Circulating type particle damping vibration isolator and assembling method thereof

The invention discloses a circulating type particle damping vibration isolator and an assembling method thereof. The circulating type particle damping vibration isolator comprises an upper supporting frame, a lower supporting frame, a compression spring, a magnetic drive pump, a particle tank, a double-screw elevator and a ball screw pair. The upper supporting frame is connected with mechanical equipment, and the lower supporting frame is connected with a foundation. The other end of the compression spring is connected with the lower supporting frame; the ball screw is fixed to the upper supporting frame and spirally inserted into a center hole of the magnetic drive pump, and the magnetic drive pump is fixed to the lower supporting frame through a bolt. The particle tank is filled with particles, the double-screw elevator is used for adjusting the volume of the particle tank, and the magnetic pump is connected with the particle tank through a hose. The vibration isolator is simple in structure and convenient
