Precautions for the installation of high-speed centrifuge

The installation of the centrifuge needs to meet the requirements, in order to carry out the normal operation in the subsequent operations, such as the installation of the power supply, as well as the balance of the installation, and the installation of the rotor. The following Shanghai Lixinjian centrifuge manufacturers give you simple Introduce the details of the details of the installation of high-speed centrifuges .

`correct installation

a power supply voltage: voltage fluctuations should meet the national standard of less than 10%, otherwise some manufacturers of centrifuges can not operate normally. If the voltage fluctuation is above this, it is recommended to use a voltage regulator to comply with this grid.

b ground wire should be firmly: the wiring of the power supply of the room should meet the requirements. China is a three-phase four-wire system. The three-phase is the three-phase in the industrial power. When the three-phase electricity is used, the neutral line is separated from the ground line. More importantly, whether it is three-phase industrial power or not, the general single-phase power is good, and the ground line should be reliable to avoid leakage. The ground wire cannot be connected to the hot air pipe or the water pipe.

c The ground should be flat and firm: for large centrifuges, the floor should be firm at the installation site to ensure that the rotor of the centrifuge works normally, without recessing, and the ground at the installation and fixing should be flat and firm.

d Find a good level: Find a small level with a correct level, open the lid of the centrifuge, find the level on the spindle, and find the level by adjusting the twisting of the adjusting bolt next to the four casters, and pay attention to one of the feet can not be lost.

`Loading to find balance

In the design and manufacture of the centrifuge, the imbalance caused by the machining error of the rotor has been remedied by the dynamic balance test, but all centrifuges have the unloading amount of the sample.

Centrifuge manufacturers strive to give larger values ​​in order to compete with other manufacturers on the maximum unbalance limit allowed by the centrifuge. At this larger value, the centrifuge can be operated, but the imbalance force generated at this time suddenly hits the bearing and the bracket at n times per minute, and the centrifuge is damaged. Therefore, users should try to find a good balance and centrifuge for those expensive centrifuges, which is good for the life of the centrifuge.

`Clean up the water in the centrifuge chamber

When the centrifuge is running, it uses refrigeration. Because of the moisture of the air, it is frosted in the centrifugal chamber, and after the shutdown, it is frosted into water. Most foreign low-speed large-capacity centrifuges have no drainage holes, and the water in the centrifugal chamber is more and more accumulated. At this point, the user should remove the rotor and clean up the accumulated water. When reinstalling the rotor, be sure to install it to avoid accidents.

`Broken shaft accident

The rotor is not placed well, or the sample imbalance is too large, and the centrifuge starts. Modern imported centrifuges have unbalanced protection, that is, when the unbalance amount exceeds a certain limit, the power should be automatically cut off to stop the centrifuge. However, under the above circumstances, it is already late, and a serious accident will occur. One of the malignant accidents is the broken shaft. Due to the sudden break of the shaft during high-speed rotation, the centrifugal rotor has no support, and the centrifugal machine is turned into a chaotic collision, which can make the centrifuge rotate the machine to a 270° angle. At this time, if there are staff or equipment next to it, it will cause accidents and deaths of the staff and damage to the equipment.

The above is the correct installation of the high-speed centrifuge , do you understand clearly?
