Automobile fuel tank blasting pressure withstanding testing system

Abstract

The invention discloses an automobile fuel tank blasting pressure withstanding testing system. The automobile fuel tank blasting pressure withstanding testing system comprises an auxiliary fuel tank, a motor, a pressure control variable pump, a proportional pressure valve, a one-way valve, an overflow valve, an unloading overflow valve, a safety and stop valve bank, an energy accumulator, a high-pressure filter, a high-pressure ball valve, a low-pressure ball valve, a pressure measuring joint, a pressure gauge, a pressure sensor, a fuel tank to be tested, a stress sensor and a return fuel filter. By the automobile fuel tank blasting pressure withstanding testing system, complicated alternating dynamic adjustment of testing pressure is implemented in an automobile fuel tank blasting pressure withstanding testing process, and a comprehensive and perfect automobile fuel tank safety and reliability evaluating system can be obtained. In addition, by the variable pump, the pressure is remotely and dynamically controlled, working pressure and stress states of an automobile fuel tank are acquired, and the blasting pressure withstanding performance of the automobile fuel tank is reflected. The overall automobile fuel tank blasting pressure withstanding testing system is simple and reliable and high in practicality, and has high engineering promotion value.

Description

technical field [0001] The invention relates to the field of automobile fuel tank testing, in particular to an automobile fuel tank burst pressure test system. Background technique [0002] The fuel tank, as a container for storing fuel in the car, is a key safety component that cannot be ignored in the car fuel system. With the development and progress of automobile technology, fuel tanks are usually designed into various shapes according to needs, so as to maximize the use of the space under the body and meet the design requirements of lightweight automobiles. [0003] The number of automobiles and the speed of automobiles in our country are gradually increasing, and the research on fuel tank performance testing equipment has become an urgent task. With the gradual improvement of the safety and reliability of the automotive fuel supply system, it is required that the fuel tank detection system can evaluate its performance accurately and effectively. Among them, the burst...
