High Power And Ultrafast S&A Laser Chiller CWUP-40 ±0.1℃ Temperature Stability Test
Having watched the previous CWUP-40 Chiller Temperature Stability Test, a follower commented that it is not accurate enough and he suggested to test with scorching fire. S&A Chiller Engineers quickly accepted this good idea and arranged a “HOT TORREFY ” experience for the chiller CWUP-40 to test its ±0.1℃ temperature stability. First to prepare a cold plate and connect the chiller water inlet & outlet pipes to the cold plate’s pipelines. Turn on the chiller and set the water temperature at 25℃, then paste 2 thermometer probes on the water inlet and outlet of the cold plate, ignite the flame gun to scorch the cold plate. The chiller is working and the circulating water quickly takes away the heat from the cold plate. After 5-minute burning, the temperature of chiller inlet water rises to about 29℃ and can not go up anymore under the fire. After 10 seconds off the fire, the chiller inlet and outlet water temperature quickly drop to about 25℃, with temperature difference stable within the range of ±0.1℃. Clearly, even under high temperature “torrefy”, this chiller can still play its high-precise temperature control ability to full.
S&A Ultrafast Laser Chiller CWUP-40 Temperature Stability 0.1℃ Test
Recently, a laser processing enthusiast has bought the high-power and ultrafast S&A laser chiller CWUP-40. Having opened the package after its arrival, they unscrew the fixed brackets on the base to test whether the temperature stability of this chiller can reach ±0.1℃. The lad unscrews the water supply inlet cap and fills pure water to the range within the green area of the water level indicator. Open the electrical connecting box and connect the power cord, install the pipes to the water inlet and outlet port and connect them to a discarded coil. Put the coil in the water tank, place one temperature probe in the water tank, and paste the other to the connection between the chiller water outlet pipe and the coil water inlet port to detect the temperature difference between the cooling medium and chiller outlet water. Turn on the chiller and set the water temperature to 25℃. By changing the water temperature in the tank, the chiller temperature control ability can be tested. After pouring a large pot of boiling water into the tank, we can see the overall water temperature suddenly rises to about 30℃. The circulating water of the chiller cools the boiling water through the coil, since the water in the tank does not flow, the energy transfer is relatively slow. After a short period of effort by S&A CWUP-40, the water temperature in the tank finally stabilizes at 25.7℃. Only 0.1℃ difference from 25.6℃ of the coil inlet.Then the lad adds some ice cubes to the tank, the water temperature suddenly drops, and the chiller begins to control the temperature. Finally, the water temperature in the tank is controlled at 25.1℃, coil inlet water temperature maintains at 25.3℃. Under the influence of complex ambient temperature, this industrial chiller still shows its high-precision temperature control.
What causes the blurry marks of the laser marking machine?
What are the reasons for the blurred marking of the laser marking machine? There are three main reasons: (1) There are some problems with the software setting of the laser marker; (2) The hardware of the laser marker is working abnormally; (3) The laser marking chiller is not cooling properly.
The laser suddenly cracked in winter?
Maybe you forgot to add antifreeze. First, let’s see the performance requirement on antifreeze for chiller and compare various types of antifreeze on the market. Obviously, these 2 are more suitable. To add antifreeze, we must first understand the ratio. Generally, the more antifreeze you add, the lower the freezing point of water, and the less likely it is to freeze. But if you add too much, its antifreezing performance will decrease, and it is pretty corrosive. Your need to prepare the solution in proper proportion based on the winter temperature in your region.Take the 15000W fiber laser chiller as an example, the mixing ratio is 3:7(Antifreeze: Pure Water) when used in the region where the temperature is not lower than -15℃. First to take 1.5L of antifreeze in a container, then add 3.5L of pure water for 5L mixing solution. But the tank capacity of this chiller is about 200L, actually it needs around 60L antifreeze and 140L pure water to fill in after intensive mixing. Calculate and you will know whether adding antifreeze is more cost-effective than repairing the laser. Ensure the chiller is under power-off state, unscrew the water supply inlet cap, turn on the water drain tap, drain the residual water and turn off the water drain tap, pour the prepared mixing solution in the chiller. Antifreezing solution used for a long time will have certain deterioration and become more corrosive. Its viscosity will also change. Don’t forget to replace the mixing solution with pure water after cold weather gone.
How to improve the cooling efficiency of industrial chiller?
Industrial chiller can improve the working efficiency of many Industrial processing devices, but how to improve its cooling efficiency? The tips for you are: check the chiller daily, keep sufficient refrigerant, do routine maintenance, keep the room ventilated and dry, and check the connecting wires.
What kind of industrial chiller is configured for the inductively coupled plasma spectrometry generator?
Mr. Zhong wanted to equip his ICP spectrometry generator with an industrial water chiller. He preferred the industrial chiller CW 5200, but the chiller CW 6000 can better meet its cooling needs. Lastly, Mr. Zhong believed in the professional recommendation of the S&A engineer and selected a suitable industrial water chiller.
3000W Laser Welding Chiller Vibration Test
It is a huge challenge when S&A industrial chillers are subject to varying degrees of bumping in transit. To ensure product quality, every S&A chiller is vibration tested before being sold. Today, we will simulate the transportation vibration test of the 3000W laser welder chiller for you.Securing the chiller firm on the vibration platform, our S&A engineer comes to the operation platform, opens the power switch and sets the rotating speed to 150. We can see the platform slowly begins to generate reciprocating vibration. And the chiller body vibrates slightly, which simulates the vibration of a truck passing through a rough road slowly. When the rotating speed goes to 180, the chiller itself vibrates even more obviously, which simulates the truck accelerating to pass through a bumpy road. With the speed set to 210, the platform begins to move intensely, which simulates the truck speeding through the complex road surface. The chiller’s body jolts correspondingly. Apart from the detachable sheet metal dropping off, the juncture part of the metal sheet vibrates apparently. Violent vibration also causes visible movement of different parts, but the metal sheet shell remains strong and intact. And the chiller still works normally.Due to the strong vibration test intensity, the chiller will not re-enter the market. It will be used as an experimental machine for the R&D department to improve the chiller’s indexes, which helps S&A chiller users to use more premium products.
Precautions for the selection of industrial water chiller antifreeze
In some countries or regions, the temperature in winter will reach below 0°C, which will cause the industrial chiller cooling water to freeze and not operate normally. There are three principles for the use of chiller antifreeze and the selected chiller antifreeze should preferably have five characteristics.
Composition of industrial water chiller operating system
The industrial water chiller cools down the lasers through the working principle of circulating exchange cooling. Its operating system mainly includes a water circulation system, a refrigeration circulation system and an electrical automatic control system.
How to deal with water leakage of the industrial chiller’s drain port?
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.
The working principle of laser chiller
Laser chiller is composed of a compressor, a condenser, a throttling device (expansion valve or capillary tube), an evaporator and a water pump. After entering the equipment that needs to be cooled, the cooling water takes away the heat, heats up, returns to the laser chiller, and then cools it again and sends it back to the equipment.
How to check the room temperature and flow of industrial water chiller?
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 filter screen.
