Beautiful appearance, smooth inner wall, low resistance, good air tightness, high compressive strength, suitable for larger exhaust projects.2. It is relatively fire-resistant and does not require the installation of additional sprinkler fire extinguishing equipment.3. Made of stainless steel, with stable material and minimal damage.4. Stainless steel welded air ducts are suitable for...

Spiral air duct is a thin-walled pipe made of metal strip material rolled into a spiral seam, circular, non welded, non leaking, non leaking, and commonly used for air supply and bulk material transportation, replacing traditional white iron pipes (i.e. manually seam iron pipes). It is a type of air duct with a full mechanism, and straight pipes do not require manual tapping. Its main uses are...

1. Nano sand mills are usually equipped with high-precision isolation gaps, which not only have self-cleaning functions, but also effectively apply grinding media with particle sizes between 0.4 and 2 millimeters, thereby improving the accuracy and efficiency of grinding.2. The grinding chamber is made of highly wear-resistant materials, which greatly extends the service life of the equipment...

The grinding system is the core part of the nanogrinder, which crushes materials to the nanoscale through high-energy ball milling, vibration ball milling, and other methods. In this process, the selection of grinding media, the material of the ball milling tank, and the control of grinding parameters are all important. For example, high-energy ball milling utilizes a high-speed rotating...

Construction machinery field: In construction machinery, such as excavators, the piston rod plays an important transmission role. For example, in a certain factory, the piston rod of an excavator broke. Through macroscopic and microscopic fracture analysis, chemical composition analysis, metallographic microstructure analysis and other means, failure analysis was carried out. The results show...
