JB/T 8051-2008 (English Version) PDF

Scope: This standard specifies the calculation of the hoop stress on the drum wall when the centrifuge drum rotates, the selection of various coefficients, the strength verification method of the drum, the principles of applying the finite element method to calculate the stress of the centrifuge drum, and the verification method of fatigue strength. . This standard applies to centrifuge drums with uniform wall thickness (the main shaft is arranged horizontally or vertically). The drum wall can be perforated or not, and the drum can be lined, screened or without lining and screen: the material of the drum must be a tough metal material, and the operating temperature and medium resistance have been taken into consideration when selecting the material. Material effects. This standard does not apply to centrifuge drums under the following conditions: a) The ratio of drum wall thickness to radius δ/r1>0.1; b) The kinetic energy of the loaded drum is less than 750J; c) Household dehydrators driven by electric motors; d ) The peripheral speed of the drum is greater than 300m/s; e) High-speed centrifuge specially used in the nuclear industry.
