Abstract

There is disposed a hydraulic reciprocating pump which comprises a reciprocating pump, two power cylinders, a reversing valve, pump electric unit and 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.

Description

1. Technical field [0001] The invention relates to a pump, in particular to a hydraulic reciprocating pump using liquid to transmit power. 2. Background technology [0002] A pump is a mechanical device that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid, so that the kinetic energy of the liquid is increased and transported along the pipeline. Pumps are mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquids, gas mixtures and liquids containing suspended solids. According to the working principle, pumps can be divided into positive displacement pumps, dynamic pumps and other types of pumps, such as jet pumps, water hammer pumps, electromagnetic pumps, and gas lift pumps. [0003] The positive displacement pump relies on the working element to reciprocate or rotate in the pump cylinder, so that th...
