The principle of LNEYA chiller
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...

What are the common debugging problems in low temperature refrigeration baths?
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...

The consequences of the screw refrigerator not returning oil and the treatment method
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...

Description of LNEYA industrial ultra-low temperature freezer
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...

How to choose a heating and cooling circulating water bath?
Heating and recirculating water bath In the process of selection, heating power, cooling power, pressure and flow are also factors that users need to consider. Good system design and accessory brand selection are related to the whole heating and cooling cycle water bath selection. As far as the heat transfer medium of the heating and cooling cycle water bath is concerned, water is used as a heat transfer medium, which is economical and environmentally friendly. Even if a leak occurs, it can b...

Basic maintenance of high and low temperature refrigeration circulating pumps
Properly perform the sequence of opening and closing of the high and low temperature refrigeration cycle pump group to ensure normal operation after the host is started. Note that the condenser heats up well, otherwise the high temperature protection device of the high and low temperature refrigeration cycle pump group will stop and even cause malfunction due to the condensing temperature and the corresponding condensing pressure being too high. The cold water in the evaporator should be circ...
