The tower equipment is a process equipment with a cylindrical welded structure, which is composed of a cylinder, a head (or cover) and a support. It is a non-standard equipment specially designed and manufactured for a certain production process requireme
Stainless steel spiral vane have strong durability, wear resistance and aesthetics. It can effectively prevent moisture and water penetration, and is not easy to rust, corrosion and oxidation resistance.
Screw conveyors are widely used and are often used for conveying materials, such as massive, granular, powdery and other materials, or some high-temperature and corrosive materials, instead of manual handling and higher efficiency. Common spiral blades in
In the running-in phase of the spiral vane, because the product is relatively rough, large friction will be generated at this time. The frictional force at this stage is great for the wear of the spiral vane. Users need to pay attention to this point.
Different forging methods have different processes. Among them, hot die forging has the longest process. The general sequence is: blank blanking; blank heating; roll forging blank preparation; die forging forming; trimming; punching; straightening; Interm
The forming of the forged shaft is produced under the action of external force. Therefore, the correct calculation of the deformation force is the basis for selecting equipment and checking the mold. Analysis of stress and strain inside the deformed body
Forging shaft is metal in solid state after heating through forging and pressing forming, it requires metal to have good thermoplastic, general forging shaft are steel parts, its high strength, plastic calculation and blanking is one of the important link
Steel grating plate is made of flat steel in accordance with a certain distance and twisted square steel cross arrangement, with pressure welding machine or artificial welding. The surface after hot dip galvanized or plastic spray treatment, so as to achi
The tubesheet used for class III and IV pressure vessels needs relatively high precision. The traditional hole processing methods are bench marking and rocker drilling.
In the calculation of fixed tubesheet, the axial stress of shell, the axial stress of heat exchange tube and the pull-out force Q between heat exchange tube and tubesheet are calculated according to various working conditions with temperature difference.
