聯(lián)系我時，請告知來自 紡織服裝機械網(wǎng)虹吸筒,公路土工試驗儀器
虹吸筒適用于粒徑大于,等于5mm的土，且其中粒徑為20mm的土的含量大于，等于總土質(zhì)的10%。
The siphon cylinder gravimeter is suitable for soils having a particle diameter greater than or equal to 5 mm, and the content of the soil having a particle diameter of 20 mm is greater than or equal to 10% of the total soil quality.
虹吸筒技術(shù)參數(shù)：
★虹吸筒裝置，由虹吸筒和虹吸管組成。
★臺稱：稱量10Kg,A小分度值1g。
★量筒：容積應(yīng)大于2000mL 。
★外形尺寸：450mm
★重量:10kg
Siphon tube gravimeter technical parameters:
★Siphon tube device, consisting of a siphon tube and a siphon tube.
★ Taiwan scale: weighing 10Kg, A small division value of 1g.
★ Measuring cylinder: the volume should be greater than 2000mL.
★Dimensions: 450mm
★ Weight: 10kg
虹吸筒試驗進行步驟
★取代表性試樣試樣700-1000G,試樣應(yīng)清洗潔凈直至顆粒表面無塵土和其他污物。
★將試樣浸入水中一晝夜后取出晾干,對大顆粒試樣宜用干布擦干表面,并稱晾干試樣質(zhì)量。
★將清水注入虹吸筒至虹吸管口有水溢出時關(guān)管夾，
虹吸筒4將試樣緩緩放入虹吸筒中，邊放邊攪拌，至試樣中無氣泡逸出為止，攪動時水不得濺出筒外。
★當(dāng)虹吸筒內(nèi)水面平穩(wěn)時開管夾，讓試樣排開的水通過虹吸管流入量筒，稱量筒與水總質(zhì)量，準(zhǔn)確至0.5G,并測定量筒內(nèi)水溫,準(zhǔn)確到0.5 ℃.虹吸筒
★取出試樣烘至恒量、稱烘干試樣質(zhì)量，準(zhǔn)確至0.1G，稱量筒質(zhì)量，準(zhǔn)確至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
虹吸筒其他儀器：烘箱，溫度計，孔徑5mm及20mm的篩等。
Siphon tube gravimeter other instruments: oven, thermometer, sieve with aperture 5mm and 20mm.
