The invention discloses a
broadband gas-liquid two-phase spring pulsation
damper which comprises parts including an inlet end communication body, a sealing ring, a buffer cap, a body, a rubber spring or corrugated
pipe spring, a flow passing net
barrel, an outlet end communication body and the like. According to pulsatile fluid flowing through the inlet end of the
broadband gas-liquid two-phase spring pulsation
damper, fluid
peak value kinetic energy is transmitted to the rubber spring or corrugated
pipe spring in the body through end flanges of the buffer cap and the flow passing net
barrel, and the rubber spring or corrugated
pipe spring generates elastic deformation to absorb pulsation
kinetic energy; and when a fluid
peak value comes, the rubber spring or corrugated pipe spring releases
stored energy and recover deformation. Through circulated reciprocation of the above process,
fluid pressure pulsation is restrained. The
broadband gas-liquid two-phase spring pulsation
damper is suitable for fluid pulsation eliminating of liquid flow and gas flow within the 0-80Hz pulsation frequency range. The broadband gas-liquid two-phase spring pulsation damper has the obvious effects of being simple in device structure, small in size, light and high in bearing pressure compared with a traditional damper, and the pulsation eliminating rate is 95% or above.
