1. The service life of bladder accumulators is generally shorter (compared to piston accumulators ), and the quality of bladder accumulators varies greatly among different brands;

　　2. Many factors can lead to reduced service life and cracking of gas cylinders, including differences in the quality and service life of the gas cylinders themselves, improper operation of gas cylinder installation procedures (such as failure to pre-lubricate), improper operation of pre-inflation procedures (such as failure to slowly inflate), pre-inflation pressure errors, inlet flow rate approaching or exceeding 7m/s, reciprocating time approaching or less than 10 seconds when used for energy storage, collision between the gas cylinder and the valve during operation, large temperature variations (including large seasonal temperature differences), prolonged horizontal vibration and shaking, liquid corrosion, and destructive inertial torque of tiny solid sediments within the chemical substance.

　　3. When the gas cylinder cracks, it is highly likely to cause the accumulator to suddenly fail. In addition, the gas explosion of the car's fuel tank and fuel pump may cause safety accidents or damage to maintenance and standby.

　　4. The volume of the gas cylinder should not be too large, otherwise it will shorten its lifespan. The British ASME standard generally recommends a maximum of 60 liters.

　　5. The working pressure should not be too high. In my country, the maximum safety performance (3 times or less) is generally 31.5 MPa, and for pneumatic accumulators (4 times the safety performance) it is 51.8 MPa.

　　6. When rapidly releasing gear oil, the bladder accumulator's spool valve is highly likely to close prematurely, causing the accumulator to suddenly and temporarily fail.

　　7. Because the raw material of the gas is plastic, its tensile strength is not high and it cannot withstand very large pressure fluctuations (note the gas engine compression ratio). Excessive fluctuations will significantly reduce the service life of the gas.
