When one side is performing the suction stroke, the other side will be performing compression & delivery of compressed air. See figure 1,2,3 for the most widely used patterns. 1st compression stage: increase pressure (from 0bar to 7–20 bar, veries based of manufacturer). Single-acting cylinders compress gas in only one direction of piston travel. If you need more, a rotary screw compressor might be a good option. Most reciprocating compressors use double-acting cylinders. d is very small as They are almost universal in ... the lower side of the piston acting as a piston compressor to compress the inlet charge ready for the next stroke. Hence, in case of single reciprocating pump. Reciprocating compressors. These characteristics given their popularity in the refrigeration field. Single Stage air Compressor. bottle blowing industry with the pressure, air flow and cost effective controls required to operate the energy-efficient and reliable systems. connected with piston, A, Discharge Double Acting. The reciprocating compressor is single acting when the compressing is accomplished using only one side of piston and double acting when both the sides of piston used. Applications The reciprocating compressor generally seen where there is requirement of high pressure and low flow(or discontinuous flow up to 30 bars).Mostly where the air is used for hand-tools,cleaning dust,small paint … Number of Plunger in One Casing : Single, Duplex, Triplex, Multiplex 5. In this, the water is acting on both sides of the piston as shown in the figure. https://learnmech.com/reciprocating-compressor-parts-diagram-basic-working If the mechanical energy is converted in to stored For multi stage reciprocating air compressor stages are: Dehumidifier: Reduce moisture content. Diagram of a rotary-screw compressor. Please write in comment of working strokes per minute. The opening & closing of a simple check valve (plate or spring valve) depends upon the difference in pressure, if mechanically operated valves are used for suction & discharge then their functioning is controlled by cams. revolution of crank and water will be discharged through the delivery pipes B. crank will be determined as mentioned below, Discharge of pump in one revolution of the crank will The oil is separated from the discharge stream, cooled, filtered and recycled. Principles on which compressors work: A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. The double-acting reciprocating compressor working principle is very simple. 13. case of double acting reciprocating pump as displayed here in following figure. piston. It is comprised of following parts: 1) Cylinder 2) Piston and piston rod and connecting rod. google_ad_slot = "3099818450"; 1.3. double acting reciprocating compressor system diagram. When the pressure increases upto its design limit it pushes the discharge valve to open and the compressed air is delivered to the storage tank. Simple steps compressor is designed so vapor compression occurs only on one side of the piston. Crosshead assembly is composed of crosshead slide guide and crosshead. Now that we have seen the principle of working of the reciprocating compressor, let us see the various parts of the compressor. The cylinder is in communication with suction and delivery pipes. Choice of cylinder material is determined by operating pressure. Multi-staging:Reduction in power required to drive the compressor. 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. 1.3 Objectives The project is set out to achieve a few objectives which are listed as follows: To identify the unbalanced forces of the reciprocating compressor.
