摘　　要：试车台贮箱增压时,为了确保减压器的稳定性和可靠性,根据减压器工作原理和特性采取了减压器大、小流量试验、低入口压力稳定性试验、并联试验以及并联使用动态试验,减压器关键元件之一的膜片工作时间确定试验等,有效避免增压系统单点失效模式发生,提高增压系统增压能力。通过试验及采取适当措施,更好的保证了减压器工作的稳定性和可靠性。Several measures were introduced in this paper for reliability improvement of test stand gas supplying system, focusing on the stable and reliable operation of pressure reducer. These measures includes maximum and minimum flow tests, low inlet pressure stability test, parallel connection test, parallel connection dynamic test and diaphragm life test. All the measures effectively improved the reliability and stability of the pressure reducer.
