The low temperature coolant circulation pump is a low temperature liquid circulation device that uses mechanical cooling.
It has the function of providing a low temperature liquid bath and a low temperature water bath.
Combined with a rotary evaporator, a vacuum freeze-drying box, a circulating water vacuum pump, a magnetic stirrer and other instruments, multifunctional chemical reaction operations and low temperature drug storage can be carried out.
Low temperature coolant circulation pump failure analysis:
The cooling speed seems to be getting slower and slower, and the higher the temperature, the slower It is more obvious ?
The low temperature coolant circulation pump is very easy to use, but regular maintenance cannot be ignored.
There are many problems that look like errorsbut in reality they are due to a lack of regular maintenance.
Both the electrical power of the low-temperature refrigerant circulation pump and the heat that the refrigerant removes from the charge must be dissipated by the radiator on the front ventilation hood;
< br /> If the front ventilation hood is filled with dust and wicker wool, it will hinder heat dissipation and the cooling effect will be greatly reduced.
Generally, the decline in cooling performance under normal usage conditions is caused by poor ventilation and heat dissipation effects or excessive ambient temperature.
When using the low temperature coolant circulation pump, I found that the noise was much louder than before
I mentioned the daily maintenance of the pump -temperature the coolant circulation pump. This problem is also related to this.
As we all know, water contains very few Verimpurities. Even if distilled water is added to the water tank, it cannot be completely guaranteed that there will be no impurities at all.
For the water circulation of the low temperature coolant circulation pump, the general temperature is set at 20°C, which is particularly suitable for the growth and reproduction of microorganisms.
Over time, these microorganisms clog the waterway filter, resulting in poor water return and the water pump making loud noises.
Sometimes these microorganisms attach to the surface of the heat exchanger, which deteriorates the heat transfer effect of the heat exchanger and reduces the cooling performance.
Therefore, you must carefully follow the instructions in the daily maintenance manual, clean the inner tank regularly, and keep the tank dry when not in use for a long time.
