YHZ主機(jī)液壓橫向支撐裝置
YHZ M/E HYDRAULIC LATERAL DEVICE概述 Overview
YHZ主機(jī)液壓橫向支撐裝置安裝在主機(jī)和船體結(jié)構(gòu)強(qiáng)梁之間,其功能主要用來降低主機(jī)運(yùn)行中產(chǎn)生的固有頻率,從而降低主機(jī)振動所產(chǎn)生的影響,減少船體的變形量,提高船舶航行的舒適性。其相對于主機(jī)的熱膨脹以及船舶裝載所產(chǎn)生的縱向和橫向位移來說是柔性的。
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.
主機(jī)液壓橫向頂推支撐裝置其標(biāo)準(zhǔn)配置方式是分別安裝在主機(jī)的左舷(凸輪軸側(cè))和右舷(排氣側(cè)),特殊情況下也可安裝在同舷(同側(cè))。主要適用于WinGD、Wartsila等低速主機(jī)。其標(biāo)準(zhǔn)的安裝方式為4缸。其按照結(jié)構(gòu)型式分為整體式和分體式(液壓油缸和液壓蓄能器分開,中間的連接管路由船廠提供,型號中F表示)兩種。
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 ).選型參數(shù)表
