The design principle of the centrifuge is to use the centrifugal field force generated when the rotating head rotates to accelerate the sedimentation speed of the sample particles and separate substances with different sedimentation coefficients or buoyant densities in the sample.In addition to rotations per minute (r/min) and centrifugal (rotation) radius, the factors that determine the size of the centrifugal force are also related to the influence of the forces of the particles (gravity, buoyancy, friction).Rotational motion, centrifugal force.The direction is perpendicular to gravity, so the relative centrifugal force (R0) is used, which is the centrifugal force acting on the rotating particle relative to gravity, and the gravitational acceleration g (980cm/s) is used as the amplitude, also known as 'g-Force'.', the expression is: RCF=o)~/980. The key to centrifugation is how to determine the centrifugal force, speed and centrifugation time settings based on the properties of the sample particles and media and the technical parameters of the rotor. The sedimentation or separation rate of the particles (collectively known as cells, organelles and macromolecules) depend on the

1. The centrifuge vibrates violently when it is working. Please stop it and check. First close the feed valve and then close the host button. Is it caused by mechanical reasons or uneven materials?The cause must be eliminated before starting the machine!Start nitrogen replacement before starting up, and then turn on the host.2. If there is an abnormality when the centrifuge is working, please close the feed valve first, then close the main unit button, find out the cause, eliminate the fault and then turn it on again.Nitrogen replacement must be turned on before starting up, and then turn on the host.

A fully automatic centrifuge generally consists of a centrifuge host, an automatic feed valve, an automatic washing valve, a hydraulic station, and a PLC frequency conversion cabinet. When selecting a fully automatic centrifuge for material separation, you need to pay attention to: 1. Ensure that the reaction sign is in the pipeline between the centrifuges. smooth.Because the fully automatic centrifuge works intermittently, when the feed is stopped, the feed valve of the fully automatic centrifuge will automatically close to stop feeding. Therefore, if the material is easy to precipitate, you need to consider the bottom of the kettle and the automatic feed valve. Add backflush or other measures to solve the pipe blockage caused by material precipitation and affect the next batch of work.2. When installing the fully automatic centrifuge, the foundation needs to be raised. The foundation can be a steel frame structure or a concrete structure.If a concrete structure is used, it is recommended to embed iron plates at four positions of the centrifuge shock absorber to facilitate the welding of the shock absorber and the embedded iron plates during installation of the centrifuge. You can also consider using anchor bolts to connect the fully automatic centrifuge.3. Fully automatic centrifuge
