采用进口处理器,全自动控制仪器。

Third, the main features:
★ Double cylinder test to improve work efficiency.
★ High-frequency low-amplitude exhaust method, exhaust more thoroughly.
★ plexiglass container, imported sealing ring, no air leakage, no cracking.
★Using imported vacuum pump, there is no vacuum pump returning phenomenon.
★Using imported processor, fully automatic control instrument.

 

四,操作规程

打开 电源开关 按下 抽气/停止 仪器即开始工作,两只负压容器的真空度迅速下降,下降到97.3Kpa后,按下 抽气/停止 关闭真空泵。 恒压3分钟按下 间断/停止 开关,负压容器开始振荡。每隔2分钟振荡一次,每次振荡60秒,经过6次间歇.震荡后,仪器自动关闭 。

经振荡以后如果料中气体仍未全部除去,可按下 连续/停止 开关,进行人工控制仪器持续工作,直至气泡全部消失为止,按下 电源开关 结束试验。

自动试验中,如果观察到料中气泡已经除去,不需要再继续抽气和振荡下去,可以随时按下各个工作开关,停止试验工作。

Fourth, the operating procedures:
★ Turn on the power switch Press to pump/stop The instrument starts to work. The vacuum of the two negative pressure vessels drops rapidly. After dropping to 97.3Kpa, press the pump/stop to turn off the vacuum pump. Pressing the stop/stop switch for 3 minutes at a constant pressure, the negative pressure container begins to oscillate. It oscillates every 2 minutes, each time it oscillates for 60 seconds. After 6 times of shaking, the instrument automatically turns off.
★ If the gas in the material has not been completely removed after the oscillation, press the continuous/stop switch to manually control the instrument to continue working until the bubbles disappear. Press the power switch to end the test.
In the automatic test, if it is observed that the bubbles in the material have been removed, it is not necessary to continue pumping and oscillating. You can press each working switch at any time to stop the test.

 

五,注意事项:

拆开包装箱后,将仪器安装在干燥、通风及清洁场所,环境温度不能超过40℃。

每次试验前要检查放气阀是否关闭。检查仪器后部的分水滤气阀是否已积满水。要及时将积水放出(逆时针旋转手柄放水,顺时针将阀关紧)以免积水流入真空系统。

仪器连续工作两小时以后应停机一小时。

禁止将容器中的水滴入仪器。

非专业技术人员严禁拆卸仪器各部分的防护板。

Five, note:
★ After unpacking the box, install the instrument in a dry, ventilated and clean place. The ambient temperature should not exceed 40 °C.
★ Check that the bleed valve is closed before each test. Check that the water-separated filter valve at the rear of the instrument is full of water. It is necessary to release the accumulated water in time (rotate the handle counterclockwise and close the valve clockwise) to prevent the accumulated water from flowing into the vacuum system.
★ The instrument should be shut down for one hour after two hours of continuous operation.
★ Do not allow water droplets from the container to enter the instrument.
★ Non-professional technicians are strictly forbidden to disassemble the protective plates of all parts of the instrument.
