                                        循環疲勞試驗機工作原理

                                        2016-08-02 0
                                        循環疲勞試驗機工作原理:
                                        1)循環壓力的產生
                                        壓力源源于高壓空壓機,經過調壓閥調節壓力,使之穩定在一個恒定的壓力值,通過被測試閥門和排氣閥的打開、關閉,產生一個按一定規律變化的交變壓力。該交變壓力與循環系統的基礎壓力相同。循環壓力的動力源由恒定壓力的氣壓站提供的。
                                        2)被測試閥門的開關
                                        在試驗過程中,被測試閥門要不斷的打開、關閉,主要是通過電動機往復的旋轉來實現的。開關的速度可調節電動機的轉速來實現。
