                                        壓力試驗機操作注意事項

                                        2013-03-19 0
                                        壓力試驗機操作注意事項:
                                        試驗前:
                                        1、檢查油箱內的油液是否充足,可察看右側面油標,如不足,則應打開后箱板向油箱內添加至液面在油標處為宜;檢查各油灌接頭和緊固件是否松動,如有松動則擰緊之;檢查防塵罩應完整無損;檢查電氣接地、保險熔絲等安全防護措施是否有效;
                                        試驗中:
                                        2、首次使用時:將回油閥打開,關閉回油閥,接通電源,按下啟動按鈕,油泵開始工作;然后關閉回油閥,徐徐打開送不油閥活塞上升一段距離,有無卡住等現象,如有,則應卸荷、停機檢查并排除之,打開回油閥,活塞則下降到原位;
                                        4、將試件表面擦拭干凈,檢查外觀有無明顯缺陷,如有能影響試驗數值者,須更換無損試件;
                                        5、按試件下壓板定位線框放在下壓板正中,并按試件大小,轉動手輪和絲杠,調節上壓板至適當位置;
                                        6、接通測控系統電源(開關在測控箱背后),按操作步驟進行清零以及時鐘修改等各有關數據的輸入;
                                        7、按下啟動按鈕,關閉回油閥,調控送油閥,按需要速率平穩進行加荷試驗及至試件被壓碎。負荷下降,隨即打開回油閥,使油液迅速流回油箱;
                                        試驗后:
                                        8、按面板上“打印”鍵,打印機即可打印輸出該次的試驗報告;
                                        9、操作時,下壓板上升高度不得超過4cm(或立柱上標志線),以免發生意外;
                                        10、操作中禁止手等人體任何部分置于上下壓板之間,并注意試件在破碎時碎片崩出傷人;
                                        11、試后隨即清除破碎試塊,以待下次試驗。當不再做試驗時要打開回油閥,關閉送油閥,切斷電源。
