Material of ceramic shaft water pump:
Usuaully the ceramic shaft water pump materials are alumina ceramic and zirconia ceramic.
Alumina Ceramic shaft water pump：
1.They have high mechanical strength. The flexural strength of sintered alumina ceramic products can reach 250MPa, and that of hot-pressed products can reach 500MPa. The strength can be maintained up to 900℃ at high temperatures.
2. High alumina ceramics have a high resistivity and excellent electrical insulation performance. The resistivity at room temperature is 1015Ω·cm, and the insulation strength is 15kV/mm.
3.High hardness, with a Mohs hardness of 9.
Machining of ceramic shaft water pump:
Straightness machining of precision ceramic rod
The straightness of the ceramic rod is related to the length of the ceramic rod, the longer the easier it is to bend, generally the 100mm long ceramic rod we can control the straightness of 0.1mm, and the straightness of 300mm is 0.5mm.
Cylindrical machining of precision ceramic rod
The outer circle of the ceramic rod generally needs to be cylindrical grinding, and the roundness of the ceramic rod can reach 0.003mm.
