4）、使用自主研發(fā)的、的、脈沖占空比補壓技術(shù)，將升壓環(huán)節(jié)和補壓環(huán)節(jié)合二為一，減少了一個支路及器件，也就減少了器件損壞的幾率；

5）、使用臺灣產(chǎn)柱塞泵，噪音低，補壓快，工作時間短，間接了柱塞泵的使用壽命；

c、可打印輸出報表，

d、可代替人工職守，當(dāng)無人看管時（如夜間）自動記錄壓力值；

e、計算機機可停止工作，儀表仍然繼續(xù)工作。

2、設(shè)備的組成說明：

本試驗機由壓力控制系統(tǒng)、壓力源、恒溫介質(zhì)箱、夾具和計算機五部分組成。

1）、壓力控制系統(tǒng)在控制柜中由加壓管路和電器控制兩部分組成。加壓管路由蓄能器、電磁閥、單向閥、過濾器、手動針閥、連接管路等部件組成。電器控制部分由數(shù)字控壓壓力表、溫度控制儀表、壓力傳感器、電磁閥、繼電器、過熱保護器、各種開關(guān)等組成。

2）、壓力源用來對主壓力系統(tǒng)按試驗條件提供總壓力。

3）、恒溫介質(zhì)箱主要由箱體、循環(huán)泵、加熱器、冷凝器和溫度控制系統(tǒng)組成。箱體由不銹鋼內(nèi)膽、噴塑外殼體（或不銹鋼）、保溫層、試樣支架和箱蓋組成。

4）、夾具為A型，的設(shè)計試夾具的拆裝更方便自如；楔型配合螺紋夾緊裝置使夾緊力更大。本系列夾具具有結(jié)構(gòu)合理、夾緊速度快、密封、拆卸方便的特點。

5）、計算機配備的是品牌機，通過串口與控制柜相連。品牌機是聯(lián)保，各地網(wǎng)點均可維護。

工作原理

該機的工作原理是：

1）、設(shè)定主壓力儀表的控制壓力和范圍，使壓力源提供高于支路壓力的2～3MPa的壓力儲存在蓄能器中。

2）、按照試樣的環(huán)應(yīng)力要求計算試驗壓力，并依此設(shè)定支路壓力儀表的控制壓力和范圍，運行后儀表控制電磁閥全導(dǎo)通，使試樣的壓力上升。設(shè)定壓力時進入補壓階段。

3）、補壓階段時電磁閥依據(jù)儀表數(shù)據(jù)斷續(xù)導(dǎo)通，使壓力源蓄能器中的壓力補充進試樣中。

4）、壓力源的壓力下降到設(shè)定壓力下，柱賽泵啟動工作到上停止。

5）、本機同時具有運行、停止、滲漏預(yù)警、破裂識別等功能，實現(xiàn)操作人員在試驗過程中可脫離實驗現(xiàn)場。當(dāng)試樣出現(xiàn)滲漏、破裂時自動報警并自動關(guān)閉該路，其它各路試驗繼續(xù)正常進行，直到試驗完成。在同類機型中具有優(yōu)良的性能價格比，是替代的理想產(chǎn)品。

6）、該機有串口可外配計算機，繪制壓力時間曲線，可實時查詢控壓值，可打印輸出報表，可代替人工職守，可當(dāng)計算機機停止工作時，儀表仍然可繼續(xù)工作。但計算機機不直接控制電磁閥，須經(jīng)過儀表控制，試驗時儀表不可停止工作。在做試驗過程中，還可關(guān)閉計算機機做其它商務(wù)業(yè)務(wù)，主機正常工作。當(dāng)主機與計算機連通時，主機自動將數(shù)送給計算機機，對試驗不產(chǎn)生任何影響。
