Continuous flow tube centrifugeIn the market, it can be said that there are a hundred schools of thought competing, but generally we habitually distinguish based on size, speed, temperature, rotor, volume, and whether it is a desktop or handheld device. Of course, with the increasing number of product styles, there are also differences in centrifuge grade.
Traditional functions are not very complete, especially in terms of speed and capacity, which are not precise. For example, a normal speed is 5000 revolutions per minute, but in practice, the speed cannot reach 5000 revolutions per minute. This centrifuge is only suitable for ordinary centrifugation operations, such as separating serum and concentrating urine. Fine centrifuges have multiple functions, precise speed and capacity, and are suitable for experiments that require high centrifuge requirements, such as PCR experiments and blood component separation (mostly used in blood stations).
The common operation now requires the use of relative centrifugal force to set the operating conditions. Relative centrifugal force can more accurately describe the centrifugal effect with respect to speed. In daily use, centrifugal conditions should also be set based on the relative centrifugal force required for centrifugation. Some can set the self conversion connection between speed and relative centrifugal force based on the type of rotor used; For centrifuges that can only be set to a certain speed, the relative centrifugal force (RCF) calculation formula can be used to calculate it, converting the relative centrifugal force into the corresponding speed. Finally, the centrifuge must be calibrated by calibrating the speed.
The statement that details determine victory or defeat still has a certain truth. If many details are not paid attention to, it may lead to equipment problems, and even severe cases may result in equipment damage. That applicationContinuous flow tube centrifugeWhat details should we pay attention to? Let's discuss with the editor below.
1、 Preprocessing of liquid data to reduce processing volume
After pre-treatment, liquid materials should be sent to a continuous flow tube centrifuge as much as possible to remove most of the sediment and reduce the solid content. Mixing materials can increase fluidity. This can effectively improve the centrifugal separation effect and reduce the separation time.
2、 Control the feeding pressure and feeding speed
According to the characteristics of the materials and process conditions, choose high fuel tank feeding or pump feeding. When the nozzle diameter is fixed, the higher the intake pressure, the higher the output. Based on the characteristics of material control of feed flow rate, under the same separation factors, the smaller the flow rate, the smaller the output, and the better the separation effect of material liquid. In order to maintain the same separation effect, the feed volume should be larger at the beginning of the separation operation and smaller later on.
3、 Never give up halfway, reduce the number of shutdowns
In the separate operation process, in addition to the significant impact of slag accumulation inside the drum, the separation effect of slag is obstructed. Usually, the tube centrifuge does not stop halfway, and minimizing the number of halfway stops as much as possible will affect the separation effect.
