LABORATORY SYSTEM FOR RESEARCH WORK general ventilation

摘要

The invention relates to a laboratory apparatus for the study of the work of general ventilation and can be used in the laboratory.; The utility model provides a technical effect is to reduce the complexity of the measurement.; The laboratory facility for investigation operation comprises general ventilation hood, provided with a movable wall and connected to a suction pipe of the fan on the pressure pipe is installed with the tube located therein receivers total and static pressure, connected to the device for measuring differential pressure. Tube disposed therein receivers total and static pressure has a cylindrical shape with two coaxial openings at its front and rear sides, separated by an inclined plate overlapping the cross section of the latter. 1 SP f ly-2 Fig.
