Three-column centrifuge

Abstract

The invention discloses a three-column centrifuge and relates to the technical field of centrifuges. The three-column centrifuge comprises a machine case, a rotary disk, a rotary drum, a connecting rod, a base, a damping device, a speed changer and a motor. The damping device comprises supporting blocks, springs and telescopic shafts. The telescopic shafts are fixedly connected between every two supporting blocks. The bottom of the machine case is fixedly connected to the tops of the supporting blocks. The base is fixedly connected to the bottoms of the supporting blocks. A back-up ring is arranged at the bottom of the interior of the machine case. Roll balls are embedded in the back-up ring. A balance ring is further mounted at the upper end of the rotary drum. The balance ring contains equilibrium liquid. According to the three-column centrifuge, the damping device is arranged at the bottom of the machine case; the operation stability of the three-column centrifuge can be effectivelyenhanced; the service life of equipment is prolonged; the operation stability of the three-column centrifuge is further improved through the balance ring, the back-up ring and the roll balls, and theservice life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to a three-legged centrifuge. Background technique [0002] When the general three-legged centrifuge is working, due to the unsatisfactory shock absorption effect of the centrifuge itself, the centrifuge will cause a large vibration when it is working, which will affect the service life of the centrifuge.
