- So negative pressure difference<\/strong> is required to open the valve and called as intake depression<\/strong>.<\/li>\r\n
- Similar situation occurs at 2, at the beginning of delivery stroke. Compressed air is delivered into receiver and hence external delivery pressure is also known as receiver pressure.<\/strong><\/li>\r\n
- Gas inertia and turbulence also affecting the inlet and delivery.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n

- \r\n
- Inertia and friction effects, which results in valve flattering and increase the area of diagram slightly and hence their effects is to increase the total work of compression.<\/li>\r\n
- LP and HP diagram overlap due to pressure drop in intercooler.<\/li>\r\n
- Wavy lines during induction and delivery strokes are due to \u201cFlatter\u201d of valve\u2019s disc.<\/li>\r\n<\/ul>\r\n

- \r\n
- Greater vibration problem.<\/li>\r\n
- Mechanical efficiency is lower compare to rotary compressor because of several sliding and bearing members.<\/li>\r\n
- Pressure ratio per state is 5 to 8<\/strong>.<\/li>\r\n
- Delivery volume is small (250 \u2013 300 m3<\/sup>\/min) compared to rotary compressor (2000 \u2013 3000 m3<\/sup>\/min).<\/li>\r\n
- Compression efficiency is high at compression ratio above 2.<\/li>\r\n
- Reciprocating air compressors<\/strong> are having isothermal compression<\/strong> where as Rotary air compressors<\/strong> are having isentropic compression<\/strong>.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
