Low-temperature thermostats are widely used and have certain applications in petroleum, chemical, biological engineering, medical and other fields. The low-temperature thermostat will also cause certain failures during use, which will affect the normal use of the equipment. Today we will specifically introduce the common faults and treatment methods of the low-temperature thermostat, hoping to help everyone.
1. When the low temperature thermostat is running for the first time, the instrument does not heat or cool. What's wrong?
Low-temperature thermostatic baths generally use a compressor that integrates heating and cooling, which can avoid multiple operations of the instrument program and extend the heating and cooling time. The instrument is generally equipped with heating and cooling insurance. Generally, the instrument does not heat or cool. , You can first check whether the heating or cooling fuse of the instrument is loose. If there is no looseness, you can unscrew the condom to check whether the fuse is burned out. If the fuse is replaced in time, the instrument can operate normally.
2. The low-temperature thermostat has been used for more than a year, and the cooling speed is getting slower and slower?
Answer: It seems that many of the defects and failures of the low-temperature thermostat are caused by the lack of regular maintenance. The electric power of the low-temperature thermostat water cycle and the heat taken away by the refrigerant from the load need to be drained from the radiator at the front hood. If the front hood is full of dust and willow cotton, it will hinder the dissipation of these heat. The cooling effect will be greatly reduced. Generally speaking, the decrease in cooling capacity under normal use conditions is caused by poor ventilation and heat dissipation or too high ambient temperature. There is also timely maintenance of the tank. If it is not used for a long time, it should be cleaned in time and kept dry.
3. The water cycle used to be normal, but now it is found that the noise is much louder than before?
Answer: This question is also related to the water circulation in the cryostat. Everyone knows that there are very few impurities in the water, even if distilled water is added to the water tank, it is impossible to guarantee that there are no impurities at all. For the water cycle, the general temperature is set at 20°C, which is particularly suitable for the growth and reproduction of microorganisms. After a long time, these microorganisms will block the filter of the waterway and cause the water return to be poor, and the pump will have a lot of noise. Sometimes these microorganisms are attached to the surface of the heat exchanger, causing the heat transfer effect of the heat exchanger to deteriorate and the cooling capacity to decrease. So do routine maintenance work, clean the inner tank regularly, and keep it out of use for a long time to keep the tank dry. For daily cleaning and precautions, please refer to the precautions of the cryostat.
4. Air leaks outside the low-temperature thermostat tank, sometimes there are a few drops on the ground for a while, is there a leak in the waterway?
Generally speaking, all interfaces in the process of instrument transfer are sealed with high-strength glue, so there will be no leakage in the waterway. But sometimes when the ambient temperature is relatively high, the relative humidity in the air is too high, due to low temperature operation, the water pump, water pipe joints, and external water pipes in the water circuit of the water circulation are prone to condensate dew, and when it accumulates, it will drip to the ground. , It is not a water leak, so you can use it with confidence. If you feel that this operation is not very safe, you can turn on the air conditioner to lower the indoor temperature.
