ABSTRACT:
A gas distribution manifold arrangement and methods for the gas precharge of a plurality of associated hydropneumatic hydraulic accumulators. Each accumulator receives, as by an elastic bladder in the accumulator, a precharge of a pneumatic fluid such as nitrogen. Each accumulator has a corresponding gas inlet valve through which pneumatic fluid is admitted to the accumulator. A hollow gas manifold is provided and a separate conduit connects the corresponding gas inlet valve of each accumulator through a corresponding selector valve on the manifold to the interior of the manifold. With the gas inlet valve of each accumulator open, and all of the selector valves on the gas manifold open, charging gas admitted to the gas manifold flows in parallel paths to apply an equal gas precharge to all accumulators. In one operating mode, after the accumulators have been precharged to the desired pneumatic pressure, all of the selector valves on the gas manifold are closed to pneumatically isolate the plurality of accumulators from each other and from the gas manifold. In another operating mode, after the accumulators have been all pneumatically charged to the desired pressure, all of the selector valves on the gas manifold and the gas inlet valves on all accumulators are left open, whereby the plurality of accumulators constantly pneumatically communicate with each other through the gas manifold to provide a constantly equalized pneumatic pressure in all accumulators. The plurality of associated accumulators may be used to provide hydraulic relief to a gyratory crusher.
