20、oduction This International Standard gives dimensional details of circular and rectangular flanges of fans in addition to specifying the fan size designation. For circular flanges, the values specified in ISO 6580 have been retained for light-duty fans, in parallel with those values given in Tables

21、3 and 4 for medium- and heavy-duty fans. While it does not constrain the manufacturers choice of flange details, this International Standard facilitates interchangeability, thereby helping to reduce technical barriers to trade. Throughout this International Standard, the principal dimensions are bas

22、ed on the rounded values of preferred numbers given in ISO 497. DIN EN ISO 13351:2011-11 1 Scope This International Standard specifies the dimensions of the circular and rectangular flanges of general-purpose fans, as well as the fan size designations. It is not applicable to cross-flow fans or to f

23、an appliances used for individual household or similar applications. For circular flanges, it provides for three different flange series: one for light-duty casing thicknesses, another for medium-duty fans and the third for heavy-duty fans as used on sea-going vessels or in heavy industry. In order

24、not to restrict fan design unduly, only the pitch diameter, hole numbers and hole diameters are specified. Flange thickness, as well as internal and external flange diameters, may be chosen freely within the limits of good engineering practice. 2 Normative references The following referenced documen

31、ly, D = DRFigure 3 Impeller Mixed-flow fan 4 Requirements 4.1 General This International Standard adopts the Renard R 20 series according to ISO 497 as the nominal dimensions for impeller tip diameters, the inside diameters of circular flanges and the inside lengths of the sides of rectangular flang

32、es. It takes into account the maximum casing thicknesses likely to be used for general-purpose fans, as well as typical manufacturing tolerances representative of engineering “good practice”. The smallest practical pitch circle diameter can be related to the inside diameter of the casing, the casing

33、 thickness, the size of the weld fillet or bend radius at the junction of the flange and the casing, and the normal washer diameter. Light-duty circular flanges might not be suitable for the use of open-ended spanners in all cases. 7EN ISO 13351:2009 (E) DIN EN ISO 13351:2011-11 This International S

34、tandard accepts that the number and diameter of bolts or screws cannot be established on a theoretical basis. Practical experience of satisfactory service, optimum cost of installation and manufacture, as well as dimensional tolerances of production are the most important considerations. The dimensi

35、ons of circular and rectangular flanges are given in sizes corresponding to nominal diameters from 100 mm to 2 000 mm. In the smaller sizes (below about 200 mm) flange details may be determined by the customers specification. However, where this is not the case, then the specifications of this Inter

36、national Standard are to be applied. 4.2 Circular flanges The number of flange holes is divisible by four to permit the orientation of cylindrical cased fans at positions of 90. The holes are disposed equally on each side of the centrelines of the fan. This permits a flange to be divided in half if

37、a split casing is required. It also allows better access to the fixings on the remote side of a fan in a confined installation. When an intermediate fan size is required, the R 40 series in accordance with ISO 3 shall be used to obtain the nominal inside diameter. The flange details shall be interpr

38、eted from the next larger R 20 size. In exceptional circumstances, when even smaller increments of fan size are required, it is recommended that the R 80 series be used. See Figure 4.
