Laser marking machine pause with cold water

by:J&D WATER     2020-03-22
Cooling water machine for laser used in cooling cutting machine, marking machine, engraving machine, equipment such as ultraviolet laser, CO2 laser tube, semiconductor laser, rf CO2 laser tube, optical fiber laser. The user can according to different laser power matching for cold water machine. Cooling water machine for laser is a kind of individualized industrial refrigerating machine for laser industry applications, laser cold water machine mainly carried out on the laser equipment of laser generator cooling water circulation, and control the use of laser generator temperature, keep the laser generator can long time work. Laser equipment in the long running process, the laser generator will continue to produce high temperature, temperature too gao will affect the normal work of the laser generator, so need to cycle cooling water machine for laser cooling temperature control. For the type of laser generator, cold water machine classification, divides into the cooling water machine for laser co2 glass laser tube cold water machine, carbon dioxide laser metal rf tube side of cooling water machine for laser, semiconductor pump laser, semiconductor pump laser chillers, cold water machine YAG laser chiller machine, uv laser, optical fiber laser cold water chiller. Here to teach you how to selecting the cold water machine? A. Refrigerating capacity as the name suggests for laser water chiller refrigeration capacity, is the first type laser pause in cold water. An indicator. We can according to the photoelectric conversion efficiency of laser marking machine to calculate the calorific value of the laser marking machine, matching options. P = P laser heat/mu assumes that the thermal efficiency of CO2 laser marking machine mu is commonly 15%, 80 w laser is the least need: 80/0. 15 = 533 w that is to say, at the same time of producing 80 w laser, laser injection 533 w of energy, away excess energy need cooling water machine for laser. We directly according to the laser power supply of rated power input minus the laser output power to determine the refrigerating capacity of the cooling water machine for laser. Such as we often use radio frequency laser and solid laser can indicate the full power of the power supply voltage and rated current, rf laser coherent 70 w, for example, the required power input 48 v25a, instantaneous 36 a, the input power can be calculated. 1200 w. 2. Hm pump pressure and rate of water flow everyone will focus on the refrigerating capacity of the cooling water machine for laser, tend to ignore the pump hm the indicators. Refrigerating capacity on behalf of the compressor but provide refrigeration capacity and water flow on behalf of the ability to take away heat, cold water machine which you often see the phenomenon: in the name of the refrigerating capacity of 1000 w cold water machine connected to a 80 w glass tube, cold water machine according to 25 ℃, laser tube is hot, this is because the pump pressure is not high, hm water didn't have enough pressure to push the water cycle, heat is taken away. 3. Water filter and water quality requirements and tank material this composite indicator is often neglected, but its very reuse, directly affect the service life of laser. For CO2 laser tube, both ends of the lens out of the corner belongs to water, it is easy to stop the impurities in the water, due to poor heat dissipation, lens of micro deformation directly affect the output of laser beam quality and speckle pattern. For radio frequency laser cooling plate gathered impurities such as scale and the rust will cause cavity temperature electric plate deformation, and the temperature sensor alarm, laser out of fault to produce light. For YAG laser pumped light, crystal and gilded cavity surface cleanliness directly influence the light power and light spot pattern; Tiny hole plug directly inside the semiconductor module article will burn. On the market are mostly cold water machine the refrigerant tube adopts copper pipe, and directly put in cooling water evaporation pan, can produce a large number of the rust, directly affect the laser. A lot of no filter is cold water machine directly with water or use a long time not to replace the pure water, can make the breeding of bacteria and impurity deposition to the laser, affect the service life of laser and using effect. So we have to check the water quality situation in the water tank, regular replacement of water and cleaning water tank, keep the water clear and clean. For water tank equipped with a water filter, filter the impurities in the water.
