HYDRAULIC RECIPROCATING PUMP

摘要

There is disclosed a hydraulic reciprocating pump which comprises a reciprocating pump, two power cylinders, a reversing valve, a pump electric unit and a fuel tank with hydraulic oil. The chamber is separated to a hydraulic chamber and a working chamber by the piston in the reciprocating pump. The working chamber is connected into the one-way valve. The liquid is poured fully into the non-piston chamber of the power cylinder which is connected with the hydraulic chamber of the pump body via the pipeline. A control mechanism of the reversing valve is disposed on the power cylinder. The oil inlet of the reversing valve is connected with the pump electric unit and fuel tank successively by the pipeline. Two oil outlets are connected to the chamber with pistons of the power cylinder separately by the pipeline. The backflow port is connected with the fuel tank by the pipeline.The hydraulic reciprocating pump has simple structure, is easy to manufacture and is suitable for many kinds of situations.
