| 中文摘要:为解决往复泵恒压力恒流量输出问题，设计了一种液压双缸单作用泵。其液压系统由双油泵供油，采用带单向机构的转阀与普通换向阀相结合的油量分配方式，转阀动作由活塞行程控制，转阀动作精度不受主油泵变量的影响，系统控制可靠。该泵在实际应用中取得了良好的效果。 |

| Abstract:In order to resolve the constant pressure and flow output problems of reciprocating pump, a kind of hydraulic pump with double-cylinder and single acting was designed. Hydraulic system of the pump is made up of 2 hydraulic pumps. The oil is supplied to the hydraulic system using double oil pump with oil mass distribution mode combining a unidirectional mechanism turning valve and an ordinary turning valve. The action of turning valve is controlled by the piston strokes and the action precision of valve is not under the influence of the changing of main hydraulic pump displacement. The system is controlled reliably with good result in practical application. |
