Ho tšoaea li-washer tse sephara

"Na li-washer tse bataletseng li hloka ho tšoauoa?" “Che?”

“Na baa e hloka?”……

Kajeno re buisana ka taba ena le uena, mohlomong batho ba bangata ba indasteri ba tla nahana“Xiaowan ah, ha u setsebi ……”.

Joalo ka ha bohle re tseba, li-washers tse bataletseng e le khokahano ea fasteners ea ho lekana ha bohlokoa, haholo-holo li phetha karolo ea ho eketsa sebaka sa ho ikopanya, ho qhala karolo ea khatello ea ho ikopanya. Bongata bo boholo ba li-washer tse bataletseng tse sebelisoang kopanong ea indasteri ha li tsejoe joalo ka tse setšoantšong se ka tlase.

Joale ke maemo afe moo li-washer tse bataletseng li tla tšoauoa?

(1) Setsi sa tlhahiso ho qoba ho kopanya lisebelisoa

Flat washers bakeng sa tshebetso ya tlhahiso ea moqotetsane hlobolisa stamping ho bōptjoa, tlhahiso ea semela sebakeng se bataletseng washer holim'a tšoaea ke e le ho qoba tlhahiso ea lintlha tse tšoanang tsa thepa e fapaneng washers flat, ka tlhahiso kapa transit tshebetso ya lintho tse bonahalang pherekano le mokhoa oa ho laola tshebetso. Ka mohlala, the“304”setšoantšong se latelang, ke hore, molemong oa washer e bataletseng ke lisebelisoa tsa A2. Haeba moetsi a hlahisa washer e bataletseng ea lintlha tse tšoanang ka thepa ea 316 ka nako e le 'ngoe, joale mochini o hlatsoang o ka tšoauoa ka“316”or “A4”.

Pontšo ena ea boitsebiso boitsebiso bo tloaelehile ka tšepe e se nang tšepe flat washers, lebaka ke hore ka mor'a hore tlhahiso ea lihlahisoa tsa tšepe e sa hloekang ka kakaretso etsoa feela ka mor'a ho hloekisa le passivation, ho tloha ponahalo ea bosoeu bo khanyang, a ke ke a intuitively khethollang thepa ea eona.

Thepa e hlakile ka holim'a li-washer tse sephara tsa tšepe tse se nang tšepe li ka qoba ka katleho tlhahiso kapa mokhoa oa kopano oa thepa e tsoakiloeng.

(2) litokisetso tse tloaelehileng

Maemo a mang a sehlahisoa a totobatsa litlhoko tsa li-washer tse sephara tse tšoailoeng, mohlala, maemo“EN”, “EN”, “EN”, “EN”, “EN”le“EN”.

Ka mohlala, tekanyetso“TS EN 14399-5 (GB / T 32076.5) manonyeletso a bolt a matla a holimo Karolo ea 5: Li-washer tse bataletseng”ka har'a li-washer tse bataletseng tse tingoeng le tse halefileng li lokela ho tšoauoa ka sekoti, joalo ka ha ho bonts'itsoe ka tlase:

Ka mohlala, tekanyetso“Lisebelisoa tsa tšepe tse thata tsa ASTM F436”e totobatsa hore li-washer tse bataletseng tse ipapisitseng le maemo ana li lokela ho tšoauoa ka“F436”letšoao, joalokaha ho bontšitsoe ka tlase:

Li-washer tse bataletseng tse tšoailoeng kapa tse sa tšoauoang ka maemo li ka ipapisa le tsona?

Ha u sheba ka litekanyetso tsa hona joale tsa sehlahisoa, litekanyetso tsa li-washers tse bataletseng hore na ho bapala ho tšoaea ha ho hlalosoe ka ho hlaka.

Tekanyetso ea ISO 898-3: 2018 (lintho tsa mochini oa li-fasteners - li-washer tse bataletseng) Tekanyetso ke ts'ebetsong ea litlhoko tsa ts'ebetso bakeng sa carbon steel, alloy steel material flat washers ka 2018, eo khaolo ea 9.2 bakeng sa letšoao la ho hlatsoa sephara e entseng litokisetso tse hlakileng.

Letšoao la washer e bataletseng e ka ba ka boikhethelo ba moetsi kapa ka tumellano lipakeng tsa phepelo le tlhoko.

Li-washer tse bataletseng li ke ke tsa tšoauoa ka litlhaku tse phahamisitsoeng. Ho tšoaea ha concave hangata ha ho khothaletsoe hobane ho ka fetola kamano ea matla a torque-clamping ea lenonyeletso la bolt-nut kapa ho baka khatello ea maikutlo e ka bakang ho phatloha ha washer.

Lintlha tse peli tse ka holimo li bontša hore ho tšoaea li-washer tse bataletseng ha ho tlamehe, 'me ho ho mofani oa thepa ho etsa qeto kapa ho buisana ka hore na hoa hlokahala ho tšoaea pele ho odara. Ha ho khothalletsoe ho tšoaea holim'a li-washer tse bataletseng tse nang le litlhaku tse khabisitsoeng kapa tse concave.

Austenitic stainless steel flat washer surface concave marking e tla fetola bolt - nut connecting vice torque - clamping force relationship has to be proved, ho na le bonnete ba hore, ka lebaka la boima bo tlase ba austenitic stainless steel, ho tšoaea ha concave ho ke ke ha lebisa khatellong ea maikutlo ho washer, ho ke ke ha baka ho phatloha ha washer.
