The Analysis for the Leaking Flowrate in the Plane Valveplate
Abstract:
A new computation for the leaking flowrate in the plane valveplate sector of the pistons pump considering the influence of the flow inertia is proposed. Establish the theoretical math model about the flow field, based in the N-S equation and the sequence equation, and the leaking flowrate in the plane valveplate sector considering the influence of the flow inertia is computed in the boundary conditions of the press and the velocity. It is not the same as the common formula that the leaking flowrate computation formula established in this paper includes the factor of the flow inertia in the plane valveplate sector, which can reflect the influence of the flow inertia. The theory computation is checked by the FEM simulation. The theory computation result is approximate with the simulation result. The computing results indicate that the leaking flowrate of the plane valveplate sector increases when the press and the height of the seam increase, just as the other conditions are the same. And the flow inertia leads to the increase of the leaking flowrate, the influence is obvious in some conditions.
