Tubular centrifuge has high flexibility

Tubular centrifuge is a new type of machine with high filtration performance developed in recent years. Its drum shape is more special than that of ordinary centrifuge. At present, there are few strength algorithms for this kind of drum. In view of this, the axisymmetric finite element stress analysis method is used to study the overall optimization calculation of the siphon centrifuge drum, that is, the thickness of the drum body, liquid barrier plate, drum bottom, siphon chamber wall and overflow plate and other related components are optimized, and the corresponding optimization calculation mathematical model is established.

Before each use, pay attention to check whether the rotor has corrosion points and fine cracks. It is forbidden to use the rotor with corrosion or crack, and use the rotor beyond the warranty period to ensure personal safety. When using the centrifuge rotor, make sure that the rotor number set is correct. If the rotor number is set incorrectly. It will cause the rotor to overspeed or not reach the required centrifugal effect. In particular, the use of overspeed may lead to a serious accident of rotor burst, which should not be neglected.

In the case of no need for high centrifugal force, the horizontal rotating head has unique advantages. The horizontal swivel is composed of the swivel itself and the basket. The basket can accommodate the adapter of various types of test tubes, so it has high flexibility without changing the swivel head. In the process of centrifugation, the basket is thrown out and is in the horizontal position. All the precipitates are located at the bottom of the test tube, while the sample centrifuged by a fixed angle rotating head is always located on one side of the test tube at a certain angle. Therefore, horizontal rotation is more conducive to the recovery of samples. In addition, when the horizontal rotating head stops centrifugation, the test tube is always in the vertical direction, so it is very convenient to take out the test tube, and it is not easy to cause the sample to be resuspended; in the fixed angle rotating head, because the position of the test tube has a certain angle, it is necessary to be more careful to avoid re suspension.

The strong centrifugal force produced by the high-speed rotation of the rotor of the tubular separator accelerates the settling speed of the particles in the liquid, and separates the substances with different sedimentation coefficient and buoyancy density in the sample. Therefore, it is necessary to use centrifuge to produce strong centrifugal force to force these particles to overcome the diffusion and produce sedimentation movement. Centrifuge is the use of centrifugal force, the separation of liquid and solid particles or liquid and liquid mixture of components of the machinery. Centrifuges are mainly used to separate the solid particles in suspension from the liquid; or to separate two kinds of liquid with different density and mutual immiscible in the emulsion (such as separating cream from milk); it can also be used to remove the liquid in the wet solid and dry the wet clothes with washing machine; the production scale and quality of centrifuge manufacturers determine the development of centrifuge industry. There are many domestic centrifuge manufacturers and a large production team, but most of them are small-scale production. They only pursue enterprise profits and development, and the investment in technology research and development and update is very small, which restricts the development of the industry. Without new technology, the development of centrifuges will stop. In other words, the research and development of technology needs a lot of cost, human and financial resources are time It can be said that most domestic manufacturers do not have the capacity to invest in scientific research for a long time.
