technical field

The utility model belongs to the technical field of damping equipment, in particular to a damping base and a centrifuge with the damping base.

Background technique

A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. During the working process of the centrifuge, due to the continuous movement of the raw materials inside the body, the body will shake to a certain extent. At this time There will be a hard impact between the centrifuge and the base, which will cause vibration and noise between the base and the ground. At present, the centrifuge usually installs a damper on the base to attenuate the vibration during the working process. However, during the operation of the centrifuge, there will be Torsion, the damper can only attenuate the vertical impact, and the torsion will cause the piston rod to break. Based on this, our company has developed a shock-absorbing base and a centrifuge with a shock-absorbing base to replace the existing technology.
