What reading level is Pumping Machinery: a Practical Hand-Book Relating to the Construction And ... book?
To quickly assess the difficulty of the text, read a short excerpt:
If the metal chosen be phosphor-bronze, it will add but little to the cost, and a much stiffer casting will be secured.
Double-Acting Pressure-Pump.— The sectional eleva- tion shown in Fig. 129 represents the usual design for a small pressure-pump; it shows an objectionable detail in a neces- sity for putting the largest valves on the delivery side of the pump, where they are not needed, instead of the suction side, where they are needed. This fact does not prevent the pump doing good work, and... is not considered as absolutely bad. The valve-seats are usually fitted and driven tightly into straight holes, from which they may be removed whenever desired by means of a hook bolt-head underneath the bush- ing, with a strap and nut above. The diameter of the upper valve-seat must be large enough to permit the passage of the lower valve through it. The valves and seats are usually of hard gun-metal or phosphor-bronze. The caps over the valves are also of gun-metal or hard brass. For small pumps no objection exists to tapping the water-end for insertion of the caps as shown, but for larger pumps, say those having plungers of 3 inches diameter and larger, square or round caps, held in place by bolts and nuts, are to be preferred.
