The piston is one of the parts that most easily become worn out and experience failure in mud pumps for well drilling. By imitating body surface morphology dung beetle, this paper proposed a new type (BW-160) pump had dimpled shape regular layout on leather cup carried performance test self-built rig. Firstly, influence different dimple diameters service life was analyzed. Secondly, analysis central included angle under same area density obtained. Thirdly, wear time experimental results...
Bionic strips were designed and processed on the piston of BW-160 slime pump to improve its friction performance, decrease wear mass losses, prolong service life. Nine stripped pistons manifested by different strip depths included angles between stripes surface. A workbench was created test frictional force, oil film width, losses. Test results demonstrated that structure can significantly force piston. Optimal depth, angle, resistance reduction rates for reached 2 mm, 90°, 53.89%,...
In the demanding environment of drilling mud pumps, failures attributed to piston wear constitute approximately 80% malfunctioning incidents.While enhanced structural designs and superior materials have been employed, enduring challenges remain.A potential solution identified in previous works is surface texturing, specifically optimization pit structures on rings, with promising outcomes friction reduction.Yet, vital role thermal parameters high-intensity environments like pumps has largely...
