Include screw compressor, air accumulator, filter, cooling driers, heater, cooling water tank, console, pipeline, valve, pressure-reducing valve,
Screw compressor, air accumulator, filter and cooling driers, are linked together by pipeline and valve, form air supply source, and compression is empty
Gas becomes that pressure-reducing valve is housed on gases at high pressure feeding supply Trunk Line, supply Trunk Line by heater heating, for controlling to send
Atmospheric pressure, flowmeter is also mounted on the supply Trunk Line after pressure-reducing valve, for measuring gas supply flow, at the same temperature thermocouple and
Pressure gauge is also installed on supply Trunk Line, is easy to observe the temperature and pressure of steam supply, from five bypass difference of supply Trunk Line point
With the five bin connections of experiment chamber, respectively with five Valve controllings, flowmeter is filled on exhaust Trunk Line, for measuring exhaust stream
Amount, while temperature thermocouple and pressure gauge are also installed on exhaust Trunk Line, the temperature and pressure for being easy to observation to be vented, from exhaust main
Pipeline divides five bypasses to be connected respectively with experiment five bins of chamber, respectively with five Valve controllings, by that will be vented after flowmeter
Supervisor's access cooling water tank, steam is cooled down, console is used for the unlatching and stopping of controlled motor, can adjust motor speed.
