The metal tubing is, the cable earthing arrangement of the explosion proof cable gland for the equipment cable

摘要

(57) Abstract Objective The cable of the three-tiered structure where the wave attaching metal tubing is and the equipment is doneTry to be able earth simply in the explosion proof cable glandru. Constitution Cable retreat hole of pressure-resistant explosion proof box 2The ji in the major diameter section of the cylindrical computer 26 which is packed, yunionnaThe inside diameter section of tsuto 42 the ji included to be possible, this unionIt concatenates to ring condition to the inside diameter section of nut 42, with O ring 62The earth clamp which consists of multiple metal make clamp pieces which are done56 is laid out. In computer 26 union nut 42 spiral shellfishWhen it adjusts, in the destal of internal gasket 38 inside computer 26, yuThe gasket gland 40 which is laid out inside nionnatsuto 42The destal to do pressure welding, with the reaction force of this pressure welding power, earth kuraClamp piece of npu 56, inside diameter section of union nut 42Being guided by the tapered aspect 50, in union nut 42To displace to heart direction, each clamp piece of earth clamp 56To bond in the peripheral face of metal tubing 14of a buru 14, metal tubing 1As for 4a, clamp piece of earth clamp 56, yunionnatsuto 42, via computer 26, pressure-resistant explosion proof box 2Earth in shingu.
