The invention discloses bag accumulator equipment. The bag accumulator equipment comprises a nitrogen gas cylinder, a reducing valve, a gas charging system and a bag accumulator which are sequentially connected, wherein the bag accumulator is provided with a threaded inlet pipe; the gas charging device comprises a cylindrical connector socket, a cover cylinder, a pressure gauge, a temperature transmitter and a gas tube with a check valve arranged at the outer end, wherein a central hole is longitudinally formed in the cylindrical connector socket, and an annular groove is formed in the end surface of one end of the cylindrical connector socket; the cover cylinder is clamped in the annular groove and matched with the threaded inlet pipe; gas ports of both the pressure gauge and the temperature transmitter communicate with the central hole; the inlet end of the check valve is in threaded connection with the outlet end of the reducing valve; a radial screw hole is formed in the other side of the cylindrical connector socket, and external threads matched with the radial screw hole are formed at the outer end of the gas port of the pressure gauge; and an axial inner screw hole is formed in the other end of the cylindrical connector socket, the gas port of the temperature transmitter is provided with a protective tube, and external threads matched with the axial inner screw hole are formed at the outer end of the protective tube. The problems in the prior art that the pressure and the temperature in bag accumulator equipment cannot be known at any time and the charging pressure during gas charging for the bag accumulator equipment is difficult to control are solved.
Description
technical field [0001] The invention relates to a bladder type energy storage device. Background technique [0002] The accumulator is an energy storage device in the hydraulic and pneumatic system. When the system pressure increases, the energy in the system is converted into compression energy or potential energy and stored. When the system needs it, the compression energy or potential energy is converted into It is released for hydraulic or pneumatic energy, and the supply system is replenished to ensure that the pressure of the entire system is normal. When the operating pressure of the accumulator is low, it is often necessary to inflate to increase the pressure. Nitrogen is the first choice for accumulator inflation gas because of its stable physical and chemical properties, easy manufacture, and low price. Since the pressure of the nitrogen cylinder is 14Mpa and the nitrogen filling pressure of the accumulator is 0.15Mpa, the pressure of the nitrogen cylinder is far ...
