This video will teach you how to replace the DC pump of S&A industrial chiller 5200.First to turn off the chiller, unplug the power cord, uncap the water supply inlet, remove the upper sheet metal housing, open the drain valve and drain water out of the chiller, disconnect the DC pump terminal, use a 7mm wrench and a cross screwdriver, unscrew the 4 fixing nuts of the pump, remove the insulated foam, cut off the zip cable tie of the water inlet pipe, unfasten the plastic hose clip of the water outlet pipe, separate water inlet and outlet pipes from the pump, take out the old water pump and install a new pump on the same position, connect the water pipes to the new pump, clamp the water outlet pipe with a plastic hose clip, tighten 4 fixing nuts for the water pump base. Lastly, connect the pump wire terminal, and the DC pump replacement is finally finished.

What is ultrafast laser processing? Ultrafast laser is a pulse laser with pulse width of picosecond level and below. 1 picosecond is equal to 10⁻¹² of a second, the speed of light in air is 3 X 10⁸m/s, and it takes about 1.3 seconds for light to travel from the Earth to the Moon. During the 1-picosecond time, the distance of light motion is 0.3mm. A pulse laser is emitted in such a short time that the interaction time between ultrafast laser and materials is also short. Compared with traditional laser processing, the heat effect of ultrafast laser processing is relatively small, so ultrafast laser processing is mainly used in fine drilling, cutting, engraving surface treatment of hard and brittle materials such as sapphire, glass, diamond, semiconductor, ceramics, silicone, etc.The high-precision processing of ultrafast laser equipment needs a high-precision chiller to cool. S&A high-power & ultrafast laser chiller, with temperature control stability of up to ±0.1℃, can prov...

Chip is the core technological product in the information era. It was born of a grain of sand. The semiconductor material used in the chip is monocrystalline silicon and the core component of sand is silicon dioxide. Going through the silicon smelting, purification, high temperature shaping and rotary stretching, sand becomes the monocrystalline silicon rod, and after cutting, grinding, slicing, chamfering and polishing, silicon wafer is finally made. Silicon wafer is the basic material for semiconductor chip manufacture. To meet the requirements of quality control and process improvement and facilitate the management and tracking of wafers in subsequent manufacturing testing and packaging processes, specific marks such as clear characters or QR codes can be engraved on the surface of the wafer or crystal particle. Laser marking uses high-energy beam to irradiate wafer in a non-contact way. While executing the engraving instruction quickly, the laser equipment also needs to be coole...

What to do if the laser circuit’s flow alarm rings? First, you can press the up or down key to check the flow rate of the laser circuit. Alarm will be triggered when the value falls below 8, it may be caused by the Y-type filter clogging of the laser circuit water outlet.Turn off the chiller, find the Y-type filter of the laser circuit water outlet, use an adjustable wrench to remove the plug anticlockwise, take out the filter screen, clean and install it back, remember not to lose the white sealing ring on the plug. Tighten the plug with wrench, if the flow rate of laser circuit is 0, it is possible that the pump is not working or the flow sensor fails. Open the left-side filter gauze, use a tissue to check whether the back of the pump will aspirate, if the tissue is sucked in, it means the pump is working normally, and there may be something wrong with the flow sensor, feel free to contact our after-sales team to solve it. If pump is not working properly, open the electric box, me...

Having closed the chiller’s water drain valve, but the water still keeps running at midnight...Water leakage still occurs after the chiller drain valve is closed.This may be that the valve core of the mini valve is loose.Prepare an allen key, aiming at the valve core and tighten it clockwise, then check the water drain port. No water leakage means the problem is solved. If not, please contact our after-sales team immediately.

First to turn off the laser chiller, unplug the power cord, uncap the water supply inlet, remove the upper sheet metal housing, find and disconnect the flow switch terminal, use a cross screwdriver to remove the 4 screws on the flow switch, take out the flow switch top cap and the internal impeller. For the new flow switch, use the same method to remove its top cap and impeller. then install the new impeller into the original flow switch. Use the cross screwdriver to tighten the 4 fixing screws, reconnect the wire terminal and you’re done~Follow me for more tips on chiller maintenance.

Room temperature and flow are two factors that greatly affect the industrial chiller cooling capacity. Ultrahigh room temperature and ultralow flow will affect the chiller cooling capacity. The chiller works at room temperature above 40 ℃ for a long time will cause damage to the parts. So we need to observe these two parameters in real time.First, when the chiller is turned on, take the T-607 temperature controller as an example, press the right arrow button on the controller, and enter the status display menu. "T1" represents the temperature of the room temperature probe, when the room temperature is too high, the room temperature alarm will set off. Remember to clean up the dust to improve ambient ventilation. Continue to press the "►" button, "T2" represents the flow of the laser circuit. Press the button again, "T3" represents the flow of the optics circuit. When detected a traffic drop, the flow alarm will set off. It is time to replace the circulating water, and clean the filt...

The main function of the industrial chiller heater is to keep the water temperature constant and prevent cooling water from freezing. When the cooling water temperature is lower than the set one by 0.1℃, the heater starts to work. But when the heater of the laser chiller fails, do you know how to replace it?First, turn off the chiller, unplug its power cord, uncap the water supply inlet, remove the sheet metal casing, and find and unplug the heater terminal. Loosen the nut with a wrench and take out the heater. Take down its nut and rubber plug, and reinstall them on the new heater. Lastly, insert the heater back into the original place, tighten the nut and connect the heater wire to finish.
