1、辅助能源 Auxiliary power source 如果在液压回路中短时间内流量变化较大，使用蓄能器就能用较小的泵和电机，从而降低了设备费用和操作费用。 如图所示的运行周期会需要一个具有Q2流量的泵。如果应用蓄能器，在时间周期（t2-t1）和（t4-t3）内蓄油，因此此时需要的油流量很小，或者甚至不需要用油。当所要求的流量高于泵送量Q1时，在t1和t3-t2周期内可使用蓄能器供油。选择泵送量Q1须满足v1+v2≤v3+v4。 If in a short period of time in the hydraulic circuit the amount of flow what changes is larger, application accumulator then you should be allow choosing a smaller pump and motor used of Thus reducing equipment costs and operating costs. what shows the operation cycle needs a pumps flow of Q2. Accumulator, if applied in the time cycle (T2-T1) and (T4-T3) within oil accumulator, because at this time needs for a little flow of oil, or even zero. While needed to flow volume is higher than the capacity rate of pump transport Q1, in the cycle of T1 and T3-T2 can use accumulator for supplying oil. If selecting the transportation capacity of pump(Q1.) it has to consider meet the use volumes of V1+V2≤V3＋V4. |

2、吸收脉动Pulsationdamper 活塞和隔膜泵在运行时会在液压回路里不可避免地产生脉动，这即不利于运行又不利于部件的使用寿命。 在靠近泵的压力侧装上胶囊蓄能器，可缓和振动，使振动降到满意的程度。典型的用途如可用于定量泵及活塞数较少的柱塞泵等。 Both of piston & diaphragm pumps in the run-time in the hydraulic circuit of the pulse generated is inevitable, for this condition not conducive to normal operation of equipment is not conducive to life of relation parts. Near the outlet of the pump installed a bladder accumulator which can absorb system pulse, meanwhile achieve a desiring degree . The typical application way: it be used to the dosing pump or the piston pump of keeping a small quantity pistons etc. |

3、紧急动力源Emergency energy reserve 在动力突然损失的情况下，例如管道或接头故障、泵破损等，蓄能器能够提供足够的能够的能量来完成运行循环或是传动机构、阀门等重新恢复到安全位置，从而防止损坏设备或产品。 另外在一些情况下时必须的获得紧急动力源，如为关闭安全门、电器开关、安全阀、紧急制动器等所需要的液动源。 另一个典型用途是将燃油紧急提供给电厂的锅炉。图5表示的B处的引起能量损失的故障可通过手动操作电子阀A而消除，这时就使用蓄能器储备的能量。 Under the case of power lost suddenly, for example: the fault came from the pipeline or joint pump damaged etc, in order to prevent damage to equipment or products, the accumulator can provide sufficient energy to complete running cycle or reset a safety position with transmission system and valve etc. Under the case of emergency power source had to be obtained, for example; close up the safety door , electrical switch, safety valve, hydraulic power source what is the arrester of the emergency needs. Other one typical purpose is supplying fuel oil to the boiler of power mill peremptorily. FIG5 B illustrates is causing a failure of energy loss, it be avoid by operating the electron Valve A with manual wise,here it is using an storage energy what came from accumulator. |

4、容积补偿Volume Compensator 在闭式液路中，由于热膨胀，温度的上升会导致压力上升。 在线安装的蓄能器可补偿油的容积变化，从而保护阀门、垫片、压力表等不出故障。炼油厂和远距离油管有其典型的用途。 In a closed hydraulic circuit, thermal expansion can cause an increase in pressure due to a rise in temperature. An accumulator installed in the line will protect the valves, gaskets, Pressure gauges etc. common applications are found in refineries and pipelines. |

5、压力补偿Pressure compensator 当长期需要恒定静态压力时，蓄能器是必不可少的，因为它将补偿由于接头、密封等渗漏而造成的压力损失，而且能平衡可能在运行循环过程中发生的压力高峰。典型用途为夹紧系统，负载平台、筑路压力机、床、润滑系统等。 When a constant static pressure is required for a long period, an accumulator is indispensable as it will compensate for pressure loss due to seepage through joints, seals etc. as well as balancing pressure peaks which may occur during the operating cycle. Typical applications are found in closing systems, fig.6, loading platforms, curing presses, machine tools, lubricating systems, etc.. |

6、配重Counterbalancing 平衡一个力或重量可以通过由蓄能器驱动的液压活塞来达到，从而避免了配重占地，并减轻了重量。典型的用途为机床，卷扬机等。

7、吸收冲击Hydraulicline shock damper 快速阀门的关闭会产生冲击波（水锤现象），导致管子、接头、阀等部件的损坏。 使用适当的蓄能器能大大地减少冲击。典型用途为水管、燃油和油的远距离管路、洗涤设备等。 Rapid valve closure can produce shock waves (water hammer) resulting in over pressurization of pipes, joints, valves etc. The use of a suitable accumulator can neutralize or significantly reduce the shock. Typical applications are water, fuel and oil distribution circuits, washing equipment etc. |

8、吸收脉动Shock absorber 液压设备中的机械振动能被蓄能器吸收。可用于叉式提升机的驱动和悬挂系统、移动吊车、石块破碎机等。 Mechanical shocks in hydraulically driven equipment can be absorbed by accumulators. Possible applications are in drive and suspension systems for fork-lifts, mobile cranes, agricultural and civil engineering, machinery etc. |

9、液压弹簧Hydraulic spring 囊式蓄能器能取代机械簧，例如用于深冲压的模具装置。在不需使用弹簧的情况下，通过调节油压就能更容易地、更精确地在较大范围内调节模具压力。 The accumulator can be used with advantage as an alternative to mechanical springs, e.g. deep drawing .The thrust can be easily controlled to great accuracy over a wide range of pressures by oil pressure control without the need for springs or support. |

10、流体传输Fluid separator (transfer barrier) 在一个系统中，当作用在回路一侧的液体压力增加必须转换到回路另一侧液体中，而又不使两种液体有混合现象时，胶囊蓄能器可有效地解决这一问题。蓄能器的胶囊犹如一个挠性屏蔽作用于液体或气液之间，提供瞬时响应而不减小系统的压力。 In a system where fluid pressure developed on one side of the circuit must be transferred, as developed, to another fluid without any possibility of the two fluids intermixing, the bladder accumulator provides the satisfactory solution . The accumulator bladder acts as a flexible barrier between the fluids or between a gas and a fluid providing instantaneous response without reducing the system pressure. |
