船用空气压缩机有以下几种:即1)启动柴油机用的压力为25、30或35公斤/厘米~2的中压主空气压缩机;2)在无压缩空气情况下,为启动柴油发电机而由小型油机带动的小排量应急空气压缩机,它本身的启动是靠手动空压机供给少量的压缩空气而启动的;3)作为杂用兼自动控制用压力为9公斤/厘米~2的低压空气压缩机等。 1.空气量螺旋桨直联的柴油机主机要求充气到船级社规定的压力,在中途不充气情况下,气瓶容量要能够供给12次以上启动用,同时要求主空气压缩机在一小时内能充满气瓶。各仲不同型式的主机在马力相同下启动所需的空气压力和容量是不同的,实际上按规定的容量加些余量,大约可以供20次左右启动用。
Marine air compressors are the following: 1) Starting medium-pressure main air compressors with a pressure of 25, 30 or 35 kg / cm 2 for diesel engines; 2) In the absence of compressed air, The small displacement oil displacement compressor driven by a small air compressor, its own start by manual air compressor to supply a small amount of compressed air and start; 3) as a hybrid and automatic control with a pressure of 9 kg / cm ~ 2 low-pressure air compressor and so on. 1. The air volume direct propeller direct-coupled diesel engine requires inflation to the classification society pressure, in the case of non-inflation, the cylinder capacity to be able to supply more than 12 starts with the main air compressor requires an hour Full of gas bottles. Each of the two different types of host horsepower at the same start under the required air pressure and capacity are different, in fact, according to the provisions of capacity plus some margin, about 20 can be used for starting.
