Ethylene glycol refrigeration unit made a strong attack and created LNEYA brand in 12 years
Performance enhanced positioning When performing the cooling and heating reaction, in many cases, the refrigerant cannot cool the object to be cooled by itself. Therefore, we need a coolant (or refrigerant) to cool the refrigeration system in a relatively small range. The suitable brine is undoubtedly ethylene glycol. Compared with water, the freezing point is high and the salt water is corrosive. Ethylene glycol is currently a suitable refrigerant for everyone. Therefore, in response to this...

Effect of evaporator on refrigeration system in special instrument for low temperature experiment
The low temperature experiment special instrument is LNEYA's refrigeration heating equipment for the laboratory. The importance of the evaporator is self-evident. So what effect does the evaporator have on the refrigeration system? According to different models, the choice of evaporators for low-temperature experiment special instruments is also different, such as box-type low temperature experiment special instruments, using water tank coil evaporator; open low temperature experiment special...

Como poupar energia na unidade de controlo do termóstato de aquecimento e refrigeração da câmara de vácuo
In the environment of energy-saving and emission-reduction operation, how to operate the LNEYA vacuum chamber cooling and heating thermostat control unit is very important. Let's take a look at a few tips to reduce the consumption and see how to use it. The very important first step in the selection of the vacuum chamber cooling and heating thermostat control unit is that the cooling capacity is too small, which affects the production, and often loses more than the loss; however, the excessiv...

LNEYA bearing freezer refrigeration principle description
LNEYA industrial freezer can be used in the refrigeration process of the bearing industry. Since the use of bearing freezer is relatively large, the performance is very important, so let's talk about the principle today. The refrigerant in the bearing freezer circulates in the refrigeration system under the action of the mechanical energy generated by the compressor, and is repeatedly operated in a gaseous state or a liquid state. During this process, the refrigerant continuously absorbs the ...

Closed circulation cooling system debugging attention note
Closed circulation cooling system needs to pay attention to some common problems during commissioning. Do a good job in debugging work. LNEYA manufacturers remind users that only when they are ready to work can they be better debugged. The preparation work before the commissioning of the closed circulation cooling system is an important part of the debugging process, which may affect the progress of the whole debugging process. Generally, it is necessary to pay attention to the leakage detect...

O princípio do chiller LNEYA
Industrial chillers are commonly used to cool products and machinery for a variety of different applications, including injection molding, tools and die cutting, food and beverage, chemicals, lasers, machine tools, semiconductors and more. In most process cooling applications, the pumping system circulates cold water or water/glycol solution from the chiller to the process. This cooled fluid removes heat from the process and the warm fluid returns to the cooler. Process water is a means of tr...

Quais são os problemas de depuração mais comuns nos banhos de refrigeração a baixa temperatura?
When the low-temperature cooling bath is in debugging, if the local cooling effect is not good, the system may be blocked by foreign matter or the system design is unreasonable and cannot be adjusted normally. At this time, LNEYA removes foreign matter and thoroughly cleans it to adjust the slope of the pipeline. When debugging, it is found that the vibration and noise of the pump are large when it is running. It may be that the axial and radial deviation of the coupling is large. It may be t...

Consequências do facto de o frigorífico de parafuso não devolver o óleo e método de tratamento
In the cooling operation of the screw refrigerator, if the refrigerant is in contact with the lubricating oil, the lubricating oil in the compressor will enter the condenser with the operation of the refrigeration system and the gaseous or misty refrigerant, and the oil separator is encountered. If the effect is not good or the refrigeration system is not well designed, it will cause problems such as poor oil return. If the screw chiller has a problem of oil return, it will cause the lubricat...

Descrição do congelador industrial de temperatura ultra baixa LNEYA
LNEYA industrial ultra-low temperature freezer is mainly used in industrial cold treatment to precipitate uniform, fine and dispersed carbides on the metal structure matrix. The appearance of such a carbide will bring about a significant increase in the wear resistance and friction properties of the metal, and the hardness will also increase, and will directly increase the life of the wear member. The ideal product to replace liquid nitrogen. It can also be used for cold shrinkage of copper s...
