Semiconductor laser automatic temperature control equipment accessories fault solution
Semiconductor laser automatic temperature control compressor frosting, may be circulating water circulation or valve is not open, check the water valve, all pipelines, to ensure smooth, install short-circuit pipeline. It may be that the circulating water pipe is too small, and the diameter of the circulating water pipe is increased to ensure the normal water circulation. Semiconductor laser automatic temperature control icing in the circulating water tank may be set too low to correct the set...

ゼロから86度の低温冷蔵庫を守るには？
The structure of the scroll compressor and the piston compressor in the low-to-86 degree low-temperature refrigerator is different, and it cannot be reversed. The reverse phase of the three-phase power supply of the low-zero-86 degree low-temperature refrigerator will cause the compressor to reverse, so it is necessary to install reverse phase protection. To prevent the refrigeration press from reversing. After the reverse phase protector is installed, the compressor can be operated in the no...

航空宇宙機器部品極低温試験フリーザー冷凍トラブルシューティング説明書
Cooling water inlet temperature is too low Ultra-low temperature freezer for ultra-low temperature testing of aerospace equipment components As the temperature of the cooling water decreases, the compressor discharge pressure, exhaust temperature, and filter outlet temperature are reduced. The temperature remains the same, because the cooling water temperature has not dropped to the extent that it will affect the cooling effect. If the temperature of the cooling water drops to a certain level...

Explosion-proof cryogenic refrigeration unit icing, do you know what is going on?
When using an explosion-proof cryogenic refrigeration unit, many users do not know how to solve the problem of icing and frosting. In fact, the professional can tell you with certainty, no. The two causes are different, so the processing method is different. If you want to solve the problem of icing in explosion-proof cryogenic refrigeration units, you must first find the problem. Let's share some of the experience in this area. In the actual use of explosion-proof cryogenic refrigeration uni...

LNEYA半導体冷凍ユニット共通故障説明書
If a high-voltage alarm occurs in the semiconductor refrigeration unit, it is necessary to check whether the external piping is blocked or dirty. Clean and remove in time. If it is an air-cooled semiconductor refrigeration device, it is necessary to check the space ventilation condition of the semiconductor refrigeration device. If the space is small and the ventilation is not good, it is easy to cause a high-pressure alarm. In addition, if the compressor discharge pressure is too high, press...

How to choose a power battery test evaporator?
The corrosion of ferrous metals by salt water is very strong, and its corrosion is more severe when it comes into contact with air. Therefore, as far as the production process permits, closed loops should be used as much as possible. For volatile refrigerant circulation systems, a closed cycle must be used. In both cases, the horizontal battery tube evaporator is a suitable choice for the power battery test group. The tank immersed evaporator is used in an open circulation system with a non-v...

半導体冷凍温度制御システムアクセサリー
In the evaporator, since the liquid evaporates in the evaporator of the semiconductor refrigeration temperature control system, the process from liquid to gas, due to the change of the load, some of the refrigerant may not be completely evaporated, but will directly enter the compressor. . Due to the incompressibility of the liquid, it is necessary to pass through the gas-liquid separator before entering the compressor to ensure that all the compressors enter the compressor and ensure that th...

半導体水冷温度制御プラットフォームのスロットルコンポーネント
The throttling component of the semiconductor water-cooled temperature control platform is one of the four major components that are indispensable for the refrigeration system. Its function is to reduce the pressure of the high-pressure liquid coming out of the condenser, so that the liquid refrigerant vaporizes and absorbs heat at low pressure (low temperature). Therefore, it is an important component for maintaining high pressure in the condenser and low pressure in the evaporator. The thro...

Common faults of plate heat exchangers in new energy vehicle inspection
The reason for the excessive pressure drop of the new energy vehicle detection is that the running system pipeline is not properly purged, especially in the newly installed system pipeline, many dirt (such as welding slag) enters the interior of the plate heat exchanger due to plate heat exchange. The cross-sectional area of the flow channel is narrow, and the sediment and suspended matter in the heat exchanger gather in the corner hole and the diversion zone, resulting in a large decrease in...
