How to correctly analyze the vibration noise of desktop centrifuge

There are occasional vibration noises in the use of desktop centrifuges. To solve this problem, first analyze the causes of vibration noise. Today's laboratory instruments - Hunan Gilson Xiaobian for your simple analysis of several:

(1) The upper part of the rotating shaft is fixed to the turntable screw or the vibration-retaining spring fixing screw on the machine base, and the fasteners are loose. Just re-tighten it once.

(2) The motor shaft is bent or the bearing is worn. If the motor shaft is bent, it can be solved by repairing the correction. If it is serious, it should be replaced. If the gap is increased after the bearing wears, add a gasket to the shaft to solve it. If it is serious, it should be replaced.

(3) The three spring-loaded springs on the machine base become smaller or broken, which makes the turntable shake more when it rotates. Just replace the shock absorbing spring.

(4) The cover is deformed or incorrectly positioned. Just fix, adjust and correct the cover. And the cover can be fixed and fixed.

(5) There is a foreign matter such as broken glass in the test tube sleeve, which makes the load unbalanced. Before use, check whether there are other foreign objects in each test tube sleeve. If it is, it must be removed before use.

(6) The test tube sleeve does not match the machine. The test tube sleeve is precisely matched by the manufacturer to the machine. Different types of centrifuge tube sleeves cannot be replaced at will. Otherwise, vibration and noise will be generated when the centrifuge is working.
