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...

Come proteggere il frigorifero a bassa temperatura zero-86 gradi?
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...

Parti di apparecchiature aerospaziali Istruzioni per la risoluzione dei problemi di refrigerazione del congelatore di prova criogenico
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...

Come scegliere le apparecchiature di prova dell'invecchiamento a bassa e ad alta temperatura?
La capacità di refrigerazione e l'intervallo di temperatura dei materiali nei diversi settori industriali sono diversi. In generale, la capacità di raffreddamento è suddivisa in 80kw, 120kw, 180kw, 240kw, 360kw, e la temperatura di raffreddamento varia da -25°C a -5°C. La velocità di raffreddamento è elevata. È sicuro e affidabile e viene utilizzato per il raffreddamento rapido dei liquidi. È ampiamente utilizzato nelle industrie high-tech come quella petrolchimica, medica, farmaceutica, biochimica, di liofilizzazione, farmaceutica, militare e così via.

Ghiaccio del gruppo refrigerante criogenico antideflagrante, sapete cosa sta succedendo?
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...

Descrizione dei guasti comuni del gruppo frigorifero a semiconduttori LNEYA
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...

Come scegliere un evaporatore di prova per batterie di potenza?
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...

Come rimuovere le incrostazioni del condensatore a fascio tubiero dei frigoriferi a bassissima temperatura？
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...

Accessori per sistemi di controllo della temperatura di refrigerazione dei semiconduttori
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...

Throttle component of semiconductor water-cooled temperature control platform
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...
