As is well known, zirconia cylinders have an external steel shell and an inner layer of zirconium dioxide (ZrO2), which has high hardness, low reactivity, and a high melting point.
Zirconia liners were invented more than 20 years ago, and since then their mass use in bentonite mud pumps has begun.
Features:
- Not subject to corrosion;
- Smoother surface, which significantly reduces friction and heating;
- High density and wear resistance of the inner surface of the liner;
- Hardness of the working zone 92–94 HRC;
- Due to their high technical characteristics, service life is 2000–3000 hours;
- Extended maintenance intervals due to the reliability and quality of the products;
- Increases piston life up to 2 times, thanks to reduced surface resistance;
- Ceramic cylinders reduce drilling costs and labor intensity.
Taking into account all the advantages, an important point should be considered!
Under optimal operating conditions, zirconia liners last 10 times longer than steel ones, and the cost per hour of operation is up to 70% lower.
Wear of the liner is possible if it remains in the same position.
For this reason: to achieve maximum durability of zirconia liners, it is extremely important to rotate the insert by 1/4 turn every 600 hours of operation. In addition, the gasket of the insert should also be replaced during scheduled maintenance.
Expected service life depends on proper alignment/maintenance of the pump and drilling conditions.
