Reciprocating Air Microcompressor

چکیده
This paper presents a reciprocating air microcompressor with a piston diameter of 1 mm. A microcompressor construction is proposed aiming at simple fabrication with lots of space for installing inlet and outlet ports. The inlet port of the microcompressor does not have a moving valve, while the outlet port is equipped with a miniature reed valve. The compression process was numerically modelled, considering the flow resistance across the inlet and outlet ports, and the leakage through the clearance between the piston and cylinder. The microcompressor was designed based on the numerical simulation. A stainless steel cylinder was fabricated with a wirecut electric spark machine. A needle of a commercial rolling contact bearing was used for the piston. The microcompressor is equipped with a polyethylene film reed valve. A maximum discharge pressure of 80 kPa (gage, 0.82 kgf/cm 2 ) was obtained at a frequency of 100 Hz,

Performance Improvement of a Reciprocating Air Microcompressor
A previously developed reciprocating air microcompressor having a 1-mm(0.04 in)-diameter piston, an inlet port that did not have a moving valve, and an outlet port equipped with a miniature reed valve, was capable of a maximum discharge pressure of 80 kPa (gage, 11.6 psig) at a piston frequency of 100 Hz. We have improved on this compressor performance, and have attained a maximum discharge pre...
