Description

Positioning centrifugal machine

Technical Field

The utility model discloses a centrifugal machine with a positioning function, belongs to the technical field of centrifugal machines, and particularly relates to a positioning centrifugal machine.

Background

The centrifugal machine uses the powerful centrifugal force generated by the high-speed rotation of the rotor to accelerate the sedimentation velocity of particles in the liquid and separate substances with different sedimentation coefficients and buoyancy densities from the sample. It is necessary to use a centrifuge to generate a strong centrifugal force to force the particles against diffusion to create a settling motion.

The centrifuge is typically driven by an electric motor. After the suspension (or emulsion) is added into the balancing barrel, the suspension (or emulsion) is quickly driven to rotate at the same speed as the balancing barrel, and the components are separated under the action of centrifugal force and are respectively discharged. In general, the higher the balance tub rotation speed, the better the separation effect.

However, acceleration and rotation speed of the centrifugal machine in the prior art are usually set by people or a system, and the motor works according to setting data, so that the working mode cannot realize full-automatic work; and the speed of acceleration and rotation speed directly influence the state of the product, and the product failure can be caused by too high or too low speed.
