The consequences of an imbalanced centrifuge are very serious.

　　 Centrifuge Generally speaking, there are two main requirements. The first is speed—because the speed directly affects the effectiveness of centrifugation. The second is balance. To give a simple example, if your household washing machine isn't balanced when spinning, it’ll shake—and in severe cases, it might even shift position. Fortunately, the washing machine is only designed for clothes. But think about it from another angle: if a centrifuge becomes unbalanced, the consequences could be unimaginable.
　　The centrifuge’s inherent ability to withstand imbalance not only enhances its robustness but also simplifies user operation, as it eliminates the need for strict balance during rotor operation—indeed, visual balance alone is often sufficient. Typically, small centrifuges mount the entire motor on vibration-damping elastic supports, such as rubber pads; high-speed centrifuges often employ flexible shafts for vibration isolation. Since the wall thickness of the current drum design already meets strength requirements and features a substantial safety margin, from a cost-saving perspective, we have optimized the drum using the finite element method. While maintaining adequate strength and stiffness, this optimization gradually reduces the drum’s wall thickness and examines how changes in wall thickness parameters affect the stress SINT and radial displacement DZ. The purification accuracy of a centrifuge is limited by the rotor’s rotational speed, while the bearing’s load-carrying capacity represents a critical bottleneck when selecting high-performance drive equipment. Given the limited load-carrying capacity of conventional rolling bearings, it is hoped that... Centrifuge The rotor system can achieve higher rotational speeds, and replacing conventional rolling bearings with permanent-magnet bearings represents a promising research approach to addressing this issue. The main shaft system of a centrifuge rotor supported by permanent-magnet bearings is shown in Figure 1. The structure of the permanent-magnet bearing is designed according to existing literature and features bidirectional functions—radial support as well as thrust support. Based on current domestic and international research on magnetic materials, the stator and rotor materials for permanent-magnet bearings are selected from high-strength rare-earth neodymium-iron-boron (NeFeB) permanent-magnetic materials.
　　There’s a significant difference between domestically produced and imported centrifuges. For centrifuges with the same functionality, imported models typically cost about 6 to 10 times more than their domestic counterparts. This is mainly because imported centrifuges are more durable and offer more precise control over temperature and rotational speed. Among centrifuges of the same class, price differences between models aren’t substantial; the main distinctions lie in performance and configuration.
　　The main difference between centrifuges lies in their performance: refrigerated centrifuges are significantly more expensive than standard ones. Some centrifuges also come with heating functions, and the more sophisticated the control program, the higher the price. A major difference, however, is in terms of configuration—sometimes the cost of accessories can even exceed the price of the main unit itself. When making a purchase, it’s important to note that, in addition to the main unit, you’ll need to consider the rotor(s)—both in terms of quantity and type—as well as essential items such as centrifuge tubes, tube holders, specialized centrifuge bottles, or blood bags. Only when you add up the costs of all these components can you determine the total price of a complete centrifuge system.
　　The centrifuge equipment and torque are transmitted to a computer-controlled system, which displays the actual torque values in real time via data. When the torque rises beyond a certain threshold, it can be determined—through careful analysis of the centrifuge’s operational behavior—that the cause is water. This conclusion has been reached after years of exploration and refinement. Following the detection of water, due to media friction within the screw conveyor, the material will begin to flow into the thermoplastic powder. Therefore, if the torque remains normal, it indicates that the equipment itself has a weak point somewhere; identifying and addressing this issue promptly is crucial. After surgery, the torque typically returns to normal levels. The differential protection device includes a torque-shear locking mechanism: when a shear fracture occurs, the automatic cutoff switch immediately stops the motor, serving as our interlocking mechanism. Although the machine comes to a halt, due to inertia, the drum continues to rotate for approximately 8 minutes. Consequently, should a shear fracture occur, triggering the drum’s foot pedal or causing the feed rate to increase suddenly, the centrifuge can be immediately shut down by activating the feed inlet stop mechanism. Centrifuge The adjusted speed eliminates the protective device for enclosed inlet materials.
