Product features產(chǎn)品特點:

1. It is in use of the manual control to maintain the pressure, such that it is more convenient in operation with more steady performance.

1.采用手動控制保壓，操作更方便，性能更穩(wěn)定

1. All the pneumatic components come from the famous vendors with steady and reliable performance, such that the unsteady pressure arising from the pneumatic components is absoluy impossible.

2.所有氣動原件均采用廠家產(chǎn)品，性能穩(wěn)定可靠。杜絕了因為氣動原件而產(chǎn)生的保壓不穩(wěn)現(xiàn)象。

3.The seal barrel is made of thickened organic glass (acrylic), whose wall thickness reaches 15mm, effectively reinforcing the compressive strength of the seal barrel, and prolonging its service life.

 3.有機玻璃（亞克力）密封桶，壁厚增至15mm，有效增強密封桶的抗壓強度，延長使用壽命。

 4.The electronic pressurizer could minimize the mechanical wear, and maintain the pressure for longer.

 4.電子保壓裝置，減少機械磨損，使保壓時間更持久

5.The PVC operation panel with the resolution ratio of pressure digital display standing at 0.1kPa makes it easier for user to check the pressure value.

 5.PVC操作面板，壓力數(shù)字顯示，分辨率至0.1kPa，方便用戶查看壓力值。

6.It is in-built with time display, when starting the pressure maintenance, the timer keeps the time at the same time, which makes it easier for user to record and observe the pressure maintenance time. When the pressure maintenance comes to an end, the timer will automatically reset.

6.內(nèi)置時間顯示器，保壓開始計時器同步計時，方便用戶記錄觀察保壓時間，保壓結束計時器自動清零。

Test rationale試驗原理：

Vacuumize the vacuum chamber, such that the test piece dipped in the water could generate differential pressure inside and outside, observe the escape of the air within the test piece, so as to determine the seal performance of the test piece. Vacuumize the vacuum chamber, such that the test piece could generate differential pressure inside and outside, observe the swell of the test piece and the shape recovery of the test piece after releasing the vacuum, so as to determine the seal performance of the test piece.

通過對真空室抽真空，使浸在水中的試樣產(chǎn)生內(nèi)外壓差，觀測試樣內(nèi)氣體外逸情況，以此判定試樣的密封性能；通過對真空室抽真空，使試樣產(chǎn)生內(nèi)外壓差，觀測試樣膨脹及釋放真空后試樣形狀恢復情況，以此判定試樣的密封性能。
