FUNDAMENTAL PRINCIPLES OF DIAPHRAGM METERS

mounted on each side of a casting partition form the four chambers of the meter. As the chamber fills, it moves the diaphragm and the gas in the filled chamber on the other side of the diaphragm is forced out. The filling and emptying of the compartments are controlled or timed by a D-slide rectilinear valve reciprocating over a multi-port

Influence of Air Temperature and Velocity for

01-01-2017  Contrarily, the gradient is increased by velocity from 5 gram/(m/s) to 9 gram/(m/s). Based on this fact, it can be concluded that the effect of temperature is less significant at high air velocity. The basic principle of drying process is to transport water vapor from wet object to the air. Velocity of air is proportional to the mass flow rate of air.

Diaphragm pump - Wikipedia

Diaphragm Pumps deliver a hermetic seal between the drive mechanism and the compression chamber, allowing the pump to transfer, compress, and evacuate the medium without a lubricant. An elastomeric diaphragm can be used as a versatile dynamic seal that removes many of the limitations found with other sealing methods.
