乳化瀝青輪碾壓試驗(yàn)儀控制器的使用:

先連接控制器與主機(jī)上的電機(jī)線和傳感器線插頭將電源插頭插入三相四線制得插座中,打開(kāi)電源開(kāi)關(guān),數(shù)顯計(jì)數(shù)器顯示為1000次的工作狀態(tài),如按“SET"設(shè)定鍵計(jì)數(shù)器會(huì)轉(zhuǎn)換為100次工作狀態(tài),軟“Δ"或是“▽"鍵可將計(jì)數(shù)設(shè)定值任意改多或改少,設(shè)定值確定后,按“啟動(dòng)"鍵,主機(jī)將進(jìn)行工作。

The use of emulsified asphalt wheel rolling tester controller:

First connect the motor and sensor cable plugs on the controller and the host, insert the power plug into a three-phase four-wire socket, turn on the power switch, and the digital display counter displays the working state of 1000 times, such as pressing the "SET" setting key The counter will be switched to 100 working states. The soft "Δ" or "▽" key can be used to change the count setting value arbitrarily more or less. After the setting value is determined, press the "Start" key and the host will work.


乳化瀝青輪碾壓試驗(yàn)儀試驗(yàn)步驟:

★調(diào)節(jié)連接壁軸和腳輪之間的距離為61cm,輪子必須對(duì)中,保證輪子運(yùn)動(dòng)時(shí)框架保持平衡。

★將配重箱對(duì)中,保證心在輪軸的垂直方向。

★將清洗干凈的負(fù)荷輪放在臺(tái)秤上,這時(shí)連接臂要和框架平行。然后往配重箱加載,調(diào)節(jié)總重質(zhì)量為56.7kg。

★抬起輪子,把式樣對(duì)著定位銷(xiāo),安裝在儀器上,用元寶螺母夾緊。

★把負(fù)荷輪放在式樣上。開(kāi)動(dòng)儀器使輪子在試樣上往復(fù)碾壓1000次,碾壓的頻率為44次/min,在碾壓過(guò)程中如發(fā)現(xiàn)樣品上有出現(xiàn)發(fā)粘現(xiàn)象或明顯的發(fā)亮點(diǎn)時(shí),可撒少量水以防止輪子粘起樣品。

★碾壓1000次后停下儀器,卸載,取下試樣,用水把試樣表面沖洗干凈,放在60℃的烘箱中烘干至恒重。

★碾壓100次后停機(jī),取下試樣,用毛刷輕輕刷去試樣上的浮砂,然后稱試樣及吸附的砂子總質(zhì)量(M2)

Test procedure of emulsified asphalt wheel roller tester:

★ Adjust the distance between the connecting wall shaft and the caster to 61cm. The wheels must be centered to ensure that the frame is balanced when the wheels move.

★ Center the weight box to ensure that the center is in the vertical direction of the axle.

★ Place the cleaned load wheel on the platform scale. At this time, the connecting arm should be parallel to the frame. Then load it into the weight box and adjust the total weight to 56.7kg.

★ Raise the wheel, point the pattern to the positioning pin, install it on the instrument, and clamp it with ingot nuts.

★ Put the load wheel on the pattern. Start the instrument to make the wheel roll over the sample 1000 times, and the frequency of rolling is 44 times / min. If the sample is found to have stickiness or obvious bright spots during the rolling process, you can sprinkle a small amount of water Prevent the wheels from sticking to the sample.

★ After rolling 1,000 times, stop the instrument, unload, remove the sample, rinse the surface of the sample with water, and dry in a 60 ° C oven to constant weight.

★ Take out the sample from the oven and weigh it (M1), and immediately reinstall the sample in the original position of the instrument. Place the sand frame on the sample in the correct position, weigh 200g (82 ° C) of hot sand into the sand frame and quickly flatten it. Place the steel cover in the middle of the sand frame.

★ Put the load wheel on the steel cover. Operate the instrument 100 times at the same frequency.

★ Stop the machine after rolling 100 times, remove the sample, and gently brush the floating sand on the sample with a brush, and then weigh the total mass of the sample and the adsorbed sand (M2)
