论背压在船舶液压舵机系统中的作用

本文针对背压的特征,对背压在船舶液压舵机系统中的作用进行综述。同步液压回路中保持同步、控制液动阀实现液压管路的转换、消除液压啸叫声、使机构动作平稳、补油等多种作用,对背压阀形式及压力的合理选取,从而提高系统运动时的平稳性,减少对系统的冲击,在某种程度上对一些液压元件及附件起到保护作用,使得船舶液压舵机系统的工作性能更加完善可靠,延长液压系统的使用寿命。

Discussion on the role of back pressure in hydraulic system

This article is aimed at the characteristics of back pressure,The role of back pressure in the marine hydraulic steering system is reviewed,the role of synchronizing in the synchronous hydraulic circuit,the control of the hydraulic valve to realize the conversion of the hydraulic circuit,and the elimination of the hydraulic whistling sound.The action of the mechanism is smooth and the effect of replenishing oil;then,the back pressure is designed in the hydraulic system,mainly the selection of the back pressure valve form and pressure;finally,the reasonable use of the back pressure to improve the system movement The smoothness of the time,the impact on the system is reduced,and some hydraulic components and accessories are protected to some extent,so that the working performance of the marine hydraulic steering system is more perfect and reliable,and the service life of the hydraulic system is prolonged.
