Seal Tester

Product model: MFY-2 (ordinary type)

Product purpose: MFY-2 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.

Product features

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

Test rationale

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.

Technical parameters

1.    Vacuum degree: -90kPa～0

2.    Precision: grade 1

3.    Effective size of vacuum chamber: Φ270mm×200mm (H)

4.    Air supply pressure: 0.7MPa (users prepare the air source on their own)

5.    Air supply port: Φ8 PU pipe

6.    Outline dimension: 460×360×500mm

7. Power supply: AC 220V 50Hz

8. Net weight: 12kg

Standard configuration: mainframe+seal barrel for test+air supply line

Standards followed: GB/T 15171、ASTM D3078

密封试验仪

产品型号：MFY-2（普通型）

产品用途：MFY-2密封试验仪适用于食品、制药、医疗器械、日化、汽车、电子元器件、文具等行业的包装袋、瓶、管、罐、盒等的密封试验。亦可进行经跌落、耐压试验后的试件的密封性能测试。

产品特点：

1.采用手动控制保压，操作更方便，性能更稳定。

2.所有气动原件均采用厂家产品，性能稳定可靠。杜绝了因为气动原件而产生的保压不稳现象。

3.有机玻璃（亚克力）密封桶，壁厚增15mm，有效增强密封桶的抗压强度，延长使用寿命。

4.电子保压装置，减少机械磨损，使保压时间更持久。

5.PVC操作面板，压力数字显示，分辨率0.1kPa，方便用户查看压力值。

6.内置时间显示器，保压开始计时器同步计时，方便用户记录观察保压时间，保压结束计时器自动清零。

试验原理：

通过对真空室抽真空，使浸在水中的试样产生内外压差，观测试样内气体外逸情况，以此判定试样的密封性能；通过对真空室抽真空，使试样产生内外压差，观测试样膨胀及释放真空后试样形状恢复情况，以此判定试样的密封性能。

技术参数：

1.真 空 度：-90kPa～0                    

2.精       度：1级

3.真空室有效尺寸：Φ270mm×200 mm (H)     

4.气源压力： 0.7MPa （用户自备）

5.气源接口：Φ8聚氨酯管                  

6.外形尺寸：460×360×500mm

7.电       源：AC 220V 50Hz                 

8.净       重：12kg

标准配置：主机+实验密封桶+气源线

依据标准：GB/T 15171、ASTM D3078
