Technical standard for overhaul of centrifugal pump coupling

The small pump couplings mainly include rigid couplings, toothed couplings and flexible couplings, which are described as follows:

First, rigid coupling

Rigid couplings are generally used on centrifugal pumps with low power. Firstly, the connecting bolts and

Causes and elimination of common wounds in metal cutting machine tools (6)

The welding repair and sticking of the machine tool guide rails is relatively complicated, especially for the repair of large-area wounds. Before construction, it should be considered more carefully. First, we must consider the accuracy of the repair process used for the guide rails. Whethe

Comparison and analysis of various machine tool guides (5)

Other forms of rail

Another type of guide rail commonly used on machine tools is the dovetail guide rail, which is generally used for positioning of moving parts of machine tools. For example: the tailstock of the turning center, the rail system can move the tailstock over it

4 Define continuous knife

The continuous knife type is defined as "parallel cylinder with Z axis" within the safe range. Since the X0, Y0, and ZO points are parallel to the Z axis, the transition between the tool paths will be connected with a cylinder having a radi

Experimental study on diamond thick film end mill (2)

The PCD composite sheet and the diamond thick film were respectively cut into triangular pieces by laser, and the YG3X cemented carbide insert was ground into a sipe of the same size as the triangular diaphragm by special tooling for use in brazing. There is a high interfacial energy between th
