Abstract
A method of attenuating pressure pulsations, comprises: pumping liquid into a vessel in fluid communication with a flow line by a conduit sealingly passing through a top surface of the vessel, so as to discharge the liquid into the flow line while creating an air-liquid interface in the vessel, by trapping in an upper part of the vessel air that attenuates pressure pulsations caused by the pumping. The method also comprises generating condition for the liquid to drain out of the vessel to allow air to fill at least the upper portion of the vessel.
Claims15
A method of attenuating pressure pulsations, comprising:
- pumping liquid by a pump through an outlet of said pump into a liquid inlet, formed in a vessel of system for attenuating pressure pulsations and being connected to said outlet, wherein said system comprising:
- a conduit in fluid communication with a lower part of said vessel, said conduit sealingly passing through a top surface of said vessel to feed a flow line outside said vessel with said liquid, wherein said liquid inlet is constituted to receive said liquid from said pump in a manner that said liquid enters both said vessel and said conduit, and creates an air-liquid interface in said vessel, by trapping in an upper part of said vessel air that attenuates pressure pulsations generated by said pump;
- at least one drain opening constituted to drain said liquid out of said vessel and to allow air to fill at least said upper portion of said vessel;
- and
- a passive valve at said at least one drain opening, constituted to assume an opened state when said pump is not in operation, and a closed state when said pump is in operation;
- and
- temporarily ceasing said pumping to ensure opening of said passive valve, to drain out of said vessel through said at least one drain opening, and to allow air to fill at least said upper part of said vessel.
A pump system, comprising:
- a pump;
- and
- a system for attenuating pressure pulsations, comprising:
- a vessel having a top surface, an upper part and a lower part;
- a conduit in fluid communication with said lower part, said conduit sealingly passing through said top surface to feed a flow line outside said vessel with liquid;
- a liquid inlet formed in said vessel and being connected to an outlet of said pump, for receiving said liquid from said pump in a manner that said liquid enters both said vessel and said conduit, and creates an air-liquid interface in said vessel, by trapping in said upper part air that attenuates pressure pulsations generated by said pump;
- at least one drain opening constituted to drain said liquid out of said vessel and to allow air to fill at least said upper part of said vessel;
- and
- a passive valve at said at least one drain opening, constituted to assume an opened state when said pump is not in operation, and a closed state when said pump is in operation.
