Common problems of Shanghai BILON brand cryostat:
1. Aging phenomenon of machine parts
Machine performance:
Cooling speed is getting slower
Answer questions:
Check whether the exhaust port and radiator of the equipment are working properly!
The water circulation in the cryostat bath is easy to use. It is indispensable to do regular maintenance and maintenance work every day. Many common faults of precision instruments are caused by the failure to do the usual maintenance work. The electric power of the water cycle and the heat taken by the refrigerant from the load need to be discharged from the radiator at the front ventilation hood. If the front ventilation hood is filled with dust and willow cotton, etc., it will hinder the heat dissipation, resulting in the cooling effect Will be greatly discounted.
The experience of Shanghai Bilang technicians:
Usually the cooling capacity drops under normal use conditions because of poor ventilation and heat dissipation or high ambient temperature.
2. The machine noise becomes louder
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. As everyone knows, the water tank is used to hold water. There will be impurities in the water. Distilled water cannot be added to the water tank. No, during many experiments, the machine circulates water, and the general operating temperature is set at 20 ℃. This temperature is particularly suitable for the reproduction of microorganisms. After a long time, these microorganisms will block the filter of the waterway and cause poor return water. The pump will There is a lot of noise! ​​In addition, microorganisms may also be the culprit of the reduced cooling capacity. After a large number of microorganisms multiply, they will attach to the surface of the heat exchanger, resulting in poor heat transfer and reduced cooling capacity!
Shanghai Bilang technicians suggest:
Please do the daily maintenance work of the machine, clean the tank regularly, and keep the tank dry if not used for a long time!
3. Similar to water leakage, it is actually a phenomenon of dew condensation caused by temperature difference
Problem statement: Many customers report that there is water leakage in the cryostat. When the machine is doing water circulation, it dripping from time to time on the ground
Answer questions:
The products of Shanghai Bilang Instrument Manufacturing Co., Ltd. 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 technical personnel. During the use of the machine, the temperature in the environment is mainly high, and the temperature in the tank Low, which leads to dew condensation easily in the water pumps, water pipe joints, and external water pipes. It is not a water leakage phenomenon! The laboratory needs to be kept clean. This phenomenon can be turned on when the low temperature thermostat is used for water circulation. Temperature or using a dehumidifier can avoid condensation!
