Pressurised air supply, storage, drying and monitoring
6
Shut-off valve
8
Compressor [2.1]
condenses the air drawn in at approx. 6,0 bar.
22 Compressor air intake filter [1.1]
23 Safety valve compressor
24 Safety valve "cable pressure" [10.5]
protects the pressurised air consumer load against excessive pressure.
25 Compressor temperature sensor
for ACS
27 Fan [E1]
vents the compressor area.
28 Air storage tank [9.1],
stores the dried pressurised air..
29 Safety valve "high pressure" [10.4]
protects the air storage tank (
28
) [9.1] against excessive pressure.
32 Pressure reducer [12.1]
reduces the high-pressure to the designated output pressure. Preset.
33 Non-return valve [4.1]
prevents a reversed flow of pressurised air from the distribution device.
35 Air dryer [5.1]
dries the pressurised air alternatively in one of the two containers, while the drying agent is regenerated in
the other container.
36 Solenoid valves for air dryer [left:Y1, right: Y2]
control the air flow alternatively by one of the two drying agent containers and lead the regeneration air
flow from the passive drying agent container outside (to condensate surge tank).
37 Micro filter [1.5]
protects the control and measurement devices from contaminations.
38 Pressure limiting valve [8.1]
opens when the air flow has reached a pressure of 5.5 bar after leaving the air dryer (
35
) [5.1].
39 Double non-return valve [6.1]
routes the dried pressurised air in the active drying agent container to the air storage tank (
28
) [9.1] and
returns a part of the air flow for regeneration of the drying agent into the passive drying agent container..
40 Pressure monitor [F6]
monitors the pressure in the air storage tank (
28
) [9.1] and switches the compres-
sors on and off once the upper and lower pressure value is reached.
41 Humidity sensor for MFR
monitors the relative humidity of the output air. When reaching the upper limit,
the MFR activates fault „F“ and shuts the system down.
42 Pressure sensor „compressor pressure” [10.1]
for ACS.
Measures the common output pressure of both compressors.
The code designations specified in squared brackets [ ] correspond to the pneumatic and electrical plans in the annex.
