Hydraulic accumulator products rely on other media for conversion

Since the energy accumulator product is non-compressible liquid, the working oil cannot accumulate pressure energy, and the pressure energy can be changed by other media.You have to accumulate.For example, a balloon charge accumulator developed using the compressibility of a gas (nitrogen) is a device for storing working oil.

The capsule accumulator consists of an oil part and a gas part with a gas seal. The oil around the leather bag is connected to the oil circuit.The higher the pressure is, the oil will enter the accumulator. The wholesale gas in the hydraulic capsule accumulator will be compressed, and the pressure in the system pipeline will no longer rise.When the pipeline pressure drops, the compressed air expands and oil is pressed into the circuit, thus relieving the pressure drop in the pipeline.The compression spring converts the overpressure in the hydraulic system to the spring potential and releases the pressure as needed.

It has simple structure and low cost.However, the spring expansion is limited, and the spring expansion is not sensitive to pressure change, poor vibration attenuation function, so small capacity, low pressure system (P≤1).0?The "input field" in the list applies only to 2MPa) or as a buffer.The advantages of gas-liquid direct contact accumulator filled with inert gas are large capacity, sensitive response, small inertia of the moving part and no mechanical wear.However, due to direct gas-liquid contact, the size is small and the inflation pressure is limited.Sealing is difficult and gas phase mixing is possible.

Therefore, stainless steel capsule accumulator wholesale such accumulator gas consumption is relatively large, components easy to cavitation corrosion, volume utilization is low.There is a seal between the piston and the inner wall of the cylindrical accumulator. The oil is not easy to oxidize. This accumulator has a long life, light weight, simple installation, simple structure, convenient maintenance, poor response sensitivity, and is not suitable for low pressure absorption pulse?The accumulator is mounted with two hemispherical shells with a rubber film sandwiched between the two hemispheres.Weight to volume ratio is the smallest, responsive, low pressure pulsation removal effect is obvious.Diaphragm type energy storage rubber film area is small, gas expansion is limited, gas pressure is limited, small capacity
