As shown in Fig. 1～2, the operation principle of the present invention is:
First, require PLC program according to actual functional capability, PLC program is imported PLC 3；Preparation is finished
After, the PLC that switches on power 3 realizes carrying out ECM communication with electromotor 2；Pressing start button, PLC 3 provides startup
Instruction, electromotor 2 starts to start；When the rotating speed of electromotor 2 arrives 800rpm/min, PLC 3 is given opens bypass electricity
Magnet valve instructs, and bypass opens, and that sets up rapidly needed for machine is intrinsic pressure, when system detect intrinsic pressure reach setting value time, can stand
Horse makes bypass close, and makes air compressor machine 1 maintain with the pressure state of balance, and now, electromotor 2 is in idling mode.Air compressor machine 1
Pressing start button, PLC 3 provides enabled instruction, and electromotor 2 starts to start, if now not pressing load button, PLC
Controller 3 can provide rotating speed and maintain the instruction of 1350rpm/min；Now, air compressor machine 1 is in off-load state；When pressing loading
After button, PLC 3 can provide rotating speed to electromotor 2 and rise to the instruction of maximum speed, and now, first loads electromagnetic valve 51
Obtaining electric-opening, (loading electromagnetic valve with off-load electromagnetic valve is mutual lock control, and one obtains electric in the first off-load electromagnetic valve 52 dead electricity closedown
So another one dead electricity simultaneously.) compressed gas loads electromagnetic valve 51 from first and enter the valve opening chamber of intake valve 4, intake valve 16
Valve block is opened, and now, compressor head can pull at into one big strand of gas, allows the initial fuel injection pressure of gs-oil separator 4 in 30 seconds
Setting up the pressure of about 10bar, when in system detects oil tank, injection pressure reaches setting value, resolute meeting loads first
Electromagnetic valve 51 dead electricity, the first off-load electromagnetic valve 52 obtains electric, and one compressed gas enters the pass valve pocket of intake valve 16, by intake valve 16
Valve block close, now air compressor machine 1 enters the state of off-load.Compressor is by above action, it is achieved that air compressor machine 1 is energy-conservation fuel-efficient
Purpose.
When client's stopping gas, when the air pressure in gs-oil separator 4 is close to when setting pressure, and unloader 14 is slowly beaten
Opening, the gas in gs-oil separator 4 is gradually discharged by intake valve 5, the curved decline of pressure in gs-oil separator 4, air inlet
Piston stop motion in valve 16, emits the residual gas in gs-oil separator 4.
When client is temporarily without gas, the pressure of gs-oil separator 4 rises sharply, now, and the off-loading in described first group of gas circuit
Pressure-regulating valve on branch road is opened, and gas is quickly discharged in the air filter on intake valve 16 row from gs-oil separator 4
Run out, make the gas pressure in gs-oil separator 4 stable within the scope of setting, it is to avoid because instantaneous pressure changes gas
The impact that pressure element causes.As the preferred structure of the present embodiment, described off-loading branch road is provided with two gears, one grade and two
Gear (i.e. one grade is the branch road of the first pressure-regulating valve 12, and two grades is the branch road of the second pressure-regulating valve 13), due to the present embodiment
In full-automatic unmanned supervision air compressor machine be mainly used in down-the-hole water drilling rig, one grade is mainly applicable to 200m depth below,
When being less than 500m more than 200m, then using two gears, if use two gears always, fuel economy does not has the former good.One
Shelves pressure at expulsion is 24bar (the unlatching pressure of the i.e. first pressure-regulating valve), and two gears use 35bar, and (the i.e. first pressure is adjusted
The unlatching pressure of joint valve), when client is without gas, the second electromagnetic valve 11 on a grade obtains electric, and the first pressure-regulating valve 12 is opened,
Compressed gas enters closes valve pocket, is closed by valve block, and air compressor machine enters off-loading state.Two gear operation principles are identical with one grade.
PLC 3 of the present invention can detect any fault of equipment, the most faulty appearance, can serious according to fault
Grade, (fault is relatively light, does not interferes with normal use, such as excessive discharge temperature but still in peace to send fault pre-alarming warning to client
In gamut, the early warning of fuel oil position reminds client to supplement fuel oil etc. timely) and protect stopping alarm (as pressure superelevation, temperature surpass
Height, the engine water tank too low warning of water level etc.).
Present configuration is reasonable, designs ingenious, is monitored whole air compressor system by PLC, by temperature
Degree the sensor 17 and cooperation of pressure transducer 18, obtain in real time air compressor system temperature and pressure (i.e. air compressor machine 3 uses gas
The size of amount) situation of change, thus be automatically adjusted the work efficiency of air compressor machine by PLC 3, control mode is accurate,
Energy-saving effect is notable, its power saving rate up to
40%～50%.Meanwhile, present invention, avoiding the rush of current situation that air compressor machine is subject to when frequently opening, extend
The service life of system, it is ensured that the use quality of system.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
