The main parameters and precautions of the Zener diode!

Time of issue : 2021-07-19 19:14:00

The stable voltage is the working voltage of the Zener diode in the reverse breakdown zone, and the voltage value at both ends of the tube. This value changes slightly with the difference of operating current and temperature. Even for the same type of Zener diode, the stable voltage value has a certain degree of dispersion. For example, the stable voltage of 2CW14 silicon Zener diode is 6~7.5V.

Laser tube performance

Time of issue : 2021-07-19 19:02:00

Life: Because the laser tube is a consumable for the laser engraving machine, the life is the most important purchase index for users. The difference in life is mainly due to processing technology, and design technology is the main factor. Generally, the working life of domestic laser tube is about 1500 hours (60W as an example).

The structure of the laser tube

Time of issue : 2021-07-19 19:01:00

Hard glass part; this part is made of GG17 material fired into discharge tube, water cooling jacket, air storage jacket and return pipe. The sealed-off CO2 laser is usually a three-layer sleeve structure. The innermost is the discharge tube, the middle is the water purifier, the outermost layer is the gas storage sleeve, and the return gas pipe is used to connect the discharge tube and the gas storage tube.
