Research on casting technology of large zirconium pump body

1 Pump body materials, structural characteristics and requirements The annual corrosion rate of zirconium is less than 0.05 mm, and it has excellent resistance tocorrosive, and zirconium materials are less likely to absorb hydrogen than other applicable materials.Sensitive and therefore more suitable for chemical reaction conditions of high temperature...

Casting process of pump cover of engineering plunger pump

The engineering plunger pump is the key component of the hydraulic system of construction machinery. During the operation of the plunger pump system, the pump cover repeatedly bears the pressure of alternating load, so the pump cover casting must be compact and zero leakage. The shape of the new...

Effect of Sn Element on Crack Defects of CN7M Sand Casting

Pump and valve products are widely used in petroleum, chemical industry, hydropower station, nuclear power station and other fields. For different working conditions, different material grades need to be selected, such as CF8, CF8M, CF3, CF3M and other 18-8 stainless steel materials, which are widely used due to their...
