pump screen

ZYLD ⅱ automatic filter presses increases a new electric current sensor, current collected module and crystal screen. The parameters ( pump time; press time and blow air time) can be reset according to slurry density.

ZYLDⅡ型自动压滤机新增设了电流传感器、电流采集模块和液晶触摸屏，实现了脱水工艺参数&进料时间、压榨时间、吹气时间可以随工况条件变化随时调整；

The results indicate that the type-ⅰ phase-matched NPS ring is centrosymmetric with respect to the pump beam on the observation screen.

结果表明，Ⅰ类非共线相位匹配的参量超荧光关于抽运光中心对称。

Shield repair kit to replace the pump screen and the special nature of the difficulties is to ensure the quality of repair shielding critical pump.

更换屏蔽套是修复屏蔽泵的难点和特殊之处，是保证修复屏蔽泵质量的关键。
