Cooling capacity The refrigeration capacity of industrial low-temperature cold assembly box is directly related to the normal use of production equipment and operation efficiency. If the cooling capacity is too small, the ideal cooling effect can not be achieved. In light of the cooling capacity, the production efficiency will be reduced, and the energy consumption… Read more Selection of industrial low temperature cold assembly box

Cryogenic box automobile assembly machinery gear cold assembly industrial refrigerator
The interference fit problem of hole and shaft parts is often encountered in the process of mechanical equipment maintenance and assembly. However, due to the lack of conditions for the implementation of modern assembly technology, the interference assembly of hole and shaft parts by thermal expansion method is a commonly used technical means in actual… Read more Cryogenic box automobile assembly machinery gear cold assembly industrial refrigerator
Main advantages of cold assembly technology for industrial refrigerator
Cold assembly technology of industrial refrigerator is not only suitable for manual operation, but also can be used in assembly line First, energy saving. This can be understood from two aspects. On the one hand, industrial refrigerators do not need any rare resources, only need to use electric energy. Therefore, the promotion of cold assembly… Read more Main advantages of cold assembly technology for industrial refrigerator
Cold assembly technology of industrial refrigerator
Generally, when the temperature changes, the volume of the object will always change. Most objects (including solid, liquid, gas) will increase when the temperature rises, and the volume will decrease when the temperature decreases. This phenomenon is called thermal expansion and cold contraction. In industrial production, the phenomenon of thermal expansion and cold contraction is… Read more Cold assembly technology of industrial refrigerator
The cold assembly process
Cold assembly is a kind of assembly method that uses cooling medium to cool the parts which need to be installed in the base hole first, so as to shrink their dimensions and generate assembly clearance between the assembly surfaces, so as to facilitate the assembly of parts. Characteristics of cold charging process (1)It is… Read more The cold assembly process
Precautions for cold assembly of stern tube bearing industrial refrigerator
Precautions for cold assembly of stern tube bearing industrial refrigerator (1) Before installation, all parts shall be cleaned and cleaned without oil, water, sand and other sundries. (2) When assembling the flange bolts between shafts, the flange shall be positioned with temporary bolts. The neck of the positioning bolt shall be 0.01-0.02MM loose according to… Read more Precautions for cold assembly of stern tube bearing industrial refrigerator
Cold assembled stern tube bearing
Stern tube bearing is a very important technology in ship power system. Its installation technology is directly related to the safety performance of ship operation. The use of dry and cold assembly technology can control the clearance of bearings, reduce the wear of related parts, and extend the service life of main parts. At the… Read more Cold assembled stern tube bearing
Shaft and rotor cold assembled industrial refrigerator
In the refrigeration compressor, the assembly of the shaft and the rotor is usually realized by the interference heat installation. Shrink fit mainly uses the expansion and contraction properties of materials. Put the heated expansion rotor on the shaft. When the rotor is restored, the hoop force on the shaft will be generated to ensure… Read more Shaft and rotor cold assembled industrial refrigerator
Large mechanical parts cold assembly of industrial refrigerator
In the assembly process of mechanical parts, the interference fit between the hole and the shaft usually adopts pressing method or temperature difference method. For small parts with low assembly requirements and small interference, pressing method is often used, that is, hammering or machine pressing method. The defect of this method is that it can’t… Read more Large mechanical parts cold assembly of industrial refrigerator
Cold assembly method of bushing parts
The cold assembly of bushing parts used in construction machinery is based on the principle of heat expansion and cold contraction of materials, that is, the bushing is frozen first It is the dimension shrinkage of the bushing (changing the interference fit into clearance fit), and then in the process of assembly, the cold assembly… Read more Cold assembly method of bushing parts
