洛杉矶磨耗试验机调试与安装:

启动前首先检查旋转部分与料筒是否有刮碰现象,应及时调整。

减速箱应注入机油后方能使用,卸料蜗轮会及滑动轴承处注入机油。

清理料筒内染料。洛杉矶搁板式磨耗试验机

启动前将筒体限装置锁紧,然后再启动。

启开后发现运转方向不符合要求时,应切断电源,将导线的任意两根相线互换位置,再重新启动。

根据磨耗时间调整时间继电器的定时,注意在断电情况下调整。

按动启动按钮。

达到调定时间后自动停车。

卸料时先停机,然后将筒体位限置手柄松开,再旋转手轮,由蜗轮付带料筒旋转到便于出料的位置,停止转动,然后启动机器使主轴运转方可排出物料,直至将料排出停止,主轴运转旋转手轮使料筒复位。洛杉矶搁板式磨耗试验机

清洗料筒,将水倒入料筒内使主轴运转将料筒和铲片冲洗干净或用砂子清洗也可。

Los Angeles Abrasion Instrument Commissioning and Installation:
★ Before starting, first check whether the rotating part and the barrel are scratched, and adjust it in time.
★The gearbox should be used after the oil is injected. The unloading worm gear and the sliding bearing are filled with oil.
★ Clean the dye in the barrel. Los Angeles Shelf Abrasion Tester
★ Lock the cylinder limit device before starting, then start again.
★When starting and found that the running direction does not meet the requirements, the power should be cut off, and any two phase wires of the wire should be swapped and restarted.
★ Adjust the timing of the time relay according to the wear time, and pay attention to the adjustment in case of power failure.
★Press the start button.
★Automatic stop after reaching the set time.
★ Stop the machine first, then release the handle of the cylinder limit, then rotate the handwheel. The worm wheel rotates the barrel to the position where it is easy to discharge, stops the rotation, and then starts the machine to make the spindle run out. Until the discharge of the material is stopped, the spindle rotates the handwheel to reset the cylinder. Los Angeles Shelf Abrasion Tester
★ Clean the barrel, pour the water into the barrel to make the spindle run. Rinse the barrel and shovel or wash it with sand.

 

洛杉矶磨耗试验机使用方法:

试车前必须检查线路是否完好,(输入电源必须为三火)按点动键,滚筒旋转是否正常(按筒上箭头方向,如果转动方向相反,把输入380V中两相火线调换即改变)同时将LED显示屏清零再把予置拨码开关调到所试验次数,按启动键开始工作,如有特殊情况请按“暂停”键,机器停止工作,待故障排除后再次按“启动”键机器恢复工作.

将试验的碎石料和钢球装入筒内,密封盖好,拧紧螺钉,开动仪器转动500转或1000转后自动停止。此时出料口在中上位置,便于打开密封盖,打开盖后,按点动键,使出料口转向下方,松开按键试筒停止,取出试件。

用直径2mm圆孔筛或边长1.7mm方孔筛,筛去试样中的石屑,用水冲洗留在筛上的碎石,烘干、恒重,准确称出重量。

How to use the Los Angeles wearer:
★ Before the test, you must check whether the line is intact. (The input power must be three fires.) Press the jog key to check whether the drum rotation is normal. (Press the direction of the arrow on the cylinder. If the rotation direction is opposite, change the two-phase fire line in the input 380V to change) Clear the LED display and then adjust the preset DIP switch to the number of tests. Press the start button to start working. If there are special circumstances, please press the “Pause” button, the machine stops working. Press the “Start” button again after troubleshooting. The machine resumes work.
★ Put the crushed stone and steel ball into the cylinder, seal the cover, tighten the screw, and start the instrument automatically after 500 or 1000 revolutions. At this time, the discharge port is in the upper middle position, which is convenient to open the sealing cover. After opening the cover, press the jog key to make the discharge port turn downward, release the button test tube to stop, and take out the test piece.
★ Use a 2mm diameter circular sieve or a 1.7mm square hole sieve to remove the stone chips from the sample, rinse the gravel left on the sieve with water, dry and constant weight, and accurately weigh the weight.

 

洛杉矶磨耗试验机计算方法:

按下列计算石料磨耗率精确至0.1% Q磨=(G1-G2)/G1×100% 式中:Q磨--石料的磨耗率% G1--装入筒中碎石之原重量g G2--试验后,洗净烘干之重量g

试验结果两次试验之平均值,两次误差不大于2%否则重新试验。

Los Angeles wear meter calculation method:
★ Calculate the stone wear rate to 0.1% according to the following Q grinding = (G1-G2) / G1 × 100% Where: Q grinding - stone wear rate % G1-- the original weight of gravel loaded into the cylinder g G2- - after the test, the weight of the washing and drying g
★ Test results The average of two tests, the two errors are not more than 2% or the test is repeated.
