Deliver much higher flow rates than positive displacement compressors 29. discharge chamber inlet. … • These machines operate mechanically in the same way as reciprocating pumps, with the differences that leak prevention is more difficult and temperature rise is important. Centrifugal pumps • The power is applied to the fluid by the impeller and is transmitted to the impeller by the torque of the driveshaft, which usually is driven by direct-connected motor at constant speed, commonly at 1750 or 3450 r/min. Blowers • Positive-displacement blower • These machines operates as gear pumps do except that, because of the special design of the “teeth", the clearance is only a few thousandths of an inch. chamber inlet discharge gear Spur-gear pump, Positive-Displacement Pumps:Rotary Pumps • Internal-gear pump • A spur gear or pinion meshes with a ring gear with internal teeth. • Compressors deliver gas with a high pressure to volume ratio. Following are two basic types of industrial bowers and its briefing. • A single-stage blower can discharge gas at 0.4 to 1 atm gauge, a two-stage blower at 2 atm. Small-Scale LNG • Nitrogen • Compander™ • Mixed refrigeration Large-Scale LNG • Boil-off gas • Regeneration gas • Process gas • Regeneration gas • Instrument air • Boil-off gas • Vapor return blower • smaller-capacity machines discharge at pressures up to several hundred atmospheres. • interstage cooling is needed on the high-pressure units. Single-stage compressors are generally used for pressures of 70 psi (pounds per square inch) to 135 psi. • Their impeller blades may be curved forward, this would lead to instability in a pump, but not in a fan. KEY RESULT AREAS IN THERMAL POWER PLANT - . Blowers:are high-speed rotary devices (using either positive displacement or centrifugal force) that develop a max. The main difference between an air compressor and an air blower is the pressure ratio of each. High Speed Blowers. Festo Didactic KG, D73734 Esslingen.
