                                        2016-12-07 0

                                        氣密性試驗機工作原理

                                        氣密性試驗設備主要使用壓縮空氣為動力源,以氣動氣體增壓泵作為壓力源,驅動氣源壓力與輸出液壓力成正比。通過對驅動氣源壓力的調整,可以對輸出氣壓力進行無級調節。當氣壓力與增壓壓力平衡時,氣動增壓泵自動停止動作,輸出壓力也穩定在設定的壓力上。如果有泄露導致系統壓力下降,氣動氣體增壓泵自動啟動工作,進行壓力補償。通過控制氣源的進氣量,可以控制泵的動作頻率,從而控制系統的輸出流量。整套系統具有體積小、重量輕、操作簡單、安全可靠、適用范圍廣、輸出壓力可調等優點。
