高速船舶主动力装置采用液压传动的可行性

摘要

After the high-speed ship adopts the hydraulic propelling plant, the position of the main engine in the na-celle will not be limited because the direct connection between the propeller and the principal axis is changed. Without changing the rotational speed of the main engine, the speed and direction of the propeller can be altered with high mobility and flexible operation. The relief valve is used to better deal with the blockage or sudden load increase of the propeller, and guarantee the safety of the diesel engine. The hydraulic motor can provide the rotating speed and torque required for the propeller during the running of the high-speed ship.%高速船舶推进装置采用液压推进装置后,由于改变了螺旋桨与主轴直接连接的方式,主机在机舱的位置将不受限制.在不改变主机转速的情况下,可以实现螺旋桨的调速与变向,机动性高,操纵灵活.通过溢流阀可以很好地解决螺旋桨堵转或者负载突增的问题,保证柴油机的安全.液压马达可以提供给高速船舶行驶时螺旋桨所需的转速和扭矩.
