It is identical with ISO6392-2:1996 Earth-moving machinery Lubrication fittings Part2:Grease-gun nozzles published by the International Organization for Standardization (ISO). ISO

8、 6392-2 was prepared by Subcommittee3, Operation and maintenance, of ISO Technical Committee127, Earth-moving machinery, with the active participation and approval of the UK. This text represents a revision, in Parts, ofISO6392:1980. The other Part, ISO 6392-1 Earth-moving machinery Lubrication fitt

This will be indicated in the amendment table on the inside front cover.BS6913-14:1997 ii BSI 09-1999 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bo

13、dies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizatio

14、ns, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulat

15、ed to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO6392-2 was prepared by Technical Committee ISO/TC127, Earth-moving machinery, SubcommitteeSC3, Operation and maintenance. This

16、first edition of ISO6392-2 together with ISO6392-1 cancels and replaces ISO6392:1980, which has been technically revised. ISO 6392 consists of the following parts, under the general title Earth-moving machinery Lubrication fittings: Part 1: Nipple type; Part 2: Grease-gun nozzles. Annex A andAnnex B

17、 of this part of ISO6392 are for information only. Descriptors: Earth-moving equipment, lubrication, lubrication systems, fittings, grease guns, nozzles, specifications, dimensions.BS6913-14:1997 BSI 09-1999 1 1 Scope This part of ISO6392 specifies grease-gun nozzles to be used for the injection of

18、grease into the lubrication points of earth-moving machinery by means of the grease fitting specified in part1 of this InternationalStandard. The grease-gun nozzles covered by this part of ISO6392 are used on the types of earth-moving machinery defined inISO6165. 2 Normative reference The following

19、standard contains provisions which, through reference in this text, constitute provisions of this part of ISO6392. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part ofISO6392 are encouraged to investigate

20、the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid InternationalStandards. ISO 6165:, Earth-moving machinery Basic types Vocabulary 1) . 3 Nozzle type and mounting position 3.1 Nozzle type Nozzle types are

21、 divided into two types: the rubber nozzle-centre type (seeFigure 2) and the steel nozzle-centre type (seeFigure 3). The rubber nozzle-centre type is recommended for the grease-gun nozzles to be used on earth-moving machinery. For the grease injection into the grease fitting, the rubber nozzle-centr

22、e type is superior in sealability and grease leakage is less compared to the steel nozzle-centre type. 3.2 Mounting position Figure 1 shows an example of the mounting position of the grease-gun nozzle. The specific type of grease gun is not prescribed. 1) To be published. (Revision of ISO6165:1987)

23、Figure 1 Figure 2 Rubber nozzle-centre typeBS6913-14:1997 2 BSI 09-1999 4 Structure The structure of the grease-gun nozzle shall be able to withstand a working pressure of20MPa and a minimum destructive pressure of80MPa without leakage. When the grease-gun is used in a track adjuster, the grease inj

24、ection pressure can exceed50MPa; the life of the nozzle (number of leak free applications) may decrease if the grease-gun is removed under the residual pressure. It is therefore recommended to use the grease-gun nozzle with a relief valve. 5 Dimensions, materials and finish 5.1 Dimensions The dimens

25、ions of grease-gun nozzles shall be as shown inFigure 2 andFigure 3 andTable 1. Table 1 5.2 Materials 5.2.1 Rubber nozzle-centre type The nail and the spacer (seeFigure 2) shall be manufactured from steel with a Rockwell hardness of at least45HRC. The nozzle centre shall be manufactured from rubber

26、with hardness75IRHD to95IRHD. 5.2.2 Steel nozzle-centre type The nail and the nozzle centre (seeFigure 3) shall be manufactured from steel with a Rockwell hardness of at least45HRC. 5.3 Finish Nozzle bodies and covers (seeFigure 2 andFigure 3) shall be electroplated with zinc and chromate treatment

27、in accordance with ISO2081. 6 Grease injection angle There shall be no leakage of grease when the nozzle is coupled to the grease-nipple and inclined up to the injection angle of10max.
