Why does the UV Accelerated Weathering Tester not drain properly?

2022-04-26 11:09

The spray effect of the UV aging tester can better imitate the real environmental conditions of the product when it is in use. When using pure water, the equipment needs to be drained normally after the test. Of course, during this process, we may encounter the situation that the water can not be drained normally. The following Gaotian test equipment editor will share the UV Accelerated Weathering Tester that cannot be drained normally. Solution.

Solution for UV Accelerated Weathering Tester not draining properly:

1. If the resistance value of the pump is normal, it is possible that impurities such as iron filings are sucked into the pump body. Please disassemble the pump body of the magnetic pump according to the method on the machine, clean it and then put it back to check whether it is normal. If it is still abnormal , please replace the magnetic pump.

2. Check whether the water pump is damaged, remove the two wires of the water pump, put the multimeter on the resistance gear, and measure the resistance of the pump. If the pump resistance is normal, the normal resistance value is 1060 euros. If the circuit is open or the resistance value is too low, the pump is damaged and needs to be replaced.


3. The UV Accelerated Weathering Tester heating tube is made of stainless steel tube filled with magnesium powder. If the user uses tap water without authorization to save a small cost and does not use deionized water as required, the heating tube will be soaked in tap water at high temperature for a long time, which will cause The stainless steel on the surface of the heating tube is corroded and rusted, which is not cost-effective because of the small loss.

The reasons why the UV Accelerated Weathering Tester cannot drain normally and the solutions are roughly the above points, I hope it can help you. The UV Accelerated Weathering Tester conducts the test by exposing the sample to be tested in a controlled alternating cycle of sunlight and moisture while increasing the temperature.
