Centrifuge is a mechanical device that uses centripetal force to separate the components of liquid and solid particles or liquid and liquid compounds.
The centrifuge is mainly used to separate the solid particles in the liquid mixture from the liquid; Or separate two liquids with different relative densities and miscible with each other in the emulsion (for example, fresh milk oil is separated from milk); It can also be used as a liquid in the wet solid state, such as drying wet clothes and trousers with a washing machine; The unique speed limiting tubular separator can also separate vapor compounds with different relative densities; Using the characteristics that solid particles with different relative density or particle size distribution have different settling velocities in liquid, some ground settlement centrifuges can also classify solid particles according to relative density or particle size distribution.
Centrifuges are widely used in chemical plants, crude oil, food, pharmaceutical industry, mineral processing plants, coal, sewage treatment and ships.
What are the operation steps of the centrifuge? What are the common problems in the whole process of application? Let me give you a detailed introduction.

What are the operation steps of the centrifuge? What are the common problems of the application?
1. When applying various centrifuges, be sure to balance the centrifuge tubes and their contents with high precision on the balance scale in advance. The difference in net weight during balancing must not exceed the scope required in the instructions for use of each centrifuge. Each centrifuge has its own allowable error for different torsion heads. Odd number of pipes must not be loaded in the torsion heads. When only part of the torsion heads are loaded, the pipes must be symmetrically placed in the torsion heads, So that the load is evenly distributed around the periphery of the torsion head.
2. If you want to filter at a temperature lower than the indoor temperature. Before application, the torque should be placed in the refrigerator or the torque room where the centrifuge is placed for quenching.
3. Do not leave randomly during the whole process of suction filtration. Check whether the instrument panel on the centrifuge is in normal operation at any time and anywhere. If there is any abnormal sound, shut down the centrifuge immediately for inspection and fault detection.
4. If there is 0.00 or other data in the application, and the equipment does not run, it should stand by and turn off the power supply, and start again after 10 seconds. After the set speed ratio displays information, press the run key again, and the equipment will still run.
5. If the proportion of the sample to be separated exceeds 1.2 g / cubic decimeter, the high-speed rotation n must be adjusted by pressing and holding: n = nmax * (1.2 / sample proportion) 1 / 2, nmax = motor rotor limit speed ratio.
6. Do not open the cover door during the whole operation of the equipment or when the motor rotor is not stopped to prevent safety accidents.
7. The suction cup must be equal to the grouting sample, and it is not necessary to make the torsion not operate in a balanced condition.
8. It is not necessary to operate the centrifuge for more than one hour at a time.
9. Reliable grounding device for centrifugal maintenance; If the device is not used, please unplug the power cord.
