Common problems with cryostats:
1. Aging phenomenon of machine parts
Machine performance:
The cooling rate is getting slower and slower to answer the question:
Check that the device exhaust and radiator are working properly!
The water circulation in the low temperature constant temperature tank is simple to use, and it is essential to do regular maintenance and maintenance work on a daily basis. Many common faults of precision instruments are caused by the usual maintenance work. The electric power of the water circulation and the heat taken away by the refrigerant from the load need to be discharged from the radiator at the front hood. If the front hood is filled with dust and sponge, it will hinder the heat dissipation, resulting in cooling effect. Will be greatly discounted.
Guige technician experience:
The decrease in cooling capacity under normal conditions of use is usually caused by poor ventilation or excessive ambient temperature.
2, the machine noise becomes bigger
Machine performance:
The machine is normal, but the sound is louder than before!
Answer questions:
This problem is also caused by the lack of daily maintenance. The principle is very simple. Everyone knows that the water tank is used to hold water. There are more or less impurities in the water. The distilled water is not likely to be a little bit of impurities after being added to the water tank. None, in many experiments, the machine does water circulation. The general operating temperature is set at 20 °C. This temperature is especially suitable for the reproduction of microorganisms. After a long time, these microorganisms will block the filter of the waterway and cause the water to return poorly. There is a lot of noise! In addition, microorganisms may also be the chief culprit in the reduction of cooling capacity. After the microorganisms are multiplied, they will attach to the surface of the heat exchanger, resulting in poor heat transfer and reduced cooling capacity!
Guige technicians recommend:
Please do the daily maintenance work of the machine, regularly clean the tank, and keep the tank dry after long-term use!
3, similar to water leakage, in fact, condensation caused by temperature difference
Problem Description: Many customers report that there is water leakage in the cryostat. When the machine is doing water circulation, it will occasionally drip on the ground to solve the problem:
Our products are tested in strict accordance with the factory standards. Under normal circumstances, there will be no water leakage. This problem has also been tested by technicians. During the use of the machine, the temperature of the environment is high, and the temperature inside the tank is low, resulting in waterway. The water pump, water pipe joint, and external water pipe are easy to condense dew, not water leakage! The laboratory needs to be kept clean. This phenomenon can be used to open the laboratory air conditioner to reduce the indoor temperature or use the dehumidifier to avoid condensation when using the low temperature thermostat for water circulation!
Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
