LS-546砂浆含气量测定仪

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,砂浆含气量测定仪产品简介:
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。
First, the product introduction:
The mortar gas content measuring instrument is based on JGJ/T70-2009 (Building Mortar Basic Performance Test Method Standard) and JISA1228 specification for measuring the air content in the mortar. The measurement principle is based on the gas equation, between the gas chamber holding a certain pressure and the container filled with the sample, the opening and closing pressure is balanced, and when the pressure in the two containers reaches equilibrium, the amount of pressure in the gas chamber is reduced. The percentage that is shown on the pressure gauge is the air content in the sample.

二,砂浆含气量测定仪工作原理:
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 equation, between the air chamber holding a certain pressure and the container filled with the sample, when the pressure of the two containers is balanced, the pressure of the two chambers is reduced, that is, the amount of air in the mortar is occupied. The percentage indicated on the pressure gauge is the air content in the sample.

4、耐用且结构紧凑,A适合施工现场高频率使用。
5、轻小方便、一表多用、精度高等。全部硅合胶密封技术,使仪器局部可以单独启动密封作用。
Third, the instrument features:
1. Directly read the measured value of the gas content without drawing a curve, the operation is simple, and the reading value is accurate.
2, acid and alkali resistant metal materials, special sealing ring pads, waterproof, dustproof, explosion-proof pressure gauge.
3. Small size and light weight. Built-in hand pump for easy carrying.
4. Durable and compact, it is most suitable for high frequency use on the construction site.
5, light and convenient, a multi-purpose table, high precision. All silicone sealing technology enables the instrument to be individually activated for sealing.

四,砂浆含气量测定仪技术参数:

二,五,使用方法:
1、将拌好的混凝土分二次装入钵体,
2、分别振实,排除气泡,刮去表面多余部分,
3、盖上盖子,将压紧阀对衬均匀拧紧,关闭所有阀门。
4、用充气阀充气至――。点的位置,停3-5秒,
5、按动进气阀,表针所指的位置就是混凝土含气量的实测数值(红色)
6、测定完毕,缓慢的松动调压阀,
7、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, how to use:
1. The mixed concrete is sub-loaded into the carcass.
2, respectively, tapping, eliminating bubbles, scraping off the excess surface,
3. Cover the cover and tighten the pressure washer to the lining evenly to close all valves.
4, use the inflation valve to inflate to -. The position of the point, stop for 3-5 seconds,
5. Press the intake valve, the position indicated by the needle is the measured value of the concrete gas content (red)
6. After the measurement is completed, slowly loosen the pressure regulating valve.
7. Slowly return the needle to the zero point. Do not loosen it to prevent the pointer from hitting the zero positioning column, which will affect the accuracy.

六,砂浆含气量测定仪操作规程:
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”,也就是初压点,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 weight and record it.
2) Place the seal ring on the cymbal and hang the clamp ring onto the frame of the cymbal.
3) Fill the crucible with mortar and shake/compact it.
4) Uncover the sealing ring and use a large hammer to make the mortar exceed the edge of the crucible.
5) Weigh the weight of the full weight, then subtract the weight of the recorded empty space to calculate the density of the bulk cargo.
6) Now clean the edges of the file with a clean cloth.
7) Place the upper part on the cleaned cymbal and fasten the clamps around.
8) Open the stop valve and the lever is up. Then use a wash bottle to fill the stop valve with water until the water overflows from the stop valve and there are no air bubbles.
9) Turn the left semi-circular handle to open the air pump until the pointer of the pressure gauge points to the "3 position below %AIR". Now slowly screw the screw of the exhaust valve to the left until the pointer of the pressure gauge is accurately pointed to "3 position below %AIR". If you point to this position, turn the screw clockwise to close the exhaust valve. ("The position of 3 below the %AIR", which is the initial pressure point, has the same effect as the concrete gas content.)
10) Close the stop valve.
11) Start detection when the pointer is zeroed. Press the rocker for about 20 seconds until the pointer of the pressure gauge is no longer moving.
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, vacate the raft, then clean it up and dry all the parts [1]
