Kuyera nemazvovharuvhu yeshavishaviSaizi yakakosha kuti ive nechokwadi chekuti inokwana zvakanaka uye kudzivirira kubuda kwemvura. Nekuti mavharuvhu emashavishavi anoita basa rakakosha mumaindasitiri akasiyana-siyana. Kusanganisira mafuta negasi, makemikari uye masisitimu ekudzora kuyerera kwemvura. Mavharuvhu aya anotarisira kuyerera kwemvura, kumanikidzwa, midziyo yakasiyana uye kudzora kuyerera kwemvura iri pasi.
Kuziva kuyera saizi yevharuvhu yemashavishavi kunogona kudzivirira kusashanda zvakanaka uye zvikanganiso zvinodhura.
1. Zvinokosha zvevharuvhu yemashavishavi
1.1 Chii chinonzi vharuvhu reshavishavi? Vharuvhu reshavishavi rinoshanda sei?
Mavharuvhu eshavishavikudzora kufamba kwemvura iri mupombi. Vharuvhu yemapuruguru ine dhisiki rinotenderera rinobvumira mvura kuti ipfuure kana dhisiki ratenderera richienderana negwara rekuyerera. Kutenderedza dhisiki rakatarisa gwara rekuyerera kunomisa kuyerera.
1.2 Mashandisirwo akajairika
Mavharuvhu emashavishavi anoshandiswa mumaindasitiri akasiyana-siyana, anosanganisira mafuta negasi, mafekitori emakemikari uye masisitimu ekudzora kuyerera kwemvura. Anotarisira kuyerera kwemvura, anoparadzanisa michina uye anodzora kuyerera kwemvura iri pasi. Kugona kwavo kuita zvinhu zvakasiyana-siyana kunoita kuti akwanise kushandiswa pabasa repakati nepakati, pasi, pakupisa kwakanyanya uye pakumanikidzwa kwemhepo.
2. Ungayera sei vharuvhu reshavishavi?
2.1 Saizi yekutarisana
Saizi yekutarisana inoreva daro riri pakati pezviso zviviri zvevharuvhu reshavishavi kana rakaiswa mupombi, kureva kuti, nzvimbo iri pakati pezvikamu zviviri zveflange. Kuyera uku kunovimbisa kuti vharuvhu reshavishavi rakaiswa zvakanaka mupombi. Zviyero zvakarurama zvekutarisana zviso zvinogona kuchengetedza kusimba kwehurongwa uye kudzivirira kubuda kwemvura. Kusiyana neizvi, zviyero zvisina kururama zvinogona kukonzera njodzi dzekuchengetedza.
Zvinenge zviyero zvese zvinotsanangura kukura kwemavharuvhu eshavishavi. Inonyanya kushandiswa ndeye ASME B16.10, iyo inotsanangura kukura kwemarudzi akasiyana emavharuvhu eshavishavi, kusanganisira mavharuvhu eshavishavi. Kutevedzera zviyero izvi kunoita kuti zvienderane nezvimwe zvinhu zviri musystem yemutengi iripo.
2.2 Kuyera kumanikidzwa
Kuyera kumanikidzwa kwevharuvhu remashavi kunoratidza kumanikidzwa kwakanyanya kunogona kutsungirira vharuvhu remashavi pavanenge vachishanda zvakachengeteka. Kana kuyera kumanikidzwa kusina kururama, vharuvhu remashavi ...
Mavharuvhu eButterfly anowanikwa mumhando dzakasiyana dzemadhigirii ekumanikidzwa, ayo anowanzo tangira paClass 150 kusvika kuClass 600 (150lb-600lb) zvichienderana neASME standards. Mamwe mavharuvhu eButterfly ane hunyanzvi anogona kutsungirira kumanikidzwa kwePN800 kana kupfuura. Sarudza kumanikidzwa kwesystem zvichienderana nezvinodiwa zvekushandisa. Kusarudza kumanikidzwa kwakakodzera kunovimbisa kushanda kwakanakisa uye hupenyu hwebasa revharuvhu reButterfly.
3. Vharuvhu yeshavishavi ine dhayamita yezita (DN)
Dhayamita yevharuvhu remashavishavi inoenderana nedhayamita yepombi yarinobatanidza. Saizi chaiyo yevharuvhu remashavishavi yakakosha mukuderedza kurasikirwa nekumanikidzwa uye kushanda zvakanaka kwesystem. Vharuvhu remashavishavi risina kukura zvakanaka rinogona kukonzera kudzika kwemvura kana kudzikira kwakanyanya kwepressure, zvichikanganisa mashandiro esystem yese.
Mitemo yakaita seASME B16.34 inopa gwara rehukuru hwevharuvhu remapuruguru, ichivimbisa kuenderana uye kubatana pakati pezvikamu zviri mukati mehurongwa. Mitemo iyi inobatsira kusarudza saizi yakakodzera yevharuvhu remapuruguru yekushandiswa kwaro.
4. Kuyera Saizi Yechigaro
Iyochigaro chevharuvhu yeshavishaviSaizi ndiyo inosarudza kukodzera kwakakodzera uye kushanda kwevharuvhu reshavishavi. Kuyera kwakarurama kunoita kuti chigaro chikwane muviri wevharuvhu. Kukwana uku kunodzivirira kubuda kwemvura uye kunochengetedza kusimba kwehurongwa.
4.1 Maitiro ekuyera
4.1.1. Yera dhayamita yegomba rinosungirirwa (HS): Isa caliper mugomba uye yera dhayamita nemazvo.

4.1.3. Yera ukobvu hwechigaro (CS): Shandisa caliper kuyera ukobvu hwechikamu chimwe chete chakatenderedza mupendero wechigaro.
4.1.4. Yera dhayamita yemukati (ID) yechigaro chevharuvhu: Bata micrometer pakati pechigaro chevharuvhu.
4.1.5. Sarudza dhayamita yekunze (OD) yechigaro chevharuvhu: Isa caliper pamucheto wekunze wechigaro chevharuvhu. Tambanudza kuti uedze dhayamita yekunze.
5. Kupatsanurwa kwakadzama kwehukuru hwevharuvhu reshavishavi
5.1 Kureba kwevharuvhu yeshavishavi A
Kuti muyere kureba A, isai caliper kana tepi yekuyera pakutanga kwechikamu chekupedzisira chevharuvhu remashavishavi moyera kusvika pamusoro pechitsiko chevharuvhu. Ita shuwa kuti chiyero chacho chakafukidza hurefu hwese kubva pakutanga kwemuviri wevharuvhu kusvika kumagumo echitsiko chevharuvhu. Chiyero ichi chakakosha pakuona saizi yese yevharuvhu remashavishavi uye chinopawo chirevo chekuti mungachengetera sei nzvimbo yevharuvhu remashavishavi muhurongwa.
5.2 Dhayamita yevharuvhu yeplate B
Kuti muyere dhayamita yeplate yevharuvhu B, shandisai caliper kuyera daro kubva kumucheto kweplate yevharuvhu, muchinyatsoteerera kupfuura nepakati peplate yevharuvhu. Diki zvikuru richadonhedza mvura, yakakura zvikuru inowedzera torque.
5.3 Ukobvu hwemuviri wevharuvhu C
Kuti muyere ukobvu hwemuviri wevharuvhu C, shandisai caliper kuti muyere daro riri pamuviri wevharuvhu. Kuyera kwakarurama kunoita kuti pave nekushanda kwakakodzera uye kunoenderana zvakanaka nehurongwa hwemapaipi.
5.5 Kureba kweKiyi F
Isa caliper pamwe chete nehurefu hwekiyi kuti uverenge hurefu hweF. Chiyero ichi chakakosha kuona kuti kiyi inokodzera zvakanaka kuactuator yevharuvhu yebhatafurayi.
5.5 Dhayamita yehunde (Kureba kwemativi) H
Shandisa caliper kuyera nemazvo dhayamita yehunde. Kuyera uku kwakakosha kuona kuti hunde yacho inokodzera zvakanaka mukati mechikamu chevharuvhu remapuruguru.
Saizi yeHole 5.6 J
Yera hurefu hwaJ nekuisa caliper mukati megomba wobva waitambanudza kune rimwe divi. Kuyera hurefu hwaJ nemazvo kunoita kuti zvive nyore kuti ushande nezvimwe zvikamu.
5.7 Saizi yeshinda K
Kuti muyere K, shandisai shinda yekuyera kuti muone saizi chaiyo yeshinda. Kuyera K nemazvo kunoita kuti shinda ienderane zvakanaka uye kuti pave nekubatana kwakasimba.
5.8 Nhamba yemaburi L
Verenga huwandu hwemaburi ari paflange yevharuvhu remashavi. Kukura uku kwakakosha kuti vharuvhu remashavi rikwanise kusungirirwa zvakasimba papombi.
5.9 Nzvimbo Yekudzora Kureba PCD
PCD inomiririra dhayamita kubva pakati pegomba rekubatanidza nepakati pevharuvhu kusvika pagomba rakapatsanurwa. Isa caliper pakati pegomba rerug wobva watambanudza kusvika pakati pegomba rakapatsanurwa kuti upime. Kuyera P nemazvo kunoita kuti pave nekurongeka kwakakodzera uye kuiswa musystem.
6. Mazano Anoshanda uye Zvekufunga Nezvazvo
6.1. Kuongororwa kwezvishandiso zvisina kururama: Iva nechokwadi chekuti zvishandiso zvese zvekuyera zvakaongororwa zvakanaka. Zvishandiso zvisina kururama zvinogona kukonzera kuyerwa kusina kururama.
6.2. Kusarongeka zvakanaka panguva yekuyera: Kusarongeka zvakanaka kunogona kukonzera kuverenga kusina kunaka.
6.3. Kusateerera migumisiro yekupisa: Funga nezvekuchinja kwekupisa. Zvikamu zvesimbi nerabha zvinogona kukura kana kupfupika, zvichikanganisa mhedzisiro yekuyera.
Kuyera zvigaro zvemavharuvhu eshavi reshavi nemazvo kunoda kutarisisa zvakadzama uye kushandisa maturusi akakodzera. Kutevera matanho aya kunoita kuti vharuvhu reshavi reshavi riiswe nemazvo uye rishande nemazvo mukati mehurongwa.
7. Mhedziso
Kuyera nemazvo saizi yevharuvhu yemashavishavi kunoita kuti pave nekushanda kwakanaka uye kusimba kwehurongwa. Shandisa maturusi akagadziriswa kuti upime nemazvo. Gadzirisa maturusi nemazvo kudzivirira zvikanganiso. Funga nezvemhedzisiro yekupisa pazvikamu zvesimbi. Tsvaga mazano enyanzvi kana zvichidikanwa. Kuyera nemazvo kunodzivirira matambudziko ekushanda uye kunatsiridza kushanda zvakanaka kwehurongwa.
