It is noted that when oil hydraulic pump 412 is in opening state,, not only the pressure of liquid medium can be remained on prespecified range by adjusting control valve 47, and the relief valve by wherein can also the stop liquid MEDIA FLOW to steel cylinder components.Like this, just avoid frequent starting in the aerating process/stop solution press pump 412, thereby improved the working life of oil hydraulic pump 412, also reduced energy consumption simultaneously.
In the utility model, each final controlling element of each steel cylinder components is connected on the tenminal block of PLC controller by a solenoid valve respectively, thereby unifies control by 51 pairs of all steel cylinder components of PLC controller.During aerating, PLC controller 51 at first makes the fluid injection final controlling element 134 on first steel cylinder components 13 and the final controlling element 135 of giving vent to anger be in open mode, is in closed condition and return hydraulic actuator 136.At this moment, liquid medium enters in the steel cylinder 132 via filling tube and spout under the effect of oil hydraulic pump 412, and CNG is released steel cylinder 132 via air outlet and outlet pipe.The CNG that is pushed out sends into the aerating equipment for the treatment of via liquid-gas separation device 36 that comprises surge flask 35 and gas measuring apparatus 61 successively.
When level meter 72 arrived predefined minimum liquid level, PLC controller 51 was closed the fluid injection final controlling element 134 of this steel cylinder components and the final controlling element 135 of giving vent to anger, and opens back hydraulic actuator 136 simultaneously.At this moment, the exhaust process of first steel cylinder components finishes, and liquid medium wherein can return in the wet tank 411 in the supercharging storehouse 40 by liquid return pipe under the effect of residual overbottom pressure.At this moment, differential pressure switch 73 is started working, and detects the liquid status that returns of first steel cylinder components 13 at any time.
After first steel cylinder components began back liquid, through a scheduled time, PLC controller 51 began second steel cylinder components controlled, to discharge second CNG in the steel cylinder components.Similar to the controlling method of second steel cylinder components and first steel cylinder components: at first open the fluid injection final controlling element 134 of second steel cylinder components and the final controlling element 135 of giving vent to anger, and close back hydraulic actuator 136; Jia Ya liquid begins to inject second steel cylinder components then, continues the aerating process.
After the liquid medium major part in first steel cylinder components turns back to wet tank 411, there is gas pressure in the return pipeline, differential pressure switch 73 is used to detect this pressure.After PLC controller 51 received the signal that differential pressure switch 73 sends, that closes first steel cylinder components returned hydraulic actuator 136.This moment, first steel cylinder components was finished the liquid process of returning for the first time.First steel cylinder components leaves standstill the scheduled time under the situation of no any operation, afterwards, its time hydraulic actuator 136 is opened once more, makes first steel cylinder components enter the operation that secondary returns liquid.Afterwards, similarly, can return the liquid EO by the secondary that the testing result of differential pressure switch 73 is controlled first steel cylinder components.So far, the liquid process of returning of first steel cylinder components is all over.
The exhaust process of second steel cylinder components and time liquid process and first steel cylinder components are similar.1-40 group steel cylinder components can be set on the packaged type gas source unit 10.By that analogy, all steel cylinder components can be carried out exhaust in order successively and be returned the liquid operation, thereby assurance aerating process can be carried out constantly incessantly.
When last steel cylinder components on the previous packaged type gas source unit is in back liquid status, can be connected to second packaged type gas source unit by manually the pipeline of necessity being changed by ready-packaged joint, the hydraulic pneumatic final controlling element that returns that only stays liquid return pipe, last steel cylinder components is on state.Be provided with " changing trains " button in the control system, press this button, make that first steel cylinder components on second packaged type gas source unit begins bleeding, thereby realize uninterrupted aerating.
Last steel cylinder components for the treatment of previous packaged type gas source unit is returned after liquid finishes, by manually the control apparatus transposing of returning the hydraulic pneumatic final controlling element of the liquid return pipe of correspondence and this last steel cylinder components to second packaged type gas source unit.At this moment, press " changing trains " button once more, control system finishes the work control to previous packaged type gas source unit, and begins second packaged type gas source unit controlled.During equipment operation, by the manual operation, PLC controller 51 program control that the everything of complete equipment carries by equipment need not manual intervention during except that the replacing trailer.
Though should be pointed out that by above-mentioned mode of execution the utility model is described, yet the utility model also can have other numerous embodiments.Under the prerequisite that does not break away from the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
