Pulsometers

Devices which are used for transporting fluids (liquids and gases) may be divided into pumps, ejectors, injectors, elevators, conveyors, air and gas pressure devices (such as acid eggs, air lifts, pulsometers etc). Pumps may be divided into piston (reciprocating), centrifugal, propeller, rotary-displacement, density, impact and momentum and turbine pumps. Pumps which...

First of all liquid chlorine is measured in a pulsometer, then collected in a liquid chlorine receiver equipped with a safety valve as a safeguard against increased pressure. Outside, it is insulated with cork to keep the temperature as low as possible. The volume of the receiver usually amounts to 20 cu. m. The liquid chlorine is pumped by means of air, compressed to 12 atm. and dried with concentrated sulphuric acid or silicagel. 

Introduction.—In industrial establishments the means of elevating and transporting hquids may be roughly classified into piston pumps and pistonless pumps, the latter including pulsometers, jet pumps, air lifts, eggs or montejus, centrifugal pumps and rotary pumps. 

Pulsometers (Fig. 13) are pistonless steam-operated displacement pumps with two chambers, AA. The steam enters these chambers alternately and is controlled by a ball or flap valve C. It enters one chamber and forces the water contained therein out through a check valve F to the discharge pipe H until... 

A number of steam-operated devices were designed, experimented, and modified since its inception. The contributions of a number of persons, viz. deUa Porta, de Cans, Boyle, Marriotte, Otto von Guericke, Dennis Papin, and Thomas Savery, toward the stody of air and steam were invaluable for the invention of the steam engine. The first steam-operated device designed professionally for practical purpose is the pulsometer pump by Thomas Savery in 1698. This was a steam-operated pump used for excavation in mines. Saveiy s steam pump had no moving parts. Steam was admitted to an empty chamber and condensed. The...
