囊式蓄能器在液压系统中应用

该文对囊式蓄能器的预充气压力大小及温度变化影响液压系统压力脉动进行了理论分析,并提出合理选择囊式蓄能器的预充压力是保证系统压力稳定的必要条件,在使用时应避免环境温度,尤其是油液温度有较大变化。

The author gives a theoretic analysis that the precharge pressure and temperature variation of bladder type hydropenumatic accumulator will im- pact the pressure pulse of hydraulic system. Also does the author draw a conclusion that properly choosing precharge pressure of bladder type hydropenu- matic accumulator is essential condition to ensure system pressure stable. Also does the temperature variation need to be avoided, especially the oil tem- perature variation.
