The first step, performs 1 at electric control gear) initial parameter is set: it is usual that compressor start-up time delay is set Between the 10-30 second, preferably mode is 20 seconds, and the startup time of electromagnetic valve is set as 10-30 after start Between Miao, preferably mode is 25 seconds, and idle running restriction time K was generally between the 10-120 second, shut down Time T was generally between the 10-20 second;Wherein the electromagnetic valve startup time includes when compressor electromagnetic valve starts Between YQ and pressurizer electromagnetic valve start time ZQ and be after start between the 10-30 second;When described idle running limits Between K include that compressor idle period YK and pressurizer idle period ZK was between the 10-120 second;Institute State T downtime and include that compressor shutdown countdown YT and pressurizer are shut down countdown ZT and is in 10-120 Between Miao, the wherein said compressor shutdown time is early than described pressurizer downtime;Initial parameter is arranged After once, amendment is needed then to reset or to being currently set for amendment.
Second step, opens switch 2) starting device: started by press switchs, and pressurizer energising i.e. operates, with Time compressor start-up time delay start countdown, the compressor start time arrives, compressor start operate, with Time electromagnetic valve start the time arrive, electromagnetic valve must be electrically turn off, start gas-loaded operation;
3rd step, 3) supercharger loading and unloading: when pressurizer output pressure is more than pressurizer unloading pressure During power, for production safety, electromagnetic valve dead electricity simultaneously, pressurizer and compressor unload simultaneously, dally and limit Time processed starts inverse;During the restriction idle period opens inverse, pressurizer output pressure fills less than supercharging When putting unloading pressure value, electromagnetic valve simultaneously electric, pressurizer and compressor are with recovering load operations;Now Step 5) it is in same step, step 5) compressor loads and unloading: when Compressor Discharge Pressure is more than pressure During contracting machine unloading pressure value, for production safety, compressor electromagnetic valve dead electricity unloads, and described compressor dallies And enter idle running restriction time countdown, in countdown process, when Compressor Discharge Pressure is less than compressor During on-load pressure value, compressor electromagnetic valve obtains electric recovery and loads;Step 3) and step 5) have idle running to arrange, The two in idle running by step step 6) idle running limits: after in idle running, the restriction time terminates, final exhaust pressure When power does not drops to below supercharger on-load pressure value, pressurizer and compressor shutdown, when final pressure at expulsion Less than time below the on-load pressure value of supercharger, equipment will be by step 2) sequence starting that starts.
4th step, being in operation is by step 7) processing equipment exception: equipment state is in described temperature pre-warning In the range of value then automatic alarm but do not shut down;Equipment state be in described antioverloading numerical value, described overpressure value, Described shutdown force value and described shutdown temperature then equipment downtime;Described equipment is through step 7) recover normal after Equipment will be by step 2) sequence starting that starts.
Final step, steps performed 4 after processed safely) shut down: pressing halt switch, compressor electromagnetism Valve dead electricity unloads, and compressor shutdown countdown starts timing;Supercharger electromagnetic valve dead electricity after compressor shutdown Unloading, pressurizer simultaneously shuts down countdown and starts countdown, and pressurizer works on until pressurizer Shutdown countdown terminates, and i.e. completes to shut down.
The know-why of the present invention is described above in association with specific embodiment.These describe and are intended merely to explain this The principle of invention, and limiting the scope of the invention can not be construed to by any way.Based on herein Explaining, those skilled in the art need not pay performing creative labour can associate other tool of the present invention Body embodiment, within these modes fall within protection scope of the present invention.
