Imitating natural biological surface morphology, groove shape bionic units in different sizes are processed on the existing drilling pump piston working surface to improve the life-span of drilling pump piston. The wear life-span of bionic piston and standard piston is measured in the same experimental condition. The results show that the rational design of groove shape bionic units can obviously increase the life-span of the piston. The highest life-span of the BW-160 type mud pump piston increase rate can amount to 69.52% in this research. The influence of the groove width on the service life of piston is greater than the groove spacing. If the groove shaped bionic unit size is too small, the life improvement of the piston is not obvious. If the shape of the groove body size is too large, it will reduce the life of the piston. The wear mechanism of the bionic piston was analyzed, it shows that the existence of the groove shaped biomimetic unit can optimize the surface force of the piston, increase oil storage space to improve the lubrication condition of interface of the mud pump piston cylinder liner system, and it is an important reason for improving the service life of the mud pump piston.
