1 Centrifuge touch keyboard out of control <br> Fault phenomenon: Press any button after power on, no response, the instrument enters the crash state.
Fault Analysis: There are two reasons for the loss of the touch keyboard: (1) The touch keyboard is not powered. Touch the keyboard sticky key. Nothing happens when you press the power button. It may be that a stuck keyboard prevents the computer from correctly recognizing the keyboard status and causing a crash.
Troubleshooting method: After checking, the power of the touch keyboard is normal. Turn off the power and remove the screws that touch the keyboard. Gently pry the touch keyboard away from the mezzanine. After the non-keyboard button part of the keyboard interlayer of the machine is pasted with double-sided tape, the touch keyboard can be restored. It should be noted that the double-sided tape cannot be placed too high.
2 Motor overheating <br> Fault phenomenon: Motor overheating usually has the following environments:
The starting time of the centrifuge is ≤60s. If the starting time is long, it is probably the wear of the throwing block. The weight is too light, the appearance of the friction plate is oily and the motor has quality problems. Therefore, it is necessary to change the loaded throwing block or check the motor.
The starting current is large, the starting current of the centrifuge is about 2.5 times of the rated current, and the starting current of the load is about 3 times of the rated current. If the current is higher than this value, it is probably the quality problem of the motor, the power line is accurate, the motor shaft Whether it is bent, whether the clutch has a sign of jamming, and whether the clutch throwing block is overweight.
3 vibration
The vibration of the air running is large: the vibration of the centrifuge is tense because the unbalanced quality of the drum and the gap between the drum supports are too large, and the bolts and the nuts of the joint parts are loose. If the use time is long and the corrosion is tense, then the possibility of cracking the drum weld or other parts should be considered. Accidental drums accumulate too much material, causing the drum to be heavy and causing vibration. Others such as spindle bending and bearings Destruction and the like also cause vibration. The vibration of the load operation is large: the vibration of the load operation is in addition to the above reasons. The tension is caused by the uneven distribution of materials, which causes the vibration to be caused by the uneven distribution of materials. The method of mediation of the feeding method and the uniform fabric can be handled. Secondly, it is probably because the drum is used for a long time or suffers. bump caused by the deformation, the thickness of the cake layer is formed in the drum will not be able to process using the uniform, so it appears dull vibration. 
Backman Beckman High Speed ​​Centrifuge Maintenance Frequently Asked Questions
During the high-speed rotation of the centrifuge, the movement caused by the centrifugal force causes the solid matter suspended in the liquid to form a sediment, that is, the mass or volume of the suspended body fluid moves to the direction of the largest radius of the rotor, and the mass or The smaller part is deposited near the radius of the rotor. Since the radius of the rotor and the quality of the sample are constant during operation, only the rotational speed can be changed by control, so we tend to use the rotational speed to describe a centrifuge, such as a high-speed centrifuge or an ultra-high-speed centrifuge.
