12 Effect of k on volumetric efficiency. The clearance is high, for illustrative purposes. 11 illustrates the effect of clearance at moderate- and high-compression-ratio conditions. A p–V diagram for a ratio of 7 is superimposed on a diagram for a ratio of 4, all else being the same. A relatively high clearance value (14%) is used for illustrative purposes. The clearance for any commercial compressor designed for a ratio of 7 would be much less than 14%. 12 illustrates the effect of k on volumetric efficiency.
38) can be altered to obtain total theoretical power by multiplying the first term by the number of stages s and dividing the exponent of r by s. The compression ratio r must be the total ratio. However, since compression ratios seldom are equal and perfect intercooling is seldom attained, it is believed that the best general method of figuring is to use one stage at a time. 25 VOLUME REFERENCES Since the most generally required quantities are original inlet volume and inlet volume to subsequent stages (both on a per-minute basis), a summary of equations follows in which the word dry means that there is no water vapor in the quantity of gas or gas mixture involved.
Oil passages are drilled to permit oil flow from the journals to the crankpins. The intersections of these holes must be radiused and polished to prevent stress concentration points. Separate bolted-on or integral counterweights are used to help offset unbalanced forces and moments (Figs. 13). 14 Force-feed lubrication system for reciprocating compressor. 2 BEARINGS AND LUBRICATION SYSTEMS Most units have replaceable precision-bored sleeve-type aluminum alloy crankpin and main bearings. No field fitup or adjustment is necessary.
