1 铁路制冰厂生产率计算存在的问题铁路设计制冰厂时,首先要根据制冰厂的年用冰量,确定冰厂的昼夜生产能力,即制冰厂的生产率,并根据生产率的大小计算选择制冰设备的规格和数量.制冰厂生产率通常用下式计算. m=p/(365-n) t/d (1)式中: p——制冰厂年用冰量,t; n——一年内工厂因设备检修,停止生产天数,一般取25h: 制冰厂由于所运货物的品种、季节与运量不同,各月份用冰量是不一样的.运送水果、蔬菜的加冰所8～10月的用冰量最多,运送冻肉的加冰所1、2、11、12月用冰量最多.铁路
1 railway ice plant productivity calculation problems The design of ice-making railway plant, the first ice-based ice-making plant to use the amount of ice, ice plant day and night to determine the production capacity, that is, the productivity of ice-making plant, and calculated according to the size of the productivity Select the specifications and quantity of ice-making equipment Ice-making plant productivity is usually calculated as follows: m = p / (365-n) t / d Where: n - Within a year due to equipment maintenance plant to stop the production of the number of days, generally take 25h: ice plant due to the goods transported by the species, season and volume are different, the amount of ice is not the same for each month to transport fruits and vegetables plus Ice from August to October with the largest amount of ice, frozen ice transport ice 1, 2, 11, December with the largest amount of ice.
