1.1 Introduction concerning duties of compressorsThe following guidelines are given to help interested parties in differentiating between-light duty-medium duty-heavy duty(see also ISO 5388)1.2 Reciprocating oil-lubricated and rotary drip-feed air compressorsWhether the duty of reciprocating and rotary drip feed compressors is to be classified as light, medium, orheavy depends on many parameters, for examplea) the compressor design, ie, type of cooling, number of stages, valve velocities, oil retention time, etcb) ambient conditions, ie, intake "air" temperature, coolant temperature, presence of catalytic dust or gases, etc;c) operating conditions, ie, continuous or intermittent service, layout of the pressure system, maintenance, oil change intervals, etcThe ultimate criterion is satisfactory, reliable air compressor operation with the prevention of excessive oilretention or the formation of coke deposits in the hot discharge air system1.3 Rotaryoil-flooded air compressorsWhether the duty of rotary oil-flooded air compressors is to be classified as light, medium, or heavydepends on many parameters, for examplea) the compressor design, ie, air discharge pressure and pressure ratio, number of stages, oil recirculation rate, oil separating system, etc;b) ambient conditions, ie, intake air temperature and humidity, presence of contaminants (dust or gases), etc;c) operating conditions, ie, continuous or intermittent service, maintenance, oil change intervals, discharge temperature, etcNOTE--Conditions such as air humidity or Iow circulating air volume may recommend an oil for heavier duty
因此要求评定油品生成泡沫的倾向性(ml)和泡沫稳定性(ml)。 这个项目主要用于评定内燃机油和循环用油(如液压油、压缩机油、齿轮油等)的起泡性。润滑油产生泡沫具有以下危害:1. 而稳定的泡沫,会使体积增大,易使油品从油箱中溢出;2.增大润滑油的压缩性,使油压降低。如液压油是靠静压力传递功的,油中一旦产生泡沫,就会使系统中的油压降低,从而破坏系统中传递功的作用。...
锂早先的主要工业用途是以硬脂酸锂的形式用作润滑剂的增稠剂,锂基润滑脂兼有高抗水性,耐高温和良好的低温性能。如果在汽车的一些零件上加一次锂润滑剂,就足以用到汽车报废为止。在冶金工业上,利用锂能强烈地和氧、氮、氯、硫等物质反应的性质,充当脱氧剂和脱硫剂。在铜的冶炼过程中,加入十万分之一到万分之一的锂,能改善铜的内部结构,使之变得更加致密,从而提高铜的导电性。锂在铸造优质铜铸件中能除去有害的杂质和气体。...
