How Should The Centrifuge Choose The Rotor?

Jun 08, 2017

Before using the centrifuge to understand the components of the centrifuge and the use of the centrifuge, which is conducive to the life of the centrifuge, centrifuge drum is an important component of the centrifuge, and production safety requirements are closely related The In this Shanghai Lu Xiangyi company to remind the majority of users, not because of cheap to buy a poor centrifuge, the purchase of centrifuges must be in accordance with the requirements of the centrifuge drum to buy the thickness of the centrifuge and the parameters of the work.

Centrifuge safe use requirements:

1, the selection to be correct.

2, according to the provisions of the scope of the use of centrifuges, can not be used for general purpose centrifuges for flammable and explosive occasions and corrosive occasions.

3, according to the provisions of the operating procedures to run, not non-normal braking and overload operation, speeding operation.

4, should be promptly ruled out the failure, not to run with the failure of the centrifuge, the timely retirement of the failure of the centrifuge.

5, according to the requirements of the product manual installation, use, maintenance of centrifuges, not to modify the parts of the centrifuge, not to improve the speed of the centrifuge.

6, the development of centrifuge to develop, use and maintenance of the corresponding rules and regulations and strictly enforced to achieve the purpose of safe use.

How to choose the rotor in the procurement of centrifuges, from the following formula can be calculated:

When the capacity is determined, the most important parameter is not a speed but centrifugal force, the size of the centrifugal force directly determines the separation effect, different manufacturers of the same capacity of the rotor can achieve the same speed, but the centrifugal force is not necessarily the same, and some manufacturers In order to reduce the production cost, to overcome the noise, the rotor angle is made particularly small (small angle small centrifugal radius), so the same speed than the large angle rotor centrifugal force is small, it is not convenient to collect centrifugal

Attached: Centrifugal force calculation formula:

RCF = 11.2 × R × (r / min / 1000) 2

The above formula for the centrifugal force (RCF) formula R represents the radius of the rotor classification, r / min represents the speed.
