JB/T 8051-1996 (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 perforated drum, the method of applying the finite element method to calculate the stress distribution state of the centrifuge drum, and the cyclic load Determination and 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 non-perforated, and the drum can be lined and screened: the material of the drum must be a tough metal material, and the influence of the operating temperature on the material has been taken into consideration when selecting the material. 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 function of the load drum is less than 750J; c) Household dehydrators driven by electric motors; d ) The drum circumference angle is less than 300m/s; e) High-speed centrifuge specially used in the nuclear industry;
