工業用グレードの冷暖房システム配置の注意
Industrial-grade heating and cooling system Before the power is turned on, check whether the voltage specified on the nameplate is the same as the household voltage. The same can be used to arrange separate power lines and special sockets for the industrial heating and cooling system. It cannot be used with other electrical appliances. The same socket, otherwise it will cause a bad accident, the grounding device should be installed, and then the industrial-grade heating and cooling system is ...

グリコール・チラーの設置要件
In the summer, the use of glycol chillers is relatively frequent. Efficient glycol chillers are also needed. Therefore, when installing glycol chillers, they need to be installed on a smooth and tidy floor. Why choose a smooth ground when installing? Users who have known the glycol chiller should know that if the glycol chiller is tilted during installation, it may cause the refrigerant or cooling water or chilled water to operate abnormally, and the refrigerant may flow backward or the resis...

The reason why the semiconductor small thermostat is blocked by refrigeration
The small semiconductor small-scale thermostat ice jam is mainly caused by the excessive moisture contained in the refrigeration system. With the continuous circulation of the refrigerant, the moisture in the refrigeration system gradually collects at the capillary outlet, in view of the relatively low temperature at the capillary outlet, the water It forms ice and gradually increases. When it reaches the necessary level, the capillary is completely blocked, the refrigerant does not recur, an...

Common fuel cell environmental test device inspection method
During the cooling process of the fuel cell environmental test device, there is a chance of dripping inside. This is not a normal phenomenon used by the fuel cell environmental test device, but is caused by improper installation. After the fuel cell environmental test device is installed, test the machine (refrigeration) immediately. If there is no water leakage after running for a certain period of time, there will be no leakage problem. Of course, the installer can also be required to carry...

Minimum 40 degree refrigerator use precautions
The temperature of the lower 40 degree refrigerator is indoor temperature: 5-32 °C, relative humidity 80%/22 °C, the distance from the ground > 10cm, the altitude below 2000m, the safe environment guarantees a smoother operation of the lower 40 degree refrigerator. During the use of the minus 40 degree refrigerator, the samples with strong acidity and corrosiveness should not be frozen. Check the sealing strip of the outer door frequently. The four feet of the floor are stable and level. P...

蒸しシステム温度制御の安全要件
The steaming system temperature control is one of the low temperature refrigerators designed and produced by Wuxi Guanya LNEYA. The temperature range is from -5 °C to -150 °C. The secondary subcooling technology is adopted, the refrigeration is rapid, the refrigeration temperature is low, and the liquid is rapidly cooled. It is widely used in high-tech industries such as petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical, military and so on. Before using the st...

新エネルギー電池試験冷却装置コンプレッサー故障判定
How to identify the three terminals on the fully enclosed compressor casing of the new energy battery test cooling unit? The resistance between the running end (R), the starting end (S), the common end (C), and the RS is greater than the resistance between the SC and the resistance between the RC. The resistance between RS is equal to the resistance between SC and the resistance between RC. It can be discriminated by the above rule, and it should be noted that the resistance values of the ter...

Multi-stage refrigeration system centrifugal compressor repair instructions
After the centrifugal compressor of the cascade refrigeration system is disassembled, the dimensions of each journal (cooperating with the impeller, bearing, coupling, etc.) are measured with an outer diameter micrometer to calculate the roundness and cylindricity deviation. The value should be Within the allowable range. When the tolerance is large, check if the straightness deviation of the spindle is too large. Place the spindle in the casing or place it on the top of the lathe so that the...

バッテリーテスト・ウォータークーラー常識解説
Battery test Water-cooled air intake If there is no superheat, there may be a return air with liquid, and even cause a wet stroke liquid shock to damage the compressor. In order to avoid this phenomenon, a certain degree of suction superheat is required to ensure that only dry steam enters the compressor (the presence of superheat indicates the complete evaporation of the liquid refrigerant due to the nature of the refrigerant). However, the battery test water cooler has too high superheat an...
