How to replace the cooling fan for CW-3000 chiller?First, turn off the chiller and unplug its power cord, uncap the water supply inlet, unscrew the fixing screws and remove the sheet metal, cut off the cable tie, distinguish the cooling fan’s wire and unplug it. Take away fixing clips on both sides of the fan, disconnect the fan’s ground wire, untighten the fixing screws to take out the fan from the side. Watch carefully the airfow direction when installing a new fan, don't install it backwards because the wind is blowing out of the chiller. Assemble the parts back the way you disassemble them. It is better to organize wires using a zip cable tie. Lastly, assemble the sheet metal back to finish.What else do you want to know about the maintenance of the chiller?

Try replacing the cooling fan capacitor of the industrial water chiller!First, remove the filter screen on both sides and the power box panel. Don't get it wrong, this is the compressor starting capacitance, which needs to be removed, and the hidden one inside is the starting capacitance of cooling fan. Open the trunking cover, follow capacitance wires then you can find the wiring part, use a screwdriver to unscrew the wiring terminal, the capacitance wire can be easily taken out. Then use a wrench to unscrew the fixing nut on the back of power box, after which you can take off the starting capacitance of the fan. Install the new one on the same position, and connect wire at the corresponding position in the junction box, tighten the screw and the installation is completed.Follow me for more tips on the chiller maintenance.

Mold is an indispensable component in modern industrial production. Sulfide, oil stain and rusty spots will form on the mold after long-term work, which will result in the burr, dimension instability, etc. of the produced products. The traditional methods of mold washing include mechanical, chemical, ultrasonic cleaning, etc., which are greatly restricted when meeting environmental protection and high precision application needs.Laser cleaning technology uses a high-energy laser beam to irradiate the surface, rendering the instantaneous evaporation or stripping of the surface dirt, causing high speed and effective dirt removal. It is a pollution-free, noiseless and harmless green cleaning technology. S&A chillers for fiber lasers provide laser cleaning equipment with a precise temperature control solution. Having 2 temperature control systems, suitable for different occasions. Real-time monitoring of chiller operation and modification of chiller parameters. Resolving mold dirt p...

In the fields of industry, energy, military, machinery, remanufacturing and others. Affected by the production environment and heavy service load, some important metal parts of may corrode and wear. To prolong the work life of the expensive manufacturing equipment, parts of the metal surface of the equipment need to be treated early or repaired. Through the synchronous powder feeding method, laser cladding technology helps deliver the powder to the matrix surface, using high-energy and high-density laser beams, to melt the powder and some matrix parts, helping to form a cladding layer on the surface with performance superior to that of the matrix material, and form a metallurgical bonding state with the matrix, so as to achieve the purpose of surface modification or repair.Compared with traditional surface processing technology, laser cladding technology features low dilution, with coating well bonded with the matrix, and great change in particle size and content. The laser claddin...

The industrialization of 10kW laser machines promotes the use of ultrahigh-power fiber laser cutting machines in the thick sheet metal processing field. Take the ship production as an example, demand is strict on the precision of the hull section assembly. Plasma cutting was often used for rib blanking. To ensure the assembly clearance, cutting allowance was first set on the rib panel, then manual cutting was made during on-site assembly, which increases the assembly workload, and prolongs the whole section construction period. 10kW+ fiber laser cutting machine can ensure high cutting precision, without leaving the cutting allowance, which can save materials, reduce redundant labor consumption and shorten the manufacturing cycle. 10kW laser cutting machine can realize high-speed cutting, with its heat affected zone smaller than that of the plasma cutter, which can solve the workpiece deformation problem. 10kW+ fiber lasers generate more heat than normal lasers, which is a severe tes...

What to do if the flow alarm rings in the industrial chiller CW 3000? 10 seconds to teach you to find the causes.Firstly, turn off the chiller, remove the sheet metal, unplug the water inlet pipe, and connect it to the water supply inlet. Turn on the chiller and touch the water pump, its vibration indicates the chiller works normally. Meanwhile, observe the water flow, if the water flow decreases, please immediately contact our after-sales staff.Follow me for more tips on the maintenance of chillers.

What to do if the cooling fan of the chiller CW-3000 does not work?This may be caused by the low ambient temperature. The low ambient temperature keeps the water temperature below 20 ℃, thus leading to its malfunction. You can add some warm water through the water supply inlet, then remove the sheet metal, find the wiring terminal beside the fan, then re-plug the terminal and check the operation of the cooling fan. If the fan is rotating normally, the fault is solved. If it still does not rotate, please immediately contact our after-sales staff.

During the operation of the chiller, the filter screen will accumulate a lot of impurities. When impurities accumulated too much in the filter screen, it will easily lead to a chiller flow decrease and a flow alarm. So it needs to inspect regularly and replace the filter screen of the Y-type filter of the high and low temperature water outlet.Turn off the chiller firstly when replacing the filter screen, and use an adjustable wrench to unscrew the Y-type filter of the high-temperature outlet and the low-temperature outlet respectively. Remove the filter screen from the filter, check the filter screen, and you need to replace the filter screen if there are too many impurities in it. Notes not losing the rubber pad after replacing the filter net and putting it back in the filter. Tighten with an adjustable wrench.

OLED is known as the third-generation display technology. Because of its lighter and thinner, low energy consumption, high brightness and good luminous efficiency, OLED technology is more and more widely used in electronic products and other fields. Its polymer material is particularly sensitive to thermal influences, the traditional film cutting process is no longer suitable for today's production needs, and now there are application requirements for special-shaped screens which are beyond the traditional craftsmanship capabilities. Ultrafast laser cutting came into being. It has minimum heat affected zone and distortion, can nonlinearly process various materials, etc. But ultrafast laser generates a lot of heat during processing and requires supporting cooling tools to control its temperature. Ultrafast laser requires higher temperature control accuracy. Temperature control accuracy of S&A CWUP series chillers up to ±0.1℃, can precise temperature control for ultrafast lasers a...
