No spark is generated when the metal collides with the metal is suitable for flammable and explosive environments. Has an operating characteristic similar to an air spring, but has no gas leakage.
Background
The energy accumulator is an energy storage device in a hydro-pneumatic system, which converts the energy in the system into compression energy or potential energy to be stored at proper time, when the system is needed, the compression energy or potential energy is converted into energy such as hydraulic pressure or air pressure to be released, and the energy is supplied to the system again, when the instantaneous pressure of the system is increased, the energy accumulator can absorb the energy of the part, so that the pressure of the whole system is ensured to be normal. Accumulators have two uses: when the load demand flow is greater than the hydraulic pump flow, the liquid is released from the accumulator to make up the shortage of the hydraulic pump flow; when shut down, but still maintaining a certain pressure, the hydraulic pump may be stopped and the leakage of the system compensated by the accumulator to maintain the pressure of the system. The accumulator may also be used to absorb pressure pulsations of the hydraulic pump or to absorb hydraulic shock pressures generated in the system. The pressure in the accumulator can be generated by compressed gas, a weight or a spring, and accordingly the accumulator is classified into a gas type, a weight type and a spring type. The existing spring energy accumulator is heavy, large in size, large in noise and unstable in amplitude, and needs a piston to seal and isolate, so that once the sealing fails, the spring energy accumulator cannot work.
