Abstract
The utility model relates to a device for absorbing energy during the MCA test process of a centrifugal machine. During the MCA test process of the centrifugal machine, the housing of the centrifugal machine is required to restrain scraps produced during breakage, the scraps produced during breakage are within 300 mm; and during the MCA test process of a high-capacity centrifugal machine, and energy up to 300 kilojoule is released instantly, so that a device for absorbing the releasing energy is required. The utility model aims to develop a device used for absorbing energy released during the MCA test process of the high-capacity centrifugal machine; the device comprises a housing, an outer protective sleeve, a pallet board and a stop block; the stop block is fixed on a middle baffle plate of the housing through a bolt; the pallet board is mounted on the middle baffle plate in the housing, and rotates in a circular ring enclosed by four stop blocks; and the external protective sleeve is mounted on the pallet board, and can rotate around a ring-shaped ring on the pallet board. The utility model has the advantages of reasonable design, simple structure, low cost, and high safety performance.
Description
Technical field:
The utility model belongs to centrifuge security technique field, is specifically related to the device that will release energy in a kind of big capacity centrifuge MCA test process and absorb.
Background technology:
According to GB4793.7 (idt IEC 61010-2-020) " security laboratory of measurement, control and laboratory electrical installation with the specific (special) requirements regulation of centrifuge ": in the centrifuge MCA test process, require the centrifuge shell can suppress the fragment of breakage generation.Centrifuge and damaged fragment should be in the 300mm scopes of safe space.In the big capacity centrifuge MCA test process, the energy of release is up to 330 kilojoules.So big energy needs the device that will release energy and absorb in a kind of big capacity centrifuge MCA test process in abrupt release.Originally big capacity centrifuge outer jointing jacket and casing Bolt Connection are not that the outer jointing jacket of rotation cuts off attachment bolt and clashes into casing in the MCA test process, and the related casing of Xuan Zhuan outer jointing jacket rotates together exactly.Centrifuge and damaged fragment exceed the safe space, cause the MCA test crash.
The utility model content:
The purpose of this utility model is to overcome above-mentioned weak point, and the apparatus and method that will release energy in a kind of big capacity centrifuge MCA test process and absorb are provided.
The utility model is achieved in that it comprises casing, outer jointing jacket, pallet, block, and block is by being bolted on the casing median septum.Pallet is placed on the casing median septum, and pallet can rotate in the annulus that four link stoppers surround.Outer jointing jacket is placed on the pallet, and outer jointing jacket can rotate by the annular ring on pallet.
The utility model operation principle and technique effect:
Its principle of the utility model: MCA is the maximum credible accident (MCA) test; the rotor fork arm lost efficacy during centrifuge MCA test; the rotary head of rotation and institute's bringing onto load clash into outer jointing jacket at a high speed, and radial component makes outer jointing jacket that radially deformation take place, and tangential component makes outer jointing jacket rotate around the axle center.When outer jointing jacket radially deformation surpass certain value.Outer jointing jacket locking pallet drives pallet rotation together in casing.The energy overwhelming majority that produces during the MCA test is absorbed by the deformation of outer jointing jacket and rotation.And do not cause the casing breakage.Can not cause the casing rotation yet.Centrifuge and damaged fragment do not exceed the safe space.The MCA test passes, and has effectively confirmed the centrifuge security.
Description of drawings:
Accompanying drawing 1: be the utility model overall structure schematic diagram
Figure grade: 1 casing, 2 outer jointing jackets, 3 pallets, 4 blocks, 5 rotary heads
The specific embodiment:
Endergonic device in the centrifuge MCA test process of the present utility model; it includes casing (1); outer jointing jacket (2); pallet (3); block (4); rotary head (5); block (4) is set to four by the four directions; by being bolted on casing (1) median septum; pallet (3) peace is arranged on casing (1) median septum; pallet (3) can rotate in the annulus that four blocks (4) surround; outer jointing jacket (2) is placed on the pallet (3); outer jointing jacket (2) can rotate around the annular ring on the pallet (3); rotary head (5) and institute's bringing onto load bump outer jointing jacket (2) when rotation at a high speed; warp-wise component makes outer jointing jacket (2) that radially deformation take place, and make outer jointing jacket (2) rotate around the axle center tangential the branch.When outer jointing jacket (2) radially deformation surpass certain value, outer jointing jacket (2) locking pallet (3).Drive rotation together in the pallet (3), its energy overwhelming majority is absorbed by the distortion of outer jointing jacket (2) and rotation, can not cause casing (1) rotation; cause casing (1) breakage, guaranteed centrifuge safety effectively, it is reasonable in design; simple in structure, good practical effect.
Claims (1)
