The Medical centrifuge uses an advanced rotary dynamic design
Medical centrifuge generally work at very high speeds. When the centrifugal force experienced by the rotor exceeds the tensile strength of the rotor material or there is an internal defect in the rotor material, the rotor can explode, destroy the equipment and endanger the safety of the operator. Therefore, each rotor has the highest operating speed allowed. The automatic identification of the rotor and the overspeed protection function by scanning the barcode of the rotor surface to identify the rotor, eliminating the incorrect entry of the operator or centrifuges out of control cause excessive rotor speed and information of the rotor. rotor automatically enters the computer and storage. To control the life of the rotor.
The integral safety system of the medical centrifuge includes electronic lock, room door made of steel structure and three-layer safety protection box, automatic rotor identification and overspeed protection, rotor dynamic imbalance detector and temperature protection Ultra high centrifugal chamber. This centrifuge has a self-diagnostic system that always monitors the various functions of the centrifuge and directly shows the location of the fault, sends an alarm signal, so that maintenance is more convenient and the transmission part is lubricated permanently with the bearings and forced closed self-lubrication. When it is on, it will not damage the main unit. After the power is restored, it will start automatically.
The long service life of medical centrifuges has a direct relationship with their materials. Therefore, in the process of buying centrifuges, we must have a certain understanding of the materials. The strength of the materials used in medical centrifuges is reflected in the speed of the centrifuge. In. These factors directly affect the volumetric flow and mass flow, the corrosion of medical centrifuges is also related to the structure of their internal parts. For example, drums and screw conveyors are usually melted and welded in stainless steel, or made of high-strength stainless steel and titanium steel, and can also be made of fiberglass. At present, domestic and foreign equipment, the main components are made of stainless steel, in particular, the drum and the spiral part use stainless steel, only a few foreign manufacturers can use the appropriate material for different waste objects and requirements of media. For the elimination of wastewater and non-corrosive sites, high-strength carbon steel is used for protection against corrosion. As much as possible, consider the housing to save data and reduce costs, such as the use of fiberglass casing. In order to effectively maintain the drum, the slag discharge orifice is provided with a wear sleeve, and the ribs or grooves of the inner surface are provided inside and outside the drum.
In recent years, to select the best solution, the researchers used the flow field separation method, the finite element simulation method, the large gradient density step method and the antimodal analysis method to study the performance labor and the key parts of medical centrifuges. The centrifuge with excellent performance provides a theoretical basis. To improve the purity of the products and meet the requirements of energy and environmental protection, high parameters have become the development characteristics of centrifuges.
The centrifugal decanter with large separation factor adopts an advanced rotary dynamic design. The main bearing adopts an elastic installation that can prolong the service life and reduce noise and vibration. To improve the performance, strength, rigidity, wear resistance and corrosion resistance of centrifuges, a new batch of materials is used in centrifuges, such as engineering plastics, hard alloys and wear-resistant stainless steel materials. and corrosion. With the development of automatic detection and control technology, many advanced automatic control methods have been introduced. All parameters, such as temperature, flow rate, speed, amplitude and noise, are controlled in the operation of medical centrifuges and are collected by sensors. The information is entered into the computer. After being processed by the system, changes in various parameters can be known in time to take the appropriate measures. With increasingly fierce market competition, the manufacturing industry faces great challenges to improve customer value. Since the 1990s, mass customization has gradually emerged in the manufacturing industry, producing products and providing services that approximate the efficiency of mass production to meet the individual needs of customers.
Centrifugal medical centrifuge technology is a specialized technique for separating, concentrating and analyzing substances using centrifugal force, based on the difference in the sedimentation coefficient, the diffusion coefficient and the density of flotation of a substance. The centrifugation technique is closely related to the experiments of phage-infecting cells, experimental evidence of semi-retained DNA replication, pectinase preparation and chicken blood cell fluid, separation of hemoglobin solution and various organelles and cell fusions.
