壓力試驗機(ji)上下限介紹：
1.安裝壓(ya)(ya)(ya)力試(shi)驗(yan)機時(shi)，應注意排(pai)凈壓(ya)(ya)(ya)力測量(liang)(liang)儀器及其(qi)接管內的(de)空(kong)氣.在升(sheng)壓(ya)(ya)(ya)過(guo)程(cheng)中若發現升(sheng)壓(ya)(ya)(ya)速(su)度明(ming)顯增(zeng)快或(huo)減慢(man)的(de)現象時(shi)，應立(li)即停止水壓(ya)(ya)(ya)泵，尋求升(sheng)壓(ya)(ya)(ya)速(su)度異(yi)常的(de)原(yuan)因并予以處置。壓(ya)(ya)(ya)力測量(liang)(liang)儀器的(de)示值不為(wei)“零”時(shi)，嚴禁拆卸承壓(ya)(ya)(ya)管道(dao)上的(de)一切承壓(ya)(ya)(ya)件和拆裝受試(shi)工件，嚴禁旋轉(zhuan)承壓(ya)(ya)(ya)管道(dao)的(de)街頭。泄壓(ya)(ya)(ya)時(shi)必須使壓(ya)(ya)(ya)力緩慢(man)下降。若發現試(shi)前準備或(huo)試(shi)驗(yan)過(guo)程(cheng)中某一環節(jie)有失(shi)誤，而可能影響試(shi)驗(yan)結果的(de)正確性時(shi)，則該次(ci)試(shi)驗(yan)無效。
2.壓(ya)(ya)(ya)(ya)(ya)力(li)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)機(ji)(ji)的(de)(de)主要技(ji)術參(can)數是最(zui)大(da)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)力(li)，即測(ce)(ce)(ce)試(shi)(shi)(shi)物(wu)體能承受多大(da)的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)才會變(bian)形或者(zhe)碎裂，通常用(yong)(yong)(yong)公斤力(li)來表示(shi)壓(ya)(ya)(ya)(ya)(ya)力(li)，單位牛(niu)頓N、千牛(niu)KN。測(ce)(ce)(ce)試(shi)(shi)(shi)范(fan)圍(wei)一般是以(yi)最(zui)大(da)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)力(li)為(wei)上限(xian)向(xiang)下(xia)兼容。加(jia)壓(ya)(ya)(ya)(ya)(ya)裝(zhuang)置一般采用(yong)(yong)(yong)液壓(ya)(ya)(ya)(ya)(ya)或氣壓(ya)(ya)(ya)(ya)(ya)加(jia)壓(ya)(ya)(ya)(ya)(ya)。不同(tong)行業的(de)(de)材質(zhi)抗(kang)壓(ya)(ya)(ya)(ya)(ya)強度(du)不同(tong)，因此(ci)壓(ya)(ya)(ya)(ya)(ya)力(li)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)機(ji)(ji)的(de)(de)測(ce)(ce)(ce)量(liang)(liang)范(fan)圍(wei)也(ye)有(you)所不同(tong)，雖(sui)然測(ce)(ce)(ce)試(shi)(shi)(shi)范(fan)圍(wei)是以(yi)最(zui)大(da)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)力(li)為(wei)上限(xian)向(xiang)下(xia)兼容，但是用(yong)(yong)(yong)大(da)量(liang)(liang)程的(de)(de)設備去(qu)測(ce)(ce)(ce)試(shi)(shi)(shi)抗(kang)壓(ya)(ya)(ya)(ya)(ya)要求很低的(de)(de)物(wu)體，試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)結(jie)(jie)果(guo)的(de)(de)精確度(du)就(jiu)難(nan)保證，就(jiu)如同(tong)用(yong)(yong)(yong)磅(bang)秤去(qu)稱1根大(da)頭針的(de)(de)重(zhong)量(liang)(liang)，是無法讀(du)出(chu)讀(du)數的(de)(de)。因此(ci)在選(xuan)購壓(ya)(ya)(ya)(ya)(ya)力(li)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)機(ji)(ji)時(shi)應該(gai)先了解該(gai)儀器的(de)(de)適用(yong)(yong)(yong)范(fan)圍(wei)。 加(jia)載部分采用(yong)(yong)(yong)矩形框架(jia)結(jie)(jie)構(gou)，液壓(ya)(ya)(ya)(ya)(ya)系(xi)統安裝(zhuang)在主機(ji)(ji)的(de)(de)右(you)側(ce)，結(jie)(jie)構(gou)簡捷明快、造型(xing)美觀.設有(you)獨立的(de)(de)液晶式(shi)控制(zhi)器，控制(zhi)高(gao)精度(du)電液伺服(fu)閥，驅(qu)動液壓(ya)(ya)(ya)(ya)(ya)缸，可(ke)實(shi)現整(zheng)個試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)過(guo)程中試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)參(can)數的(de)(de)設定、工(gong)作狀態的(de)(de)自動控制(zhi)、數據(ju)自動采集、處理(li)分析(xi)、顯示(shi)，快捷方便、智能、美觀.可(ke)外接品牌微機(ji)(ji)，配有(you)混(hun)(hun)凝土壓(ya)(ya)(ya)(ya)(ya)力(li)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)機(ji)(ji)專用(yong)(yong)(yong)Windows中文軟(ruan)件，根據(ju)國家標準進行測(ce)(ce)(ce)量(liang)(liang)和輸(shu)出(chu)混(hun)(hun)凝土的(de)(de)性能參(can)數，顯示(shi)試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)數據(ju)及結(jie)(jie)果(guo).試(shi)(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)結(jie)(jie)束后下(xia)壓(ya)(ya)(ya)(ya)(ya)盤下(xia)降迅速.采用(yong)(yong)(yong)液壓(ya)(ya)(ya)(ya)(ya)泵機(ji)(ji)組及電液伺服(fu)閥,大(da)大(da)提高(gao)品質(zhi)設備品質(zhi)。
