Classification of the centrifuges head assembly

The centrifugal force is used to speed up the separation of different materials which need to be separated. The centrifuge is widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping and other departments.

The main principle of filter centrifuge is generated by the high-speed operation of the centrifugal drum centrifugal force (with appropriate filter), solid-liquid mixed liquid in the liquid accelerated thrown out from the drum, and the solid phase in the drum to the effect of separation of solid and liquid, or commonly known as dehydration effect.

The main principle of the sedimentation centrifuge is the strong centrifugal force generated by the high speed rotation of the rotor. The settling velocity of different specific gravity components (solid phase or liquid phase) is accelerated, and the material of different settlement coefficient and buoyancy density of the sample is separated.

Centrifuge is widely used in mineral processing, coal, water treatment and shipping and other departments.

Choose centrifuge required under suspension (or emulsion) of solid particles size and concentration, solid and liquid (or two liquids) density, liquid viscosity, residue or sediment characteristics. May refer to "the selection and safety of the centrifuge [selection guide].".

Low speed centrifuge literally is often speed relatively slow centrifuge, today Xiaobian say, if you just simply think it will cause errors, because of low speed centrifuge is not all because of the low speed, mainly because the rotating speed of the rotor is slow, so is related to the rotor; the other is the because the test items of essential requirements or test requirements, so the two decided the low speed centrifuge.

When low-speed centrifuge rotor rotates at a high speed, air friction heat, rotor temperature will rise and tube in the sample temperature will rise. As biological samples are sensitive to temperature. The temperature of the centrifugal test is usually 4. Without the intelligent technology of computer control, it is impossible to achieve the accuracy of L. Therefore, the cooling of the centrifugal chamber with a cooling machine, and to achieve the purpose of cooling the rotor, the temperature of the sample. But the actual temperature of the rotor is very difficult, and the temperature sensor is used to measure the temperature of the rotor in the centrifugal chamber at home and abroad. Here T =T cavity T compensation. T compensation is related to the type of the rotor, the speed and the running time. Low speed centrifuge voltage fluctuation to meet 10% less than the national standard, if the voltage fluctuation on the above, it is recommended to use the regulator, the wiring of power to meet the requirements, should use three-phase power zero line and the ground separately, more important is whether industrial three-phase or, generally of a single-phase or, the ground should be reliable, so as to avoid leakage.

As a means, the centrifuge has many advantages. For example, the speed of the centrifuge can be operated at low temperature, which can protect the activity of the biological macromolecules. The load of the centrifuge is large, and the sample can be separated and purified at a time, and the sample is much larger than that of chromatography and electrophoresis. Analysis of the molecular weight of the centrifuge can not only measure the material, but also to test the purity of the material, conformation, sedimentation coefficient, etc.. As a result, the most convenient and effective tool for the separation and purification of cells, proteins, nucleic acids, enzymes and viruses is the most convenient and effective method for the separation and purification of cells, proteins, nucleic acids, enzymes and viruses. spinneret draft
