虹吸筒试验进行步骤

取代表性试样试样700-1000G,试样应清洗洁净直至颗粒表面无尘土和其他污物。

将试样浸入水中一昼夜后取出晾干,对大颗粒试样宜用干布擦干表面,并称晾干试样质量。

将清水注入虹吸筒至虹吸管口有水溢出时关管夹,

虹吸筒4将试样缓缓放入虹吸筒中,边放边搅拌,至试样中无气泡逸出为止,搅动时水不得溅出筒外。

当虹吸筒内水面平稳时开管夹,让试样排开的水通过虹吸管流入量筒,称量筒与水总质量,准确至0.5G,并测定量筒内水温,准确到0.5 ℃.虹吸筒

取出试样烘至恒量、称烘干试样质量,准确至0.1G,称量筒质量,准确至0.5G

Siphon tube gravimeter test steps
★ Take a representative sample of 700-1000G, the sample should be cleaned until the surface of the particles is free of dust and other contaminants.
★ Immerse the sample in water for a whole day and then take it out to dry. For large particle samples, dry the surface with a dry cloth and weigh the sample.
★Inject the clean water into the siphon tube until the siphon tube has water overflow.
The siphon cylinder 4 slowly puts the sample into the siphon cylinder, and while stirring, until no air bubbles escape from the sample, the water should not splash out of the cylinder when stirring.
★ When the water surface in the siphon cylinder is stable, open the pipe clamp, let the water discharged from the sample flow into the measuring cylinder through the siphon, weigh the cylinder and the total mass of the water to the nearest 0.5G, and measure the water temperature inside the measuring cylinder to the accuracy of 0.5 °C.
★ Take out the sample and bake it to a constant amount, say the quality of the dried sample, accurate to 0.1G, weighing the cylinder, accurate to 0.5G
