The manner of connecting and valving emptying pipes can be seen in Figs. 95 and 96. PUMPS LIFT OR SUCTION PUMPS Principles of Operation--The operation of a suction pump is dependent on and its efficiency limited by atmos-pheric pressure. If there were no atmospheric pressure there could be no suction lift to a pump. This is shown by a reference to the suction pump, Fig. 97, which consists of a piston,, in a pump barrel or cylinder, b, a valve, c, that opens on the down stroke of the piston Distributing Main--A pipe extending from distributing manifold to a group of fixtures or to a number of groups. t Distributing Branch--A pipe extending from a distributing main to the several fixtures in a group. X Fixture Branch--A pipe connecting a distributing branch to fixture, cock or faucet. and closes on the up stroke, and a valve, d, that opens on the up stroke of the piston and closes on the down stroke. The operation of the pump is as follows: When the piston, a, makes an up stroke it exhausts some air from the suction pipe, e, and a sufficient quantity of water flows in to replace the exhausted air and balance the atmospheric pressure on the water outside. On the down stroke of the piston the exhausted air which has been confined in the pump cylinder escapes through the valve, c, which opens on the down stroke. The next up stroke of the piston still further exhausts air from the suction pipe and a still higher column of water flows in to replace the exhausted air. Repeated strokes of the piston exhaust all air from the suction pipe and pump cylinder, which then fill with water which is pumped out as was the air. Lift of a Pump--Theoret...
