测试目的:以(1/4”(6mm))钢球来测试眼镜(尤其是保护镜)的镜片强度,焊接点、镜框
与镜片密合等耐冲击测试。
使用说明:
1.首先请注意机台之电压为几伏特(V),然后找相同电压之插座将机台之插头插上。
2.将压力送上。
3.将氮气之高压调整阀装于氮气筒上, 再将机台后方之氮气高压管接于氮气筒。
4.打开银幕之电源,空气压力调至5kg,待屏幕归零后即可。
A.
选择高速或低速测试:
如欲选择高速:
1.先确认好第3 项歩骤之动作。
2.将高低速选择开关转向氮气高速测试。
3.打开氮气。
4.然后高速测试的压力则从氮气筒上的高压调整阀调整,压力大小则看面板的高
速调整压力表。
5.若停止测试将氮气关掉后,再按发射钮将氮气排出。
B.如欲选择低速:
1.将氮气关掉。
2.按发射钮,将机台内剩余的氮气排出。
(此1、2 项为高速切换低速时之前置歩骤;若直接测试低速则歩骤从第3 项开始)
3.然后将高低速选择开关转向空气低速测试。而压力调整则从操作面板右侧前方
有一只低速调整阀调整,压力大小则看操作面板之低速调整压力表。
4.
若停止测试将空气关掉后,再按发射钮将空气排出。
5.将雷射开关开啓,然后把射击箱内之人头移至非射击点之位置,在测速时不让钢珠打到,
或者可将人头座取出,再调整其所需之速度。
6.在调整速度或测试时,将钢珠上膛后,此时镭射光是不亮的(代表钢珠已上膛)再作发射
的动作。
7.
将弹珠装入弹孔内, 然后将上膛把手往后拉到底, 再放掉把手即可发射。
(※注意:若上膛把手未拉到底,则不能发射。)
(※因为**上之顾虑,所以射击箱门内装有一个**开关,因此门一开就不能发射弹
珠。)
完成以上动作后,即可将要测试之眼镜,戴上将要测试之人头上,然后调整其将要测试
之位置即可。(※注意:枪管上的电线(光纤)内心是玻璃材料,不可拉扯或扭曲,否则容
易断裂,就测不出时速。)
(以EN166标准为例)
冲击测试要求:眼睛保护

The purpose of the test: (1/4) (6mm) to test the glasses (especially the protective lens) lens strength, welding point, frame
Impact resistance test with lens.
Instructions:
1 first of all, please note that the voltage of the machine is a few volts (V), and then find the same voltage plug plug the machine.
2 put pressure on.
3 the nitrogen pressure regulating valve is installed on the nitrogen pump, and then the nitrogen pressure pipe in the rear of the machine is connected with the nitrogen pump.
4 open screen power supply, air pressure to 5kg, after the screen to zero.
A. select high speed or low speed test:
If you want to choose high-speed:
1 first confirm the third step.
2 turn the high and low speed selector switch to the nitrogen high speed test.
3 open nitrogen.
4 then the pressure of the high speed test is adjusted from the high pressure regulating valve on the nitrogen cylinder, and the pressure is high
Quick adjustment pressure gauge.
5 if the test will be turned off after the nitrogen, then press the launch button to discharge nitrogen.
B. if you want to choose low speed:
1 turn off nitrogen.
2 press the launch button, the machine will be the residual nitrogen.
(the 1, 2 for high speed switching speed of the front step; if the test is low step from third onwards)
3 then the high and low speed selector switch to the air at low speed test. Pressure adjustment from the front side of the operation panel
There is a low speed adjustment valve, the pressure of the operating panel to see the low speed adjustment pressure gauge.
4 if the test is stopped, the air will be discharged by the launch button.
5 turn on the laser switch, and then the head of the shooting box moved to the location of non firing points, in the speed of the ball will not hit,
Or can be taken out of the seat, and then adjust the speed required.
6 in the speed of adjustment or test, the steel ball is loaded, the laser light is not bright (on behalf of the steel ball is loaded before launch)
Action.
7 marbles into bullet holes, and then loaded the handle back end, then let go the handle can be fired.
(please note: if the handle is not loaded back, cannot launch. )
But because of security concerns, (so shooting inside the box door is provided with a safety switch, so the door opened cannot launch
Zhuhai. )
After the completion of the above action, you will be able to test the glasses, Dai will be tested on the head, and then adjust it will be tested
Position can. (Note: the barrel of the wire (fiber) is the heart of glass material, do not pull or twist or let Korah.
Easy to break, can not measure the speed. )
(EN166 standard as an example)
Impact test requirements: eye protection
Steel ball impact speed
Low speed impact: 148-153ft/s
Medium speed impact: 394-404 ft/s
High speed impact: 623-640 ft ft /s
