升降機蓄能器主要有彈簧式和充氣式兩大類，而充氣式又包括氣瓶式、活塞式和皮囊式三種。蓄能器的功能主要是能夠釋放出多余的壓力能，從而讓機器在工作的效率上達到最高，那么蓄能器具體有哪些作用呢？
1、在安裝的時候應該垂直安裝，這樣能夠最大發揮其效用，如果實在是沒有辦法的話，可以適當的允許傾斜一點。皮囊式蓄能器的皮囊強度不高，不能承受很大的壓力波動，且只能在-20攝氏度~70攝氏度的溫度范圍內工作。
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、裝在管路上的蓄能器須用支板或支架固定。蓄能器與管路系統之間應安裝截止閥，供充氣、檢修時使用。蓄能器與掖泵之問應安裝單向閥，防止液壓泵停車時蓄能器內儲存的壓力油液倒流。
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、吸收系統脈動，緩和液壓沖擊。蓄能器能吸收系統壓力突變時的沖擊，也能吸收液壓泵工作時的流量脈動所引起的壓力脈動。
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、作輔助動力源。在問歇工作或周期性動作中，液壓升降機蓄能器可以把泵輸出的多余樂力油儲存起來。當系統需要時，由蓄能器釋放出來。這樣可以減少液壓泵的額窄流量，從而減小電機功率消耗。
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、系統保壓或作緊急動力源。對于執行元件長時間不動作，而要保持恒定壓力的系統，可用蓄能器來補償泄漏，從而使壓力恒定。對某些系統要求當泵發生故障或停電時，執行元件應繼續完成必要的動作時，需要有適當容量的蓄能器作緊急動力源。
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.
