Liaocheng vehicle pressure gauge sampling failed 20

On the 25th, the reporter learned from the Liaocheng Bureau of Quality and Technical Supervision that the vehicle pressure gauge used in gas-fired vehicles had begun compulsory testing. The Liaocheng Metrology Institute had already used nearly 200 vehicles for the “oil to gas” vehicle. Table for physical examination. Twenty units of unqualified pressure gauges were identified, most of which were "out of service" and "three non-products". It is recommended to stop using and replace the new one.

“The CNG cylinder pressure gauge for vehicles is a safety instrument for measuring the pressure inside the cylinder. It can show the filling value of the pressure in the bottle. The correctness of the cylinder pressure gauge plays a crucial role in the safe use of the cylinder.” The staff of the Metrology Institute introduced a 70L cylinder as an example. The normal pressure value is 20Mpa. If the pressure indication value is less than 20Mpa within the allowable range of the specified level, it means that the error of the air volume is large; otherwise, it indicates the bottle. Internal pressure is too high, there is a certain degree of danger.

"The CNG cylinder pressure gauge for vehicles is a measuring instrument that is clearly defined by the state as a mandatory test. It must be in accordance with the periodicity prescribed by the state." The staff member said that the pressure gauge will be tested on the vehicle with professional equipment at the same time without disassembly. Not only saves time but also avoids leaks, etc. during disassembly. The staff member said that since the pressure gauge began to be inspected for one month, nearly 200 "oil-to-gas" vehicles have come to the physical examination one after another. Among them, the pressure gauges of 20 vehicles have been unqualified, and there is an overrun. Caused by the unqualified, first, the use of pressure gauges extended service; Second, the pressure gauge used is "three no product", there are indications of inaccurate quality and other hidden dangers, it is recommended to stop using. For vehicles that failed the pressure gauge verification, the city's metrological institutes would not be able to issue a certificate of conformity. It is recommended that the owner go to a regular conversion plant to replace the new one. “Taxis are the ones that come to be detected, and private cars only account for a quarter. We hope that the majority of private car owners can consciously come forward for the sake of safety for others.”
