Working principle of bypass valve of well plugging device accumulator

Flow from the accumulator can always go to the cylinders through the bypass check valve. Normally in a pump-supplementing circuit, the relief valve is set as high as possible above the working pressure to store ample fluid.

The FDF bypass valve operates on a pressure-differential activation principle, providing an alternative flow path when normal circulation through the bit becomes blocked. Define an accumulator and explain its function A hydraulic accumulator is a device that stores the potential energy of an incompressible fluid held under pressure by an external source against some dynamic force.
