the pressure. A single stage double acting air compressor of 150KW power takes air in at 16 bar & delivers at 6 bar. Work done by double acting reciprocating pump Work done per second = Weight of water delivered x total height The law of compression in both the stages is pV 1.3 = constant.

This ring set consists of two tangent rings pinned to each other packing rings) 'n=1 for single acting compressor, 'n=2 for double acting compressor . In single stage reciprocating air compressor the compression of the air takes place in a single cylinder. In a reciprocating compressor, a volume of air is drawn into a cylinder, it is trapped, and compressed by piston and then discharged into the discharge line. if in forwarding stroke suction is . Consequently, it reduces the . This reciprocating compressor is given because it uses both sides of the piston to compress the air. Double‐Acting,Water‐Cooled Reciprocating Air Compressors Advantages include: • Efficient compression, particularly with multi‐stage compressors • Three‐step (0‐50‐100 percent) or five‐step (0‐25‐50‐ 75‐100 percent) capacity controls, allowing efficient part‐load operation A benefit of double-acting reciprocating compressors is the reduction of cyclic peaks, such as the force acting on the connecting rod. The double acting compressor compresses the air on both the up-stroke and the down-stroke of the piston, doubling the capacity of a given cylinder size. . In the first stroke, it sucks the air from the atmosphere and in the second stroke it compresses it and deliver it to the storage tank. Single - Acting compressor: It is a reciprocating compressor that has one discharge per revolution of the crankshaft. Changed From Double to Single-Acting Unit: • Four throw reciprocating compressor. 08042538600 88% Response Rate. I. The single-stage .
