Embodiment
Two-shipper double pump two-wire hydraulic pressure air entraining substation of the present utility model, comprises booster body 6, two-wire filling machine 1 and is positioned at the fortune gas cylinder group 3 on gas transportation vehicle, fortune gas cylinder group comprises at least two fortune gas cylinders; Described fortune gas cylinder output terminal is connected with the inlet opening of described filling machine by outlet valve respectively, pressurized end is connected with the boost port of booster body by pressure charging valve respectively, booster body is parallel two groups of connecting, and two groups of booster bodies after parallel connection are connected with fortune gas cylinder group by selector valve group 2.Every group of booster body consists of an oil hydraulic pump and a motor.Selector valve group is comprised of four groups of pneumatic control valves and stop valve.During application, ebb is used one group of booster body, peak period to use two groups of booster bodies, or when one group of booster body scarce capacity, starts standby booster body enhancing boosting capability, by corresponding control system, realizes.
In order to bring into play to greatest extent the efficiency of oil hydraulic pump, and improve gas supply capacity and the air feed efficiency of air entraining substation, oil hydraulic pump preferably use the variable speed electric motors, particularly of Frequency Converter Control as power-driven mechanism, so that can according to actual needs, be exported supercharging medium with the flow of being scheduled to.
Air entraining substation pipe-line system of the present utility model, the control system providing can combine with pipe-line system, make fortune gas cylinder to low pressure port and the high-pressure mouth air feed of filling machine, when air feed ebb, when in fortune gas cylinder, CNG can meet air feed demand, control system can be controlled one group of corresponding booster body and meet air feed demand, when air feed peak, when in fortune gas cylinder, CNG can not meet air demand demand, can also automatically control another group booster body, the CNG supercharging that fortune gas cylinder is supplied with, meets peak air feed demand.。Can free adjusting add tolerance and transmission power like this, guarantee the Security of air entraining substation, improve the gas supply capacity of air entraining substation, can also improve the automation that air entraining substation is controlled, facilitate the running of air entraining substation, there is energy saving, increase the advantages such as service life of equipment.
The filling machine that two-shipper double pump two-wire hydraulic pressure air entraining substation adopts is the filling machine of two-wire, and fortune bottle group is divided into bomb group and low pressure bottle group according to process requirements.Two-wire filling machine has high pressure aerating pipeline and low pressure aerating pipeline, the front end of fortune gas cylinder all has a gas exhausting valve of controlling gas output, fortune gas cylinder is controlled and is automatically divided into bomb group and low pressure bottle group according to process, the output terminal of the gas exhausting valve of bomb group fortune gas cylinder is pooled on a high-pressure gas circuit pipeline, the output terminal of the gas exhausting valve of low pressure bottle group fortune gas cylinder is pooled on a low pressure gas circuit pipeline, the output terminal of high-pressure gas circuit pipeline and low pressure gas circuit pipeline is connected with the input end of gas circuit selector valve group respectively, the output terminal of gas circuit selector valve group is connected with low pressure aerating pipeline with the high pressure aerating pipeline of two-wire filling machine respectively.
Bomb group is on being pressurized to during limits pressure, automatic control system judges in its deposit can exceed the demand of selling gas system, do not stop pressurization system work, but open low pressure and the valve that pressure duct control valve group communicates, bomb group pressure is supplemented to low pressure bottle group.The number of times that reduces pressurization system repeatedly starting and stopping, reaches energy-saving and cost-reducing object.This process can continue to next unit energy accumulation, as has supplemented follow-up continuous second the low pressure bottle of supplementing of first low pressure bottle, by that analogy.
The oiling of a certain fortune bottle is unloaded gas process and is finished, and height pressure bottle group there will be conversion, if: headpin is high-pressure air feed bottle group after supercharging, No. 2 bottle is low pressure air feed bottle group, after headpin is unstowed, quits work, No. 3 bottle is opened low pressure air feed, and it is pressure duct air feed that No. 2 bottles transfer supercharging operation to.Subsequent control valve group is adjusted, and still guarantees that former high-pressure air feed pipeline provides high pressure air, and low pressure supply air line provides relatively low pressure.In switching the operation process of bottle group, low pressure line keeps uninterruptedly selling gas to selling the air feed of gas system, can realizing.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
