拖轮主推进柴油机油耗计量装置
本技术涉及一种拖轮主推进柴油机油耗计量装置,属于船舶设备
技术介绍
拖轮主推进柴油机燃油供给系统由燃油舱、日用油柜、流量计、进回油管路、相关阀件等组成,由于进入拖轮主推进柴油机的燃油不会全部用来燃烧,会有部分回油通过回油管路返回燃油舱或日用油柜。所以目前拖轮主推进柴油机油耗量的计量一般采用间接计量法,即在进油管路和回油管路各安装一只流量计,分别计量进油量和回油量,用进油量减回油量计算得出燃油消耗量。而拖轮一般有两台主推进柴油机,采用常规计量方式则需要分别在进/回油管共安装四台流量计,成本较大,且计量稳定性和精确性差。
技术实现思路
本技术所要解决的技术问题是提供一种拖轮主推进柴油机油耗计量装置。为实现上述目的,本技术提供了一种拖轮主推进柴油机油耗计量装置,燃油从燃油舱流出,经过日用油柜、流量计1在拖轮主推进柴油机内置油泵的作用下经依次设置单向止回阀7、三通接头一8、三通接头二9的进油管路一后分为进油支路一和进油支路二,主推进柴油机一分别连接进油支路一和回油支路一,主推进柴油机二分别连接进油支路二和回油支路二,回油支路一和回油支路二分别通过设置三通接头三10的管路连接燃油回收柜5,燃油回收柜5上安装透气管,燃油回收柜5通过回油管路连接进油管路。所述流量计选用质量流量计。所述燃油回收柜的位置低于日用油柜位置。所述燃油回收柜中的透气管的顶端高于日用油柜。所述燃油回收柜的容积日用油柜容积的十分之一。本技术的有益效果是:通过增加一个燃油回收柜及对部分回油管路路线改造,在不影响主推进柴油机正常工作和实现油耗量正确计量的情况下,减少了流量 ...
