Analysis of medical centrifuge fault

The relevant medical centrifuge other information please visit http://www.shlxj.com.cn/ for more details.
Medical centrifuge to understand some of the total due to the improper use of instruments and failed to regular maintenance and other reasons, the centrifuge accidents occasionally attack. In order to use of advanced instrument rate and extend the use life of the instrument, to ensure safe operation, prevent accidents, technician summarizes the reasons about the attack laboratory centrifuge accident analysis, and clarify the main points of maintenance laboratory centrifuge.
Medical centrifuge is explained by the traditional theory, medical centrifuge rotor imbalance problem is excessive cause, and medical centrifuge weighing error, sample centrifugal during centrifugation of sample liquid overflow and corrosion are the main elements of the rotor rotor imbalance.
Medical centrifuge to summarize the reason mainly has the following several:
Medical centrifuge for 1 medical centrifuge tube balance, because balance long-term use and not corrected, centrifugal tube is not balanced symmetrically placed beyond the 0.1 ~ 1G.
2 medical centrifuge tubes in loading the sample, because the sample liquid beam fill or centrifugal cap is not screwed tight seal, high vacuum centrifugal cavity formed during centrifugation centrifugal pipe pumping flat, break and sample liquid from overflowing, forming the rotor unbalance attack bent shaft or shaft broken accident.
3 as the proportion is not equal to trim the liquid proportion, rotor dynamic balance disorders and accident.
4 using the degree of rotor, not careful will serial number and degree of the rotor body bucket sequence number of the installed wrong, the influence of rotor dynamic balance.
5 aluminum alloy centrifugal tube cap and the stainless steel centrifugal pipe cap (two different mix proportion) and accident.
6 centrifugal inside the cap rubber sealing ring and the rotor cover rubber sealing ring, improper use and improper disinfection, medical centrifuge suggestions such as long-term use of internal faults and solid high-temperature sterilization using R boring box of baking) dispose and aging cracking, loss of sealing effect, so that the sample overflow when running at high speed, so that the rotor running in an unbalanced state under the.
7 of the centrifugal tube to various data, using the former fails to understand the centrifugal tube manufacturers request application scope and methods of disinfection, medical centrifuge suggest using chemical solvents and disinfectant inappropriate disposal, forms a centrifugal tube in the operation of the swelling, rupture and accident.
About 8 medical centrifuge to the work of carelessness, rotor cover not tighten or the rotor cover and rotor handle swap, forming screw does not match, when the starting operation, rotor cover throws and had severe shaft broken accident.
