Sumo yeFittings: kuona saizi yeshinda uye kurira

Kushanda kweindasitiri fluid system kunoenderana nekubatana kwechimwe nechimwe chikamu chinoendesa yako process fluid kune kwainoenda. Kuchengetedzeka uye kubereka kwechirimwa chako kunoenderana nekuvuza kwemahara kubatanidza pakati pezvikamu. Kuti uone kufanirwa kweiyo fluid system yako, tanga wanzwisisa uye kuona saizi yeshinda uye kukwirira.

Thread uye kugumisa Foundation

Kunyange nyanzvi dzine ruzivo dzimwe nguva dzinowana zvakaoma kuziva shinda. Izvo zvakakosha kuti unzwisise zvakajairika tambo uye kumisa mazwi uye zviyero kubatsira kurongedza chaiyo shinda.

Thread type: shinda yekunze neshinda yemukati zvinoreva nzvimbo yeshinda pajoini. Rwonzi rwekunze rwuri kubuda kunze kwejoini, ukuwo rwonzi rwemukati rwuri mukati mejoini. Rwonzi rwekunze rwunopinzwa mushinda yemukati.

Pitch: pitch is the distance between threads. Kuzivikanwa kwepitch kunoenderana neshinda chaiyo, seNPT, ISO, BSPT, etc. Pitch inogona kutaridzwa neshinda painch uye mm.

Addendum uye dedendum: kune nhongonya uye mipata mushinda, iyo inonzi addendum uye dedendum zvakateerana. Nzvimbo yakati sandara pakati pemuromo nemudzi inonzi flank.

Ziva mhando ye thread

Nhanho yekutanga yekuziva saizi yeshinda uye kukwirira kuve nemidziyo yakakodzera, kusanganisira vernier caliper, pitch gauge uye pitch identification gwara. Vashandise kuona kuti shinda yacho yakadhindwa here kana kuti yakatwasuka. tapered-shinda-vs-yakatwasuka-shinda-dhayagiramu

Tambo yakatwasuka (inonziwo tambo inofanana kana tambo yemagetsi) haishandiswe kuisa chisimbiso, asi inoshandiswa kugadzirisa nati pamutumbi wekubatanidza wecasing. Vanofanira kuvimba nezvimwe zvinhu kuti vagadzire zvisimbiso zvinovuza, sengegaskets, O-mhete, kana simbi kune simbi kusangana.

Tapered threads (inozivikanwawo se dynamic threads) inogona kuvharwa kana mazino mativi ekunze nemukati meshinda adhonzwa pamwechete. Izvo zvinodikanwa kushandisa tambo sealant kana tambo tepi kuzadza gap pakati pezino reti uye mudzi wezino kudzivirira kubuda kweiyo system fluid pajoinhi.

Taper shinda iri pakona kumutsara wepakati, ukuwo shinda inofambirana ichienderana nepakati. Shandisa vernier caliper kuyera chidimbu kuti upe dhayamita yeshinda yekunze kana shinda yemukati pane yekutanga, yechina uye yekupedzisira yakazara shinda. Kana iyo dhayamita ichiwedzera pamagumo emurume kana kuderera pamagumo echikadzi, shinda inoputika. Kana madhayamita ese akafanana, shinda yakatwasuka.

Kuyera dhayamita yeshinda

Mushure mekunge maona kuti muri kushandisa shinda dzakatwasanuka here kana kuti dzakatepwa, danho rinotevera nderokuona dhayamita reshinda. Zvekare, shandisa vernier caliper kuyera zita rekunze shinda kana yemukati dhayamita kubva pamusoro pezino kusvika kumusoro kwezino. Kune shinda dzakatwasuka, pima chero shinda yakazara. Kune shinda dzakatetepa, pima shinda yechina kana yechishanu yakazara.

Huyero hwedhayamita hwakawanikwa hunogona kunge hwakasiyana nehukuru hwezita hweshinda dzakapihwa dzakanyorwa. Shanduko iyi imhaka yekusarudzika kwemaindasitiri kana kushivirira kwekugadzira. Shandisa chinongedzo chemugadziri weshinda yekubatanidza kuona kuti dhayamita iri pedyo nesaizi chaiyo sezvinobvira. thread-pitch-gauge-measurement-diagram

Sarudza chirevo

Danho rinotevera nderokuziva kuti nhanho yei. Tarisa shinda pachimiro chega chega nejeji yepitch (inozivikanwawo semuzinga) kusvika mucheno wakakwana wawanikwa. Mamwe maumbirwo echirungu nemetric thread akafanana zvakanyanya, saka zvinogona kutora nguva.

Gadzira pitch standard

Nhanho yekupedzisira ndeyekumisa mwero wepitch. Mushure mebonde, mhando, dhayamita yezita uye nhanho yeshinda yatemwa, tambo yekuzivisa chiyero inogona kuzivikanwa neshinda yekuzivisa gwara.
