| YSZ(Y ttria-stabil ized zirconia) | Y2O3+ZrO2≥99.5% | 5.95~6.05 | ≥87 | 200 | 9.6 | 800~1200 | 8~10 |
Ceramic liners and and ceramic plungers of drilling mud pumps (patent products):
If mud is the blood of drilling, the mud pump is the heart of the drilling equipment, and the liner, plunger, valve bodies, seat, piston are the mud pump's hearts. Thus, the life of liner directly affects the drilling efficiency and the cost and the intensity of labor. The mud zirconia ceramic
Liner Products have beenGranted national patent through
Years of independent research. Its life has reached or exceeded 6--12 times than the bimetallic liners under the same condition. This patented ceramic liner have already been completed field trials, have been sold to the Great Wall Drilling Logging Company(GWDC), Bohai Drilling, and Chuanqing Drilling Engineering Company Limited as well as India, and Russia, Europe, the United States and countries.
A) Ceramic liners and ceramic plungers features:
1) Corrosion-resistant, acid-proof alkali, heat-resistant, it can work in the medium of theDrilling mud or other corrosive Liquid etc.
2) High hardness, wear resistance, It can resist high pressure mud of
Sharp or abrasive resistance of The solid particles grinding or
Scour, such as rock debris, quartz Sands, iron ores, scrap iron.
3) Evenly distributed structure For microstructure and smoothly
Surface will improve the life Of the piston.
4) Working pressure is high, no More than 52 MPa (7500 PSI),
To meet drilling deep well, Ultra-deep demand.
