皮囊式蓄能器由于其反应快、流量大(40L/s)、压力范围广(50MPa)、泄漏损失小、可以长期存储等一系列优点,在储存节约能量、减少压力冲击和脉动等方面,都得到了广泛的应用。皮囊式储能器在储存节约能量方面、既可以均衡机械设备一个工作周期内的动力负载,也可以回收机械设备的动能和位能;在这两种情况下,都能减少设备的动力容量。另外还可以作为应急能源,保证系统的安全可靠;在一些需要保持压力的设备中,蓄能器可以补偿泄漏;使油泵卸荷,从而获得节能效果。在上述几方面的应用中,蓄能器都是作为蓄能元件工作的,但是对蓄能和释能过程的分析,及有关参数选择和容量计算,仍缺 Because of its fast response, large flow rate (40L / s), wide pressure range (50MPa), small leakage loss and long-term storage, the bladder accumulator has many advantages such as saving energy, reducing pressure shock and pulsation, Have been widely used. In terms of saving energy, the bladder-type energy storage device can not only balance the dynamic load of the mechanical equipment during one work cycle, but also recover the kinetic energy and potential energy of the mechanical equipment; in both cases, the power capacity of the equipment can be reduced. In addition, it can also be used as an emergency energy source to ensure the safety and reliability of the system. In some devices that need to maintain pressure, the accumulator can compensate for the leakage and the oil pump can be unloaded to obtain the energy-saving effect. In the application of the above aspects, the accumulators work as energy storage components, but the analysis of energy storage and energy release process, as well as the related parameters selection and capacity calculation are still missing
