Centrifuge speed for performance analysis of disc centrifuge

One of the important factors of centrifuge design, including centrifuge disc speed, is the design parameter! It directly affects the separation effect and separation speed. The rotating speed of disc centrifuge is between 10000 RPM / min and 30000 rpm Between RPM / min, the value of the rotating speed is based on the large speed measured under the condition of idling. The rotor directly affects the sample quality of the centrifuge with high speed. The target speed is the speed that needs to be achieved in the separation process. When we select the centrifuge, we need to select the high speed of the centrifuge higher than the target speed, so as to ensure the positive separation of materials by the centrifuge Regular operation!

However, we know that the speed of the centrifuge is sometimes very unstable, and there are many reasons for the failure. Only by solving the problem of centrifuge speed and increasing the speed of centrifuge can the production efficiency of centrifuge be improved! Cause analysis of unstable speed of centrifuge

Under reasonable conditions, we increase the speed ratio of the electric motor by setting the diameter of the driven wheel and increasing the diameter of the speed wheel. At the same time, the speed is relatively increased and the friction and resistance are reduced. The centrifugal device between the runner is started by the frequency converter! Our customers sometimes go into the misunderstanding, the purchased centrifuge clearly does not have such a high speed, conditions do not allow the machine to increase the speed, the centrifuge for refitting, often because of high speed, fault, accident.

The disc separator can complete two operations: liquid-solid separation (i.e. separation of bottom concentration suspension), called clarification operation; liquid-liquid separation (or liquid-liquid-solid) separation (i.e. separation of emulsion), which is called separation operation. A centrifugal separator with a stack of conical discs in the drum is used to separate the components of emulsion and low concentration suspension by centrifugal sedimentation. The disc separator can be operated under closed, high temperature, low temperature, pressure and vacuum conditions. It is used to extract cream and juice from milk, purify beer, animal and vegetable oil and transformer oil, concentrate yeast and extract serum from animal plasma.
