YHZ主机液压横向支撑装置
YHZ M/E HYDRAULIC LATERAL DEVICE概述 Overview
YHZ主机液压横向支撑装置安装在主机和船体结构强梁之间，其功能主要用来降低主机运行中产生的固有频率，从而降低主机振动所产生的影响，减少船体的变形量，提高船舶航行的舒适性。其相对于主机的热膨胀以及船舶装载所产生的纵向和横向位移来说是柔性的。
YHZ M/E hydraulic lateral device is installed between the engine and the hull, to reduce the natural frequencies of the engine and the impact of the engine vibration, the deformation of the hull and improve the comfort of the ship sailing. The hydraulic top bracing units are flexible to thermal expansion of the engine and various longitudinal and lateral displacement of loading conditions of the vessel.
主机液压横向顶推支撑装置其标准配置方式是分别安装在主机的左舷（凸轮轴侧）和右舷（排气侧），特殊情况下也可安装在同舷（同侧）。主要适用于WinGD、Wartsila等低速主机。其标准的安装方式为4缸。其按照结构型式分为整体式和分体式（液压油缸和液压蓄能器分开，中间的连接管路由船厂提供，型号中F表示）两种。
The hydraulic lateral device is installed on the port side (camshaft side) and the starboard side (exhaust side) of the host machine respectively, and can also be installed on the same side (same side) under special circumstances，mainly for WinGD, Wartsila and other low-speed engine. The standard installation for the 4 cylinder. According to the structure type, it is divided into integral type and split type (the hydraulic cylinder and the hydraulic accumulator are separated, the middle connecting pipe is provided by the shipyard, and F indicates the model ).选型参数表
