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.
Tubesheet in special materials is to drill holes slightly larger than the outer diameter of the pipe on the circular steel plate. It is a round steel that plays the role of fixing the pipe and sealing medium in the heat exchanger. It is a kind of fitting
Due to different applications, it is necessary to cut and cut ASTM Corten A weathering steel plate to achieve good results. Due to the durability of ASTM Corten A weathering steel plate is better and stronger, it is inevitable to spend effort, time and mo
Many people think JIS G3114 SMA 50 AW weather resistant steel plate to do rust is very simple, think the liquid spray in JIS G3114 SMA 50 AW weather resistant steel plate surface can, in fact JIS G3114 SMA 50 AW weather resistant steel plate to do rust is
