A Study of Flapper Valve Motion in a Variable Speed Compressor
نویسندگان
چکیده
This study is an attempt to determine if there is any speed sensitive phenomenon in flapper valve operation. Valve motion is measured at various speeds in a reciprocating residential refrigerator/freezer compressor. Laser Doppler Velocimetry is used to measure the velocity of a point on the flapper at the center of the port for the suction valve. This velocity data is numerically integrated to produce displacement as a function of crank angle for each speed. An attempt is made to correlate compressor speed with any behavior that might either improve compressor performance or, conversely, decrease valve life.

متن کاملModulus of Elasticity and Its Influence on the Performance of Flapper Valve Materials
Modulus of elasticity of flapper valve material is an important parameter for compressor design since it can affect efficiency and life time of the compressor. Modulus of elasticity is usually considered as a material constant. Actually, it can vary with material orientations and conditions and even environments such as temperature will also affect this value. Therefore, the parameters that can...
متن کاملVibration Analysis of an Air Compressor Based on a Hypocycloidal Mechanism: an Experimental Study
In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

متن کاملStudy on the Fatigue Strength of a Suction Flapper Valve Used in a High Efficient Reciprocating Compressor
Suction valves with even thinner and narrower, used in a high efficient reciprocating compressor, are required in order to reduce suction resistances. However, low flow resistance suction valves run properly under the very severe operating condition of high periodic impact stress which can cause the compressor failure. In this study, the effects of the valve design parameters on the impact fati...
