升降机蓄能器主要有弹簧式和充气式两大类，而充气式又包括气瓶式、活塞式和皮囊式三种。蓄能器的功能主要是能够释放出多余的压力能，从而让机器在工作的效率上达到最高，那么蓄能器具体有哪些作用呢？

1、在安装的时候应该垂直安装，这样能够最大发挥其效用，如果实在是没有办法的话，可以适当的允许倾斜一点。皮囊式蓄能器的皮囊强度不高，不能承受很大的压力波动，且只能在-20摄氏度~70摄氏度的温度范围内工作。
At the time of installation should be installed vertically, this can maximize its effectiveness, if it is no way you can allow the proper tilt point. Bladder Accumulator bladder strength is not high, can not withstand a lot of pressure fluctuations, and can only work within the -20 degrees C to 70 degrees C temperature range.
2、装在管路上的蓄能器须用支板或支架固定。蓄能器与管路系统之间应安装截止阀，供充气、检修时使用。蓄能器与掖泵之问应安装单向阀，防止液压泵停车时蓄能器内储存的压力油液倒流。
Installed in the pipeline accumulator shall be fixed by the support plate or bracket. Should be installed between the accumulator and the pipeline system shut-off valve for inflatable, use and maintenance. Accumulators and tuck pump check valve of the question should be installed to prevent parking in the accumulator when the hydraulic pressure of the oil stored in back.
3、吸收系统脉动，缓和液压冲击。蓄能器能吸收系统压力突变时的冲击，也能吸收液压泵工作时的流量脉动所引起的压力脉动。
Pulsation absorption system, easing hydraulic shock. Accumulator system pressure can absorb shock when mutated, can absorb the pressure pulsation flow pulsation pump at work caused.
4、作辅助动力源。在问歇工作或周期性动作中，液压升降机蓄能器可以把泵输出的多余乐力油储存起来。当系统需要时，由蓄能器释放出来。这样可以减少液压泵的额窄流量，从而减小电机功率消耗。
As an auxiliary power source. Work in intermittent or cyclical movements, the hydraulic lift accumulators can force the extra oil pump output music store. When the system needs, released by the accumulator. This can reduce the amount of narrow flow pump, thereby reducing electrical power consumption.
5、系统保压或作紧急动力源。对于执行元件长时间不动作，而要保持恒定压力的系统，可用蓄能器来补偿泄漏，从而使压力恒定。对某些系统要求当泵发生故障或停电时，执行元件应继续完成必要的动作时，需要有适当容量的蓄能器作紧急动力源。
System holding pressure or for emergency power source. For a long time the actuator does not operate, and to maintain a constant pressure system, the accumulator can be used to compensate for the leakage, so that the pressure constant. When some systems require that when a pump failure or power outage, the actuator should continue to complete the necessary action, the need for adequate capacity accumulator for emergency power source.
