The material of the spiral vane and the advantages of the carbon steel spiral vane

The material of the spiral vane and the advantages of the carbon steel spiral vane

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

What are the common causes of wear of spiral vane

What are the common causes of wear of spiral vane

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.

Forged shaft process and heat treatment

Forged shaft process and heat treatment

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

Optimized process and performance of forged shafts

Optimized process and performance of forged shafts

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 processing procedures

Forging shaft processing procedures

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

The characteristics and uses of steel grating plate

The characteristics and uses of steel grating plate

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

How to machining tubesheet in special materials

How to machining tubesheet in special materials

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.

Tubesheet specification and design size

Tubesheet specification and design size

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 application

Tubesheet in special materials application

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
