The Analysis of Piston-Barrel Leakage in a Superhigh Pressure Water Hydraulic Piston Pump
Leakage is an important parameter to evaluate the performance of seal in a water hydraulic pump,especially in a superhigh pressure one.A leakage model of piston-barrel seal structure in the superhigh pressure water hydraulic piston pump rated 80MPa pressure and 8L/min flow was set up in this paper.The influences of clearance size,contact length and pressure drop of clearance on the leakage were numerically studied.The results show that this type of seal structure performs well in the superhigh pressure water hydraulic piston pump,which will guide the optimal design of the pump and point out the direction of next-step experiments.
