Ang Gao . Experimental Procedure. [7] The system can give real-time process monitoring on test data and compile test reports of the reciprocating two stages compressor. The piston is attached to the crankshaft with the help of a connecting rod and thus the rotation of the crankshaft causes the piston to move up and down inside the cylinder. Das: Investigation on the failure of air compressor. In the beginning of the experiment, air is drawn into the compressor through a filter and compressed in the first stage with a low pressure cylinder that reduce the volume and increase the temperature of the air. [8] The reciprocating air compressor is single acting when the compressing is accomplished using only one side of the piston.

S. Sivaprasad, N. Narasaiah, S.K. The piston compressor, also denoted reciprocating, is a displacement compressor type which consists of a moving piston which compresses the air. It’s a legacy of creating new standards for how the world gets work done. Watch Queue Queue. The crankshaft is mounted on the crank case. For the delivery pressures of 1 bar, 2 bar, 3 bar, 4 bar and 5 bar, the readings from the corresponding VDAS were recorded as shown in table 1, A compressor uses a moving piston to compress a system of fixed mass of air to a point where a desirable system’s pressure is reached before letting air out through the air receiver. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time. Compressor Control 7 IX. https://doi.org/10.4028/www.scientific.net/AMR.230-232.1269. The noise produced by the electric motor which drives the compressor is reduced by a soundproof housing.

Experimental Investigation on Reciprocating Air Compressor Performance. Reciprocating Compressors and Its types This type of compressor uses piston-cylinder arrangement to compress the air.Whenever something moves back and forth … Within a refrigerator, a compressor potentially increases the pressure and consequently increases the boiling point or saturation temperatures of the vapor to allow the refrigerant to condense by losing its heat to the condenser (AlThobiani & Ball, 2014). [3] A compressor is a device that has a potential of converting power from a chemical energy into potential energy in the form of pressurized air mass that is normally applied in refrigeration purposes (Bin et al., 2013). The design and main functions of the automatic acquisition and testing system for air compressor performance was introduced. ethylene glycol. After the engine is running for a sufficient time (approx. A reciprocating stroke compressor is a type of air compressor that compresses the air in a cylinder by transferring it upward at the top dead center (TDC) and the suction of the external air when moving it downward at the bottom dead center (BDC) of the cylinder, as illustrated in Fig. A reciprocating compressor is a positive displacement machine in that a volume of gas is drawn into a compressor cylinder’s compression chamber where it is trapped, compressed and pushed out. Purpose 2 II. The compressor was set at a speed of 100 revolutions per minute with its delivery bulb open after which the corresponding load and power were recorded under no load situation. Main Component of Reciprocating Compressor 3 V. Operating Range of Reciprocating Compressor 4 VI. 2(a). Expressions for the volumetric effectiveness, the work per unit mass and the indicated efficiency are derived. RECIPROCATING COMPRESSOR TABLE OF CONTENT I. [6] This compressor includes two sets of concentric annular fins with different diameters: the mobile fins are pushed into the space between the stationary fins through a driver shaft and compress the air trapped in the interconnecting annular chambers while keeping the air temperature close to ambient. PROCEDURE The compressor used in this experiment is an Integersol-Rand type 30 two-stage air compressor. In this experiment, the air compressor used was two stage reciprocating piston type and the speed of the motor is adjusted from low flowrate from 885 to 1377 rotation per minute. The model is based on five main and four secondary dimensionless physically meaningful parameters. Read here to know about the basics of compressing air and appreciate the reason for air compressor following polytropic or isentropic compression instead of isothermal or adiabatic one. The values were then entered into a VDAS screen display. Compressed air is stored in the air receiver.
