測試目的:以(1/4”(6mm))鋼球來測試眼鏡(尤其是保護鏡)的鏡片強度,焊接點、鏡框
與鏡片密合等耐沖擊測試。
使用說明:
1.首先請注意機臺之電壓為幾伏特(V),然后找相同電壓之插座將機臺之插頭插上。
2.將壓力送上。
3.將氮氣之高壓調(diào)整閥裝于氮氣筒上, 再將機臺后方之氮氣高壓管接于氮氣筒。
4.打開銀幕之電源,空氣壓力調(diào)至5kg,待屏幕歸零后即可。
A.
選擇高速或低速測試:
如欲選擇高速:
1.先確認好第3 項歩驟之動作。
2.將高低速選擇開關轉(zhuǎn)向氮氣高速測試。
3.打開氮氣。
4.然后高速測試的壓力則從氮氣筒上的高壓調(diào)整閥調(diào)整,壓力大小則看面板的高
速調(diào)整壓力表。
5.若停止測試將氮氣關掉后,再按發(fā)射鈕將氮氣排出。
B.如欲選擇低速:
1.將氮氣關掉。
2.按發(fā)射鈕,將機臺內(nèi)剩余的氮氣排出。
(此1、2 項為高速切換低速時之前置歩驟;若直接測試低速則歩驟從第3 項開始)
3.然后將高低速選擇開關轉(zhuǎn)向空氣低速測試。而壓力調(diào)整則從操作面板右側前方
有一只低速調(diào)整閥調(diào)整,壓力大小則看操作面板之低速調(diào)整壓力表。
4.
若停止測試將空氣關掉后,再按發(fā)射鈕將空氣排出。
5.將雷射開關開啓,然后把射擊箱內(nèi)之人頭移至非射擊點之位置,在測速時不讓鋼珠打到,
或者可將人頭座取出,再調(diào)整其所需之速度。
6.在調(diào)整速度或測試時,將鋼珠上膛后,此時鐳射光是不亮的(代表鋼珠已上膛)再作發(fā)射
的動作。
7.
將彈珠裝入彈孔內(nèi), 然后將上膛把手往后拉到底, 再放掉把手即可發(fā)射。
(※注意:若上膛把手未拉到底,則不能發(fā)射。)
(※因為**上之顧慮,所以射擊箱門內(nèi)裝有一個**開關,因此門一開就不能發(fā)射彈
珠。)
完成以上動作后,即可將要測試之眼鏡,戴上將要測試之人頭上,然后調(diào)整其將要測試
之位置即可。(※注意:槍管上的電線(光纖)內(nèi)心是玻璃材料,不可拉扯或扭曲,否則容
易斷裂,就測不出時速。)
(以EN166標準為例)
沖擊測試要求:眼睛保護
用品類型:鋼球沖擊速度

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
