Seal Tester密封試驗儀

Product model產品型號: MFY-1 (economic type) （經濟型）

Product purpose: MFY-1 seal tester is applicable to the seal test for the packing bag, bottle, pipe, jar and box in the field of the food, pharmacy, medical apparatus and instruments, daily chemical, auto, electronic components, and stationery. In addition, it could test the seal performance of the test piece after the fall and pressure test.

產品用途：MFY-1密封試驗儀適用于食品、制藥、醫療器械、日化、汽車、電子元器件、文具等行業的包裝袋、瓶、管、罐、盒等的密封試驗。亦可進行經跌落、耐壓試驗后的試件的密封性能測試。

Product features產品特點                                 

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，性能更穩定。

2.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品，性能穩定可靠。杜絕了因為氣動原件而產生的保壓不穩現象。

3.The wall thickness of the seal barrel made of the high-quality organic glass (acrylic)increases to 15mm, which could effectively reinforce the compressive strength of the seal barrel, and prolong its service life.

3.有機玻璃（亞克力）密封桶，壁厚增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 pressure pointer display is real-time and accurate, which is easier for user to check the pressure value.

Test rationale

5.PVC操作面板，壓力指針顯示，即時，方便用戶快捷查看壓力值。

Test rationale試驗原理：

Vacuumize the vacuum chambersuch 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生內外壓差，觀測試樣內氣體外逸情況，以此判定試樣的密封性能；通過對真空室抽真空，使試樣產生內外壓差，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。
