140mm api 7k ceramic cylinder liner
THE FEATURES :
1. Compared with Bi-metal liner and Ceramic liner,the service life of cermet liner is 10 times higher.Its maximum
and minimum service life can reach more than 5000hours.
2.The reliability is much higher than the Bi-metal and Ceramic liner.
3.The hardness is up to HRC67~HRC70;
4.Compared with the Bi-metal liner and Ceramic liner(is 0.4), the inner face's glabrous of cermet liner is less than 0.1.
5.Bond strength is greater than 110Mpa of metallurgical combine.
6.Friction coefficient of 0.090.(Far below the double metal and ceramic,) the better the life
of rubber parts for piston an matching.
7.Does not change the assembly processes of the existing mud pump and double metal cylinder.
8.Cermet compressive strength of is over 2000Mpa.
9.Bending strength is over 1000Mpa
10.Acid: PH1.0~14.0
