Shelves pressure at expulsion is 24bar (i.e. the Opening pressure of first pressure regulating valve), and two gears use 35bar, and (i.e. first pressure is adjusted
Save the Opening pressure of valve), when client is without gas, the second magnetic valve 11 on a grade obtains electric, and first pressure regulating valve 12 is opened,
Compressed gas enter valve pocket of entering the GATT, and valve block is closed, and air compressor machine enters off-loading state.Two gear operation principles are identical with one grade.
Any failure of the energy testing equipment of the utility model PLC 3, once faulty appearance, can be according to failure
Menace level, to client send fault pre-alarming alarm (failure is lighter, does not interfere with and normally uses, such as excessive discharge temperature but still
In safe range, fuel oil position early warning reminds client timely to supplement fuel oil etc.) and protect stopping alarm (such as pressure superelevation, temperature
Too low alarm of degree superelevation, engine water tank water level etc.).
The utility model is rational in infrastructure, designs ingenious, and whole air compressor system is monitored by PLC, borrows
The cooperation of temperature sensor 17 and pressure sensor 18 is helped, temperature and pressure (the i.e. air compressor machine 3 of air compressor system is obtained in real time
The size of gas consumption) situation of change, so as to automatically adjust the operating efficiency of air compressor machine by PLC 3, control mode essence
Really, significantly, its power saving rate is up to 40%~50% for energy-saving effect.Meanwhile, the utility model avoids air compressor machine and is frequently opening
When the rush of current situation that is subject to, extend the service life of system, it is ensured that the use quality of system.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
