一、产品简介：

该仪器主要用于检测雷式夹质量是否符合要求，也用于测量按标准稠度的水泥净浆填满雷式环模中，经养护及沸煮一定时间后水泥试件在雷式夹两指针间距离的增值来判定水泥的安定性。主要用于检测雷式夹质量是否符合要求，也用于测量沸煮前后水泥试件在雷式夹两指针间距离的增值来判定水泥的安定性。产品符合GB/T1346、ISO9597标准要求。该仪器由支架、标尺、底座等零件组成。

Product introduction:

The instrument is mainly used to test whether the quality of the lightning clamp meets the requirements, and also to measure the cement paste filled with the standard consistency in the lightning ring mold. After curing and boiling for a certain period of time, the cement test piece is in the two pointers of the lightning clamp The increase of the distance between the two to determine the stability of the cement. It is mainly used to check whether the quality of the lightning clamp meets the requirements. It is also used to measure the increase in the distance between the two pointers of the cement clamp before and after boiling to determine the stability of the cement. The products meet the requirements of GB / T1346 and ISO9597 standards. The instrument consists of parts such as a stand, a ruler and a base.

二、技术参数：

★专用砝码重量 300g 

★A值刻度板A小刻距 0.5㎜ 

★净重 ≈1.65㎏

Second, the technical parameters of the cement lightning clamp tester:

★ Special weight 300g

A small scale of A value scale A 0.5㎜

★ Net weight ≈1.65㎏

三、操作规程：

★雷式夹试件的沸煮

先测量带有试件并经养护的雷式夹两指针好的的间距**到0.5mm，并用编号做记录，按着将雷式夹连同试件放入沸煮箱重蓖板上，指针朝上试件之间互补交叉，然后在30±5min内加热至沸腾，并恒温3h±5min

后按测得沸煮后两指针好的间距与沸煮前的差值多少来判断试件的合格与否。

★雷式夹用后去掉式样及污物后放妥，严禁堆放或其它物体相互挤压。

★雷式夹每次使用前对雷式夹进行弹性要去检验，具体做法如下：将雷式夹一指针根部挂在测定仪昡线上，另一指针根部挂300g砝码，两指针间距离加2X=17.5±2.5mm,去掉砝码后指针恢复原尺寸。检验合格后方可使用。

★雷式夹试件的制备方法：

将预先准备好的雷式夹放在已稍擦油的玻璃板上，并一只手用宽10mm小刀插到15次左右然后抹平，盖上稍涂油的玻璃板，压上配重块，立即将雷式夹连同试件和玻璃板移至湿气养护箱（控制温度20±3度温度大于90%）内养护24±2h

Third, the operating procedures of the cement lightning clamp tester:

★ Boiling of Lightning Clip Test Pieces

First measure the good distance between the two pointers of the cured clip with the test piece ** to 0.5mm, and use the number to make a record. Then place the clip with the test piece on the heavy caster plate in the boiling box. Complementary cross between the test pieces facing upward, then heat to boiling within 30 ± 5min, and keep constant temperature for 3h ± 5min

Then, measure the difference between the good distance between the two pointers after boiling and before boiling to determine whether the test piece is qualified.

★ After using the thunder clip, remove the style and dirt and put it away. It is strictly prohibited to stack or squeeze other objects.

★ Be sure to check the elasticity of the lightning clamp before using the lightning clamp each time. The specific method is as follows: one of the pointer of the lightning clamp is hung on the line of the tester, and the other is 300g weight, the distance between the two pointers Add 2X = 17.5 ± 2.5mm. After removing the weight, the pointer returns to its original size. Can be used only after passing inspection.

★ Preparation method of lightning clamp test piece:

Place the prepared thunder clip on the glass that has been slightly oiled, and insert it with a 10mm wide knife about 15 times with one hand and then smooth it. Cover the glass plate with oil and press the weight , Immediately move the lightning clamp together with the test piece and the glass plate to the moisture conservation box (control temperature 20 ± 3 degrees, temperature greater than 90%) and maintain it for 24 ± 2h

四、使用与维护：

★雷式夹每次使用前对雷式夹进行弹性要去检验，具体做法如下：将雷式夹一指针根部挂在测定仪昡线上，另一指针根部挂300g砝码，两指针间距离加2X=17.5±2.5mm,去掉砝码后指针恢复原尺寸。检验合格后方可使用。
