DIN EN 14986-2017工作在潛在易爆環(huán)境中電扇的設計;德文版本EN 14986-2017

1.1 This European Standard specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE Operation conditions for the different categories of fans used in this European Standard are defined in Clause 4. 1.2 This European Standard does not apply to group I fans (fans for mining), cooling fans or impellers on rotating electrical machines, cooling fans or impellers on internal combustion engines. NOTE 1 Requirements for group I fans are given in EN 1710. NOTE 2 The requirements for electrical parts are covered by references to electrical equipment standards. 1.3 This European Standard specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres may exist inside (the conveyed fluid), outside, or inside and outside of the fan. 1.4 This European Standard is applicable to fans working in the range of ambient atmospheres having absolute pressures ranging from 0,8 bar to 1,1 bar, temperatures ranging from -20 °C to +60 °C, maximum volume fraction of 21 % oxygen content and an aerodynamic energy increase of less than 25 kJ/kg.

DIN EN ISO 14691-2009石油、石化和天然氣工業(yè).機械動力傳輸用軟管.通用設備

This International Standard specifies the requirements for couplings for the transmission of power between therotating shafts of two machines for general-purpose applications in the petroleum, petrochemical and naturalgas industries. Such applications typically require couplings to transmit power at speeds not exceeding4 000 r/min, between machines in which the first lateral critical speed is above the running speed range(stiff-shaft machines). It can, by agreement, be used for applications outside these limits.NOTE 1 Recommendations are included in the Introduction as to when the use of ISO 10441 should be considered.This International Standard is applicable to couplings designed to accommodate parallel (or lateral) offset,angular misalignment and axial displacement of the shafts without imposing excessive mechanical loading onthe coupled machines. Couplings covered by this International Standard include gear (and other mechanicalcontact types), metallic flexible-element and various elastomeric types. Such couplings can be of all metalconstruction or can include components of non-metallic materials, such as composites.This International Standard covers design, materials of construction, inspection and testing of couplings andmethods of attachment of the coupling to the shafts (including tapered sleeve and other proprietary devices).This International Standard does not apply to special types of couplings, such as clutch, hydraulic, eddy-current, rigid and radial-spline types.This International Standard does not define criteria for the selection of coupling types for specific applications.NOTE 2 In many cases, couplings covered by this Intemational Standard are manufacturers' catalogue items.
