三、工作原理:

★该仪器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。

★直读式CA砂浆含气量测定仪是根据《客运专线铁路CRTSⅡ型板式无砟轨道水泥乳化沥青砂浆暂行技术条件》用于测量砂浆中的空气含量的仪器。

Third, the working principle:

★ The measuring principle of this instrument is based on the gaseous 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 mortar. The percentage of air content in the sample is indicated on the pressure gauge.

★ Direct-reading CA mortar gas content measuring instrument is an instrument for measuring the air content in mortar according to "Temporary Technical Conditions for CRTSⅡ Slab Ballastless Track Cement Emulsified Asphalt Mortar for Passenger Dedicated Railways".


四、操作规程:

★用湿布将量钵和盖的内表面擦净,然后装入砼试样,用振动式或插捣器抹平,直至无气泡.

★抹平后随后称出容器和砼试样的总质量。

★在正对操作阀孔的砼表面贴一小块薄纸或塑料薄膜,擦净法兰盘,盖好量钵盖,拧紧钳式夹,打开排气阀。

★关闭操作阀,从进气阀来压缩空气,使压力指针为1Kgf/cm2。

★关紧操作阀打开进水阀加少量水,关闭进水阀、排气阀使之密封不漏气。

★打开操作阀,使气室内的压缩溶器进入量钵,待压力表指针稳定后,读出表值。

Four, operating procedures:

★ Wipe the inner surface of the measuring bowl and lid with a damp cloth, then load the 砼 sample, and smooth it with a vibration or tamper until there are no air bubbles.

★ The total mass of the container and the tritium sample is then weighed after smoothing.

★ Paste a small piece of thin paper or plastic film on the surface of the diaphragm facing the operation valve hole, clean the flange, cover the measuring bowl cover, tighten the clamp clamp, and open the exhaust valve.

★ Close the operation valve and compress the air from the inlet valve to make the pressure pointer 1Kgf / cm2.

★ Close the operation valve, open the water inlet valve and add a small amount of water, and close the water inlet valve and exhaust valve to make it airtight.

★ Open the operation valve, make the compression vessel in the gas chamber enter the measuring bowl, and after the pressure gauge pointer stabilizes, read the gauge value.


五、特点:

★量钵采用铝合金耐酸碱材料精密铸造,结构严谨,容积准确,确保直读测定值的**度。

★直接读出所测定混凝土的含气量,操作简单方便,数值准确,减少了繁琐的绘制含气量与压力表值关系的曲线,省时省力。

★采用精制仪器装置压力表,安全性能好,刻度盘清晰直观。

★各部位的密封圈采用特种密封材料,密闭性能好,经久耐用,使用寿命长。

★内置手泵轻巧省时省力。

★注水式测定,无注水式测定兼用。

★体积小重量轻,便于携带,适于现场高频连续使用。

Five, characteristics:

★ The measuring bowl is precision cast with aluminum alloy acid and alkali resistant material. The structure is rigorous and the volume is accurate to ensure the reading of the measured value.

★ Directly read out the measured gas content of concrete, the operation is simple and convenient, and the value is accurate, which reduces the tedious drawing of the relationship between the gas content and the pressure gauge value, saving time and effort.

★ Using the refined instrument and device pressure gauge, the safety performance is good, and the dial is clear and intuitive.

★ The sealing ring of each part is made of special sealing material, which has good sealing performance, durability and long service life.

★ The built-in hand pump is light and time-saving.

★ Water injection type measurement, no water injection type measurement.

★ Small size and light weight, easy to carry, suitable for high frequency continuous use on site.
