Due to the absence of common understanding among the naval architects,engine-builders and marine engineers,about the definition of marine diesel engine power rating,difficulties aroused by power deficiency in diesel-installations on board were frequently eneountered in service.This paper deals with diesel engine power rating from manufacturing and service point of view.The manufacturers should rate their engines into three ranks:maximum rating,nominal rating and over-nominal rating. The marine engineers should rate their auxiliary engines into two ranks,namely,normal service rating and overload rating,and their main propulsion engines into trial trip rating,maximum service rating and normal service rating.Scientific definifion of these ratings are explained and their empirical relati- ons are also given. The bases of nominal rating are standard ambiant atmospheric conditions and installation condi- tions.The author proposes that standard ambiant atmospheric conditions should be based on the mean conditions in the test shop of the most diesel engine factories throughout the country.However,the naval architects should rate their engines according to the particular conditions of the appointed navigation zone and the kind of service to be attained.Numerical data of ambiant atmospheric conditions and installation conditions proposed are:736mmHg.,20℃,70% humidity,and less than 150 mm WG vacuum in the intake air system,30～300mmHg back pressure in the exbaust system.The calculation method in practice for correcting nominal rating and specific fuel consumption according to the variations of ambiant atmospheric conditions differ largely one another.For non-supercharged diesel engines,new correction formulas according to constant fuel pump rack and constant fuel/air ratio respectively are recommended in the paper.The results of comparison of these proposed fornmlas with others in practice and also with published test data show that the recommended formulas are more reasonable,although the correction is still slighly too high. The ambiant conditions on board differ largely with those in test shop,so the determination of service rating depends upon the specification of ambiant atmospheric conditions in the machinery compartment.Three kinds of standard ambiant conditions in machinery compartment,for high sea,east- south sea and north sea-going ships respectively,are given in this paper.These numerical data are deter- mined by statistical method.In the determination of service rating,the influence of wear,rpm.,insta- bility and power reserve must be considered.Its empirical coefficients are introduced.Generally,the normal service rating for auxiliary engines is about 75～82% of the nominal rating from manufacturer and 70～99% for the main propulsion engines.
船用柴油机功率的定义在设计、制造和使用各方面缺少统一的理解,以致使用时常常出现柴油机功率满足不了需要的问题。本文提出船用柴油机功率分级应从制造及使用两方面分别加以考虑:从制造方面可分为最大功率、额定功率和超额功率三级;从船上使用方面,驱动发电机的付柴油机可分为持久功率及超额功率两级,而推进用的柴油机则应分为试航功率、最大使用功率和正常使用功率三级。本文给出了上述各种功率的科学定义和经验比例。额定功率的标定基础是标准大气条件和安裝条件,标准大气条件的选择原则应根据国内大部份柴油机车间的条件而定,而使用者別应根据具体航区和船的用途重新标定持久使用功率。本文建议的标准大气条件为736毫米汞柱,20℃和70%湿度,并提出进气系统真空度不超过150毫米水柱、排气背压应为30～100毫米汞柱。目前使用的各种额定功率及耗油率修正计算方法差别较大,本文对非增压柴油机分别按每循环供油量不变及燃烧空气过量系数不变两种情况提出了新的修正计算公式。运用本文介绍的公式计算结果与试验结果,比较表明本文建议的公式比较合理,但仍略偏于保守。船上机仓内的大气条件与工厂条件相差较大,投使用功率的选定应以机仓大气条件为准。作者根据统计提出适合在远...
船用柴油机功率的定义在设计、制造和使用各方面缺少统一的理解,以致使用时常常出现柴油机功率满足不了需要的问题。本文提出船用柴油机功率分级应从制造及使用两方面分别加以考虑:从制造方面可分为最大功率、额定功率和超额功率三级;从船上使用方面,驱动发电机的付柴油机可分为持久功率及超额功率两级,而推进用的柴油机则应分为试航功率、最大使用功率和正常使用功率三级。本文给出了上述各种功率的科学定义和经验比例。额定功率的标定基础是标准大气条件和安裝条件,标准大气条件的选择原则应根据国内大部份柴油机车间的条件而定,而使用者別应根据具体航区和船的用途重新标定持久使用功率。本文建议的标准大气条件为736毫米汞柱,20℃和70%湿度,并提出进气系统真空度不超过150毫米水柱、排气背压应为30～100毫米汞柱。目前使用的各种额定功率及耗油率修正计算方法差别较大,本文对非增压柴油机分别按每循环供油量不变及燃烧空气过量系数不变两种情况提出了新的修正计算公式。运用本文介绍的公式计算结果与试验结果,比较表明本文建议的公式比较合理,但仍略偏于保守。船上机仓内的大气条件与工厂条件相差较大,投使用功率的选定应以机仓大气条件为准。作者根据统计提出适合在远洋、东南海及比海航行的三种船舶之标准机仓大气条件;同时推荐了在送定使用功率计算中为考虑磨损、转速不稳性及功率贮备等因素所采用的系数。对于发电用的柴油机船上使用功率一般为额定功率的76～82%,对于推进主机则为70～79%。近年来,在我国船舶上,通常发现由于各方面对船用柴油机功率标定缺少统一妁理解,往往引起柴油机的实际使用功率超出其能力,以致引起柴油机超负荷、螺旋桨转速或发电量达不到设计要求,严重的甚至会引起发动机损坏。柴油机功率按不同大气条件的修正亦常常引起制造厂与验收部门的争执。这些问题虽然在我国有关标准中已作了某些规定,但仍有继续探讨的必要。本文着重对额定功率与使用功率的关系、标准大气条件的确定以及功率和耗油率按大气条件变化的修正等问题提出一些看法。
