砂浆含气量测定仪 LS-546

砂浆含气量测定仪是我公司依据JGJ/T70-2009(建筑砂浆基本性能试验方法标准)和JISA1228规范,用于测量砂浆中的空气含量。测定原理是根据气态方程,保持一定压力的气室和装满试料的容器之间,开闭压力平衡,两个容器内的压力达到平衡时,气室里压力减少的量即是砂浆中空气所占的百分比,在压力表上显示出的即是试料中的空气含量。

一、产品简介:

砂浆含气量测定仪是我公司依据JGJ/T70-2009(建筑砂浆基本性能试验方法标准)和JISA1228规范,用于测量砂浆中的空气含量。测定原理是根据气态方程,保持一定压力的气室和装满试料的容器之间,开闭压力平衡,两个容器内的压力达到平衡时,气室里压力减少的量即是砂浆中空气所占的百分比,在压力表上显示出的即是试料中的空气含量。

Product introduction:

The mortar gas content measuring instrument is used by our company to measure the air content in mortar according to JGJ / T70-2009 (standard for basic performance test methods of building mortar) and JISA1228. The measurement principle is based on the gaseous equation. The pressure between the gas chamber that maintains a certain pressure and the container filled with the sample is balanced. When the pressure in the two containers reaches equilibrium, the pressure in the gas chamber is the air in the mortar. The percentage that is shown on the pressure gauge is the air content in the sample.


二、工作原理:

根据气态方程,保持一定压力的气室和装满试料的容器之间,开闭压力平衡时,两个容器的压力达到平衡时,气室压力减少的量即是砂浆中的空气含量所占的百分比,在压力表上表示出的即是试料中的空气含量。

Second, the working principle:

According to the gas state equation, between the gas chamber that maintains a certain pressure and the container filled with the sample, when the opening and closing pressure is balanced, when the pressure of the two containers reaches equilibrium, the amount of pressure reduction in the gas chamber is the air content in the mortar. The percentage is shown on the pressure gauge as the air content in the sample.

五、使用方法:

★将拌好的混凝土分二次装入钵体,

★分别振实,排除气泡,刮去表面多余部分,

★盖上盖子,将压紧阀对衬均匀拧紧,关闭所有阀门。

★用充气阀充气至――。点的位置,停3-5秒,

★按动进气阀,表针所指的位置**是混凝土含气量的实测数值(红色)

★测定完毕,缓慢的松动调压阀,

★使表针慢慢的回到零点,A猛松,防止指针撞击零点定位柱,影响精度。

Five, use method:

★ Put the mixed concrete into the bowl twice,

★ Simulate separately, eliminate air bubbles, scrape off excess surface,

★ Close the lid, tighten the compression valve evenly and close all valves.

★ Inflate with inflation valve to ——. Point position, stop for 3-5 seconds,

★ Press the air inlet valve, the position indicated by the hand ** is the actual measured value of the concrete air content (red)

★ After the measurement is completed, slowly loosen the pressure regulating valve,

★ Make the hand slowly return to zero, and A will loosen, preventing the pointer from hitting the zero positioning column, affecting the accuracy.


六、操作规程:

1)称重空钵的重量,并记录。

2)把密封环放到钵上,然后把夹紧环挂到钵的边框上。

3)往钵内填满砂浆,然后晃动/压实它。

4)揭开密封环,用大铁锤使砂浆超过钵的边缘。

5)称重满钵时的重量,然后减去记录的空钵的重量,计算出散货的密度。

6)现在用一块干净的布清理钵的边缘。

7)把上部分放到擦干净的钵上,然后扣紧四周的夹紧器。

8)打开停止阀,控制杆向上。然后用洗瓶往停止阀里注入水,直到水从停止阀中溢出来,没有气泡。

9)拧动左边半圆形的手柄打开气泵,直到压力计的指针指向距离“%AIR下方3的位置”。现在慢慢向左拧排气阀的螺丝,直到压力计的指针准确的指到“%AIR下方3的位置”。如果指到这个位置的话,请顺时针方向拧动螺丝关闭排气阀。(“%AIR下方3的位置”,也**是初压点,和混凝土含气量作用相同。)

10)关闭停止阀。

11)当指针归零后开始检测。按摇杆大约20秒,直到压力计的指针不再动。

12)在压力计上直接读出含气量百分比。

13)慢慢打开停止阀。然后向左转螺丝,把多余的压力放掉。

14)打开上部分,把钵腾空,然后清理干净,把所有的零部件擦干[1]

Six, operating procedures:

1) Weigh the empty bowl and record.

2) Put the sealing ring on the bowl, and then hang the clamping ring on the frame of the bowl.

3) Fill the mortar with mortar and shake / compact it.

4) Open the seal ring and use a large hammer to make the mortar over the edge of the bowl.

5) Weigh the full bowl, then subtract the recorded empty bowl weight to calculate the density of the bulk cargo.

6) Now clean the edges of the bowl with a clean cloth.

7) Put the upper part on the cleaned bowl, then fasten the clamps around.

8) Open the stop valve with the control lever up. Then use a wash bottle to pour water into the stop valve until the water overflows from the stop valve without air bubbles.

9) Turn the semi-circular handle on the left to turn on the air pump until the pointer of the pressure gauge points to the distance "3 position below% AIR". Now slowly turn the screw of the exhaust valve to the left until the pointer of the pressure gauge accurately points to "3 position below% AIR". If you point to this position, turn the screw clockwise to close the exhaust valve. ("Position of 3 below% AIR" is also the initial pressure point, which has the same effect as the air content of concrete.)

10) Close the stop valve.

11) When the pointer returns to zero, detection starts. Press the joystick for about 20 seconds until the pointer of the pressure gauge no longer moves.

12) Read the percentage of gas content directly on the pressure gauge.

13) Slowly open the stop valve. Then turn the screw to the left to release the excess pressure.

14) Open the upper part, empty the bowl, then clean it up and dry all the parts [1]
