Wear Performance of Bionic Dimpled-Shape Pistons of Mud Pump
Table 3
Wear patterns of pistons with different dimple diameters.
| | Piston number | Diameter of dimple at lip, D (mm) | Spacing, L (mm) | Central included angle, α (°) | Diameter of dimple at root, D′ (mm) | Average wear mass percentage of piston |
| | L-Standard | 0 | 0 | 0 | 0 | 6.98 | | T1 | 1.5 | 5.5 | 12 | 1.5 | 6.59 | | T2 | 3 | 5.5 | 12 | 3 | 4.22 | | T3 | 4.5 | 5.5 | 12 | 4.5 | 3.83 |
