r6 Auxiliary Components for Hydraulic Systs 6.1 Accumulators 6.1.1 Operating principles There are three types of accumulators:spring loaded, weight loaded and charged gas.The common used are charged gas accumlators,which can be divided into piston type(Fig.6-1a) and bag type(Fig.6-1b). Fig.6-2 shows an accumulator,which basically consists of 4 parts:shell body 1,interlayer 3,compressible air 2(weight loaded or spring)on the upper of the interlayer and operating oil 4 located under the interlayer and connected with system.It includes two processes:filled in oil fluid(accumulation)and displacement out oil fluid(release) Homepage List Upwards Downward达 Return ExitChapter 6 Auxiliary Components for Hydraulic Systems 3 6.1 Accumulators 6.1.1 Operating principles There are three types of accumulators: spring loaded, weight loaded and charged gas.
