China Low Temp Chiller is a kind of high-tech instrument routinely used in the laboratory and has wide applications. When selecting the type of China Low Temp Chiller, multiple references are needed. China Low Temp Chiller is a rather special instrument, and there are certain safety hazards when it is in use. Therefore, ensuring the mechanical safety and user safety of China Low Temp Chiller is of vital importance!

When purchasing China Low Temp Chiller, several points should be noted:

First, it is emphasized that bearings need to be configured.

China Low Temp Chiller belongs to high-speed chemical equipment. High speed requires the use of good bearings. Genuine bearings can ensure the long-term normal operation of China Low Temp Chiller, with a service life of up to more than 10 years.

Second, it is necessary to pay attention to maintaining the lubrication of the machinery and use high-temperature lithium-based grease. The quality of lithium-based grease is another major cause of bearing overheating. In addition, a detailed inspection should be carried out. If mechanical friction is accompanied by noise and there is obvious wear on mechanical components, it indicates that the bearing is loose. In this case, there should be a problem with the bearing and it needs to be replaced.

Thirdly, whether the concentricity of the main shaft of China Low Temp Chiller is accurate. Under normal circumstances, users do not pay much attention to the concentricity. A large tendency of the main shaft concentricity can easily cause the bearing to overheat.

The safe usage requirements of China Low Temp Chiller:

1. The selection must be correct.

2. Use the China Low Temp Chiller within the prescribed scope. The general-purpose China Low Temp Chiller must not be used in flammable, explosive or corrosive environments.

3. Operate in accordance with the prescribed operating procedures. Abnormal braking, overloading or overspeed operation are strictly prohibited.

4. Faults should be eliminated in time. Faulty China Low Temp Chiller shall not be operated, and failed China Low Temp Chiller shall be scrapped in time.

5. Install, use and maintain the China Low Temp Chiller in accordance with the requirements in the product user manual. Do not modify the components of the China Low Temp Chiller by yourself, and do not increase the rotational speed of the China Low Temp Chiller by yourself.

6. Formulate corresponding rules and regulations for the installation, use and maintenance of China Low Temp Chiller and strictly implement them to achieve the goal of safe use.

It is normal for the components of China Low Temp Chiller to heat up because some energy is consumed during use. However, if it heats up excessively, attention should be paid. Check if there is a problem somewhere and deal with and solve it in time. Only in this way can China Low Temp Chiller be used better.

When we are using the China Low Temp Chiller in the laboratory, we should avoid some unnecessary problems, so as to be helpful for our operation and use of the China Low Temp Chiller in the laboratory.

When we place the centrifuge tubes, they must be symmetrical so that the China Low Temp Chiller can operate normally and will not generate high-level vibrations. Before opening the China Low Temp Chiller, the door cover of the China Low Temp Chiller should be closed. This cannot be forgotten. Whether it is on or off the China Low Temp Chiller, there should be a certain control over the speed. Let the machine accelerate or decelerate slowly. Do not adjust the amplitude too much at once to avoid affecting the usage effect and service life of the machine.

When starting up the China Low Temp Chiller in the laboratory, the rotational speed of the machine should be checked to see if it is within the range corresponding to the rotational speed of the rotor. Of course, it is also necessary to check whether the rotor parts are loose, the condition of the circuit connection, whether the power supply is normally connected and other inspection work before starting up. If there is abnormal shaking or sound, the machine needs to be stopped immediately for inspection, and corresponding records should also be made. Before using the China Low Temp Chiller, its braking device should also be adjusted properly. If the rotor of the China Low Temp Chiller exceeds the corresponding speed when rotating, it needs to be shut down. When the rotor is in operation, the machine must not be disassembled or adjusted.

China Low Temp Chiller rotors are commonly classified into angular rotors and horizontal rotors:

What is an angular rotor:

The angular rotor is the abbreviation of the fixed-angle rotor. The Angle θ between the centrifuge tube filled with the solution and the rotor shaft is formed during the manufacturing of the rotor and cannot be changed. The Angle between the centrifuge tube and the rotor shaft is generally between 14° and 45°. During the centrifugation process, the position of the centrifuge tube remains unchanged, and the sample undergoes redirection. The smaller the Angle between the centrifuge tube and the rotating shaft, the greater the degree of redirection, and the higher the efficiency of centrifugation.

2. What is a horizontal rotor:

The horizontal rotor, also known as the disengaged rotor, has centrifuge tubes placed in hanging cups. When the hanging cups are at rest, they are in a vertical and parallel state to the rotor shaft. When in use, the hanging cups must be symmetrically hung on the rotor. When rotating, the hanging cup is flung from the vertical position to the horizontal position due to the centrifugal force, so it is also called the external swing rotor and the balancing basket rotor, etc.
