Industrial grade heating and cooling system placement attention
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 ...

How to protect the zero-86 degree low temperature refrigerator?
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...

Aerospace equipment parts cryogenic test freezer refrigeration troubleshooting instructions
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...

¿Cómo elegir los equipos de ensayo de envejecimiento a baja y alta temperatura?
The refrigeration capacity and temperature range of materials in different industries are different. Generally speaking, the cooling capacity is divided into 80kw, 120kw, 180kw, 240kw, 360kw, and the cooling temperature ranges from -25°C to -5°C. The cooling rate is fast. It is safe and reliable, and is used for rapid liquid cooling. It is widely used in high-tech industries such as petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical, military and so on. Materia...

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 semiconductor refrigeration unit common fault description
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...

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...

Cómo eliminar las incrustaciones del condensador de carcasa y tubos del frigorífico de temperatura ultrabaja？
Low-temperature refrigerator ultra-low temperature condenser scale removal In general, we have three methods, namely mechanical descaling, chemical pickling and descaling, and electronic magnetic water separator descaling. Low-temperature refrigerator ultra-low temperature mechanical descaling is the use of soft shaft washing tube The method for descaling the condenser of the cooling pipe is particularly suitable for a vertical shell and tube condenser. The specific operation is to first with...

Semiconductor refrigeration temperature control system accessories
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...
