Automotive oil to gas: safety issues can not be ignored

Looking around in recent years the gas instead of oil, natural gas compared with gasoline, but also safety and environmental protection, and the considerable economic, by taxi, private car drivers of all ages, but security incidents have occurred. In recent years, the various parts of the natural gas vehicle filling explosion, gas cylinder leak caused by fires and other accidents. In addition, the unauthorized modification of the security stability suffering from gas cylinders, gas cylinders extended service has been very conspicuous. The gas cylinders are pressure vessels, the maximum bearing pressure of 20MPa, the explosive power as much as a bomb. It is understood that occurred in the the Dongying accident will be converted into a pressure 4MPa pressure container.
To protect natural gas Car Security, and should strictly adhere to safety rules in the filling gas, driving and handling incidents.
Filling gas. Filling gas, the passengers on board should be allowed to get off plus gas; To turn off the ignition switch, fuel change-over switch placed in the middle or petrol position; inflated by the professionals of the filling stations, the filling pressure shall not exceed the national standard 20MPa; filling is completed, you should check the gas supply system if there are leaks.
Disassembly related to high voltage components, to avoid unsafe operation; open the valve, the person shall stand to the front of the cylinder valve port, the valve should be opened slowly, gradually open after ventilation; while driving to avoid the cylinders and pipelines and obstacle collision, the gas supply system has air leaks should be immediately removed, and switching to gasoline fuel.
To properly handle the driving accident. Moving the event of gas leaks, fires, crashes and other accidents, emergency lights, emergency stop should be opened immediately according to the actual situation; turn off the power; cut off the oil, gas; evacuation of passengers; close the cylinder cut-off valve; contact qualified fixed-point tuning and the relevant departments of natural gas vehicles to the scene.
To protect the security, maintenance of gas installations should be combined with the car at all levels of maintenance at the same time. Before each trip, you should check the fastening of the parts. Check pipeline and junction leakage; monthly check for a high-pressure pipeline filters, solenoid spool; adjust the pressure relief valve pressure at all levels; six months to the overhaul of a pressure reducing valve and the gas supply system; "cylinders Safety Supervision provides, gas cylinders, two years a test failure should be promptly replaced. Sludge to remove the cylinder surface at any time, so as not to affect the gas cylinder valve, safety explosion-proof valve technology performance; high pressure system failure, the driver shall not disassemble, alteration, repair, adjust the reducer.
Throughout the process of the implementation of the gas instead of oil, due to the gas instead of oil "problem involving hundreds of thousands of rental vehicles, lack of supervision is likely to allow some of the qualifications, skills garage illicit intervention modified the transformation of the market. It is also a huge security risk, it will also restrict the social effects of this excellent initiative. Security concerns is an objective reality, the long term implementation of the gas instead of oil to comply with the law of development, but if you want to really ensure the effective implementation of this initiative, we must seriously face and positive solution to many security risks.
