本发明的工作原理：Working principle of the present invention:
该液压式天然气汽车加气站是利用液压装置将抗磨性液压油直接注入液压式高压气瓶中，往复压缩天然气到20Mpa，然后送至高压储气瓶组中，再通过加气机把高压天然气注入汽车的储气瓶内达到给汽车加气的目的。随着汽车加气的进行，储气瓶里的压缩天然气压力下降，液压装置继续压缩天然气往高压储气瓶里补充压缩天然气，不需要采用其他的增压设备，即用液压装置对天然气加压来替代压缩机压缩天然气，这样既减少设备投资又能降低能耗。The hydraulic natural gas vehicle refueling station uses a hydraulic device to directly inject anti-wear hydraulic oil into a hydraulic high-pressure cylinder, reciprocately compresses the natural gas to 20Mpa, and then sends it to the high-pressure gas storage cylinder group, and then passes the gas dispenser to release the high-pressure Natural gas is injected into the gas storage cylinder of the car to achieve the purpose of refueling the car. As the car is refueled, the pressure of the compressed natural gas in the gas storage bottle drops, and the hydraulic device continues to compress natural gas to replenish the compressed natural gas in the high-pressure gas storage bottle. No other booster equipment is needed, that is, the hydraulic device is used to pressurize the natural gas To replace the compressor to compress natural gas, which not only reduces equipment investment but also reduces energy consumption.
本发明的工作程序：Working procedure of the present invention:
本加气装置可先将高压储气瓶组里充满20Mpa的压缩天然气，高压储气瓶组分成两组。当打开气枪给汽车加气时，一组气瓶开始供气，同时开启液压泵压缩天然气给气瓶补充压缩天然气。当液压式高压气瓶里天然气的压力与工作压力接近平衡时切换到另一组备用高压气瓶里继续加气直至到达客户要求。The gas filling device can first fill the high-pressure gas storage cylinder group with 20Mpa compressed natural gas, and the high-pressure gas storage cylinder group is divided into two groups. When the air gun is turned on to refill the car, a group of gas cylinders starts to supply gas, and at the same time, the hydraulic pump is turned on to compress the natural gas to replenish the compressed natural gas to the gas cylinders. When the pressure of the natural gas in the hydraulic high-pressure gas cylinder is close to the balance with the working pressure, switch to another set of spare high-pressure gas cylinders and continue filling until the customer's requirements are met.
